Title: Improvements in carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1936-02-10
Abstract: 474,975. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH. Feb. 10, 1936, No. 4029. Convention date, Feb. 8, 1935. Addition to 471,508. [Class 7 (iii)] In a carburetter having a fuel outlet opening into the induction passage on the engine side of the throttle valve controlling the passage, and wherein the fuel output controlled from the suction in that passage behind the throttle valve is further subjected to superimposed control from a manometric control member operated by a movable wall separating two chambers, one of which is connected with the induction passage behind the throttle valve, preferably in the vicinity of the fuel outlet, while the pressure in the other chamber is unaffected by the pressure in the induction passage or in the atmosphere, as set forth in the parent Specification, a supplemental adjusting member is adapted to alter the effect of the manometric control member on the discharge of fuel. The pressure at which fuel is supplied to a nozzle 7, Fig. 1, from a chamber 10 of a diaphragm type regulator 9 is varied by a valve 23 in the dry chamber 15, which is open to the atmosphere or air inlet through a calibrated orifice 16 and passage 17, the valve being operated by a bellows 22 in a chamber 18 communicating with the mixing chamber 1 above the throttle valve 4 which controls a valve 25 in the nozzle 7. The action of the valve 23 is modified manually to vary the composition of the combustible mixture by rotating a cam 130, which engages a plate 126 on a rod secured to the base 122 of the bellows 22. Alternatively, the bellows may operate through a lever, the fulcrum of which is adjusted by movement of the cam. In other forms, the additional control comprises a valve which opens or closes a restricted byepass disposed either between the chambers 18, 15 or between the chamber 15 and the passage 17, this latter providing an altimetric control, or the two byepasses may be used together, their valves being coupled together so that one opens as the other closes. A float chamber may replace the diaphragm regulator 9. To provide emulsifiedfuel to the mixing chamber 1, the dry side 45, Fig. 9, of the diaphragm 12 is kept at the pressure of the air inlet, the fuel needle valve 48 controls an inlet 43 into an intermediate chamber 50, the pressure in which is determined by the size of an air inlet 52 controlled by a valve 54 connected to the bellows 55, the emulsified fuel entering the mixing chamber through a calibrated passage 51 around the stem of the needle valve 48 and through a byepass 154 which may be closed manually to weaken the mixture. The weakening may be accomplished by replacing the byepass 154 by one connecting the intermediate chamber 50 to the air inlet, this being opened to weaken the mixture, or the two byepasses may be used conjointly. Either byepass may be used with the construction shown in Fig. 4 of the parent Specification, or the cam 130, Fig. 1, with the constructions of Figs. 5, 6, and 7 thereof.

Title: An improved method and means for humidifying the atmosphere in ovens
IPC: A21B1/08
Filed: 1934-05-11
Abstract: 438,027. Diffusing steam in ovens. WARNER, A., 7, Fernlea Road, Balham, and HOSKINS, N., 18, Bolingbroke Grove, Wandsworth Common, both in London. May 11, 1934, No. 4313. [Class 28 (i)] The atmosphere in bread-baking ovens is humidified by atomizing water and projecting it into the oven space by the action of air compressed to a degree greater than that obtainable with a blower or fan, whereby a water mist is created which converts readily to water vapour or steam at a temperature corresponding to that prevailing in the oven. As shown, the atomizer is mounted in a housing in the wall of the oven, and comprises a body portion, ending in a nozzle h, slidable in a tube k. A cap o is detachably secured to the outer end of the tube k and, when in position, prevents the total withdrawal of the body portion which carries a stop n. When the body portion is pushed forward, into the oven, a projection m engages, and opens, a pivoted flap closure l for the end of the tube k. When the cap o is disconnected, the body portion may be completely withdrawn from the tube. Air is admitted through the pipe a and water through the pipe b. The water and air supply plant may comprise a wheeled truck on which is mounted an air compressor, driven by an engine or motor, and a water tank having a valve controlled filling-hopper, a gauge glass and a drain valve. The compressed air is admitted to the top of the water and is withdrawn from the tank through a valve in the top cover. The water is forced, by the air pressure, up through a pipe which descends to the bottom of the water space, and through a valve to pipes leading to the atomizer. The connections to the atomizer include flexible pipes r, and regulation is effected by valves p, q.

