Patent GB-289500-A (GB)
Abstract: 289,500. Hocken, B. Nov. 30, 1926. Totalizators.-Summations particularly those of wagers in a totalizator apparatus may be effected and the totals indicated hydraulically by means of liquid in tubes. Fig. 1 shows a portion of an indicator at one station, there being for each horse an open liquid level gauge tube such as H and alongside it another tube T for showing the grand total of wagers laid. The amounts laid are entered by means of displacement plungers F, G lowered by screws O, and the various tubes are connected with corresponding tubes at the other stations by pipe lines L, M. In cases where stations are at different levels a mercury column, as shown in Fig. 4, may be connected with the two levels by pipes b, c to compensate for variation in the head of liquid between the levels. The displacements of liquid may be effected by pistons working in cylinders communicating with a closed pipe system. In the case of stations at different levels there may be a set of four connected rams, one for each horse and for the total at each of the levels. The apparatus may be coin-freed and according to the Provisional Specification means for intercepting proportions of liquid on account of tax may be provided.

Title: Anion exchange resins
Inventor: TSUNODA YOSHIO
IPC: C08F8/32
Filed: 1954-10-07
Abstract: A solid unfractured anion-exchange resin having at least two dimensions each in excess of one cm., comprises a three-dimensional crosslinked polymer matrix bonded with anionexchange groups, the matrix being formed by polymerization of a solution mixture of (1) at least one monovinyl aryl compound; (2) a polymic product prepared by the polymerization of (1) in an amount of at least 0.1 per cent based on (1); and (3) at least one polyvinylaryl and/or polyolefinic compound, said anion-exchange groups being formed on the matrix of haloalkylating the matrix in such an amount that there exists an average of from 0.2 to 1.2 haloalkyl groups per aromatic nucleus and then aminating said haloalkylated matrix with at least one primary, secondary or tertiary amine in such an amount that there exists in the reaction mixture at least one mol. of amine for each haloalkyl group in the matrix.  Specified monovinyl aryl compounds are styrene, vinyltoluene, ar-methyl or ar-dimethyl styrene, ar-ethylvinylstyrene, ar-chlorostyrene, ar-sec.-butylstyrene, ar-trimethylstyrene, vinylnaphthalene, ar - methylvinylnaphthalene, alpha - methylstyrene, vinylchlorobenzene and/or vinylxylene, while specified polyvinylaryl and polyolefinic compounds are divinylbenzene, -toluene, -naphthalene, -xylene- and -chlorobenzene, and ar-divinylethylbenzene, butadiene, isoprene, diallyl, dimethallyl, diethallyl, divinylether, and cyclopentadiene.  The matrix may be prepared by partially polymerizing the monovinyl aryl compound until from 0.1 to 60 per cent is converted into polymer, followed by mixing the solution with the polyvinyl aryl and/or polyolefinic compound and polymerizing before haloalkylating and aminating. The matrix may be formed as a block and then cut into a sheet before chloroalkylation; the matrix may be prepared by polymerization of the solution mixture in a vessel having two facing walls of large surface area with a small clearance.  A plasticizer may be added with the monomer or with the polyvinylaryl and/or polyolefinic compound, while a reinforcing material may also be present.  The haloalkylation may be carried out by reacting the polymer with a mixture of an aldehyde and hydrochloric acid or with a mixture of a dihalide and a Friedel-Crafts catalyst, or most preferably with chloromethyl or bromoethyl ether in the presence of zinc chloride, zinc oxide, stannic chloride, aluminium chloride, tin, zinc or iron.  The reaction is carried out while the polymer is swollen by an organic solvent such as tetrachloroethylene, chlorobenzene, or an excess of haloalkylating agent.  The amination may be preceded by swetting in a solvent such as benzene, toluene, ethylene dichloride, trichloroethane, and tetrachloroethylene, and may take place by reacting the polymer with an anhydrous amine in an organic solvent at room or higher temperatures.  U.S.A. Specifications 2,519,574, 2,592,440, 2,597,439, 2,614,009 and 2,616,877 are referred to.
