Patent FR-2240141-A1 (FR)
Title: Deep-water storage tank for hydrocarbons - easily towed and submerged on site, with pressure equilibrium
IPC: B65D88/78
Filed: 1973-08-07
Abstract: A submarine reservoir for liquids can be deposited on the seabed at a speed reconcilable with its design characteristics, by means of compensating ballast weights and a recoverable buoyancy vessel released by an explosive coupling. The reservoir is maintained at equal pressure whatever the depth reached, and its stability on the bottom is ensured by the replacement once for all time, of part of the hydrocarbons stored, by seawater; the water reservoir acting as a ballast tank during immersion and serving as an oil separating vessel to clarify the water each time the reservoir is refilled. Fills the need for a submersible reservoir for depths of 100 metres and more. Easily transported, pressure automatically balanced during descent.

IPC: D06C23/00
Filed: 1974-06-04
Abstract: Designed for woven or carpeting materials, such as for use in vehicles, an embossing die or roller applies local heat and pressure into the material thickness to impose a pattern, the heat giving a partial melting and colouration to the synthetic fibres, in a continuous or intermittent process. This gives a three-dimensional patterned effect, the floor covering being stable and not creasing underfoot.
Patent FR-2273780-A1 (FR)
Title: Ceramic glazing of porous concrete - providing sealing properties and allowing rapid simultaneous application
IPC: C04B41/50
Filed: 1974-06-05
Abstract: Ceramic glaze is applied to porous concrete by applying an intermediate layer of slip which reduces tension between the concrete and ceramic glaze during firing and which levels the surface of the concrete so that the glaze does not sink into the concrete. The slip may be diluted with adhesive material, e.g. sodium silicate, to allow it to adhere prior to firing. The adhesive material may also be added to the glaze for the same purpose. A decorative effect may be obtained by juxtaposing or superimposing different glazes.

Title: Laser sound detector system with source generating light beam - has reflecting means at distance from source
IPC: G02F2/00
Filed: 1975-01-30
Abstract: The light from the light beam which is generated by a laser is reflected after being modulated by sound waves which are made to interact with it. The modulated reflected light is then fixed or demodulated. Recording means connected to the detector facilities can be used to record a quantity representing the sound, and converter equipment connected to the detector facilities can convert the sound-modulated light into an audible tone. Modulation of the light by sound can include amplitude modulation. The apparatus is also suitable for use as a penetrating alarm. The alarm can be triggered off as a result of an invisible light beam being broken.
