Title: Railway control signal dynamic input interlocking systems.
IPC: B61L19/06
Filed: 1979-05-30
Abstract: The specification discloses an electronic or computer-based railway control signal interlocking system. Signals representing the settings or conditions of railway control elements e.g. track circuits, signals and points, and their control signals are checked as usual by the interlock equipment to establish route safety. However failures in the system may only be discovered when a change to a control element setting is attempted. Since long periods can elapse between changes a failure may lie dormant for some time. In order to reduce dormant wrong side failure periods to a minimum the signals supplied to the interlocking equipment are periodically switched to a predetermined state chosen to prove that when the interlocking equipment receives the switched signal that a wrong side failure mode does not exist in the switched signal path.

Title: Emulsion polymerization process for producing vinyl dispersion resins.
IPC: C08F/
Filed: 1980-12-19
Abstract: New and novel process of producing a vinyl resin latex by the emulsion polymerization technique comprising adding to the latex with thorough mixing, an aqueous solution of an electrolyte, such as, for example, ammonium carbonate, and removing a part of the water by filtration or centrifuging, and the like, to produce friable aggregates of individual spheres of polymer particles. Thereafter, the friable aggregates of polymer particles are separated into individual spheres of polymer particles by simple light rubbing or crushing and dried. In many cases, the separation can be accomplished by simple mixing of the resin with plasticizer during the plastisol preparation. Thus the spray drying and the subsequent grinding steps are eliminated producing a superior product for plastisols.
