Abstract: CAM FOR CABINET LOCKING SYSTEM                   ABSTRACT OF THE DISCLOSURE         A gang locking system for use in furniture cabinets having a plurality of doors or drawers comprises a lock tube which rotates to move a lock bar from a disengaged or open position to an engaged or locked position.  Rotation of the lock tube is effected by a lock cam attached to a lock cylinder.  The lock cam is a generally rod shaped member having two offsets to constitute a "Z" or zig-zag shape and projects through a pair of slots in the lock tube.  The slots in the lock tube have a width only slightly greater than the diameter of the rod-like cam so as to reduce any slack or "play" between the lock cam and the lock tube.

Abstract: Abstract Waterproof filling medium, used in telecommunication cables with cellular insulation of polyethylene or polypropylene, is based on a mineral oil (with or without a gelling agent such as microcrystalline wax) and includes two non-polar additives.  The first is soluble and of low enough molecular weight to reduce significantly the osmotic pressure of the base, but does not diffuse into the insulation below 80 °C; and the second is polymeric and of high enough molecular weight to increase the resistance to flow to obtain the required non-draining property.  Filling of cells in the insulation is inhibited.

Abstract: ABSTRACT                  VISUAL DISPLAY INPUT DEVICE    An input device for a computer controlled visual display enables an operator to instruct the shift of a display element in a chosen direction by hand movement of the input device sensor in an analogous direction over a plane surface.  The sensor includes a conventional piezoelectric audio pick-up which produces a succession of unidirectional pulses when the stylus is drawn across a microscopically textured surface such as a sheet of paper, the polarity of the pulses being indicative of the direction of motion along a selected axis.  A second pick-up is arranged to give a maximum response to motion along an orthogonal axis and for the component of motion on each axis a bi-directional pulse counter enables the direction of motion to be determined by a comparison of the counts held in successive time intervals.

Abstract: ABSTRACT OF THE DISCLOSURE          A self locking threaded fastener is disclosed wherein the self locking system includes a plurality of bearing surfaces contained within a bearing plane and positioned in an annulus around the thread means.   Extending inwardly from each bearing surface is a ramp surface which is inclined inwardly and back from the bearing plane.  An axially extending shoulder joins one edge of each ramp surface.  When the fastener is tightened against a mating part to clamp such part, the engagement causes sufficient pressure to displace material of the mating part by cold flow or other type of displacement into the recesses between the ramp surfaces and shoulders. Continued tightening rotation does not encounter excessive torque since the ramp surfaces provide a camming action but loosening rotation is resisted by the interference between the displaced material and the shoulders.  As displacement occurs, additional portions of the ramp surface engages displaced material to increase the effective bearing area and locking interference and provide a self limiting action with respect to the extent the fastener embeds in the mating surface.

Abstract: Abstract of the Disclosure A device with an electromagnetic clutch includes a tubular member of steel which is secured to, and canti-levered by, a flange member secured to a housing of the device.  A pulley having magnetic pole faces is rotatably mounted on the tubular member by one or more bearings.  A drive shaft of the device extends out of the housing and through the tubular member, and supports a magnetic armature on the extended end.  An electromagnet associating with the pulley is fixedly supported on the flange member, to supply magnetic attraction force for attracting the armature plate to the pulley.  In the arrangement, since the wall thickness of the tubular member is made thin, the outer diameter of the clutch can be reduced without degrading the transmission of rotational force.  And a shaft seal assembly can be mounted on the drive shaft within the tubular member.          Furthermore, the inner ring of the bearing is held between the flange member and a retainer ring fitted onto the tubular member to be prevented from axial movement.          In order to prevent the inner ring from rotating, the inner ring is locked to the flange member by connection of projections and mating depressions formed thereto.          Thus, the assembling operation of the electromagnetic clutch is simplified.

Abstract: A B S T R A C T     A device for automatically welding a tube onto a pipe of larger diameter is the subject of the present invention.          Tack welding is achieved by two welding torches located on opposite sides of the tube and spaced apart longitudinally a distance equal to the distance desired between tack welds.  The entire torch assembly is mounted on a movable carriage that is motor driven.  A frictional spool wheel engages the tube to drive the carriage while also serving as a guide wheel.  Two cam wheels are also driven by the same motor that drives the carriage.  One cam wheel controls operation of the welding torches on an intermittent basis.  The second cam wheel controls the drive motor so that the latter is operated at a first speed during welding and a faster speed when welding is interrupted.  This allows the device to traverse a given distance in less than half the time that would be required if the slower welding speed were maintained throughout the entire length of the tube.

Abstract: FLUIDIC OSCILLATOR WITH RESONANT INERTANCE AND DYNAMIC COMPLIANCE CIRCUIT     ABSTRACT           The fluidic oscillator consists of a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance.          The inertance is a conduit interconnecting two locations of a chamber on each side of a working fluid jet issuing into one end of the chamber, the inertance conduit serving to transfer working fluid between the two locations.  Through one or more output orifices located approximately at the opposite end of the chamber, the fluid exits from a chamber exit region which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid.  The flow pattern in the chamber and particularly the vortex in the-chamber exit region provide flow aspiration on one side and surplus of flow on the opposite side of the chamber, which effects accelerate and re-spectively decelerate the fluid in the inertance conduit such as to cause reversal of the vortex after a time delay given by the inertance.  The vortex in the chamber exit region will thus cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream our spray pattern whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector as well as the dynamic pressure component, both directed radially from the vortex.  By changing these para-meters by suitable design measures and operating conditions and by appropriately configuring the oscillator, sweep angle, oscil-lation frequency, distribution, outflow velocity, break up into droplets, etc. can be readily controlled over large ranges.

Abstract: PHF 79050                10                   19.3.80 ABSTRACT: Method of testing an integrated circuit.     In order to set the circuit to be tested to a test mode, at least one output is led out via an output stage, and the input and output of said output stage in-ternally leads to an exclusive-OR gate. As long as the output has a comparatively high ohmic termination, as is the case during the normal mode of operation, the ex-clusive-OR gate will carry the same signal for both sig-nal conditions of the output. For the purpose of testing a complementary pulse pattern is applied to the output, so that the exclusive OR gate supplies an opposite sig-nal, which establishes the test mode. The output of the exclusive-OR gate may lead to a bistable multivibrator, so that for establishing the test mode only a single complementary signal is required.
