Title: Improvements in or relating to devices for controlling electric current circuits
IPC: H01H87/00
Filed: 1947-02-07
Abstract: 621,001. Mercury and other conducting- liquid switches. FKG F. KESSELRING GERATEBAU AKT.-GES. Feb. 7, 1947, No. 3748. Convention date, Feb. 19, 1946. [Class 38(v)] A switch comprises two chambers containing a conducting medium 8 and separated by a partition having at least one current path, so that predetermined currents can flow continuously between the chambers, without variation, but an over-load produces a reduction in or interruption of, the passage of current, due to greater current concentration at one point of the path. The conducting medium may be mercury, or fused salts, or, with A.C., sulphuric acid or soda lye. The partition may be of insulating or conducting material, such as aluminium or carbon, and may be partly hygroscopic, being moistened by wick action with, e.g., water. The insulating partition may (a) be formed with holes filled with the same or a different conducting medium, or (b) contain pins, grains, and the like, which are flush with or project from one or both sides of the partition. The conducting partition 11 may (a) be covered with, e.g., enamel 12, Fig. 5, scratches in the enamel being made to expose the partition in places, or (b) contain pins 5 of good or bad conductivity, Fig. 2. The current may be reduced or interrupted by several means, viz. (a) gases or vapours from the conducting medium, pins or partition &c. due to heating, (b) liberation of gases dissolved in the medium, (c) evaporation of the liquid absorbed in a hygroscopic partition, or (d) the formation of non-conductive coatings, e.g., aluminium oxide, on a conducting partition. The partition may be formed as a double wall, Fig. 6, the intermediate space 15 serving as a buffer to take up pressure impulses and the partitions may be shunted by resistors and condensers 14. The Specification as open to inspection under Sect. 91 states that the conducting medium may be fine powder, e.g., metal or carbon. This subject-matter does not appear in the Specification as accepted.

Abstract: 414,677. Walls ; doors ; partitions for ships. BROWN, D., 29, King Edward's Road, Heaton, Newcastle-on-Tyne. Feb. 4, 1933, No. 3486. [Classes 20 (i), 20 (iii), and 20 (iv).] Walls, doors, and partitions for buildings, applicable also in ships, are constructed of standardized sheet-metal elements assembled to form abutting cavity panels each comprising a pair of flanged face members a, a<1> spaced and maintained in parallel relationship by interposed perpendicular interlocking members d which carry C-shaped strips f, f<1> engaging with, and throughout the length of, inturned lips c, c<1> on abutting flanges b, b<1> of the face members. The interlocking connections lie wholly within the panels. Insulating material may be inserted between each C-shaped strip and the lip it engages. The panels are received at the base in sheet-metal channels g, Fig. 5, supported by a concrete foundation h, and a filling j of bitumen &c. is applied. The channels g are secured by wedges k<1> to flanged U-shaped members k anchored in the foundation, and transverse pins k<2> are passed through the panels a, a<1> and the flanges of the channels g. The tops of the panels are closed by channel-shaped plates m which are secured to the face plates a, a<1> by transverse pins m<4> and are adapted to enclose a layer m<1> of bitumen &c. supported by plates m<2> resting on projections m<3> on the face plates. The cavity panels may be stiffened by transverse members comprising horizontally corrugated or bulged plates n, Fig. 1, spotwelded to vertical V-shaped upright sections n<1>. At vertical corners, the inner face plate a may be bent to a right-angle, as shown in Fig. 1, and the outer face plates may be provided with lipped edges which are connected by a C-shaped strip f, a diagonal stiffener being also provided if desired. The internal partitions may be similarly formed and connected to the main panels as shown in Fig. 6. A filling of concrete, cork dust, peat moss &c. may be provided in the cavity panels. A beaded picture rail y, Fig. 5, is provided with rearwardly-projecting hooks y<1> adapted to engage behind projections y<2>formed on the face plates a<1>. A metal skirting board may be similarly formed. Door and window frames are formed of channel section and are recessed as shown at r<1>, Fig. 2, to accommodate the door or window.

