Filed: 1941-10-28
Abstract: 552,996. Thermionic relay circuits. BRITISH POWER BOAT CO., Ltd., and PARFITT, P. Oct. 28, 1941, No. 13884. [Class 40 (v)] A thermionic relay circuit comprises a relay coil 20 in the anode circuit of a valve 10. A time delay is introduced due to the time taken for the cathode 11 to heat up after closure of a switch 15 in the circuit of a heater 12, the length of the delay being variable by a resistance 14. Alternatively, the delay may be due to the time for the cathode to cool after opening switch 15. The circuit may be stabilized by a negative grid bias applied through resistance 17, or the valve may be arranged to oscillate in which case the relay 20 is tuned to the same frequency.

Title: Improvements in high-speed electrical disconnecting devices
IPC: H01H9/44
Filed: 1955-05-13
Abstract: 773,386. Automatic circuit breakers; arcrupturing in switches; actuation of switches EMAG ELEKTRIZITATS-GES. May 13, 1955 [May 22; 1954], No. 13902/55. Class 38(5) In a switch, a main current path 1, 4 is interrupted by a chemical energy source which also initiates the interruption of a parallel secondary current path 7, 8 in which final disconnection occurs by elongation of the arc produced therein. In Fig. 1 the main current path 1, 4 extends through an explosive conducting cartridge 5 and is broken on the firing  of the cartridge. The detonation momentarily increases the contact pressure between a bridging contact 9 and contact members 7, 8, before a spring 16 moves the contact 9 down to open the parallel path. The arcs drawn between the contacts 7, 9, 8 unite and the resulting arc is blown along arc runners 10, 11 by magnetic blowout device 12, 13 and elongated by an insulating partition 17. In other arrangements the main current path is broken on the explosion of a charge fracturing a conductor (Fig. 2, not shown) or opening a bridging contact against the bias of a spring. In the latter case the bridging contact is latched in the open position (Fig. 3, not shown). The parallel secondary path may have two breaks with oppositely poled blow-out coils and be so arranged that only the break having the correctly polarized coil for the current to be interrupted is opened.

Abstract: 716,396. Coke oven bracings. WOODALLDUCKHAM VERTICAL RETORT & OVEN CONSTRUCTION CO. (1920), Ltd. May 19, 1953 [June 5, 1952], No. 14275/52. Class 51 (2) In a coke oven battery having regenerators disposed beneath the coking chambers and main buckstays 1 extending over the full height of the oven, an auxitiary buckstay 7 is adjustably mounted on some at least of the main buckstays in the region of the ovens themselves, so that each auxiliary buckstay lies between a pair of adiacent ovens and bears against the side flanges 14 and 15 of a pair of adjacent oven door frames 16 and 17. The main buckstays 1 comprise I-girders mounted midway between adjacent ovens and each auxiliary buckstay 7 comprises two channel members 8 and 9 enclosing the inner flanges 5 and a considerable section of the web 3 of a main buckstay, said channel members being connected by top and bottom bridging plates 19. and 20 of part circular cross-section engaging the flanges 5. At about the level of the bridging plates, the web 3 of the main buckstay is formed with an upper slot 25 near the inner flanges 5 and a lower slot 24 near the outer flanges 23- and bolts 21 and 22 carrying inner spacing sleeves 27 pass through these slots and through circular holes in the channel member 8 and key-hole shaped slots 28 and 29 in the channel member 9 to hold the buckstay assembly together. Ramps 30 are welded to the lower inner side of each flange 23 of the main buckstay and are engaged by wedges 31. The lower end of the auxiliary buckstay wiil thus tend to swing towards the battery about the bridging plate 19 as fu'crum, and i the main buckstay bows in use the wedge 31 will drop or is driven between the ramp 33 and the auxiliary buckstay flanges 10 and 12, thus keeping said auxiliary buckstay in contact with the oven door frames. In modifications, Figs. 7 and 8 (not shown), the wedges are urged downward'y by vertical screws threaded in lugs on the auxiliary buckstays or by coiled springs respectively. In a further modificaton, Fig. 10, the ramps and wedges are replaced by adjusting screws 37 screwed into bosses 38 on the flanges 23 with their heads contacting the flanges 10 and 12 and a final modification, Figs. 11 and 12 (not shown), has laminated leaf springs between the flanges 23 and the flanges 10 and 12.

