Abstract: Docket FK 1625 ABSTRACT     An apparatus for crushing mine ore or hard rock primarily for initial reduction for transport of the material for further processing which is characterized by an extremely low vertical profile relative to its size and capacity.  The crushing jaws which form the crushing chamber are uniquely arranged in an inclined relationship with the lower jaw mounted for eccentric movement relative to the upper jaw which is stationary to provide efficient crushing action and efficient movement of the crushed material through the chamber while also permitting the associated inlet feed apparatus to be disposed at a low attitude.  Means are included to provide for varying the size of the discharge opening and for varying the action of the moveable crushing jaw to permit greater versatility in the proper processing of a given material.

Abstract: LOAD MEASUREMENT DEVICE            ABSTRACT OF THE DISCLOSURE     Apparatus for sensing and measuring the torque output of a rotary device such as a gear reduction box by inserting an especially machined or configured adaptor between the shaft bearing and the bearing mounting housing.  This adaptor transducer will have strain gages mounted on it in spaced relationship so that the tangential force from the gears reacting on a shaft will produce a deflection in the adaptor transducer which will be detected by the strain gages.  The strain gage signal then will be sensed, ampli-fied and can be recorded on an analog read out type meter or monitored continuously on a pen-type recorder or other conventional instruments.  The strain gages can be calibrated so the output of the recorder will convert the signal into a direct reading of the torque output transmitted through the gear reduction box.

Abstract: 116?5 ABSTRACT OF THE DISCLOSURE             A container for the transport, storage and disposal of radioactive wastes or other materials, such as irradiated fuel elements of a nuclear reactor, capable of neutron emission, which comprises a cast receptacle, e.g. of cast iron, a cover and, in passages spaced apart in the cast wall of the vessel, a neutron moderating or absorbing material.  According to the invention, the passages are of circular cross section with a spacing at least equal to twice the diameter, and the total cross-sectional area of the passages in any plane transversely through the vessel corresponds to the cross section in the same plane of a continuous theoretical layer disposed along the periphery of a vessel of corresponding thickness and size or is greater than  the area of the theoretical layer in this plane in so far as neutron absorption or moderation effect is concerned. The moderator passages thus provide a total volume which can cor-respond to the volume of the theoretical layer applied extern-ally of the wall of the vessel and for a given moderator material will have the same moderation or absorption effect.

Abstract: BULKHEAD DOOR LOCKING ARRANGEMENT   ABSTRACT OF THE DISCLOSURE         A locking arrangement for a bulkhead door in a freight transport vehicle in which locking plates are selectively positioned along tracks on each side of the vehicle floor, and are engaged by locking pins in the bulkhead door.  A locking track is mounted in the trans-port vehicle floor along each side thereof, and extends along a substantial portion of the length of the vehicle.          Each track consists of an elongated, rectangularly-shaped steel plate positioned to extend along a longitudinal side of the vehicle, and has a number of vertically-extending holes formed therein and spaced along its length.  Each locking plate has a relatively short length in comparison to a locking track, and has several posts extending vertically downwardly from its bottom to engage the holes in a locking track.  Each locking plate has a number of vertically-extending holes spaced along its length, with the number of holes per unit length in each plate being substantially greater than the number of holes per unit length in each locking track.  The arrangement allows a locking plate to be selectively positioned along the length of a locking track at a location where a bulkhead door is to be placed.          The bulkhead door is then vertically positioned in the vehicle, and vertically extensible pins on each side of the bulkhead door engage one of the holes in the locking plates on each side of the transport vehicle.

Abstract: 211-P-US?2?91 PROCESS FOR PRODUCING HYDROGEN FROM SYNTHESIS GAS CONTAINING COS ABSTRACT OF THE INVENTION Process for treating synthesis gas to recover a purified essentially sulfur-free hydrogen-rich stream. The novel sequence of operations employed comprises initially removing from the feed gas, such as from a synthesis gas derived from partial oxidation of coal or oil, the bulk of contained H2S and a substantial part of the contained COS, by physical absorption in a suitable solvent. The gas from the initial absorption is then subjected to water-gas shift reaction over a sulfur-resistant shift catalyst under conditions such that in addition to the conversion of CO to CO2 most of the contained COS is hydrolyzed to H2S. The gaseous shift product is then subjected to a second treatment with suitable solvent to remove by physical absorption essentially all of the remaining sulfur, which is then present as H2S. The thus desul-furized gas mixture is then sent to a CO2 absorber, from which a H2-rich gas effluent is withdrawn. The H2S bearing solvent from the second treatment is used in the initial absorbtion. H2S is stripped from the initial rich absorption bottoms liquid to recover a Claus gas effluent of high H2S content, while the stripped liquid bottoms are recycled for further use in the process. .

Abstract: ABSTRACT OF THE DISCLOSURE       A logical circuit which is capable of serving not only as a shift register but also as counter comprises a cascade-connection of flip-flops of the same number as bits required.  The flip-flops are each provided in its input part with a logical gate group composed of gates which are opened and closed by a shift signal and a count signal.  The logical circuit does not require to provide a flip-flop group in each of a shift register part and a counter part as is needed in a conventional shift register/counter circuit.  The logical circuit is capable of performing an independent operation of a shift register, an independent operation of a counter and a compound operation of inputting data in serial for initializa-tion and outputting counted data in serial.  With the logical circuit of the present invention, the number of gates used is greatly reduced as compared with the prior art shift register/ counter circuit; accordingly, the circuit of the present inven-tion is of particular utility when formed as a large scale integrated circuit.
