Title: Improvements in or relating to electro deposition of chromium
IPC: C25D5/00
Filed: 1929-06-13
Abstract: 335,161. Gratze, E. V. Hayes-. June 13, 1929. Electrodes; supporting; connections; chromium, depositing.-In electro-plating an article with chromium using anodes of lead or lead alloy, auxiliary cathodes are employed to prevent excessive deposit on salient parts of the article. Insulating shields may be used in addition to deflect the ions and to prevent accummulation of pockets of gas. An arrangement for plating a concave article x, Fig. 3. comprises anodes a, a<1>, insulating shields c and auxiliary cathodes b electrically connected with the article a. Modified arrangements for plating articles of various shapes are described. The electrodes and shields may be movable and the electrolyte may be circulated mechanically or thermally. The auxiliary cathodes may constitute a frame on which the articles to be plated are mounted. In plating a perforated plate, an auxiliary cathode of sheet form is mounted on the side remote from the anode. An arrangement for coating the outer frame x, Fig. 9, of a motor car radiator comprises an anode a, shield c, auxiliary cathodes b, and resilient plates c<2> for closing the tubes x<1>. The tubes may be filled with water to which glycerine is added to increase the density above that of the bath.

Title: Improvements in and relating to the treatment of mixtures of pyridine bases derived from coal tar and other sources
Filed: 1944-09-28
Abstract: 2.3-Lutidine is separated from mixtures containing 2.3-lutidine, 2.4-lutidine and 2.5-lutidine by allowing the mixture to react with urea, whereby the 2.3-lutidine forms a crystalline compound with the urea which is separated from the mother liquor containing the 2.4- and 2.5-lutidines and is decomposed by heat to yield 2.3-lutidine. In an example, a lutidine fraction of boiling range 159 DEG  to 162 DEG  C. is treated with a 50 per cent aqueous urea solution and the mixture is allowed to stand at room temperature so forming crystals which are separated p  and steam-distilled.  The distillate is heated to 90 DEG  C., so separating it into an aqueous and a lutidine layer which is purified by distillation.

Abstract: 1378504 Riveting ALCAN RESEARCH & DEVELOPMENT Ltd 19 May 1972 [2 June 1971] 18697/71 Heading B3U A length of wire or rod 44, Fig. 6, is driven through sheet, or other material by clamping the material between a pair of dies 3, 21, Fig. 1, having aligned bores, placing the length of wire or rod 44 in bore 4 of the die 3, and applying pressure to the length of wire or rod by means of a punch 12 to compress it into a compact body conforming to the cross-section of the bore 4, if it is not already in the form of such a compact body, and to drive the compact body through the material. In operation two sheets are placed on a table 2 and the die 21 raised to clamp the sheet against the die 3. A shearing block 7 is then actuated to shear off a wire length 44 and transport it to a position in alignment with the bore 4. The wire length is then driven through the sheets, Fig. 6, by lowering the punch 12 until the latter is arrested by a stop 16. The die 21 is allowed to move downwardly after withdrawal of stop 16 and on continued lowering of the punch 12, the wire length is removed from the bore 4. The die 21 is then raised, Fig. 8, to form a rivet head 46. An extractor punch 23 is moved upwardly while die 21 is moved downwardly to bring the lower end of the wire length clear of the die 21. The die 21 is then moved upwardly to form a lower rivet head. Movement of the shearing block 7, the punches 12 and 23 and the die 21 is effected by respective hydraulically operated piston and cylinder assemblies operated by hydropneumatic boosters.

Title: Improvements in or relating to the manufacture of cellular bodies
IPC: C08J9/12
Filed: 1950-07-27
Abstract: Closed cell, cellular bodies are obtained from thermoplastic material by reducing such material to a finely-divided loose compressible state, adding one or more solvents or softening agents, introducing the materials into a mould having a movable ram, introducing gas under pressure, moving the ram into the mould so as to compress and compact the gas and materials, heating to enable the gas to be absorbed, cooling, opening the mould, and then expanding by heat if necessary to produce the cells.  The thermoplastic material may be rubber, polyvinyl chloride, polystyrol, or cellulose acetate and the solvents, acetone, ethyl methyl ketone, butyl acetate, cyclohexanone, tetrahydrofuran or benzol.  Softening agents may be tricresyl phosphate or dioctyl phthalate.  The material may be finely divided by grinding or used in the form of threads, sheets, plates or rods, it being placed in the mould in such a way that the gases can circulate; zinc stearate powder may be added to separate the parts. Small quantities of blowing agents such as azo-iso butyric acid dinitrile or diazoaminobenzene may also be added.  In examples (1) and (2), polyvinyl chloride optionally with tricresyl phosphate or dioctyl phthalate is converted to a fine powder with the aid of tetrahydrofuran.  The powder is then introduced together with nitrogen gas into a mould fitted with a ram.  Pressure and temperature is increased until the gas is completely absorbed after which the mould is cooled and opened.  The body after removal is expanded by heat.ALSO:Closed cell, cellular bodies are obtained from thermoplastic material by reducing such material to a finely divided loose compressible state, adding one or more solvents or softening agents, introducing the materials into a mould having a movable ram introducing gas under pressure, moving the ram into the mould so as to compress and compact the gas and materials, heating to enable the gas to be absorbed, cooling, opening the mould, and then expanding by heat if necessary to produce the cells.

Abstract: 147,132. Thiel, Geb., Ges. March 12, 1915, [Convention date]. Projectile fuses.- Relates to mechanical time fuses of the kind in which a spring striker 1 is retained cocked by means of a cam 3 on the striker resting on a fixed support 5 until an arm is released by the timing- mechanism and allows the striker to rotate, whereupon the cam 3 glides off the support 5 and the striker advances on a percussion cap (not shown). According to the invention, the arm 9 and the striker 5 are directly connected by means of a square extension 8 on the striker fitting into a corresponding hole in the hub of the arm 9, so that the striker cannot rotate until the arm 9 is released, but the striker moves downwards after release independently of the arm. The swing of the arm 9 is caused by the striker spring 2 as well as by centrifugal force; and a pivoted centrifugal safety 11 is provided to lock the striker until the projectile is discharged.
