Welding of two or more steel sheets (1, 2), at least one of which has a protective layer of a material with a low vaporization temperature, is carried out by directing a laser beam (L) on two overlapped flanges (1a, 2a) of the sheets (1, 2), which are clamped in position during welding by means of clamping devices (3). These clamping devices are able to hold the flanges to be welded (1a, 2a) in a ...

Two or more metal sheets (1, 2), at least one of which has a protective layer made of material having a low vaporization temperature, are welded to each other by means of a laser beam after that a gap (G1) has been provided between the sheets to enable the vapours of the protective material which are created during welding to escape. The gap (G1) is obtained by exploiting the elastic return of one...

The invention relates to a method and a system for paying a trading service for goods or services using cards on which there are codes that are covered by one or more blanking-out elements. The code is then transmitted to the trading service and the validity of the code and the credit associated with it are verified. The transaction and the payment are only validated if the code is valid and if th...

Carcasses (11) in an abattoir are cut in half by a rotating blade (2), which produces a clean cut, without slivers of bone. The blade may be round, hexagonal or star shaped. The arm (3) carrying the blade may also carry a sharpening stone.

A vibrating rate gyro structure machined in a plate of material and comprising a fixed part, a resonator, and a mechanical system connecting the resonator to the fixed part. The mechanical system comprises a first mobile mass part connected to one end of the resonator, a second mobile mass part (4) connected to the resonator and situated in the vicinity of the other end of the resonator, two flexi...

Integral capacitor manufacture on silicon substrate, involves depositing first and second electrodes and an intermediate dielectric layer. Before depositing the second electrode layer, the dielectric layer (2) undergoes exposure to plasma (5), generated in vacuum, under conditions of duration, energy and plasma density selected to avoid impairment of the dielectric layer.;

Three differently shaped metal bows (1,2,3) are pivotally joined to a central axle. A bicycle holding element (4,5) is also joined to the axle and can be adjusted in order to accommodate various models of bicycles. The lower bar of the bicycle is fixed with a movable bow (1) to the stand and the bicycle can now be safely tested or repaired. Functions like gears, brakes, running of wheels, conditio...

The invention concerns a method for making electronic micromodules including at least an antenna comprising the following steps: producing electronic circuits in the form of integrated circuits (7) from a first substrate wafer (6); producing antennae on said substrate wafer (1), in particular by etching strip conductors whereof the ends form bond sites; inserting an insulator between the two wafer...

The invention describes a process for cooling and if necessary calibrating elongated, especially continuously extruded objects (7) made of plastic as well as a cooling and calibrating device (5) for carrying out the process. With this the object (7) during its advancement in the longitudinal direction is exposed in consecutive regions (13 to 18; 86 to 89, 95 to 97) to a higher vacuum in each case ...

Container (12) slides or rolls on sheet metal plate (1) level with ground. This plate has left and right raised edges (5) which guide the plastic container wheels (13). Its bottom comprises an embossment which holds the wheels in a longitudinal position. A 9 degree inclination is given to the trolley to help its running. The container is inclined at 12 degrees to the horizontal and held in place b...

The trolley comprises a support bracket (11), a handlebar (4), a bag support hoop (3) and two locking tabs (8) for two clip supports (7,7bis). A lower horizontal mounting (10) holds the support (9a) for two wheel axles (15) and two plate supports (9b) for a sheet metal plate (1). The plate has two folded up sides (5), a folded up back (14) and two stops (6).;
