Title: Method and apparatus for reinforcing a fiber producing spinner
Inventor: SNYDER JAMES G
IPC: C03B37/04
Filed: 1996-02-19
Abstract: A method and apparatus are provided for extending the life of spinners by means of reinforcement which comprises a plurality of arms secured to the bottom wall of a spinner either individually or via an annular plate from which the arms extend. The reinforcement applies a radially inward force on a flange extending from the top or center of an outer sidewall of the spinner. The arms exert the radial force as the result of offset cams, due to a prestressed condition which is released after the reinforcement is installed in a spinner or otherwise. If the spinner includes both a center flange and an upper flange, the reinforcement may be installed to engage the center flange with gussets interconnecting the center flange and the upper flange at least at locations corresponding to the reinforcement to thereby provide reinforcement for both flanges. If the reinforcement is formed integrally as an annular plate with arms extending therefrom, the flange to be directly reinforced can be notched to receive the reinforcement by a bayonet coupling motion.

Abstract: A positioning tool (1) has an elongated cylindrical section (15) for reversibly engaging an acetabular cup (2), which is insertable through a pos-terior opening (28) in the cup. The outer diameter of a proximal portion of the cylindrical section (15) is ex-pandable to engage the inner wall (30b) of the cup in an interference fit to prevent movement of the cup rel-ative to the tool and hold the cup in engagement with the tool to move the cup with movement of tool to place the cup for implanting at a desired po-sition. The expanded portion of the tool may be contracted to release it from the cup after implantation. The proximal portion of the tool compris-ing the cylindrical first section (15) and tapered section (19), which is at-tached to the distal portion and sepa-rated therefrom by a partial transverse slot (22). Third section (15) is di-vided into semicircular sections (34, 35) by a diametrical vertical slot (20) therebetween. Diametrically opposite quadrants (29a, 29b) of the semicircular sections (34, 35) further contain elongated slots (26, 27) therethrough which are perpendicular to the vertical slot (20) and spaced from the edge (57) of the cylinder by a thin section (25).

Title: Hardware assisted modify count instruction
Inventor: LOWE ROBERT B JR
IPC: G06F9/302
Filed: 1994-03-24
Abstract: A circuit that enhances the performance of the execution of a read-modify-write instruction type. The circuit provides hardware detection and decoding of various options specified by the instruction and greatly improves the performance and conserves space within a micro code control store (14). The circuit also detects anomalous cases and reports them to micro-code for special handling. The detection of the anomalous cases occurs dynamically and in parallel to instruction execution, thereby improving performance. Resulting condition codes are also provided simultaneously to the control program. The circuit operates in concert with a micro-code controlled mechanism to read a memory variable and, based on the specification of the instruction of the circuit selectively adds 1, subtracts 1, adds a 16-bit mask specified by the instruction, or subtracts the 16-bit mask, and returns the result to a central processor (12). Anomalous conditions that include overflow, invalid mask specification, and a special exchange option are all simultaneously detected and reported to the micro-code.

Title: Method for the production of silicium metal, silumin and aluminium metal
Inventor: STUBERGH JAN
IPC: C25C3/36
Filed: 1995-06-02
Abstract: The present invention concerns a procedure for continuous or batch production in one or possibly more steps in one or more furnaces of silicon (Si), possibly silumin (AlSi alloys) and/or aluminium metal (Al) in the required conditions in a melting bath, preferably using feldspar or feldspar containing rocks dissolved in a fluoride and process equipment for implementing the procedure. Highly pure silicon is produced by electrolysis (step I) in a first furnace comprising a replaceable carbon anode (3) located at the bottom of the furnace and a carbon cathode (1) located at the top of the furnace. For the production of silumin the Si-poor residual electrolyte from step I is transferred to a second furnace and aluminium metal is added (step II).      Aluminium metal is produced in a third furnace (step III) by electrolysis after Si has been removed in step I and possibly in step II. The present invention also concerns the production of silicon, possibly silumin and/or aluminium by using process equipment comprising two or more furnaces integrated to form one unit with (an) intermediate partition wall(s) which is/are designed to transfer the electrolyte from one furnace to another.
Patent CA-2192683-A1 (CA)
Inventor: WINGE STEFAN
IPC: C07K1/34
Filed: 1995-06-22
Abstract: The present invention relates to a method of virus-filtering a solution that contains at least one macromolecule, by virtue of the total salt content of the solution lying in the range of from about 0.2 M up to saturation of the solution with the salt concerned. The inventive method reduces the residence time and the extent to which the solution need to be diluted, and optimizes the yield when virus-filtering primarily proteins, polysaccharides and polypeptides. The reduction in virus content is at least as good as with conventional techniques where the total salt content is low. The present invention facilitates virus filtration with the aid of the so-called "dead-end" technique, which affords several process and economic advantages in comparison with the tangential virus-filtering technique normally used. When virus-filtering the plasma protein factor IX, the yield obtained in the virus-filtering stags is increased from about 70% to above 95%, by raising the salt. content of the solution in accordance with the present invention.
Patent CA-2196164-A1 (CA)
Inventor: METEER CHARLES L
IPC: B29C70/58
Filed: 1995-07-27
Abstract: A syntactic structural foam product (10) in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres (11, 12) and dry resin powder (14), of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. Resin powder collected as a waste by-product from resin coating materials can be recycled in the production of the desired product. The foam product is produced by first intermixing the microspheres and powdered resin by physical agitation of the mixture and depositing the mixture as a layer over a surface having a release agent thereover within a dimension defining region between boundary members and then supplying heat with or without pressure to the layer at a temperature and for a time period sufficient to effect a melting of the resin powder and thereafter cooling the resin in a hardened condition to integrate the mixture into the product desired after which the product is withdrawn from the forming zone. Reinforcing elements such as glass or carbon fibers (15) can be selectively included in the mixture for predetermined desired physical and mechanical properties.

Title: Treatment of tissues to reduce subsequent response to injury
Inventor: SLEPIAN MARVIN J
IPC: A61K41/00
Filed: 1995-10-11
Abstract: An exogenous stimulus is applied to tissues or cells which are at risk in a subsequent surgical procedure or other intervention which induces a response by the cells that minimizes reaction to the subsequent procedure. Stimuli can be chemical, physiological or physical. Examples include those stimuli known to induce expression of stress response proteins or heat shock proteins, especially heat shock protein 70 (hsp 70) and hsp 90, for example, exposure to heat or dilute hydrogen peroxide, or direct administration of exogenous heat shock proteins, or those stimuli which act to inhibit or reduce heat shock protein expression, for example, treatment with flavonoids. An amount effective to modulate levels of stress response proteins or reduce the endogenous response is administered, based on in vitro assays which are used to determine levels of heat shock proteins or which are experimentally determined to reduce cell proliferation, thrombus formation, and matrix deposition following subsequent exposure to a procedure. Procedures can be surgery, angioplasty, or abrasion. The method and compositions are also useful in mediating some disease processes, where the process involves undesirable migration.
