Abstract: A microscale chip cooling system for a heat dissipating item, such as Intel's Pentium brand microprocessor. The system includes a 40 millimeter by 40 millimeter thermally insulated housing including a base and a cover. The system also includes a thermally conductive evaporator. The evaporator is adapted to be attached to a heat source such as the microprocessor. The cover includes inlet and outlet ports and the base includes a capillary passage. A refrigerant or heat transferring fluid is pumped or past through the passage before making a sudden expansion in an expansion zone just before passing to an evaporator chamber. Pool and flow boiling and forced convection may occur in the evaporator chamber as heat is transferred from the microprocessor through the thermally conductive evaporator to the refrigerant. The refrigerant then returns to a compressor to repeat the cycle. The system is extremely small and very efficient.

Abstract: A process for making inner and outer ducts for a simple but effective plastic heat exchanger by a simple blow molding or thermoforming technique. Seals are formed by providing initially closed inner ducts which are stacked on one another and the end portions of the inner ducts are placed in a mold. A castable adhesive sealant is placed in the mold and around the stacked inner ducts. After curing, the mold and the stacked inner ducts are separated and a portion of the stack and a portion of the seal material are cut and removed. Thereafter, the outer duct is positioned about the stacked inner ducts so that two different flow paths are formed. Instead of molding the seal, a preformed seal may be press fitted to the stack of inner ducts.

Abstract: A plastic heat exchanger which is simple and inexpensive. The heat exchanger includes an outer duct and a stack of inner ducts, the inner ducts for establishing a first flow path for cooling air or air to be cooled. Each inner duct includes end portions which are stackable upon one another and a middle portion which has a reduced dimension. A seal is placed about each stack of end portions and a second flow path for cooled air or cooling air is formed within the outer duct, between the seals and around the outside of the middle portions of the inner ducts.

Abstract: A commutator employs superconducting switches to commutate currents in the field stator of a dc machine. The switches couple the machine's stator windings to a DC link. The switches are exposed to magnetic fields of alternating strengths, turning on and off in a sequence that maintains a constant torque angle between the stator's mmf vector and the flux vector of the machine's rotor or that rectifies a current induced into the stator by the machine's rotor.

Abstract: A turbopump which operates at cryogenic temperatures to pump cryogenic liquid fuels to high pressure, and which includes a rotating group supported on process fluid foil journal bearings and a hydrostatic and hydrodynamic foil thrust bearing. A back-face surface of a pump rotor reacts thrust forces to the foil thrust bearing and receives counter acting hydrostatic fluid forces dynamically moderated to achieve an equilibrium axial position and force balance.

Abstract: A rail fastener assembly includes a rail seat laterally shiftable incrementally to properly position a supported rail. Anchoring of the seat to an underlying foundation is achieved by a clamp ring surrounding the periphery of the seat and including a plurality of fastener-receiving openings having their centers variably spaced from the seat. Rotation of the clamp ring presents at least two fastener-receiving openings in overlying registry with hold-down elements in the foundation to enable the application of fasteners through the clamp ring to secure the seat to the foundation. A pair of symmetrical spring clips engage shoulders on the seat and include a medial hold-down portion biased against the rail flanges and fixed, distal shoulder engaging portions overlying each rail flange but normally spaced thereabove to limit deflection of the clips during vertical movement of the rail.

Abstract: A rail fastener includes a shoulder member fixed relative a cross-tie and having a head insertable through an apertured insulator. One end of the insulator bears upon the cross-tie while the opposite end carries a dielectric pad engaging the top surface and lateral edge of a rail base flange. The fastener assembly is completed by the application of a spring clip attached to the shoulder head and constantly bearing downwardly against the two opposite ends of the insulator. The dielectric pad surrounds a substantial portion of one end of the insulator and preferably is staked thereover but alternatively may be secured by a press fit, shrink fit, snap fit or by suitable adhesive.

The clip leg is joined to an arm bearing upon the anchor member with the arm then joined to an arcuate loop crossing over the mounting leg diagonally thereto. The clip terminates in a rail arm engaging the base flange of a rail with a substantial downward clamping pressure being applied thereto. The clip mounting leg may be an integral enlargement forming a diameter to provide a mating fit within a bore through the anchor member or alternatively, the clip mounting leg may support a separate sleeve having an outer diameter mating with the anchor member bore.

Abstract: An improved hose construction and method of forming the same wherein a reinforcement layer is bonded to a thermoplastic core by a solventless bonding layer defining an inner thermal weld portion substantially autogenous with the outer surface portion of the core tube and an outer portion mechanically interlocked with the confronting inner portion of the reinforcement layer.The bonding layer is thermally formed to be autogenous with the outer surface portion of the core tube and may include an added layer of thermoplastic material which is concurrently fused to define the fused bonding layer. The added layer is compatible with the core tube outer surface portion and is preferably formed of similar thermoplastic material. The reinforcement layer is wrapped about the core tube under tension to provide an embedment thereof in the bonding layer to effect a positive mechanical interlocking therebetween.
