Abstract: TITLE     IMPROVED LOAD CELL FOR ON-BOARD WEIGHING SYSTEMS     ABSTRACT         An improved load cell for logging trucks or similar vehicles.  The load cell is principally formed by a single cast or machines resilient beam including a relatively flat central portion connected to a pair of end portions through respective relatively thin intervening portions.  The end portions space the central portion from a support plate from which the end portions are welded.  The support plate is bolted to a frame of a tractor or trailer, and a bunk-sup-porting cross-beam, which was previously mounted on the frame, is secured to the central portion of the beam by bolts which tap directly into the central portion.  Strain gauges are secured to the undersides of the midsections to measure the load induced deflection of the beam.  A transverse slot is formed in the support plate adjacent the inner edges of the end portions to allow the inner edges to be welded to the support plate.

Abstract: TITLE TAMPER PROOF MOLDED PLASTIC CLOSURE           ABSTRACT OF THE INVENTION    A tamper proof molded closure is provided for use on a threaded bottle neck having an external peripheral bead below the threaded portion of the bottle neck.  The closure comprises a one piece molded cap having a circular panel portion and a depending annular skirt portion with the upper portion of the skirt defining internal threads and a lower band portion of the skirt defining an internal shoulder that is expandable to snap over the container bead during the assembly operation to lock the closure to the bottle neck.  At a region intermediate the threaded portion and the interior shoulder, the external wall of the band portion of the closure is scored to form a slit extending peripherally around the entire closure.   The depth of the slit extends through the wall of a closure at all points except for a limited number of peripherally spaced arcuate segments where the depth of the slit is less than that of the thickness of the skirt portion.  This provides connecting bridges between the threaded portion and the band portion of the closure which are readily severable by rotational movement of the closure in a direction to unscrew it from the bottle neck.  The slit height is limited to permit collapsing of the slit during the application of the closure to force the internal shoulder over the container bead.

Abstract: Abstract of the Disclosure A composite (10) which presents a layer (20) of ultra high molecular weight polyethylene as the wear resistant surface.  The polyethylene layer (20) is secured to a metallic backing plate (12) by virtue of an elasto-meric layer (13) that is interposed between the metallic backing plate (12) and the polyethylene layer (20) and is bonded to each without the polyethylene and the metallic backing plate being otherwise bonded to each other.  This configuration provides a means by which to mount a wear resistant polyethylene layer from a metallic backing plate and at the same time accommodate the difference between the disparate coefficients of expansion of polyethylene and metal.  The composite (10) can be readily formed by placing a layer of uncured elastomer (13) on the prepared surface (11) of a metallic backing plate (12), spreading an ultra high molecular weight polyethylene powder (15) over the uncured elastomer and heating the thus assembled components, preferably under pressure, to cure the elastomer and melt the polyethylene powder.  When cooled, and the melted powder (15) coalesces into polyethylene layer (20), the resulting wear resistant composite (10) can be formed by conventional cold working processes into desired config-urations.

Abstract: ABSTRACT          An improved rotary device having means facilitating an increased power shaft diameter.  This means includes a pair of gear elements which are not related to the eccentricity of the device or to each other in the conventional manner known in the prior art. To compensate for these discrepancies in such relation-ships, additional gear rotational means is needed to control the rotation and revolution of the altered gear structure to compensate for the failure to maintain the heretofore required relationships with the eccentricity and with each other.  One embodiment of the invention utilizes a plurality of movement control discs to accomplish this gear compensation motion, while a second embodiment utilizes a plurality of compensation gears.

Abstract: ABSTRACT         Mining apparatus for sublevel caving is disclosed in which a single conveyor fed by a power loader is protected by a roof plate which extends substantially horizontally in contact with the roof of the bed.  A back plate is joined to the roof plate and also extends generally horizontally but with a space between it and the roof.  The back plate and roof plate are supported by props.  A door is provided in the back plate and this can be pivoted so that its edge adjacent the roof plate moves downwardly towards the conveyor thereby acting as a chute.  Pivotting is effected by hydraulic props attached to a base.  When the door is in the up position it engages the underside of an edge of the roof plate thereby assisting in supporting the roof plate.

Abstract: Abstract of the Disclosure A crop metering device for measuring by volume the clean crop yield of a combine harvester during harvesting, wherein a trap is located in the clean crop flow to build up a head of clean crop, and a paddle wheel or analogous device successively releases known volumes of crop at a rate which tends to maintain a predetermined head of crop above the trap.  A sensor determines when the head of crop has built up to the predetermined level, and initiates successive operations of the paddle wheel or analogous crop releasing device.   The volumes released are counted in relation to time or harvested area to determine yield.          A weighing device may be incorporated to enable an on-board computer to effect a volume to weight conversion.

Abstract: Self-Checking Safety Switch Control Circuit Abstract The present invention relates to a self-checking safety switch control circuit for a power combustion system.  The circuit comprises a safety switch, a combustion blower relay, a thermal pilot switch, and a fuel supply system.  The safety switch operates to detect flow through the combustion system. The safety switch either operates the pilot switch directly or operates the fuel supply system directly to shut down the system if no flow through the combustion system is detected. The circuit has a self-checking feature because  combustion cannot be initiated in a subsequent cycle of the system if the safety switch remains in the proven condition from the previous combustion cycle.
