IPC: A63F9/14
Filed: 1927-10-18
Abstract: 301,168. Cole, P. R. Oct. 18, 1927. Race games, mechanical.-A toy for use in playing a race game comprises a model race-horse, aeroplane &c. that is supported upon the forward and return leads of an endless belt, cord, wire or like member in such a manner that the model is caused to progress by the friction set up by the two leads of the belt in their passage in opposite directions against those parts of the model with which they engage. Two or more of the devices may be operated simultaneously by a corresponding number of players when playing the race game. As shown in Fig. 1, an endless cord g passes round pulleys c, e mounted on cramps a secured to opposite ends of the table. The forward and return leads of the cord pass through tubes j in a model race-horse h which is thereby supported. Upon movement of the cord by rotation of a handle d the model moves sometimes forwardly and sometimes backwardly owing to the irregularity of the friction between the tubes and the two leads. This irregularity may be increased bv knotting the cord. In a modification in which the model takes the form of an aeroplane Fig. 7, the lower tube j is replaced by a pulley p that drives a propellor l.

Abstract: 298,157. Sculier, A. Oct. 4, 1927, [Convention date]. Regulation, automatic.-Regulators for obtaining a constant alternating voltage from a variable alternating voltage comprise a condenser C, preferably electrolytic, in series with a solenoid A attracting a core B against an opposing force such as gravity or a spring or another uniformly energized electromagnet. The varying voltage is applied at terminals F, G and constant voltage is maintained at the terminals D, E by movements of the core B. A shock-absorber such as oil may be provided. The electrolytic condenser C is worked near its voltage limit and electrolysis occurs when the voltage rises. Voltage transformers, also known circuits including reactances and capacities mounted bridgewise to convert the constant voltage into a constant alternating current, may be added. The system may be used to maintain constant the potential applied to lamps in photometry and to supply the filamentheating currents in X-ray and other apparatus.

A valve 26 controls the supply to rams 14, 16 in accordance with requirements. The valve 20, in operation, provides the highest pressure required by either of valves 22, 24 as indicated by the shuttle valve 30 which compares motor port pressures. Valve 150 is the lift limit valve and valve 152 is the tilt limit valve. The valves are actuated by pressure in chambers 96 of tilt rams 14, 16. In the actuated position 162, valve 150 connects control port 62, motor port 68 and chamber 82 of ram 12 to a return conduit 110, so that valve 22 cannot supply additional pressure to chamber 82. When tilt limit valve 152 is in position 162 the control port 64 of valve 24 is connected to the return conduit 110 so that no more fluid can be supplied to tilt rams 14, 16. An over-ride valve 154 can over-ride the valve 152 when it is actuated by a cam 208 on the forks 13. When the forks are lowered the valve 154 is operated and the mast may be tilted to set down the load. A variable displacement pump, Fig. 2, (not shown), may replace the fixed displacement pump 18 and may be controlled by the control signal conduit 102, Fig. 3 shows an arrangement in which valves 150, 152 are responsive to the pressure difference on opposite sides of the pistons in rams 14, 16.

Title: Improvements in electric relay apparatus employing thermionic valves
IPC: H03F1/50
Filed: 1923-11-12
Abstract: 228,647. Brown, W. J., Hubbard, E. J. E., Robinson, E. Y., Burch, C. R., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 12, 1923. Thermionic relays.-A time-lag relay having its coil connected in the plate circuit of a thermionic rectifying-valve is actuated by changes in current in a controlling circuit by arranging in the grid circuit of the valve a combination of a condenser and resistances or inductances, with or without a separate rectifier. As shown in Fig. 1, the operating-coil 11 of the relay is in the plate circuit of a thermionic valve 6, which has its grid circuit energized by the line current in conjunction with which the time-limit relay acts. A condenser 3 and resistance 4 are connected between the grid 5 and one end of the transformer secondary coil 2, the other end of which is connected to the filament 9 through a battery 8, which normally applies a biassing potential to the grid through resistances 7, 4. Under normal working, the mean grid potential has a value less than that required to give a mean plate current sufficient to operate the relay 11. When the line current changes, the mean grid current changes instantaneously. The potential of the grid however does not assume its new mean value until a certain time has elapsed, dependent on the capacity of the condenser 3, the resistances 4, 7 and the grid-current characteristic of the valve. The mean plate current is in step with the mean grid potential, and the relay 11 therefore operates at the conclusion of the time lag, provided that the alteration of line current is sufficiently large, and lasts for a sufficient time. When applied to direct current circuits, the condenser 3 is arranged to be charged in accordance with changes in the value of the direct current. Fig. 2 shows a modification, in which the transformer secondary coil 2 is connected through a two-electrode valve rectifier 13 and a resistance 14 to a parallel arrangement of a condenser 16 and resistance 15, the grid being biassed by a battery 17. A chain of resistances such as 14 may be used, with condensers connected from each junction point of the resistances to the filament end of the transformer 1. Fig. 4 shows another modification, in which the transformer secondary coil is connected across the grid and filament of a three-electrode valve 23, the plate circuit of which includes a battery 27, resistance 2R, and resistance 15 shunted by a condenser 16. The grid of the valve 6 is connected to a point between the resistances 28, 15 and is biassed as before by a battery 17. The valve 23 may be adjusted so that under normal conditions no plate current is flowing, but with a slight increase in the line current through the transformer 1, the mean anode current may become large, and after the delay period has elapsed, the mean grid voltage of the valve 6 is raised, and the relay 11 operates.
