Patent FR-2206178-A1 (FR)
Title: Porous plastic material formed from synthetic resin - by evapn. of two solvents only one being capable of dissolving the resin
IPC: C08J9/28
Filed: 1972-11-14
Abstract: A soln. of synthetic resin (e.g. PVC, polystyrene, polyisylidenefluoride, ABS) dissolved in a first solvent (e.g. tetrahydrofurance, chloroform, dimethyl formamide, etc) is mixed with a second solvent (e.g. isopropyl alcohol, ethyl alcohol) which is miscible with the first solvent but incapable of dissolving the resin, and the soln. is pref. impregnated in a pref. synthetic fabric (e.g. woven, nonwoven, knitted). The soln. is then heated to evaporate off the volatile components to produce an extremely thin porous fabric having a uniform distribution of pores which allow passage of ions but prevent passage of particles. The fabric may be used as an air filter or as a separator wall for electrolyte in a battery. The soln. may contain colourants and thickening agents.

Title: Hydraulic distributor for hydraulic presses - has bored housing with spaced circular grooves connected with fluid feed and return channels
IPC: F16K11/07
Filed: 1974-05-30
Abstract: Distributor housing has a bore for a longitudinal slide where there are spaced circular grooves in the bore surface, connected with channels for passing the fluid to and from the slide. Each groove (7-11) is eccentric to the axis of the cylindrical bore while each channel (12, 15, 16, 22) deviates from a section of a groove (7-11) furthest removed from the bore axis (2) to generate a flow resistance in the zone of minimum cross section of each groove. This resistance is more than three times that in the maximum groove cross section and is sufficient for such a deflection of the fluid flow that the flow passes round this zone on the path from the channel (12) to the fluid feed to the channel.

Title: Door for filter which removes odours from a cooking range - having curved guide preventing top edge protruding above upper surface of filter case
IPC: E05D1/04
Filed: 1975-07-16
Abstract: The front opening door of a cabinet for filtering cooking odours has >=1 sliding guide which moves in a groove shaped in a circle arc and supported by the case. The grooves have upper and lower parallel surfaces with a length of 1/4 arc of a circle; the centre of curvature of the arc being in the space bounded by, and including, the planes extending from the upper case surface and the outer surface of the door. One surface of the groove is in contact with the sliding guide when the door is open and the lower surface has a stop at its outer end which contacts the slider edge preventing the door opening further and simultaneously providing a support. The guide attached to the door can be the same circular arc as the groove with the upper surface in contact with the groove and the slide on its lower edge or can have a space between the two surfaces with the slide extending above its upper and lower edges. For the latter the upper groove has a hollow for the slide to fit in when the door is closed. Attached to the guide can be a control flange which makes contact with limit switches as the door is opened to initiate lighting and the intensity of suction. Cupboards, etc. may be mounted immediately above the casing since the door does not project above the upper surface.

Title: Reversing direction of inked teleprinter ribbon - using pinion driven by stepping motor and switched from one ribbon spool to another
IPC: B41J33/518
Filed: 1976-02-24
Abstract: The teleprinter has an inked ribbon printing characters on the paper. This is stored on two spools and is alternately wound on and off each. The paper passes over end rollers and is tensioned by spring loaded shoes pressing it against the rollers. Each end of the ribbon passes through a fork operating a microswitch. To reverse its movement, a metal eyelet in its surface contacts the relevant fork. This actuates the microswitch and reverses a stepping motor driving a pinion. This pinion drives the spools ad switches between them in response to the change in direction of the motor.

The items are removed from the intake surface by a grab (60) with suction heads or other suitable devices, and thruster mechanisms (46, 48) move them horizontally and vertically in order to deliver them into the boxes (C).
Patent FR-2345701-A1 (FR)
Title: Surface displacement or oscillation measurement - uses local interference between two scattered correlated point fields to permit larger stimulated oscillation amplitudes
Inventor: PERRIN JEAN-CLAUDE
IPC: G01B9/02
Filed: 1976-03-23
Abstract: The method measures surface vibrations in the direction normal to the surface using local interference between two correlated point fields produced by scattering light from the surface. It enables unpolished surfaces to be measured and to be stimulated to larger oscillation amplitudes perpendicular to the normal. The average intensity is measured in a region of interference contg. a large number of speckle grains. The two fields are simultaneously produced by two coherent beams incident on the surface at a slightly different angle, and are observed at a slightly different angle dependent on the two angles of incidence.
Patent FR-2345927-A1 (FR)
Title: Vol. proportioning machine for bakeries - with cylinders in turret which can rotate at two speeds
IPC: A21C5/06
Filed: 1976-04-02
Abstract: The machine comprises two vertical cylinders, open at the top, mounted symmetrically on a rotating turret; they are brought successively under a fixed hopper contg. the dough. The turret is driven by the shaft while the pistons are operated by rods linked to a lifting bar which is articulated around the axis. The ends of the rods rest on the cam; this turns around the axis and is driven by a plate and the shaft. The cam on rotating causes the alternating movements of the pistons; these result in dough being sucked into a cylinder when under the hopper and to its ejection in the other position of the cylinder, each cylinder successively occupying these two positions. The turret can turn at low or high speeds; control is by two fixed contacts and levers operated by stops on the piston rods. The low speed of filling the cylinders, by pivoting of the cam alone, with the high ejection speed, by rotating the turret/cam assembly, produces a better prod. and also increases the operating rhythm.

Title: Support for biological purificn. of waste liquids - comprises fibrous siliceous elements with surface of colloidal silica (SW 28.2.75)
Inventor: HELGESSON CLAES IVAR
IPC: C03C25/00
Filed: 1976-08-10
Abstract: A process for the biological purificn. of waste liquids such as water, comprises contacting it with microorganisms on a support to degrade the organic contaminants. The support comprises essentially separate freely suspended fibrous elements comprising >=1 superficial layer of an inert siliceous material the surface of which comprises a layer of colloidal silica. The process is used in a biological purificn. installation which comprises a vessel in which the above support is fixed. A process for conferring bacteriophilic properties to the surface of a siliceous material consists in prepg. a layer of colloidal silica on the surface. The formation of the colloidal silica layer improves the bacteriophilic properties so that a woven structure is unnecessary and the filter is therefore more open.
