Abstract: The present invention relates a novel hemostatic wound dressing, preferably comprising chitosan and an oxygen carrier such as a perfluorocarbon, and methods to treat hemorrhaging wounds and MRSA infections. The present invention helps with coagulation/clot formation as well as providing oxygen to the wound, all while being cost effective and competitive with current hemostatic dressings.

Abstract: A self-grounding soldering tip having a spring which serves for connecting the soldering tip to a heater bobbin for establishing a secure grounding of the soldering tip. A bobbin tube extends within the heater bobbin for removably retaining the soldering tip within the bobbin. The connection between the spring and bobbin tube provide tip-to-ground continuity. Moreover, the contact surfaces of the spring and bobbin tube are wiped clean upon plug-in and plug-out. The spring and bobbin tube are located in a cooler area of the soldering iron to slow down the rate of oxidation. Also, the spring and bobbin tube are made of the same or compatible materials, e.g., stainless steel, to prevent reactions that normally occur between incompatible metals.

Abstract: A disposable solder receiving capsule for a hand held vacuum solder extracting desoldering tool is formed of an outer tube which is closed at one end by a porous filter and has an opening at its opposite end, and a hollow solder collection chamber part, having a tubular member with an open end and which is closed with respect to the passage of solder therethrough at an opposite end, forming a solder receiving space within it. The solder collection chamber part is concentrically positioned within the outer tube with an air plenum disposed between the closed end of the chamber part and the filter and with at least one air channel extending the length of solder collection part for providing a path for gases entering the open end of the outer tube to the plenum and the filter that is separated from the solder receiving space. For facilitating solder reclamation, the capsule can be formed entirely of materials which are shape-sustaining when exposed to a temperature of 400° F.
