Title: Improvements in and relating to projectiles
IPC: F42B12/44
Filed: 1954-06-14
Abstract: 767,488. Practice and tracer projectiles and propellent cartridges therefor. LOSFELD, A. June 14, 1954, No. 3919/56. Divided out of 767,487. Class 9 (1). A practice projectile containing a tracer composition comprises a body 70 to which is screwed an arrow head 71 and a tubular tail 72 provided with fins 74. A propellent cartridge 75 is secured in the tail by a plug 76 having an opening 77 to allow passage of the firing pin of a gun. On ignition, the gases from the propellant escape through holes 73 in the tail and pass through openings 78, 79, 80 in the body 70 to ignite a fuze 87 which extends from a nozzle 82 fitted in the end of a tube 81 housing the tracer composition 86. On ignition of the composition 86 the burning gases escape through openings 83, 84, 85 in the tube 81 and through the openings in the projectile. The composition 86 may generate smoke or may be an illuminant and may be arranged to produce different colours e.g. white over the first part of the trajectory, green for the second part and red for the last part. Gas-check rings 88 are formed in the body 70. In a modification, Fig. 2, intended for use with rifled bore guns, the projectile extends from a cartridge case 95 which holds in position a resilient skirt 90 replacing the rings 88. The head of the projectile is in two parts, the part 92 being filled with a solid or liquid composition, which will give a coloured trace upon impact e.g. with armour plate. Relay charges may be placed between the tail fins. The propellent cartridge, Fig. 3, has a cardboard casing 101 impregnated with paraffin wax and is fitted with a varnished brass end cap 102. A cardboard wad 103 surrounds a detonator 104 and a tube 105 of cartridge paper is filled with " Ballistite," Registered Trade Mark, covered by a glazed cardboard disc 107 and a washer 108 of metal, e.g. lead. Above the washer is a felt wad 109 on to which the casing is turned. The cartridge shown in Fig. 4 contains a smoke-generating charge 117 and the mouth of the case is reduced to hold a tube 113 filled with compressed black powder from which extends a fuze 115. At the inner end of the tube 113 is a conical space which improves the ignition of the composition 117 by the black powder 114. A modified cartridge, for discharging smoke when the projectile hits the ground, contains a smaller delay charge 114 which arms a spring-stressed firing pin, so that on impact the pin strikes a detonator at the bottom of the tube 113 to fire the tracer composition. The firing pin may have a flattened end to anchor it in the delay charge.

Title: Improvements in or relating to rotary deformable tube machines operable as pressure pumps, motors, compressors, or vacuum pumps
IPC: F04B43/12
Filed: 1966-01-28
Abstract: 1,122,275. Rotary pumps and motors. E. MALBEC. Jan. 28, 1966 [Jan. 30, 1965; Jan. 12, 1966], No. 3969/66. Heading F1F. A rotary deformable tube pump or motor comprises a cylindrical cage rotatable about a central axis and having a plurality of freely mounted rollers distributed around its periphery against which a deformable tubular element is applied with sufficient contact pressure so that any fluid passing through the tube by successive compressions and expansions of the fluid is either pumped through the tube or creates a driving torque to rotate the cage. There may be a plurality of deformable tubular elements surrounding the cage connected either in series or parallel. A number of pumps or motors may be coupled together on the same or different shafts. In one embodiment, the deformable tubes are made of elastic material. In another embodiment, the tubes are made of non-elastic material, e.g. thin stainless steel sheet, which when the cage is mounted in a fluid-tight evacuated casing permits the restoration of the tubes between rollers to their normal cross-section due to the pressure difference internally and externally of the tube. One of the tubular elements may be used to evacuate the casing. The tubular elements may have a conical section in the longitudinal direction with the ratio of conicity sufficiently high to obtain a progressive variation in pressure of the fluid and automatic cooling of the elements.

