Title: Improvements in and relating to devices for the sparkless disconnection of an inductive resistance
IPC: H01H9/54
Filed: 1921-10-01
Abstract: 169,721. Krupp Akt.-Ges., F. Oct. 4, 1920, [Convention date]. Addition to 158,873. Sparking-preventing devices.-Relates to a development of the method described in the parent Specification for sparklessly breaking an inductive circuit A and for destroying its residual magnetism. The Figure illustrates the position of the switches when no current is flowing. The main circuit is made or broken by moving the handle J to the left or right. On make, the spring h moves the rod H upwards and bridges the gap h', h', the coil h<2> then hnlding on. On break, the spring d<2> forces up the rod D and completes circuits C and E respectively. The circuit E energizing the coil b<3> raises the rod B and actually breaks the main circuit, and an induction current passes from the circuit A through the circuit C so that sparking is prevented. The rod H, however, being now released, a circuit is completed, viz., positive, F, A, G, E, negative, which ensures a current passing through the inductive circuit A to destroy its residual magnetism. The rod D now drops breaking circuit E to allow the rod B to drop so that the position illustrated is restored.

Title: Improvements relating to the manufacture of mosaic screens
IPC: H01J9/12
Filed: 1945-10-06
Abstract: In a process for the manufacture of a mosaic screen the material which is to form mutually insulated conducting elements is deposited on to an insulated carrier through a stencil which is held in contact with the carrier by electrostatic or magnetic force during the deposition.  A mosaic of antimony or bismuth may be deposited on a carrier plate within a sealed and evacuated cathode ray television tube through a mesh of fine silver, nickel or aluminium wire attached at one edge to a rod.  An electric potential is set up between the mesh and the carrier plate by which the former is pulled into close contact with the latter. After deposition is complete the electric potential is removed and the mesh may be rolled up on the rod and removed through a previously sealed side tube.  Magnetic force may be used if the mesh is made from magnetic material.  Alloys of antimony and bismuth with palladium, rhenium, platinum, iridium and osmium may also be deposited and the elements activated to photo sensitivity by subjecting them to the action of an alkali metal.

Title: Polymerization of ethylene
IPC: C08F10/00
Filed: 1954-09-14
Abstract: In a continuous process for the polymerization of ethylene in a reaction zone having a ratio of length to width of at least 15 : 1, under pressures between 1000 and 2000 atmospheres, at temperatures between 110 DEG  and 275 DEG  C., and in the presence of a free radical producing catalyst, a substantially uniform temperature profile with time is maintained by the introduction of an inert liquid in a primary steam to preheat the ethylene to approximately initiation temperature and in secondary streams at intermediate points together with the catalyst at temperatures below the effective free-radial producing temperature.  In an example, polyethylene is compressed in compressors 3, 5, and a preheated mixture of inert solvent, e.g. benzene and chlorobenzene, together with water introduced from tanks 11, 22 respectively, and a catalyst, e.g. t-butyl peracetate, in water added as a secondary stream from tank 22. secondary streams are added at temperatures below the effective free radical producing temperature of the catalyst at intervals at points 18, 19, 20 along the converter to <PICT:0756813/IV(a)/1> maintain a substantially uniform temperature profile with time. Saturated hydrocarbons, e.g. methane, ethane, propane and butane, may also be introduced from tank 23.  The polymer is discharged to a separator 7, the gaseous products removed and the polymer precipitated as a slurry in water which is then removed and the product extruded and chipped.  Catalysts such as hydrogen peroxide, persuccinic acid, lauryl and diethyl peroxides and azo-type catalysts may also be used.  The product has a density of 0.92 to 0.93. Specification 626,155 is referred to.

Title: Toy gun
IPC: F41C3/08
Filed: 1960-07-29
Abstract: 931,715. Toy guns. LOUIS MARX & CO. Ltd. July 29, 1960 [April 8, 1960], No. 26576/60. Class 132 (3). A toy gun, e.g. a machine gun or pistol, has noise making means comprising a hammer which may strike a diaphragm or caps on an anvil and which is actuated through cam means forming part of gearing by pulling a tape, strap, cord, chain or the like. Fig. 1 shows the mechanism of a toy machine gun and, as can be seen, pulling a tape 12 wound on a drum 52 rotates gears 34, 35, 38 which intermittently rotate an anvil 70 through a pinion 80 and Geneva gear 40 as described hereafter in relation to Fig. 9. The anvil 70, by means of sprocket teeth 72, draws a perforated strip of caps from a roll 60 on a shaft 62 projecting from the side of the gun, the caps being fired on the anvil during its stationary intervals by a hammer 42 pivoted at 48, urged upwardly by spring 50 and actuated by a cam 44 and cam follower 46. The parts forming a cap magazine have a pivoted cover 14. Spent caps are removed from the anvil 70 by a stripper spring 74. A spring 56 is secured to the tape drum 52 for rewinding the tape after it has been pulled out and, to prevent the gun operating during the rewinding, shaft 28 of gear 36 is mounted in slots at 58 so that it can ride upwardly and the gear idle. As an alternative one-way clutch mechanism there may be a ratchet between the drum 52 and gear 34. Fig. 9 shows a cap firing gun not having a rewind spring and wherein a cord drum 116 is external of the gun casing so that the cord after being pulled can be rewound by hand. Intermittent rotation of an anvil 82 by a Geneva gear 84 is by a pin 88 which moves counter-clockwise, enters a slot 90 of the Geneva gear, turns it to the position 92 and then leaves the gear, the latter being held against further rotation by mating with a curved surface 86. A pivoted hammer 96 spring urged by end 128 and having a cam follower 94 engaging a cam 100 is provided as in the previously described embodiment. An arrangement is described wherein the tape is secured to a gun belt so that it is pulled to actuate a gun when the gun is drawn from a holster. In a further arrangement, the gun is pivoted to a gun belt so that it hangs muzzle downwards. Pulling the cord downwards pivots the gun, until limited by a stop in which position the muzzle points forward, and fires the gun.

