Title: Improvements in or relating to thermionic valve circuits
IPC: H03K21/00
Filed: 1944-12-30
Abstract: 587,655. Valve counting circuits. TAYLOR, S. M. Dec. 30, 1944, No. 26191. [Class 40 (v)] In a valve counter circuit for delivering a pulse coincident with the last of a group of regularly recurring input pulses, a group of resetting pulses of equal recurrence frequency is generated for comparison with the input pulses, each resetting pulse being prevented from stopping the counting sequence when it coincides with an input pulse. The Figure shows a radar receiver 1 feeding echo signals to the suppressor grid of biassed gating valve 2. A synchronizing pulse from the receiver locks a saw-tooth voltage waveform which is compared with an adjustable steady voltage in circuit 3,to produce a positive pulse when the two voltages are of equal amplitude. These selector pulses are made to coincide with particular echo pulses and overcome the bias on valve 2 to allow the echo pulses to pass exclusively through separator 5. to successive scale-of-2 count-down circuits 6, 8 so that a negative output pulse is fed to the indicator for every 4 echo pulses from the receiver. Each selector pulse from circuit 3 is also fed to a resetting pulse generator 11 which feeds a slightly delayed positive pulse to the control grid of gating valve 12 which is rendered non-conducting by negative pulses on the suppressor grid from circuit 6, corresponding in time to the echo signals. The resetting pulse is therefore suppressed when it coincides with an echo pulse. Chance coincidences from spurious signals of different recurrence frequency occur less than four times in succession, and at a non-coincidence a resetting pulse is transmitted by valve 12 'to the Kipp relay 14 which has a restoration time such that a negative pulse is produced after the time base period has lapsed to restore count-down circuits 6, 8 to their original condition. The positive pulses appearing at the output valves of circuits (i, 8 during the restoration process, are made non-effective by applying a bias voltage from receiver 1 to the suppressor grids of the output valve 7 and its counterpart 8 during the rest periods between time bases. Specifications 581,996 and 582,169 are referred to.

Title: Improvements in or relating to steam power plants
IPC: F22B35/10
Filed: 1930-09-03
Abstract: 361,990. Feedwater regulators for steam-boilers. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Doble Steam Motors, Ltd. ; 4053, Harlan Street, Emeryville, California, U.S.A.) Sept. 3, 1930, No. 26304. [Class 123 (ii).] An electrically-controlled steam-boiler plant comprises a thermostatically-operated switch for controlling successively the feedwater and fuel supply and a pressure-operated switch for interrupting the operation of the entire plant when the pressure of the steam in the boiler exceeds a predetermined value. On starting up the boiler 2, a switch 58 is closed and current flows from a battery 56 to the motor 16 which drives the fan 17 to deliver air and fuel. As the temperature of the boiler rises, and steam is generated, a thermostat 23 in the steam space of the boiler operates a switch lever 25 to open normally closed contacts 30, 33 in the circuit of the solenoid 57 and thus de-energize the latter to open the valve 15 to permit feedwater to pass from the tank 13 to the pump 3, which is also driven by the motor 16, and be supplied through the valve-controlled pipe 7 to the bottom of the boiler. Further rise in temperature of the boiler causes the thermostat to operate the lever 25 to close contacts 31, 34, energize the solenoid 56a and open the valve 10 to permit feedwater to flow to the steam space of the boiler through the pipes 9, 11. Should this supply of feedwater be insufficient to lower the temperature to that desired, the switch lever 25 is further operated to close contacts 39, 40 and permit current to flow to a solenoid 55 to close a valve 54 in the conduit 18 and thus stop the fuel supply. In the event of the pressure in the boiler exceeding a predetermined limit, a spring-pressed diaphragm 46 operates a switch 49 and breaks the circuit of the motor 16 and other electrical apparatus in the system. The counter contacts 33, 34, 40 of the thermostatically operated switch are mounted on pivoted levers adapted to yield against the action of springs.

Abstract: 482,449. Winding - gear. SMITH, G. D., GEORGE, H. N., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 29, 1936, No. 26452. Drawings to Specification. [Class 78 (v)] A winder equipment for mine hoists &c. is provided with control means actuated when the ascending cage has reached a position slightly above the keps to cut off the supply to the winder motor or engine and cause partial application of the brakes, allowing the cage to settle upon the keps, together with a second control means actuated when the cage rests upon the keps to cause immediate full application of the brakes, and after a brief time interval a momentary release of said brakes to take up any slack in the rope. The kep may be any support which does not obstruct upward movement of the cage but holds it against downward movement until it is withdrawn or tripped, usually by a manual operation. Preferably the brakes normally assume the " on " position and are held " off by a brake actuating device, whilst an auxiliary actuating device which serves partially to release the brakes is rendered operative during the time that the cage is settling down on the keps. The subsequent momentary release of the brakes to take up slack in the rope may be effected by a time delay device which is set when the first winder control is actuated and released when the cage rests on the keps, so that it momentarily operates the main brake after a, short interval. The winder may be driven by electric motor, steam engine. &c., and the brakes may be electrically or hydraulically actuated. Specification 482,448 is referred to.

Abstract: 954,311. Drying granular material. VEREINIGTE GLANZSTOFF FABRIKEN A.G. July 21, 1961 [July 23, 1960], No. 26560/61. Heading F4G. A process for the continuous drying of granular material, e.g. shredded organic high polymers, comprises continuously supplying the material to a shaft drier in which it is traversed in two separate zones by a drying gas, a larger heated component stream being connected to the upper zone and a smaller, cooled and regenerated component stream being supplied to a lower zone to dry the material heated in the upper zone, the smaller stream mixing with the larger stream beneath the upper zone and flowing therewith through the upper zone and being exhausted therewith. Granular material is dried by passage through a shaft drier in countercurrent to an upper, heated stream of gas, e.g. nitrogen, and a lower cooled, dried gas stream introduced at 20, 18 into upper and lower zones respectively. The material passes into the drier through a pipe 1 and distributer 3 for passage through funnels 6 in a plate 5 having lower tube sections 7 which extend through an intermediate plate 8 and further passage through a space below the tubes 7 having a cooling coil 12. The dried and cooled material is collected in hoppers 13 for removal through openings 14, 16 for withdrawal at B. The larger heated gas stream enters a cavity 21 formed by the walls of the funnels 6, tubes 7 and intermediate plate 8 for passage through apertures 9 in the tubes 7 and upward passage through pipes 10 concentrically mounted within the tubes 7 and funnels 6, the mouths of the pipes 6 being covered with deflecting caps 11. The cooled gas enters at 18 into a space 19 formed between the pipes 7 and rises therethrough and through the funnels 6 in countercurrent to the heated material falling therethrough and mixes with the heated gas stream for exhaustion through an aperture 46. The combined streams pass through a cyclone separator 22 and fan 23 and are then separated, the larger stream passing through a heater 26 before reintroduction to the drier and the smaller passing via a condenser 28, water separator 29, oxidizing apparatus 31, and preferably a further condenser 37 and separator 38, to the inlet 18. The regulation of both the total quantity of the drying gas which is kept in motion and the quantity of gas in the smaller stream is effected in dependence on the pressure in the dryer and/or the quantity of moisture taken up by the smaller stream.
