Patent FR-2256773-A1 (FR)
Title: Flat semi-permeable membrane with impervious edges - by impregnation of the porous support element in the area of the sealing ring
IPC: B01D53/22
Filed: 1974-01-03
Abstract: A semi-permeable membrane in reverse osmosis applicns. is supported on a porous element and sealed at its edges by a toric joint or other type of gasket. The porous element is prevented from distorting too much when the membrane is clamped in its housing, by impregnation of the pores of the porous element in the area where the membrane is in contact with the element and gasket, to make it more rigid. The impregnation of the element can be over the whole or part of the thickness, or can be by hot pressing of the material onto the surface of the element. The membrane may have a support comprising a central impervious metal on which are porous elements of filter paper treated with formo-phenolic resin, having an area in contact with the membrane impregnated with polystyrene 5-75% of their thickness. Used for semi-permeable membranes for treatment of solns. by reverse osmosis or ultrafiltration, e.g. de-salting of sea water or for the treatment of gas mixts. by gaseous permeation. The added rigidity to the support element enables the joint to form a better seal reducing losses between untreated and treated fluids, so that the appts. can work at higher pressure. Wear of membrane is reduced since lack of deformation of support element prevents stretching and tendency to tear.

Title: Automatic pressure valve for compressor - has inner surface of closure member below piston top dead centre when closed
IPC: F04B39/10
Filed: 1974-01-08
Abstract: The valve has a valve housing, closure member, valve housing, closure member, valve stop and spring. The closure member is so dimensioned that, when closed, its surface facing the top of the piston lies below the plane of the pistons top when in top dead centre. The arrangement is preferably such that, when the piston is in the region of top dead centre, the closure member comes to rest on the piston top until it re-seats when the piston moves down. The closure member may consist of two or more concentric elements whose inner surfaces when closed, lie below the top dead centre plane of the piston top.

Title: Machine for mixing and applying plaster - uses feed screw with variable pitch and radial or axial mixing bars
IPC: B28C5/12
Filed: 1974-03-19
Abstract: The machine for the mixing and application of plaster obviates use of discharge pumps with attendant wastage etc. by using screw conveyors to mix and discharge the plaster.

Title: Extra-slow-speed ram - has piston thrusting fluid out through adjustable orifice under air pressure
IPC: F15B11/076
Filed: 1974-06-05
Abstract: An apparatus for dipping spectacle frames in a colouring bath employes a very slow moving ram which raises and lowers the carrying frame.

Title: Silage batch removal mechanism - has horizontal slide carrying cutter moved by rope running over rollers
IPC: A01F25/20
Filed: 1974-11-20
Abstract: The batches of silage are removed by means of a frame mounted on a tractor with a fork at the base, with a cutting mechanism, on a slide travelling horizontally, and also moving up and down independently in the form of a ram-operated knife. The slide (13) carrying the mechanism travels along its track under the action of a rope (22) running over rollers. The ends of the rope furthest from the slide can be wound in opposite directions onto separate sections of a common drum, mounted near the rearmost portion of the frame. Alternatively it can form a closed loop driven by a double-acting ram, whose piston rod carries a mechanism alternately gripping and releasing the rope depending on the direction of rod movement, so as to move the cutting mechanism by stages from one end position to the other.
