Title: Volume regulated windscreen washer - with intake duct held at fixed position under lever by float
IPC: B60S1/48
Filed: 1975-04-28
Abstract: The windscreen washer is provided with an impulse generator to control the length of the washing action and hence to conserve washing fluid. In order to ensure that a constant vol. of fluid is delivered at every operation the intake duct is held at a fixed level below the fluid level in the reservoir by a flat, with the washer duct fitted with flexible hose. The intake of the washer pump is thus kept at a set value. The bottom of the reservoir is fitted with a level monitor comprising a temp. sensitive element whose temp. increases if the surface of the element is out of the water level. This switches off the pump action to protect the motor.

Title: Controlled cooling of steel bar for reinforcing concrete - to avoid formation of embrittling bainite, opt. with subsequent tempering
Inventor: DESALOS YVES
IPC: C21D9/52
Filed: 1976-06-15
Abstract: Reinforcing bar, for concrete, is prepd. using a controlled cooling step. in which the heat of rolling of the bars is used, and in which an accelerated cooling is effected to obtain a uniform structure over the cross section of the bars. The rate of cooling is slightly less than that leading to the formation of bainite, so as to obtain fine grains of ferrite-perlite and a significant quantity of fine perlite. The reheating associated with the transformation may be suppressed. Pref. the rate of cooling is high enough to obtain some martensite and opt. some bainite in the structure. Used for reinforcing concrete slab, pipes, posts, etc. The rods exhibit improved mechanical properties esp. elastic limit, together with improved ductibility.

Title: Temp. detector exposed to low ambient pressure - has gas-filled bubble which dilates under reduced pressure and is interposed between double coaxial tube housing
Inventor: TOCKERT CHRISTIAN JEAN
IPC: G01K1/08
Filed: 1976-11-16
Abstract: The detection appts. capable of fluctioning under conditions of differing pressure, comprises a sensitive element e.g a thermistor (11) in a housing with a thin gas-filled bubble (51) to detach the housing when the exterior pressure is reduced. The housing comprises two concentric tubes (39, 44) and the bubble is interposed between the ends of the tubes. The inner tube is held by the bubble and the outer tube frictionally engages a cap (29), such that when the force developed by the dilation of the bubble under reduced pressure, is greater than the frictional force, the simultaneous detachment of the external and internal tubes occurs, thus exposing the element to the external pressure. The bubble may be made from latex and filled with air.
