Abstract: ABSTRACT OF THE DISCLOSURE            A flow control valve assembly for closing an inlet into a housing through which powdery or granular material is flowing and for sealing said inlet once closed, the assembly comprising a closure member movable within the housing from an inoperative position in which the inlet is open into a normal operative position closing said inlet, during which movement a deformable sealing ring mounted in the housing to surround the inlet wipes over, to clean, the closing surface of the closure member and to make initial sealing contact with the closure member.          Inflation of the sealing ring against the closure member in its normal operative position then supplements the seal while, on subsequent pressurisation of the interior of the housing, the closure member is displaced bodily within the housing axially towards the inlet to make increased contact with, to supplement further the seal with, the sealing ring. 1.

Abstract: RCA 74,951 Abstract of the Disclosure A gain-controlled amplifier is provided in which emitter degeneration is varied without affecting the D.C. biasing of the amplifier.  An amplifying transistor is resistively coupled in a common emitter amplifier configuration with a fixed collector load resistor.  The emitter impedance of the amplifying transistor includes a controlled resistance device having a base electrode coupled to the emitter electrode of the amplifying transistor, an emitter electrode coupled to receive a variable gain controlling current and a collector electrode coupled to a point of reference potential.  At signal frequencies, the base-to-emitter junction of the device acts as a resistance which varies inversely with the flow of gain controlling current through the collector-to-emitter path of the device. Varying the resistance of the base-to-emitter junction of the device varies the emitter impedance and the degeneration of the amplifying transistor, which varies the gain of the amplifier.  The collector-to-emitter path of the device is separate from the transistor biasing circuitry, and hence modulation of the device will not affect the D.C. biasing of the amplifying transistor.  Under strong signal (maximum gain reduction) conditions, the controlled resistance device is turned off completely so that it will not introduce intermodulation distortion into the amplifier.  The fixed collector load resistor provides a constant, high output impedance, which reduces power dissipation and signal currents flowing in the amplifier power supply.

Abstract: VENT-SEALING, DOWN-LOCKED               PUMP  DISPENSER        Abstract of the Disclosure The plunger may be locked down after a full depression stroke so that the overall height of the pump assembly and the container with which it is associated can be significantly reduced.  A special valve component loosely encircling the plunger and slidable with friction along the interior surface of the barrel is initially positioned during factory assembly in a closed position covering vents in the sidewall of the barrel, thereby blocking the undesirable ingress of liquid into the barrel above the piston should the container be laid on its side during shipment or other handling.  Upon the first unlocking upstroke of the plunger to its extended position, a shoulder on the plunger lifts the valve to an open position so the vents can function properly to introduce ambient air into the container re-placing pumped-out product.  The valve remains stored in its open position until such time as the plunger is once again locked down beyond the limit of its normal depression stroke, this action causing a second shoulder on the plunger to push the valve back down to its closed position.

Abstract: C 685 (R) ABSTRACT OF THE DISCLOSURE            The premature release of chlorine from chlorine-releasing bleaching agents in a particulate detergent composition, caused by the action on such a bleaching agent by some other component in the detergent composition, is prevented by compacting and granulating a mixture of said other component, preferably with additional constituents which do not have the premature chlorine-releasing effect, and then mixing those granules with the chlorine-releasing bleaching agent and other appropriate detergent constituents. The resulting novel detergent composition is a mixture of the granules thus produced with particles of the said other appropriate detergent constituents.    As desired the mixture can be shaped into pellets, tablets or bars.

The construc-tion includes at least a pair of juxtaposed hyperbolic paraboloid units, each unit comprising four quadrants, each quadrant having a pair of spaced, stiffened, horizontal edges and a pair of spaced, stiffened, sloping edges, the sloping edges sloping downwardly from an upper level to a lower level.  Two sloping edges of the first unit are contiguous to two sloping edges of the second unit and the other sloping edges of the units are non-contiguous.  The stiffened horizontal edges all lay in in a top, horizontal plane.  The juxtaposed units are joined together at respective contiguous sloping edges thereof to form a multiple unit roof span that includes both horizontally extending edges and sloping edges.          A plurality of vertical members support the roof span at the lower ends of only the non-contiguous sloping edges.  Finally first horizontally disposed and tensioned members connect the lower ends of the sloping edges that are unsupported by vertical members with the lower ends of sloping edges that are supported by vertical members.  The first tensioned members all lie in a lower horizontal plane.  In this way a free span roof construction is provided.  In other words, this construc-tion  can be employed to form a large roof span without using interior vertical support members.
