Title: Improvements in throttle control devices for aircraft engines
IPC: F02D9/00
Filed: 1943-04-08
Abstract: 567,106. Fluid-pressure servomotorcontrol systems. HOBSON (AIRCRAFT & MOTOR) COMPONENTS, Ltd., H. M., and GREENLAND, L. S. April 8, 1943, No. 5616. [Class 135] A throttle control for an aircraft engine is arranged so that movement of the pilot's lever from the slow running to the cruising boost position is effective to produce, through the agency of an interposed mechanical linkage, a relatively small movement of the throttle valve (e.g. 10 degrees), the major portion of the required movement of the throttle valve being communicated by the servo-piston of the boost control device. As shown in the Figure, which shows the parts in the slow running position, the pilot's lever is fixed to a shaft 31 mounted in bearings and carrying an eccentric 32 arid a cam 33. A yoke 34 surrounding the eccentric is connected by a link 35 with the throttle valve 61 and by a link 36 with the servopiston 38 loaded by a spring 55. The cam 33, which is the variable datum cam, has a cam slot 39 engaging a roller 59 on a link 40. The link is slotted at its upper end to engage the shaft 31 and at its lower end is coupled by a lever 41 and link 42 with a floating lever 43. An intermediate point of this lever supports the capsule stack 45 exposed to boost pressure and is connected to a valve 46 forming part of a variable area fuel metering orifice through which fuel is pumped to the engine as described in Specification 566,323, [Group XXVII]. The other end of the lever 43 is coupled to a second piston 47 loaded by springs 48, 49. The two servo-pistons are controlled by a single valve actuated by the capsule stack subject to boost pressure. According to the Provisional Specification, the power piston may be connected to the throttle valve through a floating lever pivoted on one arm of a bell-crank, the other arm of which engages a cam slot on the pilot's lever. In another form, the floating lever is . formed integrally with an eccentric strap engaging an eccentric on the pilot's lever. Specifications 419,113, [Group XXVII], 483,049 and 529,704 also are referred to.

Title: Electric shutter for a camera
IPC: G03B7/083
Filed: 1974-05-13
Abstract: 1475183 Camera shutter control ASAHI KOGAKU KOGYO KK 13 May 1974 [12 Feb 1974] 06385/74 Heading G2A A camera shutter control circuit has first and second circuits connected in parallel with each other to control a shutter closing electromagnet 27, one de-energization of circuit 20, 21 including a mechanically operated switch 21 for providing very short exposures, e.g. <SP>1</SP>/2000 second, and the other including a switching circuit 24 controlled by a timing circuit. Preferably the mechanical switch 21 also serves as a timing switch for the timing circuit, the first circuit and the timing circuit each including a forward biased diode 20, 19 for isolation purposes. As shown. (1) if a switch 28 is opened the timing circuit id disabled. When a shutter release 29 is pressed the shutter opening curtain is released and the electromagnet 27 is energized to hold the closing curtain. Movement of release 29 allows a cam 30 to rotate followed by levers 31, 33 until a pin 36 stops lever 33. This separates the levers and thus opens contacts A, B forming switch 21. Opening switch 21 de-energizes the electromagnet to release the closing curtain. A screw 34 determines when levers 31, 33 will separate. (2) if switch 28 is closed the timing circuit is operable. It comprises a photo-electric element 5, logarithmic diode 7, diaphragm resistors 10, 11, film speed resistor 12, manual shutter time resistor 13 memory capacitor 15 and timing capacitor 17. Release takes place as in (a) up to where levers 31, 33 open contacts A, B of switch 21. The electromagnet is kept energized by switching circuit 24 in this case, and opening of switch 21 initiates discharging of the timing capacitor 17 until switching circuit 24 is triggered to de-energize the electromagnet and allow the shutter to close.

Title: Improvements in or relating to electric synchronising apparatus
IPC: H02J3/42
Filed: 1935-03-05
Abstract: 453,146. Automatic control systems. REYROLLE & CO., Ltd., A., Hebburnon-Tyne, and LEYBURN, H., 212, Wingrove Road, Newcastle-on-Tyne. March 5, 1935, No. 6951. [Class 38 (iv)] Speed.-An arrangement for maintaining two A.C. systems closely in synchronism comprises one or more differential relays responsive to phase displacement between the systems, whether lagging or leading, which effect control of one or both systems to bring them into phase. The system also includes an arrangement responsive to frequency difference with means for connecting it in circuit in dependence on the circuit conditions. Coarse adjustment is effected by the arrangement responsive to frequency difference comprising a synchronizing relay F and an auxiliary synchronizing relay G. The relays are so connected to the systems that the relay F lifts and the relay G opens as the system voltages approach and pass the synchronism point, the periods of closing and opening being so adjusted that when the frequency of system A is lower than that of system B the synchronizing relay F remains de-energized but is energized when the frequency is higher. If the frequency is lower, the relay G periodically completes a circuit from the D.C. supply M through the contacts G<2>, F<2> to the raise motor relay N. The period of energization is determined either by the energization of the relay G or by the opening of a time delay relay K. If the frequency is higher the relay F completes periodically the circuit of the lower relay O. When the frequency difference is slight the relays F and G complete the circuit of a time delay relay L sufficiently long for it to close so that when relay G opens, the circuit of the operating coil P is completed causing change over from the frequency responsive control to phase responsive control. This comprises two differential relays T and S, one closing in response to phase lay and the other in response to phase lead. These control induction disc motors V, U which, when energized, impulse the raise or lower relays N, O. These induction disc motors have weighted rotors so that they stop with the contacts V<2>, U<2> open. Change back to frequency control takes place when the phase difference becomes such that relay G is energized to close the circuit of coil Q<1> thereby tripping the switch P. This switch has a contact P<4> which, in the position for frequency responsive control, short circuits a resistance R2 in the motor field circuit so that a more rapid adjustment is effected. If desired a single differential relay of the centre zero double contact type may be used, to give more accurate control a number of relays may be used each responding at a different value. Alternatively, in conjunction with the relays S, T, a number of relays of the plain lift and fall type connected between corresponding phases of the main and controlled systems and acting to vary the amount of resistance in the field circuit of the governor motor may be used. Specifications 294,970 and 294,971, [both in Class 38 (iv)], are referred to.
