Abstract: 170,074. Veulle, F. H. de. July 8, 1920. Roses; air-pressure sprayers; sprayer formed by wires wound across grooves. -A spray-producer more particularly for carburettors comprises a body A provided with one or more narrow grooves A<2> in its surface which communicate with a conduit A<4> for the liquid and are crossed throughout their length by one or more strips of wire B preferably in the form of a continuous helix. For this purpose, the body A has formed on it a helical groove of V or similar section in which is wound the wire B, the diameter of which is slightly less than the pitch of the helix. Fig. 3 shows a form of carburettor in which the bodv A is conical, surrounded by a choke tube C<4>, and mounted in a carburettor body the inlet of which is at C<2> and the outlet to the engine at C<3>. The sprayer may be provided with air passages A<6>, A<7>, A<8> leading to grooves A<9> distinct from the grooves A<2> to break up the liquid more completely. Fig. 4 shows a form of carburettor in which the sprayer body A is cylindrical and is also fitted if desired with air passages as shown in Fig. 3. In Figs. 5 and 6, a cylindrical sprayer is shown mounted to one side of an air-conduit D<2> of a carburettor, its upper and lower ends being mounted in sockets D<3> extending from the main conduit. Fuel is led into the lower socket D<3> and air into the upper socket D<3>, whence it passes through the passage A', A' to longitudinal grooves A<7>. A lateral branch D<4> is provided for a throttle valve (not shown).

Apparatus for cutting facsimile recorder paper 22 fed by rollers 9, 10 along a guideway 20 comprises a rotatable cutter wheel 45 spring-urged against the edge 26 of a fixed cutter 25, the cutter wheel being mounted on a carriage 30 spring-loaded by a guide 16 and the carriage carrying a pinion 35 engaging a rack 17 and geared to the cutter wheel, the carriage also carrying a member 51 having a fitting 54 secured to the ends of a chain 55 passing over sprockets 56, 57, the sprocket 57 being driven by a reversible motor 60 and the arrangement being such that when the motor is started by a signal from the recorder the carriage is moved along the rack and at the same time the cutter wheel is rotated to cut the paper. As the carriage reaches the end of its travel it contacts an operating arm 64, or 65 of a limit switch 61, or 62, thereby stopping the motor. As the paper passes the cutting edge 26 it becomes subject to an air flow initiated by a motordriven fan 71 and is thereby urged upwardly in a tray 3 so as to prevent jamming thereof. The guide 16 is engaged by a bearing 52. In a modification, Figs. 6 and 7 (not shown), the apparatus is provided with a pair of rollers beyond the cutters for delivering the cut paper in a tensioned condition to the tray through which an air flow passes.

Abstract: Factice is prepared by heating with sulphur, and optionally with a catalyst, an unsaturated saponifiable oil of iodine value above 140, which has been pretreated by reacting in a heated state with liquid or vaporized styrene monomer.  The oil may be pretreated by passing styrene vapour carried by an inert gas through the heated oil or by adding liquid styrene gradually to the agitated and heated oil.  In examples, (1) alkali-refined linseed oil (I.V. 180), heated to 280 DEG  C., is treated with styrene vapour and the product is heated to gelation at 160 DEG  C. with powdered sulphur; (2) and (3) cold-filtered cod oil (I.V. 165), heated to 280 DEG  C., is agitated and styrene monomer is dropped in over a period; the product is heated with sulphur and dicyclohexylamine.  Specification 588,353 is referred to.ALSO:Factice is prepared by heating sulphur and optionally a catalyst with unsaturated saponifiable oil of iodine value above 140, which has been pre-treated by reacting in a heated state with liquid or vaporized styrene monomer.

Abstract: 148,407. Bielmann, O., and Bielmann, C. March 14, 1919, [Convention date]. Addition to 147,838. Fruit syrups.-In the manufacture of fruit juice or jelly with simultaneous production of marmalade or conserve by circulating sugar solution in counter-current through vessels containing fruit and like vegetable products, as described in the parent Specification, the extraction process and production of conserve are carried out in a single vessel the temperature in which increases from above downwards. In the apparatus shown, the sugar solution is produced in a vessel 3 provided with stirrers and heating pipes, whence it passes into a vessel 1 into which the fruit &c. are also introduced. The fruit and sugar solution are forced under pressure up a pipe 5 into a straining hopper 6, whence the solution passes into a tank 9 and the fruit into the extracting vessel 8, which is jacketed and heated by steam. From the tank 9 the solution passes to distributors 19 arranged about one-third of the way up the vessel 8. an overflow pipe 11 leading from the tank 9 to the vessel 3 being also provided. The solution passes up through the vessel 9 and is drawn off at 20 charged with the flavour &c. of the fruit. The working of the apparatus may be arranged so that the liquid drawn off at 20 remains a syrup or becomes a jelly on cooling, as desired. Owing to the pressure of the column of fruit and syrup, a higher temperature is attained at the bottom of the vessel 8 than at the top, so that the fruit &c. at the bottom of the vessel is disintegrated and can be drawn off to form a conserve through strainers 23 provided with domeshaped covers 25, into which steam &c. can be introduced to clear the strainers. Pips, stalks, &c. that will not pass through the strainers are withdrawn through pipes 26.

Abstract: 1341283 HVDC power transmission ALLMANNA SVENSKA ELEKTRISKA AB 19 April 1971 [27 Jan 1970] 20399/71 Heading H2F In an HVDC converter station having at least two parallel converters each having devices to limit their control angles, connections are provided for balancing current distribution between the two converters when the limit value device for at least one converter becomes active and including means for supplying signals which influence the control system of the other converter in the event of a difference occurring between an operating magnitude in the two converters. As shown, a pair of inverters 60, 70 are fed in parallel from a HVDC line supplied by a pair of parallel-connected rectifiers (not shown) and controlled by pulse generators 61, 71 in dependence on the difference between line current (measured at 65, 75) and desired current (inserted at 8). Margin angle control devices 68, 78 are included. When one control device 68, 78 senses a low margin angle, it emits a pulse to both inverters 60, 70 so that they both commutate together and tend to equalize their currents. Alternatively the current difference may be detected at 67 and fed via polarity-discriminating diodes 66, 76 to the margin angle control device 68, 78 of the appropriate inverter 60, 70. In this case, AND gates must replace the OR gates 69, 79. Phase shifters 64, 74 may be included to compensate for differing phase angles in the two inverters 60, 70.
