Title: Process and apparatus for producing curved hollow bodies of thermoplastic material
Inventor: KLEIN MARTIN
IPC: B29C49/42
Filed: 1998-06-25
Abstract: In a process and apparatus for producing elongate curved hollow bodies at least partially comprising thermoplastic material  a preform is extruded from an extrusion system head and engaged by a gripping means. The preform is moved by the gripping means into the region of a guide stencil  disposed above the mold cavity of a mold portion of a divided blow molding mold and  introduced into the mold cavity by a simultaneous  downward movement  of the gripping means  and a movement following the configuration of the guide stencil. The guide stencil has two mutually opposite walls,  the  spacing of which  increases  in  an upward direction and the spacing of which at the bottom of the guide stencil  approximately corresponds  to  the maximum width  of the mold cavity.  The  preform  is  thus  guided towards  the mold cavity by the walls,  acquiring its  definitive  orientation with respect thereto by virtue of such guidance, passing through a lower opening in the guide stencil  into  the  mold  cavity.  The mold  is  closed  and  the  preform expanded therein by an increased internal pressure in the preform.

Title: Method and apparatus for symbol decoding using a variable number of survivor paths
Inventor: ANDERSON JOHN B
IPC: H04B1/10
Filed: 1996-12-23
Abstract: A low complexity, high performance trellis decoder adapts the complexity of the trellis decoding process based on a current condition of the communications system.      A trellis structure of nodes and branches is developed to decode the sequence of symbols received over a communications channel. Each set of nodes in the trellis represents the possible values of a received symbol at one time instant. Each branch defines a specific transition between nodes at different time instants, and each branch has an associated branch metric or weight.      A linkage of branches between the nodes and the trellis defines a path through the trellis that represents one possible symbol sequence, and an accumulated metric/weight is generated for each possible path through the trellis. A variable number M survivor paths through is determined based on their accumulated path metric/weights. The value of the variable M depends on the current condition of the communications system. Once the value of M is adapted to the current condition, the sequence of received symbols is decoded using M survivor paths through the trellis.

Patent CA-2247245-A1 (CA)
Inventor: BITWINSKI JOAN
IPC: D03D3/02
Filed: 1997-02-03
Abstract: Woven fabric sleeve (10) is comprised of interwoven glass fibre yarns or similar mineral or ceramic fibre yarns, and hybrid yarns or wire utilised as fill (weft) yarns (12). The fill (weft) yarns (12) preferably consist essentially of glass or ceramic fibres with resiliently settable polymeric materials and/or resilient formable wires or combinations thereof. The wires or hybrid yarns are resiliently set to form resilient hoops yieldably imparting to the fabric side edges a tendency to move into adjacent or overlapping relationship. In one form of the method of making a sleeve, the hybrid fill (weft) yarns (12) are resiliently set by placing the woven fabric in a folder, applying heat to cause the fill (weft) yarns (12) to assume a set in the wrap around or folded condition and then cooling so that the product is resiliently maintained in the set condition. In an alternative method of making the product, the product is woven on a shuttle loom and one or more wires are used as fill (weft) yarns (12). The wires are fed from pretensioned spools. The tension on the spools of wire imparts a resilient set which biases the side edges of the fabric into adjacent and overlapping relationship.

Title: Duplicated home location registers in a mobile radio system
Inventor: LINDQUIST JAN
IPC: H04W24/02
Filed: 1997-04-29
Abstract: A pair of home location registers (HLRs) are associated with each other by assigning two capability codes. A first capability code is utilized to provide system support by one of the HLRs whenever the other HLR fails. The second capability code is utilized to constantly update each other's database with the latest subscriber information. Whenever a particular HLR fails, the associated Signal Transfer Points (STPs) reroutes the incoming signals intended for that failed HLR to its mate HLR. The mate HLR compares the received signals1 destination point code with its first capability code to determine whether it is allowed to process this signal.      If there is a match, the mate HLR automatically and transparently processes the received signal without service interruption or delay. Whenever one of the HLRs receives a new subscriber data, the same data are communicated to the other HLR by using its second capability code as the destination address.
