Abstract: MARINE JET DRIVE SHIFT CONTROL APPARATUS                  Abstract of the Disclosure A marine jet drive unit includes a continuously running pump.  A reversing gate is positioned partially or wholly within the forward jet to establish a corresponding reverse jet.  For neutral drive, the gate is positioned such that the reverse jet just balances the forward jet.  A remote shift control unit includes a detent means for locating and holding a rotatable shift lever in neutral.  The detent means includes a pair of detent pins carried by a plate which is connected to a support wall by a slot and bolt lost motion connection.  The pins are located to opposite sides of the lever and the connection permits angular adjustment about the pivot axis of the lever.  The plate supports the detent pin in alignment with a circular outer  periphery of the lever plate having oppositely located radial detent grooves.  The lever  is connected by a push-pull cable to the gate.  The precise neutral posi-tion of the lever may vary for different drive units.  The lever and gate are positioned to establish neutral setting for the particular engine-pump unit.  The detent plate is then adjusted to align the detent pins with the grooves and the bolts drawn up to lock the detent plate in a fixed neutral position.

Abstract: SPONGE IRON PRODUCTION PROCESS                ABSTRACT OF THE DISCLOSURE         This invention relates to sponge iron production. Iron oxide is reduced by reducer gas containing, for example, hydrogen and carbon monoxide, in a reaction zone to give the sponge iron product and a gaseous product.  The latter is treated to reduce the quantity of oxidising gases, e.g. water vapour and carbon dioxide, therein and the thus treated gaseous product is recycled to the reaction zone.  In this way the gases passing through the reaction zone can have a lower content of water vapour and carbon dioxide than the initial reducer gas promoting the production of sponge iron.

Abstract: SHARPENER FOR COMMODITY SLICING MACHINE                Abstract of the Disclosure The guard cover for a commodity slicing machine sharpener extends over and protects the otherwise exposed knife edge at the knife sharpening area.  The guard protects the knife edge at all times regardless of whether the sharpener is in the sharpening position, storage position, or is being moved between these positions.  The sharpener employs a non-rotatable honing stone which seeks proper honing relationship with the knife upon coming into contact therewith.  A latch holds the sharpener when in the sharpening position and pre-vents it from being returned to the storage position until released.  The latch release is position dependent so that the operator's hand and fingers should be in a certain pre-determined position on the sharpener housing, away from the knife edge, to operate the latch release.

Abstract: ABSTRACT OF THE DISCLOSURE           A current differential fault detection circuit is used with a plurality of main current transformers respectively coupled to a plurality of separate conductors through which current flows into and out of a sectionalized portion of an a-c electric power system.  The secondary windings of the main current transformers are connected in parallel with one another.  A normally non-conducting solid state a-c switch is connected in series with the primary winding of an auxiliary transformer and the series combination is connected in parallel with the secondary windings of the main current transformers. When the secondary winding voltage exceeds a predetermined level the a-c switch is triggered into conduction thereby allowing the fault current to flow through the primary winding of the auxiliary transformer.  Circuitry connected to the secondary winding of the auxiliary transformer senses the fault current level.

Abstract: A METHOD FOR FORMING INTEGRATED CIRCUIT REGIONS          DEFINED BY RECESSED DIELECTRIC ISOLATION                 ABSTRACT OF THE DISCLOSURE    In the fabrication of integrated circuits, a method is provided for forming dielectrically isolated regions in a silicon substrate comprising initially introducing conductivity-determining impurities into the substrate to form at least one region of one-type conductivity at the surface of said substrate.  Then, a mask comprising a com-posite of a bottom layer of silicon dioxide and a top layer of silicon nitride is formed over at least a portion of the surface of said introduced regions.  The substrate is then subsequently thermally oxidized to an extent sufficient to form regions of recessed silicon dioxide abutting and thus laterally defining said region of one-type conductivity.          In this manner, it is ensured that the recessed silicon dioxide will abut introduced region irrespective of the extent of the "bird's beak" normally associated with thermal oxidation utilizing silicon dioxide-silicon nitride masking.

