Abstract: IMPROVED MICROPHONE CONNECTOR                                  ABSTRACT The present invention relates to plug and socket connectors of the type used to couple cable conductors.  Although connectors are known to have both halves of their housings electrically connected to one another as well as the respective ground wires or sheaths related thereto, such connectors include a multiplicity of elements which in turn involves the disadvantages of complicated fabrication, assembly and sources of reliability problems.  The present invention overcomes these deficiencies by providing an improved cable connector having a grounding clip provided as part of a socket insert subassembly which projects outwardly of the plug assembly for reception and mounting in the receptacle assembly.  The grounding clip in part functions to insure that the plug and receptacle assembly housings are in grounded electrical connection with one another and further functions to elec-trically connect a ground wire means associated with the plug assembly to the housing thereof.  The clip also includes a spring element which biases a latch for the connector into a locked disposition.

Abstract: Abstract of the Disclosure The present invention is concerned with the production and use of water-insoluble particulate heteropolymers made by sequential emulsion polymerization in dispersed particles of which a "core" of a polymeric acid is at least partially encased in a "sheath" polymer that is permeable to a volatile base, such as ammonia or an organic amine, adapted to cause swelling of the core by neutralization.  The aqueous dispersion of the acid-containing core/sheath particles is useful in making water-base coating compositions wherein it may serve as the binder or as a part thereof.  In that use, the heteropolymer dispersion serves to provide desirable rheological control of the coating compositions and/or to serve as an opacifying agent when a volatile base is used to at least partially (to a pH of at least 6) neutralize the heteropolymer, microvoids being formed in cores of the swollen particles in the film during the drying thereof.  Thus, the heteropolymer dispersion can serve as a thickener, or part thereof and/or as an opacifying agent in coating compositions, such as water-base paints, as a supplement or replacement of part or all of the pigmentary material or extenders that would otherwise be used in such coating compositions.     For convenience of description herein, the terms "core", "sheath", and "core/sheath polymer" are frequently used to refer to the distinct functional compo-nents of the individual polymer particles of the essential "mode" of the heteropolymers of the present invention even though in actuality, the components of the polymer particles thereof may not have the precise arrangement implied by this terminology.

Abstract: ABSTRACT OF THE DISCLOSURE      A cache organization that enables many cache func-tions to overlap without extending line fetch or line castout time and without requiring a cache technology faster than the main storage transfer rate.  Main stor-age has a data bus-out and a data bus-in, each trans-ferring a double word (DW) in one cycle.  Both buses may transfer respective DWs in opposite directions in the same cycle.  The cache has a quadword (QW) write register and a QW read register, a QW being two SWs on a QW address boundary.  During a line fetch (LF) of 16 DWs, either the first pair of DWs, or the first DW of the LF is loaded into the QW write register, depending on whether the first DW is on a QW address boundary or not, i.e., whether the fetch request address bit 28 is even or odd, respectively.  Thereafter during the LF, the even and odd DWs are formed into QWs as received from the bus-out, and the QWs are written into the cache on alternate cycles, wherein no QW cache access occurs on the other alternate cycles for the LF.  Either 8 or 9 QWs occur for a LF depending on the first DW boundary alignment.  For a LF with 9 QWs, a write inhibit is needed for a non-data odd DW position in the last QW to avoid destroying the first DW written in the cache. If a line castout (CO) is required from the same or a different location in the cache, the CO can proceed during the alternate non-write cycles of any LF.  Any cache bypass to the processor during the LF can over-lap the LF and CO.  Any alternate cycles during any LF, which are not used for a CO or LF bypass, are available for processor request accesses of the cache for either DWs or QWs.

Abstract: ABSTRACT OF THE DISCLOSURE           A rotary drill bit for drilling a bore hole in the sur-face of the earth is provided in which the drill bit comprises a body having a duct therethrough for carrying drilling fluid.  A conical cutting head having an axis at an acute angle with respect to the axis of the drill bit is mounted in the cutting head.  An elongated nozzle is positioned at the end of the duct for injecting the drilling fluid into the bore hole.  The nozzle has an opening which opens into the bore hole wherein the longitudinal center line of the opening follows the locus of the mid-point between the side wall of the bore hole and the outermost circumference of the cutting head.  Drilling fluid injected through the nozzle removes detritus from between the teeth and the cutting head at the bottom of the bore hole.  The body of the drill bit has a first portion having a truncated conical surface with the axis of the truncated cone coinciding with the axis of the cutting head.  The surface of the truncated cone is tangent to the side surface of the bore hole at a line on the opposite side of the body from the nozzle.  This forms a passage between the surface of the truncated cone and the side surface of the bore hole for the upward flow of drilling fluid and detritus.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of and a protection relay for protecting electrical equipment.  The method includes dividing a prede-termined dividend value by a signal corresponding to the load current in the equipment to provide a quotient signal, and then linearly integrating the quotient signal.  When the integrated signal reaches a predetermined value, the equipment is tripped.  This provides an overload vs tripping time charac-teristic which is substantially linear.  The method further provides for sensing  whether the equipment is operating in a start up mode or in a normal running mode, and then automatically to select a less sensitive overload vs tripping time charac-teristic when the equipment operates in the start up mode and automatically to switch to a more sensitive characteristic when the equipment reverts to its normal running mode.

Abstract: ABSTRACT OF THE DISCLOSURE      In accordance with the present invention, in a pneumatic outlet a discharge tube is attached to sloped outlet walls having lips at their lower inner edges.  A rotatable control valve is located within the discharge tube.  The control valve is provided with a pattern of openings for metering flow of lading into the discharge tube and is arranged to reduce or eliminate pellets from becoming trapped in the valve opening.  Preferably the metering contour includes a pattern of sharp edges and taper-ed recesses.  The tapered recesses are arranged to guide pellets away from the valve opening.  The sharp edges will shear the remaining pellets which are trapped in the meter-ing opening, thus avoiding jamming the control tube.  The control valve further comprises arcuate segment of less than 180°.  With this arcuate segment any pellets trapped between the control valve and the wall of the tube tend to bend the control valve away from the lips and thus reduce any tendency for the control valve to become bound and unrotatble because the control valve abuts one of the lips.
