Abstract: ABSTRACT OF THE DISCLOSURE         A process for separating relatively fine solid particles differing in size and specific gravity by the use of a heavy medium which includes magnetizable particles where a mixture containing the fine particles to be recovered and the heavy medium are fed under pressure to a specific gravity separating cyclone which divides the mixture into a ?    tively fine specifically light fraction from which the magnetizable particles of the heavy medium are subsequently removed for re-use in the system while the diluted flow of the fine specifically light particles to be recovered is fed to a thickening cyclone which separates the bulk of the particles from the carrying liquid; the fine particles are then recovered from a filter screen while a portion of the liquid is further used in the process to facilitated recovery of the magnetic particles from the specifically heavy fraction derived from the cyclone.

Abstract: ABSTRACT OF THE DISCLOSURE      A tapered, felt-covered tension drum is rotatably supported across a path along which a series of warp yarns are fed to a shedding mechanism of a loom.  The warp yarns are made to pass over the tension drum by a pair of guide rolls disposed parallel to the axis of the tension drum.           A brake band affixed at one end to a frame and carrying a weight on the other end is wrapped around the tension drum for application of a constant braking force thereto.  As the warp yarns are forcibly pulled past the tension drum, the latter is frictionally rotated against the constant braking force to impart progressively varying degrees of tension to the successive individual warp yarns.  Thus tensioned, the warp yarns are interlaced with the filling to provide a continuous length of stringer tape which is curved in its own plane.

Abstract: PHASE-LOCKED LOOP LASER GYROSCOPE SYSTEM                  Abstract A very high resolution laser gyroscope system having a phased-locked loop operatively coupled to one or more frequency difference outputs from a laser gyroscope cavity.  Waves of at least four frequencies propagate around the gyroscope cavity, with output signals being formed having a frequency equal to the difference between the frequencies of wave  pairs.  In one set of embodiments of the invention, the frequency difference signal for one wave pair is phase-locked to an external reference source.  A signal applied to a Faraday rotator bias coil provides the frequency shifting of the wave pairs necessary to achieve phase lock.  The amplitude of the signal applied to the Faraday bias coil provides a highly precise measure of the rate of rotation.  In another set of embodiments of the invention, one or more of the wave pair frequency difference signals are coupled as inputs to an external phase-locked loop in which a voltage controlled oscillator-is followed by a frequency divider of the feedback circuit.  In these embodiments, the output of the voltage controlled oscillator provides an output signal which has a frequency in proportion to but many times higher than the frequencies of the wave pair difference signals   In still further embodiments of the invention, the two phase-locked loop techniques may be combined.  In all of the disclosed systems, the quantization error normally associated with laser gyroscope output signals is substantially reduced.

Abstract: ABSTRACT OF THE DISCLOSURE:    A box setting tool includes a flat, relatively thin box holding blade adapted to be positioned against a flat edge wall of an electrical junction box or switch box.  Two box holding fingers are integral with the box holding blade and extend generally parallel to the box holding blade.  They are curved so as to permit a flat edge wall of a junction box to be forced between them and the holding blade thus to holdingly position the junction box with respect to the tool.  A trans-versely extending box positioning bar is fixedly positioned between the holding blade and the holding fingers and is provided with a box wall positioning edge situated to receive the forward flat face of the junction box edge wall.  A stud contact blade is fixedly mounted with respect to the holding blade on a side thereof opposite the positioning bar and is provided with a stud contacting face extending outwardly from the holding blade at right angles to it.  The distance along the box holding blade from the plane of the stud contacting face of the stud contact blade to the box wall positioning edge of the box positioning bar is selected to be commensurate with the thickness of the plasterboard which will later be nailed on the wall stud face so that after the junction box is installed with the tool in contact with the wall stud and holding junction box, the forward edge of the junction box will be situated flush with the surface of the plasterboard.

Abstract: "SEALING ASSEMBLY".                        ABSTRACT.    The invention is concerned with sealing assemblies of the type comprising two members which are movable relative to one another and in which one of the members has a cylindrical surface and the other member contains an annular groove, a sealing ring being located in the annular groove and engaging the cylindrical surface. A problem with such sealing assemblies is that, when they are subjected to substantial pressure differentials, unacceptably high leakage of gas or liquid past the seal can occur. Such leakage is reduced in a sealing assembly in accordance with the invention in that one (22) of the radially extending walls of the sealing ring (20) includes a chamfered portion (24) such that the axial dimension of the radially inner surface of the sealing ring (20) is less than the axial dimension of the radially outer surface of the sealing ring, the annular groove including a complementary shaped wedging surface (26) for co-operation with the chamfered surface (24) of the sealing ring (20).

Abstract: BI-DIRECTIONAL CATV DATA TRANSMISSION AND CONTROL SYSTEM            Abstract of the Invention A bi-directional data transmission and control system utilizing a central processing unit and a multiplicity of remote subscribers.  Each subscriber is provided with a terminal coupled with the central processing unit by a suit-able medium such as a CATV channel.  Each terminal is provided with a demarcation plane separating common circuitry from a number of specialty modules and a common bus therebetween for circuitry simplification, application expandability and individual tailoring.  The data transmission scheme efficiently utilizes the frequency spectrum and enhances polling frequency by permitting selective polling of any given specialty module or subscriber at any given time and by permitting simultaneous polling of every subscriber for service calls, thereafter locating the caller with minimal polling.  Data transmission protocol is expandable or contractable for each terminal independently of others and permits data transmission between any two points in the system.  The system is zoned such that failure of one zone does not disable the entire system.
