摘要： A separatory device is disclosed wherein a bundle of hollow fibers have their end portions potted in a polyurethane tube-sheet, said polyurethane consisting of an isocyanate-containing prepolymer which is non-catalytically crosslinked with a polyol. The resulting tube-sheet has demonstrated an unexpected degree of adherence to the fibers. In addition, essentially no adverse toxicity effects are encountered in biomedical applications of said device.

摘要： The invention provides compositions and methods for storage of biomolecules. The biomolecules are stored via absorption to a substrate. Absorbed biomolecules can be eluted or recovered from the substrate at a future time, and optionally be subjected to a subsequent analysis or application. Biomolecules absorbed to a substrate for storage may also optionally be preserved, i.e., the absorbed biomolecule is resistant to or resists degradation.

摘要： An antifuse circuit includes a terminal, an antifuse, and a select transistor. The antifuse is coupled to the terminal and has an associated program voltage. The select transistor is coupled to the antifuse and has a gate terminal coupled to receive a first select signal. The select transistor operates in a snapback mode of operation in response to an assertion of the first select signal and the program voltage at the terminal.

摘要： An optional removable front grip usable with any firearm having a barrel shroud formed with a row of regularly spaced openings on its underside. Such openings are routinely provided to ventilate the barrel. The invention front grip is hollow and is provided with a set of lugs which engage any three adjacent barrel shroud ventilation openings to thereby accommodate shooters having different arm lengths. One of the lugs is a locking lug which is operated easily by a screwdriver inserted through the hollow grip.
