Improved Gas Flow Monitoring in Heat Treating Processes Leads to Higher Efficiencies and Lower Costs (.pdf)
It can be difficult at times to accurately monitor the use of consumables in many heat treating processes. A lot of the existing technology falls short when it comes to. being highly accurate, capable of measuring a broad flow range, suitable to various gases, and economical enough to be used

Combination Products: Navigating Two FDA Quality Systems
By Steven Richter, Ph.D., Microtest Laboratories, Inc. The combo product manufacturer s largest challenge will be during the scale-up process, because additional quality control (QC) measures are required to determine the process scale-up parameter shift. During scale-up, combination products

Tech Transfer: Don't Fumble the Hand Off
products. Based on the drug s stability, the premixed products are either aseptically processed or terminally sterilized. Some products are frozen to enhance stability during shelf life. Products include penicillins, quinolones, cephalosporins and other sensitive molecules. Development, scale

Lords of the Ring
the falling scale and heat. For forging and heat treating, the furnaces were maintained to aerospace standards, including AMS 2750, Rev. D and those of the National Aerospace & Defense Contractors Accreditation Program (Nadcap). This means every thermocouple for each forging or heat-treating operation

The Sorbead Quick Cycle Process for Simultaneous Removal of Water, Heavy Hydrocarbons and Mercaptans from Natural Gas
that water and heavy hydrocarbons are attracted through molecular scale forces to the surface of the Sorbead adsorbent with a higher adsorption capacity than that of lighter hydrocarbons. As a general rule, the adsorption capacity is directly related to the molecular weight and boiling point of the gas

Carbon Steel
be microalloyed, but the technique was first used in sheet steel a number of years ago. More recently, microalloying has been applied to bar products to eliminate the need for heat-treating operations after parts are forged. Automotive and truck applications include connecting rods, blower shafts, stabilizer

Passivation vs. Electropolishing
to remove free iron or other foreign matter from the surface of the metal. Passivation, however, is not effective in the removal of heat tint or oxide scale as a result of heat treating or welding. Other than giving the part a clean finish, the process does not brighten or change the part appearance

Getting A Grip On Clutch And Brake Selection
Learn the basic steps for picking the best clutch or brake instead of waiting to learn them when a component fails. These graphs show two curves drawn to the same time scale. The curves represent clutch-torque buildup time and coil-current buildup time. This circuit shortens decay time. When

Atmospheric Plasmas Develop Hot Applications
Institute and Drexel's medical school have generated plasmas that can kill bacteria on living tissue without damaging the underlying cells. So bacteria that resist or are inaccessible to traditional heat sterilization and antibiotics can still be eradicated by plasma. The medical profession has known
