A metal housing 10 is divided into two chambers by a rigid metal insert 30 having a central aperture for a pin 40, the head of which abuts a diaphragm 20, for example of rubber, in the lower chamber which has an inlet 13 for fluid under pressure; the diaphragm 20 has a self-sealing projecting edge 21. The other end of the pin 40 contacts an insulating plate 50 in the upper chamber which also contains an insulating core 70 carrying terminals 80 and 90, the end 81 of terminal 80 being lower than end 91 of terminal 90. The plate 50 carries a contact-spring 60 against which bears a spring 100 whose pressure is adjustable by a set-screw 110. The core 70 has a metallic casing 120 to ensure mechanical strength and dimensional stability and the edge 14 of the housing 10 is tightly flared over the margin of easing 120. On the application of pressure in the lower chamber the diaphragm 20 (via pin 40) causes the spring 60 to first engage contact point 81, then the point 91, and then to flex slightly at the centre; the final pressure on contacts 81 and 91 being determined by the abutment of the head of pin 40 against the insert 30.

Title: Improvements in and relating to isolator switches provided with earthing devices
Inventor: BOERSMA RINTJE
IPC: H02B11/28
Filed: 1970-01-26
Abstract: 1,256,054. Metal clad switchgear. COQ N.V. 26 Jan., 1970 [4 Aug., 1969], No. 3665/70. Heading H1N. [Also in Division H2] In a high voltage, double break, metal clad isolating switch of the kind having two gas tight compartments separated by an insulator 3 which supports two movable contacts whereby each compartment contains a fixed and a movable contact and means are provided to connect the movable contacts to the metal casing in the open position, the two portions 1, 2 of the casing which surround the two compartments are insulated from one another and connect to earth by individual conductors 21, 22 and means is associated with the two conductors for indicating in which chamber an earth fault, if any, exists. In Fig. 1 (not shown), where the isolating and earthing contacts are arranged as disclosed in Specification 1,254,790, the two movable contacts are insulated from one another but connected by an auxiliary switch in all but the fully open position of the contacts; two indicating devices respond independently to fault currents in the two conductors. In Fig. 2 the two movable contacts 30, 31 are permanently connected; a current transformer 36 responds to the current in the connection 32. Two further current transformers 23, 24 respond to the current in the two conductors 21, 22. A single earthing contact 35 is provided. While the contacts 30, 31 are closed a current in connection 32 energizes equally windings 40, 42 of two transformers 37, 38; the secondary windings 43, 44 are also equally energized and a balanced relay 45 remains unoperated. With the contacts 30, 31 open and earthed, if an earth fault occurs between fixed contact 33 and envelope portion 2, fault current flows only in conductor 22 and therefore only winding 47 of relay 45 is energized to operate a first indicating device 51. Similarly an earth fault between fixed contact 34 and envelope portion 1 energizes only winding 46 and a second indicating device 49. If a fault occurs between contacts 31, 34, three windings 40, 41, 42 of the transformers are energized, only secondary 43 giving any output whereby indicator is again operated to indicate a fault in the right hand compartment. In a modification (Fig. 3, not shown) the three current transformers 23, 24, 36 energize respective relays 52, 54, 53 whose several contacts are interconnected to operate the appropriate one of indicators 49, 51.

Abstract: 1,155,941. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan. 25, 1966 [Jan.28, 1966], No.3880/66. Heading G3R. A battery charging system for a road vehicle comprises terminals 33, 34 for connection to a battery 32; a generator 31 for charging the battery; and a voltage regulator 37 for the generator, at least the voltage sensing part of the regulator being connected to the contact 39 of a relay 42 responsive to the generator output and also, over a diode 38 and the ignition switch 36, to the terminal 33, the other side of the regulator being connected to the terminal 34. The arrangement is such that with the switch 36 closed and the generator producing no output, current flows through the diode 38 and contact 39 to illuminate a warning lamp 41 and at the same time current flows to the regulator 37 so that the field winding of the generator is energized; with the generator now operative relay 42 is energized and contact 39 moves to its alternative position so that the lamp 41 is extinguished and the series circuit of the switch 36 and diode 38 is short circuited, the voltage sensing part of the regulator then being connected directly across the battery terminals. The diode 38 protects the regulator against any reversal in voltage across the ignition circuit. The regulator may be of the transistor type or of the electromechanical type, and the generator may be an alternator with a rectified output. A transistor (43) may replace the relay (42, 39 Fig. 3, not shown) and the diode 38 may be constituted by the base emitter circuit of a further transistor Fig. 4 (not shown).

