Title: Improvements in and relating to insulated electrical conductors
IPC: B29C63/00
Filed: 1939-09-01
Abstract: 534,160. Conductors. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 1, 1939, No. 25072. Convention date, Sept. 1, 1938. [Class 36] A conductor is insulated by applying a wrapping of super-polyamide, heating the wrapping to form a continuous coating, and hardening the coating. A wire 1 is drawn from a supply spool 2, by means of a driving capstan 3, through a covering machine 4. A flyer 5, withdraws the super-polyamide in thread, yarn, tape, or other form from a spool 6, and wraps it round the wire 1, the covered wire then passing through a nose piece or polisher 7 and a tube 8 heated by electrical heating elements 9 or otherwise. The temperature of the tube and the rate of travel of the wire are so adjusted that the superpolyamide melts and flows to form a smooth continuous film on the wire. After leaving the heater tube the wire is allowed to cool to harden the coating and then passes over a guide sheave 10 to a take-up spool 11. The super-polyamide may be prepared as described in Specifications 461,236 and 461,237, [both in Group IV], and is preferably a reaction product of hexamethylene diamine and adipic acid. In an example a wire 0.010 inch in diameter is covered with this material and traverses an enamelling tower at a speed of 12 feet per minute and a temperature of 310‹ C. The heating may alternatively be effected by passing a current through the wire. Covered wire may be wound into a coil, with or without thin sheets of super-polyamide or other insulating material between the layers, the entire coil being then heated either in an oven or by electric resistance heating so as to form a mass of solid super-polyamide in which the windings are embedded. The complete coil may be covered with a fabric or a smooth surfaced continuous sheet of super-polyamide. For example it may be formed of a combination of asbestos, spun glass, mineral wool, or other fibrous inorganic material and super-polyamide as described in Specification 532,487. Specification 534,158, [Group XXXV], also is referred to.

Title: Method and apparatus for simulating a ballistic trajectory
IPC: F41G3/28
Filed: 1974-06-06
Abstract: 1424299 Method for the simulation of a shooting or projection process KRAUSSMAFFEI AG 6 June 1974 [2 Aug 1973] 25082/74 Heading F3C  Method for the simulation of a shooting or projection process, with use of artificially generated flight path signals for the representation of the flight path of an imaginary missile over a terrain, wherein the measurement direction of a range finder E, Fig. 1, is controlled successively to individual loci Fi of the flight path and the measured value thereupon ascertained of the momentary distance of a reference point B from an object or terrain point Gi (measured distance BGi) situated in the measurement direction is compared with the measured value of the ideal distance, ascertained on the basis of the flight path signals, between momentary locus Fi of the flight path and the reference point B (ideal measured distance BFi) and the two measured values are processed into a momentary control signal for the ascertaining of the point of intersection A of the flight path with the terrain. In the X-Y-Z co-ordinate system shown, terrain G is arranged in relation to reference point B which represents the position of a marksman. The latter selects the type of missile and uses an aiming apparatus (not shown) to set the initial direction of flight path F, this being represented in the form of artificial flight path signals produced by a computer (not shown) for example. The range BFi between the reference point B and the respective locus Fi of the flight path F can constantly be ascertained. The range finder E is positioned relative to the reference point B. The measurement direction of the latter is orientated by a control appliance (not shown) to any desired loci Fi (F1, F2, for example) of the flight path F. The measurement direction beam of the range finder E is controlled to the relevant flight path locus Fi and the distance EGi from an object or terrain point Gi is measured and the distance BGi between point B and point Gi is determined. Inequality or equality between the distances BGi and BFi is ascertained and, if equality applies, a signal is generated to mark a represented intersection point A of flight path F, the surface of the terrain G and momentary measurement direction beam of the range finder E. It is advantageous if the point B and the range finder E and preferably the starting point S of the flight path F coincide as shown in Fig. 2. The measurement direction beam of the range finder E is pivoted in a vertical plane containing the flight path F and scans the terrain G along the track T in the direction of the chord BFi. The method can also be used in the case where a terrain elevation U, Fig. 3, obscures the view of the marksman from the last part of the flight path F before impact. The apparatus used by the method is represented by block circuit diagrams, Figs. 4a, 4b (not shown).

Title: Improvements relating to the driving of dynamo-electric generators
IPC: H02P23/16
Filed: 1938-08-26
Abstract: 502,397. Steam turbines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 26, 1938, No. 25141. Convention date, Aug. 27, 1937. [Class 110 (iii)] [Also in Group XXXV] An auxiliary generator b for use in con. nection with steam power plant is driven normally through an overrunning clutch d by a main engine a, but when the main engine is out of action or running at low speed, a speed dependent device such as a governor f brings into operation an auxiliary engine c. The auxiliary engine c is constantly rotated, but the valve g admits steam only when the speed falls so that the drive by the auxiliary engine is at a lower speed than the main drive. In a modification, the speed is arranged to be the same in both operations by adjustment of the governor and by the provision of a rapidlyopening valve in the auxiliary engine supply actuated by the regulating gear of the main engine.

