Abstract: "SEAT SUPPORT PROP"                 ABSTRACT OF THE DISCLOSURE         A seat support prop for use with a retractable seat assembly.  The prop is arranged to support the seat in a retracted position such as for providing access to the space normally below the seat.  The prop includes a latch pin re-ceived in a guide slot of a mounting element of the retractable seat assembly.  The slot includes an intermediate transfer portion obliquely related to a guide portion thereof in which the pin is received when the seat is in the seating position.          The slot is generally U-shaped with the transfer portion de-fining the bight thereof and extending at a substantial angle to the horizontal when the seat is in the seating position.          The guide portion extends at a small angle to the horizontal when the seat is in the seating position. The latching portion extends generally perpendicular to the transfer portion.  The prop structure requires that the seat assembly be moved beyond the retracted position both to effect the latching thereof and the release thereof in the selective positioning of the seat assembly.

Abstract: ABSTRACT OF THE DISCLOSURE         Scanning angle control for a linear array of spaced transducers in a pulse echo receiver is implemented by mixing the respective transducer outputs with progressively shifted output signals from a multi-stage, variable phase shifter fed by a local oscillator.  The additively combined mixer outputs thus contain frequency sum and difference components, which are extracted by low or high pass filters to implement scanning control on either side of a perpendicular to the array.  When a two dimensional array of transducers arranged in a row and column coordinate grid is employed, scanning in both azimuth and elevation may be implemented by coupling each column of trans-ducer mixers to the respective phase shifter stages through digital delay circuits arranged in rows and fed by a variable frequency clock pulse generator, whereby progressive delays are provided in the colunmar direction.

Abstract: ABSTRACT OF THE DISCLOSURE         A carbothermic process for the production of aluminum contaminated with no more than about 10 weight percent of aluminum carbide is disclosed which involves charging alumina values and carbon values into a furnace and subjecting only a minor portion of said charge at any given time to an open arc so as to heat the reagents to reaction temperature.  The various vapors which form pass through the charge where they undergo additional reaction.          The aluminum formed flows over the charge which is maintained at a temperature lower than reaction temperature, so as to obtain aluminum contaminated with no more than about 10 weight percent of aluminum carbide.

Abstract: DIFFERENTIAL AND PUSH-PULL CONTROL SYSTEM               Abstract A two cable differential and push-pull system uses both cables simultaneously to operate a controlled device.  The two cables are tensioned together or pushed together, or one cable is tensioned while the other is pushed, to operate a single device.  Controls which have used separate cables for separate functions use paired cables for the multiple functions, reducing stress on individual cables without increasing the number of cables in the installation. In the illustrated transmission control a differential motion, which includes pushing and pulling forces, is applied through the cables to select a rail.  A coincident pushing or pulling force is applied through both cables to shift the rail.

Abstract: ABSTRACT OF THE DISCLOSURE                  A single screw injection device or extruder se-quentially injects skin and foamed plastics melt into a mould to produce structural skin covered foam moulded parts free from swirl marks.  A single extrusion screw or plas-ticator selectively feeds, compresses and meters a plastics melt to a first injector for skin melt injection or to a gas injection well where it meters gas flow into the melt, mixes the gas and melt to form a foam and feeds the foam to a second injector for foam melt injection into the mould.      A valve controls the flow of the plastics melt and the foamed plastics melt to a single injection nozzle for dis-charge into the mould.  In sandwich moulding, a small amount of the unfoamed melt is first injected to form the skin for the moulded article and then the valve is shifted to connect the nozzle with the foamed melt from the screw whereupon the injector forces the foamed melt through the nozzle into the mould to overlie the skin melt.  The skin melt and the foamed melt are fed through the same nozzle and swirling in the mould is avoided.

Signals from the sensors are used to control the position of the piston in the cylinder and thereby vary the vertical separation between the compensated hook and the crane hook in relation to relative vertical movement between the crane boom and the landing platform.
