The invention makes it possible to weld two ceramic components by means of a laser beam without causing cracking in the components to be welded. The invention consists in preheating and heating the two components (4) by means of at least two side reflectors (7), for example halogen lamps. The inspection of the weld may be performed by means of a scanning electron microscope by observing the electr...

When controlling a travelling body so as to move forward the travelling body along the predetermined route, the distance and direction of deviation of a body of the travelling body from the predetermined route are measured, the above measured distance and direction of deviation of the body from the predetermined route are inputted as an observed value into an antecedent operation part in which the...

The electric lighting strip is made up from three elongated extruded metal sections. The sections have complementary cut outs to allow them to be assembled together. The first section (10) forms the base and is attached to the facade of the building. The edges of the base are sealed (8) to prevent entry of water. The base section houses the cabling and the electric fittings and equipment. The seco...

Production of recombinant antibody fragments Fab expressed in E. Coli, wherein the Fd portion is biotinylated in vivo following the fusion of the coding region of the antibody with that of a biotine receptor. The invention also concerns the utilisation of the bifunctional character of said biotinylated antibody fragments for the production of immunoassays and for developing antigen immunopurificat...

Prodn. of a product or semi-finished product from extruded material (3) by delivering the material as a continuous strand (41-4n) from an extrusion head (7) and by gravity depositing it onto a collection support (5). The support (5) is movable relative to the head (7) in a controlled way (11,13,14) so that the material, flat has not yet solidified can be deposited in any pattern. At each crossing...

Apparatus for quantizing compressed viedo data arranged in macroblocks calculates a quantizing parameter independently for each macroblock. The apparatus determines the relative coding complexity of respective macroblocks, and then determines which of the more complex macroblocks can withstand relatively severe quantization without significantly affecting image quality. This determination is made ...

The invention comprises cells or batteries 1 followed by a switch 2 which powers the control electronics 3 in order to supply, via the electrical wire 4 also used for supporting the pendulum, the laser diode 5 placed at the centre of the pendulum 6. The application of the said device allows an increase in the dowsing detection sensitivity.
