Title: Softwall mining method and device
Inventor: PETERSON RANDALL D
IPC: E21C25/60
Filed: 1998-05-01
Abstract: Slurryable ore where the overburden (50) is unstable and subject to collapse is mined from substantially parallel elongated main trenches (60) connected by a perpendicular trench (66) at the bottom of the mineral seam. A plurality of softwall mining devices (20) supported by face equipment (22) is placed in the perpendicular trench (66). The devices slurry the mineral material and move into the mineral seam (56) as the overburden sloughs behind the mining devices. The subsided overburden (54) is supplemented as necessary with injected material.      Slurried mineral flows to the parallel trenches (60) for removal to the surface. After the softwall devices have advanced the length of the parallel trenches (60), the devices are withdrawn and placed in additionally developed trenches elsewhere in the ore reserve.

Title: Processes and systems for dynamically measuring switch traffic
Inventor: COX STEPHEN T
IPC: H04Q3/00
Filed: 1998-06-08
Abstract: A process and system is disclosed for determining automatically and dynamically the correct time segment during which a switch or components of a switch receive peak traffic from a communications network. The process collects traffic data regarding the usage of a selected switch or selected switch components. The traffic data is collected over a selected journalling period (e.g., 30 days), which is periodically updated with new traffic data to maintain a journal of the most recent 30 days of collected traffic data. Collected traffic data is filtered to remove aberrant or corrupting data. An average peak usage segment for all of the segments of the journalling period is selected from the remaining filtered traffic data. By regularly adding new data to and removing old data from the journal, the resulting moving window will reflect recent changes in peak usage. Regularly (e.g., daily) selecting the average peak usage segment detects such changes quickly, with the result that the process of the present invention dynamically reacts to and determines changes in the peak usage segment for particular switch components. Peak usage segments and associated traffic data determined and collected by the present invention result in improved network traffic engineering.

Title: Device for influencing the flow-through of plastic material which is heated such that it can flow through a housing
Inventor: BACHER HELMUT
IPC: B29C48/27
Filed: 1999-07-21
Abstract: The invention relates to a device for influencing the flow-through of plastic material which is heated such that it can flow through a housing (1), especially a filter device or a reversing device for the plastic material. The inventive device comprises a flow-through channel (2) which passes through the housing (1), and a piston (8) with a circular cross-section which, in a boring (7) of the housing (1), can be longitudinally displaced in a transversal manner with regard to the longitudinal direction of the flow-through channel (2). The piston (8) traverses the flow-through channel (2). An unslotted scraper ring is placed outside the housing (1) on a piston section (19) which projects out of said housing (1). Said scraper ring is held by a stop (25) such that the piston (8) can be displaced relative to the scraper ring (23). The inner diameter (d2) of the scraper ring (23) is less than the diameter (d0) of the boring (7) of the housing, and is also less than the diameter (d1) of the end (21) of the piston section (19), said end facing away from the housing (1), during the coolest operational state thereof. The scraper ring (23) is always pretensioned on the piston section (19) and thus reliably scrapes the leakage material off the piston (8) which is taken along by the piston when it protrudes form the housing (1).
