Title: Improvements in and relating to presses for moulding plastic and powdered materials
IPC: H01M4/10
Filed: 1929-10-29
Abstract: 340,679. Moulding battery elements &c. SCHLIECKMANN, H., 15, Wilhelmstrasse, Cassel, Germany. Oct. 29, 1929, No. 32854. [Class 87 (ii).] Depolarizing elements for batteries are moulded in a press in which the whole of the operations are carried out by means of a single hand-lever 11. Plastic material stored in a hopper 1 is delivered in measured quantities by a slide 16, Fig. 4, which is reciprocated by transverse movement of the lever 11 about a pin 50 on a spindle 12, the lever acting on a bar 49 which is connected through linkage to the feed slide and to an agitator which facilitates the passage of the material from the hopper to the pressing chamber. A ram 18 actuated by a loaded linkage 20, 21 coupled through a pawl 26 to the hand-lever 11 preliminarily compresses the material after which the pre-pressed block is pressed into the mould 14, a carbon rod 10 being forced forward relatively to the block by a plunger 53 controlled by the link 55. A spring- pressed pin 60 constitutes a yielding coupling between the rod 56 and the link 55 and is withdrawn by an adjustable stop 62 when the carbon rod has been advanced in the mould 14 till it contacts with an end stop 41. The stop 41, Fig. 8, is bored at 65 to allow surplus material to be displaced from the mould and is hinged, a locking slide 44 controlled by linkage from the shaft 49 being provided to retain the end stop in closed position. After the pressing operation the handle 11 is moved transversely to actuate the shaft 49 and so withdraw the locking slide, whereupon the plunger 10 is actuated to discharge the completed element from the mould.

Title: Trimethylolphenol-polyol thermosetting copolymers
IPC: C08G8/28
Filed: 1957-10-22
Abstract: Thermosetting resins derived from resin-free 2,4,6-trimethylol phenol and a water-soluble aliphatic organic compound containing a plurality of hydroxyl groups, when cured on a porous surface such as a cement or cellulose building board, from a base for oil and latex-base paints.  In Example (10) an aqueous solution of starch, 2,4,6-trimethylol phenol, clay and ammonium sulphamate is spread on to a cellulose board, air dried, and baked; a further coating of polyvinyl acetate was then applied.  In Example (12) an aqueous solution of 2,4,6-trimethylol phenol and 75% hydrolysed polyvinyl acetate was brushed on to a cement coated building board, air dried and baked; a green oil-base enamel paint was then brushed on and air dried.  In Example (14) an aqueous solution of 2,4,6-trimethylol phenol and polyvinyl alcohol was applied to a cellulose building board, air dried and baked; the green paint of Example (12) was then applied.  In Example (15) a methanol/water solution of a 31% hydrolysed polyvinyl acetate, 2,4,6-trimethylol phenol, phosphoric acid, mica and titanium dioxide was applied to two cement coated building boards; one of these was air dried, the other air dried and baked; both were then coated with a pigmented polyvinyl acetate latex paint by brushing.ALSO:Thermosetting polymers are obtained by the reaction of 2,4,6-trimethylolphenol which is free of resinous materials with a water-soluble aliphatic organic compound containing a plurality of hydroxyl groups.  Such polyols include ethylene, diethylene, pentamethylene, propylene and polyoxyethylene glycols, glycerine, pentaerythritol, sorbitol, inositol, sucrose, chlorinated starch, tapioca starch, hydroxyethyl cellulose, polyvinyl alcohol, hydroxyethyl polyvinyl alcohol and partially hydrolysed polyvinyl acetate.  The reaction may be carried out in one or two stages and preferably in aqueous solution in the presence of such acids as phosphoric, hydrochloric, sulphuric, oxalic or sulphamic or of such other acid-releasing substances as ammonium sulphamate or tris-(b -chloroethyl)-phosphate.  The methylol phenol may be utilized in solution, e.g. in water, a low M.W. alcohol (ethyl), water/alcohol mixtures (e.g. methanol or ethanol), a ketone (acetone) or dioxane, or it may be prepared in situ from the sodium or barium salt.  The resin may be cured by acid accelerators such as those mentioned above, and other additives include hexamethylene tetramine, stearic acid, asbestos, paper pulp, cotton flock, wood flour, glass fibres, mica, clay and TiO2.  Uses.-Coating cellulosic and cement building boards, masonry, bricks, plastics, metal or glass; laminating; adhesives; moulding, e.g. bottle caps or abrasives.

Title: Powder compact for nuclear reactor fuel elements
IPC: G21C3/64
Filed: 1958-10-16
Abstract: A nuclear reactor sandwich type fuel element is formed of a sintered mixture of uranium carbide and aluminium powders which is mounted inside aluminium cladding.  The composition, which contains at least 80% UC2 in the uranium carbide does not change dimensionally at high temperatures.  The carbide is formed by arc melting uranium and carbon in an argon atmosphere or by reacting carbon with UO2; this is then crushed, mixed with aluminium powder and cold pressed to form compacts which are heated in a vacuum furnace to 600 DEG C at low pressure.  Each fuel mass has an aluminium sheath of welded construction.  The aluminium inner surfaces are scratch-brushed to facilitate bonding and subjected to a pressure of 26 tons per square inch after which the elements are reduced in thickness by rolling.

Abstract: 489,760. Packages; wrappers. RADO, L. Dec. 2, 1936, Nos. 33062 and 33063. Convention dates, Dec. 2, 1935 and March 6, 1936. [Classes 94 (i) and 94 (ii)] In the production of air-tight packages, metal foil such as aluminium foil is coated with a thermoplastic mixture such as nitro-cellulose varnish and allowed to dry. After application to the article the seams of the package are sealed by heat and pressure and may be embossed. The foil may be coated on both sides, the melting point of one coating being different from that of the other. A sheet of paper may be interposed between the foil and the contents of the package. The foil may be reinforced by cellulosic material. The sealed part may be used to tear the package open. The Specification as open to inspection under Sect. 91 comprises also a description of apparatus for making the packets. In one form, heated dies having cavities conforming to the shape of the contents are brought together to unite the edges of the sheet. In another form, a web upon which articles are placed, is fed beneath another web which is adhered to it to form a continuous series of packets which may be severed. The dies may be shaped so as to form grooves in the overlapping parts of the sheets. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,248,619. Memory read-out system. MITSUBISHI JUKOGYO K.K. 1 July, 1969, No. 33262/69. Heading G4A. The invention relates to error detection in a memory read-out system. A disc 1 storing data in the form of concentric rings, transparent rings indicating a " I " and opaque rings indicating a zero, is passed between plates 4 through an optical detector. Detected signals having a large amplitude for " 1 "s and a small amplitude for "0"s are passed to a slicing circuit 7 and shaping circuit 8 to produce pulses indicative only of the " 1 "s and to an amplitude limiter 9 and a shaping circuit 10 to produce clock pulses indicative of all data. The clock pulses are fed to a counter 12 feeding a matrix 13 producing successive signals 13a-13c equal in number to the bits of data stored on the record and producing signals 13e-13a when the second half of the ring passes the detector and emits the data signals in reverse order. The " 1 " pulses are fed to A or D gates 11a-11c equal in number to the bits of information and are passed by appropriate gates enabled by the matrix to set flip-flaps 14a- 14c. When the repeat of the data is received the set flip-flaps are reset the data stored on the disc then being transmitted from the flipflaps to a register. In the event of only one " 1 " signal being received the flip-flap remains set and issues an error signal to an alarm device 17 via an OR gate 16.
