Abstract

227,968. Demmler, H. L. Nov. 27, 1923. Oscillating disc valves for manually controlling supply of pressure fluid and exhaust from pipes 72 leading to parts of a foundry moulding machine, have a supply port 71 to the chest and a transverse part 74 in the disc. The pipe 72 is exhausted at 75 through an arcuate channel in the disc. Specification 228,070, [Class 83 (i), Casting &c. metals], is referred to.
