Patent FR-2283303-A1 (FR)
Title: Shut-off valve for borehole - blow-out arrester
IPC: E21B34/04
Filed: 1974-08-30
Abstract: In a shut-off valve intended to be lowered on a pipe string into a blow-out valve shaft in the outlet of a borehole, provided in known manner, with (i) a housing with a channel passing through it and a displaceable valve body which opens this channel in a first position and closes it in a second, (ii) a pressure-sensitive operating element connected to a pressure pipe for displacing the valve body to the first position and a closure element which displaces the valve body to the second position on reduction of the pressure in the pressure pipe, the improvement whereby the operating element is exposed to the hydrostatic pressure of the fluid surrounding the housing in order to compensate for the hydrostatic pressure of the fluid in the pressure pipe. More especially, the valve body is constructed as a pivotable ball with a passageway opening which can be brought into line with the channel in the housing. Overcomes problems which exist in known shut-off valves, inter alia the high pressure which must be exerted on the operating piston when the valve is held open to overcome the hydrostatic pressure of the medium surrounding the valve, and the fact that if a cable passing through the valve breaks above the valve, this cannot be shut because the cable cannot be withdrawn.
Patent FR-2291412-A1 (FR)
Title: Automobile disc brake with radially movable actuator - has leaf spring holding actuator against stops formed by threaded studs

Each stirrer is powered independently from the carriage to move in a circular path in a vertical plane, and the speed of movement of the carriage and the stirrers can be adjusted so that the blades describe loops varying from generally circular to a generally undulating path. The appts. is esp. useful in cheese processing and gives thorough agitation.
Patent FR-2300151-A1 (FR)
Title: Stop motion for detecting roving breaks - includes switch for automatic start up on resetting stop motion after a break
IPC: D01G31/00
Filed: 1975-02-10
Abstract: A stop motion for a roving includes a pivoted guide channel through which the roving passes and which in held in an operative position by a pivoted support and the tension in the roving. When the roving breaks the support falls and the guide channel pivots so that pref. its near end actuates a micro-switch to shut down the loom. In the position in which the support holds the guide channel in the operative position, the support actuates a second micro-switch which ensures continued operation of the machine. When the stop-motion is reset after a breakage and the support is pivoted to hold the guide channel in its operative position, the support automatically actuates the second micro-switch to re-start the machine.

Title: Thermo-coagulable lactoprotein for incorporation into cheese - recovered by flocculating lactoserum, centrifuging then homogenising
Inventor: MIGNOT BERNARD MICHEL
IPC: A23C9/15
Filed: 1975-02-19
Abstract: Incorporating thermocoagulable proteins of lactoserum into cheese comprises the following stages. (a) flocculation of the lactoproteins under slight agitation at 90-100 degrees and pH 5.9-6.1; (b) concn. by centrifugation; (c) homogenisation of the concentrate by a mechanical treatment below 60 degrees C to obtain a colloidal prod. having a pseudosolubility >40% (defined as the amt. remaining in suspension after centrifuging cold for 11 mins); and (d) incorporation of the colloidal protein milk into the cheese making milk just before moulding. Also a colloidal suspension of lactoproteins is prepd. by the above process (a) to (e) and also the cheese prods. obtd. by stage (d). According to a previous process, the denatured protein is recovered as a protein milk concentrate by centrifuging. The above is an improvement giving satisfactory cheese; previously it has been difficult to recover the lactoprotein as it gives the cheese a coarse texture and bad taste.

A deflector-plate (7) partly closes the outlet to a tunnel-shaped opening (8). The mown grass cut by the rotor (1) is driven by the air current and guided by means of the deflector -plate (7) to the turbine (5), and chopped up again by the cutting edges (6). Part of the mown grass is discharged through the hole (8) and the rest is conveyed by the cir-current produced by the pack-parts (3).

Title: Consumption level sensitive electronic control relay - has binary and memory circuits controlling load circuit switching
IPC: H02J3/14
Filed: 1975-07-08
Abstract: The relay, for general control purposes, is sensitive to some preset consumption level. The actual switching is part of a circuit block designed such that the system open circuits when the current drawn during some predetermined time period exceeds some given level, the measurement being made continuously during this period. Similarly the load is reconnected if it falls below the level. Measurement of load is by measurement of a series of pulses generated in proportion to the power consumption and a further series of constant pulses proportional to the preset load level. Two binary counters, a comparator and a memory circuit provide the actual relay control.

Title: Aircraft structure strain gauge - has deformable part in form of arc of circle between fixed bases and piezoresistive elements to measure deformation
Inventor: BEAUFRONT JACQUES
IPC: G01L1/22
Filed: 1975-11-14
