Title: Solid state thin-layer laser - has active laser materials and substrate forming resonator space at angular setting for beam reversal
IPC: H01S3/063
Filed: 1975-02-17
Abstract: The solid state thin layer laser has the active material deposited on a substrate, as well as selection means for preset modes in connection with a waveguide. The active material and the substrate form together the resonator space of the latter, and the end surfaces of the active material with the adjacent end surfaces of the substrate are ground to such an angle that the impinging light beams are deflected into the substrate. The refractive index of the active material is higher than all adjacent refractive indices. The laser assembly is formed as a hybrid integrated element. Preferably the substrate surfaces, on which impinge the light beams to be amplified, are obliquely ground and provided at the ground surfaces with resonator mirrors.

Title: Solar energy panel support foot - forms rigid polygon with panel and is pivotal about corner to vary panel inclination
IPC: F24J2/52
Filed: 1975-03-26
Abstract: The polygonal form support (0, 1, 2, 3, 4) has two adjacent sides (01, 04) of unequal length, either of which may rest on the ground, by pivoting the arrangement about the junction (0). The polygon is completed by the solar panel (5) itself. A support at each end of the panel thus allows the whole panel to be tilted as required. Recommended angles (a, b) are 25 deg. in summer and 51 deg. in winter. If desired, the polygon may have more sides so that more than two angles of tilt are available.
Patent FR-2313591-A1 (FR)
Title: Bearing for slowly rotating heavy load - suitable for rotating ladles handling molten metal in foundaries
IPC: F16C17/03
Filed: 1975-06-04
Abstract: The ladle which is used for pouring molten metal in foundries is provided with a metal tyre at each end. Each tyre is supported on two bearings mounted on a base forming part of a trolley. The bearing is in the form of a squat cylinder housing a ring. The ring is pressed against the tyre by the pressure of the lubricating grease in the reservoir. A sealing ring prevents loss of grease through the clearance between ring and cylinder. This type of grease lubricating bearing spreads the load over the surface of the tyre and reduces wear when compared with roller type bearings.

Title: Drainage ditch excavator with parallel cutting discs - has spoil hopper and elevating hoist receiving material from knife and scraper between discs
IPC: E02F3/18
Filed: 1975-07-03
Abstract: The drainage ditch excavator consists of a pair of vertical parallel cutting discs (14) supported on an arm (13) which moves on an axis connecting it to the chassis. This arm is controlled by a hydraulic jack. The excavator has a pair of shoes (17) which regulate the cutting depth and are also supported by the arm. A knife (20) is positioned between the cutting discs and a scraper (21) moves the material which it cuts into a channel (22) linked to a hoist (23). This empties into a hopper (10) supported on the axle (8) of the excavator. This avoids mounds of material being left at the side of the ditch.

Title: Determining sea-bed contours - by adding distances sepg. submerged instrument from surface and from sea-bed, calculated from pressures and acoustic measurements
Inventor: MICHEL JEAN-LOUIS
IPC: G01C13/00
Filed: 1977-02-11
Abstract: A method of determining the contour of the sea-bed comprises submerging an instrument in the sea a short distance above the sea-bed, calculating its depth in the relation to a reference plane at the surface from the press. measured at the level of the instrument, measuring its height in relation to the sea-bed by an acoustic probe on the instrument and adding the two measurements. The method is used for cartography of the sea-bed. It is important to know with precision the form of the sea-bed for the development of off-shoe petroleum and mineral mining. The method avoids the problems associated with the use of an acoustic sounding appts. on the surface e.g. the difficulty of surveying every point with an acoustic beam when the depths of immersion are great and variations in the velocity of sound; the use of a submerged instrument carrying an emitter-receiver of acoustic waves moved from point to point on the sea bed, e.g. the time taken and lack of precision.
