Patent GB-106632-A (GB)
IPC: F02D1/00
Abstract: 106,632. Fenchelle, H. E. March 24, 1916. Regulating.-Between the fuel-injection valve lever B and its cam C is a distance-piece D which can be adjusted to vary the quantity of fuel admitted without altering the period in the cycle when admission begins. The piece D swings about the cam shaft on an arm E and is adjusted by an eccentric F; it has flat faces d<1>, d<2> for forward and backward running respectively, with a recess d<3> between them. It imparts the greatest lift to the valve when in the extreme positions, and to reduce the lift it is moved in an opposite direction to that in which the cam rotates.

Title: Improvements in and relating to electrical control systems for sequence and timing control
IPC: G05B19/06
Filed: 1955-04-14
Abstract: 783,359. Control systems for resistance welding. GENERAL ELECTRIC CO. April 14, 1955 [April 14, 1954], No. 10799/55. Class 38 (4). The " squeeze," " weld," "hold " and " off " periods necessary in resistance welding are controlled by condensers 28, 29 and timing resistors 32, 33, 30, 31 which are sequentially brought into operation by interlocked electromagnetic switches 1, 14 which also control the firing circuit of the welding ignitrons and the energizing circuit of the solenoid valve controlling the welding jaws. Upon operation of an initiating switch 13 a valve 2 conducts, causing operation of switch 1 which holds in over contacts 5. Contacts 3 complete the energizing circuit for the solenoid valve so that the welding jaws now " squeeze the work, and contacts 8 open to prevent firing of the ignitrons. Contacts 9, 10 disconnect condensers 27, 28 from a charging rectifier 25, whilst condenser 29 is connected, over contacts 7 for charging by rectifier 39. Contacts 6 connect timing condener 28 to the grid of the valve and contacts 4 cause condenser 27 to discharge into the winding of switch 14, which operates and then holds-in by steady current supplied over resistor 26 and rectifier 25. " Squeeze " timing resistor 32 is thus connected, over contacts 18, in a discharge circuit for condenser 28. Contacts 16 prepare the firing circuit for the ignitrons and contacts 15 provide another circuit for maintaining the solenoid valve energized. When condenser 28 is discharged vaive 2 ceases to conduct and switch 1 drops out, thereby completing the firing circuit and initiating flow of welding current, whilst simultaneously disconnecting condenser 29 from charge and reconnecting condenser 28 for charging. Condenser 27 recharges, with reversed polarity, over contacts 10, 20 and rectifier 39. Condenser 29 now discharges through the " weld " timing resistor 33 and then recharges with opposite polarity over rectifier 25, the reversed potential being applied over contacts 18 to the grid of valve 2 which eventually re-fires and again operates switch 1. The firing circuit is thus opened, condenser 27 discharges through switch 14 which drops out, and condenser 28 starts to discharge (over contacts 22) through resistor 30 to time the " holding " period, contacts 3 'maintaining the solenoid valve energized. Condenser 28 eventually tunes out and valve 2 ceases to conduct, causing switch 1 to drop out and open its contacts 3 to terminate the " hold " period. Condensers 27, 28 recharge over rectifier 25 and condenser 29 commences to discharge through the " off " timing resistor 31, the hold-off bias which the condenser applies to valve 2 (over contacts 22 and resistor 30) eventually falling to a value which allows the valve to re-conduct and start a new cycle of operations, provided switch 13 is maintained closed and switch 34 is in the position shown. In the other position of switch 34 condenser 29 is maintained on charge so that the valve cannot reconduct to initiate another cycle.

Title: Improvements in and relating to multi-rotor helicopters
IPC: B64C1/00
Filed: 1948-04-22
Abstract: 646,865. Multi-rotor helicopters. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. April 22, 1948, No. 11087. [Class 4] In a multi-rotor helicopter having three or more lifting rotors, control in roll is effected by transverse differential collective pitch control, and control in yaw by differential inclination in the rolling plane of the lift vectors of the rotors situated forward and aft of the centre of gravity. Fig. 4 shows a control system for a machine with three rotors, as described in Specification 591,982, in which a spider with three arms 47, 48, 49 is mounted for universal tilting and vertical movement by operation of an attitude control lever 38 and a collective pitch control lever 40, respectively, the ends of the spider arms being connected by links 50, 51, 52 to the collective pitch control systems of the respective rotors. Transverse movement of the lever 38 is transmitted to the spider by links 62, 63, 65, 56 to move the links 51, 52 equally in opposite directions, resulting in differential variation of the collective pitches of the sideby-side rotors. Fore-and-aft movement of the lever tilts the spider about a transverse axis, through links 61, 53, 55. The rudder pedals 39 are connected by links 86, 87, 82 to a pivoted T-bar 75, which is connected by links 77, 78, 79 to the cyclic pitch control systems of the lifting rotors, the arrangement being such that operation of the pedals results in the lift vectors of each of the side-by-side rear rotors being inclined in the transverse plane oppositely to, and through half the angle through which the front rotor lift vector is tilted. Fig. 7 shows a modified control system for a helicopter with four rotors arranged in diamond plan formation, the collective pitch mechanisms of the rotors being controlled by a spider with four arms 147, 148, 149, 153, and the T-bar 75 being replaced by a lever 75a with links 77, 155 at its ends which operate the cyclic pitch controls, to effect equal and opposite transverse inclinations of the lift vectors of the front and rear rotors only upon actuation of the rudder pedals, the side-by-side rotors not having provision for transverse cyclic pitch control. Preferably all the rotors are driven in the same direction. Provision may be made for cyclic pitch control in all phases, as described in Specification 615,156, and the fore-and-aft cyclic control mechanism may be interconnected with the other controls in the manner described in Specification 616,227. If desired, the threearmed spider shown in Fig. 4 may be replaced by a T-bar which, like the T-bar 75 may be constructed and power-operated as described in Specification 646,864. Specifications 644,524 and 646,866 also are referred to.
