Patent FR-2314403-A1 (FR)
Title: Two stage hydropneumatic damper - with floating piston and telescopic housing to restrict stroke on rough ground
IPC: F16F9/06
Filed: 1976-03-08
Abstract: The vehicle is fitted with a two stage hydraulic damper which effectively shortens its stroke when subjected to large displacements. This is especially useful for aircraft landing on rough runways where they could distort their suspension. The damper has a floating piston (40) separating two gas fluid systems and the damper housing is in two telescopic sections (18, 21), with one of the sections sliding into the other to form a shorter damper, as required.

Title: Vehicle exterior removable deflector and sun-visor - has one piece elastic pressing held against inside of window frame
IPC: B60J1/20
Filed: 1976-06-30
Abstract: The removable deflector and sun-visor also acts as a rain guard, for fitting to a motor vehicle window. The front part forms the deflector and is extended to the rear by a surface acting as a lateral visor. It is supported on the outside surface and the front and top sections of the window frame. It is in one piece, and is held in position by its elasticity, bearing against the inner surfaces of the front and top frame sections.

Patent FR-2319222-A1 (FR)
Title: Tunable pumped dye laser - uses autocollimator grating to ensure coupling of pump signal to zero order refraction
IPC: H01S3/094
Filed: 1976-07-21
Abstract: The tunable dye laser operates with longitudinal coupling of the pump radiation ensuring a good matching of mode volumes of the induced laser ration in the resonator and in the pump. The wider tuning range leads to complete matching of the mode volumes with a narrow band emission. The cavity has one mirror and one reflection-diffraction grating. The grating constant is selected smaller than the shortest wavelength in the system which also contributes to a higher dispersion. This ensures narrow band laser emission. The optical resonator includes planar mirror (2), reflexion grating (3) and the active medium in the form of a dye-containing cuvette with Brewster windows (4). The grating is set to the cavity axis at an autocollimation angle which is a function of the grating constant and of the induced radiation wavelength. Pumping is provided by the light source (5).

Title: Indicating contents of rain gauge - is enabled by indicating height of flexibly mounted container
IPC: G01W1/14
Filed: 1976-09-16
Abstract: The level of water in a rain gauge is determined by reading the level against a scale or by using a float and indicator. Problems with these gauges are overcome by having a collector whose height varies as a function of water contained. An indicator permits reading at a distance. A rain gauge comprises a casing (2) mounted on a shaft for mounting on the ground. Water entering a cover (6) passes through holes (12) into a collector (14) supported by wire (26) mounted in a support frame (16) through springs (24) on a bar (22) to provide elastic suspension. A wire (38) attached to the supporting wire (26) is wound onto a pulley (36) whose shaft (32) rotates a pointer (8) on a scale to indicate water content.

Title: Testing and regulating gas producing rubbish dumps - using sonde gauges to prevent extraction rate drawing in air
IPC: E21B43/18
Filed: 1977-04-25
Abstract: A method of drawing gas from a rubbish dump on which there is a anaerobic fermentation, without introducing air in a quantity which would destroy its capacity to produce methane is carried out in a series of steps. Test shafts are bored, and gas is drawn off whilst maintaining a pressure which is low enough for the gas in the dump to flow into the boreholes being tested. At the time over a region near the test holes, other holes varying in depth and penetrating through the top covering layer into zones where fermentation is going on, are sunk for tubes fitted with pressure gauges. The magnitude of the first pressure at which the gasis extracted is then controlled continuously relatively to the pressure in the zones monitored by the sondes, so as to ensure that pressure does not fall below that of the atmosphere and air be drawn into the dump. On a basis of the tests carried out, a maximum extraction rate is decided. The tests are carried out on destroying the active bacteria by admitting oxygen.

Title: Storage stable valerian extracts - obtd. by dehydration of conventional valerian extracts
IPC: A61K36/00
Filed: 1977-11-30
Abstract: Stabilised valerian extracts contain 0.5 (0.1)% water, calculated on the wt. of the extract. In an example, 160g valerian extract (0.8% water) was diluted with 1000 ml benzene then dried for 3 days over a molecular sieve, to a water content of 0.1% (by reference to valepotriates). After 5 months storage the valepotriate content was 95% of the original value. Valerian extracts are known pharmaceutical agents, e.g. sedatives. The extracts are storage stable.