Abstract: 754,062. Band clips; releasable joints; bolts. THOMPSON PRODUCTS, Inc. Aug. 30, 1954, No. 25148/54. Classes 44 and 89 (1). [Also in Group XXVIII] A device for coupling parts E, A of machinery, e.g. an accessory such as an oil pump, dynamo or starter to an engine comprises two rings 11, 12 each attached or adapted to be attached to one of the parts to be coupled, a split locking band 13 carried in peripheral grooves 24 on radial fingers 23, projecting from one of the rings 11 and adapted to engage inclined faces of lugs 26 carried by interfitting fingers 25 on the other ring 12 and a draw bolt assembly 14 by which the. locking band may be tightened to exert a wedging force on the lugs 26 and lock the two rings together, the lugs 26 being such that the two rings can be engaged and disengaged without removal of the locking band from the grooves. This is achieved by making the height of the lugs less than that of the grooves so that by slackening-off the draw bolt assembly the band 13 is expanded radially sufficiently to clear the lugs without becoming detached from the grooves. As shown, the rings 11, 12 are bolted to the parts E, A with the interposition of gaskets, but can be made integral if desired. The ring 11 is located on the part E by a tapered lip 11a and the ring 12 is located on the part A by a flange A<SP>1</SP> on the part A and in the ring 11 by a flange 12a which fits. in the bore of the ring 11 with a sealing gasket 19 between the two rings. Aligned passages 20, 21 are provided in each ring for the passage of lubricant between the parts E, A. To make the inter-engagement of the fingers easy, each has tapered portions. The locking band is secured to brackets 30, 31, against one of which a bolt 34 bears, the other being engaged by a nut 36 for the bolt. A rubber ring 41 on the bolt shank prevents rotation of the band on the ring 11. The bolt head is apertured so that it may be secured to its bracket by a sealing wire 40.

Title: Improved process for the extraction of oxygen from air
IPC: C01B13/08
Filed: 1946-08-23
Abstract: <PICT:0628572/III/1> In a process for extracting oxygen from air which comprises contacting air with a solid oxygen acceptor, such as metals, e.g. silver or oxides of metals with more than one valency, e.g. oxides of manganese, barium, or chromium, which may be alone or mounted on carriers, e.g. pumice, clays or silica gel, to form a solid oxygen compound giving oxygen on heating, the oxygen acceptor and oxygen compound are maintained in dense fluidized beds of finely-divided solids in oxidation and dissociation zones fluidized by air and liberated oxygen with or without steam or natural gas, respectively, and the solids are circulated between the zones.  The heat of dissociation may be supplied by external heating, by conducting a heat liberating reaction in contact with the oxygen compound, e.g. by combustion of solid, liquid, or gaseous fuel such as hydrogen, methane, natural gas, gas or fuel oils, or finely-divided coal, coke, or wood, by adsorption of steam on a finely-divided solid adsorbent such as silica gel admixed with the oxygen acceptor, or by a combination of these methods.  Oxygen may be separated from the mixture of oxygen, water vapour and carbon oxides or a hydrogen-containing synthesis gas may be produced by reacting the mixture with methane with or without water separation.  In Fig. 1, purified air is passed into p  vessel 5 at 400-1200 DEG  F. through pipe 6, while finely-divided barium monoxide to which lime may have been added to prevent sintering is continuously added through 8, and is converted to peroxide which is withdrawn from vessel 5, and stripped with steam or oxygen in standpipe 14; the nitrogen passing out at 10.  The peroxide passes through a plurality of tubes 17 in furnace 15 to regenerator 20 at 100-400 DEG  F. above the temperature in vessel 5, while the oxygen passes through dust separator 21 to boiler 23, may be cooled and compressed and used as fluidizing gas.  The barium monoxide passes back through cooler 30 to vessel 5 and may be replaced as required with fresh oxide.  The adsorption may be carried out in several stages, and alternative apparatus is also described.

Abstract: 1,185,974. Navigating apparatus; indicating apparatus; odometers. AVIATION ELECTRIC Ltd. May 28, 1968 [May 31, 1967], No.25403/68. Headings G1F, G1J and G1K. A navigation system for a vehicle comprises a flux gate compass providing indication of the direction of travel, the compass being compensated for the disturbing effects of the mass of the vehicle, and a drive responsive to vehicle speed and coupled to a resolver to provide signals indicative of distance travelled from a starting point in two resolved directions e.g. N-S and E-W. The system is described in connection with land vehicles, the flux gate compass and vehicle speed drive being used to provide angular heading and distance travelled inputs to a ball resolver from which the N-S and E-W distance travelled signals are derived preferably in the form of pulses from suitable pulse generators. An indicator is provided for vehicle heading, and vehicle position may also be indicated and/or recorded using a vehicle position plotter unit with a map of the area in which the vehicle is travelling. The flux gate compass is compensated for the effects of the mass of the vehicle, these effects being divided into those due to the actual vehicle and those due to the vehicle heading. It is shown that compensation can be effected by the use of three electromagnetic dipoles aligned respectively along the horizontal vehicle axis, a horizontal axis at right angles thereto and the local vertical, the strengths of the dipoles varying with vehicle heading under control of a resolver servosystem having an input from the compass. The compensation system is derived for a particular vehicle and is then generally applicable to other vehicles of the same type. Details of the theory and practical considerations of the compass compensation are given in the specification. Also discribed is an embodiment in which the flux-gate compass is replaced by a magnetic sensor in the form of two coils positioned 90 degrees with respect to each other end mounted for rotation about a common vertical axis, the sum of the signals from the two coils being resolved to find the direction of the meridian.