Abstract: Abstract of the Disclosure A connector for high tensile load attachment to an elongated rod, such as a resin bonded, glass reinforced rod, includes a high strength, elongated, metal cylindrical re-tainer having an internal shoulder formed at one longitudinal end and a plurality of outer peripheral threads formed at the other longitudinal and for the treaded attachment of a hook or other load bearing device. The connector further includes a plurality of metal collets or rings, whose inner peripheral profile configurations are that of a pair of truncated cones within  the retainer. The slopes of the cones of the collets received within the retainer are independently, variably preselectable to achieve optimum results. The junctions or edges defining the intersections of the bases of the cones are rounded off to avoid excessive stresses being transmitted to the rod. In mounting the connector onto an end of an elongated number of the collets, depending upon the tensile load anticipated, are serially placed within the retainer end about against the shoulder of the retainer. An elasto-meric O-ring seal is positioned securely about the rod and beneath the underside of the retaining cylinder. An organic potting compound, for example an epoxy resin, is poured into the space between the rod and the collets and is held therein by the O-ring seal. After the potting compound has set, the O-ring seal is removed and a suitable load bearing de-vice or attachment may be threaded onto the threaded end of the retainer.

Abstract: ABSTRACT OF THE DISCLOSURE         A flushing air valve for selectively subjecting a selected filter member or members to a flushing air impact to remove a dust deposit on the member.  The valve member of the type of an axially movable plate closes a conduit between a flushing air chamber and a clean air plenum ad-jacent the respective filter disposed in a cleaning compart-ment of a dust removing filter apparatus.  The opening and closing of the valve is governed by opening or closing of a pilot exhaust valve.  As the pilot valve opens, the flush-ing air pressure acting on the side of the valve member fac-ing the exhaust is reduced so that the flushing air pressure acting on the opposite face of the valve member opens the valve.  Means providing an air cushion for decelerating the opening stroke of the valve member is provided to prevent the valve member from striking against the chamber wall, to thus reduce the noise of operation of the valve.  The required pres-sure of the flushing air is reduced as the operation is govern-ed solely by opening or closing the pilot valve, without any further requirements for the operation of the pilot valve, such as re-directing the flow of the flushing air etc.

Abstract: HIGH SPEED LABELING MACHINE                Abstract of the Disclosure A drum continuously rotating on a vertical axis carries at least two pairs of label transfer members spaced cir-cumferentially around its axis and rotatably connected to the drum on vertical axes.  One of the transfer members in each pair is a pick-up member and the other a delivery member, with the pick-up members alternating with the delivery members.  The pick-up members are continuously rotated on their axes in one direction while the delivery members are rotated in the opposite direction at the same speed. Each of the transfer members has a label-contact surface provided with a vertical row of air inlets, the contact surface of each pick-up member facing away from the axis of the drum when that member is in pick-up posi-tion at the label magazine, at which time suction is applied to the air inlets to withdraw a label from the magazine.  The suc-tion is subsequently released while suction is applied to the air inlets in the delivery member of the same pair when their contact faces are directly opposed to each other, whereby to transfer the label from the pick-up member to the delivery mem-ber.  The contact surface of the delivery member faces away from the axis of the drum when that member is in delivery position beside the label-applying apparatus.  The suction at the deliv-ery member is released after the label has been delivered to the label-applying apparatus.  The rotations of the drum and delivery members combine to move the contact surface of the delivery member that is in delivery position forward at the same speed as the adjoining surface of the label-applying apparatus.

Abstract: TASK MANAGEMENT APPARATUS            ABSTRACT    A data processing system is described which has multi-ple sets of registers each of which is capable of autono-mously controlling a common storage and common arithmetic and logic control circuits to execute respective tasks of a program.  Level status blocks (LSBs), each assigned to a respective task, are held in main storage; and each con-tains such address and status data as is required for task execution in a controlled environment.  Apparatus, including a current level register, a selected level register, a pending level register and an in-process bit latch, is con-trolled during the execution of a load level status block (LLSB) instruction to transfer the LSB of a selected task from storage to the selected register set, determine the status of the in-process bit of the selected task LSB and the relative priority levels of the current and selected tasks, and pursuant to said two determinations handle the task dispatching, preemption, enqueuing, dequeuing functions without the need for further software processing.  At the completion of the LLSB instruction execution, either the current task execution is continued, the selected task is initiated, a pending task is initiated or a system wait state is entered.  A store level status block (STLSB) instruction is executed to copy the LSB of a selected task from the register set to storage. Hardware backup regis-ters are provided to hold certain updated status of the current register set to improved performance.  These backup registers are changed during the LLSB execution if task switching occurs and are restored to the current register set during STLSB execution.
