IPC: F02M69/00
Filed: 1926-03-09
Abstract: 271,966. Enock, A. G. March 9, 1926. Spray carburettors.-In an internal-combustion engine for a motor car, compressed air is admitted to the air inlet or mixing-chamber of the carburettor through a valve-controlled pipe connected to a receiver to which air is supplied from a compressor driven indirectly from the engine, means being provided for disengaging the driving- mechanism and operating the compressor by hand or other auxiliary means. The compressor, which may be of the rotary, or reciprocating type, is driven from the engine or from the road wheels of the car through a belt, chain, or the like and a suitable clutch, and the auxiliary means may comprise an electric motor driven from the car battery. The air may enter the carburettor through a conduit passing through or around the fuel nozzle, or through a nozzle situated in the air intake and comprising either a single outlet orifice, or a. ring provided with a series of orifices which may be controlled by a hand-operated valve member passing through or around the ring and having a flange projecting over the orifices. As shown in Fig. 8, air is supplied, through a pipe B controlled by valves B<1>, B<2>, both to a ring provided with orifices b opening into the air intake a and to a conduit b<1> surrounding the fuel nozzle a<1>. The ring may be adjustable on the pipe B and coact with a fixed plate in the intake a to vary the air supply from the orifices b. The air supply pipe or the receiver may be heated by exhaust gases, the cooling water, or an extraneous source of heat.

In Fig. 1 the control lever 1 actuates the reversing lever 3 with a certain amount of lost motion between abutments 4, 5, and a cam 6 actuates lever 7, switch 9 and electric valve 10 to interrupt the feed to the turbine before the reversing gear is engaged. Fig. 2 shows an arrangement of interlocking notched cams 13, 14 on the levers 11 and 12 controlling the feed to the turbine and the reversing gear which has the same effect. With the arrangement shown in Fig. 1, the electric valve 10 may be used to admit compressed air to a cylinder which moves a spring-loaded piston to open a valve in the pipe supplying gas to the turbine; alternatively, as shown in figure 4, such spring-loaded piston 37 may rock the lever 34 to position 40, whereby rod 32 is moved to the right to stop the injection pump 31 of the gas generator which supplies the turbine. The pump is normally controlled by control rod 35. Stop 41 limits the closing stroke of the pump but when the pump is being manually controlled by rod 35, abutment 42 is removed from the path of stop 41 on excessive movement of the control rod by means of collar 46 which moves levers 45 and 43; with this arrangement the manual control is operative over the full range but when the pump is closed automatically it is not fully closed, which keeps the turbine running slowly to facilitate engagement of the reversing gear.

Abstract: 802,146. Graining lithographic plates. CARTER, Ltd., J. W. & T. H. and RAINES & PORTER, Ltd. March 8,1955 [March 9, 1954], No. 6889/54. Class 60. A machine for graining lithographic plates has a gyratory trough 10 provided at one end, with a displaceable gate and a shoot 11 down which the marbles fall on being discharged from the trough 10. A bucket 12 is attached by brackets 15, at longitudinally spaced points on its well 14, to a pair of cranked bucket raising and lowering levers 16 connected to and movable by a shaft 17 supported by bearings 18 secured to a stand 19. The inclination of the bucket relative to the levers is adjustable. The mouth 13 of the bucket for receiving marbles discharged from the trough is capable of enlargement laterally, the upper length of the wall 14 which forms one lip of the mouth being a displaceable lip 21 pivoted at 22 to the end plates 23 of the bucket by cheek plates 24. Attached at 26 to the cheek plates 24 are links 27 connected at 30 to members 31 pivotally mounted at 32 on the bucket; the pivots and the members 31 carry rollers 33, 34. Springs 37 act on shoulders 38 on the links, so that when the bucket is in its raised position, Fig. 3, for discharging marbles from the bucket into the trough, the lip 21 is closed and the members 31 are urged clockwise about the pivots 32. When the bucket is moved to its lowered position to receive marbles from the trough, engagement of the roller 34 with the residue tank 35 moves members 31 counterclockwise about the pivots 32 so that links 27 open the lip 21 against the action of the springs 37. In a modification, the springs 37 are omitted and the members 31 carry a weight to effect their movement about the pivots. Each link 27 comprises a part 29 telescoping into a part 28, the parts having a pin and slot connection 39 and being urged apart by a spring 40. A spillage 41 is pivoted at its rear end on the shaft 17 and its forward end is supported by a fixed pillar 42 supported from the stand 19 by a projecting shelf 43.

Title: Improvements in or relating to the directional determination of a source of sound waves
IPC: G01S1/72
Filed: 1930-03-03
Abstract: 348,262. Locating source of sound waves. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Submarine Signal Co. ; 160, State Street, Boston, U.S.A.) March 3, 1930, No. 7000. [Class 118 (ii).]. A method of determining the direction of a source of sound waves consists in receiving the waves whose direction is to be determined, introducing relative time retardation means into the paths of the received waves to bring said waves into phase and simultaneously aurally and visually observing when said waves are in phase. In the form shown in Fig. 1, six sound receivers 1 .. 6 are arranged so that receivers 1 .. 4 form the " left base and are connected to one path 7 of the compensater, the receivers 2 .. 6 forming the " right base being connected to the other path 8 of the compensater. The output terminals of the retardation lever 7, 8 are connected to the primaries of transformers 9, 10 respectively. The secondaries of the transformers 9, 10 are connected in series in opposition by a conductor 12. The other terminals of the secondaries are connected by lines 13, 14 to a two-stage amplifier containing tubes 15, 16. The output of the tube 16 is led to the grid of a detector tube 18 of which the plate current is indicated by a visual indicator such as a galvanometer 19 when the switch 23 is closed. The plate current is adjusted by varying the plate potential supplied by the battery 24 and the steady current in the plate circuit when no signal is being received is annulled by shunting the galvanometer with a battery 21 and resistance 20. The telephone 11 is connected across the lines 7, 8 and the sound is at maximum when the compensator is properly adjusted while the galvanometer shows a minimum indication. In a modification, Fig. 2, six receivers 25 .. 30 are connected in two groups of three each to retardation lines 31, 32 the output terminals being connected to the primaries of transformers 35, 36. The secondaries of these transformers are connected in series in opposition to an amplifier and visual indicator 37. The telephone receivers 33 are connected to produce a binaural effect with the switch 34 open. When the switch 34 is closed, the telephones indicate a maximum. With either form, the visual indicator would indicate a minimum when the compensater is focused. By reversing the connections to the secondary of transformers 10 or 36 the galvanometers may be made to indicate a maximum. Alternatively in Fig. 1, the amplifier and indicator may be interchanged with the telephones when the latter indicates a minimum and the galvanometer a maximum.
