Title: Electrical energy conversion system with bilateral switch
Inventor: JOYCE MICHAEL F
IPC: H03K3/64
Filed: 1978-11-15
Granted: 1982-10-26
Abstract: ABSTRACT Electrical circuits, apparatus and methods for a variety of applications. A switching device subdivides an alternating current input signal into a plurality of lower voltage pulses by switching on and off in response to the characteristics. such as the voltage and current, of the input signal, and the pulses of current are inter-mittently passed to a capacitor in series with the device as the voltage on the input signal is positive-going. When the voltage becomes negative-going, the capacitor is discharged, usually with the pulses passing through the switch in the opposite direction. The circuits may be embodied, in use, in telephones, smoke alarms, visual displays, battery chargers or power supplies for appliances, instruments or scientific apparatus. The switching device is preferably a solid state, symmetrical, bilateral device such as a specially constructed integrated circuit, a silicon bilateral switch, a Diac, or the like. The switch may also be unilateral, or may be bilateral but non-symmetrical for certain applications. Where the device is used as a power supply, and in other applications, a direct or alternating current output is provided which can be very carefully controlled as to voltage with minimum circuitry being necessary to accomplish this purpose.

Abstract: RCA 69,528 ROTATABLE POLARIZATION DUPLEXER   Abstract of the Disclosure The cavity of a rotatable cylindrical waveguide supports the TE11 mode of propagation of a received wave and a transmitted wave.  The proximal and distal ends of the cylindrical waveguide are adjacent and axially aligned with one end of a rectangular flexible waveguide and a fixedly disposed horn aperture, respectively.  The transmitted wave propagates in the TE10 mode through the rectangular waveguide to the cylindrical waveguide. Additionally, the rectangular waveguide prevents propagation therethrough of the received wave.  The cylindrical waveguide couples the transmitted wave to the horn. Rotation of the end of the rectangular waveguide rotates the polarization of the transmitted wave.  A pair of slots in the cylindrical waveguide form passageways between the cavity thereof and a pair of filters that pass the received wave whereby the received wave propagates through the filters.  Rotation of the cylindrical waveguide rotates the polarization of the received wave within the filters relative to the polarization of the received wave within the cylindrical waveguide.

Abstract: LATCHING MEANS FOR SWITCH OPERATOR UNCOUPLING MECHANISM           Abstract:  Disclosed is an operating mechanism for high voltage switches that incorporates certain uncou-pling, drawout, and interlocking features.  The operating mechanism is mounted on rollers which roll in tracks on upper and lower mounting brackets attached to the side of the equipment enclosure also containing the high voltage switches.  In the test position, the switch operating mechanism is uncoupled from the high voltage switches thereby permitting the switch operating mechanism and its control circuits to be exercised without moving the high voltage switch contacts.  In the maintenance position, the switch operating mechanism is accessible for conducting maintenance.  A latching mechanism secures the switch oper-ating mechanism in its test and maintenance positions.  By operating a drawout latch lever which is located on the control panel of the operating mechanism on the outside of the equipment enclosure, the latching mechanism can release the switch operating mechanism from the test or maintenance positions permitting it to be reinserted or withdrawn farther. The drawout latch lever on the control panel of the switch operating mechanism also indicates when the switch operating mechanism is in the test or maintenance positions.  The coupled position of the switch operating mechanism is sensed electrically by a position indicating switch.  A locking mechanism prevents any movement of the high voltage switch while the door of the equipment enclosure is in a predeter-mined position or while the switch operating mechanism is uncoupled.  An indicator on the control panel indicates the position of the high voltage switch.

Abstract: ABSTRACT OF THE DISCLOSURE         A scroll-type refrigerant compressor unit is obtained in which any deflection and undesired vibration of moving parts are prevented by a simple construction and in which the orbiting scroll member is prevented from rotating by a simple mechanism.  A disk rotor having a drive pin is mounted on an inner end of a drive shaft which is rotatably mounted through a front end plate of a compres-sor housing.  The disk rotor is rotatably supported on the inner surface of the front end plate through a thrust bearing.          The orbiting scroll member is rotatably mounted on the drive pin.  The orbiting scroll member has a radial flange inte-grally formed with the scroll member which flange is supported on the disk rotor through a thrust bearing.  Therefore, drive shaft, disk rotor, drive pin and orbiting scroll member are supported without undesired deflection and vibration during operation.  A ring like slider plate member is disposed between the radial flange and the end plate of the orbiting scroll member.  The slider member is so connected to the end plate of orbiting scroll member by key and keyway connection that the relative rotation of them may be prevented while the relative movement of them in a radial direction being permitted.  The slider plate member is also so connected to a member fixed to the inner surface of the compressor housing by key and keyway connection that the relative rotation of them may be prevented while the relative move-ment of them being permitted in a radial direction per-pendicular to the relative movement between the slider member and the orbiting scroll member.  Those keys and keyways may be preferably so formed that the contact surface between mating key and keyway for receiving rotational torque is on a diameter of the slider member.
