Title: Copolymeric plasticisers for vinyl chloride polymers
Inventor: MARPLES BRIAN ARTHUR
IPC: C08L9/00
Filed: 1963-07-11
Abstract: Novel copolymers having an average molecular weight of from 300-1500 comprise units of a conjugated diolefin having 4 to 6 carbon atoms, an isoalkene of 4 to 8 carbon atoms and acrylonitrile or an alpha-substituted derivative thereof, the proportion of nitrile being at most 40% by weight of the copolymer.  Suitable diolefins include piperylene, isoprene, 2,3-dimethylbutadiene and butadiene. Isoalkenes specified are isobutene and 3-methylbutene-1, and methacrylonitrile is an example of a suitable acrylonitrile derivative.  The copolymers may be prepared by polymerizing the appropriate monomers in solution in an inert solvent, e.g. toluene or cumene, using a peroxide initiator, e.g. di-t-butyl peroxide or cumene hydroperoxide, and a chain transfer agent such as ethyl or isopropyl mercaptan or hydrogen sulphide. When such sulphur-containing agents are used, the polymer products may be treated with an adsorbent such as activated alumina or charcoal to remove odours and discoloration. The mobile copolymer products are suitable as plasticizers for polymers comprising at least 90% by weight of vinyl chloride units, e.g. polyvinyl chloride and vinyl chloride-vinyl acetate copolymers.  In examples, white lead and calcium stearate are included in the plasticized compositions.

Abstract: 907,415. Turnstiles. BRECKNELL, DOLMAN & ROGERS Ltd., and DOLMAN, H. J. Aug. 12, 1960 [Aug. 12, 1959], No. 27559/59. Class 106(3). A turnstile comprises a turntable 1 on which persons are carried through a barrier 12, 12A. The turntable is driven by an electric motor 6 through chain and worm gearing, and continues to run as long as a coin is inserted at 13 for each turnstile compartment which is about to pass the barrier. Absence of a coin leads to the switching off of the motor and its arrest by a solenoid-controlled brake. A plurality of coinreceiving boxes 13, one associated with each compartment, may move with the turnstile, inserted coins dropping through when a fixed, common till is reached. Provision is made for accepting and checking a fee consisting of two similar or dissimilar coins. The barrier 12, 12A is arranged to yield slightly in the direction of movement of the turnstile, and thus operate a cut-out switch for the motor if a person becomes trapped.

Title: Improvements in epicyclic variable speed gearing
IPC: F16H61/02
Filed: 1934-09-28
Abstract: 444,899. Variable - speed gearing. THORNTON, A. A., 7, Essex Street, Strand, London.-(Cotal, J.; 5, Rue Poyer, Clichy, Seine, France) Sept. 28, 1934, No. 27841. [Class 80 (ii)] Comprises a variable-speed gear with two direct-driving and reducing electromagnetically controlled epicyclic trains P, Q, each having a sun gear, planets, and an annulus, in which the two rotary or clutching elcctromagnets A, D of the two trains P, Q, respectively, are on the outside fast on driving and driven shafts E, F, respectively, and the two corresponding stationary or braking electromagnets B, C are between the rotary electromagnets. The arrangement shown in Fig. 1 yields four forward speeds, and there is a simple mechanical sliding reversing- train O interposed between a first-motion shaft N and the driving hollow shaft E of the variable gearing. A loose carrier K carries the stepped planets K<1> of the train P and the annulus L of the train Q. The sun 6 of the train P drives and the annulus H carries an armature G common to the clutch A and the brake B. The planets M<1> of the train Q are on a carrier M fast on the driven shaft F, and the sun J carries an armature I common to the clutch D and brake C. For first speed, both trains reduce. For second and third, the trains reduce separately. Fourth speed is solid on both trains. At V is shown a spring dog adapted to be turned manually and lowered to engage a recess X in the driven electromagnet D so as to lock, say, the driven shaft of a vehicle against rotation. A pump is shown at 4 which pumps lubricating oil into a central conduit of the central shafts. This pump is identical with that described with reference to Fig. 3, of Specification 272,532, [Class 80 (ii)]. An arrangement is described in which the first-motion shaft N and the driven shaft F project from the same side of the gearbox, the latter being a sleeve upon the former. In an embodiment shown in Fig. 2, the first train P reverses as well as reduces when. the armature G is braked. This gearbox thus yields two forward speeds only, the direct and reduced speed of the train Q, each being reversible through the train P. Specification 332,789, [Class 80 (ii)], is referred to.
