Abstract: The present proposal comtemplates an anti-theft device for unattended trailers, in the nature of a cover-plate assembly for locking the open end of the trailer tow bar to prevent unauthorized removal of the trailer as by connecting the open end of the trailer bar to a peg on a towing vehicle. The assembly may comprise an underplate with a centrally disposed pintle and an apertured overplate or coverplate constructed and arranged to coact with the underplate to effectively prevent access to the opening at the end of the tow bar. For convenience, the two plates may be joined in spaced relationship as by a steel cable fixed at its ends, respectively, to the top side of the coverplate and to the reverse side of the underplate.

Abstract: In can manufacturing apparatus there is provided an overhead magnetic conveyor for transferring cans from a conveyor upon which they are coated to a conveyor upon which the cans are dried. To remove excess coating material which tends to form a bead around the lower most edge of a can, a bath of coating material solvent is disposed adjacent to the transfer conveyor and has within it an endless belt conveyor to which cans on the overhead conveyor are caused to fall and from which those cans are subsequently returned to the overhead conveyor. The upper, can carrying course of the endless belt conveyor is disposed at a predetermined depth below the surface of solvent within the cans so that excess material accumulating on the lower portions of the cans in the coating region is removed prior to entry of the cans into the drying oven.

Abstract: A modular assembly of reciprocating electric generators with respective movable floats and a common submerged damper plate and buoyancy chamber produces electricity from wave motion on a body of water.

Abstract: A retractable ballpoint pen has a body and a point secured to a flexible tubular ink reservoir. The ink reservoir is secured to a rotatable element within the body, movement of which element causes the pen to be retracted and projected and during that movement the reservoir follows a generally circular path.

Abstract: An electronic musical keyboard instrument has a unit separate from the main console and having switching means for performing the function of at least some of the keys and stops of the console that unit being adapted to be operated by a handicapped person.

Abstract: The invention relates to a press, especially for pressing straw material into briquets. The press has a number of press chambers open at either end and a number of pistons, the press chambers and pistons being connected to guiding means and driving means so that the pistons are moved inwards and outwards in relation to the press chambers at one end thereof for introducing press material in portions, pressing the press material and moving it to the other end of the press chambers where it is delivered. The pistons have a smaller outer extent than the inner extent of the press chambers in the engagement region of the pistons. Hereby some advantages are obtained.

Abstract: Air quench extrusion apparatus and method are described for extruding yarn from polyolefin material. The yarn is first extruded downwards into a hot zone surrounded by a shroud, and then passes through a quenching zone across which cooling air, or gas, is moved to cool the yarn. Immediately adjacent the lower end of the quenching zone is disposed a denier control roll for pulling the yarn out of the quenching zone at a controlled rate causing the yarn to be drawn down in denier in the hot zone. The hot zone is small in volume relative to the quenching zone and contains quiescent air at a temperature close to that at which the material is extruded. The height of the apparatus from extrusion to the denier control roll is less than 10 feet, allowing the apparatus to be located in a single story building. At least two multi-filament yarns are simultaneously extruded into the hot zone which is rectangular in cross-section.

Abstract: A brick comprising in combination a body element having oppositely disposed ends and spaced apart surfaces intermediate the ends, with the body element having a pair of elongated cavities extending between the oppositely disposed ends and through the spaced apart surfaces and a channel extending between the cavities. An aperture extends between each cavity and a respective one of each of the ends. Electrical lighting components are mounted in each of the cavities and include a light bulb socket secured to a wall of the cavity, a light bulb secured in the socket, first electrical wires connected to each light bulb socket through the channel, and second electrical wires connected to each light bulb socket and exiting from the body element through each aperture, such that adjacent bricks may be wired together.

Abstract: A bulkhead for a swimming pool has a simple, lightweight frame, improved movability within the pool and means for suppressing the ill effects of waves produced by a swimmer nearing the bulkhead.

Abstract: A mincing machine, especially a meat mincing machine, of the type which has a rotatable knife disc 1 in front of a disc 2 with holes, and means for feeding mincing material including bone fragments to the knife disc and pressing out minced material minus the bone fragments through the disc having apertures, said knife disc and disc with apertures being arranged in a housing, characterized in that the housing in the region adjacent the knife disc has at least one recess constructed and arranged to receive and relinquish said bone fragments contained in the meat.

Abstract: A system for converting an electrical signal to a number of pulses and counting those pulses to provide a digital signal related to the average of the original electrical signal. An accurate electronic clock is included to provide time information and to determine the period of measurement and of averaging. Digitized signal, average, and time information are displayed and provided for interfacing with other digital equipment. An output analog signal is derived alternately from the digitized input signal and from its average.

Abstract: A fabric composed of a fleece or backing of fibrous material with parallel rows of single thread, sewn-knitted, run resistant, stitches superimposed thereon; a method of making the fabric and a warp knitting machine which is suitable for the production of the sewn-knitted fabric.

Abstract: A multiple sensing device has sensors, mounted on a common rotatable shaft, for sensing magnetic field, electric field, gas flow, angular acceleration and linear acceleration. The latter three of the sensing devices employ piezo electric crystals as the sensors, while the magnetic field sensor employs a pair of rotating coils and the electric sensing device employs a pair of rotating electrodes.

Abstract: In a hemodialysis system including a dialyzer having a semi-permeable membrane, apparatus for accurately proportioning and mixing fluids comprising a double acting piston/cylinder unit of which the cylinder is divided into two chambers by the piston and the volume of the cylinder swept by the piston at one end of the piston is lesser than that at the other end. An inlet connection for first liquid is made to one chamber, a conduit connects the two chambers and includes a connection to a source of the second liquid. Valve means are associated with the conduits and are effective to cause a charge of first liquid to be delivered to the one chamber and thereafter to be transferred to the other chamber, drawing liquid from the source of the second liquid to make up for the difference in volume. Said valve means then cooperate to cause the mixed liquids to be discharged from the other chamber as said one chamber is again charged with said first liquid.
