IPC: G01K7/00
Filed: 1990-08-08
Abstract: The invention relates to a device for measuring the temperature of the winding of electrical machinery. The temperature measurement is performed by evaluating a current/voltage measurement of alternating signals which are not at system frequency. The measured voltage is added geometrically to the system voltage and generates a current which is proportional to the temperature-dependent winding conductance. The frequency of the measuring signals is preferably below 10 Hz.

Abstract: L'appareil à coussin d'air, tel qu'une tondeuse à gazon, est constitué d'une enceinte sans fin (12) ayant une ouverture dans le fond qui est définie par une plaque relativement plate (42) faisant saillie vers l'intérieur pratiquement sur tout le pourtour du fond de l'enceinte (12). Au moins un impulseur pneumatique (14) assure la pressurisation à l'intérieur de l'enceinte (12) de manière suffisante pour faire flotter l'enceinte au-dessus d'une surface de support. La plaque (42) dirige l'air latéralement dans l'enceinte (12) pour empêcher l'air de s'échapper de l'enceinte (12) et maintenir une pression relativement constante dans l'enceinte (12). L'action rotative de la lame (16) de coupe de la tondeuse à gazon centrifuge les brins d'herbe coupés se trouvant dans l'enceinte. La plaque (42) joue le rôle de support des brins d'herbe coupés centrifugés et coopère avec une paroi interne (38) de l'enceinte (12) pour acheminer les brins d'herbe coupés dans un conduit de décharge (30) et les récupérer dans un sac ou autre récipient.

IPC: C08K5/13

Abstract: Excellent color stabilization as well as fiber integrity is obtained in bright sunlight and at relatively high temperature, in polyolefin (PO) articles pigmented with phthalocyanine pigments, by combining the pigment with two 'large molecule' primary stabilizers, the first a hindered amine light stabilizer (HALS) and the second a 3,5-disubstituted-tert-butyl-4-hydroxybenzoate (3,5-DHBZ). The first contains at least one triazine ring, and each substitutable position on each triazine ring is substituted with an oxo-piperazinyl group; the second is a hindered phenol with an ester group in the  para-  position. Stabilization of the PO's color is obtained for as long as the PO articles themselves are stabilized by the combination of primary stabilizers. With the combination, phthalocyanine pigmented articles are not only thermooxidatively and light-stabilized, but there is exceptionally low color fade. Because fibers are extruded twice for better distribution of pigment, a small amount, no more than 0.1 phr of secondary melt-stabilizers, may be used. Blue- and green-pigmented PO articles in particular, so stabilized, exhibit less than a ±2 change in color (color fading) due to degradation of the pigment, over exposure resulting in absorption of 1240 Kjoules. Such exposure, deemed equivalent to exposure to sunlight for about 2 years in Florida at a 45° South exposure, of PP fibers pigmented with the combination of primary stabilizers suffer essentially no loss of color due to degradation of the pigment.
