Patent FR-2678542-A1 (FR)
Inventor: GERARD DENIS
IPC: B29B11/00
Filed: 1991-07-01
Abstract: In order to heat thick-walled plastic preforms intended for the manufacture of containers by blowing or drawing-blowing, the preforms are irradiated by external infrared radiation transverse to the preforms and comprising a first wavelength band (B1) absorbed by the plastic and a second wavelength band (B2), separate from the first band, which second band is not absorbed by the plastic and reaching into the inner volume of the preforms: the wavelengths of the infrared radiation (12) located in the second band (B2) reaching into the said inner volume are modified in order to transform it into radiation (13) having wavelengths lying within the first band (B1); the modified-wavelength infrared radiation (13) is re-emitted in the direction of the wall (2) of the preform; and the modified-wavelength infrared radiation (13), being absorbed by the plastic in the vicinity of the internal surface (8), heats the plastic in the vicinity of the internal face (8) in such a manner that the temperature T1 there is greater than the temperature Te of the external face (10) of the said wall (2).

Patent FR-2666824-A1 (FR)
Title: Apparatus for eliminating metallic impurities from a fibre-transport path in preparation for spinning
Inventor: STEFAN SCHLICHTER
IPC: D01G23/08
Filed: 1991-09-17
Abstract: A path for the transport of fibre flocks has a branch point with a deviation means for the impurities, as well as a metal detector which acts on a control apparatus in such a way that the branch point causes a change in direction as a result of the passage of a metallic object in front of the detector. To simplify the installation of the apparatus and shorten the distance between the detector (11) and the deviation means (14) for the impurities, the metal detector (11), for example an induction coil, is installed above the deviation means (14), and the fibre flocks are transportable by gravity between the detector and the deviation means.

Title: Immunogenic recombinant strains of b. anthracis and immunogenic compositions containing same
Inventor: MOCK MICHELE
IPC: A61K39/07
Filed: 1992-04-30
Abstract: A recombinant strain of $i(B. anthracis) is characterized in that it can induce the production of protective antibodies against virulent strains of $i(B. anthracis) in a human or animal host, and characterized also by the mutation of the pXO1 plasmid of at least one given gene coding for a protein which causes a toxic effect of $i(B. anthracis), wherein said mutation leads to the deletion of all or part of said gene which codes for the protein causing the toxic effect, and to the insertion of a DNA cassette at said gene's deletion site in pXO1, whereby the strain thereby modified may be selected and a back mutation of the recombinant strain may be prevented, and wherein the gene thereby mutated is thereafter either unable to produce the protein causing the toxic effect for which it codes, or able to code for a truncated protein which has lost its toxic properties. The use of such a strain in immunogenic compositions is also described.
