Patent FR-2263567-A1 (FR)
Title: Method of multiplexing complex command signals - uses integration of signals formed from pairs of rectangular waves
IPC: G08C19/22
Filed: 1974-03-04
Abstract: A signal formed from successive pairs of rectangular waves is modulated in response to the command by modification to the cyclic relation of the first and second peaks of each pair. The respective duration of which can be independently and selectively accrued by an adjustable value lower than a step value or by a fixed value greater than the step value. The signal is integrated to produce a zero value continuous voltage which has a variable value lower than a step value or a fixed value greater than the step value. The voltage ensures execution of the complex command, whilst discriminating the orders of which it is compared as a function of the polarity and the value of the voltage.

Title: Electrostatic filter to remove dust from air or exhaust fumes - employs cheap electrically non-conductive fibrous dust-collecting mesh
IPC: B03C3/155
Filed: 1974-03-04
Abstract: Particles of dust suspended in an air or gas stream become ionised by an electrode, usually a charged wire, upstream of a dust collector which comprises a pair of perforated, collector plate electrodes which are spaced apart to sandwich a fibrous, filter mesh made of electrically insulating material. The filter mesh may take the form of band which can be moved on fro a supply roll to a take-up roll. It is much cheaper to renew this type of collector mesh than the electrically-conductive mesh sheets which were previously necessary.

Title: Leather resistant to calcium chloride - obtd. by double retanning, nourishing, waterproofing and treating with poly:ol
IPC: C14C9/00
Filed: 1976-04-23
Abstract: A process for making a leather resistant to prolonged contact with calcium chloride is described. After normal chrome tanning, the leather is re-tanned first with glutaraldehyde and then after neutralising in another bath with synthetic or plant tannins. In the course of the retanning the leather is nourished using a sulphited animal oil. The re-tanned leather is then impregnated using chromium stearatochloride, polyfluorane or aliminium stearate. A polyalcohol is then added followed by stirring after which the leather is curried, dried and finished in the usual manner. The leather obtained retanned with 5% glutaraldehyde and 12-16% tannins and treated as abovefinally using 1% polyalcohol has a resistance falling by 8%, compared with 40% for untreated leather, in a Bally penetrometer test using a specific CaCl2 soln. The leather is particularly used for making safety shoes e.g. for workers in mines.

Title: Dangerous waste disposal system in ground - uses sealed and covered trench compressed before covering with arable land
IPC: B09B1/00
Filed: 1976-06-10
Abstract: The system allows safe disposal of dangerous material such as asbestos waste without risk of pollution. A fully sealed trench is formed to take the material, which is then covered with a hermetic sealing layer, after which the whole is compressed to a minimum pressure of 4000 kg per sq. metre, and then covered with a layer of arable land. The excavation is made in clay, which is used for the covering layer. The basic hydrated alumina silicate of the clay causes natural bio-degradation of any toxic material, while the natural stratification and compression produces a long-life shist which will retain the asbestos in the mineral state.

Patent FR-2320143-A1 (FR)
Title: Centrifuge for impregnating or resin-embedding small components - has tilting moulds in communication with feed chamber(NL080277)
IPC: B29C39/08
Filed: 1976-08-04
Abstract: A rotary impregnating or casting device comprises one or more moulds, each intended for housing an article to be impregnated or embedded in resin. These moulds can be rotated (centrifuged) about a central axis and supplied from a synchronously revolving central chamber with the casting resin. The moulds are all heated. Each mould is pivotally mounted upon an axis which is transverse to the rotational axis of the system. The moulds can thus swing between an at-rest position, in which their centre of gravity is immediately below their axis of rotation and an operating position in which they swing outwards under centrifugal force. This brings each mould inlet duct into pressurised contact with the outlet from the synchronously revolving central chamber, and enables the resin to flow outwards from the chamber into the mould. The outward centrifugal swing of each mould as the entire system revolves forcibly applied its inlet to the outlet from the chamber and forms a sealed contact between them. Used e.g. for embedding in resin small electrical components such as rotors, windings and the like. The moulds are easily accessible and easy to open. The articles to be impregnated can be simply placed in each mould and do not need to be specially supported in position. Since the only physical contact between each mould and the central chamber is a sealing ring of thermally insulating material, the transmission of heat from the mould into the synchronously revolving distribution chamber is minimised, thus preventing premature hardening of the resin in the distribution chamber. No heating flame or bell for moulds is necessary.
