Granted: 2006-08-22
Abstract: Un cordon de soudure de cuivre est utilisé dans une opération de soudage à l'arc pour former un bourrelet qui relie une feuille de cuivre de démarrage et une barre de suspension en acier inoxydable. Le niveau de l'intensité du courant de l'équipement de soudage à l'arc est réglé pour produire de la chaleur au niveau du site de soudage qui est supérieure au point de fusion du cuivre et au-dessous du point de fusion de l'acier inoxydable. Il en résulte un joint de soudure entre le bourrelet de cuivre et la barre de suspension et un joint de brasure entre le bourrelet de cuivre de la feuille de démarrage. Du fait que le brasage produit peu ou pas de fusion, la zone de contact entre les deux métaux différents est limitée à l'interface entre eux, ce qui réduit considérablement les effets néfastes de la corrosion galvanique. Une autre amélioration réside dans l'application d'un revêtement métallique résistant à la corrosion sur l'articulation entre la barre de suspension et la feuille de démarrage à l'aide d'une technique de pulvérisation de flamme de combustible/oxygène à haute vitesse.

Abstract: A pressure sensor, a pressure control apparatus, and a flow rate control apparatus are provided in which the temperature drift of the pressure sensor is automatically corrected and pressure can be accurately detected in spite of changes in temperature. A pressure-type flow rate control apparatus, in which an apparatus for correcting temperature drift according to the present invention is installed, has an upstream side pressure sensor 10 provided between an orifice 4 and a control valve 22 for detecting an upstream side pressure P1, and controls the flow rate of a fluid passing through the orifice 4 by means of a regulating control valve 22, while calculating the flow rate of the fluid passing through the orifice 4 from the upstream side pressure P1, wherein the apparatus for correcting temperature drift comprises a temperature sensor 14 for measuring the temperature of the fluid, a memory means 64 for storing a relation between the fluid temperature T and an output drift of the upstream side pressure sensor 10, and a temperature drift correcting means which calculates the amount of the output drift of the upstream side pressure sensor 10 from data in the memory means 64 when the temperature T of the fluid changes, and offsets the output drift of the upstream side pressure sensor 10 with the calculated amount of the output drift, thereby correcting the temperature drift.  By means of this arrangement, the temperature drift of the pressure sensor is automatically corrected, which makes it possible to control accurately the flow rate.

Abstract: Use, in a cosmetic or pharmaceutical composition (A), of at least one lyophilizate (B) of dedifferentiated plant cells, where (B) causes depigmentation and/or lightening, protection and regeneration of the epidermis. An independent claim is also included for topical cosmetic or pharmaceutical compositions that contain (B). ACTIVITY : Dermatological. Human keratinocytes and melanocytes were seeded on to polycarbonate filters and grown for 10 days at an air/medium interface to produce a type VI (negroid) epidermis. Samples of this were incubated for an unspecified time with a cream (PXTS; designed for very dry skin) that contained 0.5 % of a lyophilizate of dedifferentiated cells of Crithmum maritimum. Intracellular melanin synthesis was then analyzed spectrometrically at 475 nm; absorbance was 0.160 in a negative control but 0.101 (37 % reduction) in the test sample. A further test showed a 32 % reduction in tyrosinase activity. MECHANISM OF ACTION : Blocking activity of tyrosinase (depigmentation and lightening); scavenging free radicals (protective effect) and/or stimulating proliferation of cells in the basal layer and inhibiting epidermal differentiation (regenerative effect).
