Abstract: Aliphatic mono-olefines having up to 8 carbon atoms per molecule such as ethylene, propylene, 1-butene, 2-butene, 1-octene, 2-octene, diisobutylene, and trimethyl ethylene, are copolymerized with aliphatic mono-olefines having 8 to 20 carbon atoms per molecule, such as tetradecene, hexadecene, octadecene, and tetraisobutylene, and cracked wax, olefines obtained from the Fischer-Tropsch process, dehydrochlorinated chlorinated wax, polyethylene and polypropylene, containing from 8 to 20 carbon atoms per molecule, at a temperature below 0 DEG  C. in the presence of a Friedel-Crafts catalyst such as aluminium chloride. Terpolymers may be prepared by including styrene in the monomer mixture.  Copolymerization may be carried out by dissolving the monomers in an inert solvent, such as methyl chloride, and adding the catalyst, or by adding the catalyst, preferably dissolved in an inert solvent, to one of the monomers to form a catalyst-olefine complex, and then adding the other monomer to the complex.  Further catalyst or monomer may be added during the course of the reaction, which may be carried out as a continuous process. The copolymers are viscous, oily liquids which are used, optionally in conjunction with chlorowax-naphthalene pour-point depressants, as additives to lubricating oils.  The Specification as open to inspection under Sect. 91 includes the use of olefines other than aliphatic mono-olefines, such as styrene and butadiene, in the preparation of the copolymers.

Title: Improvements in or relating to the manufacture of chlorinated rubber
IPC: C08C19/14
Filed: 1934-10-23
Abstract: A continuous process for the chlorination of rubber consists in reducing the viscosity of a rubber solution to less than 4 poises, preferably 0,2-1 poise, and passing this solution in counter current to a stream of chlorine gas.  A 4-4,5 per cent solution of rubber, obtained, e.g. by premastication of the rubber, or by irradiation is fed to the top of a lead-lined tower which is maintained full of the solution, the supply being controlled either at the inlet or outlet. When carbon tetrachloride is the solvent employed, the process is preferably worked at a temperature of 50-75 DEG  C. Chlorine, pure or diluted, is fed through nozzles in the bottom of the tower, the amount being regulated so that there is about 2,8 parts by weight of chlorine, to 1 of rubber.  The chlorine is preferably saturated with the rubber solvent before admission to the tower.  On issuing from the tower, the chlorine dissolved in the chlorinated solution may be utilized for reducing the viscosity, as described in Specification 424,061, or it may be removed by boiling, air blowing, or the like. Specification 422,192 also is referred to.

Abstract: 504,839. Mechanical presses. BOBST ET FILS SOC. ANOX., J. Nov. 5, 1937, No. 30430. Convention date, Nov. 18, 1936. [Class 87 (ii)] [Also in Group VIII] A press, more particularly for cutting-out cardboard from a web, is driven by means including a two-speed device. In one form, the fly-wheel 19 carries planet wheels 23, 22 meshing with gears on a brake drum 24 and a sleeve 20 slidably keyed to a shaft 7. When a band 25 is tightened on the drum by an electromagnet 31, the shaft 7 is driven at low speed. When a cone 28 is moved in by means of a lever 32 to expand frictional members 26 into engagement with the fly-wheel, the shaft 7 is driven at high speed. Movement of a rod 33 by the lever 32 breaks contacts 36 to prevent energization of the electromagnet 31 while the machine is running at high speed. To prevent the machine stopping while the head 2 is in its lowest position, the .latter carries a contact piece 37 which engages contacts 38 at this position and maintains the circuit through the electromagnet 31 if the machine is not running at high speed. The head 2 can be moved to inoperative position by a lever 13, eccentric 14, link 15, arm 16 and eccentrics 17 ; the contact piece 37 is simultaneously moved. The machine may be operated at low speed by closing switches variously situated. The Specification as open to inspection under Sect. 91 comprises also a two-speed gear comprising a double-cone which is engaged to drive the shaft 7 either directly at high speed or through gears at low speed.
