Title: Improved valve gear for engines
IPC: F01L13/02
Filed: 1932-08-27
Abstract: 392,794. Engine valve-gear. COSSART, L. R. C., 78, Rue des Poissoniers, Paris. Aug. 27, 1932, No. 24013. Convention date, Sept. 23, 1931. [Classes 122 (ii) and 122 (iv).] A valve-gear for a reversible engine comprises three rotary cams on a common shaft controlling the exhaust, admission, and cut-off respectively. The admission and cut-off cams act on rollers connected to a beam the centre of which actuates the valve which is open when both cams are in action. The admission and exhaust cams are simultaneously angularly adjusted to effect reversal; the cut-off cam is angularly adjustable. The reversal and cut-off may be effected by one or two independent controls. A shaft 8 carries a multiplethread screw upon which move longitudinally and rotate nuts 9, 10, 11. Links 15, 19, 20 pivoted at points 16, 21, 22 engage collars on the nuts. The nuts 9, 10, 11 control the exhaust cam 1, admission cam 2, and cut-off cam 3 respectively. The movement imparted by the links 15, 19 to the nuts 9, 10 to effect reversal is proportional to the required angular displacement of the cams 1, 2. The cam 1 actuates a roller 24 on the exhaust valve control rod 25. The cams 2, 3 actuate rollers 27, 28 on spring-pressed rods 29, 30 connected to a lever 31 which operates the admission valve. A modification is described wherein the reversal and cut-off are simultaneously controlled by a rack-actuated shaft provided with cam drums which move collars on sleeves on the nuts controlling the valve-actuating cams to effect their adjustment. The cams are mounted on a half-speed shaft driven through toothed gearing from the main shaft. The angular displacement and the number of bosses in each cam depend on the speed of the cam shaft. Methods of mounting the admission and exhaust valve actuating levers on common shafts are described. The gear may operate lift, flat, piston, or cylindrical valves.

The roller is covered by a sheet 7 of raised fabric, cloth or rubber. Pole pieces 4 may be omitted, with portions 13 being extended into contact with magnet 3. In another construction (Fig. 1 not shown) pole pieces 16 are replaced by wooden plugs connected by rods to pole-pieces 4, with tubular portions 12,13 being replaced by a non-magnetic tube. The roller may contain a plurality of magnets, each with polepieces 4.

Title: Improvements relating to the treatment of coal and cannel for obtaining products therefrom
IPC: C08F8/20
Filed: 1930-08-12
Abstract: Coal or cannel is chlorinated and extracted with suitable solvents such as benzene, chloroform, acetone, ether, carbon tetrachloride, carbon bisulphide, alcohol and pyridine.  The residue from the extraction on carbonization yields a highly absorbent carbonaceous mass.ALSO:Coal or cannel is chlorinated and the products extracted by suitable solvents such as benzene, chloroform, acetone, ether, carbon tetrachloride, carbon bisulphide, alcohol and pyridine. The extracted products are resinous in character and contain chlorine.  The chlorination may be carried out by passing dry chlorine through the finely divided coal, by dropping the finely divided coal through chlorine or the coal may be in suspension in a liquid medium, aqueous or otherwise, and the chlorine gas diffused through such medium or the chlorine may be prepared in situ.  In some cases the liquid medium may also be a solvent for the extraction enabling chlorination and extraction to proceed simultaneously.  After chlorination the hydrogen chloride that has been produced may be removed under a vacuum or by washing with water.  The residue from the extraction on carbonization is a highly absorbent carbonaceous mass.

Abstract: 1436705 Hydrophilic N-vinyl pyrrolidone copolymers NATIONAL RESEARCH DEVELOPMENT CORP 9 May 1973 [23 May 1972] 24147/72 Heading C3P Hydrophilic copolymers capable of absorbing water to form hydrogen comprise (a) N-vinylpyrrolidone, (b) an ethylenically unsaturated  hydrocarbon monomer and (c) a further ethylenically unsaturated hydrophilic monomer. Optionally alkyl or aryl (meth)acrylates and/or cross-linking agents may also be included. Component (b) may be an alphaolefin, arylolefin or isoprene, while (c) may be an alkenol or hydroxyalkyl(meth)acrylate.