Patent GB-578432-A (GB)
Title: Monitoring arrangement for frequency modulation signal generators
IPC: G01R29/06
Filed: 1944-07-27
Abstract: 578,432. Monitoring frequency modulation. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. July 27, 1944, No. 14385. [Class 40 (v)] [Also in Group XXXVI] The change in direct anode current of a reactor valve, when the modulation voltage is constant, is a direct measure of the deviation in the frequency of the oscillations and is used to monitor frequency or phase modulation signal generators. In Fig. 1, the suppressor: and screen grids of the reactor valve V have their normal connections. The anode is connected to a source of positive potential through a high-frequency choke L2 and a direct current indicator I in series, and is also connected directly to the tank circuit of the carrier wave generator (not shown). This tank circuit is also connected through a phase-splitting circuit P, and condenser Cl to the control grid of the valve V, thus producing a voltage on the grid which is 90 degrees out of phase with the anode potential. The modulation potential from a source M is fed to the grid in series with a bias source B through the high-frequency choke L1. The circuit may be in the form of a bridge as in Fig. 2, resistances R, Rl and valves V, V1 forming the four arms, the.current indicator I being connected across one diagonal, and a source of direct potential across the other. Valve V is otherwise connected as in Fig. 1, the screen of valve V1 is connected to that of valve V and the control grid of the valve V1 is connected to the junction of sources B, M. Such an arrangement of resistors R1, R and valve V1 balances out the steady component of the anode current of the valve V, the current through the indicator I being a measure of the deviation of the frequency of the carrier wave. In order that the modulation voltage may be kept constant, indicator I is also switched to a rectifier so connected as to measure the alternating component of the voltage.

Title: Improvements in and relating to self-balancing laundry and dry-cleaning machinery
Inventor: ARAM ERIC HAROLD GEORGE
IPC: D06F37/22
Filed: 1952-06-09
Abstract: 748,077. Centrifugal drying apparatus. MANLOVE, ALLIOTT.& CO., Ltd. June 9, 1953 [June 9, 1952; Sept. 24, 1952], Nos. 14485/52 and 23966/52. Class 34(2). The driving shaft of a centrifugal basket 16 is driven through a V-belt drive 18 and a clutch 14 and is journalled in a spherical self-aligning roller bearing 20 and a flexible bearing 22. The end of the shaft runs in a fixed sleeve 28 having ports 30, 32 for supplying air to the clutch operating plunger 40 and passages 42 respectively. Each passage 42 leads to a control pipe 44 through a nozzle 45 in a casting 46 which rotates with the shaft and has vents 47 therein controlled by spring-loaded balls 48. A balancing drum 56 is fixed to the basket 16 and comprises three chambers 58 interconnected by an equalising chamber 62. The chambers have internal passages 63 formed with openings 65, 66 providing communication therebetween. Each chamber is supplied with air through a passage 68, a passage 72 controlled by a valve 74, a passage 90 and an inlet valve 70. The air from each passage 44 is led by a pipe 76 to a balance cylinder 78 containing a liquid-filled and weighted bellows 80 which is connected by a pipe 82 to a cylinder 84 containing a bellows 86 for controlling the valve 74. When out of balance forces arise the shaft and the casting 46 will rotate eccentrically relative to a mounting ring 26 thereby opening or closing the vents 47 and varying the pressure in one or more of the pipes 44. When the pressure in the pipe 44 is increased it will expel liquid from the bellows 80 into the cylinder 84 thereby opening the valve 74 to permit a flow of air into a cylinder 92. The cylinder 92 contains bellows 93, 94 having holes 96, 97 communicating with the pipe 90 and the atmosphere respectively. The bellows 93 has a valve seat 98 adapted to close a passage 99 communicating with the atmosphere through an orifice 100 and with the balance chamber 58 through a pipe 101 and a valve 102. The inlet valve 70 is normally closed by centrifugal force whilst the outlet valve 102 is normally kept open thereby. As the pressure builds up in a cylinder 92 the bellows 93 is first collapsed to close the passage 99 and then the bellows 94 is collapsed to open the valve 70 and permit a flow of air into the associated balance chamber 58. The balance chamber at one end of the basket is connected to corresponding chambers by suitable conduits. At the other end the basket is provided with a balancing drum 108 which is similar to the drum 56 and is provided with a valve 110 corresponding to the valve 102 but without any of the control devices of the drum 56. When the valves 102, 110 are open the associated chambers of the two drums communicate through a pipe 112 which passes through the beaters 114 of the washing machine.
