Patent GB-1288030-A (GB)
IPC: B60T8/58
Filed: 1970-10-22
Abstract: 1288030 Aritiskid braking systems GOODYEAR TIRE & RUBBER CO 22 Oct 1970 [18 Nov 1969] 50114/70 Heading F2F An electrical signal, directly proportional to the brake pedal force is compared with a further signal, the amplitude of which is inversely proportional to the amount of skidding, and the lower of the two currents drives a valve 40 to decrease the hydraulic pressure supplied to a brake 44 for a rotating element 46. As shown, two pedals 10, 12 for different operators may be provided each of which actuates a pair of linearvariable differential transformers 18-18a and 20-20a respectively providing A.C. signals, of an amplitude directly proportional to the pedal force, which are rectified in rectifiers 22, 24, amplified at 26, 28 and fed to a circuit 30 that transmits only the higher of the two signals. The higher signal is fed to a circuit 36 having a second input which is an antiskid signal 52 which decreases in proportion to the amount of skidding by the provision of a shunt 56 and current to voltage circuit 58 which is fed with a current from a constant current source 54. When a skid develops signal 52 causes shunt 56 to divert from source 54 a current directly proportional to the amplitude of the antiskid signal. The output of circuit 58 is then zero and this is recognized as the lowest of the two inputs to a circuit 36 and is the controlling signal for valve 40. If the force on pedals 10, 12 is reduced so that the brake pressure is below the skid threshold, valve 40 once again becomes controlled by the braking circuits. Pedals 10, 12 are provided with springs 14, 16 which simulate the pedal action of a completely hydraulic braking system.

Title: Circuits for operating electromagnetic energy generators
IPC: H03B9/10
Filed: 1973-11-06
Abstract: 1410864 Supply circuits for microwave ovens AMANA REFRIGERATION Inc 6 Nov 1973 [11 April 1973] 51510/73 Heading H2H A supply circuit for the magnetron 38 of a microwave oven 10 comprises an electromagnetic radiation detector 62 which supplies a signal to a control circuit 12 to disconnect a supply source 64 from the magnetron during a predetermined period of time following initial energization of the magnetron. The source 64 energizes a relay 70 via a thyristor SCR1 and bridge circuit 76 so that the relay enables the source to be connected to the supply 40 which provides heating of the magnetron filament and the magnetron anode voltage. The detector 62 is a silicon or germanium diode which detects the electromagnetic radiation and supplies a signal to an amplifier 78. When the amplified signal reaches a level sufficient to trigger a unijunction device 86, a transistor 88 is switched on thereby switching off the thyristor SCR 1 and de-energizing the relay 70 to disconnect the supply 64 from the magnetron supply 40. The relay is held de-energized for a period of time determined by the discharge of a capacitor C5 whilst the magnetron reverts from an initial unstable oscillation mode to the normal operating mode. When the unijunction device 86 becomes non-conductive due to the discharge of the capacitor C5 through a thyristor SCR2, the transistor 88 is switched off thereby allowing the thyristor SCR1 to conduct and the relay to be re-energized. The thyristor SCR2 remains conductive to prevent further triggering of the unijunction device except when the source 64 is turned on again after having been turned off.

Abstract: 1,214,131. Door closing mechanism. BRENT METAL WORKS Ltd. 20 Feb., 1968 [21 Nov., 1966], No. 51979/66. Heading E2M. A closing mechanism for a double-swing door has a helically coiled spring 12 with its longitudinal axis parallel to and disposed midway between the slide bars 6, 7. These bars have toothed racks 6a and 7a respectively between which fits a toothed pinion 9 secured to the actuating spindle 8. Each bar supports two lugs 10 and 11 which are at such a distance apart as to keep the spring 12 slightly compressed in the rest position shown i.e. when the door is closed. When the door is opened the bars 6 move in opposite directions as they rotate about spindle 8, pinion 9 and the spring is compressed by one of each pair of lugs 10 and 11 thus increasing its stored energy. The mechanism is secured to or embedded in the door and contained between two planes defined by the front and rear surfaces of the door rail. A hydraulic damper device is employed to control the rate at which the spring means returns the door to its closed position after rotation of the latter.

Abstract: 1,127,542. Mine face conveyers. A. HAARMANN. 16 Dec., 1965 [17 Feb., 1965], No. 53491/65. Heading B8A. Each trough section 4a of a coal face conveyer is associated with three guide beams 5 which consist of hollow sections formed with longitudinal splines 5a. These splines engage in grooves provided in sleeves 14 which are longitudinally slidable on the beams 5 but which are unable to rotate thereon. Each sleeve 14 is secured by a strap 13 to an hydraulic prop 6 and each beam 5 is connected to the trough section 4a by a crosshead 9 received in a box 10 on the section 4a. Tensile forces on the beam are taken up by a cover 10a for the box, and thrust is absorbed by a leaf spring 12. The props 6 are advanced by hand and the conveyer may be sided over by single acting rams. Alternatively, if at least one of splines 5a is provided with rack teeth for engagement by a pinion in the sleeve 14, a motor drive may advance the conveyer and props. In a modification, Fig. 6, a guide beam 15 incorporates a ram device of which the portion 15a connected to the conveyer is, at its other end, connected by a knuckle joint 26 to a movable cylinder 24 of the ram. An outer member 16 of the ram is secured to the base 17 of a support element having hydraulic props 18, 18a connected by a roof bar 19. This bar is coupled at 20 to a further roof bar 21 for a prop 22. A soleplate 23 connects the foot of the prop 22 with the twin prop support element.

[Also in Division B6] A silicon wafer containing a plane PN- junction near one surface is bonded at that surface to a heat sink. Material is next uniformly removed from the other surface to thin the slice which is then oxide-masked and etched to delineate individual diodes. The resultant structure may be any of those shown in the figure, that of figure 3a being suitable for the production (by division of the heat-sink) of individual diodes. The preferred use is to parallel the individual diodes and use them in a single cavity as an avalanche microwave oscillator. Typically the heat sink is a copper plate and it and the silicon wafer, which is titanium-coated on its bonding face, are both coated with silver or gold so that they may be thermo-compression bonded together. Thickness reduction of the silicon may be by mechanical polishing and/or planar etching. The oxide mask may be silica produced by anodization or may be vapour deposited silicon monoxide. The structure shown in Fig. 3b may be formed using an etchant selective for N-type material. In making the structure of Fig. 3c etching is stopped at a point close enough to the junction that the diodes formed may be isolated in use by a depletion region associated with the reverse biased junction.
