Patent FR-2285476-A1 (FR)
Title: Polyprofiled moisture absorbent synthetic fibre - formed of at least two arrow headed portions interconnected by web
IPC: D01D4/02
Filed: 1975-08-14
Abstract: Synthetic fibre having a polyprofiled cross-section is formed of at least two portions each composed of three strips of which the outer strips include an angle of 10-70 degrees and the free ends of the intermediate strips are interconnected by a flexible web. The fibre is used for making clothing articles such as suits, blouses, shirts, headscarves, underwear and socks. Yarns produced from fibres have the properties e.g. feel, of raw silk and are moisture absorbent due to provision of open capillaries by the contiguous strips. Capillary effect can be controlled by yarn twist.

Title: Transient-free stabilised high tension voltage supply - for an electro-magnetic isotope separator
Inventor: ROSENBAUM BENJAMIN
IPC: G05F1/52
Filed: 1975-09-12
Abstract: The circuit supplies >=1 kV typically 70 kV DC. The voltage is controlled at this value, filters protect the control circuits against transients in the mains, and other filters protect the mains against transients from the isotope separator. The rectified voltage from the transformer is applied to the isotope separator circuit through a triode, whose grid potential provides the stabilising control. a fraction of the target voltage is compared with an (adjustable) standard (generated with temp- controlled Zener diodes) and the difference amplified the resulting DC signal is interrupted at 300 Hz transformed rectified and applied to the grid of the control triode. The transformer used has only a single turn primary: this prevents transients being fed back from the separator. The control circuits are protected against transients in the mains by a filter using ferrite blocks through which parallel leads pass in (a) the same and (b) opposite directions, the filter includes also capacitors and varistors. Similar filters protect the mains against transients arising in the isotope separator.

Title: Optical resolution of aryl-pyridyl-alkyl tert. amines - by reaction with optically active maleic acid
Inventor: EPURAN JEAN
IPC: C07D213/38
Filed: 1975-11-06
Abstract: Prepn. of optical isomers of arylpyridyl alkyl-substd. tert. amines of formula (I): (where R is dialkylamino, morpholino, piperidino, pyrrolidino or imidazolino X is H or halogen; n=1-4) comprises reacting racemic (I) with L- or D-malic acid. The resulting L- or D-malate is then purified by repeated recrystn. from various solvents, and the crystallised malate is converted into L- or D- (I) by treating with alkali metal hydroxide in a medium comprising H2O and a water-immiscible organic solvent. The other isomer is recovered from the recrystn. mother liquors. The d isomers of cpds. (I) are antihistamines, and the 1 isomers are local anaesthetics. Optically active malic acid is less expensive than the acids proposed in FR1258226.

Title: Screwed coupling for plastic pipes - has expansion grooves to prevent deterioration if exposed to high temp.
IPC: F16L33/22
Filed: 1976-05-10
Abstract: The plastic pipe (T) fits in the bore of the metal fitting (C) which has a screw thread to suit the nut (E). The nut is provided with a groove to receive the central ridge of the biconic member (B). As the nut (E) is tightened the bi-conic member bites into the wall of the pipe to make leak-tight joint. A sleeve (IF) with two grooves (Cd1, Cd2) is fitted in the bore of the pipe (T). The sleeve prevents the pipe from collapsing under the radial pressure of the bi-conic member. The grooves provide room for expansion of the material of the pipe when it is exposed to high temp. so that the joint is still maintained when the temp. returns to normal.

IPC: A61K47/32
Filed: 1976-05-24
Abstract: Solid water-insoluble, methanol-soluble, hydrophilic polymers are made by polymerising a monomer HO-R-O-CO-C(R')=CH2 (I) (where R is2-3C alkylene group and R' is H or Me), in the presence of water with is not >0.035 wt. % (on wt. of monomers) of a diester of formula: H2C=C(R')-CO-O-R-O-CO-C(R')=CH2 (II). Pref. monomer (I)is 2-hydroxyethylmethacrylate (III) and the diester (II) is ethyleneglycoldimethacrylate (IV). Polymerisation is carried out e.g. using a free radical initiator and with a ratio of (III) to water of 10:90 to 70:30, esp. about 35:65 to give a polymer with a mol. wt. of > about 250,000. The polymers are porous in nature and can easily be washed to a high degree of purity. They are insoluble in water but dissolve in solvents such as (m)ethanol, isopropanol, ethylene glycol, diethylene glycol, etc. The purified polymers are esp. useful for medical applications such as carriers or encapsulating agents for germicides, fungicides, antibiotics, analgesics, etc. In micropulverised form, the polymers are useful in the prepn. of burn dressings.

Title: Cutter for continuous rod cigarette making machine - is block or roller which pulls rod down ahead of cutter blocks
IPC: A24C5/31
Filed: 1976-06-09
Abstract: The continuous rod cigarette making machine has a cutter (7) particularly used on start-up, when the end of the rod (1) is unsatisfactory and must be cut off and diverted into a waste receptacle, and the remainder of the rod allowed to travel onwards. The cutter is forced downwards, bending the cigarette rod downwards towards a receptacle below, and breaking the rod between a pair of blocks (4, 5) preceding it. In this lowered position, the rod then continues over the flat upper surface of the cutter. When the machine is stopped, the cutter lifts, bending the rod upwards against the blocks (4, 5) thus cutting the rod. An alternative design uses a wheel mounted on an arm, which pulls the rod downwards and pushes it upwards similarly for the cutting operation.

The operation of these valves can be automatic, using the temperatures of the liquid. A drainage line (8, 12) into a tank (9) is provided and also an air inlet line (10), both fitted with valves (8a, 10a).

Abstract: La présente invention a pour objet un procédé pour rendre une opération de craquage indépendante d'un dispositif de combustion de CO permettant le traitement des gaz résiduaires de combustion. Elle se caractérise en ce que dans une opération de craquage effectuée dans une unité cyclique avec régénération dans laquelle une masse de catalyseur en circulation entre en contact avec une charge dans un réacteur dans des conditions de craquage et sans hydrogène, puis passe dans un régénérateur dans lequel le coke est évacué par combustion laissant un gaz résiduaire contenant 4 à 9% en volume de monoxyde de carbone et du catalyseur qui retourne vers le réacteur, ce gaz résiduaire étant envoyé dans un dispositif de combustion de CO pour être débarassé de monoxyde de carbone, on introduit dans cette masse jusqu'à 50 % de ppm d'un métal du groupe du platine ou du rhénium. On augmente l'apport en air et on isole le dispositif de combustion de CO de l'unité. Elle se rapporte à un procédé permettant un arrêt du dispositif de combustion de CO et fournissant cependant des gaz de fumée contenant moins de 2 000 ppm de CO.
