Abstract: 473,363. Interrupters. ELLIOTT, A. G., and ALLWOOD, F. F. April 15, 1936, No. 10845. [Class 38 (v)] An ignition timing arrangement comprises a contact breaking cam adjustable on a driving shaft in steps or stages and a tine adjustment to the extent of a step or stage provided between the rocker casing and a member which moves the casing circumferentially to advance or retard the ignition. As shown in Figs. 1-4. the interrupter cam C is formed with a series of internal teeth C<1> which fit over corresponding teeth B<4> on the driving shaft B<1>, the latter having a tapered end portion B<2> against which the cam is held by a screw B<3> so that the position of the cam may be altered to the extent of one or more teeth by releasing the screw B<2>, sliding off the cam and sliding it on again in a displaced position. The upper portion of the cam carries the distributer electrode holders. To permit timing adjustments between that which is determined by the pitch of the teeth on the cam, the casing A<1> carrying the contact rockers is adjustable relatively to the ring B fitted with the usual manuallyoperated control rod M. This adjustment may as shown be effected by inter-engaging teeth on the casing A<1> and on a wheel F<1> carried by a pin D pivoted to the ring B and carrying an adjusting lever F<4>. Alternatively, Fig. 9 (not shown) an eccentric adjustment may be employed.

Title: Improvements relating to the protection of electron discharge devices
IPC: H01J41/02
Filed: 1948-04-22
Abstract: 638,545. lonisation gauges. BRITISH THOMSON-HOUSTON CO., Ltd., WATT, I. M., and MILNER, C. J. April 22, 1948, No. 11108. [Class 37] [Also in Group XXXVII] A device having an electron-emitting electrode subject to deleterious gases at variable pressure, such as an ionisation gauge 1 which has an electron-emitting electrode 2, a positively charged grid 4 and a negatively charged positive ion receiving electrode 3, is protected in the event of the pressure in the gauge rising so as to cause excessive positive ion current due to the " poisoning " of the electrode 2. The electrode 2 is connected to the positive side of the D.C. supply from a rectifier 6 through a meter 10 and the resistor 9 of a potential divider 9, 13 and is heated from the A.C. supply 5 by means of a filament transformer 14, the heating current being maintained substantially constant by means of a choke 15 having a saturating winding energized by means of valves 16 arranged in "push-pull" with the potential of their control electrodes determined by the volt drop in a resistor 17 connected in series with the grid 4. The negatively charged ion receiving electrode 3 is connected via ion current meter 11 and resistor 12 to the negative of the D.C. supply, the volt drop across the resistor 12 being applied to the control grid of a pentode 19 having its anode connected in series with the operating winding of a relay 18 which has normally closed contacts. To bring the gauge 1 into operation, a push-button switch 23 is actuated to complete a circuit through the contacts of relay 18 and resistor 22 for the operating winding of a relay 21, which closes its contacts 25, 26 to complete circuits for the heater current and for the grid 4. On release of the push-button, the relay 21 remains closed as its winding is now in series in the grid circuit and is energized by the electron current. Should the positive ion current become excessive, the volt drop across resistor 12 is sufficient to cause the pentode 19 to energize the relay 18, which opens its contacts, so de-energizing the relay 21 which opens to render the gauge 1 inoperative until the switch 23 is reclosed. In the event of the electrode 2 becoming " poisoned " the reduced electron current is insufficient to hold the relay 21 closed, so the relay opens and renders the gauge inoperative.

Abstract: 356,693. Transformers. KOCH & STERZEL AKT.-GES., 40, Zwickauerstrasse, Dresden, Germany. April 8, 1930, No. 11208. Convention date, April 30, 1929. [Class 38 (ii).] In a voltage transformer for use on high tension circuits, the high tension winding 12, Fig. 3, is arranged on an insulating spool 11 and the connection to the high tension line is brought out through the flange of the spool from the inner layer of the winding so that the potential of the layers decreases from the inside to the outside of the winding. The inside and outside surfaces of the spool are separately metallized to form condenser elements which are connected respectively to the high potential and earthed ends of the winding. The leading-out insulator 17 may be formed integrally with the flange of the spool and may serve as housing for a replaceable fuse 27, Fig. 8. In this form the spool body is formed with an extension 26 enclosing the upper yoke 24 of the core. Other forms of spool body are described in which the leading-out insulator is located concentrically. In another form, Fig. 7 (not shown), the spool carrying the windings is immersed in an oil tank and a separate oil-filled leading-out insulator is provided on the cover of the tank. The high tension winding is surrounded by a metal jacket 19 which is electrically interrupted by insulating material introduced between the folds of the seam. The jacket may be secured to a base 30, or a fixing flange may be secured to the upper part of the jacket. Alternatively, a cover provided with suspension means may be secured tothe jacket, the lower part of the spool body being formed as a suspension insulator for the high tension line. Fig. 16 shows a modified arrangement of the high tension winding in which the centre point is at earth potential, and the two parts on opposite sides thereof are arranged on opposite sides of a centre rib formed on the spool body. A plurality of winding units of the type shown in Fig. 3 may be mounted on a common iron core for use on polyphase systems. Cascadeconnected arrangements are also described, Fig. 20 being one example in which the winding in the upper unit is arranged in accordance with the invention, whilst the winding in the lower unit has its innermost layer at earth potential. The metal jackets surrounding the two winding units are connected so as to form overcoupling windings. In other cascade systems, Figs. 17 and 19 (not shown), the units are designed as suspension elements in a chain insulator for the high tension line.
