Title: Improvements relating to gear-changing apparatus
IPC: F16D67/02
Filed: 1966-12-07
Abstract: 1,127,966. Change-speed control; clutchbrake combinations. FIRMA INTOMATIC BASEL A.G. 7 Dec., 1966 [7 Dec., 1965], No. 54850/66. Headings F2D and F2L. In a change-speed control for a motor vehicle wherein a ratio shift electric motor 3 drives a crank 1 connected to a shift lever 6 through a worm and wheel reduction gear 2, a clutchbrake mechanism 4 connects the motor 3 to the worm 18 during ratio shift and on completion of the shift disengages the clutch and brakes the worm 18. A shaft 30 of the worm 18 carries  an axially slidable clutch-brake disc 21 which is normally biased by a spring 25 into engagement with a brake surface 27 on a housing 4. During ratio shift an electromagnet 28 connected in parallel with the electric motor 3 is energized and acts through a rod 20 and pin 22 to move the disc 21 into engagement with a clutch disc 23 on the motor shaft 24.

Title: Blocking oscillators
Inventor: ADAMS DEREK STANLEY
IPC: H03K3/30
Filed: 1965-12-24
Abstract: 1,100,329. Transistor blocking oscillator circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. 13 Oct., 1966 [24 Dec., 1965], No. 54858/65. Heading H3T. The off period of a blocking oscillator is determined by a timing capacitor 14 in the base circuit of a transistor 17 which conducts during the on periods of the oscillator, the transistor emitter current being maintained substantially constant during the on periods so that as the collector current rises the base current decreases until a point is reached at which the transistor turns off. When the transistor is turned off, capacitor 14 charges through resistor 13 until the transistor conducts again, when constant emitter current is maintained due to current through resistance 24 causing the emitter potential to rise. The diode 16 clips the voltage at the junction of resistance 15 and winding 18 and so gives the circuit more predictable characteristics. The diode 22 protects the base-emitter junction and could alternatively be placed between the base and winding 18.

Abstract: 1411020 Valves GUSTAV F GERDTS KG 6 Dec 1973 [23 Jan 1973] 56601/73 Heading F2V  A pressure relief valve closure member 4 is loaded by three equally spaced springs 7, comprising a coil 11 with arms 9, 10, which provide an axial loading which decreases as the valve opens to produce a rapid and complete opening. One end 14 of each spring is pivotally mounted against the closure member and the other end 15 is pivotally mounted against an abutment plate 6 held in a groove in ribs 3 in the housing which guide the closure member. The end in contact with the abutment plate is extended at 17 to engage a groove 16 in the plate. One of these extensions 17 and a nose 19 on the abutment plate coact with one of the ribs 3 to prevent rotation of the plate and also of the closure member. The abutment plate also serves as a stop to limit the movement of the closure member. In an alternative embodiment, Figs. 3, 4 (not shown), the turns of the coil of the springs are spaced axially and the springs are so arranged that they lie between the closure member and the abutment plate and thus provide damping of the last part of the movement of the closure member.
