Patent FR-2043564-A1 (FR)
Title: Plastic foam core for vehicle body mould- - ing
IPC: B29C44/58
Filed: 1970-04-24
Abstract: Production of a hollow plastic body by the use of a disposable plastic core. The core of the vehicle body mould is made of expanded polystyrene. After filling the mould with a chemically blown plastic foam which totally encloses the polystyrene, the latter disintegrates under the heat and pressure generated by the chemical reaction of the outer foam, thus leaving a cavity in the mould.

Title: Cyclisation of polydienes at high tempera- - ture
IPC: H01B3/44
Filed: 1970-05-06
Abstract: The polymers are formed by heating of homo- or co-polymers (I) having residual unsaturation, at more than 200 degrees C (pref. 250 - 300 degrees C) for at least 60 min. in absence of oxygen. I may be polybutadiene or polychloroprene. The polymers I cyclise with disappearance of unsaturation giving hard and sometimes clear thermoplastics having high tensile strength, heat and oxygen resistance. The method can be used for cyclisation during moulding which alleviates handling difficulties with precyclised polymers. It is suitable for injection or extrusion moulding processes for production of films, fibres, tubes etc., and can be used in impact resistant wind shields for aeroplanes.

Title: Coating process with gastric juice-resistant soln - - for gelatine capsules
IPC: A61J3/00
Filed: 1971-05-14
Abstract: In prior art, the solubility of the gelatine envelope has been reduced by treatment with formaldehyde in a dry atmos. or by coating them with a thin film of resistant varnish. The results obtd. have not been reproducible and have not proved stable with time. In the new process, the hard gelatine capsules are coated with a film by spraying and simultaneous drying of a soln., which is resistant to gastric juices, while the capsules are in movement in a coating turbine, under reduced press. The coated capsules have a good appearance because of the uniformity and transparency of the film; good reproducibility is obtd. The spherical coating drum rotates around an oblique axis, and is charged with about 100,000 capsules and the lid is placed in position and partially sealed. With the drum in rotation the resistant soln. is introduced through a spray nozzle at the rate of 500 ml/min. Simultaneously a current of air at 60-80 degrees C is admitted; this dries the soln. in proportion as the latter coats the capsules.
