Abstract: ABSTRACT OF THE DISCLOSURE      A pipe coupling made up of separably assembled plug and socket in which a latching piece is suspensibly held in the socket in latching engagement with the plug so that finger pressure on the latching piece drives it out of the latching engagement in order to enable easy disassembly of the pipe coupling.  A flow rate adjuster piece may be incorporated into the socket so that its axial turning changes the extent of recession of a valve off a valve seat in the plug so that the flow rate can be adjusted whilst retaining the assembled state of the pipe coupling.  Light, compact and cheap construc-tion is assured with simple operation and free flow rate adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for blending bulk particulate solids compri-ses a distribution chute bin, a cone section having outer and inner cones, and a flow pattern controller outlet device.  The solids may be recirculated from the outlet device to the chute bin for additional blending.  The chute bin prevents particle size segregation by causing mixing of coarse and fine particles.          The inner cone permits mass flow adjacent the outer cone, and also enforces the flow velocity profile imposed at the bottom of the cones to continue to the top of the inner cone.  The flow pattern controller is operable to shift between a blending mode resulting from the difference in the velocity profiles within and around the inner cone and a uniform flow mode useful when emptying the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE This invention provides a semiconductor memory device in which soft errors due to alpha particles are prevented. The device comprises a semiconductor substrate of one conductivity type; dynamic memory cells formed on the semiconductor substrate, each dynamic memory cell comprising one MOS transistor and one capacitor, the MOS transistor comprising a source diffusion region and a drain diffusion region, and the capacitor operatively forming a charge storage region. The device further includes a surface layer formed on the surface of the semiconductor substrate which has a conduction type opposite to the conduction type of the semiconductor substrate so that a potential barrier is formed between the semiconductor substrate and the surface layer. With the potential barrier, electrons derived from eleetron-hole pairs produced in the substrate by alpha particles are interrupted from entering into the charge storage region so that a soft error can be prevented.

Abstract: ABSTRACT A fluid dispensing valve is disclosed which has a valve casing, either (a) receivable within an outlet socket of a container for fluid, or (b) attached directly to said container.  The valve casing defines a conduit, one end of which is in communication with the interior of the container and the other end of which is in communication with an aperture constituting a valve seat.  A deformable, resilient diaphragm is accommodated within said conduit and has a centrally-disposed valve element thereon which is in sealing engagement with the valve seat when the valve is in the closed position, the diaphragm being provided with at least one opening therein.  The valve element is displaceable from said valve seat, against the biasing force of the resilient diaphragm, to thereby allow fluid to flow from the interior of the container into the conduit, through said at least one opening and out through the valve seat for discharge therefrom.

Abstract: MECHANISM FOR PURGING A PLURAL COMPONENT MIXING AND DISPENSING GUN A gun for mixing and dispensing plural component plastic materials, for example, polyurethane foam, is provided with a purging device operable independently of the foam mixing and dispensing mechanism.  The purging device comprises a rod, normally positioned rearwardly of the foam component inlet orifices and mixing chamber, the rod being selectively actuable independently of the foam mixing and dispensing operations, by a two way air cylinder controlled by the gun operator.  Purging elements, for example, compressible spheres or plugs of a plastic material such as styrene are fed under pressure to seat in a position rearwardly of the foam component inlet orifices and mixing chamber.  Upon selective actuation of the rod, one of the spheres is forced through the mixing chamber to purge any residual foam components by a scraping action.

Abstract: "TWO-PHASE FLOWMETER"                       ABSTRACT OF THE DISCLOSURE           The present invention provides a flowmeter for measuring pressure drops indicative of the flowrates of the individual phases in a gas and liquid containing two-phase stream.  Means are provided for creating and measuring a frictional pressure drop in the two-phase flow. Means are also provided for creating and measuring an acceleration pres-sure drop in the two-phase flow.  Mathematical models are known in two-phase theory for correlating these pressure drop measurements with the flowrates of the individual phases.  In a preferred mode of the invention the frictional pressure drop is measured across a twisted tape; the accelerational pressure drop is measured across a venturi downstream of the twisted tape, and the pressure drops are measured by pressure transducer means.  The meter also preferably provides means for measuring the static pressure of the two-phase flow.

Abstract: ABSTRACT OF THE DISCLOSURE:         A hopper discharge unit for attachment to the bottom of a hopper has upright side and sloping end walls all termin-ating in horizontally inwardly directed flanges defining between them a rectangular outlet opening, with the side walls extended rearwardly beyond the sloping rear end wall to form a support for a sliding gate, which is perforated along its sides to form racks engaged by pinions on a transverse operating shaft journaled in the side wall extensions above the gate.  To provide a tight seal the flange on the rear end wall is spaced above the side wall flanges to overlie the gate and a second longitudinal flange co-planar with the rear end wall flange is similarly spaced above the side wall flanges to overlie and cover the rack perforations in the gate when the gate is closed.         Lugs on the front wall force the forward edge of the plate down-wardly into sealing engagement with the flange on the front end wall when the gate is closed and a transverse rib on the top of the gate is adapted for wedging engagement with the rear of the rear end wall when the gate is fully closed.  A gravity-actuated hook-like latch is freely rotatably mounted at the center of the operating shaft and the rear end of the gate is provided with an upwardly sloping tab which co-operate with the latch to lock the gate automatically when the gate is in closed position.  For initiating opening movements of the gate, radial projections on the operating shaft engage the forward surfaces of upstanding blocks on the rear edge of the gate when opening movement of the shaft commences.  The operating shaft has on its projecting ends capstans formed with three rather than the usual four radial apertures to per-mit the insertion of a bar or lever at three angularly disposed positions with respect to the axis of the shaft, as compared with the two angularly disposed positions permitted with con-ventional four-hole capstans.

Abstract: Abstract of the Disclosure The combination of a dilute surfactant solution with an alkaline compound is effective in recovering oil from petroleum deposits after primary and secondary recovery operations have been completed.  The combination is injected into the petroleum bearing formation and as it travels through the structure oil is washed free of the rock and is recovered from a production well.  A preferred alkaline compound is sodium silicate.  The use of sodium silicate appears to maxi-mize and concentrate the recovery of the surfactant so that it can be recycled.
