Title: Rotary drive mechanism
IPC: A47C1/024
Filed: 1980-05-13
Abstract: A rotary drive mechanism comprises an input drive pinion 20 for driving an output spindle 12 through the agency of a coupling which prevents the pinion 20 being driven from the output spindle 12. The coupling comprises a detent arrangement 46 which is operable to prevent rotation of the input pinion 20 except when rotational drive is imparted via the pinion itself, in which case the detent 46 is released from a toothed disc of the pinion 20 by means of a cam disc 24 moving a follower 40 connected to the detent 46. The cam disc 24 is formed with a recess 48 into which a correspondingly shaped projection (not shown) of the toothed disc of the pinion is disposed with lost motion. Initial movement of the cam disc lifts the follower 40 when taking up the lost motion. <IMAGE>

Patent GB-2079104-A (GB)
Title: A pulse width modulation system
IPC: H03F3/217
Filed: 1980-06-18
Abstract: A first source (1) of voltage V supplies power to the R.F. stage (7) of a radio transmitter. A second source (9) of voltage 2V +  delta V powers a pulse width modulation amplifier (8) serving to amplify an incoming audio signal (A). The amplified signal (A) is applied, via a capacitor (16), to the load, thereby modulating the voltage V. Because the voltage of the second power source more than exceeds twice the voltage V, the amplifier can be operated at less than 100% pulse width modulation whilst still obtaining an amplification sufficient to achieve 100% modulation of the voltage V applied to the load. <IMAGE>

Patent GB-2072972-A (GB)
Title: A current overload detector
IPC: H02H6/00
Filed: 1981-02-05
Abstract: An overload detector for detecting overheating in an electric motor comprises a function generator 16-20 which receives a signal proportional to the motor current and supplies a charging current, representative of the square of the motor current, to a resistor capacitor network 21-27 simulating the thermal capacity of the motor. In this way, the voltage on the resistor capacitor network represents the temperature of the motor. A high input impedance comparator 28 having at least its input formed by MOSFET devices compares the voltage on the resistor capacitor network against a reference voltage, and then the output of the comparator provides an indication of overheating of the electric motor and can be coupled to a circuit breaker to isolate the electric motor from its power supply. The comparator exhibits an adjustable amount of hysteresis (34-40) to prevent restarting of the motor until it has cooled sufficiently to cope with the high starting currents. <IMAGE>

Title: Transmission shift control guide and detent apparatus
IPC: F16H63/10
Filed: 1981-04-27
Abstract: Transmission shift control guide and detent apparatus includes a mechanism for defining the shift path for any given gear change, and for providing detenting both for ratio selection and for engagement of the selected gear set. A guide plate defines a predetermined track. A pin associated with the transmission shift lever is movable along this track to establish a precise definition of the path for each selecting and engaging movement. The plate also defines a plurality of depressions which form a detent map. A spring-loaded ball is moved over this map by the action of the transmission shift lever. This develops predetermined resistive forces against which the shift lever must be moved during the selecting and engaging movements. Stresses are absorbed in the guide plate rather than in the shift rail.

Patent GB-2129226-A (GB)
Title: Resonator arrangements
Inventor: GRATZE STEPHEN CECIL
IPC: H01P1/208
Filed: 1982-09-04
Abstract: All dielectric resonators are capable of supporting a number of resonance modes. This may cause difficulties, for example when a resonator is used in a filter circuit and a mode other than that required is present, producing unwanted pass or stop bands at another frequency. These difficulties may be reduced in a filter by employing a plurality of resonators having fundamental modes with the same resonant frequency. Other higher order modes have different frequencies and thus do not reinforce each other to the same extent. Therefore the effect of such spurious modes is reduced.

Title: Temperature sensing device with high resistance connecting leads
Inventor: SATO YOSHIAKI
IPC: G01K7/22
Filed: 1982-09-16
Abstract: A temperature sensor comprises an electrical tempera- tun* sensing element such as a thermistor and a pair of high-resistance conductors of conductive fluorine resin which are electrically connected to the electrical temperature sensing element. The conductors of conductive fluorine resin are disposed on opposite surfaces of a body of fluorine resin. The electrical temperature sensing element may be sandwiched between the pair of high-resistance conductors. One of the conductors may comprise a high-resistance thin metal wire coated with fluorine resin and the other a body of conductive fluorine resin mounted on the fluorine resin coating. Alternatively, the high-resistance conductors may comprise high-resistance thin metal wires coated with fluorine resin and twisted around each other. The temperature sensor thus constructed may be used in microwave therapy as it is less subject to rejection by human body tissues and does. not reflect applied microwaves.