Title: Improvements in hydraulic shock dampers
IPC: F16F9/26
Filed: 1934-02-02
Abstract: 432,725. Fluid - actuated valves. BELL, W., Rose Lea, Osmaston Park Road, Derby. Feb. 2, 1934, No. 3486. [Class 135] [See also Group XXXII] A valve which opens in the same direction to allow passage of liquid when flowing in either direction through a conduit connecting the two compression chambers of a hydraulic shock-absorber carries a slidable sleeve which bears on the valve when urged in a direction to open it but which does not influence the valve when urged in the opposite direction. As shown, the shock-absorber comprises a double-ended piston a formed in two parts spring-pressed against the lower end of an operating lever b which acts on case-hardened members b<1> to reciprocate the piston in a cylinder a<1>. The compression chambers are connected by a conduit d, d<1>, d<2>, d<3>, the end d forming the seating for a valve e, Fig. 3, the stem of which carries a slidable sleevepiston f adapted to abut a diaphragm g secured to the valve-stem or a washer f fitted between an extension f of the cylinder casing a<1> and a flange f<3> on the sleeve-piston f. The diaphragm g moves in an oil filled chamber g<1> and is variably loaded by a spring h surrounded by a bellows g<2>, the spring pressure being augmented by admitting oil under pressure through a pipe g<2> to the interior of a chamber g<4> containing the bellows, the oil-pressure being variable either manually or automatically. Alternatively the spring-pressure may be varied by external cams or levers. The interior of the bellows and the chamber g<1> are connected by passages h<1>, h<2>, h<3>, with an oil reservoir c above the cylinder a<1>. On movement of the piston a to the left the valve e is opened directly and liquid passes through the conduit to the opposite end of the cylinder while on movement of the piston to the right liquid passes through the conduit in the opposite direction and acts on the sleeve-piston f and thus on the diaphragm g to open the valve e. The diaphragm, due to its small annular clearance in the chamber g<1> damps any incipient valve-flutter.

Abstract: 885,759. Guns for firing blank ammunition. KONGSBERG VAPENFABRIK. Feb. 1, 1960 [Feb. 4, 1959], No. 3496/60. Classes 92 and 119. Relates to a recoil-operated gun, e.g. an anti-aircraft gun and to an arrangement for use when firing blank ammunition for practising so that the recoil and general behaviour of the gun is exactly as if ordinary live ammunition had been used. According to the invention the barrel 1 is slidably supported in a cylinder 2 and recoils against the action of a spring 3, the end of the cylinder being provided with a cap 5 forming an extension of the cylinder in which slides an annular piston 6 secured to the barrel. The barrel is formed with ports 9 leading from its bore to the inside of the cap 5 above the piston 6, so that the gas pressure drives the piston and barrel rearwardly to provide adequate recoil, the gases being exhausted through openings 12 in the cap 5. A choke 11 is provided in the bore of the barrel and the dimensioning and design of the choke 11, ports 9 and openings 12 are such that the gun behaves as if ordinary ammunition had been used. The barrel 1 is a practice barrel since the ports 9 and choke 11 render it useless for ordinary ammunition.

Abstract: 868,652. Electrically released switches. IGRANIC ELECTRIC CO. Ltd. Feb. 4, 1958 [Feb. 25, 1957], No. 3599/58. Class 38 (5). An electrically-heated retaining device 10 of a switch 11 is arranged so that the heat passes to a sleeve 24, preferably of brass, which is bonded by eutectic material 35 to a rotor 31 carrying a ratchet-wheel 34 acted upon by means within the switch which opens the switch when the material 35 melts and allows the rotor to turn. The device 10 connects terminals 17, 18 and the switch 11 controls the circuit between terminals 19, 20. The heater strip 16 (Fig. 3) has its portion which surrounds the sleeve 24 thinly coated with insulating material 29 such as a silicone compound, glass or ceramic substance. Mica washers 27, 28 are placed on each side of the strip and a thin stainless steel washer 30 prevents damage to the mica washer 27 as a flange 25 on the sleeve 24 is formed to retain the parts in position. The wheel 34 and flanged part of the rotor 31 prevent other than rotary movement and tend to prevent loss of the substance 35 on melting. The rotor is made of stainless steel and has a polished coating on its outer surface which tends to reflect heat back towards the eutectic material 35. In Fig. 6, three heating strips 42, 43, 44 are arranged with insulating strips 48, 49, 50, 51 so as to be electrically in series between terminal grommets 46, 45.

