Title: Improvements relating to electrical control systems involving mercury arc discharge devices for use more especially in connection with the absorption of regenerated power
IPC: H02P3/12
Filed: 1941-04-25
Abstract: 548,946. Converting. ELECTRIC CONSTRUCTION CO., Ltd., and MILNE, J. C. April 25, 1941, No. 5329. [Class 38 (ii)] In an arrangement for connecting a loader resistance X across a D.C. circuit L+, L- in response to rise in circuit voltage, e.g. on regenerative braking in a traction system fed by rectifiers, a mercury arc discharge device A is connected in series with the resistance X across the mains and is rendered conductive by a positive impulse applied to a control grid Gr, the impulse being derived from the circuit of an auxiliary anode T or a separate valve which is rendered conductive by application of positive voltage to its grid Gt when the voltage of the circuit L+, L- increases by a predetermined amount. The circuit voltage is applied to a potentiometer P and a proportion thereof, determined by a tapping p, is applied in opposition to negative bias from an auxiliary rectifier B1 to the grid Gt. The circuit of the anode T, controlled by the grid Gt, is energized from a transformer secondary S1, or, to ensure instantaneous response, from a condenser maintained charged through a rectifier, and includes the primary of a transformer T2 the secondary of which provides the positive impulse which overrides a negative bias provided by a rectifier B2 on the grid Gr. A relay system (not described) is associated with the circuit of the main anode for disconnecting the resistance X by extinguishing the arc when the circuit voltage returns to normal. In a modification, Fig. 2 (not shown), a plurality of loader resistances are connected in parallel through a discharge device having a corresponding number of main. anodes. Specification 502,568 is referred to.

Abstract: 383,825. Seat and table &c. adjustments. STOLL, A., Waldshut, Baden, Germany. Feb. 23, 1932, No. 5407. Convention date, Feb. 26, 1931. [Classes 52 (ii) and 52 (iii).] A resilient pedestal adjustable in height forfurniture such as chairs and tables consists of a pair of telescopic tubes 2, Fig. 1, carrying the seat &c. and sliding in a guide 3 in a stem 1 to which the foot 8 is attached, the tubes 2 and stem 1 being resiliently connected by a spring 4 disposed in the annular space therebetween. The spring 4 engages between a flange on the outer tube and a thrust ball bearing 5 resting: in a lower guide bush 6 which is supported by a ring 7 in the stem 1, all the parts within the stem except the ring 7 being removable. The legs of the foot 8 are, in the construction shown, of metal and of U-section and have flanges 9 which engage in a socket 12 on the stem 1 and flanges 10 engaged by a cap 11 secured by a nut 13 which screws on the bush 6. Vertical adjustment of the seat is obtained by sliding the inner of the telescopic tubes relatively to. the outer, the tubes being fixed in adjusted position by a transverse bolt passing through a hole in the inner tube and engaging in one of a series of holes in the outer tube. The bolt is operated by the engagement of lateral projections 21 thereon in an inclined groove in a spring-loaded plunger 17 operated through a Bowden wire 19 from a handle 18. A modified form, Fig. 2, has wooden legs 8<1> secured by screws between ears 14 on sleeves 15 which may be welded to the stem 1, or the lower sleeve 15 may be detachably secured by cotter pins &c. to allow removal of the legs 8<1>.

Abstract: 542,496. Cathode-ray tubes. McGEE, J. D., MILLER, H., and FREEMAN, G. S. P. May 2, 1940, No. 5440/41. Divided out of 542,488. [Class 39 (i)] In cathode-ray tubes of the kind in which the beam of electrons is focused by a magnetic field parallel to the direction of the beam, as described in Specification 530,409, stop electrodes are disposed along the beam so as to intercept some of the electrons with undesirably large radial velocities. In the preferred arrangement, two stop electrodes 1, 2 are spaced apart so that electrons originating at or in front of the electrode 1 have their maximum lateral displacement at the electrode 2. Dimensions are given for specified operating conditions. According to a modification referred to the stop electrodes may be replaced by a tube or block with a bore of corresponding size.

As shown, the device a comprises a pair of pistons D, each inwardly urged to a central position by a respective coiled spring A. On upward deflection at the centre of the spring, tending to separate the two pistons D, liquid or air contained in the cylinder can only flow from one side of each piston to the other, through small passages d. On rebound, the pistons are returned to a central position by the springs a, and liquid flow also occurs through larger passages d<SP>1</SP> controlled by non-return valves d<SP>2</SP>.

Class 75(1) [Also in Group XXVIII] In a vapour fuel generator for the combustion system of a gas turbine engine having an auxiliary combustion chamber supplied with air and fuel so proportioned as to ensure that there is no uncombined oxygen in the effluent therefrom, as described in Specification 712,843, the main fuel supply is ejected into the effluent through a valve arranged to open only when the pressure of the main fuel has attained a predetermined value the value comprising a nozzle which in conjunction with a tail pipe of the auxiliary combustion chamber ensures that the ejector action due to the flash vaporizing of the main fuel in the effluent gases promotes the flow of the effluent gases from the auxiliary combustion chamber, for example as when a very low pressure drop exists in the main combustion system. As shown, an auxiliary combustion chamber 13 is supplied with air from the engine compressor through a conduit 11 and duct 14 into a mixing chamber 15 fed also with fuel through a pipe 17 in jet form, the mixture emerging through a sharp-edged orifice 16 in the up-stream direction to be ignited by igniter 18. The hot combustion gases pass into the tail pipe 19 to preheat the main fuel in coil 20 which is fed under pressure, partly through a spiral passage 23 surrounding, to cool the chamber 13 and directly through a pipe 24, in dependence on a control 22. The end of the coil 20 is equipped with a spring biased needle valve 34 disposed to eject the main fuel into the converging end of a mixing chamber 32, the outlet area of the needle valve being controlled by the pressure of the fuel in conjunction with the spring bias pressure of the valve (see Group XXVIII).
