Abstract: Replicated x-ray optics are fabricated by sputter deposition of reflecting layers on a super-polished reusable mandrel. The reflecting layers are strengthened by a supporting multilayer that results in stronger stress-relieved reflecting surfaces that do not deform during separation from the mandrel. The supporting multilayer enhances the ability to part the replica from the mandrel without degradation in surface roughness. The reflecting surfaces are comparable in smoothness to the mandrel surface. An outer layer is electrodeposited on the supporting multilayer. A parting layer may be deposited directly on the mandrel before the reflecting surface to facilitate removal of the layered, tubular optic device from the mandrel without deformation. The inner reflecting surface of the shell can be a single layer grazing reflection mirror or a resonant multilayer mirror.

Abstract: The invention comprises a swing platform assembly for the safe securement and accommodation of a pair of user's feet, regardless of the size of the user, to permit the user to stand on the swing platform assembly for recreational swinging. The assembly comprises a planar panel of generally rectilinear configuration having an upper surface, a lower surface, a forward and a rearward edge, and a pair of side edges. A pair of support lines are arranged through an opening adjacent each of the side edges to permit the platform assembly to be supported off of the ground. A pair of elongated, generally parallel, multi-size foot-accommodating recesses are molded into the upper surface of planar panel, to allow any size foot to be maintained securely therein while swinging standing, without slippage of a user's foot from the swing assembly.

Abstract: Spun yarns are made at high speeds of up to 220 meters per minute, using spinning techniques in which air is used to twist the fibers of a three component blend, one component of which consists of staple fibers made from electrically conductive filaments having a denier no greater than 2.5 times the denier of the filaments of the other components.

Abstract: An air distribution housing in an automotive air conditioning system includes spaced wall portions forming an air passage for flow of conditioned air into the passenger compartment of a motor vehicle; each of the wall portions having pins directed internally of the wall portions without forming openings therethrough and including distal ends thereon inserted into a tubular end portion of the valve member for pivotally supporting the valve member within the air passage without penetrating through the spaced wall portions so as to prevent air leakage and resultant noise from the air distribution housing. A method of assembly of the air distribution housing includes the steps of providing two separate housing parts with integrally formed pins on the inner surfaces thereof; providing a valve door with a pivot tube on one end thereof; vertically locating one end of the tube on one of the pins; thereafter joining the housing parts to locate the other pin in the other end of the pivot tube.

Abstract: A one-piece molded clamp having two portions connected by a living hinge defines cylindrical passages for two pipes and annular grooves for receiving beads on the pipes. A locking tang on one portion engages a mating cavity on the other portion to hold the clamp closed. The pipes pass through apertures in a wall and the clamp is mounted to the wall by a fastener passing through the clamp. Outstanding ribs on the wall hug the outer surface of the clamp to assist the locking tang in holding the clamp closed. A foam seal with a rubber surface layer is compressed between the clamp and the wall to prevent leaks through the wall apertures.

Abstract: A woven fabric of yarns spun from poly(m-phenylene isophthalamide) staple fiber has been designed to provide protective garments of improved comfort.

Abstract: A heater core is mounted over an opening in a wall of a heater and air conditioner case and secured by a single spring steel strap having a straight portion extending parallel to the tubes of the core and bearing on the header flanges. The strap has terminal hook portions which engage anchor apertures in the web outboard of the core. The apertures have flanged edges for engagement by the hook portions and the strap is manually flexed for engagement or disengagement of the hook portions during installation or removal of the strap so that no tools are required. One embodiment has a hook on one end of the strap and a snap fastener on the other end. Another embodiment has identical hooks on both ends of the strap.

Abstract: A vehicle heating and cooling system has a distribution duct separated into two channels by a baffle for supplying separate air streams to the passenger and driver sides of the vehicle compartment. Two temperature control doors associated with the heater core and evaporator separately admit an air mix to the two channels for independent control of driver and passenger side temperature. Optionally a single door is used in place of the two temperature control doors so that at the time of manufacture the system can be configured as a single zone system. A rear air discharge opening is provided in one of the channels to supply a duct leading to the rear seat region of the vehicle compartment.
