Title: Distance relay for electrical supply networks
IPC: H02H7/30
Filed: 1932-08-23
Abstract: 393,442. Protective cut-out arrangements. ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Aug. 23, 1932, No. 23578. Convention'date, Aug. 24, 1931. [Class 38 (v).] An impedance relay having opposing voltage and current coils of the type in which during operation the effect of the current-coil is increased in steps by the action of a time - element relay, has the current-responsive element formed as an induction relay with an auxiliary phase or pole - shading winding connected to a resistance which is gradually diminished by the time-element relay until the shading coil is finally shortcircuited. As shown in the Figure the relay has a voltage element consisting of a solenoid 5 fed through the potential transformer 6, the solenoid core 4 being carried at one end of a pivoted arm 1. The other end of the arm 1 carries a vane 7 inductively operated by an electromagnet 8 carrying a current coil 9 fed by a series transformer 16 and provided with an auxiliary phase or pole-shading winding 10 connected to a resistance 11 which is under the control of a time-element relay 14. The latter is brought into action by an overload relay 15 and by means of a regulating switch 12, 13 gradually cuts out resistance sections until the action of the current element of the impedance relay becomes predominating and the arm 1 is moved against the spring 18 to bridge tripping contacts at 17, the time of operation being a measure of the impedance of the controlled line and the distance to the fault. A variable bias may be introduced into the operation of the impedance relay whereby it may be applicable to feeders of different lengths by the provision of a second auxiliary phase or pole-shading winding on the current core, Fig. 2 (not shown), this winding being shunted by a resistance the value of which may be altered to vary the amount of bias exerted. Alternatively the solenoid 5 may be connected to different steps on the transformer 6 or the value of the resistance 11 may be altered.

Abstract: 456,233. Oil-well hooks. OIL WELL ENGINEERING CO., Ltd., Cheadle Heath, Stockport.-(National Supply Co. ; Toledo, Ohio, U.S.A.) Aug. 22, 1935, No. 23620. [Class 89 (ii)] In oil-well hooks, in order to facilitate such operations as the change from drilling to the operation of removing the drill pipe from the well, the hook is provided with a device to which the elevator sections may be attached, which device being situated immediately beneath the centre of gravity of the pivoted hook, falls into position when the drill is removed from the hook. As shown in Fig. 6 the bail 51 of the elevator is engaged in recesses 65 in the yoke 5, 6 which swivels on the base of the hook. The hook may be locked in either drill receiving or elevator receiving positions. The hook is spring mounted, the spring 6 surrounding the stem 7 being mounted in the casing 2. The movements of the spring are damped by oil which fills the casing. The damping effect is relatively ineffective on the downward travel of the shank as a check valve 31 controlling the oil passage 30 opens. During the upward travel of the shank the valve closes and the oil flow is confined to the constriction 28 The differential piston 12 has diameters 21and 23 designed so that the oil may be transferred from one side of the piston to the other without undue compression. A device for locking the swivelling hook comprises a lock-shaft 38 mounted in the cap 16 enclosing the oil space and rotatable to bring teeth into engagement with the teeth of a lock ring 33 splined on a nut 13 screwed to the upper end of the stem 7.

Title: Improvements in or relating to detecting, indicating and recording the presence of inflammable vapours or gases
IPC: G01N7/12
Filed: 1925-09-28
Abstract: 267,990. Ringrose, H. T. Sept. 28, 1925. Gas analysis.-Apparatus for detecting, indicating or recording the presence of inflammable gases or vapours, such as marsh gas in mines and oil vapour in ships, comprises a porous vessel which is capable of maintaining a gas pressure for a substantial time and through which the inflammable gases diffuse or into which they are aspirated, a reduced pressure proportional to the amount of inflammable gas present being produced in the porous vessel by combustion of the gas without absorption of carbon dioxide or with vapour &c. and operating an indicator or recorder. An audible or visible signal may be given when the inflammable gas reaches predetermined concentratiuns. The combustion may be produced by platinum wire with or without platinum black or other catalytic material and heated by an electric current. To avoid errors due to the heat of the wire and to atmospheric pressure, temperature and humidity, two porous vessels may be connected to a pressure gauge, combustion in one being prevented by totally enclosing it to prevent its exposure to the gas or by enclosing its heating element in a small bulb plugging into electric terminals or by dimensioning its heating element so that its temperature is below the ignition point of the gases. The water vapour produced in the combustion vessel condenses and may be drawn off by a tap or trap without disturbing the pressure and the space within the other porous vessel or within both vessels may be maintained saturated with water vapour by a wick partly immersed in water. A porous vessel 6 may be held by a clamp 7 with interposed rubber washers 12 against a base 2 and closed by a cap 13 carrying insulated .leads to the heating filament 16, the cap 16 being pressed against a rubber ring 17 by a clamp 19. The vessel 6 is surrounded by a perforated cover 1 and the interior of the vessel 6 is connected by a tube 22 to a monometer connected to a similar vessel which has its filament 16 enclosed in a bulb 23. In modifications, a single porous vessel is employed or two porous vessels separated by a partition are combined into a single unit with the indicator or recorder mounted at one side, the outer ends of the vessels being closed by cover plates carrying the filaments and held together by threaded rods. One of the Provisional Specifications states that the products of combustion may be absorbed.
