Title: Improvements in and relating to motor horns
IPC: G08B3/06
Filed: 1920-11-15
Abstract: 175,405. Master, S. D. Nov. 15, 1920. Horns, construction of and fluid supply for.- Relates to motor horns, and consists of a casing 10 provided with an opening 11 at one end through which communication is made with the mouth 12. A piston 14 is arranged within thecasing 10 and is connected to the piston-rod 15. The piston 14 is hollow and open at one end; it is provided with an annular groove 18 in which a rubber packing-ring 19 is secured by pins or the like, as shown at 20, to the walls of the groove 18. Communication is established between the interior of the piston 14 and the groove 18 by openings 22. In operation, the piston is driven quickly toward the opposite end of the casing and the air within the casing is expelled, sounding the horn, the air also entering the groove 18 through the opening 22 to expand the ring 19, which presses against the walls of the casing, to prevent leakage. When the air is expelled from the casing a vacuum is created, and, as the air enters through the mouth 12, it gradually returns the piston to the normal position. In a modified form, one end wall of the casing is provided with a plurality of openings, which are covered by flap valves, through which the air enters after the horn has been sounded. A method of normally holding the piston adjacent to one end of the casing by a plurality of coiled springs is also described. In a modified form of piston in which both ends are closed, one end is provided with openings which admit air into the piston. In a modification, Fig. 7, the rubber packing-ring 43 is supported upon the metal ring 44 which is also provided with a plurality of openings 45 for the admission of air beneath the ring 43.

Title: Process for the recovery of sulphur from hydrogen sulphide
IPC: C01B17/04
Filed: 1952-12-19
Abstract: In recovering sulphur from hydrogen sulphide by interacting hydrogen sulphide and sulphur dioxide in two catalyst stages using a granular catalyst in fixed beds, the first stage being carried out at a temperature of about 300 DEG C. or higher such that sulphur is produced as a vapour and the second at a lower temperature such that sulphur is deposited on the catalyst, sulphur being separated from the gases leaving the first stage before passing them to the second two catalyst chambers are used in the second stage alternatively for reaction and regeneration.  The hydrogen sulphide is reacted with sufficient sulphur dioxide to convert all the hydrogen sulphide being treated to sulphur and water vapour assuming complete reaction, i.e. the minimum ratio of hydrogen sulphide to sulphur dioxide is 2 : 1 by volume.  The catalyst may be alumina, bauxite or bauxite promoted with iron oxide.  The temperature in the second stage reaction may be maintained at 150 DEG  C.  The gases resulting from the second stage reaction may be used, after heating, in the regeneration process.

Filed: 1959-09-23
Abstract: 880,126. Aircraft. VARDEN, B. J. Sept. 23, 1959 [Nov. 5, 1958], No. 32352/59. Class 4. An aircraft power plant mounting comprises power plant supporting means rotatably mounted in a housing attached to the airframe, an articulate linkage rotatably mounted within the housing and connected at one end to the supporting means, and means for rotating the linkage to control the orientation of the power plant. In the Figure an engine 30, is mounted on a support 62 having a flange rotatably received in a housing 60 forming a universal spherical joint with a surface 58 on one end of a housing 42. The other end of housing 42 is universally mounted by a Hooke's joint 44 to a housing 32 depending from the underside of an aircraft wing 24 or fuselage. Four fluid pressure jacks 78 (two shown) interconnect lugs 82 or housing 32, and 74 on housing 42, and determine the angular disposition of housing 42 relative to housing 32. Similarly, four jacks 88 (two shown), determine the relative angular position of housing 60 relative to housing 42. A flexible linkage 98, as described in Specification 880,127 extends between the support 62 and a gear 106, rotation of the latter causing corresponding rotation of housing 62 relative to housing 42. The orientation of the engine 30 can thus be varied to produce lift, propulsion, and control forces. Supply lines for the jacks run between housing 32 and an inner housing 38 supporting the linkage 98. Fuel and electric supply lines for the engine run through the centre of linkage 98. Two engines are mounted in this way beneath each wing of the aircraft, and the linkages 98 of all four are controlled simultaneously from a manual control station by shafting and bevel gears, and chain and sprocket drives.

