IPC: H05H1/48
Filed: 1963-08-07
Abstract: <PICT:1043384/C1/1> In an arc furnace for heating solid material, comprising a sealed gas-filled chamber 1, the diameter of the arc between adjustable electrodes 20, 21 is varied by rotating at various speeds an open-ended tube 6 fitted with internal vanes (not shown) so that the gas surrounding the arc is rotated at any desired angular velocity without appreciable axial flow.  The solid material is fed to the arc through a tube 43 and the electrode 20 and, after falling through the arc, is cooled (if desired) and collected by members 30-33.  Arc-operating data is given for the production, in an atmosphere of nitrogen, of 150 micron diameter spheroids of zirconium diboride of melting-point 3750 DEG  K.

Abstract: 384,766. Fusible cut-outs. ROSS, F. A., 23, The Broadway, Tynemouth, North Shields. Nov. 11, 1931, No. 31217. [Class 38 (i).] A fusible element melting at a low temperature comprises a fusible metal and a spring embedded therein or conjoined in parallel, the spring being normally under tension or compression, and contracting or expanding upon fusion of the element, to open the circuit. The spring a, Fig. 3, is under tension and embedded in the fusible metal b, the spring being cut through at the centre and secured to end tails c by rivets e, e<1>, small discs d being inserted between the coils of the spring before the metal is run in. The end tails c are reduced in section by a number of holes, or by tongues g which may be used for attaching high temperature melting nickel wires h in parallel with the fusible element. These nickel wires h are embedded in arc-damping powder contained in a refractory tube to and, taking the current upon fusion of the low temperature metal, prevent the establishment of an arc across the spring elements. In a modification (not shown) silver wires are connected in series with the low temperature fusible element and the whole enclosed in arc-damping powder and a container provided with cavities into which the metal is precipitated upon fusion. In Fig. 5, a tapered spiral spring a is held in compression by the metal b and silver wires r are attached to the metal through the end sealing discs s and enclosed in arc-damping powder. Metal contact end tubes m are screwed into the' outer container o and into these tubes are projected the springs a upon fusion of the metal band severing of the contact with the silver wires &c. Specification 228,949, [Class 38 (i), Electric couplings &c.], is referred to in the Provisional Specification.

Abstract: 465,744. Paper for writing upon with hard substances. EVANS, D. Nov. 13, 1935, No. 31431. Drawings to Specification. [Classes 96 and 140] [Also in Group XV] A writing or drawing surface consists of a sheet or web of paper or thin fabric impregnated wholly or in part with wax such as paraffin wax or beeswax and having before impregnation a white or light coloured obverse side on which the writing is directly or indirectly effected, the reverse side forming a black or dark coloured background for the obverse side. Writing may be effected by the blunt end of a needle, pin, or other smooth non-cutting pointed object, and the writing may be obliterated by the application of heat. The sheet or web may be for use in a typewriter or the like, thus obviating the use of ink ribbons, or envelopes may be wholly or in part made from such a sheet, the waxed surface being on the outside, or one or more such sheets may be associated with suitable backings and covers to form either a booklet or a pad. The sheet may be of opaque or translucent paper, or thin fabric such as silk or satin, the obverse side being waxed, and the reverse side being coated, printed, or otherwise treated with ink or a coloured dye to provide the background. The obverse side is white or light coloured before waxing, and after waxing the dark background shows through the paper or fabric. In a modification, the dark background may be provided by folding an integral and dark coloured sheet beneath the waxed sheet. The waxed sheet may be superposed on and attached all over to a backing which is dark coloured if the reverse side of the waxed sheet is not dark coloured.. Specification 28733 /09, [Class 146 (ii)], is referred to.

Title: Improvements in or relating to electrolytes for solid electrolyte devices
IPC: H01M6/18
Filed: 1960-09-13
Abstract: A solid barrier silver halide electrolyte material, e.g. the chloride, is characterised in that there is incorporated in the material at least 0,1 moles per cent of divalent sulphur, selenium or tellurium anions, preferably between 0,1 and 6 moles per cent, for example in the form of compounds with silver.

Abstract: 1,019,413. Photo-electric monitoring for flashover. SIEMENS & HALSKE A. G. Aug. 13, 1963 [Aug. 16, 1962], No. 31898/63. Heading G1A. To protect high-frequency transmitting apparatus against damage due to arcing or flashover at least one photo-electric detector is arranged to optically monitor a component subject to arcing or flashover and to provide an output signal when a discharge occurs. The signal is applied to switching means to reduce the voltage applied to the component to extinguish the arc. The arrangement may incorporate alarm signal devices. In a preferred embodiment housings each containing a unit of a radio or television transmitter are each monitored by the insertion of a photo-electric cell. The leads from the cells pass through respective high-frequency by-pass capacitors and rectifying diodes to a common amplifier. The amplifier output controls a relay with one set of contacts in circuit with an alarm bell or light and another set arranged to interrupt the high voltage power supply to the portion of the transmitter being monitored. The relay is preferably slugged to allow adequate time to elapse between the cessation of discharge and the re-application of supply power. The cells, which may be cold-cathode vacuum tubes or photo-transistors, may each feed an individual amplifier and relay.

Filed: 1925-12-17
Abstract: 244,794. British Thomson-Houston Co., Ltd., (Assignees of Hutt, L. P.). Dec. 19, 1924, [Convention date]. Interrupter and intermittent resistance controllers.-For giving a wide range of speed variation, as in motors for training and elevating search-lights, an interrupter controller is associated with a reversing switch in the motor armature circuit, the field remaining continuously energized during speed variation and reversal. The interrupter controller comprises a contact 3 mechanically reciprocated by an auxiliary motor C so as to meet a resiliently mounted contact 4 and thereby complete a circuit through the armature of the controlled motor A for recurring periods of variable duration. A similar resiliently mounted contact 8 is disposed on the other side of the contact 3 and is brought into use when reverse rotation is required. The apparatus may, as shown, be duplicated in order to control two motors A, B for training and elevating. The lower half of the interrupter comprises a contact 9 mounted on the same reciprocating member as 3 and co-operating with one or the other of contacts 10, 14. The periods of the current impulses are varied by a hand lever 35, Fig. 5 which displaces a member 31 carrying contact stops 32, 33 disposed to bear against the resilient mountings of the contacts 4, 8, in the manner shown in Fig. 4. A second lever, geared to move in a plane perpendicular to the first, varies the position of contacts 10, 14 in a similar manner. The levers serve the further purpose of changing over reversing contacts 6 and 7, or 12 and 13.
