Title: Improvements in rocket motor assemblies
IPC: F02K9/62
Filed: 1959-07-16
Abstract: 885,490. Rocket motor assemblies. GENERAL ELECTRIC CO. July 16, 1959 [July 21, 1958], No. 24463/59. Class 110 (3). In a rocket motor assembly, the propellant container is of ring form, either circular or polygonal, and a series of rocket motor units is mounted therearound and connected thereto so as to discharge at right angles to the plane of the ring. The cross-section of the container may be round, elliptical or approximately square. In the case of mono-fuel a single fuel container is provided but where fuel and oxidizer are used two concentric containers each of ring form are provided; alternatively a single container may be partitioned to provide two compartments, The container 10 in Fig. 1 is of toroidal form and a series of rocket motor units 11 each comprising a combustion chamber, a propellant injector and a propulsion nozzle is mounted thereon, each motor discharging normally to the plane of the container 10. In Fig. 2 the combustion chambers 17 are disposed along either side of the propellant container 10 which is of square cross-section, the gases discharging along the surfaces of the guide member 18. The combustion chambers 17 may each be divided into short lengths. The fuel container 10 in Fig. 4 is partitioned to afford fuel and oxidizer chambers 22, 23 which are connected to the injectors 24 by ducts 25, 26. The combustion chambers are shown at 28 and the combustion gases discharge through the outlet nozzles along the sides of the guide plug 29. A divided combustion chamber 34 is shown in Fig. 6, the propellant injector being indicated at 33 and the dividing baffles at 36. Rocket motor assemblies may be arranged in stages. The object of the invention is to provide a rocket assembly capable of providing thrust of the order of fifty million pounds. Specification 885,489 is referred to.

[Class 52 (v).] Awning side-curtains of the kind adapted to be collapsed fanwise have narrow stiffeners 16 disposed along the folding lines of the fabric of such a length that the curtain is left unstiffened adjacent the pivot 8 about which the movable edge 6 turns, rings 10 being provided on each alternate folding line and threaded by a cord 9 secured to the movable edge 6 and wound on a vertical spring roller 2. The roller 2 is mounted within a casing 1 on the outer face of which is secured by a batten 4 one edge of the triangular side curtain 3. The stiffeners comprise rods of wood or metal accommodated in pockets formed by stitching lengths of tape to the curtain. Auxiliary short stiffeners 17 are arranged between the main stiffeners. Two sets of rings 10, 13 are provided on alternate stiffeners 16, threaded by cords 9, 12 secured to the pivoted bar 6, the outer cord 9 being wound on a sleeve 2a secured to the spring roller 2 while the inner cord 12 is wound on the roller 2 itself. The cords pass over pulleys 11, 14 mounted in apertures in the batten 4. The pivot 8 is arranged so that the bar 6 is spaced from the batten 4 in the collapsed position to accommodate the folded curtain between them. Integral with the curtain 3 is a toe-piece 3a provided along its vertical edge with rings 18 slidable on a vertical rod 19. A weight 21 in a pocket at the lower edge of the toe-piece causes it to descend as the side curtain is extended, and when the side curtain is collapsed the toe piece is drawn upwardly and bunched at the upper end of the rod 19, which is turned inwardly at 19a. The rings 18 may be removed at the free upper end of the rod 19 and the toe-piece folded into a casing which may be provided to enclose the side curtain. The bar 6 may be the radius rod of the awning. The curtain may be arranged to open upwardly away from the wall.

Abstract: 674,403. Controlling motor vehicles. DAIMLER-BENZ AKT.-GES. Oct. 9, 1950 [Oct. 8, 1949], No. 24654/50. Class 79(v) In a motor vehicle the brake and the motive power controls are so interconnected that each can be operated independently but so that the operation of either effects a positive return of the other or a positive retention in its non-operative position. In Fig. 1, a lever d is mounted on a vertical pivot behind the brake and accelerator pedals and bears against them. It is biassed by a light spring g to rest against the brake pedal a. Full depression of either pedal prevents the other from being actuated. In Fig. 3 the accelerator pedal b is connected by links i, k and a lost motion linkage n to the brake pedal a. The lost motion device permits depression of either pedal singly. In Fig. 4, the brake pedal a 0  is connected a link q to a pivoted cam p against which bears a lever o connected to the accelerator pedal b<SP>1</SP>. The device is particularly useful on vehicles fitted with an automatic clutch.

Abstract: 971,773. Injection moulding. VINATEX Ltd., and FOSTER, YATES & THOM Ltd. June 25, 1962 [July 7, 1961], No. 24658/61. Heading B5A. A method of moulding multi-cellular soles of footwear consists in injecting into a mould a resin together with a blowing agent which have been heated to a temperature above the decomposition temperature of the blowing agent cooling at least part of the mould surface so that the resin in contact with it will set forming a surface layer of non-expanded resin, allowing the mould cavity to enlarge in a controlled manner under the pressure of the blowing agent so that the interior of the resin becomes multicellular, and then leaving to cool. The mould may comprise a movable plate mounted in the mould cavity and controlled by hydraulic, pneumatic or spring means. The hydraulic or pneumatic fluid may also be used to cool the mould. Part of the mould may be replaced by an upper on a last if it is desired to mould the sole directly to the upper.

The worm 3 is connected to a driving motor directly or via a flexible shaft. The torch is supported on the plate 1 by means of horizontal and vertical dovetail guides and is adjustable therealong manually or automatically. The torch is also slant adjustable. Successive torch lifts at successive passes are obtained automatically by a servomotor or, as shown, defined by a stepped chock 25. The centering member 8 has a coned end, to accommodate tubes of different diameter, or, as shown, a slotted spherical end 9, and is slidable between upper and lower positions in which it is retained by a spring-loaded detent 12. The filler wire feed mechanism 27 comprises milled rollers driven by a motor which is energized via contacts sliding on a slip ring on an insulating plate 28. Filler wire may be fed at a rate which is a function of welding rate. The plate 1 is rotatable in casing 5 having a spigot 6 by which it may be supported by the articulated means shown in Fig. 2. In the latter, an arm 37 journalling the spigot 6 is pivotable, in a vertical plane, on a bracket 32 connected, by a link 31, to a sleeve 30 vertically slidable on a column 29. A horizontal arm of the bracket 32 carries an electromagnet 33 serving to attach a circular shoe 34 at positions along an arm 35 rotatable  about the column 29. Horizontal movement of the welder may be effected manually, electrically or mechanically. In operation, the sleeve 30 is adjusted and, by a stop 39, located on the column 29, the centering member 8 is, in its lower position, placed in the workpiece tube end, the electromagnet 33 is energized, and, by a lever 36, the arm 35 is rotationally locked. The centering member 8 is then raised to its upper position to allow lowering of the torch into its working position.
