Patent GB-628816-A (GB)
Title: Method of and system for controlling the input to an internal combustion engine
Filed: 1946-06-12
Abstract: 628,816. Automatic control systems for engine fuel control. FAIRCHILD CAMERA & INSTRUMENT CORPORATION. June 12, 1946, No. 17614. Convention date, Nov. 8, 1944. [Class 38 (iv)] Also in Group XXXVIII]. In an internal combustion engine fuel-air ratio control system the air-mass and fuel-mass flows produce separate effects which jointly actuate the control, the fuel effect being non- reactive on the air effect. General arrangement.-In the embodiment described, the control lever 11 is set to the output of the engine, the engine throttle is automatically positioned accordngly and the A.C. signal is developed at 47, by the circuit of Fig. 1a, corresponding to the air-flow to the engine ; then in the circuit of Fig. 1b, this A.C. signal is employed to adjust the fuel supply. Adjustment of air supply.-The air-flow measuring unit 13 comprises first, the bellows 15, which are subjected to the pressure difference between the venturi throat and the intake, and which actuate the potentiometer arm 19a, and secondly the sealed bellows 22, sensitive only to the intake pressure, which positions tapping 26a. The voltage at the tapping 27a of potentiometer 27, connected in series with 26a across the A.C. source 10, is opposed to the voltage from 19a at 28, any out of balance serving to operate the motor 30 which rotates the tapping 27a to restore balance. The voltage at tapping 31a; also positioned by motor 30, represents the airmass flow. The voltage at tapping 12a, associated with the handle 11, is opposed to that of 31a, or 42a, and any out of balance, causes motor 46 to rotate the throttle shaft 46c to adjust the air-flow until the voltage at 31a and 47, equals that at 12a. The temperature sensitive resistor 20, in series with the potentiometer 19 corrects for variations of the intake air temperature. Adjustment of fuel supply.-Out of balance between the voltages at 47 and 50 causes the motor 54 to rotate and re-position 50a to restore balance. The rotor 56, of the selsyn 67 is mounted on the shaft of 54 and is therefore positioned in accordance with the voltage at 47 and mis-alignment between 56 and the receiver 66, positioned by the fuel meter 65, effects a signal in 66 to cause rotation of the motor 70, which controls the fuel valve 71 until the position of 66 corresponds with that of 56. Manual control of the fuel-air ratio is effected by the variable resistors 61, 62 and the idling mixture is controlled by the contact 64a ; in the event of engine overheating the temperature sensitive resistor 60 serves to reduce the fuel-air ratio. Upon a rapid movement of lever 11, the mixture is enriched, momentarily, by the transient signal developed in the secondary 58b, in series with the potentiometer 50.

Filed: 1944-09-25
Abstract: 604,192. Electric battery lamps. OLDHAM & SON, Ltd., and ROBERTS, A. O. Sept. 25, 1944, No. 18307. [Class 39(ii)] [Also in Groups XXXV and XXXVI] A miners' accumulator lamp which is provided with a pair of exposed charging terminals whereby the accumulator may be charged while in its casing, has one charging terminal connected permanently to one pole of the accumulator, the other charging terminal being normally dead until an enclosed magnetic switch is operated to connect it to the other pole of the accumulator, the normal inoperative position of the magnetic switch being such that it connects the said other pole of the accumulator to the bulb circuit of the lamp. A charging board for use with the lamp is provided with a pair of contacts connected to a current supply system and arranged to engage the charging terminals when the lamp is placed on the board, a magnet or electro-magnet being disposed on the board so that it operates the magnetic switch of the lamp, the circuit of the electromagnet preferably being provided with a switch which is closed by the pressure of the lamp bearing against it. Fig. 2 shows in inverted plan the relevant features of a handlamp, the accumulator 7 and bulb 1 being indicated diagrammatically. The charging terminals 8, 9 are located one on each side of a compartment 3 disposed above the accumulator housing, the terminal 8 being connected directly to one pole of the accumulator the other pole of which is connected to a terminal 10 and through a flexible lead 11 to the armature 12 of the magnetic switch. The armature is biassed by a spring 14 which normally holds the armature contact 15 against a contact 16 connected to the centre contact 19 of the bulb socket, so that the lamp circuit is completed when a press-button switch 22 is operated. Operation of the armature by an adjacent magnet breaks the lamp circuit and brings armature contact 15 against a contact 17 on a bracket connected to the charging terminal 9, thus making the circuit between the charging terminals 8, 9 through the accumulator 7. When applied to a cap lamp with a flexible lead connecting the lamp to the battery, the magnetic switch may be located in either the bulb casing or battery casing. A charging board is shown in Fig. 3, (see Groups XXXV and XXXVI).

[Class 142 (iii)] The drum-shaped cop magazine comprising discs 3, 4 fixed to a shaft 2 is locked in both directions against turning whilst the hammer contacts with the cop and during the return movement of the hammer by a pin 11<1> on the hammer 11 engaging in one of several grooves 18 formed between ribs 17 on the disc 4. Springs 5 on the disc 3 and recesses in a ring 6 screwed to the disc 4 receive the cop spindle points and heads. A torsion spring 9 secured to a forked bearing 1 is connected to a looselymounted ratchet coupling 8 engaging a ratchet coupling 7 fixed to the shaft 1, which is thereby turned until the foremost cop engages a stop 25. When the hammer descends, the coupling 8 is rotated by connections 8<1>, 10. This stresses the spring 9, which subsequently rotates the coupling 8 clockwise, whereupon the coupling 7 and shaft 1 are rotated until a fresh cop engages the stop. When the magazine is correctly positioned for cop transfer, a roller on a spring-controlled feeler lever engages in a recess formed by the laterally-tapering or rounded-out depressions at the ends of two adjacent ribs 17, a locking pin on the lever being then positioned so as not to interfere with the upward movement of a finger 14 on the transfer hammer into the path of a stop 16 on the lay. If the cop magazine is incorrectly positioned, the feeler lever is depressed by one of the ribs, the locking pin prevents the upward movement of the finger 14 and operation of the transfer hammer is prevented.
