Abstract: Disclosed herein is a composite co-fiber comprising a plurality of ceramic tows; one or more sacrificial yarns; where the sacrificial yarns are operative to undergo dissolution, decomposition or melting upon being subjected to an elevated temperature; and wherein the sacrificial yarns leave open spaces in the co-fiber upon being subjected to decomposition, dissolution or melting.

Abstract: The invention relates to flexible occlusion rendering, including receiving a first set of three dimensional image data including image data for a surface of interest and image data for a region occluding the surface of interest from a desired viewpoint. The purpose of this invention is to improve occlusion rendering via imaging by locating the occluding surface of the incoming three-dimensional data and, and modifying the characteristics of this data, to show the surface that is being occluded so that the image includes viewing through the occlusion to the surface of interest.

Abstract: A door supporting device comprising a low profile, compact, economically constructed frame made by bending a single flat piece of metal into four ninety degree bends; welding restricted to reinforcing of the ends, together with spot welding all threaded nuts to washers, and stems to rolling wheels; stabilizing said device by retracting its rolling wheels, allowing the entire width and length to make contact with the floor; and non-skid rubber on all contact points with the floor, to resist movement; desired movability and elevation of the door carrying service is adjustable.

Abstract: An adjustable, manually operated, table support system which allows the user to achieve various heights and angles of an attached surface ,while remaining seated where the surface load to the floor is distributed on four independent continuous posts. Each post is telescoping having a friction locking device attached to each. The locking devices are paired off and linked together on a actuation lever on each by a common connecting pin. This pin is in turn connected by a connecting rod to a rocker lifter situated above the two locks. Rockers of each leg unit are linked by a common actuating lever so that when force is applied to the lever both rockers rotate, lifting both connecting pins, and thus all four locks are actuated at the same time. A surface connecting system is incorporated whereby an attached surface will be allowed to rotate and slide on the telescoping posts to provide for changes of surface tilt angles.

Abstract: A slim-line portable hose ferrule crimper is formed by a bar with a pair of spaced parallel tracks extending from one side thereof. A movable crimping die holder holding a crimping die half is mounted on the tracks adjacent the bar, and is moved back and forth by a threaded screw passing through the bar and into the movable holder. A stationary holder for a complementary second die half confronting the movable holder is releasably secured at a fixed location on the tracks, but may be released by a pivoting latch to permit its removal from the apparatus.

Abstract: A device is disclosed which uses permanent magnets to manipulate charged ticle beams, such as those employed in traveling wave tubes, wigglers, and undulators. Tapered pole pieces are inserted between magnets in a periodic permanent magnet array, and the taper is oriented away from the beam path. The magnets themselves may also be tapered, but the taper is oriented toward the beam path. Tapering is described according to the cross sections formed when the plane which contains the beam path intersects the magnets and pole pieces.

Abstract: A method is described for manufacturing, shipping, and handling a process component of heat-exchanging, air-conditioning, and refrigerating circuits, such as a filter drier or an accumulator, so that the process component can be joined to fluid tubing of such circuits by field brazing, using phosphorus-bearing copper filler metal with little or no silver content to make the braze joints. The method finally comprises the steps of selecting the tubing used for the connectors with a diameter which is smaller than the diameter needed for the field brazing to the circuit tubing and then mechanically expanding the other end of the tubing from 2% to 20% to this field brazing diameter, whereby the tubing is work-hardened to a hardness of 45-50 F Scale Rockwell and is able to withstand damage from shipping and handling operations and thereby returns the critical tolerances needed by the field brazing.

Abstract: A combined filter and filter-drier, for the suction side of refrigeration and air conditioning systems, comprises a dual filter system straddling a cylindrical plug of dessicant. Upstream of the dessicant, a rigidly built primary filter assembly comprises an inlet deflector and a stepped filter. Downstream of the dessicant, a secondary filter assembly comprises an outlet filter pad which is compressed by a coaxially disposed spring near the inlet of the filter/filter-drier. The inlet deflector is preferably triangular in shape and is disposed transversely to the inlet.
