Abstract: 1,131,581. Hand brakes. FORD MOTOR CO. Ltd. 17 Aug., 1966, No. 36734/66. Heading F2E. In a hand brake operating linkage an operating handle 11 is connected to a ratchet 35 (Fig. 4) through a lost-motion connection so that the operating handle can be moved back to a retracted position in which the brake is still applied, the operating handle being mounted on a slidable member 12 that slides in a sleeve 13 as the brake is applied, the sleeve being slidably mounted in a housing 21 and is adapted to slide in the housing as the brake is applied. In the brake applied position shown in Fig. 2, the handle 11 is shown in its extended position wherein the slidable member, in the form of a square-sectioned tube 12, attached to the handle 11 is slidable within a square-sectioned sleeve 13 until a stop-plate 17 welded to one side of the tube 12 abuts a collar 16 mounted on the sleeve 13. Movement of the tube 12 within the sleeve 13 is guided by a plug 18 welded in the end of the tube 12. The sleeve 13 is guided in a bush 14 which is rotatably mounted in the stationary housing 21 secured to the vehicle chassis so that the assembly of the handle 11, tube 12, sleeve 13 and bush 14 can rotate in the housing 21. Another stop collar 19 mounted on the lower part of the sleeve 13 is adapted to abut a pawl release lever 24 which surrounds and is a sliding fit on the sleeve 13, the lever 24 being held against axial movement by the housing 21. The ratchet mechanism is adapted to be released by rotation of the handle 11 which rotates the ratchet release lever 24. When the lever 24 is rotated a rod 43 (Fig. 4) actuates a brake linkage 41, 37 to release the pawl 35 from the ratchet teeth 32 formed on a fixed quadrant 31 bolted to the frame of the vehicle. In operation, when the handle 11 is pulled towards the position shown in Fig. 2 the brake rod 38 is applied and through the mechanical advantage linkwork 34, 39 the brakes are applied. The handle 11, tube 12 and sleeve 13 can now be pushed back to a released position wherein the collar 16 abuts against the housing 21. A lostmotion device oonstituted by a flexible cable 22, or by the fact that this cable 22 can slide through the plug 18, allows the handle to be pushed back without disturbing the lever 34 and the subsequent parts of the brake linkage. Instead of a mechanical brake linkage the linkage may be power-assisted.

An arrangement for controlling a gridcontrolled rectifier which ensures that a negative blanking voltage is imposed on the grid whenever a positive firing voltage is not present, comprises a bi-stable arrangement of two semi-conductor controlled rectifiers 2, 3. As shown, the firing voltage is derived from a source 11 and applied to the grid via rectifier 2 and a grid leak resistor 7. The blanking voltage from source 12 is applied via a rectifier 3 and deionization resistor 8. Across each rectifier there is connected a commutating capacitor 5 or 6 in series with one winding of an interconnecting transformer 4. Assuming rectifier 3 to be conducting when rectifier 2 fires the previously charged capacitor 5 discharges through it and one winding of the transformer, thereby inducing a voltage in the other winding to shut off rectifier 3. A resistor 9 provides a path for current through rectifier 3 when deionization in the cathode-grid path of rectifier 1 ceases. A resistor 10 is provided so that grid pulses may be detected when the valve is not excited for phasing purposes. Capacitor 14 eliminates voltage disturbances. Further arrangements are disclosed in Figs. 2, 3 and 4 (not shown).

Abstract: 1,079,318. Stretching filaments. X, THERY. Sept. 11, 1964 [Sept. 11, 1963], No. 37308/64. Heading B5B. Apparatus for stretching textile threads comprises a heated rotatably mounted drum provided with a plurality of thread-receiving peripheral grooves, rotatably mounted guiding means for the threads positioned upstream and downstream of the heated drum, and means for varying the speed of rotation of each guiding means, the downstream guiding means being rotated at a tangential speed greater than that of the upstream guiding means. The temperature of the drum, which may be heated by gas or electricity may be thermostatically controlled. Each guiding means may comprise a row of parallel discs which touch each other at their central portions, while the principal faces of the discs slope away from the central portions so that threads led between the discs are gripped. In one embodiment, a layer of paralled filaments 5 (Fig. 1), pass over guiding device 2, to heated drum 1, and thence to guiding device 3, guides 9 and oiling roller 10. Guiding device 3 rotates at higher tangential speed than guiding device 2, the speeds being controlled by variable speed transmission operating from the driving shaft of drum 1, which rotates at a speed between the speeds of the guiding devices. Drum 1, suitably made of copper, is mounted by spider 12 on the free end of driving shaft 12, and is heated by gas burners 13, 14, 15 and 16 mounted on the drum. Temperature control, once the drum has reached the required temperature is effected by closing valve 17 so that gas is supplied, to burners 15 and 16 only, by pipe 18 through electrically-operated valve 19 controlled by expansion gauge 22 located on the wall of the drum (Fig. 4, not shown). Closure of valve 19 restricts the supply of gas to burners 15 and 16 to that flowing through auxiliary pipe 20, which is provided with a manually adjusted valve 21. An intermediate cylinder may be provided, between the gas flames and the drum surface, to prevent local overheating. The thread guiding means consist of a shaft (24), (Fig. 2, not shown), supporting a row of biconical rollers (25) fixed to the shaft by key (26), and retained by nut (27).
