Inventor: HEYL GEORGE EDWARD
IPC: C21B13/12
Filed: 1916-04-07
Abstract: 104,064. Heyl, G. E. April 7, 1916. Electrode furnaces.-A process for the reduction of ores consists in crushing the ores with the necessary fluxes and reducing-agents, and feeding the mixture in the form of a thin rod or ribbon by an extrusion apparatus into a region of reducing temperature maintained in an enclosed chamber. The ribbon of ore mixture may be a flat band, or may be tubular, grooved, or fluted, to provide a large surface in proportion to its mass. In the form of apparatus shown, the chamber a is heated by one or more arcs f, h, i, and the ribbon of ore mixture is fed by an extrusion apparatus c, having a narrow slot nozzle e, into a channel b of quick-lime. The metal and slag run off into a crucible g. Hvdrogen or other reducing-gas may be admitted by a pipe j, and the pipe k may serve as a vent or for maintaining a partial vacuum to draw off the fumes. Instead of employing arcs, the furnace may be heated by inductance or resistance.

Title: Electric communication cable
IPC: H01B11/00
Filed: 1928-02-20
Abstract: 312,119. Standard Telephones & Cables, Ltd., and Kaempf, E. Feb. 20, 1928. Cables with artificially modified capacity.-In order to balance capacity differences in a communication cable between pair units which are insulated from each other by paper tape insulation in the form of a single strip, the characteristics of the insulation are varied by varying the quality or composition of the paper, by varying its volume without varying the width or thickness of the tape, or by using string spacers between the insulation and the units. In a cable containing star quads, capacity compensation is obtained by varying the diameter, volume, specific weight, composition, form, or number, of strings placed in the centre of the star quads. The methods may be used also to balance capacities due to unequal phantom twists.

Title: Construction of aircraft runways, roads, floors, and like surfaces, and manufacture of water-repellent materials therefor
IPC: E01C7/36
Filed: 1943-04-02
Abstract: Aircraft runways, floors, roads and like surfaces are prepared by applying to the ground, or to laid surfaces of soil, sand, ashes, ground cinders, stone dust, or the like, an aqueous solution of the ammonium or other water-soluble salt of a water-insoluble carboxylic acid, and an aqueous solution of a multivalent metal salt, to form a water-repellent, water-insoluble salt; alternatively, soil &c. can be mixed with the ingredients and, if desired, with binders such as asphalt, bitumen, or anhydrous calcium sulphate, and compressed into blocks to be laid as required.  When treating the ground direct, the surface may be first harrowed or otherwise loosened, the solutions may be applied by travelling machines and their incorporation facilitated by mechanical means, the surface may subsequently be rolled or otherwise consolidated, and a covering of tar-macadam, cement or other surfacing material may be applied.  Suitable acids are fatty acids such as oleic, stearic and palmitic acids, wood and gum rosin, tall oil, naphthenic acid, or alkyd resins having a sufficiently high acid value to form salts and modified, if desired, with fats, oils, fatty acids, or colophony; the salts may be the sulphates, chlorides, or acetates of aluminium, iron, chromium or calcium.  There may also be added oils such as the glycerides of oleic, stearic and palmitic acid, lubricating oil, paraffin wax, ceresin, carnauba wax, or sterols or sterol esters such as those in wool fat.  According to examples, aluminium sulphate solution is employed in conjunction with (a) the ammonium salt of a product obtained by distilling wool fat and containing some saponifiable and some non-saponifiable material, (b) the sodium salt of crude oleic acid obtained by the hydrolysis of sperm oil and containing wool grease as a liquefying agent, and (c) sodium rosinate containing methanol as a liquefying agent.

Title: Improvements in insulators
IPC: H01B17/32
Filed: 1961-02-14
Abstract: 960,160. Insulators. COMPAGNIE GENERALE D'ELECTRO-CERAMIQUE. Feb. 14, 1961 [Feb. 19, 1960], No. 5433/61. Heading H2C. A line suspension insulator comprises a tension resistant central core provided at each end with an attachment fitting, an insulating protective envelope of ceramic material surrounding the core and a porous ceramic tube disposed between the core and the envelope. The porous tube need not be in one piece but may be constituted from stacked elements. Preferably the porous tube is impregnated with an insulating material, and it may be bonded to the core with a first medium and bonded to the envelope with another. The impregnant may be a synthetic resin, for example a resin of the aminoplast type such as a tricyanamide or cyanuramide resin, or alternatively an alkyd resin. In this case the porous tube may be bonded to the core with an epoxy resin or with sulphur applied in the molten state, and may be bonded to the envelope with an epoxy resin, sulphur, a silicone grease, or an insulating compound. The impregnant may instead be sulphur, and then the bond between core and porous tube is preferably constituted by sulphur. As a variant the porous tube may be bonded to the core, envelope, or to both with an insulating mass obtained by adding mica and a pulverulent filler such as sand or powdered graphite or slate to an initially liquid material such as a heathardenable resin or sulphur, the mica preventing sedimentation of the filler before the mass solidifiers. An example of such a material contains mica, sand, and both an epoxy resin and a synthetic rubber-like material. Before assembly of the insulator the core may be provided with a sprayed-on high reflectance layer of a refractory oxide or mixture of oxides such as Al 2 O 3 , MgO, Zr0 2 , CeO 2 . In the event of destruction of the envelope and subsequent arcing this layer reflects radiant energy and protects the core from overheating. A similar reflecting layer may be provided on the porous ceramic tube.

