Title: Electrically operated folding partition
Inventor: DIXON GUY E
IPC: E05F15/10
Filed: 1978-09-08
Granted: 1981-01-20
Abstract: ABSTRACT OF THE DISCLOSURE         An electrically operated folding partition including a plurality of pivotally interconnected panels movable from a straight line, flat, closed and locked position to an accordion folded stacked open position in which the control system will auto-matically move the partition panels from their closed position to their open position or from their open position to their closed position upon actuation of a suitable control switch or the like.          The panels are pivotally interconnected by hinge structures with the hinge axes being alternately disposed at or near opposite sur-faces of the partition to enable accordion folding movement of the panels. When moving the panels from their closed to their open posi-tion, the capability of the partition to be extended to a length greater than the length thereof when in fully closed flat position is used to "break" the panels form their closed flat position to a shallow accordion fold position with the hinge axes falling along a straight line at which point the movement of the endmost panel is reversed and inertial forces cause movement of the panels so the hinge axes cross over their straight line position.  When moving the panels from open position to closed position, the endmost panel is moved to a position with the hinge axes in alignment in which posi-tion the over-all length of the partition is greater than when the panels are in their flat straight line closed position with the endmost panel then being reversed so that inertia carries the hinge axes across their straight line position.

Abstract: ABSTRACT   A pedestal house with a cantilevered crossed truss construction forming the floor and wall supporting structure thereof has several pairs of crossed horizontally disposed truss members, each truss member has vertically spaced top and bottom cord members and interconnecting web members, one of each pair of truss members being of a greater height than the other so that one truss member of each pair passes through an opening in the other at right angles thereto.  Members are located longitudinally of said other truss member of each pair so as to increase the height thereof to that of the higher truss member of the pair.  This invention is distinguishable from others by reason of the pedestal house and the crossed truss members thereof forming a central area from which the ends of the truss members extend in cantilever form to form a wide stable support structure for the house on the pedestal.

Abstract: Abstract of the Disclosure A digital conference circuit for a digital telephone switching network is provided, connected between a receive TDM (time division multiplex) bus carrying PCM (pulse code modulation) words from the conferees to the conference circuit and a transmit TDM bus carrying PCM words from the conference circuit to the conferees. For a conference involving N conferees, N-1 shift registers serially interconnected are employed. As each PCM word, in a distinct time slot on the receive TDM bus, reaches the conference circuit it is entered into the first shift register in the series. The PCM words already stored in the shift registers are "shifted" along the series connection of shift registers by one register each time a new PCM word is entered in the first register, with the PCM word previously stored in the final shift register simply being "lost". Circuitry within the conference circuit monitors the binary value of the PCM words stored in the registers and during the time slot that one PCM word is  being received from a conferee, the PCM word previously stored in one of the N-1 registers that has the largest absolute binary value is output on the transmit TDM bus and it is received by the conferee who is "talking" during that same time slot (referenced to the conference circuit). With such a conference circuit a conferee never hears himself since the selection of whom he shall hear is made from the PCM words of all the other (i.e. N-1) conferees.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE         A parking brake control valve for a vehicle fluid pressure braking system is actuable by the vehicle p[eratpr to cpmtrp; communica-tion from a fluid pressure source to supply hold-off pressure to the vehicle parking brakes.  The parking brakes are of the spring applied, fluid pressure released type, in which the spring actuator automatically effects a mechanical brake operation when hold-off pressure drops below a predetermined level.  The parking brake control valve is responsive to supply pressure below a predetermined level to automatically vent the hold-off pressure from the parking brakes, but this predetermined low pressure is less than the value of the spring brake hold-off pressure below which the brakes are gradually applied or "drag".  The valve disclosed in the present application includes a check valve which isolates the hold-off pressure from supply pressure so that the hold-off pressure cannot vent in response to a decrease in the supply level to a sufficiently low value where the brakes may "drag".  However, when the supply pressure drops below the predetermined low pressure at which the spring brakes are to be applied, the parking brake control valve automatically vents the hold-off pressure to effect a spring brake application.  Consequently, the system disclosed in the present application prevents the spring brakes from "dragging", while retaining the safety feature of automatically applying the spring brakes when the supply pressure drops below the predetermined level.

Abstract: ABSTRACT OF THE DISCLOSURE          The  conformance  of  an enhanced oil  recovery process, including waterflood, surfactant or other chemical-ized water flood process, in a formation containing at least two strata or zones of varying permeability, the permeability of one zone being at lea t 50 percent greater than the permeability of the other zone, is improved by flooding until the higher permeability zone has been depleted, after which an aqueous fluid is injected into the high permeability zone, said fluid having relatively low viscosity at the time of injection and containing a blend of surface active agents which promote the formation of a coarse viscous emulsion in the flow channel of the  formation which reduces  the permeability of the high permeability zone.  After the permeability  of  the  first  zone  ha   been  reduced substantially, flooding may then be accomblished in the second zone which was originally not invaded by the injected oil  recovery  fluid.   The  surface  active  agents  are individually tailored and the ratio of dissimilar surfactants balanced to exhibit optimum viscous  emulsion formation properties.  The optimum emulsifying surfactant comprise mixture of an organic sulfonate such as petroleum sulfonate and a solubilizing co-surfactant such as  an alkyl or alkylarylpolyalkoxy alkylene sulfonate and/or a low molecular weight alcohol.                             -I-
