Patent FR-2138968-A1 (FR)
Title: Continuous sepn device - for removal of fine solids from a suspension
IPC: C02F11/125
Filed: 1972-05-24
Abstract: Device is partic. intended for the removal of finely-divided solid matter from the liquid portion of sewage and chemical sludges. The suspension is first flocculated. Sepn. is effected in a multistage screw press with a permeable cylindrical jacket surrounding the screw. In the process the sludge is subjected both to press. and to a vigorous agitation. The suspension is first fed, together with the flocculating agents, into a cascade mixer; it falls, by gravity, through a hopper into the endless screw press which is divided into a number of stages and is surrounded by a permeable envelope. The dia. of the latter is adapted to the different stages of the screw. A number of retaining rings project into the screw channel and cause the solid matter to be compacted with an increased sepn. of the liquid. A press. cone is provided at the discharge outlet which can be closed on starting unitl an initial press. is built-up in the channel. Once the machine is working continuously the cone is not longer required.

Title: Practice torpedo ballast release system - has ring of segments around casing ejected by springs after securing strap is broken
Inventor: DELUCHE CHRISTIAN
IPC: F42B19/42
Filed: 1976-04-09
Abstract: A method of removing the ballast from a practice torpedo enables it to be lightened so that it will float after completion of firing practice. The casing (9) of the torpedo carries a set of weights in the form of segments (5) integral with the casing. All the segments have pockets through their abutting edges and an abutting pair of pockets (8) forms a chamber for a spring (10).

Title: Union for non-coaxial conduits - has compensating eccentric socket pairs or barrel shaped angle pieces
IPC: F16L27/073
Filed: 1976-04-09
Abstract: The compensating union connects together sections of conduit which are of different cross-section, out of alignment or at an angle to each other. The union is particularly suitable for gas and central heating appliances. Lack of alignment is compensated by connecting to the threaded ends of each conduit one of a pair of interlocked internally-threaded sockets (1, 2). Each of these sockets widens out into a flange, which the socket enters offset from the centre. By rotating the sockets relative to each other, a range of eccentricities can be accommodated, up to the sum of the two socket eccentricities. The sockets are locked together by a rectangular groove and rim arrangement, and sealing is achieved using a ring (6) between abutting shoulders (4, 5).
