    Credit: Organometallics, 1996, DOI: 10.1021/om9503712 I recently came across this 2002 letter regarding still safety and lab emergency preparation from William J. Evans of the University of California, Irvine. I thought it was worth sharing again for its lessons learned: As described in the article “Putting Safety First,” my laboratory suffered major losses on July 23, 2001, as a result of a fire originating with the malfunction of a solvent still (C&EN, May 20, page 43).

  • Mass Media and Self-Promotion: Stephan's Law

    15 Dec 2014 | 3:53 am
    One of the recurring themes in engineering ethics is that power and privilege entail responsibility.  Those in positions of influence over millions of users of a technology should recognize the responsibilities that go along with such influence.  This is especially true of individuals and organizations that control mass media such as newspapers, radio, TV, cable systems, and entities such as Google and Facebook.  In this connection, I would like to bring to your attention a principle of human nature that I have observed in action on many occasions over the years.  To my…

    The bomb exploded as the car reached the intersection of Park Place and Forest Park Boulevard in Fort Worth, Texas.  The explosion was loud enough to be heard at an elementary school a couple of blocks away, and I was one of several students who got to the scene before emergency crews had cleaned it up.  From the front doors rearward the car looked nearly normal, but there was just a blackened pile of junk where the front end used to be.  The driver was killed instantly.  From what I recall, later investigation of this mid-1960s incident turned up ties to organized crime,…

    Earlier this month, President Obama asked the U. S. Federal Communications Commission (FCC) to classify the Internet as a public utility in order to preserve net neutrality.  While in principle the FCC is an independent regulatory authority, it usually takes the President seriously, and this proposed action led to both cheers and boos.  The cheering came from mostly liberal observers who see threats to the Internet coming from internet service providers (ISPs), who have expressed a desire to discriminate (either favorably or unfavorably) among their customers.  One form of…

  • The Downside of Adopting the Metric System

    curiouscat
    9 Dec 2014 | 12:25 am
    The only downside of adopting the metric system is less control over room temperature (based on my experience). Every ºC = ºF * 1.8 so have less control (when using only integers to control temperature as is the case in my experience). Granted this could be solved easily by using .5 (option in air conditioning and heating controllers but in my experience they don’t) for Celsius. For Fahrenheit this works out to enough control for me. For Celsius in a fair number (lets say 15%) of systems it is a bit uncomfortable. The specific circumstances add greatly to creating a problem. My guess…

    A recent report from the New York Fed looks at the economic benefits of college. While there has been a great deal of talk about the “bubble” in higher education the Fed finds college is very wise economically for most people. They do find a larger portion of people that are not getting a great return on their investment in higher education. That could well indicate students studying certain majors and perhaps some people with less stellar academic skills would be better off economically skipping college. Do the Benefits of College Still Outweigh the Costs? an analysis of the…

    British Columbia’s Engineering and Geoscience professional body, APEGBC, is conducting a survey for members on proposed changes to the bylaw regarding Continuing Professional Development Requirements.

    Engineers at a modern incinerator and crane system, known as “MVA Weisweiler,” in Eschweiler, Germany, needed to find a replacement for their festoon system that had been installed in 1996. Energy Chain cable carriers from igus were selected in the hopes of reducing required maintenance, while providing protection for the cables against the severe conditions the cable systems faced. Where cable carriers house, protect and guide cables and hoses, festoon systems keep cables dangling from static points. This allows dirt and dust to become caught in the system and leaves the cables…

    19 Dec 2014 | 1:00 pm
    If you live in Denver or have driven through it recently, you probably are more than aware that multifamily development is BOOMING in the City of Denver. I will use the word “multifamily” to define any apartment, townhome, or condo development. If the current City of Denver forecast is anything close to reality, this boom is here to stay for the next 5+ years. This boom is making profitable opportunities for not just the big developers but also many first time developers. This article is written more towards the developers (or potential developers) who want to start developing in…
  • Clearance of Steel Beams in a Crawlspace

    Jim Houlette
    16 Dec 2014 | 9:56 pm
    For any elevated structural you need to provide sufficient space below the framing members to meet code requirements.  But there are several other reasons why you should provide additional clearance. If you are building a structural floor with wood joists you must provide 18” clearance between the bottom of the joists to the soil by code.  Otherwise, other building materials such as steel beams may not have a clear definition of how much clearance should be provided. Typically, if you are building an elevated floor you may have poor soil conditions and therefore need to consider soil…

It is incumbent on the constructors and the agents to provide an overview of the building. They must also supply you the valuable knowledge pertaining to its location, facilities and structural designs. A verbal interaction with your agent cannot provide the sufficient information you need. This will demotivate you to invest your self-accrued finance on a doubtful venture. So the builders and their marketing staffs must focus on presenting a diligent and meticulous 3D presentation of…