Title: Improvements in and relating to systems of electrical distribution
IPC: H02M7/44
Filed: 1925-02-13
Abstract: 230,805. British Thomson-Houston Co., Ltd., (Assignees of Prince, D. C.). March 14, 1924, [Convention date]. Vacuum apparatus, arrangements of. - Alternating current is obtained from a direct-current source by an arrangement of electron discharge valves and transformers in which current from the direct-current source is supplied to each primary winding of the supply transformer through a pair of oppositely-connected valves, one of which is controlled by grid potentials derived from the secondary winding of the transformer, the other being controlled by grid potentials derived from both the primary and secondary windings. In the arrangement shown, starconnected primary windings 1, 2, 3 of the supply transformer are earthed at one end through an inductance 4, and their other ends are connected respectively to the anodes of the valves 5, 8, 9 and to the cathodes of valves 6, 7, 10. The direct-current supply leads 11, 12 are connected respectively to the anodes of the valves 6, 7, 10 and to the cathodes of the valves 5, 8, 9. The alternating current output leads 16 are taken from the delta-connected secondary windings 13, 14. 15 of the supply transformer from which tappings 19, 20, 21 are taken for controlling the grid potentials of the valves. These tappings are connected to the primary windings 18 of a. transformer 17 which has two sets of secondary windings 22, 23, 24, and 27, 28, 29. To the first set of secondary windings 22, 23, 24 are connected the grids of the valves 5, 8, 9, the cathodes of which are at a steady potential, viz., that of the negative side of the direct-current source. Since the cathodes of the valves 6, 7,. 10 are connected to the primary windings of the supply transformer and, consequently, have oscillating potentials, in order to give to their grids potentials which bear the same relation to their cathodes as in the valves 5, 8, 9, the grids of the former group of valves are connected to the second set of secondary windings 27, 28, 29 of the transformer 17 through the secondary windings 32 of a transformer 30, the primary windings 31 of which are connected to the primary windings 1, 2, 3 of the supply transformer. In, order to render the grid excitation of the two groups of valves symmetrical, resistances 25 and inductances 26 corresponding in value to the resistance of the windings 32 are provided in the grid circuits of the valves 5, 8, 9. To maintain constant the current drawn by each group of grids, the star points of the secondary windings of the transformer 17 are connected respectively to earth and to the negative side of the direct-current source through the windings of a transformer 35 and resistances 36, 37. The cathodes of the valves 6, 7, 10 are heated by current taken from sections of the windings 1, 2. 3 of the supply transformer, the cathodes of the valves 5, 8, 9 being connected in parallel across the secondary winding of a transformer 38, the primary winding of which is connected to one of' the primary windings of the transformer 17.

Title: An improved method of and apparatus for generating a reducing gaseous mixture controlled and continuous at low temperature and for commercial utilisation of the gaseous mixture
IPC: C10J3/00
Filed: 1938-02-10
Abstract: 514,874. Gas-producers ; retorts ; furnace atmospheres. JOHNSTON, G. G. Feb. 10, 1938, Nos. 4177, 20560 and 20561. Void. Convention dates, Feb. 10, 1937, July 12, 1937, and Oct. 29, 1937. [Classes 51 (ii) and 55 (i)] Reducing gases obtained by the action of superheated steam on incandescent fuel in a gas-producer are passed into a reducing chamber adjacent the producer, from which chamber they. are led to exhaust conduits. By this means shale and coal are distilled for oils, cocoanut is dehydrated, or arsenic is removed from arsenical ores. Steam generated in a boiler 13 passes by pipe 20 to a superheating coil 21 in the crown of a gas producer 14, and dry steam is led by distributing pipe 22 and nozzles 27 in the sides of the producer, air entering through annular openings 29 which are normally closed. A reducing furnace 31 is separated from the fuel bed of the producer by a wall 35, and communicates with a longitudinal exhaust passage 36 by ports 37 controlled by dampers 38. The material to be treated is charged on to trucks 91 running on rails 41. Three outflows 43, 44, 45 communicate with passage 36, and have steam scavenging pipes 47, 48, 49. Outflows 43, 45 lead to treatment chambers 69, 72 respectively, and 44 leads to a chimney stack 63 into which residual gases from the treatment chambers pass. By operation of a damper 65, these gases may be diverted to a pipe 64 leading to condensing apparatus, being assisted by a fan 67. A quenching chamber 79, with a steam supply from pipe 83 and the boiler 13, is arranged so that the truck containing the charge is run on rails into the chamber which is closed by gastight doors 80. In practice, when the coke in the producer has been brought to a red heat, openings 15, 16, and 28 are closed, and superheated steam from coil 21 admitted through pipes 24, the temperature of the reducing gases being determined by the depth of the fuel bed, and by the admission of some air. The pressure in the reducing chamber may be raised by partially closing dampers 38 or 58, 59 and 60, and a continuous flow can be maintained for six to eight hours. The quenching chamber is only used for those residues which are combustible when removed from the reducing chamber. For the activation of carbon, the material, such as cocoanut shells; is charged into cylindrical retorts 99 arranged in rows, Fig. 7, steam being admitted through a perforated pipe 113 extending through each retort, and the distillates removed through pipes 103 and a manifold 104. The steam is superheated by passage through pipes 108.

