Patent FR-2129904-A1 (FR)
Title: Artificial leathers - mfd in a single pass process free from wash treatments or solvent recovery
IPC: D06N3/14
Filed: 1971-03-19
Abstract: Leathers are made by impregnating a fibrous substrate with a fixing agent, then coating one face of the substrate with a soln. of emulsion of a resin followed by pressure to impregnate and coagulate the resin in or near the substrate surface. The excess solns./emulsions are then stripped/evaporated off. A further resin coating may be applied to the initial coating to obtain special effects on the 'flower' face of the leather-cloth. Used for impregnating mats of natural or synthetic fibres with e.g. polyurethane, PVC, cellulose triacetate, nitro-cellulose, styrene-butadiene or butadiene-acrylonitrile resins, without the fixing agent having to diffuse from the coated surface of the substrate.

Patent FR-2146944-A1 (FR)
Title: Freezing conveyor band - cooled by direct sliding contact with refrigerating evaporator
IPC: F25D13/06
Filed: 1971-07-27
Abstract: A refrigerant evaporator is placed in direct contact with the underside of a metal conveyor band to freeze products, particularly foodstuffs, carried on top of the band; a thin film or liquid may be employed as lubricant between evaporator and band, provided the liquid will not freeze and has a high coefft. of heat transfer. The principal disadvantages of air-blast freezing are thus eliminated, e.g. dehydration and loss of weight and flavour of food products, as well as discolouration; the efficiency of heat transfer is low. The proposed system is also cheaper to install and maintain than those employing conveyor bands cooled by contact with secondary refrigerant liquids.

Title: Ultrafiltration and ultracentrifugation of liquid protein materials - pref. milk to obtain natural calcium phosphocaseinate
IPC: A23J1/20
Filed: 1974-11-29
Abstract: Protein contg. materials are enriched in protein by first subjecting the liquid to an ultrafiltration through a semi-permeable membrane to form an ultrafiltrate and a retained liquid which has a higher N content than the starting material; the retained liquid is then ultracentrifuged at 20,000-200,000 x g to give a supernatant liquid and a precipitated protein product. Also skimmed milk is treated as above by ultrafiltration through membrane of pore diameter is no >30 m mu at 1-20 kg/cm2 and 4-60 degrees C, followed by ultracentrifuging to give a product which is substantially natural calcium phosphocaseinate. Also food products for humans and animals, particularly cheese, are made from the above products. The products are used in human and animal feeds, especially in cheese. Previously processes for caseinates have given products inferior to natural Ca phosphocaseinal both in P content and in emulsifying and thickening power; also the by-products from these processes are difficult to use. The above gives natural Ca phosphocaseinate and by-products which are easily used.

Title: Automatic continuous filtration of molten plastics - with intermittently displaced band filter
IPC: B29C48/692
Filed: 1975-11-24
Abstract: Process for filtering molten plastic material through a band filter moved intermittently by external traction through a filtering chamber sealed by plugs of plastic material formed at the entry and exit points of the band. While the band is stationary the temp. at the entry and exit points is kept low enough to maintain the seal, but when the band is to be displaced the temp. is raised so that the plugs are softened sufficiently at the edges to allow the band to move. The band may be moved automatically and its displacement predetermined. The temp. is pref. raised just to release the band and immediately reduced again after the required displacement. The filter is more effective than previous similar devices. It avoids loss of material from the plugs and the necessity of braking the band motion.
