Title: Clean release of soap tablet from compression mould surfaces - by interposing sheet material which can form pillow pack sachet
Inventor: DUCROS LUC
IPC: C11D13/28
Filed: 1976-12-03
Abstract: The soap is extruded, cut into tablet lengths and then compressions- moulded into tablets. During the compression-moulding, the tablet is completely enclosed in thin sheet material interposed between mould faces and tablet to prevent all contact between soap and mould faces. The sheet material can be in the form of two superimposed, continuous bands of flexible sheet which sandwich the tablets during moulding and from which moulded tablets ar released ready for packaging. The flexible band material can be PVC., polythene, polypropylene, viscose natural or synthetic fibre etc. Alternatively, the sheet material can be preformed in semi-rigid packaging material, e.g. PVC or card, in order to stay with the moulded tablet as a pillow pack sachet. A similar sachet can otherwise be formed by extruding a plastic tube continuously to sleeve the soap bar leaving its extrusion nozzle. Bar and sleeve are cut to length simultaneously and the sleeve is fin-seamed to a pillow pack during moulding. Clean undamaging release from the mould is obtd. without resorting to demoulding additives in the soap or release lubricants in the mould. The tablet can be sachet packed as moulded.

The water supply pipes may include flow controls (14) and a mixer (13) which are non-accessible to the bather.
Patent FR-2334695-A1 (FR)
IPC: C08F16/34
Filed: 1976-12-13
Abstract: The colour-stable polymers, which contain carboxyl and hydroxyl groups and are obtained by oxidative homopolymerisation of acrolein or by oxidative copolymerisation of acrolein with acrylic acid and subsequent reaction of the polymer with a strong base by the Cannizzaro reaction, do not exhibit the properties ideal, in particular, for cosmetic preparations. This disadvantage is overcome according to the invention by adding alkali metal borohydride in an amount of from 1 to 20 percent by weight, based on the amount of monomers employed, during the preparation of the polymers in aqueous alkaline medium, and treating the mixture at room temperature or above for from 0.25 to 1 hour.

Title: Dry development of exposed diazo copying materials - in contact with a heated developer sheet with a layer of semiconductor oxide
IPC: G03C5/18
Filed: 1977-02-23
Abstract: A process for dry development of diazo copying materials is claimed. After exposing the material, which consists of a layer of a diazo emulsion on a suitable carrier, it is brought into close contact with an oxide semiconductor layer mounted on a suitable carrier. The oxide semiconductor is heated to cause desorption of oxygen, which, in the presence of water, causes the formation of OH- ions. This in turn causes a basic pH which promotes coupling of the diazo cpd. which has not been destroyed by the imagewise exposure, with the coupler. The reproduction element is then sepd. from the developing element. The process allows diazo copying materials to be dry processed without the use of materials evolving noxious alkaline vapours which cause pollution of the atmos.
