Patent GB-878894-A (GB)
Abstract: 878,894. Gyroscopic apparatus. SPERRY GYROSCOPE CO. Ltd. Dec. 5, 1958, No. 39229/58. Addition to 857,552. Class 97(3) In gyroscopic apparatus according to parent Specification, the warning indicator has an electrical actuator energized through a circuit including a switch which operates in response to the operation of the caging mechanism. As shown in Fig. 1, an electronic inverter 1 is supplied by a D.C. source and has an A.C. output, with a tapping which gives less than full voltage. The rotor is driven by a split-phase motor having windings 3, 5 connected to a condenser 4. A high voltage is applied to the rotor until it has run up to speed, whereupon the lower voltage is applied by a manually operated switch 2. The rotor casing is suspended in a gimbal and its spin axis is maintained vertical by known gravity-responsive means. The apparatus is provided with a horizon indicator as described in Specification 805,947, and a caging mechanism as described in Specification 878,891. A warning indicator 6, mounted on the gimbal, is spring-urged into a position in which it is visible through a window, but is withdrawn from view when an electromagnetic actuator 7 is energized. The energizing circuit is completed through the motor windings and through a switch 8 which is actuated by the caging mechanism, so that the indicator is withdrawn only when the motor is energized and the gyroscope is uncaged. The arrangement described is suitable for light aircraft; an arrangement more suitable for other aircraft is shown in Fig. 2, where the voltage is charged automatically from a high to a low value after an interval of 45 sec., by means of relays connected across the D.C. supply to the inverter 1. On switching on, a relay 10 is energized, switching switch 2 to the high voltage position and closing switch 11 to energize a solenoid 12, by which the gyroscope is caged. A thermal relay 12a is also energized, and after an interval of 45 secs. closes a switch 13. This energizes a relay 14, which operates switch 15 to de-energize thermal relay 12a and to complete a holding circuit, and also operates a switch 16 to de-energize relay 10. Switch 11, previously closed by relay 10, now opens to de-energize solenoid 12 (uncaging the gyro), and switch 2 connects the low voltage tapping of the inverter to the motor windings. The movement of the caging mechanism operates switch 8 to energize actuator 7, which withdraws indicator 6 from view. The arrangement of Fig. 1 is supplied by a battery, and that of Fig. 2 by a generator with a stand-by battery. To protect the equipment from the voltage surge which may occur on starting the generator, an overload relay 17, actuating switches 18, 19 in the inverter supply circuit, is connected across the D.C. supply.

Title: Improved linkage assemblies for transferring rotary motion to specimens
Inventor: DALEY JOSEPH WILLIAM
IPC: G01M13/02
Filed: 1991-01-28
Abstract: A vehicle spindle test fixture (10) that permits applying a brake load torque to the spindle or test unit (11) has a loading actuator (95) that permits high input force levels, while keeping the coupled mass that must be moved during the test operation at a resonably low level. In testing a vehicle spindle (11) ideally, the mass carried by the test spindle (11) would be equal to the mass of the wheel and tire used on the load. Because of larger physical sizes, the linkage design problem has become more difficult. The present invention reduces the total coupled mass for brake torque testing by utilizing a unique linkage arrangement (50) that reduces the size of the input linkage (80) as compared to the output linkage comprising the test spindle (11) by providing diverging links (51) which are connected at their upper ends to the text spindle (11). <IMAGE>

Title: Fsk demodulator
Inventor: ZEHNGUT ILAN
IPC: H04L27/156
Filed: 1992-02-20
Abstract: An FSK demodulator is provided comprising means for receiving and digitizing an FSK signal (such as a signal comprising two frequencies f1 and f2 in which first and second logic states are represented by first and second periods of different durations). First, second, third and fourth consecutive transitions of the signal are identified and the times of said transitions are identified. A first period between the first and third transitions is calculated, as is a second period between the second and fourth transitions. A change of frequency in the signal is indicated when the first and second periods lie on opposite sides of a first threshold period ( tau ) and no change of frequency is indicated when the first and second periods lie on the same side of the threshold period ( tau ). In a further aspect of the invention, a transition is rejected as illegal when two consecutive transitions occur within a predetermined period of time. This demodulation technique can have a software implementation suitable for a general purpose microprocessor. <IMAGE>

Patent GB-2298533-A (GB)
Title: Overvoltage protector
Inventor: MAYTUM MICHAEL JOHN
IPC: H04M3/18
Filed: 1994-07-29
Abstract: The purpose is to provide a protection circuit which passes all normal operating voltages on ring and tip telephone wires and limits the peak voltage increase during a lightning impulse to a level comparable to the battery voltage. For example, normal operating voltages of 200 V peak would be passed, and under lightning impulse conditions the voltage increase would be limited to about 90 V. The circuit has a two terminal voltage responsive thyristor PA1 in series with a gate triggered thyristor PB. A lightning impulse causes a capacitor C to pass sufficient current to trigger thyristor PB, whereas under AC disturbing voltage conditions the thyristor PB is triggered by a symmetrical avalanche diode D. The switching speed of thyristor PB is made very fast by its having a low holding current (eg. 10 mA). Thyristor PA1 has a higher holding current (eg. 150 mA) and so turns off before thyristor PB after an overvoltage. A resistor may be connected between the gate and MT1 (ground) terminals of thyristor PB to reduce its variation of triggering current with temperature. Parts or all of the circuit may be integrated (Fig. 6); circuits for the ring and tip wires may be integrated on a single chip.
