Abstract: Des compositions lubrifiantes nouvelles comprenant des polyalpha-oléfines ont un indice de viscosité élevé et un point d'écoulement réduit. Ces compositions se caractérisent par le fait d'avoir une structure moléculaire uniforme avec un faible taux de ramifications. Une composition lubrifiante liquide comprend des hydrocarbures C30-C1300 et un taux de ramifications inférieur à 0,19, un poids moléculaire moyen pondéré compris entre 300 et 45.000, un poids moléculaire moyen numérique compris entre 300 et 18.000, une distribution de poids moléculaires comprise entre 1 et 5 et un point d'écoulement inférieur à -15°C. L'invention concerne un 1-décène trimère comprenant du 9-méthyle, du 11-octylhénéicosane et du 11-octyldocosane. On produit ces compositions lubrifiantes en mettant l'alpha oléfine en contact avec un catalyseur solide réduit de support du groupe VIB (par exemple du chrome) dans des conditions d'oligomérisation à une température comprise entre 40 et 250 °C environ afin de produire un hydrocarbure lubrifiant liquide. Le produit hydrocarbure hydrogéné dans la classe des lubrifiants a un indice de viscosité compris entre 130 et 280 environ et une viscosité qui peut s'élever jusqu'à 750 mm2/s(cs). Ce procédé est particulièrement utile lorsque l'alpha oléfine de base comprend essentiellement un hydrocarbure oléfinique ayant entre 8 et 14 atomes de carbone ou des mélanges de ceux-ci, lorsque les conditions de mise en oeuvre du procédé comprennent une température de réaction comprise entre 100 et 180 °C environ, et lorsque le catalyseur de support comprend de la silice poreuse inerte.

Abstract: An imaging screen (12) for an (auto)- radiographic process, i.e. for detecting and storing information corresponding to the pattern of emission from an electrophoresis gel containing radioactively labelled, dye-tagged or chemiluminescent labelled DNA, RNA, or protein fragments. The imaging screen (12) is coated with an electron trapping material (70) which releasably stores energy from the impingement of the emission from the electrophoresis gel in the form of energy corresponding to the pattern and flux of the emission. When subjected to optical energy of a first wavelength, the electron trapping material (70) releases the stored energy in the form of optical energy of a second wavelength corresponding the flux and pattern of the emission from the electrophoresis gel. The released optical energy of a second wavelength is then detected and converted to electrical signals representative of the flux and pattern of emission from the electrophoresis gel.

Abstract: A projection system comprises a plurality of reflective LCDs (41, 42, 43) which are irradiated with colored sub-beams (21, 22, 23). The sub-beams are not perpendicularly indicent on the LCDs so that the reflected beams (24, 25, 26) do not coincide with the incident beams. The sub-beams originate from a white light beam (20) which is split up into colored sub-beams by means of color-selective mirrors (31, 33). The same mirrors are used to combine the reflected beams (24, 25, 26) to a projection beam (27). An angle-dependent beam separater (80) is arranged so as to realise a spatial separation between the incident beams and the reflected beam. The angle-dependent beam separater (80) is arranged in such a way that the angle at which the beam (20) is incident on the color-selective mirrors (31, 33) is equal to the angle at which the reflected sub-beams (24, 25, 26) are incident on these mirrors.

Abstract: The design of a current-to-voltage converter with a uniform transfer function in its feedback loop (12) is proposed. It employs a very large, double-shielded measuring resistance (13) and a two-stage setup to perform a fully linear I/V conversion with a conversion factor of 10 10  V/A and a bandwidth of 1 MHz. With the low noise level attained, and with the bandwidth and conversion factor mentioned, it will be possible to monitor events involving as few as 300 electrons. 
     The current-to-voltage converter comprises a differential input amplifier (8), a current source (11) for supplying said differential amplifier (8), at least one operational amplifier (10,14), and a high-valued measuring resistance (13) the voltage drop across which is being taken as a measure of the current to be detected. The measuring resistance (13) is arranged in a feedback loop (12) associated with said differential amplifier (8). The measuring resistance (13) is double-shielded from the remainder of the current/voltage converter circuitry through its arrangement inside a cylindrical capacitor C which acts as a first shield, and which is in turn connected to a casing (15, 25) surrounding the differential amplifier (8) and the feedback loop (12) and which constitutes a second shield.
