Title: Means for temporarily charging and automatically discharging air pressure chambers
IPC: B61H7/08
Filed: 1933-10-10
Abstract: 409,209. Valves; brakes; drophammers. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, Berlin. Oct. 10, 1933, No. 27934. Convention date, Nov. 3, 1932. [Class 135.] A piston-actuated valve automatically vents chambers required to be under air-pressure only temporarily. As applied to electromagnetic rail-brakes for vehicles, a lifting-cylinder lifts the brake magnets and is then vented, the magnets being held above the rail during the unbraked travelling by a known locking-device. The invention is also applicable to drop hammers in which the ram is lifted by compressed air. In Fig. 1, compressed air at b by means of a piston c moves a slide-valve d, and passing through a constriction g reaches the cylinders l which are to be temporarily charged. Thereupon the spring e reverses the piston and valve, and the cylinders are vented at o. In Fig. 2 the air at b is led in between the heads c, k of a differential piston, and also to a known pressureregulator i with adjustable spring. The piston and valve move to the right, the air charging chamber l by pipe f. The back pressure then actuates the regulator i to allow compressed air to reach piston c through pipe h, moving the valve to the left and venting the chamber l at o.

Title: Preparation of beta-mercaptopropionitrile
Filed: 1966-06-22
Abstract: Beta-mercaptropropionitrile is prepared by reacting acrylonitrile with liquid hydrogen sulphide in the presence of an organic base as catalyst.  Suitable bases are aliphatic amines such as di- or triethylamine; diamines such as tetramethylene diamine; piperidine and quaternary ammonium bases such as trimethyl benzyl ammonium hydroxide.  Preferably, 5-15 moles of H2S per mole of acrylonitrile are used in the reaction, which is suitably carried out at - 10 DEG to 50 DEG  C. under 5-25 atm. pressure.  The reaction may be carried out in a hydrocarbon solvent such as benzene or toluene or in an alcohol such as ethanol.  After the reaction, the excess H2S can be removed by evaporation and the catalyst deactivated by acidification, but it is preferable to acidify before removal of the H\2S to prevent polymerization of the product.

Abstract: 343,990. Sound reproduction in association with Kinematographs. BLUM, C. R., 54, Badenschestrasse, Sch÷neberg, Berlin. Sept. 21, 1929, No. 28698. [Class 97 (i).] Sounds transmitted by line or wireless are reproduced in synchronism with projected pictures at one or more receiving stations by the aid of rhythm bands carrying notes, words or the like arranged along the band to correspond with the sounds, a band being provided at the transmitting station and at each receiving station, the band at the transmitting station being driven at a suitable speed in conjunction, if desired, with the projection of a picture film to serve as a guide to the conductor or the artists producing the sounds and those at the receiving stations, which are driven in synchronism with the picture projectors, being controlled so that the notes &c. thereon pass under a fixed index in correspondence with the sounds reproduced in the loud speakers. The production of suitable rhythm bands is described in Specifications 341,844, and 345,278. As shown, the sounds are produced at the transmitting station by instrumentalists, vocalists or gramophone records under the guidance of one or more rhythm bands 1 which travel below a fixed index and are driven in synchronism with a projector 5, 6, 7. These sounds are picked up by a microphone 12 and transmitted by wireless for reproduction by loud-speakers 19 at the receiving stations in which similar rhythm bands 1 are driven below fixed index marks in synchronism with picture projectors 20, 6 so that the notes &c. passing the index marks correspond with the picture projected. Correct synchronism with the reproduced sounds is maintained by controlling the bands 1 so that the notes corresponding thereto pass under the marks when the sounds are heard. A suitable synchronous drive from the projector to the band is described in Specification 339,941, [Class 40 (i), Electric signalling systems &c.], control being affected through contacts 8, 21 engaging the picture films. The bands may carry marks corresponding to periodic signals from the transmitting station to facilitate starting up the apparatus, and may also carry time indication marks to facilitate starting in at any time and also numbers corresponding to numbers on the picture film for resetting after a breakage. Clocks may be arranged to start the apparatus at the receiving stations automatically.

Solid water-soluble cationic polymers are prepared by polymerizing in aqueoussolution at least one monomer of Formula I wherein R is H or C 1 -C 4  alkyl, X is -O- or -NH-, A is C 2 -C 8  alkylene (straight chain or branched), R 1 , R 2  and R 3  which may be the same or different are C 1 -C 4  alkyl, benzyl, hydroxyalkyl or carbamoylmethyl, and Y<SP>n-</SP> represents the anion of an acid (e.g. chloride, sulphate, acetate, methosulphate or p-toluenesulphonate), n being the valency of the anion, optionally with a minor proportion (based on the total weight of monomers) of at least one comonomer; the resulting solution being thereafter evaporated to a polymer content of at least 85% by weight. The aqueous polymerization medium may, if desired, include a watermiscible solvent such as acetone. Suitable comonomers that can be used include watersoluble monomers such as acrylamide, methacrylamide, N-vinylpyrrolidone or acrylonitrile, and water-insoluble monomers such as C 1 -C 4  alcohol esters of acrylic or methacrylic acid, vinyl acetate or styrene. Polymerization can be effected with initiators such as α,α<SP>1</SP>-azodiisobutyramidine dihydrochloride, 4,41-azobis- 4,4<SP>1</SP>-dicyanovaleric acid and redox systems, e.g. ammonium peroxydisulphate/sodium pyrosulphite, hydrogen peroxide/ferrous salts and persulphate / sodium hydroxymethane-sulphinate. The addition of a metal ion complexing agent, e.g. sodium ethylene diamine-tetraacetate or sodium phosphate, is advantageous. The polymerization vessel used preferably has flexible walls; this facilitates removal of the polymer product from the vessel. Such vessels may be formed from a synthetic resin such as polyethylene or polypropylene. Alternatively the vessel may be in the form of a rigid plate with high-flanged edges, a flat tray or a trough, the interior surface thereof being at least partially covered with a flexible metal, plastics or treated paper foil. The polymer products are useful as flocculants, retention agents in paper manufacture, thickening agents, and antistatic agents.
