Title: Orthopedic screw and method
Inventor: FALLIN THOMAS WADE
IPC: A61B17/86
Filed: 2001-04-03
Abstract: A screw, driving device, and method are provided for repairing a tissue injury of a patient, such as a meniscal tear in a knee or osteochondritis dissecans. The screw has a root, a distal section having a narrowing cross section toward the distal end, and a thread along at least a portion of the root between the proximal end and the distal end. Along a leading section extending from the distal end, the helical pitch is substantially constant; along a trailing section between the leading section and the root's proximal end, the helical pitch decreases. The substantially constant pitch along the leading section assists in preventing a stripping of the helical section. At the proximal end is a head having a diameter greater than a major root diameter of the central section. The head is for improving the tissue retention characteristics of the screw.

Title: Polymeric dispersants prepared from copolymers of low molecular weight polyisobutene and unsaturated acidic reagent
Inventor: HARRISON JAMES J
IPC: C10M129/72
Filed: 2002-10-10
Abstract: This invention is directed to a new low molecular weight copolymer (The PIB/UAR copolymer) that may be prepared by reacting a low molecular weight polyisobutene (PIB) having less than about 32 carbon atoms with an unsaturated acidic reagent in the presence of a free radical initiator. No chain transfer agent is required to prepare the low molecular weight PIB/UAR copolymer. The PIB/UAR copolymer may be useful as is, or as an intermediate for (1) polysuccinimides, (2) detergents or dispersants for tube oil or fuels, (3) pour point depressants and (4) surface sizing agents for paper.      The PIB/UAR copolymer may be used by itself or as the ester, amide, imide or metal salt derivative of the PIB/UAR copolymer. The PIB/UAR copolymer may be liquid at ambient temperature.
Patent CA-2408445-A1 (CA)
Title: Open gutter strainer
Inventor: NADDY WILLIAM
IPC: E04D13/064
Filed: 2002-10-17
Abstract: A device to be used as part of a new or existing rain gutter system, positioned between and joining an open-end gutter and the downspout, that utilizes the movement of flowing rain water to keep the system open and draining by floating and pushing nuisance debris to and out the low open end on to the invention. Removal of the low point end stop and repositioning the downspout connector eliminates the primary causes of pooling and build up of debris. Very steep smooth parallel bars, covering the top of a trough-shaped collector box, receive the effluence and separate the solids from the liquid, as the solids slide down and off the end while the liquids fall between the bars into the collector box for passage to the downspout connected at the bottom. The device enables the gutters to discharge at speeds and volumes consistent with collection minimizing the possibility of spillage while, at the same time, keeping the system open and flowing without the need for frequent hand cleaning. A versatile connector-adaptor enables connections to selected rectangular and round downspout pipe, rotating to accommodate the attitude of the pipe.
