Patent FR-2299114-A1 (FR)
Title: Bonding metallic bodies using insert - which forms reducing atmos. preventing oxide formation
IPC: B23K20/02
Filed: 1975-02-03
Abstract: Metal bodies are bonded together by sandwiching an insert that forms a reducing atmos on bonding, between the bodies, applying pressure to the assembly to pressure bond the material with super-plastic flow at raised temps. and simultaneously with the application of pressure alternately heating and cooling the assembly through a temp. range above and below the transformation temps(s). of the metal until a permanent bond is formed. In bonding knurled pipes, boiler steel pipes, cast iron parts etc. Even if unbonded parts are left on the surface, the high temps. do not result in oxide formation because of the presence of the reducing atmos. The compression stress can therefore be lowered and the established bonding is a strong one.

Title: Overload protection switch or circuit breaker - using a self-restoring current limiting element in series with a fuse
IPC: H01H85/46
Filed: 1975-03-26
Abstract: Circuit breaker or protective switch device, consists of a self-restoring, current limiting element (I), connected in series with a meltable fuse. When the electric current actuates element (I), the fuse is driven into its switch-off or melting zone and interrupts the current. The pref. device uses an element (I) consisting of a metal which is liq. at room temp. or has a low m.pt. and is readily volatile, so that when a short circuit occurs, resistance heating converts the metal into vapour with a high electric resistance, thereby limiting the current; on cooling, the metal is restored to its state of good electric conductivity. When a low impedance short circuit current occurs, element (I) actuates the fuse. Element (I) pref. consists of Hg, Na, K, or a mixt. of Na + K, and is connected in series with a fuse (2) made e.g. of conventional wire.

Title: Electroradiographic device using heavy gas between electrodes - has added electron capturing light gas to sharpen recorded image
IPC: G03G15/22
Filed: 1975-04-28
Abstract: Electroradiographic device has two electrodes which must be connected to a continuous source of voltage, between which is located a heavy atomic gas, strongly absorbent to X-rays, to which a small amt. of another gas is added, the gas being kept at elevated pressure. The device has an insulating sheet arranged on the positive electrode. The gas added to the heavy gas is selected to have a high electron capture cross section and a relatively low m.wt. Advice of this type was described in DT 2258364, such that when an X-ray beam reaches the surface of the electrodes the gas between them is ionised and ions and electrons formed move towards the plates, the electrons setting up an image of electron charge on the negative plate according to the distribution of radiation intensity. The prior art device while effective in the plateau region of the Townsend curve of intensity distribution, in the avalanche region, due to the acceleration to which the electric field between the electrodes gives rise, the ions and electrons produce supplementary charge carriers which produce poor definition in the electronic image obtd. In the present invention the introduction of a gas with a high electron capture cross section reduces the tendency to produce supplementary charge carriers so that the image is sharpened.

Patent FR-2334224-A1 (FR)
Inventor: LEMAIGRE-VOREAUX PIERRE
IPC: H02H7/24
Filed: 1975-12-05
Abstract: The protection circuit has at least one discharge tube (5, 5'), which discharge tubes are connected between earth and a current conductor or which are connected between earth and in each case one current conductor (1, 2). In order effectively to protect sensitive components in the loads which are connected to the domestic installation, the connection of the discharge tube between earth and a current conductor is inserted downstream of the main switch (4) and upstream of the first load. In the event of overvoltages above a threshold value which is larger than temporary interference voltages in normal operation, but less than the maximum permissible voltage for the sensitive components, the discharge tubes (5, 5') trigger without any delay and short-circuit the current conductors via earth. The main switch (4) interrupts this short-circuit current and disconnects the discharge tubes and loads from the distribution line.
