Title: Improvements in or relating to devices for limiting the movement of doors and the like
IPC: E05C17/22
Filed: 1934-05-01
Abstract: 429,406. Stays. SPEGELSTEIN, S., 84, Wallis Road, Hackney Wick, and COOK, C. H., 196, St. Albans Avenue, Bedford Park, both in London. May 1, 1934, No. 13175. [Class 65 (i)] A stay for windows or the like comprises a rod connected to one member for frictional engagement, by transverse movement, with a spring clip connected to the other member, the rod being capable of longitudinal movement when gripped by the clip and having an abutment to engage the clip to limit the longitudinal movement. Fig. 5 shows the clip, which comprises a pair of spring arms 6 bent up from a base 3, pivoted to a fixed plate 8, to grip the stay-rod 1, which rests in notches in plates 4 also bent up from the base 3. The pressure of the arms 6 against the stay produces friction to hold the stay in any position, and the stay can be slid through the clip or engaged or disengaged at any position ; an enlarged part at the end of the stay prevents the stay from sliding endwise out of the clip. The forks of the plates 4 take any side thrust on the stay, which might open the clip, but these plates are not essential. Fig. 6 shows the stay applied to a swing mirror, one of the latter plates, 4<1>, being extended in this case to embrace the stay, which passes through a key-hole slot in this plate 4<1>; the stay can slide in the clip as before, but can only be completely detached therefrom by disengaging it from the spring arms and then passing the enlarged end 1<1> through the large part of the slot in the plate 41. The plate on the mirror to which the stay is pivoted is extended as shown to form a handle 19.

Filed: 1928-05-07
Abstract: 290,170. LebÞgue, (nÚe LeraillÚ), L. May 7, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vaporizers, external.-A multi-tubular exhaustheated vaporizer has, combined with it, means for producing a mixture of water vapour and air to be added to the heated combustible mixture on its way to the engine. A casting 8 encloses two nests of tubes 1, 2 heated externally by exhaust gases flowing through pipes connected to flanges 9. The tubes 1 convey combustible mixture from a carburettor 14 to the induction pipe 3 the flow being controlled by a throttle valve 7. The tubes 2 convey vapour from a water tank 15 filled with absorbent material the flow of vapour being controlled by a valve 16. An automatic valve 5 admits air to the vapour, the mixed air and vapour flowing past a valve 6 into the induction pipe. The valves 6 and 7 can be actuated simultaneously by the accelerator pedal. The fuel used in the carburettor may be heated by flowing through a pipe 18. The tank 15 may be replaced by any suitable device for producing water-vapour. In a modification, the nests of tubes are arranged at right angles to one another instead of being parallel. A light fuel may be used at starting or, in the case of stationary engines, preliminary heating may be employed.

Title: Improvements in or relating to hydraulic control mechanism
Filed: 1941-10-20
Abstract: 553,439. Hydraulic control mechanism ; brakes. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. Oct. 20, 1941, No. 13474. [Class 69 (ii)] [Also in Groups XXXI and XXXIV] A hydraulic control mechanism which is especially applicable for applying a graduated pressure for effecting such operations as starting, stopping, and speed variation is described in connecuon with Fig. 1 for braking or steering an armoured vehicle a fitted with two tracks b passing over driving wheels fitted with brake shoes e actuated by levers a connected to the pistons t of servo cylinders s. The pressure applied to each cylinder s is independently controlled by a lever g arranged to control a piston k fitted with a valve q which when open permits the output of a pressure pump n to be by-passed via pipe p back to a reservoir m. On partial or complete closure of the valve q hydraulic pressure builds up in the cylinder l and cylinder s, and the pressure applied to the lever g to advance the piston k is proportional to the pressure applied to the piston t and thus to the braking pressure exerted. When the valve q is completely closed the liquid has access to both cylinders l, s and the pressures on the pistons k, r, are equal. In a modification Fig. 2, the pressure produced by the pump n actuates a hydraulic motor v which is geared to the mechanism under control. In a further modification a servo-cylinder may be arranged between the pump outlet and the valve q and by-pass p, and pressure builds up in the servocylinder only when the valve q is operated as described 'in the first modification. The invention may be applied 'for -controlling brakes, clutches, and gears on power driven vehicles, or to the operation and traversing of travelling cranes, or the control of vehicle tipping gears. Specification 553,273 is referred to.
