Patent FR-2234113-A1 (FR)
Title: Explosive cartridge casing has cellulose and nitrocellulose fibres - and is formed by pressing against former using elastic membrane
IPC: C08L1/18
Filed: 1973-06-21
Abstract: An explosive cartridge casing is formed by introducing a paste of adhesive and cellulose and intro-cellulose fibres around a perforated former arranged within a housing lined with a cylindrical flexible membrane(s) and introducing a pressure fluid between the housing wall and the membrane so that the membrane presses the paste against the former and slopes it into a sleeve. The interior, of the former is simultaneously maintained at a reduced pressure to remove volatile components from the paste. The method is used for forming the casings of gun cartridges. The casing burns completely and doesn't heave to be ejected.

Title: Purifying and upgrading milk by-prods - using sterilising ultrafilters followed by fermentation
Inventor: DARDENNE JACQUES
IPC: A23C21/02
Filed: 1974-06-13
Abstract: Milk (by-)prods. from e.g. cows or sheep, or cheese and butter factories, are purified and up-graded to avoid the pollution of waters into which they might be discharged, and to obt. commercial prods. such as proteins, metabolites, etc. The milk prod., such as milk serum, from the storage tank is fed, opt. with pretreatment, into a membrane ultra-filter unit under pressure and in a state of high turbulence. The concentrate, contg. proteins and fatty matter which do not pass through the filter, passes to a tank. It can be stored as it is or treated by electrodialysis to separate different protein fractions such as lactalbumins, lactoglobulins and immunoglobulins etc. A simpler method is by spraying or freezedrying. The filtrate which permeates through the membrane is treated by a fermentation process. If filamentary moulds are used the prod. is a biomass which is rich in proteins. The withdrawn filtrate can be rejected in water or still may be further treated by reverse osmosis. The water finally sepd. is largely stripped of polluting materials and can be discharged into a stream without damage. It can however be further treated to render it chemically pure.
Patent FR-2274865-A1 (FR)
Title: Liquefied gas tank filling process - detects pressure rise on immersion of sprinkler at max. filling level
Inventor: GIRARD JEAN JOSEPH MARCEL
IPC: F17C6/00
Filed: 1974-06-14
Abstract: The process is for use with a low temperature tank thermally insulated from its surroundings, and involves using a sprinkler pipe discharging into the tank at the maximum level of liquid (H). The steady fall in pressure during the major part of the filling operation is monitored, and the pressure rise is detected at the moment of immersion. The filling operation is then halted. Injectors can be used, discharging the liquified gas in droplet form in the gas-filled portion of the tank. The pressure detectors can be mounted on the flexible filling connection, e.g. on the control handle, and can be arranged to stop filling automatically on detection of pressure rise.
