Title: Systems and methods for processing cellular rich suspensions
Inventor: DUFF DANIEL H
IPC: A61M1/26
Filed: 1991-12-06
Abstract: A processing system (30) separates a cellular rich suspen-sion (32) into a cellular first constituent (36) and cellular-free sec-ond constituent (38). The system (30) includes a separation zone (40) that receives the cellular rich suspension (32) and discharges the first (36) and second constituents (38). The system (30) coord-inates the flow of cellular rich suspension (32) into the separation zone (40) with the flow of cellular-free second constituent (38) from the separation zone (40) to get a desired nominal separation efficiency. The system (30) also recirculates the cellular first con-stituent (36) back into the zone (40). By continuously recirculat-ing the cellular first constituent (36) back into the separation zone (40), the system (30) can get and maintain a desired volume of the first constituent (36), despite the volume of cellular rich suspen-sion (32) that is processed. By continuously recirculating the cel-lular first constituent (36) back into the separation zone (40), the system (30) also can provide operating conditions within the se-paration zone (40) that maximize separation efficiencies but that, without the benefits of recirculation, could otherwise damage or traumatize the cellular first constituent (36).

Title: Abrasive article having precise lateral spacing between abrasive composite members
Inventor: CALHOUN CLYDE D
IPC: B24D11/06
Filed: 1992-12-29
Abstract: ABSTRACT OF THE DISCLOSURE              This invention relates to abrasive articles, and more particularly, to an abrasive article having a backing that carries abrasive composite members that have a precise lateral spacing and orientation.  It has long been recognized that the abrading surface of an abrasive article can be clogged or gummed by material worn from the workpiece.  One way this problem has been addressed is by applying the abrasive grains on a backing in a dot pattern or matrix pattern.  When abrasive grains are disposed in a pattern, pathways exist for abraded material to be removed. There is a need for an abrasive article that has abrasive members having a precise, lateral spacing and a consistent and desired orientation relative to the backing.          The present invention provides a method of forming an abrasive article comprising the steps of providing an embossed carrier web having a plurality of recesses formed in the front surface thereof; filling the recesses with an abrasive composite slurry that includes a plurality of abrasive grains dispersed in a hardenable binder precursor, hardening the binder precursor to form individual abrasive composite members, laminating a backing sheet to the front surface of the embossed carrier web. The resulting article includes a plurality of precisely spaced abrasive composite members, positioned in a predetermined pattern and orientation on a backing sheet.

Inventor: WILLIAMS RICHARD G C
IPC: H04L27/00
Filed: 1991-07-26
Abstract: A block of output symbols is generated, using quadrature amplitude modulation, from a block of input bits. The input bits are processed, using one or more redundant codes having a Hamming distance greater than one, to produce digital words which control the in-phase components and digital words which control the quadrature components of the output symbols. A group of bits generated by a single coding step supplies bits for both types of digital word, thereby enabling that coding step to process simultaneously a larger number of bits than would be the case if separate coding were used for producing the two types of word.
