Abstract: A water hose particularly suitable for home and garden use, as well as light industrial or commercial use. The hose has a composite form and contains multiple bonded layers that synergistically contribute to durability, flexibility at a wide range of temperatures, kink resistance, and excellent flow rates while being relatively light in weight as compared to some conventional multi-layer composite hoses.

Abstract: In an epitaxial reactor system using a vacuum pump which is connected to the reaction chamber by an exhaust line, particulate contaminants normally deposit in the exhaust line near its juncture with the reaction chamber. When the vacuum pump is isolated from the reaction chamber during a back-filling operation, these contaminants can be entrained in the currents of gas normally produced in the back-filling operation. A removable baffle device having the shape of a truncated cone and including a wafer catching device that holds a disk shaped particulate baffle member is placed in the exhaust line at its juncture with the reaction chamber to prevent these particles from re-entering the reaction chamber.

Abstract: A suspension system for hanging a susceptor inside a reactor for processing semiconductor wafers. A hanger is provided with a flange at its lower end for supporting the susceptor. A collar has an internal flange which engages with another flange at the upper end of the hanger. The collar flange and the hanger flange each have a trucated, conical contact surface which are in substanitally continuous contact with each other. The mating flanges permit the susceptor to self-center and provide for different rates of thermal expansion of the collar and hanger.
