Title: Liquid-cooled mould for continuous casting of steel billets in slab form
Inventor: ARVEDI GIOVANNI
IPC: B22D11/04
Filed: 1991-09-23
Abstract: The invention concerns a liquid-cooled plate mold with adjustable width for the continuous casting of billets from steel in the form of slabs, particularly for a slab thickness of less than 100 mm. The shape-imparting broad side plates (1) and narrow side plates (2) of the ingot mold are constructed in the direction of their transverse extension so as to increase in cross section for the billet, while the narrow side plates (2) extend substantially parallel to one another along the height of the ingot mold. Further, the broad side plates (1) are constructed so as to be concave at least in a region (3) of smallest slab width in such a way that, in cross section, the apex height (13) of the ingot mold wall forming a curve has a determined height relative to a rectangle inserted in the drawing. The shape of the billet side plates at the billet outlet end (5) corresponds to the billet format to be produced.

Title: Plant promoter involved in controlling lipid biosynthesis in seeds
Inventor: DE SILVA JACQUELINE
IPC: A01H5/10
Filed: 1992-04-08
Abstract: A new seed-specific plant promoter is provided, capable of expressing a gene placed under control of said promoter before or during fatty acid or lipid biosynthesis in plant cells. In nature it occurs in the acyl carrier protein (ACP) gene. This opens the possibility of modifying the fatty acid synthesis in plants, which may result in changing the triacyglycerol composition of oil-containing seeds. Another option is the production of a desired protein in plants, either to improve the nutritional value of the seeds, or for the production of specific proteins that can be isolated from the fruits of plants.

Title: Scroll compressor
Inventor: INAGAKI MITSUO
IPC: F04C18/02
Filed: 1994-10-19
Abstract: A self-rotation blocking mechanism in a scroll compressor having a movable scroll member and fixed scroll member fixed to a casing. The mechanism is constructed of circumferentially spaced opposing pairs of pins 9 and 10, which are connected to an end plate 12 of the movable scroll member 2 and a faced end wall of the casing 4, respectively, and which are in a side-by-side contacting relationship. The circumferential arrangement of the pins is such that, at every angular position of the movable scroll member, there exists at least one pair of the pins which generates a force in a direction opposite to a self-rotating torque applied to the movable scroll member caused by the compression reaction force.      A locally concentrated arrangement of the pairs of the pins for generating such a force can be employed at the angular position which produces a larger value of self-rotating torque. Furthermore, the diameters of the pins are such that one half of the sum of the diameters is equal to or smaller than the radius of the orbital movement of the movable scroll member.

Filed: 1993-10-30
Abstract: Un filtre à onde acoustique de surface (SAW), ou d'autres filtres d'amplificateur FI groupés, est suivi d'une chaîne d'amplificateurs FI et d'un second détecteur ménagés dans les limites d'un circuit intégré monolithique. La chaîne d'amplificateurs FI comprend trois amplificateurs différentiels, couplés à un émetteur, dont chacun présente un gain de tension pouvant être multiplé par vingt environ, et montés en cascade l'un après l'autre. Il est possible de commander automatiquement le gain de tension des deux premiers amplificateurs différentiels couplés à un émetteur. Des amplificateurs à collecteur commun sont utilisés pour tamponner l'application des signaux de sortie équilibrés provenant de chacun des amplificateurs différentiels couplés à un émetteur à l'amplificateur différentiel successif ou un second détecteur (DET). Des réponses de courant équilibrées aux potentiels à polarisation directe sur lesquels les signaux équilibrés fournis au second détecteur sont respectivement superposés sont extraites par un filtrage passe-bas (LPF) sur-puce et n'utilisant pas de condensateurs de dérivation FI hors puce. Ces réponses de courant équilibrées sont réalimentées aux émetteurs des transistors dans les amplificateurs (Q68, Q69) à collecteur commun utilisés pour coupler le premier amplificateur différentiel couplé à un émetteur et à régulation de gain dans la chaîne d'amplificateurs FI, au second amplificateur différentiel à régulation de gain dans la chaîne d'amplificateurs FI. Ceci complète une boucle de réaction à couplage direct afin de réduire les différences entre les potentiels de polarisation directe sur lesquels les signaux équilibrés fournis au second détecteur sont respectivement superposés.
