Patent RU-94015179-A (RU)
Inventor: FLOJD IZBREHND
IPC: H01B13/00
Filed: 1994-05-04
Abstract: FIELD: electric engineering. SUBSTANCE: cast cable includes several wires and plastic material interleaved with wires into fabric-like structure for protection of wires and their containment at some distance from each other. Fabric-like structure of plastic material is usually formed by casting under pressure. Cable includes wires which are kept from first to last one at some distance relative to each other and have initial and terminal bases. Narrow belt of plastic material forms initial base around wires, then it passes above first wire, under second wire, above third wire and continues such fabric-like structure till last wire is included into it. Then belt braids last wire and interleaves wire in backward order to first wire braiding them together and keeping them at some distance from each other. Such fabric-like structure is repeated to terminal position at which terminal base is formed around wires. EFFECT: high quality of manufacture of cast cables.

Abstract: FIELD: radio engineering. SUBSTANCE: invention can find use in radio systems of various assignment. Directional antenna has metal zigzag-shaped radiating cloth arranged into ring filled by two metal sectors having angle β close to feed terminals and flat screen-reflector. Metal sector of radiating cloth have cuts in the form of parts of segments formed by arcs of radius R=0,18 λand chords passing at distance l=0,15 λmax from feed points. Side surfaces of zigzag-shaped radiator are interclosed in diametrically opposite sectors by resistor R = (100-200) Ohm in points located at distance l=0,15 λmax from feed points of zigzag-shaped radiator. Novelty lies in making of cuts in the form of segments formed by arcs of radius R=0,18 λmax and chords passing at distance l=0,15 λmax from feed points in metal sectors of radiating cloth. Use of proposed approach makes it possible to reduce twice dimensions of antenna and to expand its operational range to proportion 2.8:1. EFFECT: reduced dimensional characteristics of antenna, expanded operational range of antenna without any change of its basic electrical characteristics.

Title: Method and device for controlling solidification of molten alloy in induction furnace with water-cooled copper crucible
Inventor: LIAN SHUANG-SHI
IPC: C22C1/02
Filed: 2002-12-02
Abstract: A method for controlling the solidification of a molten alloy in an induction furnace with a water-cooled copper crucible uses a water-cooled copper crucible vacuum induction furnace process to smelter a metal, particularly an active metal, while obtaining an ignot with oriented solidification texture. A water-cooled copper crucible vacuum induction furnace is a type of vacuum induction furnace with cold crucible and a technique for smelting metal and obtaining a steel with a high purity which is currently being developed by the advanced industrial countries. Such a technique has the merits of fast smelting rate, and uniform components and temperatures. However, such a technique has a big disadvantage due to the cooling water used by the water-cooled copper crucible entrains a large quantity of heat, thereby causing an excessively low efficiency in smelting metal. The present invention uses a water-cooled copper crucible as a solidification mold and as means of controlling the solidification texture of the alloy fluid by controlling the operation parameters of the induction furnace and altering the design of the copper crucible in order to obtain an ingot which is clean, free-of-impurities, and oriented or has fine grains.