Title: A process and apparatus for the degasification of coal dust
Inventor: WOLF OTTO
IPC: C10B49/08
Filed: 1957-02-05
Abstract: 858,362. Coking. STEINMULLER G.m.b.H., L. & C. Feb. 5, 1957, No. 3945/57. Class 55 (1). Coal gas and finely divided coke are produced by grinding coal to dust, superficially oxidizing the particles by blowing them through a nozzle 11 into a primary tubular chamber 1 with a gaseous carrier so as to render the coal particles non-agglutinating, the oxidation being brought about by a partial combustion of the gaseous carrier, and carbonizing the coal particles in suspension. The gaseous carrier in chamber 1 may be flue gas, coal gas, generator gas, recycle gas from the carbonizing chamber or the hydrogen content thereof, and the partial combustion, which may be effected mainly with the hydrogen content of the carrier gas, may employ oxygen-enriched air or oxygen. The partial combustion may be promoted by adding ether, benzine or acetylene. The coal dust fed through nozzle 11 may be introduced into the chamber 1 with the aid of part of the gaseous carrier or with water vapour. The combustion chambers 12, 13, 14 are connected at one end to feeder 15 for the remainder of the gaseous carrier and at the other end to feeder 16 for air or oxygen, the chambers 12, 13, 14 discharging tangentially into the chamber 1 and also into a cavity 17 between the double walls of the chamber 1. Alternatively sodium circulation may be used to heat the chamber 1. The gaseous mixture from chamber 1 passes through lines 18, 31 to a heat exchanger 32 where the gas is cooled sufficiently for the water vapour to be condensed, and the coal particles, which are separated in cyclone 3, pass through preheater 4 and are mixed with a carrier gas which has been heated at 5. The coal particles are degasified in shaft 2 which is heated by passing part of the preheated carrier gas through pipe 21 into the space 22 between the double walls of shaft 2, or alternatively heated by flue gas or by sodium circulation. Specification 857,919 is referred to.

Filed: 1925-02-12
Abstract: 229,654. Westinghouse Electric & Manufacturing Co., (Assignees of Pearcy, N. C.). Feb. 20, 1924, [Convention date]. Vacuum tubes; low - pressure metallic-vapour apparatus.-A thermionic electrode comprises a heating element, an insulating refractory member surrounding the heating element or in which the element is embedded, and a sleeve consisting of sintered particles of nickel or other metal, and of one or more oxides of the alkaline earth metals. As shown, the electrode consists of a sleeve 12 surrounding a member 8 of zircon or porcelain, in which a heating element 9 is mounted. The electrode is prepared by dissolving nitrates of the alkaline earth metals in water or other solvent, and precipitating insoluble salts, for instance carbonates, by adding ammonium carbonate; proportions of the nitrates are given. Finely-divided nickel, obtained by heating nickel oxide in hydrogen at 600‹ C., is mixed with the carbonates, and a binder such as acetic acid is added, which reacts with a part of the carbonates to form a soluble salt. The resulting plastic mass is extruded through a die as a rod, slab, or sleeve, which is dried, and then sintered by heating in hydrogen at 1000‹ C. The carbonates may be reduced to oxides either during the sintering process, or after the electrode has been mounted in the bulb. In a modified process the plastic mass is formed into a sleeve surrounding the heated member 8, and the composite body is heated in a furnace for carrying out the sintering process. In another process the refractory body is coated with nickel or other metal, and is heated when the electron-emitting sleeve is applied, so that the nickel coating is plastic and forms an intimate connection between the body and sleeve. The circuit of the heating element may be opened after starting, and the supply of electrons maintained by bombardment by positive ions. A contact strip 6 is secured to the sleeve by wire 13. The bulb may contain argon or mercury vapour. In; a valve for double-wave rectification two anodes are connected with one secondary of a transformer, and the heating element of the cathode is connected with another secondary.

Abstract: 1,011,164. Endless conveyers. IZUMI CHEN KABUSHIKI KAISHA. Nov. 14, 1961, No. 40765/61. Heading B8A. Trolleys 22 (Fig. 4) are detachably carried on chains 13 of an endless conveyer (Figs. 1, 2) by the engagement of lugs 48 on the trolleys with corresponding sockets 20 on links 18 carried by the chains. The trolleys 22 are attached to, or detached from, the conveyer by means of platforms 21, 21, which are carried by a parallel linkage. A crank 33 of the latter is, by energization of a solenoid 44, brought into engagement with a projection 36 on a link 35 which is continuously reciprocated by an eccentric 40 and link 39. Thus, when the solenoid 44 is energized, the platforms are oscillated with a combined vertical and lateral movement so as to carry a trolley 22 into engagement with the conveyer, or alternatively to detach a trolley from the conveyer. This action is facilitated by the endless member being trained at the feed/discharge stations by pulleys 16, 16, into sloping paths 17 (Fig. 1).
