Title: Rocket bomb launching apparatus
IPC: F41F3/06
Filed: 1959-11-19
Abstract: 935,971. Launching rockets from aircraft. R. A. ROBERT, and P. P. MATGE. Nov. 19, 1959, No. 39253/59. Class 9 (2). In apparatus for launching a plurality of rocket bombs from aircraft, comprising a plurality of parallel guide tubes 13, in which bombs 14 are disposed one behind the other, a pivotal deflector 91 is provided for each tube to protect the rear bomb from the propulsive jet of the front bomb and deflect the jet to discharge orifices in a rear wall member 109 of the apparatus. In operation, blast from the firstfired front bomb disengages a bomb-retaining latch 73, 76, which disengagement also allows a pin 70 to rise under the action of a coil-spring 54, Fig. 4, which then displaces an axial tube 50, aligning balls 29 in a sleeve 27 with an annular groove 52 in the tube 50, and releasing an outer tube 31 which is pushed forward by a spring 49, and locked by balls 60, and pivots nose conduits 37 to the open position by links 34. Blast from the first fired rear rocket similarly allows a pin 107, to rise and under the action of a similar coil spring 103 the deflectors 91 are lowered from the paths of the rear rockets. After the last rocket has been fired, a pin 129 rises and permits central tubes 122 and 64 to slide to the rear under the actions of springs 125 and 65, Fig. 5, so that the balls 60 engage an inclined face 62 of the tube 50 and unlatch the tube 31. Restoration during flight of the aerodynamic conditions under control from the aircraft, i.e. the return of the tube 31 to its original position by the firing of an axial cartridge 47, and the restoration of the remainder of the apparatus to its original condition after landing, are described.

Abstract: 904,660. Making ball-bearings; rolling; spinning. EISENWERK ROTHE ERDE G.m.b.H. Dec. 11, 1958 [Dec. 12, 1957], No. 40057/58. Classes 83 (2) and 83 (4). A ball-bearing race 3 is made by forming profiled steel strip into a ring, welding the ends together, and applying radial pressure to stress the ring metal beyond its elastic limit. The profiled strip, Figs. 2, 3 (not shown), which may be formed by rolling, drawing or extrusion, is bent to form an annulus and the ends welded together; the welded joint is then ground. The strip may be formed into a single ring or into a helix which is cut into a number of rings. Double-width profile strip to form two races, Figs. 4, 5 (not shown), may be divided in a lathe after bending and welding. When the strip has a plain flange, Fig. 3 (not shown), the latter is spun over an inner roller 6, Fig. 6, by a pivoted roller 7 or the flange may be rolled by a profiled roller 8, Fig. 7. The ring is then expanded beyond its elastic limit by a device having a number of radial slides which simultaneously planish the ring. Alternatively, the ring may be contracted. The ring is then mounted in a lathe and the raceway is calibrated by a pair of rollers. Two races 1, 3, Fig. 1, are assembled to provide a steering shaft bearing for a motor vehicle. One of the races has a closable aperture through which the balls 4 are introduced.

Abstract: 1,175,314. Vacuum encapsulating electrical conductors. WESTINGHOUSE ELECTRIC CORP. 26 Aug., 1968 [17 Oct., 1967], No. 40603/68. Heading B5A. Electrically conductive means are encapsulated at least partially in a resin by loading a mould containing the conductive means into a vacuum chamber, evacuating the chamber using a first vacuum system, transferring the chamber to a second vacuum system, pouring resin into the mould while retaining the vacuum, with the second vacuum system, returning the vacuum chamber to atmospheric pressure and unloading the filled mould from the chamber. The resin components are mixed under vacuum in a mixing chamber, but this chamber may be under vacuum or at atmospheric pressure when the resin is poured into the mould. Apparatus as shown for carrying out the encapsulation comprises eight vacuum chambers, 18, 20, 22, 24, 26, 28, 30, 32 spaced around the perimeter of a horizontal rotatable carriage 12. The vacuum chambers which are identical in construction and are illustrated by reference to chamber 20 comprise a door 114 operable by piston 120, and locked by ring 116, a gate valve 126 and electrical heater connections 122 and are connected to the manifold 34 of the second vacuum system via pipes 76 and valves 90. The first vacuum system 36 is situated at position II over the carriage and the resin feed mechanism at V, both operating through the gate valve 126. In operation the vacuum chambers are indexed one position at a time by a drive means. The door 114 is open at position I, the mould containing the electrically conductive means is placed therein and the door is closed and locked. In position II, the first vacuum system 36 descends on to the chamber, coupling on to the gate valve 26 which opens and evacuates the chamber. The vacuum system 36 is raised leaving the chamber under vacuum. As the chamber moves to the next position valve 96 opens, connecting the chamber to the second vacuum system operating through manifold 34 and supply pipe 70. In positions III and IV, the mould is maintained under vacuum without processing to ensure maximum removal of entrapped air. In position V, the vacuum chamber is connected to resin supply means via a vacuum-tight link and resin is cast into the moulds. In position VI entrapped air is removed from the resin while the mould is maintained under vacuum, the pressure in the chamber is allowed to return to atmospheric at position VII and the mould is removed at position VIII and transferred to a curing station.
