Patent GB-2253531-A (GB)
Title: Energy saving motor control device
Inventor: BALLS DOUGLAS
IPC: H02P27/02
Filed: 1991-03-06
Abstract: The device is interposed between the mains neutral and the neutral connection to an A.C. induction motor. The operation of the device is as follows:- Triac 6 completes the circuit when energised by triac 7. Capacitor 8 is charged through resistor 9 and variable resistor 10, by the voltage appearing across the terminals 3 and 5, which is the mains voltage less motor back e.m.f. When the capacitor 8 has reached sufficient voltage to overcome the two zener diodes 11 and 12, triac 7 is switched on. Current determined by resistor 13 then flows to triac 6, switching it on, to complete the supply to the motor. A series choke 14, and capacitor 15 provide a reduction in emitted interference. When the motor is running under light loads, the back e.m.f. is high, so the charging rate of capacitor 8 is low, and the time taken to overcome the zeners 11 and 12 and consequently turn on triac 6 is longer than when the motor is running under heavy loads, when triac 6 is switched on sooner. The effect of this is to save unwanted current at light loads and allow it to be used at heavy loads. The device is suitable for use with 3-phase induction motors by inserting a respective device (4, Fig 3) in each phase. <IMAGE>

Title: I.c engine intake throttle body
Inventor: WESTON DEREK JOSEPH
IPC: F02D9/10
Filed: 1991-04-24
Abstract: A plastics body 21 defines a passageway 30 in which is rotatably mounted a plastics valve element 27 with a thickened rim portion 35 having a part spherical outwardly facing surface 34. During initial opening of the valve element 27 from a closed position the cross sectional area between the part spherical surface and the passageway remains constant until the valve element 27 reaches a predetermined rotation where the part spherical surface no longer has any effect thereby producing a more gradual increase in cross sectional area of the passageway 30 for initial valve element 27 opening. The passageway (130, Figs. 9 and 10) may define a step of crescent shape at the junction of two bores (131, 132) with a seal (143). The rim of the valve element (127) opposite the thickened portion (135) has a lip (145) which co-operates with the seal. <IMAGE>

Title: Cooker ovens and shelf supports therefor
Inventor: GOSTELOW BENJAMIN FRANK
IPC: F24C15/16
Filed: 1991-06-03
Abstract: In an oven there are two series of vertically spaced sets of shelf supports 8, one series on each side wall of the oven. The overall length of each support is very much less than the length of the oven side wall. The supports may have support areas 10, 11 (fig. 2) which are laterally spaced from each other, and each support also has a shelf location area 12 which limits tilting of a shelf when in position in the oven. In another embodiment (figs. 5-8), each side wall of the oven is formed to provide two spaced, vertical ribs 40 which serve to position a base 39 which carries the shelf supports 20, 21. The bases are detachably mounted on the side walls of the oven. Alternatively, the shelf supports may be separate components 41 (fig. 9) each individually mounted on the side walls of the oven and each including a shelf location area 44 and a shelf support area or areas 42. <IMAGE>

Title: Dummy plug held by rotary shutter
Inventor: FLETCHER WILLIAM GEOFFREY
IPC: H01R13/443
Filed: 1991-10-04
Abstract: A dummy plug (20) can be inserted into an electrical socket (1). and has pins which move a resiliently biased rotary shutter (2) that obscures at least one of the live or neutral holes. One or more pins of the dummy plug (20) have a notch or recess (25) which allows the shutter (2) to move back to its obscuring position when the dummy plug (20) is in place in the socket. The shutter (2) engages a latching face (26) of the notch or recess and the dummy plug (20) is retained in the socket. Thus the dummy plug (20) cannot be removed from the socket by a child. A tool (30) may be inserted through holes (28, 44) in the dummy plug (20) to move the shutter (2) and allow removal of the dummy plug (20). <IMAGE>

Title: Torque distribution control system for a four-wheel drive motor vehicle.
Inventor: MATSUNO KOJI
IPC: B60K23/08
Filed: 1992-04-24
Abstract: In one version, Fig. 2, ideal lateral acceleration is calculated from sensed speed and steering angle, and an actual lateral acceleration is detected by a lateral G sensor. A breakaway point of tires is determined by comparing the actual lateral acceleration with the ideal lateral acceleration and the operation of a central differential is controlled in accordance with the breakaway point and the difference between the ideal and the actual lateral acceleration.   In another version, Fig. 6 (and Fig. 11), a presumed input torque to the centre differential is calculated from sensed engine speed, accelerator pedal position and gear position; a desired steering characteristic is calculated from sensed longitudinal acceleration and a supposed friction coefficient is calculated from sensed longitudinal and lateral accelerations. These calculated values are used to produce the desired torque distribution ratio and the restricting torque for the centre differential. The rear differential may also be controlled. <IMAGE>

Patent GB-2261089-A (GB)
Title: Data output control circuit
Inventor: LEE HYONG-GON
IPC: G11C29/42
Filed: 1992-10-28
Abstract: In a prior arrangement in which the output of a sense amplifier (31), (Figure 1), connected to a memory cell, is corrected by an error correcting code circuit (35) in an abnormal state of the cell and passed to an output buffer (40A), delays involved in the operation of the correcting circuit (35) may give rise to abnormal data transition of the output of the buffer (40A) if the latter is continuously enabled. In order to avoid this and to reduce the current description of the memory chip and prevent deterioration of data access time for the purpose of improving the yield of the chip, the output buffer is only enabled intermittently by a signal  phi OE produced by a data output control circuit 50A, 50B, 50C, 50D which on detection of a transition in an address signal produces the enabling signal after a delay such that the output buffer is enabled at a time when any necessary correction has been made by the error correcting code circuit. The enabling period of the signal  phi OE is dependent on a delay period of a delay circuit (170), (Fig. 5C), in a controller 50D of the output control circuit. <IMAGE>

Title: Electrical generators
Inventor: BAYLIS TREVOR GRAHAM
IPC: F03G1/02
Filed: 1992-11-19
Abstract: An electrical generator for powering a radio comprises a spring motor (4) which is wound up by way of a key (18) such that the subsequent rotation of a torque drum (8) as a stressed spring (12) unwinds therefrom generates electrical power. The rotational speed of the drum (8) is geared up by gear means (14) and rotates the rotor of an electrical motor (16) to generate an output voltage. The output voltage is regulated by way of a Zener diode (24) and is fed to a radio by way of a jack plug. The simple wind up mechanism has been found to be able to power a radio for the order of one hour. The generator can also be used to charge batteries. <IMAGE>

Title: Expandable gauge bit for drilling
Inventor: TIBBITTS GORDON A
IPC: E21B10/66
Filed: 1994-01-25
Abstract: A drill bit 10 for use with earth drilling equipment, has a body 12 and movable cutting means 44 or blades variably positionable between a first position in which the diameter defined by the cutting means is generally equal to or less than the diameter of the drill bit body and a second position in which the diameter defined by the cutting means is greater than the diameter of the drill bit body. The second, expanded position is assumed by the cutting means when they are in contact with the bottom of a hole and are thereby urged upwardly relative to the bit body. The first, retracted position is assumed by the cutting means when the drill bit is being tripped into or out of the hole and, because the cutting means are essentially retracted relative to the bit body, the drill bit does not become jammed downhole. A fixed-blade adaptation of the invention is also contemplated. <IMAGE>
