Patent FR-2224589-A1 (FR)
IPC: D21C11/02
Filed: 1974-04-09
Abstract: In the process for the manufacture of bleached sulphite cellulose, using calcium, magnesium or ammonium compounds as white liquor, the washing, sorting (grading) and bleaching of the unbleached cellulose takes place in a closed system, in which the wash liquor runs in counter-current to the cellulose and the effluent from the bleaching is used as wash liquor. To avoid or substantially reduce contamination of waters by effluent from the washing, sorting and bleaching, when the waste liquor is combusted, the chlorine content which leaves as hydrogen chloride is separated out of the off gases before recovery of sulphur dioxide, so that accumulation of chlorine compounds in the circulation (recycling) of the recovered chemicals is prevented. The effluent is neutralised not later than at the concentration/evaporation stage. Further, bases such as ammonium compounds or magnesium compounds, which are harmless with respect to waste liquor combustion, are employed, as is an alkaline oxygen bleach or an alkali extraction following the bleach, the extraction being included in the counter-current arrangement.

Title: Remote temperature measurement system for buildings - performs data recording and restitution using min-computer
Inventor: GERARD HUBERT
IPC: G01K1/02
Filed: 1975-09-04
Abstract: The apparatus described enables the simultaneous remote detection of temperatures in the different parts of the same building or group of buildings. These temperatures are recorded and a determination is made of the mean temperatures of the different rooms or premises. Thermometric sensors are used which are very insensitive to external factors other than temperature. The data are recorded remotely on a mini-computer, this enabling instantaneous data restitution at will. The data are presented in the form of curves. The system may be used to measure also the external temperature and one or more output temperatures on heating systems. This provides the possibility of tracing (or visualising on a screen) the two related curves together with the internal temperature curve for one of the rooms or flats supplied by the corresponding heating system.

Title: Resin impregnated textile preform for lamination to hollow moulding - for mfr. of reproducible radar cones or other shell forms
Inventor: KRAENZLER HERMANN
IPC: B29C70/34
Filed: 1976-09-23
Abstract: Hollow laminated structures involving several layers of resin impregnated fabric, are made by stacking as linings in a mould several independently preshaped uncured preforms which nest ready for mould lamination. The preforms are laid up on suitable complementary plug mandrels. The reinforcement may be based on glass, carbon or boron fibres, impregnated with epoxy, polyimide or polyester resin. Used esp. for making domes or cones for radar communication or other purposes where uniformity and reproducibility of resin density and low void levels are required. The laminates are suitable for mfr. of hollow shapes based on e.g. various solids of revolution requiring smooth faces on the inner and/or outer surfaces, and also suitable in principle for mfr. of storage tanks, boat hulls, etc. Complementary forms are prepd. as sleeves from closed layers of fabrics to avoid the presence of free edges or irregular overlapping of reinforcement, thus reducing radar signal interference. Individual single or double layer fabrics are more readily evenly pre-impregnated than stacked layers treated by coating or laid in a mould to be filled by resin by injection. Use of several independent mandrels avoids viscous drag and fabric derangement typical of preforms laid up on a common former. Avoids use of high energy resin injection equipment.
