Patent FR-2501714-A1 (FR)
Inventor: GEOLIER CHRISTIANE SIMONE EMIL
IPC: C12H1/10
Filed: 1981-03-11
Abstract: Food liquids such as wines are deacidified by removing malic acid without substantially affecting the tartaric acid content of the liquids. Deacidification is carried out by adding to the liquid calcium carbonate, potassium bicarbonate, calcium tartrate and a calcium double salt of tartaric and malic acids to cause precipitation of crystals of tartromalate from the liquid. The amount of calcium carbonate is sufficient to increase the pH of the food liquid to 4.5. The amount of calcium tartrate is sufficient to eliminate the portion of malic acid beyond the tartaric acid stoichiometrically equivalent content.

Title: Plaster strips for joints between plaster panels - comprise fabric support coated with gypsum slurry contg. e.g. PVA, polyacrylate or cellulose deriv. adhesive
Inventor: FISCH JEAN-PAUL
IPC: E04F13/04
Filed: 1981-05-05
Abstract: Plaster strips are prepd. by known methods used for surgical plaster strips by coating a fabric support with an aq. gypsum slurry contg. one or more adhesives such as PVA, polyacrylates, cellulose ethers or other cellulose derivs. and opt. a wetting agent, followed by drying and heating. The novel feature is that the percentage and/or viscosity of the adhesive prod(s). is/are 20-200(50-150)% higher than those of surgical plaster strips. The strips are used for treating joints between plaster panels by wetting the strip, placing it on the joint where it adheres instantaneously, smoothing it with a painter knife, allowing it to harden for 2-4 mins. and then covering it with a finishing coating. This process is simpler and quicker than known methods of treating such joints. The strip is also more adherent.

Title: Fuel saving system for IC engine carburettor - includes use of reduced size main jet, with vacuum controlled by=pass providing additional fuel for acceleration
IPC: F02M7/133
Filed: 1981-08-25
Abstract: The system operates by using a main jet of reduced size in the carburettor whilst at the same time providing a bypass which allows additional fuel to be provided when the driver requires power to accelerate. An adapted tube (1) is attached to the joint between the inlet manifold and the carburettor. A flexible pipe (15) attached to a side arm (9) on this tube communicates the vacuum in the manifold to a pressure transducer (4). When the pressure falls below a partic. level, an electromagnetically operated jet (3) is opened, allowing additional fuel derived from a T-piece in the fuel line to be introduced via a side arm (8) and the tube (1) to the inlet manifold. The additional fuel may alternatively provide an injection of methanol and water instead of fuel derived from the normal supply line.

Patent FR-2495372-A1 (FR)
Inventor: GESZTI PAL OTTO
IPC: H01F27/245
Filed: 1981-11-27
Abstract: Energy systems which are now widespread have the characteristic that electrical installations and transformers having increasing unit power are used. The magnitude of the unit powers is determined by the mass and dimensions of the installations which can be supplied. The measures which were used in the past to increase the unit powers, specifically the incorporation of relatively large masses or the increased requirements, were to the detriment of the operating reliability. The invention offers a solution for increasing the unit powers which has no adverse effect at all on reliability. The transformer structure according to the invention is dismantled, in each case one unit, with the winding and the fluid insulating material, together with a part of the iron core, being arranged in a separate tank. During assembly, these are expediently connected, as a result of which the transformer with the split design can be assembled in each case into a larger unit.

Title: Electrode for direct current arc furnace - for scrap melting with conical tip controlling arc
IPC: H05B7/085
Filed: 1982-02-10
Abstract: Scrap metal is melted in a direct current arc furnace, with the electrode as cathode and the bath as anode. The end of the graphite electrode tapers to a conical point. The intensity of the electric field depends upon the shape of the electrode and is greatest at a point. This produces an arc acting vertically from the tip. Any tendency to move up the side of the electrode due to projections from the scrap metal is overcome by the electric field. With a conventional cylindrical electrode the arc starts vertically. It moves out to the corners, then tends to climb the sides of the electrode, becoming horizontal and extinguishing. This electrode configuration produces a quiet, steady arc, not likely to extinguish. It melts scrap more quickly than a conventional cylindrical electrode, and the point shape is maintained as it wears. This only occurs with direct current. It cannot work with three-phase alternating current due to the continual polarity changes.
