Plastics Processing Applications: Textile Fiber Production
Typically the production of manmade colored textile and carpet fibers involves the feeding of two or more components into a single screw extruder, where they are mixed and extruded as a filament. Filament pumps, nozzles and further processing equipment ensure the fibers have the correct form

Design / Installation Notes: Shortwave Emitters (.pdf)
emitters infrared source is from a tungsten filament located in the center of the emitter. The protective element that surrounds the tungsten in made from clear fused quartzglass. This is evacuated and sealed and provides protection for the filament from oxygen, and provides against convection

Infrared Basics
the ability to instantly turn on and off, and the ability to focus the energy. The differences are that a quartz envelope is used (instead of glass) and the filament if larger, which improves lamp life and increases the emitting area. The quartz halogen lamp (see Figure 1) consists of a helically wound

Lube-for-life journal bearings
on a sintered structure but the lubricant is embedded in the reinforcing matrix. Such bearings have fairly limited life and are typically found in applications that can accommodate significant bearing wear. Composite bearings from Polygon Co., Walkerton, Ind., combine a high-load continuous-fiberglass-filament

Improvements in Low Power, End-Window, Transmission-Target X-Ray Tubes
consistent performance from tube to tube. 2) Changes in the anode geometry have resulted in reduced spectral contamination from metal parts in the anode. 3) The electron beam position on the anode is primarily influenced by the filament placement relative to the cathode optic. Using finite-element

Product Technology News
is a continuous-filament nylon wiper that dissipates electrical charges to a measurable surface resistivity of 106 (omega). The wiper needs no humidity or ambient moisture to be effective. Its uniform dissipative surface and body eliminates potential hot spots of charge. The wiper contains no carbon-filament grid
