A method for manufacturing a discontinuous fiber reinforced glass matrix composites by injection molding using an injection nozzle that separates substantially all of a multifilament yarn into individual fibers resulting in a composite having greater crack resistance. The method comprises impregnating continuous filament yarn with glass matrix powders comprising glass, glass-ceramic powders or a mixture thereof. The impregnated multifilament yarn is chopped into discontinuous lengths and exposed to a temperature sufficient so that the matrix material softens. Pressure is applied to the heated impregnated multifilament yarn sufficient to displace the yarn into a mold through an injection nozzle contoured such that sufficient die-wall shear forces are generated to separate substantially all of the multifilament yarn into individual filaments. A mold pressure is maintained sufficient to prevent relaxation of the composite until the strain point of the glass is reached.

An improved cryopump has cryopanels with pressed zeolite plates mounted thereon. The plates are maintained in intimate but unbonded contact with the panels by use of spring-type mechanisms. Older style panels have clay-bonded zeolite casts attached to their surfaces. The new configuration allows relative expansion and contraction between the zeolite plates and the panels, thereby improving durability of the zeolite. The resilient attachments assure that intimate contact and consequent good cooling of the zeolite adsorptive surface will be maintained during operation of the pump. The zeolite panels are desirably less than about 8 mm thick and are made by isostatic compaction of powders having pore sizes in the range of 2-25. times. 10. sup. -10 m.

A heat pump system, utilizing a multi-component refrigerant blend in which a low pressure component is zeotropic with respect to the remainder of the blend, separates the low pressure component by rectification to enhance heating capability in low ambient temperatures. Vapor is separated from liquid in the effluent of the condenser of a heat pump, at a pressure in equilibrium at a temperature midway between the evaporator and condenser effluent temperatures, the vapor being applied to an auxiliary inlet at a mid pressure point in the compression stroke of the compressor.

A cryopump having a cryopanel adapted for being cooled by a first refrigerant and shielded from radiation incident thereon by shields adapted for being cooled with a second refrigerant is disclosed. The cryopanel and the radiation shield are fabricated with a first material having high thermal conductivity, such as aluminum, while means for distributing refrigerant from refrigerant dewars to the cryopanel and shields are made of a second material, such as stainless steel. The stainless steel and aluminum sections are connected by an aluminum-steel transition connector adapted for providing vacuum tight connections at cryogenic temperatures. Both the cryopanel and chevrons comprising the shields are fabricated and extruded aluminum with coolant passages formed therein. Thermal distortions during operation are compensated by the use of stainless steel bellows within refrigerant distribution lines. Additionally the refrigerant distribution lines are utilized to suspend the cryopanel and shields within an evacuated environment of the cryopump.