    18 Dec 2014 | 4:58 am
    What in the world does a mixing company have to do with bourbon? Well let me tell you. Mixer Direct designs and makes equipment for numerous distilleries in the United States, The UK, and abroad. We are at heart a liquid mixing company and have engineers who are well equipped and educated on the craft. Mixer Direct is also conveniently located on the bourbon trail in Louisville, Kentucky. Coincidentally, nearly 95% of Bourbon is exclusively made in Kentucky.  The origins of bourbon are like a good mystery. Think Sherlock Holmes meets Pappy Van Winkle. Everyone seems to have an opinion,…
  • Stainless Steel Tanks

    16 Dec 2014 | 4:55 am
    A while ago, we delivered an order of stainless steel tanks to one of our customers here in Louisville. We took them several 25,000 gallon tanks. They were huge. Once the tanks were finally put into place, we got one of the strangest comments I’d ever heard in regards to our tanks. Our customer didn’t say “Wow! Those are massive!” or “I can’t believe you made them that fast.” He said, “Those are some good looking tanks.” “Large.” “Round.” “Silver.” Those are the words that I generally used to describe our tanks in my mind.
  • The History of Morphine

    Aaron Oneal
    11 Dec 2014 | 5:44 am
    May 2015 will mark the 210th anniversary of one of the world’s most controversial painkillers, Morphine. Morphine is classified as a narcotic. It is used as an anesthetic or as an analgesic. The famous narcotic has been surrounded by controversy since its inception around 1805. The contention surrounding the opiate stems from its highly addictive nature. It is also considered to be incredibly dangerous because of its hallucinogenic features and abusive recreational usage. Another major reason for the onslaught of controversy is rooted in its highly misdiagnosed use. Morphine…

    15 Dec 2014 | 8:41 am
    Your startup has fallen down the black hole of doom and there is no way out but to turn around and fight. First, let’s take a step back and talk about the Black Hole of Startup Doom. We first learned about it from our friends in the startup community. You may know it as the vortex of doom or, better yet, recognize it as the point where you and your team members begin losing faith in your startup. When faith starts to dwindle, so does passion and perseverance. As a result, startups begin to fall down a never-ending tunnel full of bad energy. And the only way out? Yep. You guessed it. You…
  • Design for Manufacturing: Sometimes the Coolest Products are the Hardest

    “Begin with the End in Mind.” This well-known Steve Covey habit is especially true during product development. I recently had the opportunity to speak about the early stages of product design at the Design for Manufacturing (DFM) Summit in Brooklyn, NY, discussing that without a clear understanding of product requirements from the start (as viewed from ALL stakeholder’s perspectives) most products are doomed to fail. And one of the biggest failure points happens when a large stakeholder, the manufacturer, is unable to manufacture efficiently. Let’s take a closer look at Design for…

In those pre-consulting roles, I often was the person responsible for finding, engaging and managing product development service providers (see my earlier post on choosing a product development partner.) In fact, my experiences as an engineering management executive inside a large product company were the basis for starting IPS, our own consulting firm. What…
  • The Four Truths About Real Innovation

    junef2013
    17 Sep 2014 | 10:40 am
    DON’T TRY TO INNOVATE BY YOURSELF AT HOME! Or anywhere else. When we think of genius inventors, we’re still inclined to envision the mad scientist in his lab, or the lone Einstein changing the world as we know it. But the myth of the solitary genius inventor (Einstein collaborated frequently) no longer serves the tech community. In its place is a new understanding of collaboration, in pairs and groups, as the next big competitive advantage. In fact, chances are that a solo innovation effort will not be as successful as a partnered one. A new book, “Powers of Two” by Joshua Wolf…

    October of last year marked the beginning of a new wave of generic Top-Level Domains (gTLDs) becoming available to domain registrars. This revolutionary change is very exciting for a computer geek like me. Some of you may ask, “Ok, so what exactly is a generic Top-Level Domain?”, Wikipedia states that: A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. It is visible to Internet users as the suffix at the end of a domain name. In…

  • Picking Caster Wheels For the Heaviest Loads – Nine Important Questions To Ask

    Tim Weber
    16 Dec 2014 | 10:47 am
    For decades, forklifts have been the heroes of the manufacturing plant. It’s hard to think of any production facility that hasn’t deployed these powered machines in one aspect of its manufacturing process. But increasingly, safety, liability and cost issues have spurred a movement to “forklift-free” production. In fact, an article in American Machinist documented the trend, and attempted to explain the pros and cons of such a shift. But one consideration that shouldn’t be overlooked is the selection of heavy-duty caster wheels on the pushcarts and manual machinery that will be…
  • Tiny Movements, Big Headaches: How TWERGO® Helps Move Industrial Carts, Inch By Inch

