Patent CA-2166661-A1 (CA)
Inventor: SFERRAZZA RANDALL A
IPC: B29B17/02
Filed: 1996-01-05
Abstract: Process and system for reclaiming polymeric fibers (e.g., nylon) from post-consumer carpeting includes shredding the post-consumer carpeting into strips, dismantling the carpet strips to form a mixture of the fibers to be reclaimed and the backing material to be discarded, and then separating a substantial portion of the fibers from the backing material. Preferably, the carpet strips are dismantled by impacting the strips of carpeting against an anvil structure with hammer elements using, e.g., a hammermill. A secondary reclamation system is provided whereby the separated backing material which may contain some fibers bound thereto is subjected to secondary dismantling and separation operations. The fractions obtained from the primary and secondary separation operations containing predominantly the polymeric fibers may thus be combined so as to form a process discharge stream which can be pelletized and/or baled as desired.

Patent CA-2177849-A1 (CA)
Title: Method for inputting and load balancing seismic data for seismic processing on a multiprocessor computer
Inventor: SCHOEN ERIC J
IPC: G01V1/28
Filed: 1994-12-01
Abstract: This invention provides a method for inputting  seismic trace data to a seismic processing program running on a massively parallel processor (MPP) and for balancing the computational workload of individual processors.  The MPP, consisting of a plu-rality of individual processing nodes con-nected by a data and control communica-tions network, is treated as a bipartite sys-tem of "operator" nodes and "input" nodes. Opertor nodes apply mathematical oper-ators to transform seismic data.  Groups of seismic traces are loaded into the in-put nodes.  The input nodes examine the data to determine which regions of the seis-mic survey are covered by the traces and how many traces cover each bin.  The in put nodes then broadcast to all operator nodes a compact description of the trace coverage. The operator nodes then retrieve traces from the input nodes, using efficient data transfer mechanisms of the data net-work.  The input nodes can be seen to serve as a distributed, content-addressable data cache.  All nodes use the information in each broadcast to determine how many bins will be assigned to each "operator" node that will process the prestack data to produce poststack data.  The bin assign-ment is designed to equalize the number of traces that each opertor node processes.  Thus, the invention provides a means for maximizing the efficiency with which an MPP can perform seismic migration processing, and is applicable to wide variety of MPPs and processing algorithms.

Title: Fiber reinforced thermoplastic structural member
Inventor: HEIKKILA KURT E
IPC: B29C48/90
Filed: 1996-06-03
Abstract: In the manufacture of a structural member comprising a thermoplastic composite core with an exterior reinforcing layer, the core member is initially extruded in the shape of a profile. The profile is then contacted with reinforcing fiber and resin to form the exterior reinforcing layer. The exterior thermosetting layer is cured to form a reinforcing layer. The structural member is preferably manufactured using a pultrusion method in which a tractor device is used to provide linear movement of the profile from the extrusion head to the exterior coating operation. The fiber-reinforced thermoset is coated on the entirety of the exterior of the profile or is applied only on a portion of the profile requiring reinforcement in a defined load-bearing direction. The preferred thermoplastic core comprises a polymer-fiber composite material. Such a structural member has significantly improved Young's modulus providing strength for applications such as telephone poles, electric poles, electric lighting poles, boat mast or keel applications, lumber replacements, structural members used in window and door manufacture, etc.
Patent CA-2178434-A1 (CA)
Inventor: GLASGOW JAMES A
IPC: B01D17/028
Filed: 1996-06-06
Abstract: A skimmer/coalescer system includes a skimmer which skims a two-component liquid from the surface of a liquid mixture in a tank, and a pump which pumps the skimmed liquid to a coalescer for separating and collecting a lower density liquid component from the mixture and returning the rest of the liquid to the tank.      The skimmer includes a housing submerged below the liquid surface in the tank, an outlet operatively connected to the pump and an intake which supplies liquid to the housing by gravity. The intake includes a vertically movable inlet which remains adjacent the liquid surface regardless of liquid level changes in the tank, thereby to skim near the surface where the lower density liquid dominates, and to enhance skimming efficiency. The skimmer also includes a sensor inside the submerged housing which cooperates with the intake to expand or contract the size of the inlet to increase or decrease in-flow to the housing, respectively, depending on whether the liquid level in the submerged housing is receding or raising. This maintains consistent and continuous liquid flow through the system during operation and minimizes the possibility of pump damage.
