Title: Improvements in or relating to jacks
IPC: B66F3/24
Filed: 1937-05-11
Abstract: 487,909. Jacks; hydraulic load-handling machines. MERCIER, J. May 11, 1937, No. 13374. Convention date, May 11, 1936. [Class 78 (iii)] [Also in Group XXIX] Control mechanism for hydraulic or pneumatic jacks is mounted on the moving ram. Fig. 2 shows one construction in which a ram 2, carrying a piston 3 fitted with packing on both sides, moves in relation to a fixed cylinder 1 and applies a pulling or pushing force to a member attached to the eye 5. A lever 6 on one end of the ram may be operated by hand or power or automatically by devices such as thermostats or speed indicators to control the position of a sliding sleeve 16 through a connecting link 25. When the sleeve is moved towards the left, the ports 17 and 18 are brought into register to admit fluid from the pipe 11 to the right-hand side of the piston through the duct 19, thus moving the ram to the left. Meanwhile fluid from the left-hand side of the piston is expelled through the ducts 21, 20 to the exhaust pipe 12 passing through the ports 23, 24 which are brought into register by the same movement. On moving the sleeve to the right, ports 17 and 18 come into register to admit fluid to the left-hand side of the piston to move the ram towards the left, and the fluid from the other side escapes through duct 19 and ports 24<1>, 23'. Movement of the ram in either direction ceases whenever the handle 6 is brought to a central position. In the modified form shown in Fig. 1, the piston 3 is moved by power in one direction only, i.e. towards the left, and is returned automatically by the pressure in a reservoir 15. In this case the pivoted lever 6 controls two spring valves 8, 9 simultaneously so that in one position it establishes communication between the pressure main 11 and the right-hand side of the piston and in the opposite position opens up communication between the piston and the exhaust pipe 12. The jack is particularly adapted for operating the wing flaps and retractable radiators of aircraft.

Title: Manufacture of compounds of the aetio-cholanic acid series
IPC: C07J3/00
Filed: 1938-05-05
Abstract: 514,437. Aetio-cholanic acids. SOC. OF CHEMICAL INDUSTRY IN BASLE. May 5, 1938, Nos. 13422 and 13423. Convention dates, May 5, 1937, and April 14, 1938. Addition to 482,321. '[Class 2 (iii)] Compounds of the aetio-cholanic acid series are prepared from saturated or unsaturated genins of heart glucosides by treatment with an oxidizing agent. In the case when a mild oxidizing agent is used, #-keto-carboxylic acids are first produced, and these are subjected to acid scission by means of a strong alkali or an alkali alcoholate. The process is a modification of the process of the parent Specification. Parent materials mentioned include digoxigenin, sarmentogenin, digitoxigenin, gitoxigenin, periplogenin, uzarigenin, thevetigenin, calotropagenin, strophanthidin, and oubain. Oxidizing processes mentioned include treatment with ozone and scission of the ozonide, the action of peroxides such as benzoperacid and hydrogen peroxide, preferably in the presence of osmium tetroxide, or addition of two hydroxyl groups at the #-gamma unsaturated linking of the gamma-lactone ring followed by scission by chromic acid or lead tetra-acetate of the glycol thus produced. All the above treatments lead to the intermediate formation of a #-keto carboxylic acid which requires to be split by acid scission. Alternatively the oxidation may be carried out by more drastic agents such as chromic acid or potassium permanganate which lead directly to the required aetio-cholanic acid. If the acid which is produced contains tertiary hydroxyl groups these may be removed completely or in stages with the formation of nuclear unsaturated acids by means of agents splitting off water such as aqueous alcoholic mineral acid. The elimination of water can also take place with the acid scission. The unsaturated acids may, if desired, be hydrogenated. In an example, dioxigenin diacetate is oxidized with ozone in glacial acetic acid solution. The product is treated with water and then decomposed with alcoholic potash to give 3 : 11 : 14-trioxyaetiocholanic acid. Water is eliminated by treatment with aqueous-alcoholic sulphuric acid and the product shaken with cold alkali lye. The aqueous portion is subjected to a purification treatment to give pure 3 : 11-dioxyaetiocholanic acid.

Title: Improved manufacture of tapering tubular articles of clay and the like particularly chimney pots
IPC: B28B21/86
Filed: 1921-05-12
Abstract: 180,200. Smith, R. H. May 12, 1921. Extrusion machines.-Tubular articles of clay such as chimney pots are manufactured by expanding a tubular length of clay over a tapering core within a mould. Clay is forced through an annular shaping-space g provided between a fixed core f and a fixed die e, which is attached to the upper end of a mould a. Initially a core d is moved up into the mould a, its upper tapering part bedding against the lower end of the fixed core, and as the clay is fed the core is lowered until the clay tube reaches the lower end of the mould. The core d is then raised and the clay tube is thereby pressed into contact with the inner surface of the mould a, displacing the initially thickened parts of the wall to compensate for the increased diameter. The article so obtained is removed, after lowering the core d, by opening the mould a which is in two parts a<2>, a<3> hinged to a support a<6> at a<4>, a<5>.

Title: Improvements in or relating to apparatus for playing games
IPC: A63F9/00
Filed: 1928-05-09
Abstract: 316,695. Wareing, J. May 9, 1928. Arresting a moving model by competitive control.-In a games apparatus an object moves over a track and is adapted to be stopped by the players only when two or more of them simultaneously operate their separate control devices; the control devices may be electrically, mechanically or pneumatically operated. A model train C, Fig. 1, running on a track B is set in motion by a handle D<2> and then allowed to run freely, its position being denoted by an indicator K. A number of electromagnets G situated beneath a copper disc J fixed on a spindle D connected to the train are arranged in series with a battery and a number of resistances. Players closing push buttons E cut out the resistances, increase the current flowing through the electromagnets and so cause them to exert a braking effect on the copper disc J. In a modification, the train, which may be clockwork driven, is made principally of magnetic material and the electromagnets are situated immediately below the track. In a combined mechanically and pneumatically controlled braking system, a pneumatic tube N, Fig. 4, is connected to a flexible braking strip L and is displaced upwards on pressing pushbuttons E to which it is connected by Bowden wires P, it being necessary to operate at least two push buttons simultaneously to raise the strip sufficiently to come into braking engagement with the train C. The braking may be effected in an entirely mechanical manner by omitting the tube N and connecting the wires P directly to the flexible strip, or in an entirely pneumatic manner by replacing the buttons E and wires P by pneumatic bulbs and tubes respectively, the tubes being connected directly to the tube N.
