Title: Treating metal surfaces to enhance bio-compatibility and/or physical characteristics
Inventor: AL-LAMEE KADEM GAYAD
IPC: A61F2/04
Filed: 1998-06-03
Abstract: A metal, glass or ceramics surface is treated to enhance its compatibility with biological material such as blood or blood related products. Treatment involves covalently bonding to the surface by means of a catalyst functional molecules, each of which has at least one alkoxysilane group which can form at least one first covalent bond by reaction with the oxide or hydroxide of said surface and at least one other group which can participate in free-radical polymerisation. Free-radical polymerisation from said functional molecules in then effected to build bio-compatible and/or hydrophilic polymer chains. The compatibility of the metal surface with biological material may be further improved by bonding bio-active molecules, such as heparin or heparin-derived molecules to the polymer chains. Suitable metal surfaces are those of medical devices such as heat exchangers, coronary and peripheral stents and guide wires used in angioplasty.
Patent CA-2295769-A1 (CA)
Title: Moisture sensor for ore concentrates and other particulate materials
Inventor: ROSENBLUM EPHRAIM
IPC: G01N11/10
Filed: 1998-05-26
Abstract: The present invention is concerned with a moisture sensor for measuring the moisture content of particulate material like ore concentrates. The sensor comprises a body having one end to be buried within the bulk of the particulate material and the other end coupled to a force transducer. The force transducer itself is coupled to display means, so that when a conveyor containing the ore concentrate is in operation, a signal is generated from the force transducer and displayed as a result of the drag force exerted by the particulate material on the body. The moisture content may therefore be determined either by means of a calibration chart, or by the output of a calibration computer.
