Method for identifying an animal wherein a transponder is introduced in the animal. To prevent infection of the wound site together with the transponder a disinfectant is introduced. According to the invention this disinfectant is present in a bioabsorbable tablet and this tablet is introduced in line with the transponder.

The disclosure relates to an inductor (1) for induction welding of a pre-cut packaging material (9) in which the sealing region is restricted. The inductor (1) has, in a first plane (6), two equally wide conductors (3, 4), while the second conductor (4) is of considerably greater extent in a second plane (7) at right angles to the first plane (6).

- La présente invention concerne un procédé et une machine de marquage d'un câble électrique, comportant une âme conductrice, un revêtement isolant, et un vernis constitué d'une couche interne et d'une couche externe de couleurs contrastées, par ablation à l'aide d'un laser de la couche externe dudit vernis, réalisée à base de polytétrafluoroéthylène et ayant une épaisseur comprise entre 10 et 20 ...

A method of producing a marking on diamond, pearl, precious or semi-precious stone. For producing the marking, the region on the surface to be marked is irradiated with an ArF excimer laser whose output beam is passed through a mask which defines the marking. Identification or security marks may be created. The same process can be used to produce strong and durable extrusion dies having irregular ...

A ceramic composition for forming a ceramic dielectric body having a dielectric constant of less than about 4.2 and a TCE of less than about 4.0 ppm/c. The composition comprises a mixture of finely divided particles of 25-50 weight percent borosilicate glass and 50-75 weight percent high silica glass and 1-25 weight percent sufficient of crystalline ceramic material to inhibit the formation of cry...

Described is an improved process for fragmenting a biomaterial and isolating and recovering a component thereof. The preferred improved process includes the step of performing the fragmentation by nebulizing a liquid medium containing the bi- omaterial. A preferred process for fragmenting isolated DNA includes the ste p of nebulizing a fluid containing the DNA. This preferred process provides ra...

The semi-submersible floating apparatus for fish-farming and fishing in the open sea comprises an underwater body 2 which is always immersed and an exposed body 3 which is always outside the sea water and rigidly connected to the underwater body 2 by means of which it is totally supported; the bodies 2, 3 have a closed-ring configuration in plan view and define, inside their configuration, ample s...
