Abstract: 1,101,227. Laminates and laminating. DOW CHEMICAL CO. 30 Sept., 1965 [7 Oct., 1964], No. 41609/65. Heading B5N. Laminates of thermoplastic material consisting of multiple layers of different materials, arranged alternately or in recurring sequences, are made by extruding the materials, as from nozzles 11, 12, into a casing 13 formed with internal manifolds communicating with a central distribution block 35, Fig. 3. The block, arranged vertically in the casing 13, has channels 36, 37, alternately arranged and connecting the manifolds respectively with a hollow " transition piece" 17 so shaped as to provide a delivery passage of constant cross-section throughout and changing from a vertically rectangular entrance to a horizontally rectangular exit, the central cross-section being square The alternate, vertically arranged streams of material delivered by the distribution block are spread out by the transition piece into superposed layer s20 which may be cooled at 22 and wound up at 23. Apparatus with triple manifolds and a three-channel distribution block is described, as is also a transition piece of similar function to the piece 17 but of simpler, generally triangular shape. In an example a laminate, comprising 125 alternately arranged layers of polystyrene and polymethylmethacrylate 10 cm. wide and 3À2 mm. total thickness, was produced from two extruded streams of the materials. Other material combinations mentioned are: polystyrene - green tinted nylon, polypropylene - P.V.C., polypropylene - polystyrene, ethylcellulose - polystyrene, polythene - polystyrene, polythene-polypropylene, and P.V.C. - vinyl chloride and vinylidene chloride copolymer. The thickness of individual layers is determined by the size of the related passages and the rate of delivery of the initial streams of material.

Title: Improvements in sheet material for forming laminated dielectric bodies
Inventor: JOHANNES NORBERT
IPC: H01B3/00
Filed: 1962-11-09
Abstract: A thin non-porous sheet material, e.g. a metal foil or an organic plastics film such as polyethylene film, which may be a coating on a metal foil, has at least one surface to which particles of a finely divided insulating material. e.g. an organic polymeric or inorganic material, adhere in such a way as to form projections thereon so distributed that when the sheet material forms part of a laminated dielectric body, for use as the dielectric of capacitors and cables and intended for subsequent impregnation with insulating oil or compound, a thin layer of the impregnating oil or compound can penetrate between the surface and the contiguous surface of the laminated body.  The particles may be randomly distributed and may be embedded in a thin adherent coating of a film-forming material in an amount and in particle size so that at least a substantial proportion of the individual particles or groups of particles are spaced from all other particles or groups of particles to form isolated projections. The particles may be of an average particle size at least twice the thickness of the coating.  The coating may be applied in the form of a dispersion of the particles, e.g. antimony oxide, alumina, silica, magnesia, polyethylene, polypropylene, or cellulose derivatives, in a film-forming material, e.g. cellulose acetate or polystyrene, by dip-coating, roller-coating or spraying during which operation the dispersion may be rapidly stirred.  Alternatively, the particles may be applied by flame-spraying or by pressing the particles in the form of a dry powder into the film under heat and pressure.

Title: Improvements in the method of, and apparatus for producing deionized product liquid by differential solvent transfer through membranes
IPC: B01D61/42
Filed: 1965-10-07
Abstract: In a method of producing a deionized product liquid from an ionic solution in a multi-membrane electrodialysis cell comprising a pair of spaced electrodes 12, 13, and at least one group of membranes, each group consisting of a pair of filter membranes A and a centre membrane B of smaller pore size, ionic solution is introduced into the chambers 15 formed between the groups of membranes, and between the membranes and the electrodes, and a reversible D.C. voltage is applied to the electrodes.  As shown in Fig.1 the electrodes 12, 13 are made anodic and cathodic respectively, and the membrane B is cathode permeable, and hence cations plus solvent pass through the left hand filter membrane A into the chamber 23, the cations then passing through the membrane B to the chamber 24 and hence through the right hand filter membrane A to the adjacent chamber 15, a smaller amount of solvent accompanying the cations in their passage through the membrane B than through the left hand filter membrane A. Hence de-ionized solvent accumulates in the chambers 23 and is withdrawn via outlets 25.  Higher hydraulic pressure is maintained within the chamber 15 than in the chambers 23, thereby forcing the membranes into physical contact with one another so that the chamber 23 comprises a thin film of liquid between the membranes.  After a period of time the polarity of the electrodes is reversed by means of switch 34, de-ionized solute then being removed from the chambers 24, via outlets 26.  Means may be provided for automatically discarding a portion of the product liquid after reversal, comprising a <PICT:1122636/C6-C7/1> quick action-slow return valve 41 Fig.2 (not shown).  Outlets 25, 26 may be connected to a single outlet, either directly Fig.3 (not shown) or via a solenoid operated valve member (43) Fig.2 (not shown).  The membranes B may be formed with surface channels 70 and the electrodes may be separated from the remainder of the interior of the housing by single membranes (69) Fig.7 (not shown).

