A differential gear which can always obtain a stable differential limiting force even in low-speed rotation. A plurality of rollers are provided between a raceway surface integrally rotating with an input-side rotating body and a raceway surface integrally rotating with an output-side rotating body. A tilt angle of the axes of rolling of the rollers with respect to the axis of rotation of the race...

A sinter of noble metal produced by forming in a required shape or attaching to a given object a plastic art grade clayish composition or adhesion composition comprising a noble metal powder containing at least one member selected from the group consisting of pure noble metal powders and noble metal alloy powders, 0.022 - 3.0 wt. % of a water-soluble cellulose type resin, 0.02 - 3.0 wt. % of starc...

A process of manufacturing at least a portion of a plaster-based water resistant construction element including the steps of :mixing together a dry material comprising at least a major portion of hydratable calcium sulfate, a water repellency agent, and hydrating water to form a homogenous mixture; preforming in the wet state the said portion of said construction element, from said homogeneous mix...

Apparatus for sewage purifying treatment for improving dissolved oxygen content by micronizing coarse bubbles due to the synergistic effect of introduced pressurized water flow and the air introduced from the outer circumferential part of the introduced pressurized water flow as it is spiralling and injecting such pressurized water containing micro-bubbles into waste water and also for carrying ou...

The present invention concerns a device for preloading of a spring (1) which has a first end rigidly attached to a first support means (5) and a second end rigidly attached to a second support means (7), at least one of said support means being rotatable around an axis of rotation relative to the other support means, thereby tensioning or detensioning said spring, and where the spring and both sup...

A method for manufacturing an aluminum-based composite plate (54) is disclosed. The method comprises the step of producing an aluminum-based composite billet(45). The billet production step includes reducing, by magnesium nitride (44), an oxide-based ceramic (31) as a porous molded body. The reduced oxide-based ceramic has improved wettability. An aluminum alloy (41) is then caused to infiltrate i...

Date Mar. 21, 1996In a communications network involving transmission of data packets, control messages between nodes are assigned priorities dependent on message type. The allocated of messages to TDM/TDMA time slots is dependent on the assignment priorities.

An end user local network and a packet data communication network are interconnected by an arrangement including a packet data network backbone, at least one packet data node with a serving functionality for handling packet data communication, and a gateway functionality for providing communication with external network(s). At least one virtual distributed node provides a gateway functionality and...

A pipe collar (10) for attachment to the ends of two adjacent pipes that forms a seal and connection between the pipes. The collar has two separable arcuate halves (15 and 20). A projection (16) interlocks with a bearing surface (22) to allow hinging from an open position to a closed position. In its closed position, flanges 17 and 26 are adjacent allowing clamping together with a bolt or other cl...

A system for electronically managing, finding, and/or visualizing biomolecular interactions is described. A computer-implemented system of the invention has a database having a plurality of records. Each record contains a reference biomolecular interaction defined by a chemical graph and descriptive information from an external database. The information correlates the biomolecular interactions to ...

At least some of the panels (2) in the unit (1) include a perforated support and are coated or laminated on one side with a film having good heat transfer properties. The preferably disposible unit contains a number of flow channels (10, 11) for incoming and outgoing air (3, 5), formed between panels kept apart by spacer elements (7, 9). An Independent claim is also included for an air treatment ...

L'invention concerne de nouvelles compositions cosmétiques à usage topique, en particulier pour la photoprotection de la peau et/ou des cheveux, caractérisées par le fait qu'elles comprennent, dans un support cosmétiquement acceptable notamment de type huile-dans-eau, (i) l'acide benzène 1,4-di(3-méthylidène-10-camphosulfonique), éventuellement sous forme partiellement ou totalement neutralisée, à...

In a communication network, a wireless channel is selected from multiple channels. The interference level of the selected channel is determined and a first quality value is derived and compared to a first decision threshold. If the first quality value is smaller than the first decision threshold, the selected channel is abandoned and a new channel is searched. If the first quality value is greater...

A circuit pack blank occupies an unequipped position in an electronic equipment shelf that is cooled by forced-air convection. The blank incorporates two diffuser blades that protrude into a cooling space in the shelf adjacent to the blank. When air is forced through the cooling space at a constant velocity, a backpressure is generated that is equivalent to backpressures generated at cooling space...
