Title: Static filter rejecting parasitic electromagnetic radiation, for optical smoke detectors
Inventor: GERARD FELDMAN
IPC: G01J5/08
Filed: 1989-09-29
Abstract: The subject of the invention is the addition of a static filter system called "parasitic electromagnetic radiation rejector", to a receiver R which is part of a transmitter E/receiver R assembly, for progressive-opacity smoke detection. The internally reflecting rejector, in the shape of a truncated cone or truncated quadrilateral pyramid, concentrates the electromagnetic radiation reaching it axially from the transmitter E, whilst rejecting non-axial undesirable parasitic radiation. Referring to the figure, 1 is the rejector seen from the inside, 2 is the external view thereof, in the form of a template which is inscribed exactly in the casing 9. The photosensitive cell is represented at 4, the identical side platelets at 5-6, the top and bottom platelets at 7-8, the heel piece (shank) 3 providing centring in the direction of the height of the rejector with respect to the photosensitive cell of the receiver.

Title: Process for the production of a composite structure, strip of staples of composite material enabling the process to be implemented and process for the manufacture of the strip of staples
Inventor: MICHEL VIVES
IPC: C04B35/83
Filed: 1989-12-19
Abstract: A composite structure consisting of a fibrous reinforcing texture densified with a matrix is obtained by a process comprising the stages which consist in separately producing the constituent elements of the fibrous texture for reinforcing the structure, assembling the texture elements, and densifying the assembled texture, using the constituent material of the matrix, in which process the assembly of the texture elements is produced at least partially by stapling by means of staples made of composite material. The staples are available in the form of a strip of staples (10) of U-shaped cross-section, consisting of a fibrous reinforcing texture densified with a matrix and comprising weakened or precut parts (14, 15, 16, 18) which define breakage regions making it easier to separate the strip of staples into individual staples.

Abstract: The present invention concerns a process for identifying strains of Candida albicans and other generally pathogenic related strains belonging to the Candida and Torulopsis families. Said process, which makes use of a chromogenic substrate and does not involve the isolation of the strains to be identified, comprises the steps in which: (a) a sample of strains to be identified is put into contact with (i) at least one chromogenic substrate sensitive to at least one enzyme belonging to the family of the aminoamidases and aminopeptidases and (ii), to identify Candida albicans, at least one inhibitor selected from the family especially comprising the antibacterial and antifungal substances and their mixtures in the presence of sources of nitrogen, carbon and, where appropriate, oligo-elements; and (b) incubation is performed and then the kinetics of the cleavage of said substrate is observed for at least one hour through the coloration resulting from said cleavage. The preferred substrate for the specific identification of the strains of Candida albicans is taken from among H-L-Pro-pNA and their additions salts.
