Patent GB-626291-A (GB)
Title: Improvements in and relating to remote control systems
IPC: G05D3/12
Filed: 1944-07-29
Abstract: 626,291. Electric follow - up systems. SPERRY GYROSCOPE CO., Inc. July 29, 1944, No. 14539. Convention date, July 30, 1943. [Class 40 (i)] In a remote control system, a signal, varying in sense and magnitude in conformity with a controlling member, controls an electric motor in corresponding speed and direction and this determines the rate of a variable speed driving device connected with the load. A controlling shaft 17 positions a rotor winding 18, fed with alternating current from a source 22, and currents induced in the stator 21 are passed to a remote stator 23. Error signals generated in the controlled rotor 25 are passed to phasedetecting valves 34, 35 which produce voltages across resistors 47, 51 dependent on the polarity and magnitude of the error signals, and these voltages are amplified in valves 65, 66 whose outputs are connected to the field winding 69 of a differential motor 71. The armature 85 is fed from a source of D.C. supply 86 and thus rotates shafts 88, 14 as long as an error signal exists, thereby shifting the movable element 97 of a variable ratio friction driven device 92, driven by a constant speed motor 99. The driven member 102 drives the controlled shaft 28, carrying the rotor 25, and output shaft 13. As long as there is a discrepancy between the speeds of the shafts 17, 28 an error signal exists which adjusts the variable speed device until there is no signal and no phase lag between the shafts. In order to prevent hunting by the variable speed device, a differential gearing 104 is adjusted, through gears 109, by the rate shaft 14 so as to produce an additional displacement directly proportional to the movement of the armature 85. The amplifier valves 65, 66 are stabilized by degenerative feed-back obtained from a magneto generator 114 driven by the motor shaft 88.

Title: Suction control apparatus for chamber ovens or retorts
IPC: C10B27/06
Filed: 1931-05-18
Abstract: 365,934. Fluid-actuated valves; liquid-seal apparatus. STILL, C., Rec klinghausen, Westphalia, Germany. May 18, 1931, No. 14641. Convention date, May 19, 1930. [Class 135.] In coke ovens or retorts having a gas collecting space above the charge, and ducts in the charge from which distillates are withdrawn, means are provided for connecting the ducts with a gas collecting pipe, and controlling the flow of gas from the ducts by a resistance the amount of which is dependent upon the gas pressure in the space over the charge. Ducts 5 in the charge lead through tubes 6, 9, 10 to a junction 12 at the top of a pressure regulator 14 connected by pipe 16 with an hydraulic main 17 in which is maintained a vacuum of about 250 mm. of water. In the gas collecting space 4 atmospheric pressure is maintained. The upper part of the pressure regulator 14 contains water 22 constantly supplied through a pipe 27, and depending tubes 24 connecting with the gas inlet 12 are immersed in the water the level of which is varied by an outlet valve 32 the movement of which is dependent upon the pressure in the space 4. A float 30 on a spindle 31 carrying the valve 32 has its underside connected with the atmosphere by a pipe 48, and is supported by liquid 29, the level of which is maintained by an overflow vessel 38 adjustable on a hollow stem 40, discharge pipes 43, 44 being provided. A valve 37 serves for emptying the vessels 35, 38 and a pipe 18 communicates with the space 4 over the charge. If a vacuum of 250 mm. of water is maintained in the outlet main 17, and a suction of 110 mm. is desired, in the ducts 5, the depth to which the pipes 24 are sealed in the regulator 14 should be 140 mm., the water being discharged through the valve 32 at a rate corresponding with the inflow through pipe 27, and depending upon the position of the float 30. If the pressure in the space 4 rises, the liquid 29 falls, the valve 32 opens, and the liquid level in the regulator is lowered so that the effective suction in the ducts 5 is increased, and the normal atmospheric pressure is restored in the space 4. The gas may be withdrawn partly from the space 4 into a separate hydraulic main.
