Abstract: 846,006. Electrical storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1956 [Dec. 30, 1955], No. 39124/56. Class 37. A two-terminal storage device, similar to a coherer, consists of a body of granular conducting particles in an insulating binder and becomes conducting in response to the application of an appropriate voltage from a source 13 and non- conducting in response to current flow from a source 17 of lower voltage. The granular particles may consist of powdered iron, tin, aluminium or carbon the best result being obtained with metals whose oxides have a higher melting point than the -pure metal. The size of the particles is preferably less than 44 microns. The insulating binder may be of any suitable plastic material for example epoxy resin and may include an inert filler such as titanium oxide, asbestos, magnesium dioxide, silica gel, or ferric oxide. The binder and conductor should be present in roughly equal proportions. A slight trace of detergent material such as " Tergitol " (Registered Trade Mark) creates a more intimate mixture of the conductor with the binder.

Abstract: 989,723. Track circuit signalling system. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 6, 1961 [Nov. 15, 1960], No. 39153/60. Heading B7N. In a signalling system for controlling the passage of rail vehicles over a single stretch of track bounded by track circuit section AT, BT and including two normally energized relays 2SR, 3SR each associated with one direction of movement and a normally released master relay 1SR, the relevant direction relay, relay 2SR assuming left to right movement, is released when the route is set up and the master relay is picked up when the train enters the second track circuit BT and restoration of a route setting relay 1LR and disengaging signal stick relays ATSR, BTSR is prevented until the directional relay 2SR is re-energized via a circuit which includes a front contact of the master relay and a front contact of relay BTPR which is picked up when track section BT is vacated. Assuming left to right movement, route setting relay 1LR is reversed and releases relay 2SR. When the train enters section AT, track repeater relay ATPR releases and deenergizes disengaging signal repeater relay ATSR. The apparatus remains in this condition until the train enters track section BT when relay BTPR releases and energizes relay 1SR and releases relay BTSR. When the train leaves section BT, relay BTPR picks up and re-energizes relays 2SR and ATPR, approach locking relay ALSR is now energized and switches route setting relay 1LR to normal. Master relay 1SR now releases and the disengaging signal stick relays are re-energized.

[Class 97 (i).] Specimens or negatives in film or thin sheet form for use in the microscopic examination of the surfaces of solid objects are prepared by applying to and pressing against the surface a transparent plastic solution, such as an amyl acetate solution of celluloid, which adheres to the surface while solidifying and does not change its shape, the solution forming by evaporation of the solvent a thin transparent film which is impressed with a fascimile of the surface, and can be stripped off. The impression may be obtained by coating a thin celluloid sheet with the solvent and then applying it to the surface, the sheet being stripped off after the solvent has evaporated.

Title: Modified polymers
IPC: C08F8/12
Filed: 1956-12-24
Abstract: The viscosity-index of mineral oil based lubricating or hydraulic oils is improved by the addition thereto of the nitrogen-containing products obtained by the alcoholysis at temperatures above 1800 DEG C. of methyl methacrylate polymers with alcohols containing at least 8 carbon atoms in the presence of ammonia and/or amines, particularly amines containing at least 4 carbon atoms.  In an example (4) a lubricating oil additive is made by alcoholysing polymethyl methacrylate in mineral oil solution with a straight-chain primary alcohol of average C-number of 15.2 in the presence of cocosamine (a mixture of C10-C18 fatty amines).ALSO:Polymers of methyl methacrylate are subjected to hydrolysis and/or alcoholysis in the presence of ammonia and/or amines at temperatures above 180 DEG  C., preferably from 220 DEG  to 300 DEG  C.  In hydrolysis processes caustic potash, caustic soda, alkali metal carbonates, alkali metal acetates and lime may be used as hydrolytic agents.  In alcoholysis processes alcohols containing up to 20 carbon atoms may be used, including polyhydric alcohols, e.g. diethylene glycol, which give rise to cross-linked products. Amines specified are methylamine, butylamine n - hexylamine, n - octylamine, 2 - ethylhexylamine, diisobutylamine, cocosamine, morpholine and hydrotalgamine, which is the product obtained by reductive amination of long-chain fatty acids, e.g. tallow acids. The products, which contain nitrogen, may be used, depending on their nature as soil-improving agents, textile treating agents, thickening agents, additives for lubricating or hydraulic oils and, in the case of cross-linked products, ion-exchange resins.

Abstract: 1398729 Rolling spherical pellets V N BOCHANOV V A MINCHENKO and S S SCHIPITSIN 23 Aug 1972 39359/72 Heading B5A In an apparatus, for rolling a strand of material into spherical pellets, comprising a pair of parallel rollers 1 and 2 each having semicircular grooves 5 which co-operate to form a line of circular shaping grooves 6, a part of each groove surface 7 has a different coefficient of friction on material to be shaped from a diametrically and diagonally opposite groove surface. The different portions may be obtained by constructing the roller from a plurality of discs arranged so that alternate discs have relatively higher and lower frictional coefficients with the material being shaped, each pair of such discs forming the required semicircular groove at their periphery. Alternatively rings may be used, instead of discs, to form a hollow roller (Fig. 2, not shown).
Patent GB-1541813-A (GB)
Title: Copying apparatus
IPC: G03G15/26
Filed: 1977-09-23
Abstract: In copying devices with a revolving endless band coated with a photoelectric material, the duration of use of this band is approximately proportional to the band length. For using bands of great length and correspondingly extended duration of use, these devices contain a band magazine which has a large number of deflection elements which are arranged parallel to one another and around which the band is guided in a meandering manner. In order to extend the length of the band (6) which can be stored in the magazine, it is proposed to use, in addition to the previously usual two rows of deflection elements (29, 32), two further rows of deflection elements (30, 31) and to arrange the two additional rows between the two previous rows. As a result, it is possible almost to double the band length situated in the magazine without increasing the outer dimensions of the magazine. <IMAGE>

The slots 9 in the plate 10 are of length about half the wavelength of the microwave energy and are distributed over the whole or a substantial portion of the plate. and their number, position and width are chosen to produce a desired pattern of micro-wave field in the chamber 4. The slots 12 can be of different width, and radiation through one or more slots 12 can be adjusted by a capacitive impedance formed by an edge 14 of the plate 10 being bent over along the slot at right angles to the plane of the plate. The bottom wall 16, Fig. 2, of the chamber 4 can be in the form of a trough the depth of which is greater than one quarter wavelength of the micro-wave energy and which is covered by a plate 17, preferably in several pieces, of low-loss insulating material, such as non-laminated opal safety glass, for supporting the objects or substances 6. The slotted plate 10 can swing through about Œ (10 to 15) degrees about a horizontal axis 15 with a periodic time small in relation to the duration of heating. A trough-shaped projection 19 is provided in one vertical wall of the chamber 4 and is closed by a flap 21 pivoted at 20.
