Title: Heptaminol salts - with analeptic and sedative action
IPC: A61K31/205
Filed: 1970-07-30
Abstract: The 5-ethyl-5-phenylbarbiturate, 2-pyrrolidone-5-carboxylate, mandelate and tropate salts of heptaminol (6-amino-2-methyl-2-heptanol) have analeptic activity for treatment of senility, cerebral angiosclerosis, depression, fatigue.

Patent FR-2104922-A1 (FR)
Title: Nuclear reactor closure - sealing passage at core compartment outlet piped to refrigerant supply
IPC: G21C13/073
Filed: 1970-09-04
Abstract: In fast neutron reactors using liquid sodium as the cooling agent for the core, it is essential to prevent leakage of sodium from the core compartment after it has passed through the core. To this end, a core compartment closure presents two, coaxial ridges to seat on a shoulder at the mouth of the core compartment, forming an annular passage between the ridges which is piped to receive sodium at full pressure from the upstream side of the core; since this full pressure is the sodium pressure in the core compartment after passing through the core, any leakage will tend to be from the passage into the compartment.

Title: Protecting steel against corrosive gas - esp fluorine arising from uranium hexafluoride
IPC: C23C4/08
Filed: 1973-07-02
Abstract: Steel is protected from corrosive gases esp. F2 by (a) hot-spraying a coating of Al on the steel, (b) mechanical blasting to obtain a smooth surface and close the pores in the Al, (c) heat treating the coated part below the temp. where diffusion of the Fe-Al occurs. The Al coating is pref. 30-300 mu thick, shot-blasted with rounded particles, esp. of Al with mean dia. 1mm, and heat-treated 2 hours at 450 degrees C. This method prevents the reaction of the steel with uranium hexafluoride utilised in isotope sepn.; this reaction produces solid, non-adherent fluorides which interfere with the appts. and cause loss of uranium in addn. to steel corrosion.
Patent FR-2238096-A1 (FR)
Title: Eccentric split piston sealing ring - greatest thickness is opposite gap and thickness reduces uniformly
IPC: F16J9/00
Filed: 1973-07-18

The inner and the outer diameters are formed eccentrically so that its thickness is greatest opposite the split and reduces uniformly to its smallest value at the cut. The grooves in the piston are also machined to match and, when more than one ring is used, the eccentricity is spaced equally around the piston.

Title: Leak detection device for a reservoir - measures pressure difference between hydraulic measuring pressures
IPC: G01M3/32
Filed: 1974-03-15
Abstract: The detection of leaks in reservoirs is determined from a measurement of hydraulic pressure to which the reservoir is submitted. The reservoir is also submitted to a different but constant hydraulic pressure and the volume variation of the contents is detected. The variation of volume of a reservoir is detected by a visible level vertical tube connected to the reservoir. The tube is also connected to an adjustable regulated inert gas supply in order to supply the different constant pressures required by a piston sliding in the vertical tube and supporting weights corresponding to the pressure. The variation of volume is observed on a transparent level tube connected to the vertical tube and is detected by a differential pressure detector.

Title: Battery charger with variable input voltage - is adjusted to allow max. current in rectifier transformer
IPC: H02J7/12
Filed: 1974-08-02
Abstract: If the current to be supplied from the mains is limited, the output voltage of the rectifier transformer can be reduced during the time the battery is fully charged. It is only restored to its original value when the battery is already partly charged and requires a higher input voltage. Current is sent through to the battery when the voltage differential permits a charging pulse. Pulses predominate during the positive wave periods.
