IPC: F01C1/20
Filed: 1998-02-04
Abstract: A rotary device (30) has a first rotor (3) having a recess (4) and a second rotor (5) counter-rotatable to said first rotor (3) and having a radial lobe (6). A housing (20) in which the rotors (3, 5) are enclosed has a first arcuate recess (21), an edge (42) of the recess (4) of the first rotor (3) forming a sliding seal with the first arcuate recess (21) during a portion of the rotation of the first rotor (3). The housing (20) has a second arcuate recess (22), the lobe (6) of the second rotor (5) forming a sliding seal with the second arcuate recess (22) during a portion of the rotation of the first rotor (3). Thus, for a portion of the rotation of the rotors (3, 5), there is defined betwen the first and second rotors (3, 5) and the arcuate recesses (21, 22) of the housing (20) a transient chamber (23) of volume which progressively decreases on rotation of the rotors (3, 5). The maximum volume of the transient chamber (23) can be varied.

Abstract: The inventive weaving loom contains a weaving reed (8) and a weft thread guide device (32) which is able to pivot between an insertion position and a stop position. A fixed weft thread insertion device (32) is provided for inserting a weft thread (38) into the guide channel (36) and cutting blades (15) are provided for cutting the weft thread after nipping.      A device for forming the selvedge is also provided in order to nip an inserted weft thread (38) by means of friction and to ensure that the nipped effect is maintained whilst said thread is conveyed from the insertion position to the stop position. The fixed position of the insertion device and the functional arrangement of the nipping element and scissors in relation to the weaving reed mean that the process is easier to control, to the extent that up to sixteen different weft threads can be inserted.

Title: Method and apparatus for integrating multiple repeaters into a single collision domain
Inventor: SOKOL MICHAEL A
IPC: H04L12/44
Filed: 1998-02-18
Abstract: A system for integrating multiple repeaters (102, 104) into a single collision domain employs both analog and digital circuitry to convey system-wide collision information to repeaters thereby allowing seamless integration of multiple repeaters (102, 104) into multiple hubs (100) without requiring additional drivers or external glue logic. One signal line (CFSL 112) within each hub is used to aggregate collision information within the hub. Further, only one signal line (CFSS 108) is used to aggregate collision information between hubs (100). This latter signal line in conjunction with two intra-hub signal lines (COLZ, 116 and SNGLZ, 114) distributes system-wide collision information to all of the repeaters (102, 104) in all of the hubs (100).

Abstract: L'invention concerne un procédé et un dispositif permettant de couler des structures et utilisant la technique du coffrage. Ce dispositif et ce procédé sont applicables, entre autres choses, au coulage sur place de panneaux de construction en béton destinés à être érigés ultérieurement. Retirés par rapport à l'emplacement du coffrage, se trouvent des contreforts retirés (11) fixés à la surface du chantier. Lesdits contreforts (11) soutiennent des panneaux de tenue coulissants (25-29) qui peuvent être fixés à demeure par rapport audits contreforts (11) et qui peuvent être dégagés et déplacés en direction et à partir de l'emplacement du coffrage. Lesdits panneaux de tenue coulissants (25-29) soutiennent le coffrage au niveau de l'emplacement du coffrage. Une pluralité de panneaux de tenue coulissants (25-29) peuvent être soutenus par les contreforts retirés (11) disposés l'un au dessus de l'autre. Ainsi, des joues de coffrage peuvent être soutenues dans des structures aux profils verticaux complexes; des murs convexes ou concaves, des marches et des colonnes de panneaux de construction peuvent, par exemple, être coulés. L'invention concerne également des joues de coffrage réutilisables qui sont soutenues par les panneaux de tenue coulissants (25-29) et qui peuvent être utilisées en tant que coffrage pour des panneaux de construction. Les joues de coffrage peuvent être assemblées bout à bout, et également extrémité arrière contre extrémité avant, en vue de former ainsi des moules rectangulaires continus.

Title: Method for processing atm cells in bidirectional data streams
Inventor: AMANDI DIRK
IPC: H04L49/111
Filed: 1998-07-02
Abstract: The invention relates to a method for processing ATM cells in upstream and downstream bidirectional data flows in an ATM component in which the processing speed is greater than the mean cell rate and empty cycles without ATM cells are present in the cell flow. To allow for two-way alternate processing of upward and downward cells, the processing logic (VAL) of the component (BST) issues requests (EC up req, EC down req) for empty cycles upstream and downstream to an empty- cycle control unit (LZS) so as to obtain processing time. The cells of the downstream data flow can be stored and released separately in a buffer (BUF) so that in this way empty cycles can be generated downstream. Should an empty cycle occur, an upstream request for empty cycles (EC up req) is processed as a priority in relation to a simultaneous downstream request. In case of a downstream empty cycle request (EC down req) an empty cycle is released with a delay of one cycle period if there is a simultaneous upstream request. If this is not the case, it is released immediately.

Title: Quotation mechanism for service environments
Inventor: WEISS MICHAEL
IPC: G06Q30/00
Filed: 2000-05-05
Abstract: The present invention provides a quotation mechanism for service environments where the service level is negotiated. A client makes a request for a type, quality or volume of service. The service provider provides a response in the form of a quote. A quote binds the service provider to providing a service at a specified price. The quote also contains parameters of type, quality, or volume of service that the service provider can provide at that price. The client, after evaluating the quote, can either accept or reject a quote. The client can also obtain quotes from multiple service providers and enter a service contract with the service provider of its choice. This choice will not be based solely on price, but also on the levels of service quoted, since the service provider might not be able to supply the service at the requested level.
