Title: Improvements relating to circuit breakers for use in alternating current electric circuits
IPC: H01H9/44
Filed: 1930-01-10
Abstract: 340,797. High - tension switches. ELECTRICAL APPARATUS CO., Ltd., and BARBOUR, R. H., Vauxhall Works, South Lambeth Road, London. Jan. 10, 1930, No. 1037. [Class 38 (v).] Arc-rupturing.-In an A.C. circuit-breaker provided with a grid of vertical 1 plates for deionizing the arc gases, the interruption takes place in a passage within the e series o f plates which are of solid non-perforated construction and spaced apart with free air spaces between them so that the arc cannot leave the passage without being split up. As shown, in connection with an interrupter provided with a magnetic blow-out coil 16 surrounding a core 1 provided with polar projections 2, the superimposed plates 11 are secured to the projections 2 by means of bolts 12, 13 having insulating sleeves. The plates are separated from one another by insulating washers threaded on the bolts so that the insulation and separation of the plates use up a minimum of the interplate space. The lower bolts may be of magnetic material to constitute a continuation of the magnetic circuit from the polar projections to produce a field tending to move the arc upwards. A gap 17 is cut away from the lower part of each plate so as to constitute, in the assembled structure, a tunnel in which the fixed and movable contacts 3, 6 are located. The sides of the plates are left open and not closed in with insulating material. Specification 288,781, [Class 38 (v), Electric switches &c.], is referred to.

Title: Thermal preparation of titanium monoxide
IPC: C01G23/04
Filed: 1952-01-15
Abstract: Titanium monoxide is produced by heating substantially pure titanium carbide in contact with titanium dioxide and/or an oxide of a metal other than radium, of Group II of the Periodic Table, e.g. zinc, magnesium or calcium, the heating step being carried out in the absence of an oxidizing atmosphere, e.g. at 1,300-1,750 DEG  C., whereby carbon monoxide is evolved and the Group II metals are volatilized.  These are collected in finely divided state in a cold trap, and may be melted down in the presence of argon.  The reaction is effected either under a vacuum of 1-10 m.m. of mercury or in the presence of argon, neon or helium.  The starting material is prepared by treating ground titanium carbide with hydrochloric acid to remove any iron present, washing, removing any graphite by alkaline froth-flotation, washing, drying at a temperature not exceeding 80-100 DEG  C., mixing with the oxide, pelleting and drying.  The reaction is suitably performed in fired zirconia or barium zirconate vessels.  The use of crucibles of zircon and of alumina is also referred to.ALSO:Titanium monoxide is produced by heating substantially pure titanium carbide in contact with titanium dioxide and/or an oxide of a metal, other than radium of Group II of the Periodic Table, e.g. zinc, magnesium or calcium, the heating step being carried out in the absence of an oxidizing atmosphere, e.g. at 1300-1750 DEG C., whereby carbon monoxide is evolved and the Group II metals are volatilized.

Abstract: 1412813 Position measurement KUIBYSHEVSKY ZAVOD KOORDINATNORASTOCHNYKH STANKOV 10 Jan 1973 1373/73 Heading G1A A digital measuring device for indicating the position of a slide of a machine tool comprises a first optical system 1-8 for projecting an image of a line indicator 7 fixed to the slide on to the screen 9 of a CRT camera 10, and a second optical system 11-15 for projecting the image of a fixed graticule 13 on to another part of the screen 9, the camera 10 being controlled by an external synchronizing trigger 20 and operated by the usual X-deflection saw-tooth waveform generated at 16, 18, and having a Y-deflection system 19 comprising a trigger 21 and push-pull amplifier 22 which when enabled causes a vertical shift in the electron trace. In operation, the electron scan commences in the X-direction until the presence of the image of mark 7 is detected, a pulse produced thereby being taken via amplifier 24 through gate 25 to two shapers 26, 27. The output from the shaper 27 is not conducted further since AND gate 34 is not enabled, but the pulse from shaper 26 passes via trigger 28, delay stage 29 and trigger 30 to open open an AND gate 32 to allow a first counter 33 to count pulses from a generator 31. AND gate 34 is opened by the delayed pulse from device 29 and passes the first pulse indicative of a graticule ruling to arrive after the enabling pulse, and all such pulses thereafter, to a second counter 35. The first pulse of this track causes gate 32 to be closed to stop the track of generator pulses to the first counter 33. The slope of the saw-tooth X-deflection voltage may be non-linear to compensate for errors caused by distortion in the optical systems. Circuitry of all the elements is given.

Abstract: 416,248. Vibratory massage. BINNEY, E. A., Shirley, Rupert Road, Ilkley, Yorkshire. Jan. 18, 1934, No. 1754. [Class 81 (ii).] A device for vibratory massage treatment is made in the form of a relatively-thin, flexible pad which is adapted to conform to the shape of the part of the body to be treated, the vibrations being produced by means of an electromagnet which is connected to an alternating current supply. The device comprises an armature 1 and a polepiece 2 consisting of thin steel plates slotted transversely and clamped together at their edges by a flexible clamping member 4, preferably formed of rubber. The central portion of the plate 2 is bent to form an upwardly-extending offset portion 2d which approaches closely to the plate 1. A coil 3, preferably wound with thin or stranded wire, is enclosed in the channels formed between the sides of the plates 1, 2, and the whole is enclosed in a suitable flexible insulating covering or bag 5. In use, the coil 3 is connected to an alternating current supply, and the pulsating magnetic flux causes vibration of the plates 1, 2, which is imparted to the part of the body to which the pad is applied. The thinness of the plates 1, 2, and the use of the transverse slots 2<a>, enables the pad to be bent to conform to the body. The heating of the coil and the plates 1, 2 serves to warm the pad. The space between the pole portion 2d and the cover 5 can be filled by means of a pad 8 of flexible material such as rubber.
