Abstract: SUPERCONDUCTING MEMORY ARRAY CONFIGURATIONS WHICH AVOID SPURIOUS HALF-SELECT CONDITION      IN UNSELECTED CELLS OF THE ARRAY    Abstract of the Disclosure A number of memory array configurations which avoid a spurious half-select condition in unselected cells of a superconducting memory array is disclosed.  The memory arrays incorporate memory cells which include at least single Josephson junction disposed in a superconducting loop wherein binary information is stored in the form of at least one circulating current.  For example, no circulating current can represent a binary zero, while a single circulating current can represent a binary one.  In another instance, counter-rotating circulating currents can represent a binary one and a binary zero.  The circulating current in combination with a half-select current, during writing of a selected memory cell, may, because of poor margins in adjacent memory cells, spuriously write information into an unselected memory cell when the half-select current is applied simultaneously to a number of memory cells which includes a selected memory cell.  By providing means for applying a control magnetic field to only the selected memory cell, spurious writing of an unselected memory cell is avoided.  This is accomplished in a number of embodiments by causing the application of the half-select current (which normally provides the control magnetic field to a memory cell) to divert a previously applied half-select or enabling current to the memory cell into another path so that the previously applied half-select or enabling current now acts as a control current for switching the storage gate of the selected memory cell. Diversion of the enabling current is, in turn, achieved by the switching of a serially disposed Josephson device which switches in response to the presence of two half-select currents in that device.  Any other similarly serially disposed device in an unselected memory cell en-counters only a single half-select current and, under such circumstances, cannot switch to control its associated storage gate.  Any other un-selected cell encounters, at most, a single half-select current.  In another arrangement, the initially applied half-select current enables a plurality of gates to which a second half select current can be applied.          When the second-half select current is applied, only that enabled gate associated with the line to which the second half-select current is applied switches, diverting the second half-select current into another path which controls the storage device of only the selected cell.

Abstract: ABSTRACT        The invention is comprehend with rigid thermoplastic sheet material of which the polymeric constituent is predominantly vinyl chloride polymer.        The sheet contains glass fibres lying in, or substantially in, the plane of the sheet the amount of glass fibre being in the range 3 to 30 per cent by weight of the material.        A particulate filler is also present in the sheet in an amount in the range 20 to 50 per cent by weight, the amount of the polymeric constituent of the sheet being 30 to 75 per cent by weight.        A sheet is conveniently made by building up successive very thin layers on a calender roll to ensure that the fibres are lying in the plane of the sheet.  Several such sheets are then laminated together under heat and pressure.        An extra reinforcing layer of a material such as a cloth, mat or scrim can be incorporated into the sheet, for example by including the reinforcing layer between laminations in the manufacture of the sheet.        The resultant rigid sheets are suitable for moulding. If desired decorative surface layers can be laminated onto the sheets and the sheets are then suitable for use, for instance, as wall panelling.

Abstract: ABSTRACT OF THE DISCLOSURE:         A portable air-operated apparatus for cleaning, flushing, and filling a liquid cooling system of an internal combustion engine.  The cooling system is cleaned by sequentially moving liquid in opposite directions in the cooling system.  The appara-tus also functions to pressure check the cooling system for leaks, to flush the cooling system of cleaning liquid and for-eign matter, and filling the cooling system with new coolant liquid.  The apparatus has an air-operated reciprocating piston pump assembly operable to agitate or sequentially move liquid in opposite directions and pump liquid into the cooling system.         The pump assembly delivers the liquid to a manifold connected to an input hose coupled to the liquid cooling system.  A con-trol valve connected to the manifold is operable to direct an external source of liquid under pressure to the manifold or connect a reservoir carried by the apparatus to the manifold.         The manifold has a check valve for controlling one-way forward flow of liquid from the pump to the input hose.  A by-pass hose connects the control valve and manifold to by-pass the check valve to allow reverse flow of liquid in the input hose back to the pump assembly so that the pump assembly will effect a sequential forward and reverse flow of liquid in the cooling system.  The control valve is operable to connect the reser-voir to the manifold so that the cooling system can be filled by the operation of the pump assembly with liquid stored in the reservoir.  A filter located in the reservoir filters liquid moved from the reservoir by the pump assembly to the cooling system.
