Abstract

433,018. Moulding solid carbon dioxide by stationary-mould machines. SCHUTZ, G. A., [Firm of], 38, Dresdenerstrasse, Wurzen, Germany. Nov. 13, 1934, Nos. 32681 and 32682. Convention dates, Nov. 13, 1933 and May 25, 1934. [Class 87 (ii)] A press cylinder 7 for solid carbon dioxide is raised and lowered by fluid pressure acting on its annular base portion 7<a>, and its piston is actuated by fluid pressure acting on a connected piston 10 surrounded by the cylinder containing the base portion 7a. The press cylinder when in its top position is closed by a housing 3 containing a snow. forming chamber 1 put intc and out of communicatior with the press chamber by a fluid-actuated shutter 4 In a modification, two shut ters are provided forming between them a chamber which is intermittently filled completely with snow formed in the chamber 1 above and delivering this measured quantity to the press. The press cylinder is supported by heat-insulating rods from a base member carried by the fluidactuated annular piston 7<a>. The parts are operated cyclically by liquid pressure controlled by a valve.
