摘要:
A medical device comprising a biomaterial formed from a polymer comprising urethane groups, urea groups, or combinations thereof, and sacrificial moieties that preferentially oxidize relative to other moieties in the polymer.
摘要:
The present invention provides electronically conducting polymer films formed from formulations of pyrrole and an electron acceptor. The formulations may include photoinitiators, flexibilizers, solvents and the like. These formulations can be used to manufacture multichip modules on typical multichip module substrates, such as alumina, fiberglass epoxy, silicon and polyimide. The formulations and methods of the invention enable the formation of passive electronic circuit elements such as resistors, capacitors and inductors in multichip modules or printed wiring boards.
摘要:
A new Vehicle-Mounted Snow Plowing System for improving the driveability of a vehicle in snow by clearing snow away from the intended path of the wheels of the vehicle. The inventive device includes a vehicle mount removably mounted to the front of a vehicle, and a pair of snow deflector assemblies removably mounted to the vehicle mount. The snow deflector assemblies are mounted ahead of and in line with the front wheels of the vehicle. Furthermore, the snow deflector assemblies are moveable between a lowered, operative position and a raised, stowed position.
摘要:
A filter bag support member for fastening a filter bag to an apertured bag header plate member disposed between the dirty gas inlet and the clean gas outlet of a filter bag housing comprising a flow-through venturi-like tube having one end releasably fastened to the plate member and a clamp at the other end receiving the filter bag in supporting sealed relation.
摘要:
A heart model provides a simulative environment for lead implantation and affixation. In one embodiment, removable silicone plugs are provided at appropriate locations so that an inserted lead can be affixed to the plugs with a helical tip. A simulative venous structure is provided that has increased lubricity to facilitate the insertion and manipulation of the lead.
摘要:
Compounds that include silicon-containing groups, and optionally urethane groups, urea groups, or combinations thereof (i.e., polyurethanes, polyureas, or polyurethane-ureas), as well as materials and methods for making such compounds.
摘要:
The present invention is related to the modifying of substrates with multiple modifying agents in a single continuous system. At least two processing chambers are configured for modifying the substrate in a continuous feed system. The processing chambers can be substantially isolated from one another by interstitial seals. Additionally, the two processing chambers can be substantially isolated from the surrounding atmosphere by end seals. Optionally, expansion chambers can be used to separate the seals from the processing chambers.
