Abstract: A toothed roller having a cylindrical body with circumferential rows of teeth fixed on the outer surface of the body. The rows of teeth are longitudinally spaced apart on the body. A cleaning ring is loosely mounted on the body between each adjacent pair of rows of teeth. Each cleaning ring has an inner diameter slightly larger than the outer diameter of the body and an outer diameter slightly smaller than the outer diameter of a row of teeth whereby when one portion of the cleaning ring abuts the body, the diametrically opposed portion of the ring is nearly level with the ends of the teeth so as to be able to push out material and debris caught between, and on, the rows of teeth.

IPC: A61K35/12
Filed: 1997-10-17
Granted: 2009-12-15
Abstract: A method of pretreating healthy donor's myoblast cultures with growth or trophic factors like basic fibroblast growth factor (bFGF) and with concanavalin A on transplantation to subjects suffering of myopathy like muscular dystrophy is disclosed and claimed. Recipient muscles show a higher percentage of functional cells, a four-fold increase, demonstrated by the higher incidence of dystrophin-positive fibers, and does not require previous preconditioning of recipient muscles b y irradiation or toxin administration. The recipient subjects were immunosuppressed with FK 506. When growing myoblasts with 20 .mu.g/ml concanavalin A or 100 ng/ml TPA for two to four days, migration of donor cells in recipient tissue was increased by 3 - 4 fold. Th is suggests that, when using primary cultures, metalloproteases are secreted by fibroblasts, resulting in a greater degradation of the extracellular matrix. Both metalloproteases and bFGF appear beneficial for the success of the transplantation. The use of recombinant myoblast expressing metalloproteases is also contemplated.

Abstract: A laminate comprising two or more films (26, 28), at least one of the films being a coextended, multilayer film (26), wherein the laminate delaminates within the coextruded, multilayer film (26) when the laminate is subjected to a peel force ranging from 0.001 to 2.5 pounds per inch. The laminate adavantageously provides the lid (24) for a package and delaminates into a substantially gas-impermeable portion and a gas-permeable portion, with the gas-permeable portion being bonded directly to a product support member (12) of the package. In this manner, the gas-impermeable portion may be peelably removed from the package to allow atmospheric oxygen to enter the interior of the package. The gas-permeable portion may be provided by perforating the delaminatable, coextended film (26) and bonding such film to the support member (12) so that, when the laminate is caused to be delaminated within the perforated, coextruded film (26), the perforations are exposed to the ambient atmosphere, and thereby allow for rapid ingress of oxygen into the interior of the package.

Granted: 2005-08-02
Abstract: A reversibly deactivated, particulate catalyst in a hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through (i) a gas disengaging zone to remove gas bubbles from the slurry and increase its density, (ii) a downcomer which feeds the gas reduced, dense slurry into the bottom of a rejuvenating tube and applies a positive hydrostatic pressure to the tube, (iii) a catalyst rejuvenation zone in which a catalyst rejuvenating gas, which also acts as a lift gas, contacts the catalyst in slurry to form a catalyst rejuvenated slurry and, (iv) back into the slurry body. Removing gas bubbles prior to rejuvenation improves the rejuvenation efficiency and the downcomer reduces the amount of rejuvenation gas required to maintain slurry circulation through the tube.

Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mining technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
