Abstract: A hydrogen-hydride absorption system comprising two reactor systems for chemically forming two hydride components, means for supplying heat to, and removing heat from, the component systems, means for partial thermal energy recovery from reactors in each of the systems, and means for conveying hydrogen between component reactor systems.A method for deriving refrigeration includes the steps of dehydrating the hydride of a first component reactor using a relatively low temperature thermal source and conveying the hydrogen to a second component reactor to be absorbed, and rejecting heat, decreasing the pressure of both component reactors along with partial heat recovery, supplying heat as a refrigeration load to dehydride the second component reactor and conveying the hydrogen to the first component reactor, and pressurizing both reactors through partial heat recovery and further heating.

Abstract: The present invention is related to a mechanism for gauging the expansion of a trawl net in correspondence with the number of fish caught within the trawl. The mechanism includes sensors adapted to be fastened to the .[.masks.]. .Iadd.meshes .Iaddend.of the trawl net in order to sense changes in the geometry of the .[.mask.]. .Iadd.meshes.Iaddend.. Each sensor includes a permanent magnet and a reed contact disposed to be activated by the magnet as a result of a predetermined trawl net expansion, thereby transmitting a signal indicative of such expansion to a detection and indication mechanism located on board an associated trawler.

Abstract: A tensioning apparatus for an endless power transmission device is provided and utilizes the elastic properties of an elastomeric material to provide the tensioning action and such apparatus is supported adjacent the endless power transmission device to be tensioned and has components thereof operatively associated with the elastomeric material and with the device.

Abstract: An epoxy tape useful as an adhesive sealant comprised of a first band of an uncured epoxy resin composition and a second band comprised of a composition capable of curing the epoxy resin. Kneading together of substantially equal lengths of opposed portions of the first and second bands results in an epoxy composition which is self-curing.

Abstract: The process and apparatus for continuously forming glass fiber reinforced products employs a preform produced by drawing continuous glass fibers through a resin bath and stripping die. This preform is then compressed during passage through an elongate molding zone. The molding zone is formed of two, articulated die cavity-containing tracks, the individual mold components of which join at the threshold of the zone to form an elongate, moving compression stage. This stage may be heated to carry out curing of the product during compression thereof.

Abstract: Pipes with walls thicker than 4 mm are made by paste extrusion of PTFE powder in the presence of a lubricant. The extrusion is carried out at a reduction ratio below 20:1. The PTFE powder is a mixture of 80 to 99% by weight of coagulated dispersion grade PTFE and 20 to 1% by weight of PTFE having a median particle size less than 50 micrometers. The mixture is preferably a co-coagulation of the two forms of PTFE.

Abstract: A one-piece body suit of insulated construction with enlarged upper sleeve segments which permit retraction of the wearer's arm to a position alongside the upper torso preparatory to hand extension out openings located along the length of the sleeve. Hand covers are integral with lower sleeve segments and include an elastomeric coating over individual finger sheaths. Each sleeve includes Velcro closure pieces serving to retain the vacated lower sleeve segment in a folded back position alongside the upper sleeve segment.

Abstract: A protective enclosure for the human ear entirely closed except for a single opening sized to receive the outer ear. This opening is surrounded by a band of pressure sensitive adhesive to anchor the enclosure to the skull in a fluid tight manner. The opposite lateral edges of the enclosure are pleated inwardly to receive the operator's fingers in areas closely spaced to the adhesive while installing the enclosure over the ear.

Abstract: Single or double-leaflet heart valves include leaflet valve members which are arcuate in cross section, preferably being essentially a portion of the wall of a circular tube. Generally spherical sectors protrude oppositely from the leaflets and are received in elongated, complementary depressions in the interior wall of the annular valve body at generally diametrically opposite locations. As the leaflets pivot between the open and closed positions, the guides move from one end of the elongated depressions to the other. Eccentric pivot axes provide for quick response of the leaflets, and their arcuate shape coupled with shifting of the axes during pivoting moves the leaflets out of the center of the valve passageway reducing resistance to the free flow of blood.

Abstract: Article used in a method for sanitizing toilets wherein a hypochlorite sanitizing agent and an oxidizable dye are dispensed from separate dispensing means into the toilet flush water to provide a color to the bowl water. The color disappears within a short time after the flush, thereby providing a visual indicator of the activity of the sanitizing agent.

Abstract: A fitted top sheet includes a construction which provides a foot accommodating space when placed in position on a mattress. The sheet has a one piece construction wherein the fitted bottom corners and foot accommodating space are formed by sewing the cut edges of two cut-outs in each side of a generally rectangular piece of material.

Abstract: Process for the prevention of chalkbrood disease amongst leafcutter bees (Megachile species) including the step of dusting the entrance of nesting holes with sodium sulfathiazole whereby incoming bees must come in contact with the powder upon entering the hole. Where old, previously used, beeboards are used as nesting holes, the process includes cleaning debris from the nesting holes and scouring the board with a dilute solution of calcium hypochlorite before applying the sodium sulfathiazole.

Abstract: Ice tool with a handle formed from the shaft providing clearance for the user's hand when the shaft is parallel and adjacent to an ice surface. The tool having a pick and spike for imbedding in the ice surface and a means for attachment of a line. A force supplied to the line further imbeds the pick and spike into the ice surface.

Abstract: A harness device for supporting a person, such as a child or mentally or physically impaired person, in the water includes a wide chest band which is adjustable in length and lockable in any adjusted position. The device also includes a pair of shoulder straps secured to the upper end of the chest band on opposite sides thereof and which are adapted to extend over the person's shoulders. Each of the shoulder straps is adjustable in length and lockable in any adjusted position. The harness device also includes a pair of leg straps secured to the lower end of the chest band and adapted to extend around the person's legs at the crotch. Each of the leg straps is also adjustable in length and lockable in any adjusted position. The opposite ends of one of the leg straps is directly secured to one side of the chest band and the opposite ends of the other one of the leg straps is directly secured to the other side of the chest band. The device also includes a hand grip secured to the back of the chest band.

Abstract: A protective device is provided for a front face deburring of workpieces or profiles, particularly pipes, in a deburring machine having a rotating tool, e.g., a brush or a grinding wheel, or the like, which acts on the workpiece. The device includes an adjustable retaining means mountable on a workpiece retainer means in front of the rotating operating tool for receiving an upstanding interchangeable protective guard and guide plate having an opening for the workpiece.
