Title: Improvements in and relating to gun mountings for aircraft and other vehicles
IPC: F41H5/12
Filed: 1932-03-02
Abstract: 606,874. Aircraft gun mountings. NASH, A. F. March 2, 1932, Nos. 6343, 11304 and 32331. [Class 92 (i)] A gun mounting, particularly for aeroplanes, is constructed in such manner that the gun or the mounting can be moved within certain limits without actuating a servo-mechanism for imparting motion to the mounting, but brings such mechanism into use when moved beyond those limits. In the construction shown, a tubular shield 46 for the gun is pivoted at 46a to a carrier 47 which is linked to the guriner's seat 55 and also to links 49 pivoted on pins 50. A frame 57 accommodating the gunner has rollers 59 engaging in a fixed ring 61 and can be rotated by a servomotor. On the pins 50 are also pivoted a number of sections such as sections 67, 68, 69 of a hood which pivot to and from an operative position, moving in the same rotational direction as the gun is moved. As shown in Fig. 8, the shield 46 has a spherical bearing surface 71 for engagement with a similar surface of the mounting, and has arms 73, 74, with ball ends for actuating slide valves which control the servomotors. A grip 83 near the gun may actuate a master valve in such manner that when the grip is released the parts actuated by the servo-mechanism are locked in position. In a modification, the shield is pivoted centrally on a curved arm whose ends are pivoted on the ring of an aircraft mounting. In a further modification, Figs. 2-4 (not shown), a gun is mounted for training movements on a ring of an aircraft mounting and when moved in training within a flattened tubular shield causes, through linkwork, a slight vertical movement of a further ring which serves to rock linkwork associated with the servo-mechanism.

Title: A method of and apparatus for producing hollow threads, bands, tubes and the like from synthetic thermoplastic materials
Inventor: BEHM WILLY
IPC: B29C48/10
Filed: 1958-02-27
Abstract: Hollow artificial filaments, tubular films and tubes are produced by melt-extruding a synthetic thermoplastic resin through extrusion nozzles, each nozzle being provided with a core in the form of a hollow mandrel, the interior of which communicates with the atmosphere or with a source of a cavity-forming medium at slightly super-atmospheric pressure, the interior of the mandrel being provided with a coaxial tube, the outside diameter of which is less than the inside diameter of the mandrel and the end of which remote from the extrusion orifice is in communication with a duct which, in turn, is in communication with a source of supply of a cavity-forming medium at slightly superatmospheric pressure when the interior of the mandrel is in communication with the atmosphere, and vice versa.  The space between the extrusion orifice and the hollow mandrel may be provided with one or more cross pieces.  Both the interior of the hollow mandrel and the coaxial tube within it may be in communication with the same source of supply of cavity-forming medium so that the latter may be recycled.  Either the hollow mandrel or the coaxial tube may project beyond the inlet surface of the spinneret plate in the form of a chimney in order to facilitate the discharge of the cavity-forming medium into the atmosphere.  The cavity-forming medium may be a gas, a liquid or a freely-flowing particulate solid. Specification 859,325 and Swiss Specification 222,772 are referred to.ALSO:Hollow artificial filaments, tubular films and tubes are produced by melt-extruding a synthetic thermoplastic resin through extrusion nozzles, each nozzle being provided with a core in the form of a hollow mandrel, the interior of which communicates with the atmosphere or with a source of a cavity-forming medium at slightly super-atmospheric pressure, the interior of the mandrel being provided with a coaxial tube the outside diameter of which is less than the inside diameter of the mandrel and the end of which remote from the extrusion orifice is in communication with a duct which, in turn, is in communication with a source of supply of a cavity-forming medium at slightly superatmospheric pressure when the interior of the mandrel is in communication with the atmosphere, and vice versa.

