Title: Improvements in means for admitting supplementary fuel to the carburettors of internal combustion engines
IPC: F02M13/06
Filed: 1949-11-07
Abstract: 726,534. Spray carburetters. DUNSTER, R. W. Aug. 16, 1950 [Nov. 7, 1949], No. 28466/49. Class 7 (3). In apparatus for introducing anti-knock and/ or other supplementary fuel into internalcombustion engines fitted with a carburetter, which includes a separate supply tank for supplementary fuel, a delivery pipe for supplying the supplementary fuel and a control valve adapted to operate automatically to supply variable quantities of the supplementary fuel in accordance with engine requirements, means which admits the supplementary fuel to the carburetter separately from the main supply of liquid fuel in such a manner that the main and supplementary fuels are mixed whilst flowing through the liquid passages of the carburetter prior to being discharged therefrom comprises a ported plug adapted for fitting to the carburetter so as to establish communication between the existing fuel passages therein and the supplementary fuel delivery pipe which is adapted for connection to the outer end of the ported plug. The way in which the invention can be applied to various known types of carburetters is described. Fig. 1 shows how an existing "Ford" (Registered Trade Mark) type carburetter can be modified so that the supplementary fuel can be supplied. The carburetter shown normally employs a power valve which is fitted in a port 12. This is removed and a ported plug 7 introduced in its place a hole 18 being drilled in a cover 17 to accommodate the stem of the plug. The plug is provided with one or more transverse ports 13 adapted to register with an existing byepass passage in the carburetter body. A separate tank (not shown) for the supplementary fuel is provided fitted with a delivery pipe 2. The supplementary fuel is controlled by an automatic control valve 4 which may be acted upon by a spring and manifold pressure. The suction keeps the valve closed until the throttle valve approaches the wide open position. A float chamber 46 is fitted on the side of the valve remote from the carburetter. In a Stromberg type of carburetter a modified form of plug is screwed for example through the wall of the carburetter body so as to be aligned with the discharge end portion of the main fuel passages. The plug may be in two parts so as to form a mixing chamber 22 (Fig. 4) for the main and supplementary fuels. In a "Carter" (Registered Trade Mark) type carburetter the plug is included in place of a removable plug which normally closes the outer end of the discharge end of the main fuel passage. The flow of the main fuel is restricted. The Specification refers to the use of ethyl alcohol and water. Commercial alcohol of 95 per cent. concentration may be used or a mixture of 50 per cent. water and 50 per cent. alcohol. Other supplementary fuels may be used.

Title: An improved method and apparatus for the removal and collection of injurious airborne dusts in the prevention of phthisis and/or tuberculosis and/or other diseases
IPC: B01D47/00
Filed: 1951-12-06
Abstract: 729,818. Removing dust from air by treatment with steam. LUNT, W. R. F. Dec. 4, 1952 [Dec. 6, 1951; Nov. 22, 1952; Nov. 27, 1952], Nos. 28570/51, 29571/52 and 30140/52. Class 55 (2). Injurious dust is removed from air by directing a jet of steam, with which may be mixed smoke, into the air and allowing the air to cool, the steam then condensing on the smoke and dust particles so that they are precipitated. The Figure illustrates the application of the invention to a stone crusher wherein stone which is contained in a hopper 5 is fed downwardly through the crusher and through an enclosure 16 on to a conveyer belt 15. A nozzle 8 directs a jet of a steam-smoke mixture downwardly into hopper 5 so that the abrasive dust formed in the crushing operation is carried down into the enclosure 16 and thence through a duct 13 into an enclosure 14 wherein the steam condenses on the smoke and dust particles to cause their precipitation. The steam is generated in a boiler and passes through a pipe 2 to an ejector-mixer 4 wherein it mixes with smoke withdrawn by the ejector through a pipe 4 connected to the boiler chimney. The smoke provides a cloud of hygroscopic particles upon which the steam easily condenses to form a fine mist which envelopes the dust.

Title: Improvements in or relating to submarine mines
IPC: A46B11/06
Filed: 1928-10-12
Abstract: 324,014. Vickers-Armstrongs, Ltd., and Pratt, H. B. Oct. 12, 1928. Mines. marine.-Relates to submarine mines of the kind provided with two electrical conductors, one called electrode and the other antenna, so designed that when a metal vessel makes contact with one of the conductors an electric cell is formed and a current Bows from one conductor to the other through a moving coil which is situated between the poles of a magnet and is thereby moved and drops a ball between a pair of contacts, thus completing the firing circuit of the mine. According to the invention, the moving coil G, Fig. 3, is geared by pinions G<2>, h to a rotary member H, the rotary inertia of which balances the rotary inertia of the moving coil G, so that this coil cannot be moved accidentally by shock. The ball J is housed in the member H and is dropped through a hole h<1> on to the contacts K, K of the firing-circuit when current flows through the moving coil. Pins h<x> prevent any accidental fall of the ball J. Other contacts k, k, Fig. 4, in the firing-circuit act as a safety device and remain open until the mine A is laid; the pull of the mooring cable F due to the buoyancy of the mine then draws a rod K<4> down, thereby closing the contacts k, k by bridge-pieces K<3>. Simultaneously, the rod K<4> deflects a lever K<6> and removes a bolt K' from locking engagement with the moving coil G. The electrode is in the form af a ring D insulated from the body of the mine.- The antenna may be a cable E attached to a float above the mine or the upper part of the mooring cable F, this being insulated from the mine and from the lower part of the cable; or both antennµ may be provided. A shock absorber may be provided between the two parts of the mooring cable. The upper antenna E may normally be coiled round the float E<1>, Fig. 11, which is made of copper and is held over a guard-plate E<2> on the mine A by two rubber links E', E'. One of these links, namely E<8>, is connected to a shackle e<8x>, which is released by a hydrostat E<9x> when the mine is laid. The antenna E is connected to the circuit within the mine by an insulated shackle E<3> ; and the guardplate E<2> is insulated from both the mine and the float by pads E<6>, E<6x>. This plate protects the circuits from stray current by providing a shunt path of low resistance. The lower antenna F is arranged as described in Specification 324,024.
