Abstract: Liquid crystals having color play centered at different temperatures are arranged in a similar pattern on metal coated and non-metal coated disks which are used to monitor electromagnetic radiation. An embodiment which measures radiation in the range of 1 to 15 mW/cm.sup.2 at 2.45 GHz is described. The monitor uses the temperature-dependent light scattering properties of liquid crystals as the measuring and indicating mechanism. While both disks will respond equally to changes in ambient temperature, the metal coated disk also responds to induced temperature changes caused by incident radiation. Thus the difference between the temperature indications of the two disks is a measure of the radiation present.

Abstract: A plow system includes a number of individual plow units mounted on a beam which is inclined relative to the direction of travel of a traction vehicle. The units are mounted for continuous rotation about vertical axes so that they may be opened or closed to adjust the width of a cut between adjacent units over a continuous, wide range. The plow unit is supported by a forward furrow wheel located to ride in previously-plowed ground and a rear furrow wheel, and the main frame is pulled by a tongue or draft member connected between a tractor hitch and an intermediate location of the inclined beam. A hydraulic unit adjusts the individual plow units in unison, and at the same time, through a linkage, adjusts the tongue relative to the inclined beam to keep the forward furrow wheel at a constant distance from the rear tractor wheel for all width adjustments.

Abstract: A method of making a pipe fitting havin three or more legs arranged in any desired shape by deforming a malleable metal tube substantially filled with a constant volume filler material in a single step without the need for secondary bending while maintaining the filler material at constant volume to provide a fitting wherein the variation in wall thickness is less than about 10%.

Abstract: An instrument particularly useful for locating and removing ureteral calculi and other occlusive objects from body passages. The instrument includes a flexible tube or sheath which slidably receives a tightly-twisted multi-stranded cable of a length greater than that of the tube, the cable having an integral cage portion at its distal end. That cage portion, which is normally collapsed and concealed within the distal end of the tube, may be extended beyond the tube to assume an expanded helical pear-shaped configuration for ensnaring and withdrawing ureteral stones and other passage-occluding bodies. The tightly wound strands of the cable are arranged in a circumferential pattern about an axial lumen which in one embodiment is useful for fluid drainage and injection and which in other embodiments accommodates conductors for transmitting light, images, and/or ultrasonic energy.

Abstract: A releasable lock for a wearable device such as a hammer tooth or chain shackle in which two parts of the device are held together by means of a pin, the pin further being immobilized by a deformable rivet, the rivet extending through a transverse bore in the pin.

Abstract: A tubular pylon secured to a deck is provided with a core telescopically and slidably received in its distal end. In securing the deck to the hull, a well is provided in a shoe to be received in and secured to the hull. Glue is inserted in the well and applied along the intended glue seam between the deck and hull. The deck/pylon assembly and hull are then assembled to be clamped in a jig. During assembly, the core acts as a plunger to force glue in the well of the shoe upwardly about the outer surface of the pylon to secure the pylon to the shoe. The core is frictionally held by the pylon to exert a desired force in holding the shoe against the inside of the hull while the adhesive sets to secure the shoe to the hull and the deck to the hull.

Abstract: An air flow amplifier of relatively high air flow amplification ratios in which a thin film of pressurized primary air flowing in a transverse direction is mechanically deflected to impinge on a generally frusto-conical surface tapering towards the throat of the amplifier. The deflecting action is produced by a deflection ring which is spaced inwardly from the amplifier's annular nozzle. The ring has an internal diameter substantially larger than the amplifier's throat so that secondary air entering through the ring may flow directly towards the frusto-conical surface to mix with the primary air flowing along that surface.

Abstract: A temporary door installation for a grain carrying freight car wherein the pry board is upwardly tapered to eliminate the need for special sealing.

Abstract: The system includes a flexible button top which has a sleeve appurtenance which is force-fitted over an externally helically grooved stud assembly having an integral self-adhesive back mounting plate. The button top is flexible enough so that it can be applied to, and removed from the stud assembly without the use of a tool, yet it is hard enough so that the stud will not perforate the flexible button top when impacted. The adhesive-backed stud assembly includes a helically threaded metallic screw perpendicularly attached to a metallic circular disc with a plastic foam backing impregnated with adhesive. The adhesive backing is covered by a release film prior to use. The adhesive-backed stud assembly can be applied without the use of a tool.

Abstract: A disposable unitary drape particularly suited for use in performing transurethral surgery of the bladder and prostate, and similar operations. A thin flexible finger cot projects from the body of the drape, the cot having a bulbous distal end portion and an elongated neck portion of reversed taper and reduced wall thickness. An annular retention rib projects outwardly from the cot at the juncture of the neck and end portions and, in one embodiment, the wall thickness of the neck portion is even further reduced in an arcuate intermediate section to increase tactile sensitivity in that zone for the surgeon. The cot may be supplied in longitudinally collapsed form. Because of its configuration and construction, the cot tends to be self-retaining in use.

The sheet is constructed of a disposable non-woven cellulosic material and the opening and the slot have folded edges formed by reversely folded portions of the material. A reinforcing sheet having a matching diamond-shaped opening and a matching slot can be secured to the main sheet in superimposed relation. The main sheet and the reinforcing sheet have respective openings and slots in direct alignment to define a fenestrated surgical drape having a pair of split end portions.

Abstract: A telescoping seating system has a plurality of row assemblies which may be extended for use or retracted to nested relation for storage. Each row assembly includes a pair of floor wheel channels. A post is mounted to each wheel channel; and a deck (which may include a riser beam) is connected between the tops of the posts. The invention enables the understructure configuration of all row assemblies to be similar. In a preferred form, the posts extend upwardly and they are inclined inwardly so that all posts on each side of the structure are parallel, and the connection between the posts and decks are in vertical alignment on each side. Thus, all row assemblies have a uniform center span. End cantilever spans beyond the posts are also equal for all row assemblies.
