Title: Pneumatically operated reciprocating piston concrete pump - pistons force charge past central distributor to discharge pipe
IPC: F16K11/08
Filed: 1974-06-19
Abstract: A concrete pump has a sloping hopper which delivers material into a reciprocating distributor (4) with an open mouth which discharges the material horizontally into one of a pair of tubes (1, 1a) each containing a piston (2, 2a) so that as the piston (2) in that tube moves outward, it sucks the material inwards into the mouth of the pipe (1). This distributor is supported on a rotating base which is oscillated by a pair of pneumatic pistons underneath the casing, the upper part of the distributor, and the base forming its lower part, being supported by sealing rings to exclude harmful grit and water. As the distributor pivots about a vertical axis, the pistons are reversed, the charge is forced past the distributor and out through the discharge nozzle (8) while the other piston (2a) draws in a fresh charge ready for the next cycle. Clamping rods (29) form a quick release system for separating portions of the casing for cleaning.

Patent FR-2258451-A1 (FR)
Title: Automatic red wine fermentation tank - with sprinkling arrangement for the must
IPC: C12G1/032
Filed: 1975-01-22
Abstract: Automatic fermentation tank, for use in making red wine comprises a fermentation compartment sepd. from a sprinkling compartment by an inter. base. The compartments communicate through an elevator tube along which the must is forced into the upper chamber by the press. of the fermentation gases disengaged in the fermentation chamber. The must is periodically returned to the latter through the mass left when the hollow, inverted cone is lowered by the press. of the must exerted in the small end of the c ne against the action of a spring and a cable. The returning must, in free and direct fall, floods the layer of marc; this enables the desired yield of pigment from the marc to be attained in the shortest possible time. When the upper compartment contains no more must, the press. exerted by the liq. on the cone is reduced to zero and it is brought back to the closed posn. by the spring. The level of the liq. rises and the gases can no longer escape. The press. builds up and the must is again forced into the upper compartment and the cycle is repeated periodically. The pigment extn. is improved by the rapid and intense sprinkling of the layer of marc by the must through the inverted cone.