Title: Reducing zinciferous materials containing lead and other contaminating metals
IPC: C22B19/18
Filed: 1930-02-03
Abstract: 352,005. Extracting zinc. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(New Jersey Zinc Co. ; 160, Font Street, New York, U.S.A.) Feb. 3, 1930, No. 3669. [Class 82 (i).] In the extraction of zinc from zinciferous materials the substantial removal of lead and other contaminating metals such as antimony, tin, bismuth, germanium, thallium, aluminium, and magnesium from the zinc vapour is effected by passing the gaseous products of smelting through a medium at a regulated temperature maintained between 800 and 900‹ C. The medium which may be composed of one but preferably of all of the ingredients of the charge for smelting is used in crushed form or may be briquetted or sintered into aggregates about 3 inches in diameter, and is confined so as to move progressively through the path of the gases. The gaseous products issue as a continuous stream of zinc vapour and carbon monoxide relatively constant in volume and composition and particularly free from oxidizing gases. In the apparatus shown, the smelting of the agglomerated charge takes place in that portion of a retort 5 that is confined within a furnace structure 6 and heated by any convenient means. The gaseous products of the reduction pass through the cooler body of the charge in the portion 5<1> of the retort outside the furnace where the lead is removed from the zinc vapour on its way to a condensing chamber 11 by way of an offtake 10. The temperature of the eliminator is regulated by an adjustable thickness of insulating material 8. Fresh charge is introduced from time to time at the top of the retort and worked off charge removed at the bottom so that the retort works continuously. The deleading medium may be composed of material other than the ingredients of the charge, such as residues or rerractories, and may be confined in a chamber separate from the smelting chamber.

Abstract: 372,774. Centrifuging anti-rust linings in pipes. VEREINIGTE STAHLWERKE AKT.-GES., 69, Stahlhaus, Breitestrasse, D³sseldorf, Germany. Feb. 9, 1931, No. 4024. Convention date, April 1, 1930. [Class 87 (ii).] In a process for applying to pipes or tubes, a lining of anti-rust composition by centrifugal force, the pipes are supported on and driven by rollers which are first arranged with their axes parallel to the axis of the pipe, and are then skewed to move the pipe longitudinally whilst still being centrifuged. An electric motor may be embodied in each roller to drive it individually, and the rollers may be transversely adjustable to accommodate pipes of various diameters. The lining material is supplied to the pipe from any known form of container which may be movable. The pipe may be centrifuged first on a set of skewing rollers and then moved thereby to a second set of rollers, to make room for another pipe at the initial centrifuging position. More than two pipes may be accommodated on the rolls. The pipe may be cooled by a cooling liquid to hasten the hardening of the lining. The Specification as open to inspection under Sect. 91 (3) (a) describes apparatus, Fig. 3 (Cancelled), wherein each pipe a is rolled from a grate b on to arms c which lower it on to rolls d for the initial centrifuging, and is then lifted by the arms c on to a grate e over which it rolls to a second set of rolls d for the final centrifuging. In a modification, the grate e is dispensed with, rollers in three lines forming two centrifuging positions. In further modifications, skewed coned rollers move the pipe longitudinally. A device for supplying the lining material to the pipe comprises a wheeled container with a long horizontally extending discharge pipe which is passed into the pipe. This subject-matter does not appear in the Specification as accepted.
