Patent FR-2288235-A1 (FR)
Title: Air generator with turbine in horiz. passage - has chimney and outlet with discharge fans connected to passage
IPC: F03D9/00
Filed: 1974-10-14
Abstract: The equipment consists of a vertical chimney (1) opening into a smaller diameter horizontal section. This section houses an air turbine, which is connected to an electrical generator or other mechanical drive (6). The discharge duct (4) opens onto a discharge section (7) of increased diameter which contains a number of extraction fans (5). The fans are electrically driven from the generator (6). The entire system is insulated against radiation losses. The kinetic energy of the mass of air in motion is greater than the power required to drive the fans, resulting in an excess of generated power.

Title: Multiple point electrode prevents electrostatic charge accumulation - and has two twisted wires trapping bundles of pointed conductors
IPC: H05F3/02
Filed: 1974-12-24
Abstract: The multiple-point electrode, for preventing the build-up of electrostatic charge, consists of two or more strands of bared conducting wire twisted together and holding bundles of pointed conductors between pairs of twists or crossovers. The wires may each be composed of several strands. The bundles of pointed conductors may be tinned or silvered wires soldered together at their middles and with their pointed ends projecting outwards at right angles to the axis of the stranded wire that is holding them. The advantage of this 'antistatic' electrode structure lies in its simplicity and cheapness.

Title: Panels for aircraft compartments - have skin which peels for rapid pressure release without detriment to structural strength
IPC: B64C1/18
Filed: 1976-02-19
Abstract: The explosion-proof aircraft compartment panel consists of a grid (1) made up of metal strips, with filling material (2) around the edges to constitute a load-bearing frame. The grid has a skin (3) soldered or glued to one side, but over part of the panel (e.g. one corner) the adhesive is omitted. In service, panels are fitted in such a way that a sudden reversal of the normal pressure balance across them will progressively peel off the skin, starting at the loose corner, allowing a rapid escape of gas. Suitably shaped filler blocks can be glued to the skin in the grid spaces, to provide a more level surface.

Patent FR-2351040-A1 (FR)
Title: Straight lengths of hollow fibres for dialysers, etc. - from windings lowered successively along guides into vibrated containers
Inventor: AMICEL CHARLES
IPC: B65H81/00
Filed: 1976-05-10
Abstract: Devices incorporating bundles of hollow fibres laid in a straight length or in hairpin fashion, parallel to each other are produced by winding at least one hollow fibre around and in contact with two guides spaced some distance apart so that flat hollow coils of fibres are obtained. Each coil forms a loop around each guide and runs between the guides in two near enough straight lengths. The movement of the guides advances the hollow coils, as they are wound on towards the ends of the guides, and when they have left the guides, the hollow fibres are practically in straight lengths. The profile of the guides is such that as the hollow windings advance along them, the yarn can relax into an untensioned condition. This elimination of tension may also be effected by guides which change their relative position, or by means of a guide formed from a rod on which external windings are provided. A mechanism may also be fitted on the guides which has a motion identical with that of a sewing machine feeder, or one of the guides may be vibrated. Arrangement produces straight lengths of hollow fibres which do not shrink after being cut at their ends, since they are wound near enough without any tension and when they leave the guides they are practically already in straight lengths.

Title: Guide for wire coils on spool - has pair of spaced guide rolls forming loop in two segments
IPC: B65H54/28
Filed: 1976-11-10
Abstract: A wire coiler comprises a spool on which adjacent turns of the wire are coiled, the spool being located in a housing supporting a movable wire guide. The guide is disposed upstream from the winding head in which the spool, rotated by a motor, is located. The winding head comprises two plates turning on a common axis to rotate the spool and two guide rolls which are parallel and are equally distanced from and on opposite sides of the axis of rotation of the spool. The rolls help to form a loop after the wire guide and before the wire is coiled on the spool. The loop comprises two segments which peripherally contact the spool hub on two diametrically opposed points to ensure that the part of the wire which is being coiled on the hub forms in successive adjacent turns with superposed layers forming successively in opposite senses.
