Title: Method and circuit arrangement for setting up virtual connections via an atm trunk group
Inventor: WALLMEIER EUGEN
IPC: H04L12/56
Filed: 1992-07-17
Abstract: ABSTRACT OF THE DISCLOSURE A method and circuit arrangement for connecting ATM communication equipment to an ATM trunk group, where characteristic parameters reported for virtual connections to be set up are allocated to connection classes and to transmissionclasses corresponding to the connection classes. The parameters are defined for the individual lines of the ATM trunk group. Further, line particulars with respect to all of the transmission classes for which a virtual connection can still be set up, based on currently available free transmission capacity, are individually retained for the associated individual ATM trunks. When a request for setting up a virtual connection is present, an individual trunk for setting up the virtual connection is selected during the course of a search event involving the line particulars of all individual trunks. A transmission class that corresponds to the connection class to be considered in the virtual connection to be set up is determined from the line particulars of the individual trunk.

Abstract: The heat sealing wire of an impulse heat sealer is held against an operating face of a support bar by an insulating fabric which is draped over the wire and secured in a slot formed in the support bar.  The securing drape of fabric allows unrestricted expansion and contraction of the hot wire.  Also if the slot lies in a curved plane which extends perpendicular to the plane of the support bar operating face, the drape of insulating fabric and consequently the sealing wire follow the same curve so the heat sealer can make seals of a non-linear configuration.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for crimping the adjacent side edges of two panels includes a base with first and second crimping members.   One of the crimping members is fixed to the base while the other is  threaded on a  screw member secured to the base.  The screw member is rotated by a motor  to  drive  the  crimping members  together.    The apparatus is placed on adjacent panels of the type having preformed mating side edges.  The side edge of one panel is in the form of an inverted channel in which the side edge of the other panel fits.  The apparatus crimps the side edges so that a downturned leg of the channel is folded onto a portion of the other panel's side edge, thereby crimping the panels together so that a rotary seaming apparatus can be applied to provide a permanent watertight connection.  The apparatus is provided with a non-abrasive material to prevent scratching or marring of the panel surfaces.

Abstract: Abstract Of The Invention CORRUGATED NONWOVEN WEBS OF POLYMERIC MICROFIBER      A composite structure contains a lofty corrugated nonwoven web of polymeric microfiber that is maintained in a corrugated condition by securing a fabric to the corrugated web at the valleys of the corrugations. The composite structure is made without substantially effecting web loft by (i) introducing the nonwoven web to the ends of a plurality of spaced paddles, (ii) causing the spacing between the ends of the paddles to decrease to corrugate the nonwoven web, and (iii) securing the fabric to the corrugated nonwoven web at the valleys of the corrugations. A composite structure of this construction made by this method provides very good filtration performance, making it particularly suitable for use as a filter in a cup-shaped face mask. The composite structure also is very suitable for use as thermal insulation in apparel.

Title: Method for resolution of natural-language queries against full-text databases
Inventor: ADDISON EDWIN R
IPC: G06F17/30
Filed: 1993-11-03
Abstract: Abstract The method of the present invention combines concept searching, document ranking. high speed and efficiency, browsing capabilities, "intelligent" hypertext, document routing. and summarization (machine abstracting) in an easy-to-use implementation. The method of the present invention also offers Boolean and statistical query options. The method of the present invention is based upon "concept indexing" (an index of "word senses" rather than just words.) It builds its concept index from a "semantic network" of word relationships with word definitions drawn from one or more standard human-language dictionaries. During query, users may select the meaning of a word from the dictionary during query construction, or may allow the method to disambiguate words based on semantic and statistical evidence of meaning. This results in a measurable improvement in precision and recall. Results of searching are retrieved and displayed in ranked order. The ranking process is more sophisticated than prior art systems providing ranking because it takes linguistics and concepts, as well as statistics into account.

Abstract: In a satellite communication network, a reference station (RS) simultaneously announces a reference time of a reference clock (23) once in a predetermined duration of time to all terrestrial stations of the network.  In each terrestrial station (TS(n)) which comprises a local clock (13), a packet forming arrangement (11, 15), a data extracting arrangement (11, 19) for extracting a local time datum from a packet received from a different terrestrial station, and a calculation unit (21) for calculating a propagation delay time between the different terrestrial station and the terrestrial station under consideration by subtracting from the local time datum a current time indicated by the local clock when the local time datum is extracted, a time setting arrangement (25, 27) sets the current time at a sum of the local time datum and a constant preassigned to the terrestrial station in question.  The constant is preliminarily decided by calculating a distance on the earth between the terrestrial station and the reference station based on their longitudes and latitudes, calculating a physical length of a communication link by using the distance, and calculating a time necessary for electromagnetic waves to travel the physical length.  It is possible to substitute one of the terrestrial stations as a center station for the reference station.  The physical length is calculated by furthermore using either one-way propagation delays from the terrestrial station under consideration and from the reference or the center station to a satellite of the network or the longitude of the satellite.
