Abstract: Abstract of the Disclosure An apparatus for electrochemical purific-ation of contaminated liquids comprises a settling chamber having outlet pipes for discharging purified liquid and waste and communicating with an electro-coagulation chamber arranged in said settling chamber and comprising in its bottom portion a system of soluble electrodes.  An inlet pipe is provided for feeding contaminated liquid into the electrocoagulation chamber above the soluble electrodes.  An inlet pipe is also provided for feeding an electrolyte into the electrocoagulation chamber and a device is provided for removing foam from the apparatus as liquid is discharged into the coagulation chamber into the settl-ing chamber.  The foam-removing device has a pipeline for transferring foam outside the settling chamber and is provided with a bell shaped opening at one end thereof and having the other end communicating with the outlet pipe for discharging waste.  The pipeline for transferring foam is rotatable in a hori-zontal plane, and the bell shaped opening is arranged substantially above the settling chamber.  This pipeline is provided with an air injector for drawing foam into the bell shaped opening and transferring it through the pipeline to the open end thereof.  The invention makes it possible to enhance the efficiency of the apparatus and to improve the stability of the pur-ification process.

Abstract: ABSTRACT OF THE DISCLOSURE         A reproducing stylus traces a track of a recording medium, in which track an information signal is recorded as variations of geometrical shape, and reproduces as variations in capacitance the information signal thus recorded.  The reproducing stylus comprises a reproducing stylus main structure having a tip part with a flat sliding contact face for slidingly contacting a plurality  of tracks of the recording medium at a time, and an electrode secured to the reproducing stylus main structure at the tip part thereof and adapted to trace one track and reproduce the information signal as the variations in capacitance in accordance with the variations in geometrical shape.  The electrode has over a specific distance over the tip part of the stylus main structure from the extreme tip thereof,a constant width in the width direction of the track which is less than the width of the track.  The extreme tip of the electrode has a flat or linear tip end contacting the track.

Abstract: ABSTRACT            A disk brake rotor includes material or mass, preferably in the form of metal generally integrally cast with and disposed generally adjacent the outer periphery of the rotor which thermally balances the heat sink and inherent heat sinking function of the central mounting section portion of the disk rotor.  In a vented disk brake rotor, this balancing mass may be disposed in the wall of the rotor most proximate the mounting section by proportioning the thickness of the wall at a given point in relation to the radial distance from the center of the rotor.  In a solid disk brake rotor, thermal balancing mass may be disposed adjacent the periphery of the rotor beyond the wall areas of the rotor swept by the disk brake pads.  The invention may also be practiced by providing an unswept area of a rotor sidewall proximate its outer periphery by reducing the radial width of a brake pad thereby providing a region which functions as a heat sink to compensate for the heat sinking function of the mounting section rather than a source of frictional heat.

Abstract: CMOS OPERATIONAL AMPLIFIER             WITH REDUCED POWER DISSIPATION                          Yusuf A. Haque Abstract of the Disclosure An operational amplifier comprised of MOSFET elements is disclosed which provides for a variable drive for an output stage that results in lower power dissipation and increased gain factor over comparable circuits using constant bias drive for the output stage.  A bias section comprised of complementary MOS elements is connected to a single MOSFET that furnishes constant current to the signal input section of a differential amplifier section. The output of this differential amplifier is furnished by one path directly to one complementary MOSFET element of a high impedance output stage and by another path to a level shift section which provides an output to a second comple-mentary MOSFET element of the output stage.  Thus, the circuit functions under class A-B operation at low power dissipation and provides high open loop gain.  Additional embodiments of the invention utilize three MOSFET elements in the level shift section or an additional output stage having an NPN transistor in combination with an N-channel MOSFET.

Abstract: INDUSTRIAL MEMBRANE SWITCH WITH BREATHER     Abstract of the Disclosure A push button switch has an operator that is mounted for axial movement within a bezel towards its exit end.  A contact assembly is disposed across the exit of the bezel.          The contact assembly includes a pair of termination areas formed on a substrate and a shorting patch disposed on a flexible membrane, the shorting patch being separated from the termination areas by a spacer to provide a switch air gap.  A second spacer is disposed on the other side of the substrate and forms an air reservoir that communicates with the switch air gap through an aperture in the substrate.          When the operator is moved against the membrane to close the switch air gap, air is circulated into the air reservoir increasing the pressure therein, and returns to break the contact of the termination areas with the shorting patch when the operator is retracted.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for feeding electric circuit elements has a hopper for accommodating a supply of such elements, a capture tube or pipe extending substantially vertically through a bore in the bottom of the hopper which is movable relative to the tube in the direction of the axis of the latter so that the electric circuit elements in the hopper are captured one at a time by the tube and fed therethrough to a predetermined position at the outside of the hopper, and a separating plate disposed above the opening of the tube in the hopper for shielding the electric circuit elements under the separating plate from at least part of the weight of the electric circuit elements thereabove whereby the hopper can be provided with a large vertical dimension for accommodating a correspondingly large supply of the electric circuit elements without the danger that elements near the bottom of the hopper will be damaged by reason of the relative movement of the capture tube under the weight of the superposed circuit elements.  Jamming or bridging of the electrical circuit elements above or around the opening to the capture tube is avoided by providing the bottom of the hopper with a conically concave inner surface having a plurality of protuberances thereon, and further by providing a rod extending through the bottom of the hopper and being stationary relative to the capture tube so that the hopper is also movable relative to such rod which has a resilient member extending laterally there-from over the opening to the capture tube.
