IPC: F02M17/14
Filed: 1916-11-14
Abstract: 110,953. Speed, J. A. Nov. 14, 1916. Spray carburettors. -An automatic valve admitting air to the mixing-chamber of a carburettor is combined with means for variably restricting the flow of liquid fuel, and with a dash-pot for retarding the opening of the air valve while permitting free closing thereof. An elevator s carrying the fuel-delivery jets t<1> is moved vertically by the suction in the induction pipe, and controls air inlet ports v<1>, v<11> and a fluid-supply valve o. In consequence of the varying elevation of the jets t<1>, the air and fuel supplies are not proportional, and the desired changes in the mixture under different conditions are obtained. A dash-pot consisting of a piston n with a one-way plate valve n<11> controls the movement of the elevator s, retarding the opening of the air valve v<11>. Fuel from the float chamber a passes down a passage k and fills the cylinder m, m<1> containing the piston n. Inclined vanes w carried by the elevator above the jets t<1> impart a rotary movement to the mixture in the carburetting-chamber. An inclined vent tube vv cauaes the part s to rotate slightly, throttling the air inlet ports v, v<1> at high speeds. A passage y places the space below the air valve in communication with the atmosphere and relieves back-firing pressure. A fuel supply passage d to the float chamber may be adjusted bv rotating a part b around an inclined bolt c. Air inlet openings v are rotated to any desired position and clamped by a collar a<1>. In a modification, the rate of fuel supply for different positions of the air valve depends upon the cross-section of the fuel valve o, which has a shape other than conical,

Title: Improvements relating to vehicle suspension systems
Inventor: MOULTON ALEXANDER ERIC
IPC: F16F9/34
Filed: 1958-05-23
Abstract: 870,489. Road vehicle spring suspensions; springs. MOULTON DEVELOPMENTS Ltd. May 23, 1958, No. 16612/58. Classes 108(2) and 108(3). In a suspension system of the conjugate hydraulic type described in Specification 813,259, each hydraulic displacer unit 2, 2A, is associated with two-way rubber flap valves 8, 8A. The front suspension unit 2 (Fig. 5) acts between a suspension link 3 and an abutment 13 on the vehicle frame 1. The unit 2 is connected by a hose unit 7 to the rear suspension unit 2A which acts between an arm (not shown) rigid with the boss 15 of a wheel suspension link 5. Each unit 2, 2A comprises a diaphragm 10 (Fig. 12) having an inner liner of butyl rubber 26 and a bead 28 hermetically clamped between the flange 27 of a head 9 and the wall of a skirt 29. A central portion 30 of the diaphragm 10 is located in the cavity 31 of a piston 32 which has a tapered skirt 33. The piston 32 is rigid with a strut 11 which has a ball joint connection 34 with the respective wheel suspension link. A partition 38 rigid with the inside face of the head 9 is formed with ports 43 which are overlapped by the arms 8B of the rubber flap valve 8 an identical valve 8A disposed at right angles to the valve 8 overlies a further pair of ports (not shown) in the partition 38. The valves 8A, 8B, are in prestressed engagement with their respective ports. The hose unit 7 comprises a thick-walled rubber extrusion 19 formed with external ribs 20 (Fig 7). The rubber tube 19 is encased in a relatively rigid sleeve 23 which may be of woven steel braid, steel tube, textile braiding, spirally wound tubing reinforced with fabric or paper, or interlocked spiral metallic coils. When the sleeve 23 is of steel braid a protective covering of polythene tubing may be provided. When during operation, liquid in the system is put under compression, the tube 19 is distended and the gaps between the ribs 20 tend to be filled. The linkages of the front suspension have a smaller mechanical advantage than those of the rear suspension. As the rear road wheel moves from the rebound to the bump condition there is a decrease in mechanical advantage of the linkage connecting the road wheel to the unit 2A. Rear suspension linkages of the kind described in Specification 27450/56 in which the centre of gravity of the spring mass is slightly raised as the vehicle pitches, may be incorporated in the present invention.

Abstract: 190,503. Angus, A. R. June 20, 1921. Track apparatus actuating signals on trains and for stopping trains.- Electromagnets restraining signals or train stopping apparatus on a train from operation are energized only by the proper oscillation of an oscillatory means and not by the continued location of the said means in any position. Two oscillating relays 7, 16, each responsive only to one frequency are connected through a switch 4, set according to the direction of running of the train, to a means for supplying energy from the track rails or from auxiliary conductors. The armature cf one relay is thereby oscillated under ' line clear ' conditions and current is intermittently supplied from the battery 25 through the transformers 75, 81 and the relays 30, 40, the armatures of which, in series, control the relay 54, and thereby, the stopmagnet 63. In a modification the relays 30, 40 are supplied directly without transformers and all the relays are made to release their armatures slowly by the use of shunting resistances. In a further modification, only one oscillatory relay is used and is connected in one or other of two tuned circuits to respond only to the proper frequency the apparatus then agreeing with that described in Specification 190,426.

