Title: Improvements in the system of signalling and remote control by means of high frequency currents superimposed on distribution networks of electrical energy
IPC: H02J13/00
Filed: 1934-06-18
Abstract: 444,556. Signalling over power circuits. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D' USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. June 18, 1934, No. 18032. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 24, 1934]. [Class 40 (iv)] The Specification, which does not admit of satisfactory abridgment, relates to the propagation of signalling currents of musical or high frequencies over power circuits. This is facilitated by the provision of " damping circuits " which are normally tuned to the frequency of a harmonic that it is desired to eliminate but, on the arrival of a signalling current, are automatically, with the aid of relays, brought into resonance with that current. Alternatively the adjustment may be brought about manually or by clock-controlled contacts.

Drawings to Specification. [Class 83 (iv)] A weld rod for depositing on the surface of a metal part a hard layer of microscopic grains of refractory carbides embedded in a binding metal or alloy fusible at welding temperature, is formed of a mixture of an oxidized compound of a metal yielding hard carbides, a substance basically composed of a metal capable of giving rise to the binding metal and pulverulent carbon, the whole being united by an organic or mineral agglomerating agent. The oxidized compound may be a natural ore or commercial oxidized compound of tungsten, which may be partly or wholly replaced by a similar compound of molybdenum, tantalum, titanium, vanadium, niobium, hafnium, or zirconium, and the binding metal which may be iron or iron alloy may be in the metallic form or in the form of an oxide and used together with a reducing agent such as aluminium. For comparatively low hardness purposes, a tungsten ore such as wolframite containing in addition to tungsten proportions of iron and magnesium oxides, may be mixed with the carbon, but for very hard layers commercial tungstic acid may be mixed with 5 per cent of the coating metal. The agglomerant may consist of varnish sold under the Registered Trade Mark "Bakelite." The mixture may be moulded, compressed or extruded to rod form, may be compressed into a tube of binding metal or applied as a coating to a wire. In one form, the rod may consist of a mixture of 75 per cent of tungstic acid, 18 per cent of pulverized graphite, 6 per cent of carburized ferro-manganese (containing 6 per cent of carbon and 70 per cent of manganese) and 1 per cent of aluminium filings, with 5 per cent of a binder of Bakelite varnish. The articles to be coated may consist of rolling mill guides, aircraft tail skids, dies and punches for stamping and cutting-out machines, valves and valve seats, shear blades, gauges, drawing plates, extruding dies and nozzles, mine appliances, and boring and sinking appliances. U.S.A. Specifications 1,631,942 and 1,824,166, and French Specification 799,040 are referred to.

Abstract: 403,438. Glass manufacture. MOSMIERI, L., 50, Via di Montughi, Florence, Italy. June 28, 1933, No. 18451. Convention date, June 28, 1932. [Class 56.] A process for tempering plates or sheets of glass or other material consists in allowing the sheets, after being sufficiently heated, to cool in the air, and in providing means for drawing away air which has become heated by contact with the hot sheet. The sheet a to be tempered is suspended from a carriage b running on an overhead track and is brought into position between two aspirators g, h. Each aspirator consists of tubes provided with open mouths or slots i and connected to a suction device k. The air heated by contact with the hot sheet is sucked away continuously through the mouths i so that the plate is always in contact with cold air. In order to render the cooling action more uniform, the aspirators may be mounted on a carriage which is reciprocated by a crank. The plate a may also be moved during the tempering operation.

A fluid-pressure operated fluid-flow or electric current flow control device comprises a rigid container having a first partition 8 and a second partition 9 to provide three chambers, part at least of each partition being movable under the influence of fluid-pressure, an orifice 14, 15 leading from the intermediate chamber which is closed by the partition 8 when it moves in the direction to reduce the volume of the intermediate chamber, fluid-pressure operated means 22 associated with the partition 8, a passageway 64 connected to a source of constant bias pressure, a passageway 65 connected to a source of servofluid, a passageway 67 connected to a source of fluid at adjustable pressure, and an electric current or fluid-flow control means 50 associated with the partition 9 to control the flow in accordance with the fluid-pressure differential applied to the means 22. In the preferred embodiment, the means 50 consists of a valve which controls the supply to a hydraulically-actuated outlet valve from a water filtration bed, the rate of flow in the outlet being converted by a Venturi to a pressure differential applied to the means 22. The pressure differential determines the position of a valve 13 in relation to the orifice 14, 15 and hence the pressure in the chamber 6 through which the servofluid flows through the orifice to atmosphere. Deviations in this pressure from a value equal to that supplied to the passageway 67 displace the valve 50 from its central position where it is normally retained by springs 51, 52. A pressure gauge calibrated in gallons per minute may be connected to the chamber 6. The rate of change of position of the valve 50 may be adjusted by a needle valve 47. An alternative embodiment has the diaphragm 9 arranged to close a pair of switch contacts to operate an alarm and may be used in conjunction with the embodiment of Fig. 1'. A spring may be used, instead of fluid-pressure, to bias the diaphragm 8.