Title: An improved catalyst and method of producing same
IPC: C07C51/10
Filed: 1947-09-02
Abstract: A composite catalyst of iron or an iron oxide and an alkali metal ferrate (see Group III), is used to synthesize hydrocarbons from carbon monoxide and hydrogen at temperatures between 450 DEG  and 675 DEG  F. and pressures between 100 and 500 pounds per square inch gauge.ALSO:A Fischer-Tropsch catalyst comprises a reduced mixture of a major proportion of iron or iron oxide and a minor proportion of an alkali metal ferrate.  The mixture is oxidized before reduction and both operations are conducted at elevated temperature.  The amount of ferrate varies between 0.2 and 20 per cent by weight of the iron component.  In examples, the ferrate is prepared by igniting a mixture of iron and potassium nitrate or by precipitating ferric hydroxide from ferric nitrate with ammonium hydroxide and oxidizing the hydroxide by solid potassium hydroxide and bromine.

Title: Improvements in locomotive axle boxes
IPC: B61F15/04
Filed: 1924-10-13
Abstract: 238,732. Blunt, J. G. Oct, 13, 1924. Adjusting for wear.-In an axle-box the inner side walls below the crown brass have recesses in which fit parts of the bolts used for adjusting the supplemental bearings. As shown, oppositely inclined faces 1h, Fig. 1, on the lower edges of the crown brass 1a of an axle-box 1 bear against corresponding faces on the axle-box and on the tops of the supplemental bearings 2. Recesses 1i in the inner sides of the box accommodate U- shaped bolts 4g the screwed arms of which carry nuts 4h, 4i for tightening the supplemental bearings and a lubricant cellar 3 respectively. The latter is positioned between the supplemental bearings so as to exert a wedging action to prevent the side walls of the axle-box from closing in. When the bearing wears, adjustment is made by filing down the inclined face on the top of the supplemental bearings and by, tightening up the nuts 4h, 4i. In a modification each U-shaped bolt is replaced by two T-headed bolts 4k, Fig. 7, and curved faces 3i on the lubricant cellar 3 bear directly on inclined faces 1o on the axle-box with walls. In another modification the outer sides of the supplemental bearings have recesses 2a, Fig. 15, to clear the heads 4c of bolts 4. The latter have cylindrical extensions 4d fitting into corresponding recesses in the side walls of the axlebox 1. On each side of the axle a bar 5 passes against a cam 6, one arm of which bears against an inclined face 2b on one of the supplemental bearings 2 and the other arm of which pivots in a recess formed by two inclined faces 1e, 1f in the axle-box. A lubricant cellar 3, having lugs 3b bearing upon the supplemental bearings, has curved corner faces 3a engaging inclined faces 7e on projections 7a formed on a supporting member 7, Fig. 20. The member 7 is formed in two parts, one part having a stem 7d slidable in a hole in the other part. Each part has a stop 7b butting against the bottom of the axle-box. Adjustment of the supplemental bearings 2 is obtained by screwing up the nuts 4e, the bar 5 which has an enlarged hole 5a being kept with its outer face hard against the face. 1e of the axlebox by the wedging action of the lugs 7a of the member 7.

The means for retaining a hinged ventilator panel 1 in open and closed positions comprises a pair of links 9 at the edge remote from the hinge one end of each link being pivotally connected to a slide 10 retained in a guide 11 along an edge of either the panel or its frame 2 and the other end of each link being pivotally connected to the other of these parts and associated with yieldable locking means adapted to retain the link in a plurality of relative angular positions, the locking means being adapted to yield automatically to permit the angular setting of the panel to be altered in response to a push or pull exerted on the panel. In the embodiment illustrated in Fig. 1 the links have a common pivotal connection with the other part, which is shown as the panel, and the yieldable locking means comprises bosses 14 on the links formed with opposed mutually co-operating sinuous serrations 18 urged into engagement by a coil spring (not shown) located in the boss of the lowermost link. A hand-grip 16 is provided on the panel. The serrations are arranged so that they do not quite reach a position of full mutual interlocking when the panel is closed, so that a continuous closing force is provided. In an alternative embodiment (Figs. 6 and 7, not shown) the links have separate pivotal connections with the panel, the boss 14 of each link being in spring-loaded engagement with a complementary serrated boss secured to the panel.
