Patent FR-2303851-A1 (FR)
Title: Controlled rate of industrial biochemical fermentation - by indirect evaporative cooling of fermenter to recover process heat
Inventor: COHEN GEORGES
IPC: C12M1/02
Filed: 1975-03-13
Abstract: A process is claimed for dissipating part and utilising the balance of heat generated in the exothermic stage of a fermentation process. The fermenter is cooled by an internal heat exchanger in the form of an evaporator supplied with a suitable, liquefied refrigerant, the evaporator pressure being automatically controlled as a function of the temp. in the fermenter. Refrigerant vapour leaving the evaporator is split into two fractions of which the first is subjected to a cooling process in a condenser from which liquefied refrigerant is recycled to the evaporator; the second fraction is cooled in a heat exchanger which transfers heat to a process operation on a product of the fermentation, this heat exchanger serving as a second condenser from which liquefied refrigerant is recycled to the evaporator. Pref. each vapour fraction is passed through a compressor before being condensed. The liquid refrigerant for vaporising in the evaporator is pref. a 2-5C hydrocarbon or a 1-4C halogenated hydrocarbon. Used for controlling the temp. and hence the fermentation rate in biochemical fermentation processes mfg. raw materials for the food industry, pharmaceutical and chemical industries, in partic. the prodn. of micro-organisms for the protein supplement of folder and foodstuffs. The control is automatic and precise so that risk of breakdown of the fermentation process is greatly reduced. Part of the heat to be dissipated is used in the mfg. process.

Title: Printed circuit board connector - has part on board allowing mounting of additional circuit elements
Filed: 1975-04-25
Abstract: The connector for printed circuit boards has two groups of connector strips. The female part is made of sprung metal contacts on an insulating strip and the male part of fixed pins on one side of such an insulator. The design is intended to allow mounting of additional indicator components etc., without greatly increasing the overall geometry. The female section may be mounted on the P.C.B. and has, to some degree, flexibility of movement and enables the design of a particularly economical mating male part. Strain on the soldered joints is minimised by making the joint in cut-outs in the insulating strip section.
