Patent FR-2237974-A1 (FR)
Title: Electrolytic cell - for aluminium and magnesium recovery from chloride solns
IPC: C25C7/00
Filed: 1973-07-19
Abstract: The cell has a wedge-shaped anode, taper about 10 degrees, and correspondingly shaped cathodes on either side. The distance between the two electrodes is pref. 3.5-4.4 cm for a current density of 1.5 A/cm2. In operation, the gas liberated collects in a space between the top of the cathodes and the soln, and can be drawn off from there. This gas removal chamber is pref. at least twice as high and wide as the distance between the electrodes. Gas is thus prevented from collecting round the cathode and reacting with this. Investment costs are three quarters, and operation costs one quarter, compared with conventional equipment.

Title: Flexible floor covering tile with interlocking edges - has grooves crossing at corner on each two adjoining edges
IPC: E04F15/02
Filed: 1973-10-09
Abstract: A floor covering method using tiles which may be of rubber or plastics material, uses superimposed integral tiles with the upper tile offset diagonally on the lower tile, the contact faces of the tiles being designed to give an accurate location without sliding. The contact faces are grooved along two adjacent sides, inset from the edge so as to leave a hooked edge, giving an interlocking effect, the grooves being bridges at two points forming a stop for the other tile edge. This overlapping arrangement enables the surface to be covered in an even, smooth manner.

Title: Fibrous sheet, e.g. paper, prodn appts. - having mechanism for varying space between mould periphery and feed plate
IPC: D21F1/04
Filed: 1974-08-06
Abstract: A fibrous web (e.g. paper) is formed by feeding pulp through an inlet into a pulp dispersion chamber and feeding the pulp from the dispersion chamber through a vent onto the surface of a rotating perforated drum to form a layer of the pulp on the perforated drum. Downstream of the vent a curved plate forms with the surface of the drum a forming zone in which the layer of pulp is pressed against the surface of the drum to form a fibrous web on the surface of the drum. The dispersion chamber includes formations to produce a 90 degrees change in the direction of flow of the pulp through the dispersion chamber and so creates turbulence in the pulp and the curved plate is so positioned as to maintain the turbulence in the pulp in the forming zone. A preliminary mixing chamber for the pulp is dispensed with. The formations in the dispersion chamber to produce the turbulence may comprise a baffle plate or an inverted U-shaped formulation around which the pulp flow has to deviate.

Title: Single to double glazing conversion - using split frames hinged with rods and eye-bolt to original frame
IPC: E05D3/02
Filed: 1974-10-18
Abstract: The unit allows single-glazed windows to be converted to double-glazed windows, the unit being simple and cheap and does not require the use of any special tools for installation. It is especially useful for hinged windows although it could be adapted to suit sliding windows. It also allows easy access to the space between the two window-panes for cleaning purposes. The wooden frame contains a groove into which the panel of glass is fitted. To enable the glass to be fitted quickly, the frame is made in two halves which are assembled round the glass. To attach the frame to the original window, small grooves are made along one edge of the frame, in which are placed flat-headed eye bolts protruding from the original window frame. Hinge-pins are then placed in the ends passing through the frame and the eye-bolts.
Patent FR-2296820-A1 (FR)
Title: Boiler for domestic central heating - has heating coil within combustion chamber for rapid heating of part flow
IPC: F24D3/02
Filed: 1974-12-31
Abstract: The boiler has a conventional flow (D) and return (R). A branch connection (4) from the flow is taken to a small accelerator pump (3) which draws off part of the flow and forces it through a coiled heat exchanger (1) from which it returns through a branch connection (5) in the return. The heat exchanger (1) is placed within the combustion chamber (2) of the boiler and is protected by suitable refractory material. The circuit contains isolating valves (6) and a regulating valve (8). The accelerator (3) is controlled with the burner so that it is on only when the burner is on. Heating a small portion of the total liquid flow with the very high temperature in the combustion chamber gives more efficient heat transfer and raises the overall efficiency.

Title: Ergosterol and ubiquinone 9 prodn - by hydrolysing a biolipid fraction from the biomass of yeast strains
Inventor: TARASOVA NINA VASILIEVNA
IPC: C12P7/66
Filed: 1975-01-14
Abstract: Simultaneous prodn. of ergosterol (E) and ubiquinone 9 (U9) comprises hydrolysis of the biolipid fraction separated from the biomass of E- and U9-producing yeast strains with alcoholic alkali (pref. methanolic KOH) in the presence of an antioxidant which inhibits the oxidation of E and U9 (pref. pyrogallol); extraction of unsaponifiable components of the hydrolysed mixture (pref. with Et2O); evaporation of the extract until crystals of E are formed; separation of the crystals from the mother liquor; adsorption chromatography of the oil prod. remaining after the removal of the extraction solvent; and pptn. of U9. Ergosterol is used as a starting material in the prodn. of vitamins of the D group (including their metabolites) and of steroid hormones. Ubiquinones (including U9) are active in cardiovascular insufficiency and have a heating effect in alimentary and genetic dystrophy in animals; they also have an effect in human anaemias involving protein metabolism disorders. Simultaneous production of high-purity E (yield 10-15 g/kg biolipid fraction) and U9 (yield 1.2-1.7 g/kg biolipid fraction) may be obtd. from industrial yeasts used in the production of fodder or food protein. Removal of the E- and U9- contg. biolipid fraction from the yeast biomass improves the quality and stability of the protein fraction.

Title: Clean air working enclosure - has cooler at inlet of fan delivering air to passage at back of hood
IPC: B25H1/20
Filed: 1975-08-07
Abstract: A worktable is surrounded by a three sided rectangular hood. A fan (6) delivers air into a passage at the back of the hood from which it flows along the side and through openings in the side across the hood. The main flow (4) is horizontally through the hood itself. Vertical plates (8, 9) delimit a narrow opening in the side at the front of the hood through which a smaller part (3) of the air flows to form a laminar air curtain between the operator and the working area. There is a chiller (7) on the other side of the hood on the fan inlet. Cooling the air prevents natural convection from pulling the air curtain away from the front of the hood.
