Title: Flywheel
Inventor: JACKEL JOHANN
IPC: F16F15/139
Filed: 1988-12-29
Abstract: A flywheel 1 is described for absorbing rotary shocks in the drive train of an internal combustion engine. A rotary-elastic damping device is mounted to act between two flywheel masses 3, 4 which can rotate relative to each other. One flywheel mass 3 is connectable with an internal combustion engine and the other flywheel mass 4 is connectable with the input part of a gearbox. Starting from a rest position or middle position of the flywheel masses, during relative rotation of the latter in at least one direction of rotation, a first damper 27 acts substantially alone over a first angle range with a lower rate of rotation resistance moment and at least one additional damper 45a acts over a following second angle range with a larger rate of rotation resistance moment. <IMAGE>

Title: Circuit for generating a reference voltage
Inventor: SEO DONG-IL
IPC: G11C11/4074
Filed: 1989-01-10
Abstract: A circuit for generating a reference voltage (Vout) comprises first means (10, 20, 30) for providing an input bias (node A) below an externally applied voltage (Vcc) and reducing the variation of the bias voltage level (node A) due to variations in the applied voltgage (Vcc). Second means (40, 50, 60) causes a current to flow, depending on the output of the first means, senses the applied voltage (Vcc) and generates the reference voltage (Vout) from the sum of a voltage dropped across a resistance (54, 55) by the current and a fixed constant voltage (node D). Third means (70, 80) absorbs or supplements a part of the current flowing in the second means, according to variations of the applied voltage (Vcc). The circuit is for use with an address buffer in a dynamic random access memory. <IMAGE>

Title: Improvements in and relating to amplitude-modulation transmitting devices for compatible single sideband transmission systems
IPC: H04B1/68
Filed: 1964-01-08
Abstract: 997,971. Single sideband amplitude modulators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 8, 1964 [Jan. 11, 1963], No. 891/64. Addition to 976,235. Heading H3R. Relates to a compatible SSB system as in the parent Specification, wherein a single sideband a cos (# + p)t derived from a filter 6 together with carrier cos wt added at 37 is modulated by itself in a second modulator 9 to produce from a filter 10 a frequency band cos 2# + 2a cos (2 W  + p)t + a<SP>2</SP> cos (2w + 2p)t whose modulation envelope is 1 + a<SP>2</SP> + 2a cos pt, i.e. is reproducible in a double sideband receiver without distortion, and in which further, any amplitude modulation due to intermodulation between frequency components of the modulating signal is eliminated by a limiter 28 and then the limiter output amplitude modulated at 30 by the modulation signal obtained from a synchronous detector 19 fed by the single sideband output and carrier source 5. Residual frequency components of the suppressed single sideband are here further reduced by altering the amplitude a of the single sideband output a cos (# + p)t from filter 6 by a factor (1+a<SP>2</SP>) to produce a non-linear amplitude a( 1+ a<SP>2</SP>) so that the ratio of modulation index of the signal fed to the limiter 28 relative to the modulation amplitude progressively increases with the latter. To this end the output amplitude a of S.S.B. filter 6 is detected by rectifier 40 and after amplifying applied to a non-linear network 39. In Fig. 4 the S.S.B. from filter 6 is applied to a transistor 44 acting as an emitter follower for S.S.B. output to terminal 56 and as an amplifier feeding an NPN transistor 48 acting as a rectifier with D.C. output varying a voltage variable resistor 53 in its collector circuit so that the output from potentiometer 53, 54 increases with collector D.C. current i.e. input S.S.B. amplitude to transistor 44. Alternatively, variable-Á valves or rectifiers acting as variable resistors may be used for the non-linear network 39. The modulation index increase by a factor (1+a<SP>3</SP>) may also be obtained by a non-linear network in the lead 38 adding carrier to the single sideband, or in the modulation input to output modulator 30.

Patent GB-911044-A (GB)
Abstract: 911,044. Controlling burners. ELECTRONICS CORPORATION OF AMERICA. Jan. 9, 1959 [Jam 10, 1958], No.933/59. Class 75 (1). [Also in Group XL (b)] A burner control system in which a flame relay, controlled by a flamesensing device and associated circuitry, is effective to prevent the flow of fuel in the absence of a flame includes means to generate a checking signal to operate the relay independently of the flame condition. This signal is automatically applied as a check on the relay's action immediately before ignition and may also be re-applied during ignition to prevent premature shut-off of the fuel while the flame is becoming established. As shown, the flame is sensed by the parallel combination of probe 77 and photo-cell 71 which, with flame present, cut off triode 87 so that triode 99 conducts and energizes the flame relay 107 whose contact 53 is thereby held closed to allow continued supply of fuel to the burner through electrically-operated valve 63. In the absence of a flame, triode 87 normally conducts to produce cut-off of triode 99 and consequent de-energization of relay 107. Before ignition of the burner all the switches of the circuit are in the condition shown, but when switch 51 of transformer relay 49 is closed (by a thermostatic device controlling the burner's operation), the current in coil 122 increases to close associated relay contacts 47 and 111. The latter provides the checking signal by charging capacitor 95 to cut off triode 87 and energize relay 107, whose contact 27 then moves to start a timer motor 29 by which the remaining switches of the circuit shown are operated in the sequence necessary to ignite the burner, the removal of the checking signal being effected by the opening (effected by the timer motor) of switch 119, and the reapplication of the checking signal during flame build-up by its reclosure. The ignition procedure terminates with switch 23 closed, switches 39 and 45 open and relay contact 27 on terminal 41 as a result of the presence of a flame energizing its relay 107. When the thermostat contact 51 subsequently opens, switch 47 opens to stop the burner by the isolation of ignition and fuel controlling devices 59 and 63, the flame disappears and, contact 111 I also being open, relay 107 drops out so that the consequent changeover of its contact 27 re-starts the timer motor 29 to reset all the switches in preparation for the next automatic ignition. Should the flame fail while switch 51 is closed, relay 107 drops out to open switch 53 and also to start the switching-off sequence of the timer motor at contact 27. An alarm 66 is actuated by the movement, controlled by the tinier motor at the end of its switching-off sequence, of switch wiper 35 on to contact 65, the wiper being mechanically coupled to the armature of relay 49 in such manner that it can only move when the relay 49 is energized in order that the alarm will be given when the flame fails, but not when it is deliberately shut off by the opening of contact 51.

Title: Electroclinic liquid crystal devices
Inventor: PRYCE G J
IPC: G02F1/141
Filed: 1991-05-22
Abstract: An Electroclinic (EC) Liquid Crystal Device comprises a ferro electric smectic A type material in a liquid crystal cell. This cell is formed by two glass walls carrying transparent electrodes spaced 1-10 mu m apart by a spacer. The inside face of both walls is surface treated to align and provide a surface tilt to contacting liquid crystal molecules. Poor appearance, due to discontinuities within the smectic A layer, are overcome by an alignment that provides a surface tilt of 2-9 DEG . This alignment is provided by a layer of e.g. polyimide cured to about 200-300 DEG C for about 1 to 6 hours, then rubbed in a single direction with e.g. a nylon cloth. The liquid crystal director can be rotated typically by +/- 12 DEG  by application of positive and negative applied voltages, typically about 30 volts. The angle of rotation varies approximately linearly with voltage. The device may be used as a spatial light modulator. <IMAGE>
