Title: Deployable fin assemblies for self-propelled projectiles
IPC: F42B10/14
Filed: 1961-07-06
Abstract: 945,409. Tail assemblies for self-propelled missiles. HOTCHKISS-BRANDT. July 6, 1961 [July 11, 1960; June 15, 1961], No. 24444/61. Heading F3A. An extensible projectile fin arrangement for self propelled missiles of the type wherein the fins pivot in longitudinal radial planes about pivots positioned near the forward ends of the fins is characterized by the fins being acted on by a thrust ring movable along the longitudinal axis of the projectile between a forward position in which the fins are folded rearwards and a rear position in which the fins are extended, and by the provision of thrust exerting means. A retaining ring 27 is removed prior to placing the projectile in a launching tube. On firing the propellent charge in the chamber C, combustion pressure is transmitted through orifices 32 to pistons 30 which force a ring 29 rearwards thereby extending the fins after leaving the launching tube. The fins are retained in their extended position by interlocking of a cylindrical portion 35 of the ring 29 with the fin portion 40 (Fig. 3). In a second embodiment the nozzle T is in one piece, and in a third embodiment of similar construction to that shown in Fig. 1 the pistons are replaced by compression springs; these springs may be replaced or supplemented by powder charges (independent of the main propellent charge) which act against pistons in closed cylinders.

Title: Improvements in means for facilitating the starting of internal combustion engines for motor vehicles using a vacuum-governed fuel injection pump
IPC: F01L13/00
Filed: 1937-09-08
Abstract: 491,274. Speed governors. AUSTIN MOTOR CO., Ltd., and COLELL, R. F. Sept. 8, 1937, No. 24449. [Class 57] The regulating rack C of a fuel injection pump A is connected to a diaphragm D loaded by a spring F and located in a chamber E connected by a pipe e to the air induction system between the engine and a throttle valve. A centrifugal governor H is mounted on the shaft B and the sleeve K is loaded by a spring L and actuates a lever M having a stop P to limit the movement of the rack C in a direction to increase the fuel supply. During running under load, the governor holds the sleeve K against the stop g<1> but when at rest the spring L moves the stop P to allow more fuel to be used during starting.

Title: Improvements in or relating to toe lasting devices for shoes
IPC: A43D21/12
Filed: 1924-10-23
Abstract: 246,220. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Oct. 23, 1924. Lasting.-In a toe-lasting mechanism a resilient support is provided for the toe end of the last and a flexible apron interposed between the upper and wiping means is adapted to wipe the upper in a direction towards the shoe bottom. The last is supported on a heel post vertically movable under the action of a spring 8, and at the toe end by a box 162 containing a block 164 of soft rubber having a recess 166 shaped to, but smaller than, the forepart of the shoe. A slide 168, Fig. 4, on the box 162 carries wiper members 170 normally opened by spring 172 to an extent limited by arms 174 of the slide 168. Additional wiper members 176 mounted on slides 178 are adapted to be closed on the shoe by means of toothed sectors 186 oscillated by the arms 174 acting through pivoted members 190. The wipers 176 may be adjusted by screws 192. Arms 184 on the slides 178 impart closing movement to the wipers 170 as the slides 178 advance. The box 162 is adjustable in curved guideways 202 on a bed-plate 206 by means of a screw 212 and hand-wheel 220. The bed-plate 206 is adjustable by means of rack-teeth 224, a pinion 226, and hand-wheel 230 on a slide 222, which has a movement lengthwise of the shoe in time relation with the operations of other parts of the machine. A gauge-plate 240 is fixed above the wipers to assist the operator in positioning the toe-lasting mechanism lengthwise of the shoe. The slide 168 is provided with rack teeth and is operated by a pinion carried by a shaft 422 rotated from a cam in the lower part of the machine through bevel-gearing and a telescopic shaft. The jacked shoe is depressed to the level of the wipers by presser feet 252, 270, which are simultaneously lowered by a pinion shaft 282 operating on slides 246, 276. The wipers operate on the upper through a rubber apron 196, Fig. 2, secured to the box 162 and sufficiently wide to lie between the shoe and the pad 164. As the shoe is forced downwardly into the toe-lasting mechanism the apron 196 wipes the upper about the sides and end of the last, and a movement of the toe-lasting mechanism to the left is then produced to assist in drawing the upper forwardly on the last. For this purpose a roll 372 on the slide 222 is engaged by a cam 374 fast on a vertically-movable rod 274. A cam face 376 on the rod is arranged to return the slide to the right. In operation, the upper and insole are put in position, the last is forced into the lasting mechanism by the presser feet, the lasting mechanism is moved to the left to cause the apron to wipe the upper forwardly, and the wipers then lay the margin of the upper over the insole.