Title: Improvements relating to welding generators
Inventor: BAYLES JOHN WALLIS
IPC: B23K9/10
Filed: 1953-02-26
Abstract: 735,537. Control systems for welding generators. REYROLLE & CO., Ltd., A. May 25, 1954 [Feb. 26, 1953], No. 5468/53. Addition to 692,155. Class 38 (4). In an automatic idling device for a motordriven welding generator as described in the parent Specification, wherein a solenoid is energized to throttle back the motor if the flow of welding current is interrupted for a predetermined "delay" period, the solenoid is controlled by normally open contacts of a relay which operates to close these contacts when welding ceases and at the beginning of the "delay" period and which maintains them closed so long as idling continues. In the arrangement shown in Fig. 1, the solenoid S is controlled by a primary relay B and a secondary relay A, the last of which is associated with a "delay" period circuit R1, D and all of which are energized from the welding circuit X, Y. Upon cessation of welding, the voltage across X, Y increases to a value which causes relay A to respond, closure of its contacts a2 then energizing relay B, which locks-in over contacts b3, de-energizes relay A by opening contacts b2 and prepares an energizing circuit for the solenoid at contacts b1, which circuit is completed by closure of contacts a1 when relay A drops out after the "delay" period imposed by R1, D. A contact s1 which short-circuits a resistor R3 when the solenoid is energized allows relay B to remain actuated by the voltage obtaining in the welding circuit after the motor has been brought to idling speed-which voltage may be increased by the provision of auxiliary contacts s2, s3 which short circuit resistances in the field circuit of the generator. Relay B drops out when welding is recommenced, due to the very low voltage then across X, Y, solenoid S is consequently de-energized and normal running conditions restored. The solenoid S may be controlled indirectly by contacts al, b1 by a contactor which also operates the contacts s1-s3. In a modified arrangement, Fig. 3, a mechanical delay on the solenoid S replaces the delay relay A.

[Class 4.] A n apparatusfor training aviators or for use as entertainment apparatus comprises a fuselage 1 universally mounted on a support 19 and fitted with fluid pressure means under control of a lever and rudder bar for maintaining the ,fuselage upon an even keel and pointed in the right direction. Means are provided for creating disturbances which the pupil is called upon to correct and the number and directions of the errors are indicated. The fuselage rests with freedom to turn upon a platform 25 mounted by a cardan joint upon the support 19 and the platform is connected by chains 35 to four bellows 32, 33, 36, 37 arranged in pairs to control fore and aft and lateral tilting movements of the platform. Horizontal rotary movements are controlled by two other bellows 39, 40 mounted on the seat back and connected by cables passed over pulleys on the fuselage to points on the platform. The bellows are connected in pairs by pipes 50, 51, Fig. 9, to three rotary valves 48 comprising fixed and movable plates 48, 55, two of which plates 55 are moved by links 70, 74 connected as shown to a universally mounted lever 65, and the 'third plate by a link 77 connected to a rudder bar 76. The lever 65 and rudder bar 76 also move dummy elevators 7, ailerons 5 and rudder 6, Fig. 1. The pipes 50, 51 are led to ports 53, 54, Fig. 11, in the fixed plate 48 of each valve and the movable plate 55 has four ports 57 .. 60 shaped as shown. The ports 57, 59 communicate by passages 61, 62 with a central pipe 49 kept exhausted by a pump 47, Fig. 9, driven by an electromotor 46. The other two ports communicate with the atmosphere through holes 63, 64. When the valve is in a central position both ports 53, 54 are open to the source of reduced pressure and the corresponding bellows are equally contracted to centre the device. A sighting device is provided comprising a lamp 113, Fig. 1, on the fuselage and a ring 112 carried by the fixed part of the apparatus. Electric switches controlled by movements of the fuselage complete a circuit to light up the lamp whenever the line of sight deviates beyond the ring 112 and simultaneously a solenoid is energized to move the ratchet of a counter on the dashboard to indicate the number of such deviations. When the apparatus has been centred a switch 108 on the dashboard may be closed to start a motor 97, Fig. 9, for slowly driving a disc 99 adapted successively to put a series of ports 94, connected by pipes 95 to the pipes 50, 51, into communication with the atmosphere through a pipe 103 in order to create disturbances in the balance of the device. The end of the pipe 103 is normally closed by a plug 105 which is withdrawn by an electromagnet 107 when the switch 108 is closed. The motor 46 may be started by a switch 134 or a coin freed apparatus 135 in the cockpit.
