Abstract: Un matériau de renforcement contenant des fibres et un procédé de fabrication d'un tel matériau, ainsi que l'utilisation dudit matériau de renforcement pour la production de matériaux composites sont décrits. Le matériau de renforcement comprend une répartition homogène de fibres de carbone et de fibres de verre selon un rapport en poids compris entre 1/99 et 99/1, une silice colloïdale anionique et hydrophobe en une quantité d'environ 5 à 20 % en poids du poids total des fibres étant ajoutée aux fibres comme enduit externe. En outre, le matériau de renforcement contient environ 5 à 20 % en poids de talc, de préférence de la pierre de savon, sur la base du poids total des fibres. Le matériau de renforcement est produit par dispersion à sec de faisceaux de fibres de carbone sous l'action d'un cisaillement pendant environ 10 à 30 minutes, l'adjonction de silice s'effectuant au fur et à mesure. Les fibres de verre sont ajoutées au mélange de fibres de carbone et de silice et dispersées à sec conjointement avec lui pour former un mélange sensiblement homogène, puis du talc cationique, constitué de préférence par de la pierre de savon, est réparti dans le mélange. Le matériau de renforcement fini peut être utilisé pour la production de matériaux composites renforcés par fibres.

Title: Procede et vaccin sous-unitaires contre la dysenterie porcine
Inventor: JOENS LYNN A
IPC: C07K14/195
Filed: 1989-09-13
Abstract: L'invention concerne un procédé de préparation d'un vaccin sous-unitaire contre la dysenterie porcine. Le vaccin sous-unitaire de la dysenterie porcine se compose d'un matériau antigénique récolté de la surface d'un spirochète anaérobie, le Tréponéma hyodysenteriae. Les cellules bactériennes, développées antérieurement dans un grand volume (5-7 litres) dans une cuve de fermentation sont récoltées par centrifugation et lavées vigoureusement dans une saumure tamponnée au phosphate. Les cellules bactériennes sont ensuite extraites lors d'une seconde centrifugation et le supernageant est retenu. Le supernageant contient un extrait de sel constitué du matériau antigénique utilisé dans le vaccin. Après récupération de l'extrait de sel, ce dernier est concentré 100 fois. L'extrait de sel s'est révélé être immunogénique chez les porcs. Des porcs de cinq à six semaines sont hyperimmunisés par voie intramusculaire (IM) avec l'extrait de sel. Les porcs vaccinés avec cet extrait de sel sont protégés contre l'infection provoquée par Tréponéma Hyodysenteriae.

Abstract: The earth ring (8) carries the lunar disc (9) which pivots in a hollow of the surface (8a). At its outer periphery, it has a toothing (17) for driving by the final gear (15) of the step-by-step transmission gear train (15, 24, 12). The drive gear (12) is moved by one step per day from the day wheel. The pinion (20) of the lunar disc (9) is in engagement with the outer toothing (22) which is normally fixed but may be displaced by means of the correction device controlled by the rod (30) when it rotates in a predetermined direction. The same correction device also permits action on the transmission train (12, 14, 15, 17). The rod (30) is then driven in a direction opposite to the abovementioned direction, which displaces the reverser (36) and permits the correction of the position of the lunar disc (9) relative to the earth ring (8), the latter normally effecting one revolution on itself over twelve months and the lunar disc (9) effecting a complete revolution over approximately 29.5 days. <IMAGE>

Abstract: In a semiconductor layer which is for reflecting an optical beam and comprises a plurality of film pairs of narrow and wide band gap semiconductor films (21, 22) having a refractive index difference and narrower and wider band gaps, an intermediate semiconductor film (31) is interposed between the narrow and the wide band gap semiconductor films of each film pair and is made to have an intermediate film band gap which is varied so as to be equal to the narrower and the wider band gaps at its interfaces contiguous to the narrow and the wide band gap semiconductor films. The narrow band gap semiconductor film and a portion adjacent thereto in the intermediate semiconductor film are called a first composite layer and given a first total thickness which is approximately equal to a quarter of a first wavelength had by the optical beam in the first composite layer. The wide band gap semiconductor film and a remaining portion adjacent thereto in the intermediate semiconductor film are called a second composite layer and given a second total thickness which is approximately equal to a quarter of a second wavelength had by the optical beam in the second composite layer. Preferably, the intermediate semiconductor film should have a film thickness which is substantially equal to a width which a potential barrier has perpendicularly of the film pairs if the intermediate semiconductor film were absent. More preferably, absorption of the optical beam in the narrow and the wide band gap semiconductor films is taken into account on determining their thicknesses.