Title: Method and apparatus for spreading or converging a band of fibres  or threads
IPC: D02J1/18
Filed: 1970-07-03
Abstract: 1323091 Mechanical treatment of fibres POLYMER PROCESSING RESEARCH INSTITUTE Ltd 3 July 1970 [3 July 1969] 32358/70 Heading D1F A band of filaments e.g. uncrimped or stuffer-box crimped tow required to be crimped and/or stapled or split fibre web made from stretched oriented film and convertible into a bonded "non-woven" fabric which may be reinforced by laminating with a film or paper and/or consolidated by heating, is spread or converged by placing it transversely across and between the turns of a helix of uniform cross-section, which thereby subdivides the band into portions, and altering the distance between the turns to enlarge or narrow the width of the band. In practise, the band is deposited at an appropriate position on a track of a rotary conveyor in which the forward path of travel widens and the return path narrows. The conveyor consists of an endlessly circulating group of parallel coil springs each having a shaft passing through its centre. The springs, projecting or "wedging" into the filaments, are forced to expand or contract in a direction perpendicular to the path of the band and, when the latter has been adjusted in width, it is lifted from the conveyor. Two or more conveyors (which may be embodied in a single multi-stage machine) may be successively driven and the direction of a successively treated band therebetween changed by a bar or roller and/or a band may be spread in one conveyor and converged in another, to ensure uniformity in thickness of the adjusted band and to retain or restore a parallel array of the filaments. As shown in Fig. 1(c), a spreading or converging spring unit comprises a rigid bar 5 extending through a coil spring 6 and discs 10, 10', which anchor the ends of the spring and rotate while inclining to each other, and shaft retaining springs 8, 8', fit between the discs and collars 7, 7'. Fig. 2 shows a conveyor comprising coil springs, each surrounding an extensible and contractible rubber shaft affixed to the peripheries of inclined discs 13, 13', rotated by axles 12, 12', through universal couplings 11, 11', and effective to spread a band 14 supplied over a roller 15 and removed by a roller 16. The shaft for each spring may be solid or tubular and/or formed by sections slidable one within the other. The extension or contraction of the spring may also be effected by engagement of end attachments and converging chains, Figs. 4, 5 and 6 (not thereof with or in cam-tracks or diverging shown).

Title: Stable herbicidal compositions containing thioncarbo-methoxy disulphide and a process for the stabilization of thioncarbomethoxy disulphide
IPC: C07C329/00
Filed: 1961-09-08
Abstract: Thioncarbomethoxy disulphide (CH3O-CS-SS-CS-OCH3) is stabilized by the addition thereto of at least one acid of formula RCOOH, where R represents an alkyl group having 1 to 4 carbon atoms, in a quantity based on the disulphide not exceeding 5% by weight, 0.1-2% generally being sufficient.  The preferred stabilizers are acetic acid and propionic acid. In tests carried out in a solvent (mainly xylenes), containing a mixture of alkyl aryl sulphonate and an ester of a polyethylene glycol ether as emulsifier, the stabilizing effect of acetic acid on the disulphide was compared with the effects of dichloroacetic acid, formic acid and pyridine. The stability of the disulphide in the absence of a stabilizer was also examined; comparative tests were made on thioncarboethoxy and thioncarboisopropoxy disulphides. In another series of tests, the stabilizing effect of acetic acid was compared with that of propionic, hexoic and octoic acids. Thioncarbomethoxy disulphide was prepared by reacting methanol, carbon disulphide and sodium hydroxide to form a solution of sodium methyl xanthate which on treating with chlorine gave the desired product. The stabilized disulphide is useful as a herbicide (see Division A5).ALSO:A stable herbicidal composition comprises thioncarbomethoxy disulphide (CH3O-CS-SS-CS-OCH3) as the active ingredient and at least one acid of formula R COOH, Where R represents an alkyl group having 1 to 4 carbon atoms, as a stabilizer in an amount not exceeding 5% by weight based on the disulphide.  The composition may contain a suitable carrier such as a hydrocarbon, e.g. a xylene, and an emulsifier, e.g. a mixture of an alkyl aryl sulphonate and an ester of a polyethylene glycol ether.  The preferred stabilizers are acetic acid and propionic acid.  The composition is suitable for use as a contact-herbicide, and may be employed in combination with other herbicides, e.g. isopropyl N-(3-chlorophenyl)-carbamate.  The action of thioncarbomethoxy disulphide on garden-cress is compared with that of thioncarboethoxy and thioncarboisopropoxy disulphides.
