Title: Improvements in or relating to code converters
IPC: H03M1/00
Filed: 1966-09-21
Abstract: 1,101,470. Selective signalling. PATWIN Inc. 21 Sept., 1966 [20 Dec., 1965]. No. 42098/66. Heading G4H. An indicator of the type in which a numeral drum 14, Fig. 2, is carried by a permanent magnet rotor 12 which aligns itself with the resultant field produced by an encapsulated stator 8, is characterized in that it is adapted to be controlled by binary coded signals without the intermediary of a binary-to-decimal code converter. The Specification shows how three pairs of diametrically opposite coils can be interconnected in various ways so as to produce twelve different resultant field positions when energized by combinations of four binary bits. These positions are used for the digits 0 to 9 and for " plus " and " minus " signs. The coils can either be wound on a stator annulus (Fig. 5, not shown) or they can be wound on salient inward extending polepieces (Fig. 11, not shown). The stator could have twelve salient polepieces (Fig. 13, not shown) six not carrying windings and serving merely to concentrate the field. The indicator can be so arranged that the rotor stays in its set position when the control signals are removed, by the use of suitably positioned permanent magnets (Fig. 16, not shown), or it can be arranged that the rotor always returns to its " zero " position when the control signals are removed by means of a magnet 18, Fig. 2. To prevent " sticking " the rotor can be bent.

Title: Vacuum type circuit interrupter
IPC: H01H1/02

Abstract: 1,255,685. Vacuum switch contacts. HITACHI Ltd. 25 Aug., 1969 [26 Aug., 1968], No. 42228/69. Heading H1N. [Also in Division C7] The arc supporting regions of vacuum switch contacts 12, 14 are formed of an alloy of a composition such that a thin brittle film 74 is formed on the surfaces to reduce the effects of contact welding; the alloy consists of more than 40% by weight of copper, up to 60% of iron, cobalt, nickel or chromium (or a mixture thereof) and between 0À035 and 7% of lead; the proportion of iron-group metal is to be much greater than its solubility limit in copper so that the alloy has a composite structure of a copper rich phase 70 of high electrical and thermal conductivity and an iron-group rich phase 68 giving the contacts high dielectric strength and the proportion of the lead is also greater than its solubility limit in copper so that it precipitates at 76 on the grain boundaries of the alloy and is readily exuded from the contact under arcing conditions to form the brittle film 74 on the surfaces. The film is sufficiently thin that it does not cover portions of iron-group metals 72 projecting from the contact surface and therefore does not reduce the electrical strength of the contacts. The Specification discusses in detail a large number of more specific alloys within the above set limits. The switch described has two cylindrical body portions 16, 16<SP>1</SP> of borosilicate glass joined by seals 17, 17<SP>1</SP> of iron-nickel-cobalt alloy of equal expansion to the glass; shields 18, 18<SP>1</SP> inside the envelope and 19, 20 attached to the electrodes 10, 13; getters 38, 38<SP>1</SP> and a sheet steel bellows 22.