Title: Improvements in torque limiting means for torque transmitting mechanism
IPC: F16D43/202
Filed: 1944-03-08
Abstract: 575,522. Overload release clutches. SINCLAIR, H. March 8, 1944, No. 4331. [Class 80 (ii)] [Also in Group XXIX] An overload release clutch adapted to maintain full engagement between the clutch members up to a critical value of the torque transmitted and then to give substantially instantaneous release, comprises dogs 54 on a flange 55 of a driven shaft 51 which engage dogs 58 on a helical toothed gear 53 mounted for rotation upon shaft 51 and engaging a gear 52 fixed on a driving shaft 50. Owing to the helical teeth on the gears 62, 53, the transmission of torque tends to move gear 53 to the left to disengage the dogs 58, 54 and gear 52, together with its shaft 50, to the right against a piston member 77. The axial movement of gear 53 is prevented, however, until an abutment ring 59, which is provided with teeth 60 co-operating with teeth 62 on a fixed ring member 63, is rotated to bring the teeth 60 and 62 out of line. The rotation of the ring 59 is effected by a spring 64, Fig. 7, but a catch lever 68 engaging a tooth 71 normally restrains such operation. The piston member 77 is subjected to fluid pressure from a'conduit 79, controlled by a restriction 81 and an exhaust port 82, which opposes movement of the gear 52 due to normal torque, but on the torque reaching a predetermined critical value, the gear moves the piston to the right to close the exhaust port 82 by a valve 83 with a resulting build-up of pressure in the piston chamber. This pressure is transmitted through conduit 90 to a bellows 91, Fig. 8, which operates the and 95 of catch lever 68 which results in the catch releasing the ring 59 which is rotated by spring 64 to allow axial movement of the gear 53 to disengage the dogs 58, 54. To reset the clutch, either the driving shaft 50 must be rocked backwards through a small angle, or the driven shaft 51 moved forward, which allows reverse-facing ratchet pawls 96 on the flange 55 to engage the teeth 58 of gear 53 and to slide the gear to the right to re-engage the dogs 58, 54. At the same time a resetting lever 99 must be actuated to engage a tooth 100 on, and move ring 59 back, to engage with the catch-lever 68 again, the gear 52 and piston 77 having been returned to their normal positions by the pressure of the fluid behind the piston. In another arrangement, the clutch is made double-acting to operate in either direction of rotation and the tripping operation is carried out electrically from a reversible driving motor. At the critical value of current corresponding to the critical torque, a relay is energized to operate, through a solenoid, the abutment ring which allows axial movement of one of the clutch members under the torque to disengage

Filed: 1974-01-30
Abstract: 1412562 Automatic current control BURROUGHS CORP 30 Jan 1974 [29 March 1973] 04365/74 Heading G3R A transistor switch connected between a power source and a motor is controlled by the output of a bi-stable comparator circuit responsive to sensed motor current so as to maintain the average current constant. A by-pass circuit allows current to flow in the motor when the switch is open. The current feedback circuit includes a variable resistorcapacitor network for controlling the switching rate of the bi-stable circuit. As shown, a switching transistor 16 is connected between a D.C. source 4 and a motor 18 which has a series resistor so that the voltage at terminal 24 is proportional to the motor current. This voltage is fed back through a timing circuit R2, R3, 26 to an input terminal 8 of a bi-stable comparator 2 which is also connected to a reference voltage terminal 28. When the comparator output 6 is low, transistors 12, 14 render switching transistor 16 conductive, and the motor current increases until a desired level is reached, whereupon the feedback voltage is sufficient to change the state of the comparator 2 and thus turn off the transistor 16. Motor current now flows by way of a diode 22, and the comparator changes state again when the current has fallen to a second lower level after a time which is determined by the circuit R2, R3, 26. The average motor current is thus regulated.
