Filed: 1927-01-14
Abstract: 264,518. British Thomson-Houston Co., Ltd., (Assignees of Devers, P. K.). Jan. 14, 1926, [Convention date]. Sparking-plugs.- An insulator consisting of a sleeve 1 of fused silica or other refractory material is held under compression by a metal casing 7 consisting of a material having a higher coefficient of thermal expansion than the silica. The silica is first provided with a very thin coating of silica by chemical reduction, using a solution of silver nitrate, ammonium hydroxide, and a weak reducing liquid such as sodium or potassium tartrate. A layer of nickel is then deposited electrically upon the silver, and the coated tube plunged into a bath of molten copper, or copper alloy 3. The dipping is repeated until the required thickness is obtained. A plug 6 of graphite or the like prevents the molten liquid from entering the base 5 of the insulator. The copper shell is then trimmed and screwthreaded, and a sparking terminal 9 is attached. The central electrode is smaller in 'diameter than the bore of the insulator, and has an enlargement 11 which, by grinding or otherwise, is adapted to be brought into gastight engagement with the inner end of the bore 5. In a modification the insulator is externally tapered, and does not extend the full length of the shell 7.

Abstract: 514,294. Automatic control of voltage. STANDARD TELEPHONES and CABLES, Ltd., THOMAS, P. R., and KELLY, R. April 26, 1938, No. 1219/39. Divided out of 514,167. [Class 38 (iv)] Relates to systems for' automatic regulation of the voltage across a load circuit of the kind in which the supply is regulated by a motordriven element which is set in motion whenever the voltage across the load circuit varies from the desired value. Whenever the circuit controlling the motor and its direction of drive is closed a clutch is operated to cause the regulating element to be driven from the motor shaft and a brake removed from the regulating element, and when the circuit is broken a brake is applied to the element and it is declutched from the motor shaft. In the arrangement shown direct current is supplied to the load LC by A.C. mains through variable transformers VT and rectifiers R. The capacitor type motor with its two coils M1 and M2 is energized from a phase of the A.C. mains to move contact points connected to tapping points of the variable transformers to vary the voltage supplied to the load. the motor circuit being controlled by a winding VC connected across the load and acting to move contact member SV1 to close contacts L or H according as the voltage is below or above the desired value, relays being thereby energized to complete the motor circuit and operate the clutch and brake. The clutch and brake employed are preferably those described in Specification 201,256, [Class 103 (i)]. Chattering of the contacts of switch SV1 is prevented by means of auxiliary contacts for removing a short circuit from a resistance R3 to reduce current in coil VC when contact L is made and to short circuit resistance R2 when contact is made. Specification 514,167 also is referred to.