Title: Improvements in apparatus for manipulating kinematograph film
IPC: G03B21/43
Filed: 1922-03-09
Abstract: 195,852. Way, E. J. March 9, 1922. Kinematograph apparatus. - The carrier for the coil of unused films is driven otherwise than bv the film and the used coil carrier is driven from the carrier for the unused film. As shown, the coil of unused film 3 is mounted on a rotating carrier 4, and film is delivered therefrom at the same linear speed as it passes through the gate 2, the means for this purpose being as described in Specification 172,033. The film is taken up on a spool 18 which is driven by chain-and-sprocket gear from a friction wheel 19 driven by the under surface of the carrier 4. The wheel 19 has a radial position which is fixed during operation, but is adjustable to regulate the relative velocities of the carrier 4 and spool 18. The spool 18 tends to rotate at a slightly greater angular speed than the carrier 4, and this tendency is resisted either by a positively driven sprocket or by the tensioning device shown. The tensioning device comprises rollers 27, 38 round which the film passes, the roller 27 having a fixed axis 28, and the roller 38 being' carried by an arm 37 rigid with a lever 33 pivoted at 34. One arm of the lever 33 is weighted and bears on a lever 30 which is pivoted at 31 and carries a pressure roller 29. If the spool 18 runs too fast, the roller 38 is lifted, and the pressure of the roller on the roller 27 is increased, thus increasing the tension in the film.

Title: Radio guiding system
IPC: G01S7/04
Filed: 1946-03-08
Abstract: 623,382. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. March 8, 1946, No. 7319. Convention date, April 2, 1945. [Class 40 (vii)] An aircraft guiding system comprises a plurality of radio transmitters distributed over a given area on the ground and two spaced directional antennµ on the craft, means for moving each antenna to scan a predetermined area with respect to said craft, receiver means for receiving energy from the transmitters and an indicator for producing in response to the received energy a pattern of stereoscopic images substantially simulating the distribution of the transmitters in the scanning field. The radio navigation system for guiding an aircraft during a landing at an airport marked out by low-power short-wave radio transmitters on the same posts as carry the runway lights. described in Specification 601,976 is modified by using two antenna systems mounted one each side of the cockpit. These scan synchronously and their outputs are fed through separate receivers to two separate cathode-ray tube indicators to produce patterns simulating the runway lights, as described in that Specification. The two patterns produced, however, differ slightly owing to the spacing of the antennµ giving rise to them, and if they are viewed one by each eye a stereoscopic impression of depth is produced. A suitable mounting structure for the tubes 50, 50a, has semi-transparent screens 82 and 82a mounted to reflect the luminous patterns on the tubes, one to each eye of the pilot whose forehead may rest against cushion 83 and the fields of vision of whose eyes are separated by partition 84. Besides the picture produced on oscillographs 50 and 50a the pilot also sees the landing area directly through the semi-transparent screens, the picture and the direct view being substantially coincident. In a modification using only one cathode-ray tube 50b, the motor 44 controlling the scanning of the antennµ and the tube screen also operates a switch 97 supplying the tube with signals received alternately by the antennµ 42 and 42a. The pilot views the tube by means of eyepieces 91 and semi-transparent screens 92. A shutter 93, rotating about an axis 94, and also driven by motor 44, obstructs one eyepiece when switch 97 connects one receiver to the oscillograph, and the other, when the other receiver is connected. Thus, the two slightly displaced patterns are viewed one by each eye. Openings 95 and lenses 98 provide the pilot with a direct view in addition to the picture provided by the system.

Abstract: 810,533. Extracting titanium; making titanium alloys. OREGON METALLURGICAL CORPORATION. March 5, 1957 [March 30, 1956], No. 7337/57. Class 82(1) Titanium or titanium alloys are prepared by the reduction of a halide of titanium or a mixture of a titanium halide and one or more other metal halides (for example zirconium, chromium and aluminium chlorides) with an alkaline earth or an alkali metal, the reaction being initiated at the centre of the mixture and spreading outwards. As shown, the mild steel tubular reactor 1 is charged with sodium and end plate 5 and cover plate 7 are placed in position and sealed in a gas tight manner by O-ring 10 and bolts 9. Titanium tetrachloride is admitted through inlet 17 which is then sealed. The reaction is initiated by striking an arc between the titanium electrode 11 and the reaction mixture 14, the current being supplied through bus-bars 15 and 16. The walls of the reactor are cooled to 100‹C. by jets 19 during the reaction to prevent contamination by the metal case 1 and the product, 80 per cent of which is in the form of lumps, is recovered by leaching with water.
