Patent FR-2290246-A1 (FR)
Title: Transformation of liquid products into small granules - by press injection into a bath of refrigerant
IPC: A23L3/375
Filed: 1974-11-07
Abstract: Small deep-frozen balls or granules are produced by injecting a non-gaseous fluid into a refrigerant which is at vaporisation point, the size of the granules obtained being a function of the temp. difference between injected liq. and refrigerant and also of the injection press. The deep-frozen granules are removed directly from the bath to a vacuum chamber where almost all the refrigerant is evaporated from them and is returned to the freezing bath. An alternative system is to have a refrigerant bath that is airtight and operates under press. increasing the boiling temp. of the refrigerant. Excess refrigerant on the frozen balls is still removed in a vacuum chamber and re-injected into the pressurised bath. Liquids are injected into the refrigerant bath through sprays in the refrigerant, which is usually at atmos. press. and are removed from the refrigerating liq. by a conveyor which tips the frozen balls into a hopper connected by means of a rotating sealing valve to one or more vacuum chambers in parallel. The vacuum chambers are linked to a single vacuum pump, which evacuates the refrigerant vapours and returns them to the refrigerant bath. The chambers have at their outlets similar valves to the inlet so that a vacuum is maintained even during the emptying of the frozen granules. For refrigerant baths that operate under press. the vaporised refrigerant can be returned directly from the vacuum pump or can be re-liquified then injected into the bath. Process is used for deep freezing granules of liqs. in the food industry, e.g. coffee, crushed fruit juices, etc.

Title: Tablet comprising enzyme and polyethylene glycol - to reduce enzyme deactivation during tabletting
IPC: A61K9/20
Filed: 1974-12-03
Abstract: A tablet contains >=1 enzyme and polyethyleneglycol. The tablets are made by mixing the enzyme with polyethyleneglycol and pressing the mixture into tablets. Also tablets are made by adding >=1 enzyme to a solution contg. polyethylene glycol, screening the mixture, incorporating an excipient and a binder, kneading the mixture, transforming the dried product into granules, mixing the granules with a lubricant, tabletting the mixture and if desired coating the tablets with a film. Previous attempts to incorporate enzymes into tablets have resulted in loss of activity or decomposition apparently due to the compression, heating, friction etc. during tabletting. By incorporating polyethyleneglycol this deactivation is largely avoided and the tablets obtained are stable to storage.

Title: Open end spinning device fed with fibres from opening roll - has deflector surface against which waste is flung from opening roll
IPC: D01H4/36
Filed: 1975-01-17
Abstract: A spinning rotor of an open end spinning device is fed with discrete fibres passing through a feed duct connecting with a cavity of a housing in which an opening roller is mounted, the discrete fibres being produced on the periphery of the opening roll by opening a sliver fed to the opening roll. Heavier waste in the sliver is flung from the opening roll against the cavity wall and passes across the mouth of the feed duct and strikes a deflector surface downstream of the feed duct. The deflector surface directs the waste into a waste removal duct through which it is exhausted. Arranging the waste removal duct downstream of the feed duct provides a more compact arrangement. The deflector surface ensures that the waste passes into the waste removal duct and doesn't stay in the cavity in which the opening roller is mounted.
