Title: Improvements in or relating to oil testing apparatus
Inventor: BRIX VLADIMIR HERBERT
IPC: G01N33/30
Filed: 1950-01-31
Abstract: 678,456. Testing efficiency of lubricants. ROLLS-ROYCE, Ltd. March 14, 1951 [Jan. 31, 1950], No. 2553/50. Class 106 (ii). An oil testing apparatus of the kind in which a film of oil is tested between two relatively moving surfaces comprises a plane surface urged against the periphery of a disc, and means rotating the disc about its axis and causing a reciprocating movement of the disc relatively to the plane surface along a line at right angles to the axis of the disc, whereby the disc and the plane surface undergo both a rolling and sliding contact. As shown, the oil testing apparatus comprises a fixed structure 10, Figs. 1 and 2, in which a shaft 12 is rotated by a motor 13. The shaft 12 has a crank 12a with a crank-pin 12b connected to a circular disc 14 coaxial with the shaft 12 and supported in the structure 10 by a bush bearing 15. A bore in the disc 14 accommodates a layshaft 17. The layshaft 17 carries at one end a planet gear 18 meshing with an internally-toothed annular gear 19 fixed to the structure 10 and coaxial with the shaft 12. The pitch circle 18a, Fig. 3, of the planet gear 18 is half the pitch circle 19a of the annular gear 19, and consequently the distance of the axis of the layshaft 17 from the axis of the shaft 12 is a quarter of the diameter of the pitch circle of the annular gear 19. At the other end of the layshaft 17 is a crank arm 20 carrying integrally therewith a disc 22 on a pin 21, the axis of the pin 21 being parallel to the axis of shaft 12 and passing through the pitch circle 18a of the planet gear 18. As the shaft 12 rotates, the planet gear 18 rotates at the same speed but in the opposite sense. Also any point on the pitch circle 18a of the planet gear 18 will travel backwards and forwards along a straight-line path which is a diameter of the annular ring gear 19. A slide member 23 of trapezoidal section is mounted so that its plane parallel faces are parallel to the line of reciprocation of the disc 22, with one face in contact with the cylindrical surface of the disc 22 and with the other of the parallel faces engaging a partcylindrical member 24 (Fig. 2). When the slide member 23 is in contact with the disc 22, it is capable of rocking on the part-cylindrical member 24 to accommodate a small degree of misalignment between the contact faces of the disc 22 and the slide member 23. The pressure between the disc 22 and the surface 23 is adjusted by means 30 acting on springs 29.

Filed: 1972-01-19
Abstract: 1377781 Photographic process for producing relief images KOPPERS CO Inc 19 Jan 1972 [2 Feb 1971] 2673/72 Headings G2C and G2X A relief image is produced on the surface of a photo-polymerizable composition by imagewise exposing the said surface to actinic radiation for sufficient time to produce a volume contraction in the non-image (dark) areas. The composition comprises an alpha-beta ethylenically unsaturated polyester that is produced by polycondensing a dicarboxylic acid or anhydride which contains some alpha-beta ethylenic unsaturation and a dihydric alcohol and an ethylenically unsaturated monomer that is co-polymerizable with said polyester. The monomer may be a cross-linking vinyl or vinylidene aromatic monomer in which the condensate is soluble. The composition may contain a polymerization promotor. Suitable promotions are aliphalic polyamines of the formula: H(HNCR 2 CR 2 ) n NH 2  wherein H is hydrogen or lower alkyl (less than 5 carbon atoms) and n is an integer in the range from 2 to 4. Also useful as promotors are polyamide resins which are condensation products of aliphatic polyamines and unsaturated polymeric fatty acids. A free radical generating catalyst such as benzyl peroxide or t-butyl peroctoate may also be present. In a preferred embodiment the photo-polymerizable composition is contacted with a light absorbing layer, to form an interfacial surface between the composition and the layer, and actinic light is shone on the surface of the composition opposite to the light absorbing layer to form mirror relief images on the exposed surface and on the interfacial surface. The exposed composition may be treated with an organic solvent to deepen the image or may be heated after exposure to harden the relief.

Title: Improvements in and relating to internal combustion engines and the operation thereof
IPC: F02B3/00
Filed: 1950-02-02
Abstract: 691,055. Actuating materials; cooling charge. FEHLING, H. R., and FRIEDLANDER, G. Jan. 24, 1951 [Feb. 2. 1950], No. 2710/50. Class 7 (ii). In two- and four-stroke engines, extra power when required is supplied without significant increase in cylinder pressures by injecting a combustion supporting agent, vaporized from a liquid consisting wholly or partly of oxygen, into the cylinder or cylinders during or immediately following the compression stroke in addition to the normal air charge which is cooled before introduction into the cylinder or cylinders by heat exchange with the cold agent, and by the injection of further fuel in addition to the normal fuel charge, the charge proportions preferably being such that the total amount of agent and air is largely in excess of the theoretical amount required for complete combustion. The agent may be air or other nitrogen-oxygen mixtures, preferably containing more than 35 per cent. of oxygen, or nitrogen peroxide, and is preferably injected, at least partly, prior to the fuel..The heat exchange means may be of the surface or direct contact (e,g. jet) type, and the exchange may be effected in one or more stages, e.g. before and after compression of the air in supercharged engines. The heat exchange means may supplement separate agent vaporizing means such as those shown in Specifications 551,859 and 592,330. As applied to a four-stroke diesel engine supercharged by a blower 3, Fig. 1, liquid agent is drawn from a lagged reservoir 4 by a pump 6 and passed via a lagged pipe 8 to the inlet manifold 2 where it is vaporized in passing between headers 11, 12.

Patent GB-565815-A (GB)
Title: Process for producing artificial fibres, ribbons, films and like products of subdued lustre
IPC: D01F2/00
Filed: 1943-02-22
Abstract: Fibres, films and like products having a subdued lustre are obtained by extruding a fibre-forming polymer or a solution of same, e.g. regenerated cellulose, a fatty acid ester or ether of cellulose or an unsaturated compound such as polystyrene, polymethyl methacrylate, polyvinylidene chloride, or polyvinyl chloride acetate, containing a water insoluble condensation product of an aldehyde with an amino triazine, e.g. formaldehyde, acetaldehyde, benzaldehyde, or furfural, with melamine, ammeline, or ammelide.  The fibres or films are extruded into a zone where setting occurs by evaporation of the solvent, by solution of the solvent in a liquid in which the polymer is insoluble, by chemical action, or by cooling.  The condensation product is prepared by reacting the amino-triazine with the aldehyde in neutral or acid aqueous solution.  Catalysts employed are weak mineral acids, organic acids or a salt of a volatile base with a less volatile acid, e.g. ammonium tartrate.  As an example, powdered melamine and formaldehyde are warned for one hour at about 55 DEG  C. Glacial acetic acid is added and the whole is poured into water.  The resulting solution is warmed to 80-90 DEG  C., when a precipitate forms which is filtered off, dried, and incorporated by milling into a solution of cellulose acetate in acetone.  The fibres are then produced by a dry spinning operation.  Fibres or yarns produced as above may be dyed with dyestuffs such as 1-methyl-amino - 4 - phenyl - amino anthraquinone or 1-phenylamino-anthraquinone or dyes of the diamino-anthraquinone series to produce dyeings of very good fastness both to light and to the combustion products of coal gas.  Azo dyes may also be employed.
