Patent FR-2217416-A1 (FR)
Title: Plant for growing selected yeasts and bacteria - for use in mfr. of fermented drinks
IPC: C12M1/26
Filed: 1973-02-09
Abstract: Plant comprises a multiplying tank connected to a feed tank through a pasteuriser with a regulating valve. The tank is first sterilised with steam and a small vol. of natural must, or diluted conc. must, is introduced through the pasteuriser. A pure, laboratory prepd. yeast culture is then introduced through a hydraulic closing device. The temp. is adjusted and sufficient oxygen introduced to cause movement in the fermenting mass; this movement may be assisted by an ultrasonic vibrator. After 24-28 hrs the ferment will have multiplied sufficiently and the tank is filled with must which has been treated in the pasteuriser. After another 24 hrs the ferments will have developed enough for use in seeding the musts that have been prepd. for making the fermented drinks. As the schizosaccharomyces, which transform sugar into alcohol and at the same time degrade maleic acid, multiply at a rate three or four times slower than the yeast normally present in must, there is great advantage in preventing the development of the latter by saturating the fermenting medium with large quantities of the pure culture prepd. as above.

Title: Improving combustion of fuel oils - by adding small amt of light hydrocarbon fuel
IPC: C10L1/04
Filed: 1973-02-13
Abstract: The combustion of fuel oils (esp. the incomplete combustion of heavy fuel oils for reducing gas prodn) is improved by adding a minor amt.

Title: Electric potentiometer sealed against gases - has linear resistive track making contact under pressure of outside slider
IPC: H01C10/00
Filed: 1973-08-20
Abstract: An electric potentiometer has a flat resistive track (1) mounted in a linear box having a control slider (3) projecting through the top. The slider presses on the outside of a flexible hermetic seal to make a contact between the inside surface directly underneath it and the track. The seal is extended to the edge of the box thus preventing gases or liquids from getting into the contact region. In the parts away from the slider the surfaces are kept apart to maintain the insulation by magnetic repulsion between the permanently magnetised strips (5) and (5') (6) and (6') which flank the track. The conducting surface can be a printed circuit.
