Walton/Stout files for drying system patent
Walton/Stout Inc. of Lithonia, Ga., has filed for a patent on its gas-fired PET drying and crystallizing system, called the economizer.
The company claims the equipment uses 60-70 percent less energy than similar-sized electrically heated systems.
The dryer uses waste heat as an energy source.

Company mechanizes resin-defect testing
In the traditional way to test for defects in resin or compounded material, a technician manually presses pellets between two hot platens, then holds the sheet up to a light box.
Davis-Standard Corp. claims to have a better method: a system that makes cast film, then analyzes it.
Davis-Standard's new laboratory machine, the Killion Gel Count System, continuously detects defects and monitors for contamination in resin samples or extruded products such as film, sheet and medical tubing.
The system includes a KN125 extruder with a screw diameter of 11/4 inches and a coat-hanger die. The extruder processes 18-25 pounds of resin an hour.
A vision system mounted above the film can be programmed to detect defects as small as 12, 25 or 50 microns — defects the traditional method can miss.
Davis-Standard is based in Pawcatuck, Conn.

EPM 7000 monitors real-time processing
Epos Corp. of Auburn, Ala., is marketing a new EPM Series 7000 monitoring system for plastics processing in real time.
Series 7000 uses the Windows NT operating system and Microsoft SQL database. An industrial computer is mounted on each machine to be monitored.
The system monitors as many as 32 process parameters.

Parametric upgrades its Pro/E software
Parametric Technology Corp. issued its Pro/Engineer 20 software for computer-aided design and engineering. Pro/E 20 includes a new, easier-to-use interface, a new sketching tool and a three-dimensional Notes communication function.
The interface now has a menu bar that consolidates all top-level commands, a customizable tool bar and consolidated dialogue boxes.
An ``intent manager'' allows engineers to sketch ideas quickly, while the software makes assumptions and gives immediate feedback. Sketches always are set automatically to the correct dimension.
3-D Notes lets users easily display important product information within the context of the 3-D model.
The company in Waltham, Mass., also said it has repackaged its Pro/E Solutions, reducing its price.

Procedure measures film without contact
Filmetrics Inc. of San Diego makes a noncontact thin-film measurement system, the F20, that measures dielectric thin-film thickness, refractive index and extinction coefficient.
One customer, Diamonex of Allentown, Pa., bought an F20 to measure the thickness of carbon coatings on polycarbonate lenses. Using the F20, Diamonex technicians check 40-50 lenses per hour.
Diamonex's previous method, using a spectrophotometer, took 30 minutes to check just a single lense.
