Title: Improvements in and relating to processes for treating rubber
IPC: C08C19/12
Filed: 1934-05-08
Abstract: Organic hypochlorites are made by preparing a solution of hypochlorous acid by any usual method, shaking this solution with half its volume of an inert solvent (benzene, xylene, carbon tetrachloride) containing 10--15 per cent by volume of alcohol, and rapidly drying the solvent layer by shaking with a drying agent, e.g. calcium chloride.  According to examples: (1) chlorine is passed into ice-cooled suspension of calcium carbonate; (2) caustic soda is added to an aqueous solution of mercuric chloride, chlorine is passed in and nitric acid then added slowly; (3) nitric acid is run on to cooled bleaching powder and the turbid solution is filtered; (4) chlorine monoxide is run into cooled carbon tetrachloride; in each case treatment with alcohol as above follows.  Other alcohols mentioned are methyl alcohol, higher aliphatic alcohols, dihydric and polyhydric alcohols, chlorohydrins, aralkyl and hydroaromatic alcohols.  The solution is used for treating rubber in solution to obtain a substance having most of the properties of chlorinated rubber.ALSO:Organic hypochlorites are added to rubber in solution to obtain a product having some of the resilience of rubber, and also many of the properties of chlorinated rubber, such as low viscosity of solutions and chemical inertness.  The product is soluble in ordinary solvents until the solvent has been removed, when it becomes insoluble.  Methyl or ethyl hypochlorite are preferred due to their greater safety in handling; for the same reason, it is preferred not to isolate them from the solution in which they are prepared.  The product contains about 30 per cent. of chlorine, and consists mainly of addition products.  The process comprises: (1) preparation of a dilute solution of hypochlorous acid by any usual method, (2) shaking this solution with half its volume of an inert solvent (benzene, xylene, carbon tetrachloride) containing 10-15 per cent of alcohol, drying the solvent layer, e.g. with calcium chloride, and adding to a rubber solution, (3) concentrating the solution after at least 24 hours, under reduced pressure at a temperature preferably not exceeding 40 DEG  C.  Stages 1 and 2 may be combined.  Several examples are given, of which the following is typical: 1890 grams of cold 5 per cent nitric acid are run on to 190 grams of cooled bleaching powder; the solution is filtered and shaken with 1000 cc. of benzene containing 100 cc of alcohol; the solvent layer is removed, dried with calcium chloride, and added to 300 gm. of a 10 per cent rubber solution.

Title: Improvements in and relating to hydraulic brakes
IPC: B60T11/224
Filed: 1935-05-15
Abstract: 442,341. Hydraulic brakes. BELENKIJ, J., 2, Pod Lipami c, Olomouc, Czecho Slovakia. May 15, 1935, No. 14217. Convention date, May 23, 1934. [Class 103 (i)] In a hydraulic brake both during the application and release stroke liquid is delivered into the brake pipe lines 5 leading to the vehicle brake cylinders. On brake application the differential piston 2 is moved by the brake pedal 14 to force liquid into the pipe 5 from the space 10, and liquid is drawn from a reservoir 8 through a valve 24, into the space 7. On release movement of the piston 2 to the right liquid is forced from the space 7 past a ball valve 11 into the space 10 and the pipe 5 and also past a ball valve 18 arranged in the valve 24, into the reservoir 8. The valve 18 opens at a higher pressure than the valve 11 so that a slight residual pressure is retained in the pipe line 5. Final release of excess fluid takes place past the piston 2 in the release position through passages 22, 23 and through a porous material 25 the object of vehicle is to slow down passage of the liquid on brake application. Restricted passage 0 allows final escape of liquid into the reservoir 8. A modification comprises differential pistons in coaxial cylinders.

Title: Improvements in or relating to punching presses
IPC: B21D55/00
Filed: 1961-04-20
Abstract: 950,512. Punching. INFRANOR S.A. April 20, 1961 [April 21, 1960], No. 14303/61. Heading B3W. In a punching press for making washers from a metal band and comprising a matrix 5, a punch 6 and at least one extractor 9 slidable during punching in either the matrix or the punch against the force of a spring 15, the position of the extractor relative to the matrix or the punch is indicated by means of a device constituted by spaced, coaxial electrical windings 19, 20 connected to the matrix or punch and axially traversed by a magnetic core 14 connected to the extractor so that relative displacement between the extractor and the matrix or punch provides a corresponding displacement between the core and the windings, the device incorporating an electric circuit which is sensitive to the modification of the value of the inductance of the windings as a function of the position of the magnetic core. The matrix 5 mounted in a socket 1 is surrounded by an annular part 11 supported by springs 12 and is formed with a part conical bore 8. The punch 6 is fixed to a block 4 slidable on columns 2, 3 and has a central rod 8 and a recess 7 into which the extractor 9 slides. The spring 13 bears against a part 17 screwed in the block 4 and in which the windings 19, 20 are mounted. In the inoperative position of the punch the core 14 is symmetrical to the windings 19, 20. On the downstroke of the punch a washer punched out of the metal band placed on the matrix 5 is displaced in the recess 7 from which it is dislodged on the upstroke by the extractor which returns to its normal position under the action of the spring 15. If the washer is stuck in the recess 7, the extractor does not return to its normal position and the core 14 is unsymmetrically displaced relative to the windings 19, 20. The windings may constitute two branches of a Wheatstone bridge supplied with alternating current which is balanced when the core 14 occupies its median position between the windings. Spacing of the core relatively to this median position puts the bridge out of balance whence its outlet voltage is used for actuating a stop mechanism of the press or an alarm device. Alternatively, the windings 19, 20 constitute the windings of a transformer having the same number of turns and the difference in the induced voltage in the secondary winding when the core 14 is in its unsymmetrical position is used to control the stopping of the press.
