Title: Improved apparatus for the electrostatic separation of matter
Inventor: MAAS FRIEDRICH JULIUS
IPC: B03C3/38
Filed: 1956-10-08
Abstract: 842,147. Electrostatic precipitation. SOC. FINANCIERE D'EXPANSION COMMERCIALE ET INDUSTRIELLE S. A. SFINDEX. Oct. 8, 1956, No. 30664/56. Class 39(1). [Also in Group XX] An electrostatic precipitator has an ionizer chamber in which is located a radioactive emitter 19, Fig. 3, radiating downstream and a surrounding tubular electrode 21, and the gas is fed through the apparatus under pressure. The collecting electrode system 16 is disposed in the annular space between the insulating tube 17 and the pressure housing 6. Where the gas contains moisture the insulating tube 17 may consist of water-repellent material such as silicon glass. A further electrode 22 is provided downstream of the radioactive emitter and the voltages between the emitter and the electrodes 21 and 22 are adjusted so that the whole crosssection of the tube 17 contains ions even though the radius of the tube may be greater than the range of the radioactive emitter. In another embodiment, Fig. 2, a number of radioactive emitters 23 are disposed within hexagonal tubes 24 which together form a honeycomb structure. A further electrode may be constituted by the front of the collecting system 9. Power is supplied to the collecting system by spring contacts 32 and to the ionizer electrodes over a voltage divider 29. The gas may be cooled and then expanded before entering the apparatus to facilitate condensation of moisture on the dust particles.

Abstract: 748,020. Automatic temperature control systems. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Nov. 30,1953 [Dec. 3, 1952], No. 30720/52. Class 38 (4). [Also in Group XL (b)] Apparatus for detecting and controlling temperature of hot gases flowing through a duct comprises a radiation emitting body mounted within the duct and arranged to be heated by hot gases flowing through the duct, and a radiation pyrometer outside the duct receiving radiation from the body. As shown (Fig. 1), a tube 12 of aerofoil section so as not to impede the flow of gases projects into the duct 13. The end of the tube is closed and being heated by the gases emits radiation which is received by a radiation pyrometer 11. This pyrometer may operate an indicating or recording device or, as shown in the Figure, may energize a relay 24 through control apparatus 23. This relay then controls by means of a valve 25 the supply of fuel, to afterburners 18 situated upstream of the pyrometer to increase the supply of fuel if the temperature falls and vice versa. In a modification (Fig. 4, not shown) the nozzle opening of the jet pipe is controlled at the same time as the supply of fuel to the after-burners. In a further modification (Fig. 3, not shown) the radiating body is situated wholly in the duct and is of aerofoil section so as not to impede the gas flow. The radiation from the body passes through a quartz window to the sensitive element of the pyrometer. Pyrometer details (Fig. 2).-The sensitive element of the pyrometer may be a photo-cell or, as shown, a thermocouple 21. The couple is situated at the focus of a concave mirror 33 which is provided with a hole 34 to facilitate focusing by moving the end of the casing 31 carrying the mirror. The other end of the casing is thermally insulated from the wall of the duct by a pad 30 and adjacent the end of tube 12 is a quartz window.