Abstract: 1392573 Two part couplings BODENSEEWERK GERATETECHNIK GmbH 19 Sept 1972 [30 Sept 1971] 43416/72 Heading H2E A plug and socket coupling has main contact pins (18) and contact bushes (24) and also monitoring contact pins (20) and bushes (22) respectively, the monitoring contacts being arranged around the peripheries of the plug and socket, with the monitoring pins being shorter in length than the main pins and/or the monitoring bushes being shorter in length than the main bushes. The monitoring contacts are connected to an e.m.f. and a warning signal so that if the plug and socket are insufficiently mated to connect the shorter monitoring contacts the signal is actuated. In a further embodiment, the monitoring contacts are of two lengths (i.e. pins and/ or bushes of two lengths) to give a differential warning-thus when effecting mating both length monitoring contacts are connected but while in use a limited slackening between the plug and socket is permitted, sufficient to disconnect the shorter monitoring contacts without actuating a warning, further slackening separating the longer monitoring contacts at a point when connection between the main contacts is inadequate to actuate the warning signal. The signal may consist of a lamp which is extinguished when the monitor contacts become disconnected, or a relay or transistor operated lamp or hooter which become energized when the monitoring contacts are disconnected. A plurality of plug and socket couplings may be provided with a common selector switch (52) with the monitoring contacts of the plugs and sockets being connected together in series to an e.m.f., while current is tapped off between adjacent couplings and fed to the switch which has a signal for each coupling.

Abstract: 970,211. Hatch covers. INTERNATIONAL MACGREGOR ORGANIZATION. Dec. 16, 1960 [Jan. 6, 1960; March 2, 1960; Sept 21, 1960], No. 43427/60. Headings B7L and B7S. [Also in Division E2] A hatch-cover section P, which rolls along the coaming tracks 3 on rollers 2 is lowered to bring the sealing strips e into engagement with the upstands b, in the hatch closed position, by allowing the rollers 2 to drop into the openings 9 in the tracks 3. This is effected by a retractable member 6 which is pivoted to the position shown in chain-dotted lines by the hydraulic jack 19, electric motor or winch. The member 6 is formed with a hook 13 which, during the movement to the retracted position, engages a catch 14 on the cover-section to lock the section in the hatched-closed position. All the members 6 located at one side of a hatchway are operated in unison by the connecting-rod 23, or a cable or chain, which is moved in opposite axial directions by a jack 19 located at each end of it. In a further embodiment the retracting member is moved in a vertical plane normal to the roller track by a cam surface on the connecting-rod, the hook being a separate member which is moved to a locking position by a projection on the connecting-rod. A further embodiment describes a retractable member hinged to the hatch coaming which is moved to the retracted position by an eccentric segment which is rotated by the connecting rod. In this case the sections are locked in the closed position by a spring-loaded eye-bolt which is located over the end of the roller axle. Another embodiment describes a retractable member which is moved in a vertical plane normal to the roller track by a connecting-rod operating through a crank linkage. The locking member in this case being either an eye-bolt or U-bolt which is hinged to the top plate of the retractable member and which is moved to lock the roller axle by engagement with the edge of the opening, in the roller track, through which the member passes. The Specification also describes an arrangement in which the rollers on which the cover-sections move are mounted on the retractable members. All the retractable members may be mounted on a beam, extending alongside the hatchway, which is moved up and down by hydraulic jacks. A further embodiment describes the retractable member pivoted through an arm to a connecting rod so that axial movement of the rod moves the member up and down. In this case the sections may move along the coaming on a stud or roller which is trapped by a projection on the member in the sectionlocked position. The Specification envisages various combinations of features disclosed in the different embodiments.
