Patent EP-0618476-A1 (EP)
Inventor: BLANCHARD RANDALL D
IPC: G03B21/62
Filed: 1994-03-30
Abstract: A projection system having a rear projection screen (28) employs a collimating lens (26) in the form of a Fresnel lens adjacent the rear surface of the screen (28) to improve the image luminance at various viewing angles and provide uniform brightness over the area of the screen. A fiber optic face plate (30) or two crossed films of microlouver light control material is interposed between the collimating Fresnel lens (26) and the rear of the projection screen (28) to provide a high degree of blocking of high intensity light, such as sunlight, that may impinge upon the front of the screen. The optical fibers (42) of the fiber optic face plate have a low numerical aperture and an opaque cladding. The arrangement allows an image to be provided on the screen with high contrast even in the presence of sunlight striking the screen.

Abstract: Silicon nitride powder is prepared by nitriding metallic silicon powder in a nitriding gas atmosphere at a temperature of 1,000°C-1,500°C. Midway the nitriding step, the nitrided product is heat treated in an inert non-oxidizing gas atmosphere or vacuum at a temperature higher than the nitriding temperature, but lower than 1,600°C. The product is nitrided again, obtaining high α-content silicon nitride powder.

Abstract: In a system (1) for producing compressed air, of the type comprising an electric motor (26) driving a rotary compressor (4), air is supplied directly by the compressor (4) to one or more services or tools (28) without using any intermediate storage device such as a receiver; the demand for greater or lesser quantities of air is met by varying the speed of rotation of the electric motor (26), hence of the compressor (4), in response to a difference between the supply pressure (Pr) registering at the outlet of the compressor (4) and a preset operating pressure (Pu). The difference in the two pressures is monitored continuously, and as a result of the variable speed characteristic remains constantly at a negligible level.

Abstract: A heating furnace system is provided for receiving finite lengths of workpieces from one or more continuous casters and form a supply of heated workpieces at a temperature suitable for rolling in a hot rolling mill. The system includes, in one aspect, a holding furnace receiving a workpiece during continuous casting until it is severed by a cutoff device to prevent unwanted cooling. The workpiece is fed from a holding furnace to a heating furnace wherein it is deposited onto one of a series of vertically spaced supports in a heated section where it remains static throughout the heating process. After heating the workpiece is removed from the stationary supports and returned to rollers of a hearth for discharge from the furnace to a rolling mill. In a second embodiment the holding furnace arrangement provides for separate holding furnaces to receive continuous castings from separate continuous casters and prevent unwanted cooling of the cast workpiece until cut to a finite length. The holding furnaces have doors and longitudinal sides walls to allow transfer of the workpieces seriatim through doors in a central heating furnace. The central heating furnace is aligned with the hearth as in the first embodiment and supplies workpieces serially through the heating furnace.

Abstract: An excavating tooth (10) for use on a wide variety of excavating equipment is comprised of a point (12), an adapter (14) and a sandwich lock pin (16). The pin includes a rigid casing (54) and a plurality of independently depressible protrusions (58, 59). One of the protrusions (58) resiliently engages a face (22) defined on the nose of the adapter to tighten the connection of the point on the nose. One other of the protrusions (59) extends into an opening (50) defined by the point to secure the lock pin to the point. With respect to an external locking tooth, the opening (50) defined in the point includes a pair of bosses (155a, 155b) which define a reduced portion of the opening. The reduced portion matingly receives and holds the ends of the rigid casing of the pin. The independent locking of the pin and the mating receipt of the casing in the point opening reduces the likelihood of pin loss due to overloading of the elastomeric material, wearing of the components or jacking forces.

Abstract: Cette invention se rapporte à un système de convertisseur analogique/numérique (CAN), dans lequel les données CAN brutes sont reçues et manipulées numériquement, afin d'accroître la précision du mot de sortie numérique résultant. Dans un mode de réalisation de cette invention, la manipulation numérique est effectuée sur des données qui ont été préalablement ajustées pour corriger les erreurs causées par l'utilisation d'un gain entre étages inférieur à un niveau idéal. Dans un mode de réalisation de cette invention, la correction numérique s'effectue sur la base uniquement des erreurs de plusieurs étages de bits de poids fort, plutôt que de tous les étages, étant donné que l'effet de l'erreur sur le mot de sortie numérique est d'une importance décroissante pour les étages de bits de poids moins fort. Selon un mode de réalisation de cette invention, on détermine l'erreur de décalage et l'erreur de pleine échelle, en appliquant le signal ±Vref comme signal d'entrée au convertisseur analogique/numérique. Ces valeurs permettent de compenser aussi bien dans le matériel que dans le logiciel les données numériques brutes provenant du CAN, afin d'obtenir une représentation numérique plus précise de la tension d'entrée analogique à mesurer. Selon un autre mode de réalisation de cette invention, on élimine les erreurs de second ordre en déterminant l'amplitude par exemple des coefficients de tension de valeurs de condensateur de l'étage de bits de points fort du CAN, après étalonnage des étages de bits de points moins fort, et en utilisant ces coefficients de tension pour obtenir un ajustement supplémentaire du mot de sortie numérique, fournissant ainsi une représentation numérique encore plus précise du signal d'entrée analogique à mesurer.
