Abstract: In copolymerizing an a ,b -unsaturated dicarboxylic acid semi-ester with an ethylenically unsaturated organic compound in bulk or concentrated solution using a free radical-forming catalyst, the organic compound and the catalyst are gradually added to the semi-ester.  The semi-ester may be derived from maleic or fumaric acid and methyl, ethyl, butyl, dodecyl, cyclohexyl, octadecyl or benzyl alcohol.  Specified unsaturated organic compounds are styrene, a -methyl styrene, nuclear substituted styrenes; vinyl acetate, butyrate and stearate; methyl, ethyl, butyl and dodecyl esters of acrylic and methacrylic acids; dialkyl esters of fumaric acid; and methyl, ethyl and isobutyl vinyl ethers.  The catalyst may be benzoyl peroxide, a peracid, azodiisobutyric acid dinitrile or a sulphinic acid or derivative thereof.  Redox systems of a per-compound with a reducing agent, e.g. an amine, sulphinic acid or mercaptan, may also be used in which case the reducing agent is present in the semi-ester.  The solvent may be benzine, benzene, toluene, xylene, dioxane, chlorobenzene, ethyl and butyl acetates, acetone and methyl ethyl ketone.  The products are of high molecular weight, are soluble in most solvents and are useful as emulsifiers, impregnating agents and as lacquer additives.

To ensure proper operation of a ring counter, e.g. in a railway signalling system, even though one of the stages fails, each stage is prepared for operation by two of the preceding stages. In Fig. 1 stepping pulses are applied alternately to leads S1 S2. Operation of either stage A or stage B restores stage C so that the next stepping pulse on lead S1 reoperates C. Failure of either A or B then has no effect on the proper operation of C. In Fig. 2; stepping pulses are applied in turn to leads S1-S4 to operate stages AD. Stage E is controlled by A and B, C and D in pairs and failure of any one of A-D either to operate or release has no ill effect on E. A pulse applied over lead RL either to all the stages or only to the first four restores all stages. Fig. 3 shows the invention applied to the disclosure in Specification 901,886 in which an auxiliary transistor TR3C controlled by the preceding stage B is augmented by another transistor TR4C controlled by the next preceding stage A. To ensure that the stepping pulse on lead S1 which operates stage A shall not also operate stage C, the control lead between the stages includes a capacity delay RCA2.
