Abstract: La présente invention a pour objet un dispositif de détection de vitesse angulaire comportant un isolateur de vibrations, une plaque de fixation supportant un diapason utilisé comme capteur de vitesse angulaire de type vibrant, un collier, une plaquette de circuits imprimés servant à commander le fonctionnement du diapason ainsi que la production de signaux de sortie, et à travers laquelle une pluralité de broches de connexion sont insérées dans un ordre déterminé depuis la surface inférieure d'un boîtier de forme concave. Les circuits et le diapason sont interconnectés par l'intermédiaire d'une plaquette de circuits imprimés flexible. Ces composants sont logés à l'intérieur du boîtier de forme concave. Un couvercle ferme la partie supérieure du boîtier pour en assurer la complète étanchéité. Le dispositif de détection de vitesse angulaire en question est à l'abri de toute variation de ses propriétés opérationnelles qui pourraient découler de vibrations parasites, et de la détérioration des propriétés de son isolateur de vibrations. En outre, les effets adverses de l'humidité et des gaz corrosifs présents dans l'atmosphère ne peuvent altérer les propriétés opérationnelles du dispositif en question en raison de l'étanchéité de son boîtier.

Abstract: Tertiary amines having carbonate and urethane groups and optionally hydroxyl groups are produced by reacting a) a polyhydric alcohol and b) a primary-tertiary diamine with c) a carbonic acid derivative selected from the group consisting of optionally cyclic carbonates, urea, phosgene and bis-chlorocarbonates of alcohols of the same type as those used as component a). This reaction may be carried out in one or two steps. The tertiary amines produced by this process are useful as catalysts, which may optionally be incorporated into an isocyanate-reactive material, in the isocyanate addition reaction for the production of polyurethane plastics. These tertiary amines are particularly useful for the production of foam backed plastic films.

Title: Tool actuator with adjustable attachment mount
Inventor: WEYER DEAN R
IPC: E02F3/38
Filed: 1995-12-13
Granted: 1999-08-03
Abstract: A fluid-powered, laterally tiltable tool actuator. A tool has a pair of clevises, and an actuator has a generally cylindrical body with an output shaft rotatably disposed therein with an axis in general parallel alignment with a forward rotation plane through which the tool is rotatable on a backhoe arm by the operation of a rotation link. A bracket is attached to the body and has a pair of clevises for pivotal attachment to the vehicle arm and rotation link. The output shaft has a pair of shaft attachment members at each end for attaching the shaft to the corresponding toolclevises. The first pair of shaft attachment members is rigidly fixed to the shaft and attached to a first tool clevis. The second pair of shaft attachment members is pivotally attached to the shaft and pivots in a plane generally parallel to the longitudinal axis of the shaft. The pivoting attachment members can be adjustably positioned to accommodate various distances which separate the first and second tool clevises of different tools to allow the pivoting attachment members to be readily attached to a second tool clevis. A linear-to-rotary transmission device disposed within the body produces rotational movement of the shaft relative to the body to produce lateral tilting of the tool in a lateral plane generally transverse to the forward rotational plane.

Granted: 2000-07-25
Abstract: The present invention discloses novel nitrogen-hydrogen based atmospheres for sintering steel components in continuous furnaces with consistent quality and properties while prolonging the life of the wire mesh belts, reducing maintenance costs, and improving furnace productivity. Specifically, it discloses the use of a controlled amount of an oxidizing agent such as moisture, carbon dioxide, nitrous oxide, or mixtures thereof along with nitrogen-hydrogen atmospheres to (1) sinter steel components with consistent quality and properties, (2) prolong life of wire mesh belts, (3) reduce downtime and maintenance costs, and (4) reduce the formation of soot in the furnace. The use of a controlled amount of an oxidizing agent has been unexpectedly found to form a protective and adherent oxide layer on the belt material, eliminate complete reduction of the belt material in the heating zone of the furnace, and prevent sticking of sintered components on the belt material, all of which are responsible for significantly increasing belt life by reducing (1) erosion of the belt material caused by cyclic oxidation in the preheating zone of the furnace or in the ambient atmosphere outside the furnace and reduction in the high heating zone of the furnace, (2) embrittlement of belt material caused by the formation of metal carbides and nitrides, and (3) degradation of belt material by splashing of foreign material from parts being processed onto the belt. The amount of an oxidizing agent added to the nitrogen-hydrogen atmospheres to pre-condition belt material prior to its use for sintering and to sinter steel components is controlled in such a way that atmospheres become oxidizing to the belt material but reducing to steel components being sintered, specifically in the high heating and cooling zones of continuous furnaces.

Abstract: L'invention concerne un réseau de multiplexage de données qui effectue le multiplexage d'une pluralité de canaux de données asynchrones avec un flux de données asynchrone représentant des signaux vocaux et/ou des signaux de télécopie comprimés en un unique flux de paquets de données synchrone. Cette unique flux de paquets de données synchrone est ensuite transmis par un multiplexeur statistique haute vitesse, par l'intermédiaire d'une liaison composite, à un second site, au moyen d'un protocole de commande de liaison pour données synchrone de haut niveau avec superposition d'un algorithme de multiplexage statistique à priorité évolué. Les canaux de données asynchrones et les signaux vocaux et/ou de télécopie comprimés subissent un démultiplexage et sont reconstruits pour être transmis, respectivement, à d'autres terminaux informatiques asynchrones et à un port analogique standard de téléphone ou de télécopie, sur le second site. Des interfaces de jonction d'autocommutateurs privés sont également prévues, ces interfaces permettant aux autocommutateurs privés de partager la liaison composite entre les sites. La communication par signal vocal ou signal de télécopie entre le premier site et le second site est transparente pour les utilisateurs. Le multiplexeur affecte de façon efficace la largeur de bande de la liaison composite en détectant les périodes de silence dans les signaux vocaux et en supprimant l'émission de l'information vocale pour conserver la largeur de bande. L'invention concerne également un multiplexeur statistique à priorité évolué qui affecte, de façon dynamique, la largeur de bande de la liaison composite à des données à durée de vie critique et également à des données à durée de vie non critique pour maximiser l'efficacité et la qualité globales de la transmission des données tout en réduisant simultanément le surdébit de traitement du multiplexeur.

Granted: 1999-10-12
Abstract: A sideframe pedestal jaw accommodates a bearing adapter which locks the adapter to the sideframe, thereby preventing it from all forms of movement within the pedestal jaw opening. Locking the bearing adapter forces the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck warpage, which induces wheel misalignment that leads to undesirable truck hunting and high speed instability.
