Patent FR-2009055-A1 (FR)
Title: Measurement of gas adsorption by solids
IPC: G01N27/12
Filed: 1969-04-03
Abstract: Simultaneous measurements are taken of the electrical resistance of the solid and the quantity of gas adsorbed as gas passes over the solid. Since the electrical conductivity of the solid varies proportionally with the degree to which chemical adsorption has taken place, it follows that by measuring the total adsorption & simultaneous electrical resistance of the solid, it is possible to determine the degree of physical adsorption. The apparatus comprises electro-chromatographic equipment to deal with a powered sample, preferably of grain size about 0.3mm.

Title: Appts for permeation through hollow fibres - allows simple construction and efficient separation and mixing processes
IPC: B01D63/04
Filed: 1973-03-19
Abstract: Appts. for sepn. or mixing of fluids consists of a stack of discs in a shell. The discs are made of hollow fibres, woven into a fabric, mounted in a frame so that the ends of the fibres emerge at its outer circumference. The discs are stacked and the stack is enclosed between perforated end plates and surrounded by a porous casing. The whole is fitted into the shell so that there is a space between the porous casing and the wall of the shell. The end plates of the shell have feed and discharge nozzles respectively and the bear on to the perforated end plates of thestack and are held tight by bolts drawing them together. There is a permeate nozzle in the shell wall. In separation processes, feed fluid flows perpendicularly across the discs and permeate flows through the walls of the hollow fibres and out across the porous casing and through the permeate nozzle. In mixing processes one fluid enters through the permeate nozzle, flows across the walls of the hollow fibres and mixes with the other fluid outside them. Separation processes envisaged are ultra-filtration, reverse osmosis gaseous permeation. Mixing operations are solution of gas in liq. vaporisation into gas. The appts. is simple to make and ensures good contact between circulating fluid and hollow fibres.

Patent FR-2237350-A1 (FR)
Title: Power generation from hydrogen and oxygen - combustion products are fed to turbines and water vapour condenser
IPC: F01K25/00
Filed: 1973-07-13
Abstract: Power generation is based particularly on the hydrogen produced by atomic reactors. It is more efficient to carry hydrogen to local generating stations than to transmit electrical power over a grid system. Power storage can be facilitated by the storage of hydrogen. Hydrogen, oxygen and water vapour are introduced into a combustion chamber in stoiometric proportions and the resulting energy transmitted via a heat exchanger to a series of turbines driving dynamos or alternators. A sensor measuring oxygen/hydrogen content of the low pressure output vapour controls the input of these gases to the combustion chamber. Water vapour from this source is also fed back to the chamber.

A mixt. is formed contg. tetralone-1 and tetralol-1, non-reacted tetralin is distd. off in vacuo at ca. 125 degrees C, and the tetralol-1 is then dehydrated by heating at 130-160 degrees C using anhydrous alum catalyst, in the liq. phase to form 1,2-dihydro-naphthalene, followed by distn. at a max. press. of 30 Torr and then distn. of the remaining tetralone-1 at a max-press. of 10 Torr. The tetralone-1, is a useful organic inter. esp. in the prepn. of naphthol-1. The chemical conversion of the tetralol-1 into another prod. with different physical chem. properties facilitates the sepn. of tetralone-1 which is obtd in high yield.

Title: Film resistors coated with glaze by flame-spraying - suitable for use in high vacuum and for heavy thermal loads
IPC: H01C1/034
Filed: 1974-04-03
Abstract: Electric film-resistors consist of a ceramic substrate, the resistor layer and a glazed coating, where the resistor is pre-heated and the glaze applied by flame-spraying using a glaze which, in the molten state, does not react with the resistor layer. The resistance film may consist of carbon, metal, metal-oxide, or a conductive glaze, on a ceramic substrate with end-caps and connecting wires which can be used to hold the resistors during the flame-spraying process. After the initial pre-heating, the finely-powdered glaze is pref. applied in stages, the glaze being melted by the flame after each stage. In this way, a coating free of gas bubbles is obtained. A separate flame can be used for pre-heating and the process is suitable for mass-prodn. The glaze confers excellent resistance to moisture and gases, with high dielectric strength, and is far superior to synthetic resin coatings.
