Abstract: Abstract of the Disclosure An apparatus is disclosed for use when dividing meat.  The apparatus includes a frame, a track for mounting the frame, a hook arrange-ment upon which meat to be divided is hung and which is arranged for move-ment on the track, and a hook-receiving device mounted on the frame for receiving the hook.  The hook-receiving device comprises three guide rails arranged to guide a stirrup-like part of the hook towards a predetermined position in the hook-receiving device.  Two of the guide rails diverge from the hook-receiving device towards the approaching hook so as to capture the stirrup-like portion laterally.  The third guide rail  is so designed and located in relation to the other guide rails and the hook that it prevents the hook from falling downwardly at least during the latter portion of the movement of the hook towards said predetermined position in the hook-receiv-ing device.

Abstract: Abstract of the Disclosure The present invention relates to a process for passivating the surfaces of semiconductor elements.  Silicon layers which are vapour-deposited on the surface of semiconductor elements have the effect of a permanent stability on the characteristic curves of the semiconductor element.  These silicon layers are annealed, in order to reduce the inverse currents.  This effects a permanent lowering of the inverse-current level.          This invention may be used on all semiconductor elements.

Abstract: AIRCRAFT BRAKE TORQUE LIMITER                   ABSTRACT OF THE DISCLOSURE         In an aircraft multiple disc brake assembly, an excessive total brake torque can be experienced during favorable, dry, conditions.         To limit the brake torque to a predetermined maximum, the plurality of conventional brake piston assemblies are modified to provide a pressure responsive surface area which is in an opposing relationship to the braking force.  When a predetermined amount of braking torque is experi-enced, conventional electronics employing strain gauge sensors control a solenoid valve to vent pressurized brake fluid to the opposing surface area thereby reducing the braking force and limiting the total braking torque experienced by the brake assembly to a predetermined maximum amount.  The brake pressure is not affected by this system.

Abstract: Abstract of the Disclosure: A blasting composition is disclosed which consists of at least 50% by weight of a solid particulate and undissolved nitrate oxidizer salt, usually ammonium nitrate prills (AN), and 10 to 40% by weight of a dense water-in-oil emulsion, mixed into the granular material to partially but not completely fill the interstices between the granule, giving the composition enough density that it will sink in water filled boreholes but not making it so dense that it will not detonate.  The composition contains up to 10% by weight of oil as a fuel, part of which may be mixed with the dry granules before the emulsion. a greasy water-repellant material, is mixed into the undissolved oxidizer.  The presence of air or gas in the interstices increases sensitivity of the composition to detonation while its density, greater than that of conventional dry ammonium nitrate-fuel mixtures (ANFO) provides it with greater blasting energy.

The first sheets of sets to be collated, numbering up to the desired number of sets in a job, are transported from an entry station to a unitary bin sheet receiving station via an arcuate sheet transport station having a feed path to and through the aforementioned unitary bin sheet receiving station.  These first sheets are stacked in the unitary bin sheet receiving station in an alternate offset fashion clearly demarcating the sets to be collated.  The second sheets of the aforementioned sets are then sequentially inserted in the same alternate offset fashion contiguous to the first sheets.  The method is repeated until all the sheets comprising a set have been inserted into all the sets.  The final result is collated, sorted and stacked sets readied for convenient removal from the unitary bin sheet receiving station by an operator.

Abstract: UNITED STATES PATENT APPLICATION               OF:     JACOB N. RUBIN and FREDERICK B. SEUFERT               FOR:    A PROCESS FOR CONVERTING   INTO NORMAL BUTANE                  ABSTRACT OF THE DISCLOSURE     A process for converting unsaturated C4 hydrocarbons into normal butane is provided.  Unsaturated C4 hydrocarbons are introduced into a hydrogenation zone wherein they are con-verted into a stream comprised of normal butane and isobutane. the normal butane and isobutane stream is discharged from the hydrogenation zone and directed into a separation zone wherein the normal butane is separated from the isobutane.  The normal butane is recovered from the separation zone and the isobutane is directed into an isomerization zone wherein a portion of the isobutane is converted into normal butane. The mixture of normal butane and isobutane formed in the isomerization zone is there-after returned to the separation zone for further recovery of additional amounts of normal butane.        In a preferred application of the process, the feed stream of unsaturated C4 hydrocarbons is obtained from the butene raffi-nate by-product of a butadiene recovery unit which derives feed from an ethylene production facility and the hydrogen introduced into the hydrogenation zone is obtained from the demethanization zone of the ethylene facility. The normal butane produced by the process then becomes one of the feedstocks of the ethylene produc-tion process to increase the yield of ethylene produced thereby.