    8 Dec 2014 | 2:10 pm
    In a previous blog, we talked about simple changes you could make to a heavy assembly cart that would improve its maneuverability, and also increase its contributions to a more efficient manufacturing operation. But often, it’s the most minute of movements that have the greatest impact when trying to position your industrial cart into the precise location it is needed. Though many industrial carts get a “power-assist” by Automatic Guided Vehicles (AGV’s) or Human Operated Tuggers across a distance, it is these short and precise movements that often have to be performed manually.
  • Assembly Carts Bear The Brunt of Manufacturing’s Heaviest Trials – Are Your Industrial Casters Up to the Challenge?

    Ferris Ayar
    2 Dec 2014 | 6:12 am
    Assembly carts are manufacturing’s utility player – the lumbering linchpin of the factory, whether delivering materials used in the manufacturing process, or removing goods that are ready for sale. Such carts are a critical link in the manufacturing chain – often moving loads that tip the scales at thousands of pounds or more. With the cart itself adding hundreds of pounds to the equation, this results in a lot of weight that an individual has to handle at some point – singlehandedly having to push, pull, turn or maneuver the assembly carts and loads. This puts a tremendous amount of…

    Patented Heavy-Duty Caster Wheels Provide Relief That’s Easy On The Ears – And Your Wallet Industrial carts are critical to most manufacturing processes. They are like the lifeblood that runs through the veins of the production system. Almost anywhere you look in a plant, there is a cart zooming along, delivering parts or materials to a production area or removing finished goods. This process is continuous – in some robust operations, carts can be shuttling across three daily shifts. Of course, their presence is generally heard as well as seen – cart movement generally is accompanied…

    It often is surprising to people to learn of the multitude of applications for industrial casters – uses that might never have come to mind in spite of being in plain view. That’s because, generally speaking, the signature of a well-built, heavy-duty caster is that it is neither seen nor heard – casters quietly do their job while helping improve manufacturing productivity. Few examples epitomize this unique material-handling role than in a very unexpected application – pneumatic caster wheels, mounted beneath a stage that will support a halftime show during a Thanksgiving Day football…

  • Characteristic of Cumulative Compound Motor

    20 Dec 2014 | 9:30 am
    Generally in compound motor both series and shunt field exist. In this type shunt field is much stronger than series field winding. The compound can be classified into two types. They are Cumulative compound motor and differential compound motor. In cumulative compound motor the series field winding aids the shunt field winding. In differential compound motor series field opposes the shunt field. Therefore differential compound motor hardly used because of their meager torque characteristic at large load. The figure above shows that the circuit diagram of a cumulative DC Compound Motor.
  • Characteristic of a DC Series Motor

    19 Dec 2014 | 3:14 am
    The figure above shows the circuit diagram series motor. In series motor the current flows in the field winding and the armature are same. The armature current will increases whenever the mechanical load of the motor increase. As a result the flux will increase in the series motor when the armature current increases and vice versa.               Armature Torque Vs Armature Current: We know that Ta ∝ ΦIa Up to Magnetic Saturation Φ ∝ Ia, the armature torque Ta is directly proportional to square of the armature current (i.e.. Ta ∝ I2a). If armature…
  • Characteristics of DC Shunt Motor

    17 Dec 2014 | 1:30 am
    The three important shunt characteristic curves are 1. Torque Vs Armature current characteristic (Ta/Ia) 2. Speed Vs Armature current characteristic (N/Ia) 3. Speed Vs Torque characteristic (N/Ta) The fig above shows the circuit diagram of shunt motor. In this circuit the field winding is directly connected to the source voltage, so the field current Ish and the flux in a shunt motor are constant.   Torque Vs Armature current characteristic (Ta/Ia): We know that in a DC Motor Ta ∝ ΦIa. In this the flux Φ is continuous by ignoring the armature reaction, since the motor is working from…

  • Armature Reaction in DC Motor

    14 Dec 2014 | 3:01 am
    Similar to DC generator, armature reaction happens in a DC motor. This is often anticipated as a result of once current drifts through the armature conductors of a DC motor, it creates armature flux which on the flux created by the main poles. The polarity and direction of rotation of motor is same as that of generator, but the armature field direction is reversed. In a Motor the armature current flows against the back EMF Eb, whereas in a generator the armature current flows in the direction of the generated EMF Eg. As a result, it ought to be anticipated that for identical field polarity…
