Patent FR-2237297-A1 (FR)
Title: Differential action switch - has S-shaped bimetallic strip with a heating element on each limb
IPC: H01H61/08
Filed: 1973-07-09
Abstract: The bimetallic strip may be S-shaped. A change-over switch (T) is operated thermo-mechanically by current in a heating element (R1) on one limb of the bimetal strip (4) which expands to push an actuating lever (ST). When (R1) is disconnected and the second heating element (R2) on the other limb, is energised, contraction of (4) releases the switch rapidly. Cyclic operation occurs with small on/off time ratio. In variants the bimetal strip operates/releases two change-over switches simultaneously or successively with adjustable delay. The single-switch may be for a flashing light system, and of the two switch device for a heating and lighting system.

Title: Tool for extraction of hollow cotter pins - has split tube inserted through pin to locking position and withdrawn
Inventor: FOYARD LOUIS-CLAUDE
IPC: B25B27/08
Filed: 1974-06-05
Abstract: The tool for the extraction of hollow cotter pins is esp. applicable to pins accessible from one side only, and constitutes a hollow split tube with an externally toothed head which is inserted fully into the pin and then withdrawn with the pin using screw-jack.

Title: Continuous prodn of curds for cheese making - without pre-concn of milk, using hot whey to coagulate acidified milk
IPC: A23C19/05
Filed: 1974-11-13
Abstract: Process for prepg. curds for cheese making, esp. from the milk of cows, goats, ewes and buffaloes, comprise (i) seeding the milk with lactic enzymes to obtain a pH of 4.6-6.6; (ii) cooling to 2 degrees - 25 degrees C; (iii) adding rennet and this to act on the cold milk for as long as required for the type of cheese being made; (iv) reheating by adding warm whey so as to cause rapid coagulation, pref. the temp. of the whey being such that the temp. of the mixt. is 30-50 degrees C. The hot whey can be a recycled whey from this or some other cheese-making process, or is reconstituted from a dried whey and may be more or less conc. in soluble milk solids than a normal whey. Continuous cheese making is possible without pre-concn. of the milk. By using whey instead of hot water for coagulation, the soluble solids content of the curds is improved. Proteins in the hot whey are largely denatured and are retained in the curds.

Title: Weft insertion mechanism on fixed yarn reserve looms - positioned to avoid loading of sley, and fully lubricated
IPC: D03D47/27
Filed: 1975-06-23
Abstract: An arrangement for controlling the weft lance on looms with fixed reserves of weft yarn, has a rotating shaft on which the sley pivots and on which there are two profiled discs with complementary contours followed by two rollers.

Title: Humidity control by electro:osmosis with hygrometer - for slow drying of dwelling walls without deterioration
IPC: E04B1/70
Filed: 1975-07-08
Abstract: Device for allowing control of humidity of a given place operates on Reuss's principle. It includers a hygrometer with electrical contacts which establishes the circuit either at the upper electrodes, which are supplied with a continuous current, or at the lower electrodes, which drain the electricity produced by the wall itself.

Title: Tension leveller for continuous metal strip - has feedback applied through electrohydraulic converter to tension motor epicyclically geared to drive rolls
IPC: B21D1/05
Filed: 1976-07-12
Abstract: A tension levelling machine for the continuous flattening of metal strip such as aluminium, consists of a set of entry rolls, a work station and a set of exit rolls. The main drive is taken from the motor and a system of differential and epicyclic gears to the exit roll. A hydraulic pump with variable output is connected to a hydraulic motor and provides a conventional speed control. The gear drives a shaft through a clutch to the shaft driving the inlet roll. The inlet and exit rolls are connected by epicyclic gear trains. Tension is provided by hydraulic motors which are driven by the electrohydraulic converter. The output is governed by the pressure measuring roll and the hydraulic pump driven itself by the main motor. An auxiliary pump provides tension when the machine is stopped.
