Abstract: The use of a thermal spray method relates to the production of a layer (20) for a heat insulating coat of a material (10) in powder form. This material consists at least to 80 mol% of zirconium silicate ZrSiO4, in particular of the mineral zircon, and the majority of its powder particles (1) have diameters in the region between 10 and 100 µm. During the spraying on the particles are at least partially melted through in a gas flow (42) under reducing conditions and at a temperature greater than 2000°C. Method parameters, among others the dwell time of the particles in a heat imparting medium, in particular a plasma (41) or a flame, the temperature of the heat imparting medium and the momentum transferred to the particles, are chosen in such a manner that the layer (20) which is formed of the particles has a structure with lamellar elements (21). Suitable gases or gas mixtures, preferably hydrogen, are used as reducing means for the liberation of gases containing silicon, in particular silicon monoxide SiO; and/or a thermal liberation of gases containing silicon takes place as a result of a high temperature of the heat imparting medium.

Abstract: There are provided an ocular optical system simulating method and a simulating apparatus which enable simulation of how things can be seen, together with fluctuation, deformation, blur, etc. , occurring when a lens system such as a progressive addition lens is worn. A rotation-based retinal image, defined as an image obtained by turning an eye-ball with respect to all object points within a field of vision and by connecting images caught at the fovea, is made. The image is made by first creating an original image having a specific angular field of vision and entering the eye having a specific rotation center point. Then, a deformed original image having deformation occurring when the original image is seen through the lens system is created by using ray tracing. A PSF on the retina of an eye-model from light from the object points of the original image in an optical system composed of the lens system and a spectacle model is determined. Next, the deformed original image and the PSF of each pixel of the original image are convoluted. The obtained rotation-based retinal image is edited further to result in a motion picture image of the rotation-based retinal image. The PSF is found by selecting sampling points on an object and the PSF other than those at the sampling points is found by using approximation methods including spline interpolation.

Abstract: Cette personnalisation de cartes à puce comprend un processus de préparation préalable à la session de personnalisation, laquelle s'effectue au niveau du bureau de personnalisation. Ce processus de personnalisation dérive les clés dérivées pour la carte et destinées à une ou plusieurs applications, et il produit également des paires et certificats de clés publiques relatives à l'émetteur et à la carte. Des clés maîtresses sont utilisées conjointement avec le processus de préparation de la personnalisation, plutôt que lors du reste du processus de personnalisation, au niveau du bureau de personnalisation. Etant donné que ce processus de préparation de personnalisation ne nécessite par un appareillage hautement spécialisé et cher, l'émetteur peut facilement dériver les clés de la carte, à l'endroit où il est situé. Une fois achevé le processus de préparation de personnalisation, les clés dérivées sont conservées dans un fichier de sortie combiné à d'autres données de personnalisation de la carte. Le fichier de sortie contient les enregistrements des données secrètes et non secrètes de la carte, chaque enregistrement correspondant à des informations de personnalisation d'une seule carte à personnaliser. Le fichier de sortie est envoyé au bureau de personnalisation, lequel traite le dossier au moyen de modules de traitement classiques, afin de personnaliser chaque carte à puce. Les processus de préparation et de personnalisation peuvent s'effectuer au même endroit ou dans des endroits différents.

Abstract: An apparatus for automatically preventing wear in an internal combustion engine includes an electric pump (19), a disconnect coupling (26), a high arrestance filter (60), a programmable logic control element (36), and an external controller (44). The programmable logic control element is connected to a normally provided battery (42) and automatically switches control power from the battery to the electric pump according to a programmed control operating cycle program, and is operatively independent of ignition switch activation or operator action. The inlet of the electric pump is connected to the normally provided engine oil sump (12) for removing lubricating fluid. The lubricating fluid is pumped through the high arrestance filter, yielding a substantially contaminant free lubricating fluid which after flowing through a radiator is discharged into the normally provided engine lubricating gallery (54). The external controller, such as a wireless remote control, is provided to activate the pump remotely upon demand. >

Title: Belt conveyor with increased capacity
Inventor: EBERLE MARC
IPC: B65G15/08
Filed: 2000-09-20
Granted: 2003-06-17
Abstract: A belt conveyor for conveying granular material comprises a tube and a hopper. Guide members guide the belt from a flat orientation as the belt leaves the lower roller into a cupped orientation as the belt enters the hopper. The cupped orientation ins maintained by sliding contact at an interface between the lower surface of the belt and the hopper walls as the belt passes through the hopper. Left and right baffle members are attached along the hopper side walls and thereby prevent the granular material from sliding down the hopper walls into contact with the interface between the lower surface of the belt and the hopper walls. The belt has a width that is substantially fully exposed to granular material entering the hopper. A method of increasing the capacity of a belt conveyor comprises reducing the width of the flashing covering belt side portions.