Title: Improvements in or relating to dynamo electric generators
IPC: H02J7/16
Filed: 1928-02-11
Abstract: 313,468. Debenham, W. R. Feb. 11, 1928. Exciting.-A continuous current generator G has in the circuit of its field winding Z the armature R of a regulating motor, the field winding E of which is in series with a controlling battery B across the generator, and means are provided to prevent the motor reversing its direction of rotation when the generator voltage is less than the battery voltage. In operation, the reverse current cut-out C closes when the voltage of the generator is equal to the battery voltage, and no current flows through the winding E when the voltages are equal. If as the result of a change in speed or load, the generator voltage tends to increase, a charge current will flow through the battery, causing a voltage to be induced in the armature R of the regulating motor and so reducing the current in the field winding Z of the generator. The relay X is arranged to short-circuit the field winding E of the regulating motor when a small discharge current flows to prevent reverse rotation of the motor. Instead of short-circuiting the motor field winding, reverse rotation may be prevented by fitting the motor shaft with a ratchet or other free-wheel device. The winding E may be shunted by a resistance whereby the battery charge current may be adjusted.

Filed: 1944-06-09
Abstract: 579,296. Cable brakes. BEDFORD, C. A. June 9, 1944, No. 4422. [Class 78 (iii)] [Also in Group XXXIII] Brakes for equalising the tension of two cables, such as support lifeboats, painters, cradles, etc., comprise two fairleads 26, one for each cable. The fairleads are journalled at 28, 29 about a transverse axis, so that when turned slightly out of truth they impart a kink to the cable and exert a braking effect thereon. The fairleads 26 are carried in a frame 14 suspended by hanging links 11, and accommodating pulleys 19 about which the cables are rove for attachment at their free ends to bollards 42. Opposing springs tend to keep the frame 14 in its central position, but excess tension in one cable 43 draws the frame 14 to one side or the other and causes arms 31 extending from the lower journals 29 of the fairleads 26 to abut against stationary pins 30 and so turn the fairlead slightly. The arms 31 have off-set ends to increase the rotary effect at extreme differences of tension. A pin 33 may be inserted through the frame 14 and a stationary block 34 to put the brake out of action when desired. The springs may bear against an adjustable abutment so that their effect may be biassed to produce different tensions in the cables.

Title: Improvements in or relating to apparatus for electrically operating railway and tramway points and for analogous purposes
IPC: B61L11/00
Filed: 1936-02-14
Abstract: 448,841. Operating railway and tramway points and signals. QUILLIAM, L., and FOREST CITY ELECTRIC CO., Ltd., 4, Longford Road, Stretford, Manchester. Feb. 14, 1936, No. 4446. [Classes 104 (i) and 105] Apparatus for electrically operating railway &c. points, switches &c. in current conductors, and signals, comprises a line contactor adapted to be engaged by the current collector, and consisting of two insulated strips 4, 5, so arranged that the point-operating coils 38, 39 are not energized until after the collector has left the contactor. When the collector engages the contactor with current off, a small current passes from the conductor 3 through wire 6, relay coil 8, wire 7, strips 5, 4, fuse 28, quick-action relay 20, slow-release relay 25, resistance 31 to earth 30. Armature 17 is lifted off contact 19, so preventing current from passing from the line 3 to the point operating coil 38. When the collector leaves the contactor, the relays 20, 25 are de-energized, armature 17 returns to contact 19, but armature 23 is held for a short time, so that contact 21 still engages contact 27 of a blown out coil 15, permitting current to pass from 3 through 19, 17, 18, 21, 27, 15, 14, 10, 9, 11, 36 to coil 38 to operate the points. If the collector engages the contactor with current on, a heavy current passes through the relay 8 and the vehicle motor to earth, moving armature 9 over to contact 13. At the same time a small current passes as before through relays 20, 25 to earth 30 moving armature 17 away from contact 19, and lifting armature 23 to permit contact 21 to fall on 27. When the collector leaves the contactor, relays 20, 25 are de-energized, 17 falls on to 19, and current passes from 3 through 16, 19, 17, 18, 21, 27, 15, 14, 10, 9, 13, 37 to coil 39 to operate the points. Armature 23 then falls, breaking contact between 21 and 27, and then the slow action coil 12 releases armature 9.
