Title: Improvements in carburettors for internal combustion engines
IPC: F02M5/12
Filed: 1919-05-07
Abstract: 141,205. Veulle, F. H. de. May 7, 1919. Spray carburettors.- A mixture of fuel and air is supplied to a stationary Venturi, streamline or other shaped air passage A controlled at both sides of the orifice F in the wall of the passage by a single sleeve valve J. In one form, the passage A is bored in the top of a hollow stem B dipping into the float chamber C, and the fuel passes up a channelled nipple H<2> in the stem B and mixes with air entering at H<5>, the mixture. then passing a spraying-head H<6> to the port F. For slow running, a duct H' leading from the space H<4> may communicate with the gas passage on the engine side of the throttle. In another form, the mixture is formed in a chamber within the float chamber and is led therefrom by one or more passages to one or more gas passages A. The gas passage A may swivel about a hollow arm along which the mixture flows. In another form, the throttle chamber and shaped passage are arranged by the side of the float chamber, and the mixing-chamber is arranged between them. In another form, the fuel passes up a hollow stem fitted in a sleeve surrounded by the float, and mixes with the air in an annular space between the rod and sleeve. In another form, air passes down a hollow rod and through fuel rising through passages in alinement with the rod. The air supply may be controlled in this form by adjusting the air-tube vertically, or by fitting an adjusting-screw in the opening at the top. Specification 10649/14 is referred to.

Title: Electro-magnets
IPC: H01F7/18
Filed: 1939-04-14
Abstract: 523,438. Electromagnetic switches, CONTACTOR SWITCHGEAR, Ltd. April 14, 1939, No. 11397. Convention date, April 15, 1938. [Class 38 (v)] An electromagnetic contactor has a main excitation winding A fed by alternating current and an auxiliary retaining winding C fed by direct current which may be obtained by rectification of the alternating current. The magnet is adapted to attract an armature 4 pivoted at 12 and slug rings 16, 17 are also provided to prevent momentary disappearance of flux. Fig. 5 shows one circuit arrangement. An A.C. supply 18 feeds the primary of a transformer 20 the secondary of which supplies through a rectifier 21 direct current to a relay 23 when a switch 22 is closed. The relay 23 thereupon closes contacts 24 which connect the supply 18 to the main winding A of the contactor which then operates to close its main contacts 25, to break at 27 the circuit to the relay 23 and to make at 26 a rectified-current circuit to the auxiliary winding C. The opening of the relay circuit 23 causes the breaking at 24 of the circuit to the main winding A. Thus the winding A closes the contactor and the winding C retains it.

Title: Improvements in or relating to machines for manufacturing metallic bellows
IPC: B21D15/06
Filed: 1944-06-15
Abstract: 578,065. Corrugating. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. June 15, 1944, No. 11458. [Class 83 (iv)] A machine for the formation of metallic bellows comprises a mandrel over which a tubular metal blank is mounted, a roller or rollers mounted on a movable support adjacent the mandrel and moved automatically into co-operative relationship with a roller or rollers on the mandrel to shape the bellows corrugations and automatic means adapted to operate as each series of corrugations is completed, to feed the workpiece along the mandrel. The machine comprises superimposed base-plates 4, 5 and 6 supported by standards 7 and each carrying similar tube corrugating mechanism. Above the lower base-plate 6 is a mandrel 1 mounted in a fixed bearing 10a at one end and in a removable bearing at the other end and adapted to be driven through a clutch 9. A tube 1a to be corrugated is placed over the mandrel after swinging away the removable bearing which is mounted between parallel levers 12 pivoted at 13 and coupled to the clutch 9 through a cam 74, lever 63, push-rod 67 and lever 68 so that the drive to the mandrel is interrupted when the bearing is removed. Normally, the bearing is seated within a fixed ring 15. Rollers 16 on the mandrel co-operate with rollers 17 mounted on a plate 20 supported by rods 22 and adapted periodically to be fed up to the mandrel against the action of springs 25 by means of a cam 19 acting on a follower 26. The position of the follower relative to the rollers 17 may be adjusted by a milled nut 29 to vary the depth of the corrugations produced. When one series of corrugations has been formed, the cam 19 permits the springs 25 to withdraw the rollers 17 and during this period the tube is fed forwards by means of lifting fingers 30 mounted at the end of a lever 31 movable in a vertical plane about a pivot 32 by a cam 44 and in a horizontal plane about a pillar 33 by a cam 42. The cams 19, 42, and 44 are mounted on a common shaft 43 geared to a shaft 58 carrying a sprocket 55 driven by a chain from a sprocket 49 adapted to be coupled to a sprocket 46 by the clutch 9, a chain drive from a common source of power passing around the sprockets 46 of all three sets of mechanism. When the work has been corrugated on the lower mandrel, it may be removed and the corrugations made deeper on the mandrels of the second and third sets of mechanism.
