Title: Improvements in or relating to alkyl acrylate polymers
IPC: C08F220/12
Filed: 1950-11-22
Abstract: Thermoplastic, saturated, rubbery interpolymers are prepared by polymerizing a mixture comprising 80 to 95 per cent by weight of an alkyl acrylate, 2 to 20 per cent of a neutral, polymerizable haloalkyl vinyl compound having its vinyl group separated from the haloalkyl group by an oxygen-containing structure, and 0.1 to 5 per cent of a divinyl aryl hydrocarbon. Preferred alkyl acrylates are those containing 4 to 8 carbon atoms, and mixtures of these with one or more higher acrylates, e.g. of 8 to 14 carbon atoms, may also be used. The haloalkyl vinyl compounds are composed exclusively of carbon, hydrogen, oxygen and halogen atoms and include the haloalkyl vinyl esters of aliphatic monocarboxylic acids, the haloalkyl esters of acrylic acid and the haloalkyl vinyl ethers and ketones. Examples are vinyl chloroacetate, chloropropionate, chlorobutyrate and bromoacetate; 2-chloro- and 2-bromo-ethyl acrylate, 1,2-dichloroethyl acrylate, 3-chloropropyl acrylate, 2 - bromo - 3 - chloro - 1 - propyl acrylate, monochloroisopropyl acrylate, 4-chlorobutyl acrylate, etc.; chloromethyl-, 2-chloroethyl-, 1-bromo-1-chloroethyl-, 3-chloro-propyl-, 2,2,2-trichloroethyl- &c. vinyl ethers; 2-chloroethyl vinyl ketone, 1,2-dibromoethyl vinyl ketone, 3-chloropropyl vinyl ketone, 4-chlorobutyl vinyl ketone, &c. These compounds produce interpolymers containing side-chain halogen substitution which enables the production of strong, rubber-like cured products. The divinyl aryl hydrocarbons include p-divinyl benzene, 1,3-divinyl benzene, 1,4-divinyl-2-methyl benzene, and 1,4-, 1,5- and 1,8-divinyl naphthalenes. Polymerization may be effected in bulk or in solution using heat or actinic light with or without peroxy catalysts, but preferably in aqueous emulsion.  Emulsifying agents used include fatty acid soaps, high molal sulphates, aryl and alkaryl sulphonates and the salts of high molecular weight bases such as diethylaminoethyloleylamide hydrochloride, cetyl trimethyl ammonium methyl sulphate and lauryl amine hydrochloride. Specified catalysts are benzoyl and hydrogen peroxides, potassium, sodium and ammonium persulphates, cumene hydroperoxide and diazoamino benzene. Mercaptan modifiers may also be employed. Temperatures of from -20 DEG  to 100 DEG  C. are possible.  A buffer such as sodium pyrophosphate may be present in the emulsion from which the interpolymer may be obtained by coagulation with calcium chloride solution.  The products may be cured with conventional agents.

Abstract: 393,163. Addressing-machines. ADREMA MASCHINENBAUGES.,62, Alt Moabit, Berlin. Oct. 13, 1932. No. 28658. Convention date, Oct. 13, 1931. Addition to 377,868. [Class 100 (ii).] Tripping-arrangements.-The selector device described in the parent Specification is modified by dispensing with the mirrors and by providing a separate photo-electric cell at the position of each control signal utilized in a selection of the plates or stencils passing through the machine. As shown in one form, light from a strip-lamp c passes directly through the perforations in an address-plate a and then through light-collecting tubes 100 and on to cells n plugged into sockets 6, 61 in a switchboard 5, the sockets being connected by wires 7 whereby when the pairs of sockets not used for cells are short-circuited, the cells n are connected in series. The socket 6 at one end is connected to a battery, and the socket 61 at the opposite end is connected to an amplifier 3 such that current flows only when the plate a possesses a perforation opposite to each cell n. In a modification, the sockets 6, 6<1> are mounted in separate conductors bridged by the cells n which are therefore in parallel so that when light passes through a perforation on to any one of the cells, the control circuit is closed. In a further modification, the conductors are subdivided into pairs each corresponding to a group of signals so that the circuit is closed only when a perforation is present in each group. In another arrangement, the switch block 5 is subdivided, and the separate blocks are connected in parallel such that selection is effected only if all the cells n in at least one group are energized. The Specification as open to inspection under Sect. 91 comprises also an arrangement wherein each one of a number of cells arranged in series corresponds to ten signal perforations in the address-plate or in a control card, and a mirror is arranged above certain selection positions at the control point whereby light from a lamp is reflected on to the cells. A mirror is provided for each signal position, those not in use being removed or turned into inoperative positions. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,108,568. Fluid pressure operated brakes. GIRLING Ltd. 30 June, 1965 [14 July, 1964], No. 28931/64. Heading F2F. In a booster and. auxiliary master cylinder unit for an hydraulic braking system of the kind in which a piston 24 in the auxiliary master cylinder 21 is actuated by the booster, the energization of which is controlled through valves carried by a T-shaped rocking lever 28 which is engaged by a differential control piston 29 acted upon at one end by hydraulic pressure from a pedal-operated master cylinder and at the other end by hydraulic pressure generated in the auxiliary master cylinder, an axial passage 34 in the control piston 29 is closed by a valve 35 when the control piston moves away from a stationary abutment 39. As shown fluid pressure from a pedal operated tandem master cylinder is connected to a port 33 of the auxiliary master cylinder. Prior to operation of the brakes, the control piston 29 is urged leftwards by a spring 38 so that the valve 35 is open and fluid from the tandem master cylinder may pass through the control piston directly to the slave cylinders of the brakes. When fluid is supplied to the inlet 33, the hydraulic pressure moves the control piston 29 rightwards, closing the valve 35 and actuating the rocking lever 28, which forms part of a valve assembly of the type disclosed in Specification 786,524, to operate the booster and generate pressure in the pressure space 21 of the auxiliary master cylinder. This pressure is communicated to the store cylinders of the brakes and also acts on the small end of the differential piston 29 in opposition to the force exerted by the pressure on the large end of the control piston. In a braking system using the booster (Fig. 1, not shown) the front wheel brakes are operated by pressure from the booster and the rear wheel brake, which have store cylinders (13) larger in diameter than the front wheel brake cylinders 18, are operated directly from the master cylinder 10. A spring-loaded valve 42 may be inserted in the line 17 from the booster to prevent the front wheel brakes being actuated until a predetermined pressure is reached.
