摘要： 1,204,161. Retaining occupants in beds. GEORGE ELLISON Ltd. 29 May, 1968 [25 May, 1967], No. 24363/67. Heading A4J. A cot side comprises a plurality of links 11, 12, 13 pivoted at their ends 15, 24, 28 to a vertical support 10 mounted by a spigot and socket connection on a bed frame 35, and releasable means for holding the links vertically in inoperative position alongside the support 10. The links are telescopic and the pivot of the upper link 11 consists of a pin (21) extending between the limbs of the channel-shaped upper part 16 of the support 10 and passing through a slot 20 in the upper link 11. When the links are in the inoperative position the outer part 14 of the upper link 11 can slide downwardly on its pivot pin (21) and is then prevented from turning by abutment of its end (42) with the base of the channel member 16. The other ends of the links are pivoted at 19, 26, 31 to an end member 18 the lower end of which is received in one of a plurality of U-shaped members 38 secured to the bed frame. The downward pivoting of the links is limited by the left hand end of the middle link 12 abutting a pin 40 extending between the limbs of the channel member 16. The ends of all the links may be slotted for engagement with pivot pins. Two cot sides may be mounted at each side of the bed.

摘要： 1,187,038. Distribution boards. GEORGE ELLISON Ltd. 27 Nov., 1967 [3 Nov., 1966], No. 49332/66. Heading H2E. [Also in Division H1] In a distribution board, a laminated assembly of conductors and insulators similar to that of Specification 1,030,283, is modified to enable parts of the board to be interconnected or disconnected at will. Each layer of conductive sheet in the assembly is formed of at least two pieces of conductive sheet, e:g. 20, 21, separated by an insulative strip 23, so that there are two sets of mutually insulated conductive sheets in the assembly, viz. 11, 20, 33, 43 and 12, 21, 34, 44, see also Figs. 3, 5, 6 (not shown). A switch (not shown), having two sets of terminals connected through insulated holes in the laminated assembly to the respective conductivesheets, can be opened and closed to interconnect and disconnect the respectively conductive sheets in the two sets. If the board has two input transformers serving separate circuits on the board and one transformer fails or requires replacement, then this switch is closed to interconnect all the laminated assemblies in the board, enabling the entire load to be supplied by the one transformer. Typical connectors to terminals are 28, 29, 30, while typical connector stems between assemblies are 24, 25, 40 and 51, the latter being surrounded by insulating washers such as 19, Fig. 3 (not shown); or 32.

摘要： 1,030,283. Distribution assemblies; switchboards. GEORGE ELLISON Ltd. Jan. 15, 1965 [April 29, 1964], No. 17697/64. Headings H2B and H2E. A distribution assembly comprises sheets of conductive material 26 separated and surrounded by sheets of insulating material 14 -18, and connecting rods 24 permanently secured to the individual conductive sheets. Where the connecting rods 24 pass through conductive sheets 11 larger apertures are cut in the sheets 11 and filled with insulating rings 26. Several assemblies may be connected together at their edges by means of links 27 (Fig. 2, not shown) which connect together the corresponding conductive layers in each assembly. The assembly may be made from separate laminations, or by moulding or casting the insulating material in situ, between the sheets. The edges of the assembly may be protected by insulating strips 31 (Fig. 3, not shown). The width to thickness ratio of the conductive sheets exceeds 32: 1. The assembly may form the back panelling of a switchboard (Fig. 1, not shown) in which the terminals of the switches 19-22 are secured directly to the stems 24. Output connections 29 of some of the switches may take the form of rigid rods extending backwardly through apertures 28 (Fig. 4) provided in the assembly. Output terminals 30 (Fig. 1, not shown) and the connecting links 27 (Fig. 2, not shown) may have removable insulating covers.

Class 38 (v) A tank construction for an air-break switch having its contacts within a tank and its operating mechanism outside the tank, comprises a tank a, a cell or cells of insulating material for containing the contacts b, c, and a plurality of metal bodies g attached to the walls e or base of the cell or cells, the bodies having sufficient thermal capacity to effect by cooling the extinction of the arcs formed on separation of the contacts and the cell or cells and the tank being arranged to provide air passages open to the atmosphere. In the Figure the bodies g are attached to the walls e which are perforated and spaced from the walls of the tank to provide passages i.

[Class 38 (i)] [Also in Group XXXVII] A rigid member a having concentric an nular contact surfaces constituted by the walls of a groove c co-operates with a re silient plug member i having two annular sets of spring blades i one set pressing out wardly against the outer wall of the groove c and the other set pressing against the inner wall. The blade: are anchored in a groove h by a wedge-shaped ring j which is retained by bending the edge k of the groove. The co-operating contact members are located relatively by a central plug and socket m, n that engage before the contact members meet, the plug m being tapered. The groove c and sets of blades may be duplicated.

摘要： 480,462. Heavy-current switches. ELLISON, Ltd., G., and ANDERSON, J. Nov. 6, 1936, No. 30249. [Class 38 (v)] In order to neutralize the electromagnetic forces acting upon the fixed and moving contacts of a circuit-breaker of the kind in which a movable contact-member is adapted to bridge the ends of a pair of fixed contacts, the breaker is provided with an iron part or parts mounted on the movable contact-member and adapted to co-operate with a stationary iron part or parts mounted at any convenient position or positions. The invention is applicable also to isolating switches and any other allied apparatus for controlling heavy currents. The contacts may be immersed in a liquid, air, or gas. In Figs. 1, 2, the inner side of each main fixed contact c insulatingly carries an iron plate h, and an iron piece i is secured to and below the movable bridging bar a. The plates h are slotted so as to straddle the bar a, and piece i has upturned parts j which straddle the bar a and are bent similarly to the lower ends of plates h. The latter are similarly magnetized by the current in the adjacent fixed conductors and i is complementarily magnetized by the current in bridge a, the arrangement being such that the force between them may neutralize to any desired extent the repulsive forces between a, c. In Fig. 4, the plates h are flat and their slots embrace the ends of piece i, which in this case are turned up at right-angles. In Fig 5, iron plates h extend from opposite tank walls towards the bridge a and a pair of plates i are secured athwart the latter.

摘要： 480,025. Winding-apparatus. ELLISON, Ltd., G., and GOLDING, F. F. O. Sept. 24, 1936, No. 25932. [Class 78 (v)] [Also in Group X.XVIII] The helical cable groove of a winding-on drum is formed of a helical strip h which is slipped over the drum d and is riveted or otherwise attached at one end to a plate i formed on or fixed to the outer end of the drum. The helix forms a deep groove, and being unconstrained axially it grips the sides of the cable and assists in holding same on the drum. The cable end may be held to the drum by passing it through a transverse hole therein and clamping by a grub screw. The Figure shows a drum driven by a worm f, the cable j passing over a pulley k, for attachment to the oil tank of an electric circuit-breaker. U.S.A. Specification 1,850,677 is referred to.
