The inclinometer is of overall cylindrical form, made of back to back series of measuring modules (7) introduced into an inclinometer tube (3). Each module is linked to the adjacent modules by mechanical members (an articulated linkage with a longitudinal hole (17) through it) and by communication link (27) passing through the hole. The articulated linkage is a universal joint and the communicati...

The bar-code reader extracts information from bar-codes (3) printed on a discount coupon (4) and processes the information. The reader (2) delivers the signals from the bar-code scan to a computer (6), which performs the subtraction of the amount of the discount based on the data read from the bar-code. The computer has a storage (7) holding data concerning the coupon. The storage is physically re...

The invention is a grinding machine for ophthalmic glasses (14) of the type featuring a carriage (10) bearing a clamping axle in two parts (12A, 12B) between which a blank (14) of an ophthalmic glass is clamped and of the type equipped with a clamping device which axially acts upon at least one (12B) of the two parts (12A, 12B) of the clamping axle and features to that effect at least one geared m...

The invention relates to a process for valorizing a liquid acid effluent containing heavy metals, characterized in that it comprises: (i) removing said heavy metals from said effluent, whereby an aqueous saline solution is obtained, which contains at least 2 % by weight of salts; (ii) concentrating the saline aqueous solution obtained in step (i) by evaporation or electrodialysis so as to obtain a...

The device comprises a sensor (2) measuring the intensity of the ambient illumination at a chosen site. The intensity of light is compared with a reference signal in an electronic comparator unit (7). The sensor is at least one infra-red photo-diode centred on the wavelength around 950 nm. The sensor is directed toward the sky and is covered by a hemispherical enclosure (1) which is transparent to...

A method of accessing water from an aquifer which underlies an impervious stratum without contamination of the aquifer by polluted water from above the stratum by drilling a bore hole to the aquifer; comprises the steps of (a) drilling a first bore hole into, but not through the impervious stratum and a second bore hole of smaller diameter to the aquifer; (b) inserting therein a protective tube ...

A zero VOC aqueous coating composition comprising a halogen-free propylene/ alpha -olefin copolymer having an alpha , beta -unsaturated dicarboxylic acid or anhydride grafted thereon, a base, and a water-dispersible resin containing at least two epoxy groups is applied to a plastics substrate comprising a propylene polymer. The dried coating promotes adhesion of a subsequent coating to the surfac...

A coder assembles bursts of blocks of image data (eg transform coded coefficients) and associated overhead data into a sequence of data which are then transmitted. Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory stores (21)(22). The blocks of transform coded coefficients have a 'last coefficient' flag accompanying the last coefficient, and t...

The unit to assemble two elements (12,14) consists of a finger forming a hook (30) carried by one of the elements (12,14) which is designed to cooperate with a rigid anchorage (32) of a form complementary to that of the hook (30) carried on the other element (14,12). The hook is elastically deformable in the disengaging direction of the anchorage (32) and is characterised in that it consists of a ...

The system has a surface(3) designed to receive an article(2) fitted with a magnetic ant-theft element(2b). The system has a magnetic field generator(8,9,10,11,12) which has two axial ends each forming a magnetic pole end adjacent to the surface(3), so as to generate a magnetic filed between the two magnetic pole ends near to the surface(3) for de-activation of the element(2b). The magnetic field ...
