Patent GB-378743-A (GB)
Title: Manufacture of tertiary nitriles
IPC: H01K3/02
Filed: 1931-12-10
Abstract: Secondary nitriles are treated with an alkalimetal alkyl or aryl compound, preferably in the presence of a solvent such as ether, benzene or ligroin, and the resulting nitrile-alkali metal compound is then treated with an alkylating agent, whereby the tertiary nitrile is formed.  The alkali-metal alkyl or aryl may be prepared in a suitable manner, e.g. from sodium and mercury diethyl or chlorobenzene, in the same solution to which the secondary nitrile is to be added; the nitrile may even be present during the preparation of the metal alkyl or aryl if such conditions are maintained that the alkali metal does not react directly therewith.  The examples describe the treatment of sodium with mercury diethyl, butyl chloride, and chlorobenzene, and the preparation of diethyllylacetonitrile from diethylacetonitrile, diallylisoamyl acetonitrile and triallylacetonitrile from diallylacetonitrile, ethyldiallylacetonitrile from ethylallylacetonitrile, and ethylbutylallylacetonitrile from ethylbutylacetonitrile.

Filed: 1922-12-18
Abstract: 208,639. Boby, Ltd., R., and Griffiths, C. H. Dec. 18, 1922. Openers &c.-Fibrous material, such as the tow delivered from scutching-machines, is teased and cleaned by a conveyer provided with slats carrying pins which are caused to oscillate about axes transverse to the direction of motion of the conveyer. The slats K, Figs. 1 and 3, are provided with pins K' and are mounted in brackets J secured to the belts. Lugs M mounted on the trunnions L of the slots are adapted to contact with tappets Q mounted on the side frame and cause the oscillation of the slats.

Abstract: 1,015,271. Welding by fusion or pressure. F. HIRSCHMANN. Aug. 31, 1964 [Aug. 31, 1963], No. 34492/63. Heading B3R. In an automatic welding machine, a stationary drive rotates the welding head, e.g. arc, electron beam, ultrasonic vibration or laser type, about the work and produces a further linear movement of the welding head and a drive rotating with the welding head applies additional movement to the welding head. A carrier 8 is rotated by a stationary motor 11 around the work 1 held in a fixed chuck 2. A non-consumable electrode torch 4 to which filler wire is fed from a reel 7 or a consumable electrode torch is mounted on an oscillator 5 producing oscillation transverse of the weld. The oscillator 5 is mounted on the ram of an actuator 6 which may be controlled by the arc voltage. As the torch 4 is rotated gearing 14 acts on a follower 15 and adjustable cam 16 to move a slide 20 carrying the actuator 6 parallel to the axis of rotation. Micro-switches 18, 19 controlling the welding operation are actuated, when the carrier 8 has rotated through a predetermined angle, to stop the welding and to return the carrier to its original position. The supply cables and pipes for welding and control current, water, air and shielding gas coil around a drum 12 as the carrier 8 rotates. The cam 16 may be replaced by a template, e.g. for welding pipe intersections. The machine can produce helical welds or, if the linear movement is perpendicular to the axis of rotation, spiral welds. High-frequency starting, and automatic tracking of the weld seam may be incorporated.

Title: Improvements in or relating to the springing of vehicles
IPC: F16F1/22
Filed: 1928-11-23
Abstract: 316,857. Bernaerts. H. F. J. Aug. 3, 1928, [Convention date]. Vibration-dampers. - A vibration-damper for attachment to a leaf spring of a vehicle is constructed so that displacement of the spring induces increased pressure between the leaves. Surrounding the spring 1 is a stirrup 2 whose arms have notches 3 for the reception of the trunnion 4 of the cross-bar. The latter has an eccentric middle part 5 which presses against the lower plate of the spring. On the end 6 of the crossbar is clamped a lever 7 pivoted at 8 to a connecting rod 9 adjustably pivoted to the chassis member 11. A set-screw 13 having a hardened point penetrates the upper leaf and prevents longitudinal movement of the apparatus, while permitting it to tilt slightly. The stirrup or part of the transmiting-mechanism may be formed as a spring, or a spring may be inserted into the transmitting-mechanism. Movement of the spring in either direction from normal causes the cross-bar to rotate and causes the eccentric part to bear with gradually increasing pressure on the leaves of the spring.

Title: Improvements in the manufacture and production of aliphatic and cycloaliphatic saturated sulphinic acids
Filed: 1928-11-26
Abstract: 321,843. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 26, 1928. Sulphinic acids are prepared by causing sulphur dioxide to act on open chain aliphatic or cycloaliphatic saturated hydrocarbons in the presence of an anhydrous halide of aluminium or boron, preferably at pressures above atmospheric pressure and at elevated temperature. Mixtures of hydrocarbons such as benzine, ligroin and the like are particularly suitable. The Specification gives an example in which sulphur dioxide is forced into a mixture of 100 parts by weight of n-pentane and 50 parts anhydrous aluminium chloride until the pressure reaches 25 atmospheres. The whole is then warmed to 50-60 Centigrade. The product is precipitated with caustic soda. The sodium salt of the sulphinic acid, which forms colourless crystals, is worked up in the usual manner and the free n-pentane sulphinic acid is liberated with sulphuric acid and extracted with ether. A further example gives the preparation of cyclohexane sulphinic acid from cyclohexane, sulphur dioxide and aluminium chloride.

A shock-absorbing air cushion for a load (not shown) falling to the ground, comprises at least one surface having sufficient porosity to permit escape of air under slight cushion internal air pressure, and at least one outlet valve 36, or like opening, for escape of air under a higher cushion pressure. As shown, the cushion is formed from top and bottom panels and side walls, all of canvas, .which thus constitutes the porous surfaces. The cushion is divided by internal canvas diaphragms, Fig. 1 (not shown) into six compartments, each having a respective inlet valve 31, and respective outlet valves 36, Figs. 4 and 5, Each valve 31 comprises a respective opening 34 in the canvas base and a canvas flap valve member 31a reinforced by a vulcaned fibre panel. Cross bracing tapes 35 are stretched across the openings 34 beneath which a plywood frame 12 is retained by canvas pockets 13-16. The outlet valves 36 comprise an opening 36a and a flap 38 of similar construction to the flaps 31a of the inlet valves 31. The flaps 38 are adapted to be closed under slight internal cushion pressure. Under high internal pressure, following impact of the cushion with the ground, the flap 38 is blown through the opening 36a to cause a more rapid deflation of the cushion. On descent of the cushion, escape of air through the porous surfaces is made up by entry of air through the inlet valves 31. A plurality of cushions may be secured together by lacing.