Title: Improvements in or relating to means for preselecting the time interval between the s
Inventor: BENNETT ALAN REGINALD HENRY
IPC: G04F3/02
Filed: 1959-09-11
Abstract: 860,222. Timed control of electric circuits. BROOKHIRST IGRANIC Ltd. Sept. 11, 1959, No. 31059/59. Class 118. A device for preselecting the time interval between the starting and stopping of a function comprises two coaxially-rotatable elements, one of which in a particular rotary position starts the function and the other of which similarly stops the function and between the two elements a gear device whereby the two elements are driven at equal speeds in opposite directions, said gear device being arcuately adjustable about the axis of rotation in order to vary the time interval between the starting and stopping of the controlled function. A bevelled driving- wheel 17 (Fig. 1) fixed to a driven shaft 30, has mounted on it a striker 9 which strikes a member 1 to start a desired operation, such as the delivery of a particular material. A second driving-wheel 18, freely mounted on the shaft 30, has a striker 10 which when it strikes a member 2 stops the operation. Between the two wheels is a freely-mounted timing wheel 22 having mounted on it a pinion 26 meshing with both driving-wheels 17 and 18, so that when the shaft 30 rotates in the direction shown, striker 9 rotates with it and striker 10 rotates in the opposite direction. As shown, striker 9 will start the desired operation slightly before striker 10 stops it. Rotation of the timing wheel 22 will adjust the angular relationship between the adjacent driving-wheels 17, 18, and thus the interval during which the controlled function is in operation. Three further timing wheels 23, 24, 25 co-operate with other driving-wheels 19, 20, 21, all freely rotating on the shaft 30, to control three other functions, e.g. to deliver quantities of other materials. Each timing- wheel is graduated, around 180 degrees of its perimeter, from 0 to 100% and by setting these wheels so that the four percentages total one hundred, a desired mix may be obtained. When the four timing wheels are so positioned, a contact 32 on the driving-shaft 30 and a contact 31 on the final wheel 21 complete an indicating circuit. In a practical embodiment each timing wheel is rotated by means of a manuallyoperated worm-drive and since this can not be driven by the wheel, the act of setting any timing wheel has no effect on any others, which remain stationary. The timing wheels in this construction are calibrated through 120 degrees only, allowing a gap between each of the four operations. The bevel gears may be replaced by a spur-gear on the outside rim of each driving- wheel driven by pairs of overlapping spur pinions.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1927-11-23
Abstract: 287,515. Associated Telephone &. Telegraph Co., (Assignees of Gould, R. F.). March 23, 1927, [Convention date]. Automatic exchange systems; metering. - In a zone metering system the meter is operated by a series of booster impulses in the third-wire circuit, and at each operation short-circuits a part of its winding so as to fall off when the normal grounded condition of the circuit is restored. It is stated that the part of the winding not shortcircuited may be non-inductive and that the armature is heavy. Outgoing calls are made over a repeater, Fig. 2, which includes a switch CCS which is set in accordance with the first outgoing digit to determine the charge, and all the repeaters are commoned to a set of relays, Fig. 4, which, when the called subscriber has replied, sends impulses to a boosting relay in the repeater until a charge has been recorded corresponding to the set position of the switch CCS. The relayset includes a time-controlled switch 96, 96', 96<2> for reducing the charge during slack hours. As long as any repeater is in use the wire 91 is grounded and the relay-set operates in a continuous cyclical manner as follows. Relay 101 owing to its relations with relay 100 is energized and de-energized in a regular intermittent manner and puts impulses on the wires 92, 117. The impulses on wire 117 operate the chain relays 105 - - 135 in pairs, each pair locking itself to the wire 91, unlocking the previous pair, and transferring the impulse circuit 117 to the next pair. The energization of the final pair unlocks the penultimate pair and thereby switches the impulse circuit back to the first pair, to start the cycle anew. In the course of each cycle the wires 136, 137, 138 are grounded successively from circuit 95, the wire 136 by relay 120 (or by 111 if the switch 96, 96<1>, 96<2> has been changed over), 137 by 126 (or 120), and 138 by 132 (or 126). When relay 105 is energized at the commencement of a cycle a pick-up circuit 93 is grounded from 91 over 103, 112 106 to energize a relay 70 in any repeater in which the reply relay 67 has been energized. The relay 70 locks itself (so as to be independent of circuit 93 which is opened a moment later at 103, 112 and then at 106) and each subsequent impulse in circuit 92 energizes relay 80, which repeats it as a booster impulse in circuit 32. This continues until the wire 136, 137, or 138 on which the switch CCS has been set is grounded by the relay-set, whereupon relay 75 is energized and locks itself up to stop metering operations in the repeater. The repeater includes a resistance x which is included in the outgoing circuit while the armature of the dialling relay 66 is in motion,
