Abstract:
A method for continuously coagulating a rubbery polymer latex to obtain a polymer solid, characterized in that into a coagulator composed of (a) a cylindrical body having at one end a nozzle for feeding rubbery polymer latex and a nozzle for feeding coagulant solution, and having at the other end a discharging nozzle, (b) a stirrer mounted rotatably along the central axis of the cylindrical body, said stirrer having several stages of agitating blades, and (c) stationary blades fixed to the wall of the cylindrical body at the spaces between the stages of agitating blades, are continuously fed the rubbery polymer latex and a coagulant solution through the above-mentioned respective nozzles so as to collide against each other, and stirred during their movement from the one end of the coagulator to the other end to coagulate the latex. By this method, there can be obtained molded porous polymer crumbs having an intended size.
Abstract:
A machine for splicing unvulcanized inner tubes. The machine employs a clamp which is adjustable for holding various size inner tubes. The clamp has a pair of end sections with configured recesses for receiving opposing edges of the inner tube and a pair of intermediate sections which are removably positionable in abutting relation between the end sections. Means are provided for varying the spacing between the end sections to accommodate different intermediate sections.
