Title: Improvements in or relating to apparatus for the electrical protection of gaseous discharge-tube installations
IPC: H05B41/46
Filed: 1938-01-10
Abstract: 496,083. Protective cut-out arrangements. BARLOW, H. E. M. Jan. 10, 1938, No. 677. [Class 38 (v)] An electric protective device for gaseous discharge tubes comprises, in series in the discharge-tube circuit, an electromagnetic relay which is energized, immediately current flows through the tube, to maintain closed a normally-closed switch or other circuitbreaking device through which power is supplied to the tube and operating automatically, as a result of de-energization, to cause or permit said switch or device to open and interrupt the supply to the tube when the voltage applied to the tube is reduced below the value required to produce or maintain the discharge. In the drawing, two relays are employed having windings U<1>, U<2> connected on either side of the earth connection E between the halves of the secondary S of the transformer supplying the tube N and windings W<1>, W<2> connected in parallel or series with the primary P or, as shown, in series with an additional winding X linked with the primaryflux. A pair of armatures C<1>, C<2> remain normally in the position shown, to which they are manually moved after operation of the device. If a secondary earth-fault occurs on the left side of E, and the resulting heavier loading of that side of the secondary reduces the secondary voltage sufficiently to stop the discharge of the tube, no current flows in the right side of the secondary and winding U<2>, hence W<2> attracts C<2> and the latter engages stop F and rocks the mercury switch D about spindle H to open the primary P. As the winding U<1> carries the leakage current, the armature C<1> is not attracted, but with an earth fault on the right side of E, U<1> is de-energized and W<1> attracts C<1>. With an open-circuit on the secondary, both windings W<1>, W<2> attract their armatures. Instead of operating a mercury switch, both armatures may bridge mercury contacts or may fracture fuses in the primary or shortcircuit the primary to blow fuses therein. One relay may be placed vertically over the other with the two armatures on the same vertical spindle, the electromagnets W<1>, W<2> being then combined into a single unit operating jointly on the armatures. When the secondary is earthed at one end, a single differential relay has its winding U placed in series in the circuit at the point which is at earth potential. When several tubes are connected in series, the winding U of a single relay can be connected in series in the circuit at the point which is at earth potential, or alternatively, such a discharge tube circuit may be placed in parallel with a main dischargetube circuit and have a winding U connected therein at the earth-potential point. Whether or not a transformer is employed, or a D.C. source, interrupted or otherwise, supplies the discharge tube, the winding W may be connected across the supply.

Filed: 1929-01-08
Abstract: 327,728. Davies, D. N., and Bakelite, Ltd. Jan. 8, 1929. Compound sheet materials.-Coated metal sheets for earthed panels for electrical apparatus are made by laying a metal screen, for example sheet metal perforated. deformed or superficially striated, on to a layer of non-conducting material coated or impregnated with a potentially reactive synthetic resin and pressing the superposed materials at a sufficient temperature and for a sufficient time to cause the resin to flow and ensure good union between the metal and the non-conducting material and thereafter to harden and become infusible. Preferably the non-conducting material consists of cotton cloth impregnated with 60 per cent of its weight of a phenol-urea-aldehyde resin, or of layers of mica bonded with a reactive phenol-urea-aldehyde resin such for example as that described in Specification 302,612. In one method, sheets of paper impregnated with Bakelite varnish and dried are superposed and interleaved with one or more sheets of metal foil such as aluminium, tin or copper, 5/1000 ths of an inch thick, perforated with 3/16 th inch holes with centres ¢ an inch apart. The material is then consolidated under heat and pressure. Wire gauze or a screen consisting of independent wires may be used in place of metal sheets. One side of the material may be polished and finished to imitate wood or marble. Electrical contact. with the metal layer may be made by drilling and tapping the sheet and inserting a set-screw, or a corner of the sheet may be sawn away to expose the metal for soldering.

Title: Improvements in or relating to radar display apparatus
Inventor: COLCHESTER CHRISTOPHER DERING
IPC: G01S7/22
Filed: 1949-01-13
Abstract: 677,994. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 27, 1949 [Jan. 13, 1949], No. 999/49. Class 40 (vii). A radar system having a p.p.i. display comprises electrical means to cause the beam of the c.r.t. to produce additionally a rectilinear grid network whose scale and position is automatically maintained in correspondence with the normal radar display on the tube screen. Three oscillators VO1, VO2 and FO are triggered into oscillation by signals over line L1 such that they oscillate for the periods of each line scan only. The oscillator FO is fixed in frequency such that its period is of the order of one-tenth of the echo time for the range between the required grid co-ordinates, e.g. 150 Kc/s. would be suitable for a grid spacing of 10 kilometres. The oscillators VO1 and VO2 are variable in frequency about that of FO as a mean by a maximum amount that determines the grid spacing, e.g. 15 Kc/s. for 10 Km. spacing. The variation is controlled by the aerial scanning as indicated diagrammatically by magslip M coupled by chain lines CH to variable condensers Cl, C2; the drives and frequency-varying elements are such that at any position of the aerial the difference in frequency between VO1 and FO is, for the example of 10 Km. grid spacing, 15 sin # Kc/s. and between VO2 and FO is 15 cos # Kc/s., where # is the angle between the aerial direction and grid north. The oscillator outputs are fed to mixers M1, M2 and the sine and cosine outputs obtained are fed respectively through low-pass filters LPF1 and LPF2 to control pulse generators SPP1 and SPP2 which produce short pulses at intervals (for the example) of 1/15 sin # and 1/15 cos # milliseconds respectively. These pulses are fed, together with normal radar signals from line L2, to the p.p.i. circuits S and cause the tube to trace out the required grid on its screen as the aerial rotates. The station may not be situated on lines of the desired grid network so variable phase shifters PS1 and PS2 are inserted as shown to enable the co-ordinates of the station to be introduced, PS1 giving N and S adjustment and PS2 giving E and W adjustment. In the case where the station lies on a grid line and the corresponding phase shifter is accordingly set at zero this grid line would not be drawn and therefore switches S1 and S2 are provided to close at the N and S, or E and W positions of the aerial respectively and cause the production of a bright line (in the known manner of displaying a ship's heading marker), but only when the associated phase shifter is set at zero. Removable grid windows may be provided to place over the p.p.i. merely to identify the electronic grid lines and do not need accurate alignment with the display.
