Abstract: An endoprosthesis for the internal support of hollow organs in living creatures comprises a flexible tubular mesh structure (2) with open ends (4) and an elastic tubular covering (6), whereby the mesh structure (2) is composed of circumferentially extending mesh rows (8, 8'), consisting of lined up spaces (12, 12') enclosed by mesh material (10). In the region of an open end (4) of the mesh structure (2) the covering (6) comprises an embedding portion (14), enclosing at least partially the mesh structure (21, and a projecting portion (16), following next to the embedding portion (14) and projecting over the open end (4).      By this means a hollow organ is protected against pointed or sharp-edged terminating parts projecting from the open end (4), specifically when the endoprosthesis is moved within the hollow organ by the peristaltic of the hollow organ or by removing of the endoprosthesis from the hollow organ.      Besides that the projecting portion (16) provides a target area for a gripping device when an implanted endoprosthesis is intended to be repositioned.

Abstract: An exchange comprises a plurality of distributed nodes for processing calls from or to a first neighbouring exchange, two or more of said nodes being arranged to be connected to the first neighbouring exchange by separate trunk routes, and a signalling point code being assigned to the node-end of each trunk route, wherein the signalling point cods assigned to the node-ends of the separate trunk routes to the first neighbouring exchange, differ from each other.   The first neighbouring exchange sees the exchange as if it were two or more conventional exchanges. The total amount of call processing for handling a call in a network which incorporates one or more exchanges of the invention can be reduced.

Abstract: The present invention provides improved methods of producing platinum compounds, which are very suitable for producing labelled substances, which can be used to detect specific molecules of interest. The platinum coordination compounds have two reactive groups of which one is replaced by a label and the other one can be replaced by a substance to be labelled. Production of labelled substances is very much improved by selection of the right starting materials and producing the right intermediates. The efficiency of labelling is very much improved, thereby enabling the production of labelling kits which are also a part of the present invention.

Title: An atm switch queuing system
Inventor: WILLS JEFFREY MERLIN
IPC: H04L12/56
Filed: 1997-12-12
Granted: 2002-09-17
Abstract: An ATM switch with a switch queuing system which minimizes cell loss for bursty traffic, while avoiding delay for time-critical. The switch has a plurality of input ports and a plurality of output ports, a switch fabric transmitting cells from the input ports to the output ports, and a backpressure signal circuit connected between each output buffer of each output port and each input buffer of each input port. Each input port has an input buffer holding ATM cells when the cells arrive faster from the port's input channel than the input port can transmit. The input port transmits cells from its input buffer responsive to a plurality of priority levels.      Each output port has an output buffer holding cells when the cells arrive faster from the input ports than the output port can transmit. The output port also transmits cells from its output buffer responsive to a plurality of priority levels. The backpressure signal circuit sends a signal from a congested output buffer through the switch fabric to those input port buffers which had immediately transmitted a cell to the output buffer so that the input port buffers cease transmission. In this manner, the ATM switch drops cells on a per-connection basis, rather than on cell priority level.

Abstract: A mechanism for mounting a forward pedal and a reverse pedal to a vehicle. The forward pedal is fixed to a primary shaft, and the reverse pedal is fixed to a secondary shaft. A control arm and control rod operatively extend between the primary shaft and atransmission. A linkage extends between the reverse pedal and the primary shaft for pivoting the primary shaft and shifting the control rod in reverse directions such that the transmission shifts to reverse modes when the operator engages the reverse pedal. The linkage includes a reverse arm coupled with the primary shaft, and a reverse link extending between the reverse arm and the reverse pedal. A bracket member fixed to a floor plate of the vehicle supports the primary and secondary shafts, and is fixed to the vehicle generally directly beneath the foot of the operator. The bracket member supports each shaft at at least two locations laterally spaced a substantial distance. Mating shapes are defined between the reverse arm and the primary shaft for fixing the primary shaft for rotation with the reverse arm. Mating shapes are also defined between the reverse shaft and reverse pedal for transmitting pivotal motion therebetween. The reverse link is confined in engagement with the reverse pedal and the reverse arm by abutment with the bracket member.

Title: Method and apparatus for automatically identifying key words within a document
Inventor: TURNEY PETER D
IPC: G06F17/30
Filed: 1998-05-04
Granted: 2006-11-14
Abstract: A trainable method of extracting keywords of one or more words is disclosed. According to the method, every word within a document that is not a stop word is stemmed and evaluated and receives a score. The scoring is performed based on a plurality of parameters which are adjusted through training prior to use of the method for keyword extraction. Each word having a high score is then replaced by a word phrase that is delimited by punctuation or stop words. The word phrase is selected from word phrases having the stemmed word therein. Repeated keywords are removed. The keywords are expanded and capitalisation is determined. The resulting list forms extracted keywords.

Abstract: A staple pulling plier of the type consisting of a pair of pivoting members having handles and jaws forming a head portion. The head portion has opposite side faces, and the jaws in a closed position define a substantially continuous post engaging top ridge. Pincer points are provided on the jaws adjacent the top ridge and are moved to a closed staple grasping position on closure of the handles. A fulcrum member isformed integrally with the head portion and projects from one of the opposite side faces of the head portion, the fulcrum member defining an upper edge extending in a plane substantially normal to the post engaging top ridge of the jaws. When the bight of a staple is held by the pincer points, the two legs of the staple and the joining bight are in a plane normal to the post engaging top edge of the head portion. When the staple has been driven into a post to secure a horizontal strand of the fence, its plane is usually vertically disposed. Thus, as the plier is swung in a direction coinciding with the plane of the staple, the upper edge of the fulcrum member engages the post, and pressure can be applied in an up or down direction to more effectively withdraw the staple.

Title: Method for forming a non-uniform interface adjacent ultra hard material
Inventor: KESHAVAN MADAPUSI K
IPC: E21B10/56
Filed: 1999-02-12
Granted: 2005-08-23
Abstract: A non-uniform interface is formed between a polycrystalline ultra hard material layer and a cemented tungsten carbide substrate, or a polycrystalline ultra hard material layer and a transition layer, or a transition layer and a substrate of a cutting element.  A first sheet made from an intermediate material is formed and embossed on one face forming a non-uniform pattern raised in relief on the face. The embossed sheet is placed on a face of a presintered substrate. An ultra hard material sheet is formed and embossed, forming a non-uniform face complementary to the non-uniform face on the sheet of intermediate material.  The ultra hard material sheet is placed over the intermediate material sheet so that the complementary faces are adjacent to each other. The assembly of substrate and sheets is sintered in a HPHT process. The sintering process causes the first sheet to become integral with the substrate and results in a substrate having a non-uniform cutting face onto which is bonded a polycrystalline ultra hard material layer. Embossed transition material sheets may be employed between the ultra hard material sheet and the first sheet to form transition layers with uniform or non-uniform interfaces.
