Patent FR-2132249-A1 (FR)
IPC: G11C13/04
Filed: 1972-03-30
Abstract: The present invention is directed to a method and apparatus for recording information on a holographic storage medium which information is presented in an information mask characterized by projecting a coherent light beam, which has been polarized in one direction, through a mask which changes the direction of polarization of discrete portions of the light beam which is subsequently divided into a plurality of light beams by a mosaic of lens. The plurality of light beams are projected through the information mask, which modulates the beam with information contained in the mask, and onto the holographic storage medium where a reference beam is superimposed therewith to record the information. The polarization mask is provided with statistically distributed raster of apertures so that a portion of the light beam passing through the material of the mask has its direction of polarization rotated relative to the direction of polarization of the other portion which passes through the apertures. The angle between the directions of polarization of the two portion of the light beam is in either a range of 80 DEG  to 100 DEG  and preferably 90 DEG  or a range of 170 DEG  to 190 DEG  and preferably 180 DEG .

Title: Cobalt recovery - from an ammonium carbonate solution contg nickel and cobalt
IPC: C22B23/00
Filed: 1972-05-10
Abstract: The soln. is treated by addn. of sulphurating agent followed by addn. of a gas contg. O2. The quantity of NiSO4 which is pptd. with the CoSO4 is restricted so that the ppt. is enriched in Co and the mother-liquor in NiSO4. Alternatively, the ammoniacal wash may be thickened to increase the quantity of solids followed by treatment with a gas contg. O2. This results in selective dissolution of NiSO4 from the ppt. so that it returns to the mother liquor.

Title: Composite cellular plastic panels - of honeycomb type with light weight and high strength
IPC: E04C2/36
Filed: 1972-08-24
Abstract: The panel consists of a core placed between surface layers, the core consisting of alternate strips of plane and corrugated plastic material reinforced with fibres, the crests of the corrugations being in contact with the adjacent plane strips so as to delimit cells whose edges are formed by the parallel surface layers of the panel, which are themselves formed from fibre reinforced plastic material adhesively bonded to the core. The panels are very rigid but light in weight since less material is used to form cells larger than those previously used in honeycomb panels. The distance between the plane sheets and the crests of the corrugations may vary between 3.048 and 10.16cm., the crests being pref. in circular arc form of radius equal to 25-35% of the cell height, and being joined by inclined planes at 60 degrees-90 degrees C. The thickness of the core sheets is pref. 0.0635-0.0889 cm. and that of the surface sheets 1/20 to 1/40 of the cell height. The assembly may be of glass fibre reinforced polyester resin.

Title: Fork lift truck with weighing device - has conventional yard arm weighing device fitted to loading platform
IPC: B60P5/00
Filed: 1973-05-16
Abstract: Fork lift trucks often carry goods which have to be weighed. It is traditional to weigh truck and load on a stationary scale and to subtract the truck weight. This needs two men and moving to a heavy capacity scale, so the invention covers a weighing device fitted to the truck loading platform. The platform is connected to the weighing mechanism via a fork arrangement and an indicator for the weight is placed in easy view of the drives. The weighing device is of the traditional yard arm type, adjustments being easily made by the driver. Platform and weighing mechanism can be locked.

Title: Power generator using static water pressure - uses an aerated column of water to cause upward flow
IPC: F03B17/00
Filed: 1974-03-26
Abstract: The device consists of a hollow cylinder (1) open at each end which is immersed in water. The lower portion (2) has a larger diameter and is joined to the cylinder (1) by the cone (3). A duct (5) at the side of the cylinder supplies air to a turbo compressor (7) which delivers air through the opening (6) into the cylinder (1). The mixture of air and water rises upwards to the water surface and in doing so it drives the turbines (13) (14) and (15) which, in turn, drive the generators (10) (11) and (12). According to the invention, the power thus generated is greater than that required to drive the turbo-compressor.

Patent FR-2273202-A1 (FR)
Title: Two speed drive for IC engine coolant pump - has planetary gear released from satellite carrier at set engine speed
IPC: F01P7/04
Filed: 1974-05-30
Abstract: An automatic speed change is achieved by interposing an epicyclic gear train (1, 3, 5, 6) between the V belt input drive (2) and the output pump drive shaft (8). The speed change occurs when weights (23) push a spring (27) loaded arm over the top dead centre position of the spring, due to centrifugal force. This action suddenly releases the pressure of brake pads (32) on the planet wheel (6) whic is then free to rotate. Rotation of the planet wheel causes brake shoes (34) to expand against the drum (19) and the output shaft then rotates at the same speed as the input pulley. Prior to the action, the epicyclic gear causes the output shaft to rotate at twice the speed of the input pulley.
