Title: Brake system with wear-compensated means
IPC: F16D65/56
Filed: 1967-04-13
Abstract: A fluid-operated disc brake has a slack adjuster disposed within and between two opposed brake operating pistons 3, 4, the adjuster including a resilient, deformable member 11 which yields when the fluid pressure exceeds a selected value to render the adjuster inoperative. The disc brake has a caliper 1 and a cylinder 2 containing the opposed pistons 3, 4. A pin 9 extending through the zones of the two pistons is in screw threaded engagement with a sleeve 8 receiving a Belleville washer 13 which abuts a ring 10 in the piston 3. The washer 13 is arranged to deflect only when forces greater than the normal brake applying forces are applied. Passages 17, 19 in the pin permit the passage of hydraulic fluid therethrough. On operation of the brake with normal forces a pin 14 carried on the pin 9 rides along an inclined surface 18 of a notch in a flanged member 13, the latter being held against rotation by friction between the flange and a ring 15, the pin 9 thus rotating in sleeve 8, against spring 12, to take up the normal clearance. On release of the brake spring 12 resets the member 13. If excessive brake-applying force is applied the Belleville washer 11 yields, preventing the slack adjusting mechanism taking up clearances due to bending of the caliper.

Title: Circuit breaker rotary handle mechanism cam lock
IPC: H01H71/56
Filed: 1967-11-30
Abstract: A circuit-breaker 10, of the rotary handle type, generally similar to that of Specification 1,130,641, has a cam lock 59 operative to prevent accelerated movement of the cam 45 in the contact-closing direction by action of the cam follower 44 thereon immediately prior to and during the sudden release of the cam follower by the cam to permit contact closing. A handle 49 rotates the cam-shaft 46, and pawls 54 engage teeth 56 on shaft 46 such that cam 45 and plate 52 are rotated and cam 45 acts on a cam follower roller 44 to provide a step-type ratcheted operation of a reclosing lever 37 against springs 33 and then suddenly releases it to close contacts 27, 35 rapidly as roller 44 drops into notch 68 of cam 45. The cam lock 59 is pivotally supported on a pin 57 and is spring-biased clockwise such that a portion 62 engages a slot 63 in shaft 46 to prevent the relative rotation of cam 45 and shaft 46 in the "closing impending" position of roller 44 on cam 45. The cam lock portion 62 is released after roller 44 drops into notch 68, but a portion 69 enters slot 63 to lock the shaft 46 until the breaker has been tripped manually by a trip member (not shown) or by current-responsive means. When latch 21 is moved to released position, lever 37 moves such that the cam lock 59 allows rotation of the shaft 46 with respect to cam 45 to recommence ratchet operation. A pivoted indicator arm 71, visible through an opening 73, Figs. 7, 8 (not shown), in the breaker housing, indicates the condition of the breaker contacts, and an indicator ring 65 indicates the rotated condition of cam 45, Figs. 2, 3B, 4B, 5B (not shown).

Patent ES-353707-A1 (ES)
Title: Metallic coating method
IPC: C23C2/20
Filed: 1968-05-09
Abstract: Ferrous metal strip is coated with molten metal by (a) cleaning the surface of the strip and bringing its temperature to that of the molten coating metal (b) passing the strip through a bath of molten coating metal and withdrawing it in a generally vertical path of travel (c) impinging a substantially laminar flow jet of gaseous fluid on the surface of the strip as it emerges from the bath at a height where the thickness of the coating metal is in excess of the desired final coating thickness, the impinging jet returning a continuous flow of the molten metal to the bath while a desired quantity of molten coating metal adheres to the strip and (d) contouring the narrow dimension of the gaseous jet across a portion thereof so as to proportion the wiping effect and leave a uniform coating thickness across the entire width of the strip. For instance, bowing of the strip is compensated for by widening the nozzle across part of its length, this being achieved by using a nozzle of the kind described in U. S.A. Specification 3, 314,163. The maximum velocity of the jet should be at the point of exit from the nozzle, and there should be a sharp velocity gradient across the narrow dimension of the jet, to avoid turbulence and consequent distortion of the coating, which may be of Zn, Al, or terne.
