Title: Improvements in compressor plants
Inventor: AKERMAN IWAN ERNST ROLAND
IPC: F04B39/16
Filed: 1966-10-04
Abstract: 1,110,188. Compressor plant. ATLAS COPCO AKTIEBOLAG. Oct.4, 1966, No.44217/66. Heading F1N. In a compressor plant having a compressor 1 provided with a delivery chamber connected by a conduit 11 to the admission chamber 13 of an aftercooler 14, the cross-sectional area of the conduit 11 is small compared with the delivery capacity of the compressor whereby the increased gas speed therein prevents liquid being deposited on the walls thereof. To reduce pressure pulsations in or after the aftercooler, the length of the conduit 11 is carefully selected. The aftercooler 14 is of conventional construction and comprises vertical tubes externally cooled by water, an oil and water trap 19 and an outlet pipe 17, 18. The compressor shown is doubleacting and has first and second stage cylinders 2, 3 provided with an inter-stage cooler 4.

Abstract: 970,661. Consolidation of plastic clay. BRITISH CERAMIC RESEARCH ASSOCIATION. Dec. 11, 1962 [Dec. 16, 1961], No. 45173/61. Heading B5A. In a method of consolidating plastic clay to produce a homogeneous column of a predetermined cross-sectional shape and size, the clay is passed through two or more pairs, e.g. 11, 12, of power-driven rollers which consolidate the column in all its cross-sectional dimensions. Fig. 1 shows one stage, the lower roller 12 being fixed and the upper roller adjustable on a column 25 by a hand-operated cam device 29. The lower roller may be fitted with vertical flanges 12a between which the upper roller 11 fits, thus closely compressing and confining the clay. Alternatively, endless steel bands may be arranged parallel with the advancing column of clay. The further rollers may be incorporated in the machine or each pair of rollers may be mounted in a separate machine with connecting tables or carriers between adjacent machines. The rollers may be set at any angle, and the clay may be given a final shaping by a pair of finishing rollers to give the required cross-section. The column may be produced having longitudinal or lateral cavities or with internal reinforcement.