Abstract: 503,422. Electromagnetic relays. BENDIX AVIATION CORPORATION. Oct. 5, 1937, No. 27003. Convention date, Oct. 6, 1936. [Class 38 (v)] [Also in Groups XXXVIII and XX] In a system for periodically operating a signal transmitter through the intermediary of a solenoid 52 for repeating the indications of a compass alignment of the member 40 with the member 47 through periodic operation of the solenoid is produced by a relay consisting of a contact pile 61 operated by the armature 60 of a magnet 58 having two parallel coils 67, 68 of different resistances. As soon as the relay is de-energized, solenoid 52 is energized and current flows through coil 68 and instantaneously through coil 67 to charge a condenser 72. Under these conditions coils 68, 67 oppose each other and armature 60 remains unoperated, but when the condenser current weakens, coil 68 operates armature 60 to actuate the contact pile and thereby de-energize the solenoid 52 and close a series circuit over the coils 68, 67 for discharging the condenser. During discharge, the armature is maintained attracted but when discharge ceases the armature drops away and the cycle is recommenced. A variable resistance 76 is connected in parallel to the discharge circuit so as to vary the rate of discharge.

Title: Improved construction of stay or strut for hinged or folding articles
IPC: A45C13/34
Filed: 1929-09-07
Abstract: 331,753. Greenman, H. Sept. 7, 1929. Stays.-A stay 1 for hinged lids is pivoted to a bracket 3 at one end and carries a rotating member 5 at the end working in conjunction with a slot 9 of uniform width in a plate 7 secured to the body of the article. When the lid is opened the hub 6 of the member 5 rides along the slot 9 until a corner of the member 5 contacts with a stop 11; this causes a partial rotation of the member so that a slight lowering of the lid causes the stay to become locked by engagement of an opposite corner with the stop 10. To close the lid it is moved upwards till a corner of the member 5 engages the stop 11, causing the member to be partly rotated so that the opposite corner points away from the stop 10. The closing of the lid completes a halfrotation of the member 5 which slides along the plate 7 under the stop 10. In a modification, the member 5 is pivoted on the plate 7 and a slot 14 is formed in the stay 1. Fig. 3 shows the position for sustaining the lid. To close the lid the lid is moved upwards till the projection 11 partly turns the member 5 as before, so that it can move under the stop 10 and permit the end of the stay to clear the shoulder 13.

Title: Compression-ingnition internal combustion piston engine
IPC: F02B23/06
Filed: 1974-06-20
Abstract: 1448797 Combustion chambers BARKASWERKE VEB 20 June 1974 [25 June 1973] 27376/74 Heading F1B A compression ignition internal combustion engine comprises a rotationally symmetric combustion chamber 2, Fig. 2, having an impact surface 31 on to which fuel, injected via a nozzle, impinges, the fuel being deflected from its original path resulting in a higher fuel to air ratio and consequently greater ignitability for starting the engine. The diameter of the combustion chamber which is formed in the top of piston 1, varies as shown in Fig. 2, the surface 31 being situated in a plane passing through the largest diameter and being formed on a pin 311 embedded in the wall of the combustion chamber. Means is provided for creating an air vortex within the combustion chamber, the vorticity of which increases with the engine speed. At low engine speeds, i.e. on starting, the vorticity is insufficient to deflect an appreciable portion of the injected fuel away from surface 31, the fuel therefore strikes the surface and is deflected back along its path resulting in a richer mixture for starting. At the engine's operating speed the vorticity is sufficient to cause a portion of the injected fuel to be deflected away from surface 31 thereby reducing the richness of the mixture for normal running. The impact surface 31 may instead be supported by an arcuate ramp (312) Fig. 3 (not shown), which is integral with the combustion chamber wall. In an alternative embodiment, Fig. 6, the impact surface is formed on the head of a pin 321 threaded into the combustion chamber wall near its open end, a portion of the fuel impinging upon the surface at a substantial angle of incidence and being deflected toward the axis, resulting again in a richer mixture for starting. At operating speeds, the deflected fuel is maintained in a vortex in the proximity of the combustion chamber opening where it has minimal effect on the richness of the mixture. In this embodiment, the proportion of fuel deflected by the impact surface may be varied by varying its distance from the combustion chamber wall.