Title: Improvements in or relating to electric control systems for fluid fuel burning apparatus
IPC: F23N5/20
Filed: 1949-06-20
Abstract: 660,872. Electric control system for fluid fuel burners. ROBERTSHAW-FULTON CONTROLS CO. June 20,1949, No. 16931/49. Class 75(i) The supply of fluid fuel to a burner is controlled by a thermionic valve, the grid voltage of which is obtained from the detector arm of a bridge circuit, one arm of which is a temperature responsive resistance exposed to a pilot burner or affected by a main burner. As shown in Fig. 1, the apparatus comprises a triode valve 52 with the grid/cathode 54/58 connected as the detector arm of a bridge A, B, C, D, whose brances are formed by resistances 78, 80, 83 and 85. The apparatus operates in the following manner, a main fuel valve 14 on being opened passes fuel to a pilot burner 18 and closes a switch 16 to energize a cathode heater 56 and a pilot burner igniter 22. The pilot burner 18 heats the resistance 78 of the bridge, thereby to reduce the grid bias to render the thermionic valve 52 conductive, whereupon a relay 30 is energized to close its contact 34, thus energizing and opening an electro magnetic fuel valve 24 to admit fuel td the main burner 10 and at the same time energizing a relay 40 to open a contact 48 to cut off the current to the pilotburner igniter 22; the relay 40 is now held up by a circuit over its own front contact 50. Should the pilot 18 be extinguished, the resistance 78 cools, thus rendering the thermionic valve 52 non-conductive, thereby to de-energize the relay 30 and so to open contact 34, thus releasing and closing the electromagnetic fuel valve 24 but leaving the relay 40 locked up. Thus the system is not recycling and requires manual re-operation of the main fuel valve 14 and switch 16. A recycling system shown in Fig. 2, has a bimetallic switch 128 in place of the relay 40 shown in Fig. 1. The system operates in a similar manner to that previously described until relay 30 closes contact 34, thereupon the bimetallic strip 130 is heated by a coil 132 and opens a contact 134 to cut off the current supply to the igniter 22. Should the pilot 18 become extinguished the resistance 78 cools off and the relay 30 opens its contact 34 so that the strip 130 cools off and in due course closes the contact 134 to restore the circuit to the igniter 22 and the sequence of operations described is repeated. Other arrangements using a tetrode thyraton valve and the electromagnetic valve 24 as the relay 30 are described.

Abstract: 1308031 Ignition safety device JUNKERS & CO GmbH 10 April 1970 [11 April 1969] 17039/70 Headings F4F and F4T An ignition safety device for a gas fired appliance having a solenoid safety valve 11 and a main valve 13 for controlling the flow of gas to a burner of the appliance, and a piezoelectric igniter device 14, the safety device comprising a contact breaker 15 which prevents sparking of the igniter device when the valves are not in their "ignition position" where the main valve 13 is closed and the safety valve 11 is open, thus supplying a limited amount of gas to the burner, this being effected by means of a bell crank lever 151 which is pivotably mounted at 155 and which has a contact surface on one arm cooperating with a counter contact surface 152 connected to the igniter device by a high tension cable 144, the other arm of the lever being displaceable against the action of a torsion spring (156, Fig. 3, not shown) on the pivot pin of the lever in a downward direction by depression of the operating handle 116, thus opening the contacts and placing the valves in the "ignition position". Actuation of the igniter device now produces sparks to ignite the gas issuing from the burner, and on returning the operating handle to its normal position as illustrated, the main valve 13 is opened and the lever is returned by the torsion spring to the position shown where it short circuits the ignition device through the torsion spring (156, Fig. 3, not shown) which is electrically connected to the housing of the safety device and acts on earth. The lengths of the arms of the lever are in the ratio of the travel of the operating handle and the required maximum separation of the contacts. Also illustrated is a thermostatic valve 12 which may be adjusted by means of a gear-wheel 121 mounted on the operating handle 16 which meshes with a toothed member 122. Rotation of the handle 116 thus rotates the member 122 which in turn acts upon the bellows 124 of the valve 12 by way of a spindle 123.
