IPC: C23C22/30
Filed: 1990-04-06
Abstract: Zinciferous surfaces, particularly those of galvanized steel, may be effectively protected against corrosion, either as treated or after painting, while remaining easy to weld, by contact with an aqueous solution containing chromium in both +6 and +3 valence states, phosphate, a tertiary alcohol or similar oxidation stable, water soluble organic compound as a wetting agent, and a silane coupling agent, followed by drying with a film from the solution still in place on the surface. A thin coating containing 10 - 200 mg/m² of chromium is formed on the surface to provide a protective layer that is also an excellent base for paint.

Abstract: A glass sheet (6) is heated nearly to its softening point while being passed through a heating furnace (2). The heated glass sheet (6) is then clamped at its peripheral edge between first (11) and second molds (9). Thereafter, a third mold (8) is pressed against a central region of the glass sheet (6) with the peripheral edge thereof clamped, thereby to project the central region from one side to the other side thereof. The glass sheet (6) is thus pressed to a desired highly curved shape with no wrinkles or cracks developed therein. The glass sheet (6) is clamped and pressed by a pressing apparatus which includes a fixed concave ring mold (11) as the first mold, and a movable convex mold (7) comprising a peripheral mold assembly (9) as the second mold and a central mold member (8) as the third mold. The glass sheet thus curved is typically used as a front or rear window glass sheet for automobiles.

Abstract: A time multiplexed hydraulic control system is disclosed in which a multiple section dog valve (35) is multiplexed among a plurality of channels. An electrical actuator (30) on the dog valve controls pilot means (31). The pilot means (31) is associated with a plurality of followers (40,41,42), one for each channel, and each follower (40,41,42) controls the flow rate through an associated output port (36,37,38). Multiplexing means in the dog valve (35) sequentially supplies fluid to the pilot means (31) for sequentially positioning then locking the respective followers (40,41,42). Thus, each channel has continuous hydraulic flow based on the position of its dedicated follower (40,41,42), with the followers (40,41,42) being repositioned on a multiplexed basis in associated time slots.

Abstract: The circuit breaker includes a hold down 300 which slidably carries a handle barrier 302 with respect to the cover 26 and closes a centrally located aperture 304 in the cover for all handle positions. The handle barrier prevents arc products resulting from a separation of the main contacts 32 from escaping through the centrally located aperture in the cover. Stops 315 are provided in one or both directions to prevent misalignment of the handle barrier with respect to the operating handle 95. A cover interlock 330 is also provided to prevent the cover from being removed when the circuit breaker is in an "on" position. The cover interlock can either be molded separately or integrally molded with the handle barrier hold down.

Abstract: In the persuit of the forming of light composite materials which may be substituted for metal without loss of strength, composites have been manufactured from silicon carbide fibres in a titanium matrix. Titanium diffuses into the given boundaries of the silicon carbide and degrades it. Yttria (16) has been sandwiched between the titanium (18) and silicon carbide, to provide a reaction skin of yttria which reduces the extent of diffusion. The present invention oxidises the silicon carbide prior to applying the yttrium and thus further improves the resistance to diffusion.

Abstract: The procedure for erasing an EEPROM memory cell according to the invention consists, at the start of each erasure operation, in switching on a counter in a RAM memory, in carrying out an erasure cycle as recommended by the constructor, and then a cycle of reading and comparing the voltage read with an expected voltage corresponding to the "erased" state of the memory cell, and then, if the voltage read is not the expected voltage, in incrementing the counter and operating a new erasure, reading and comparison cycle. When the voltage read is the expected voltage, a return code characteristic of the contents of the counter and hence of the number of erasure cycles which were required for the erasure operation is emitted, destined for the user. The procedure applies, in particular, to unpowered EEPROM memory devices of the chip card type. …<IMAGE>…

Abstract: The piston rod guide bearing (8) arranged between a cross head and a cylinder is oil-lubricated and has a housing (13), which on the side facing the cross head contains a bearing section (17, 19) enclosing the piston rod (7) and on the side facing the cylinder an oil scraper device (23) at a distance from the bearing section. The housing (13) is designed in such a way that the lubricating oil scraped off during the stroke of the oil scraper device (23) directed at the cylinder forms an oil bath in the housing (13). In addition the housing (13) in the area of the oil bath (24) has no discharge to the outside and the bearing section (17, 29) is gas-tight during operation. As a result of this design, the lubricating oil scraped off and collected in the oil bath is forced back into the crank casing by the route by which it entered the bearing housing. <IMAGE>

Abstract: L'invention se rapporte à un procédé et à un appareil de génération automatique de vibrations pour excavateur hydraulique, qui sont utilisés pour un excavateur hydraulique comportant une machine de travail composée de flèches, bras, et d'un godet et qui servent à imprimer un mouvement vibratroire approprié à la machine de travail, afin de réduire les résistances à l'excavation en dépit des changements de nature du sol et de la diversification des tâches et afin de permettre des travaux d'excavation efficaces. Dans la présente invention, notamment un mode opérationnel (Bo, A, Bu, Sk) et un mode vibratoire (L, M, S) sont sélectionnés au préalable en fonction de la nature du sol et d'un modèle d'opérations, et un mouvement vibratoire approprié est automatiquement généré en mode vibratoire automatique. La charge opérationnelle d'un levier de la machine de travail est additionnée au mouvement vibratoire décrit ci-dessus. Pour cette raison, même lors d'un travail répétitif simple et délicat, tel que des travaux de roulage, de criblage ou d'excavation avec application d'un mouvement vibratoire au godet, le travail peut s'exécuter facilement et uniformément sans trop charger ni fatiguer l'opérateur, et l'efficacité du travail peut être notablement améliorée.

Les compositions présentent des viscosités à 100°C comprises entre 725 mm2/s et 15 000 mm2/s. L'emploi des compositions précitées en mélange avec de l'huile minérale et des lubrifiants synthétiques permet d'obtenir de nouveaux mélanges lubrifiants qui possèdent un indice de viscosité élevé. Ces mélanges possèdent également une stabilité accrue au cisaillement à haute température et présentent tous un écoulement newtonien remarquable.
