Title: Automatic adjusting device for transmission of stresses of any nature, and particularly for brakes
IPC: F16D65/56
Filed: 1930-02-20
Abstract: 355,764. Brakes; mechanism. LAVAUD, D. S. DE, 179, Rue de la Pompe, Paris. Feb. 20, 1930, No. 5706. Convention date, Feb. 21, 1929. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] A device for automatically adjusting the distance between two parts of a transmission system when the stroke exceeds a predetermined value comprises a cam or nut interposed in the system, adapted to be rotated by a ratchet and pawl or equivalent device during the return stroke of the system if the initial stroke exceeds a predetermined value. Figs. 1 and 2 show one construction as applied to a fluid-pressure piston for actuating a brake shoe whereby adjustment is effected to compensate for the wear of the shoe. The plate 3 secured to the fixed part that encloses the brake drum is formed with a hollow cylindrical boss 8 having a spherical seat 9 covered by a rubber cap 13 held at its edge by a member 17 screwed into the boss. A rigid cap 20 slidable in the member 17 engages a nut 24 screwing on the rod 23 of a piston 22 acting on one of the brake segments. When pressure liquid is supplied by passage 11 to a groove 10 in the seat 9, the cap 13 swells and actuates the piston 22 thus applying the brake shoe to the drum. The piston is held against rotation by a pin and groove 32, 33. A number of pawls such as 28 pivoted at 27 on the nut 24 normally engage ratchet teeth 31 on the fixed member 17. If, owing to wear of the brake shoe, the movement of the piston 22 and nut 24 during the application of the brake is sufficient to disengage the pawls 28 from the ratchet teeth, the pawls under the action of a spring 29 engage the next tooth and during the return movement of the piston, the nut is caused to rotate on the pistonrod 23 and thus to reduce the clearance of the shoe with respect to the drum. The pawls 28 and teeth 31 may be replaced respectively by cams and a smooth surface. In another construction, the pawls are mounted on axes parallel to the axis of the screw 24 for engagement with internal ratchet teeth, the groove 33 being given a helical shape so that the piston 22 and the nut are given a part rotation during the stroke. If on the application of the brake the stroke and thus the rotation is sufficient to cause the pawls to slip a tooth of the ratchet the nut is held against rotation on the return stroke and the rotation of the piston relatively to the nut causes the excess of play to be taken up.

Abstract: 1,115,402. Transistor switching circuits. SOC. INDUSTRIELLE DE LIAISONS ELECTRIQUES. 10 Feb., 1966 [15 Oct., 1965], No. 5824/66. Heading H3T. In a time delay switching circuit, pulses from an RC oscillator comprising unijunction transistor T1 are rectified at D2 and incrementally charge a capacitor C2. After a predetermined period depending on the frequency of pulses from T1, unijunction transistor T2 breaks down providing a pulse which initiates operation of an oscillator comprising transistor T 5  the rectified output of which energizes a relay R. Transistors T3 . . . T5 are normally non-conductive until the initial breakdown of unijunction transistor T2, when T4 is turned on, saturating the core of transformer L1, L2 which had previously prevented oscillation of T5. T2 becomes non-conductive when C2 has discharged, so that a positive-going pulse is passed via capacitor C3 to the base of T3 so as to raise the base potential of T5 and thus initiate oscillation which is rectified at D3 so as to energize relay R.
