Title: Process for preparing carbon nanotubes
Inventor: DESILETS SYLVAIN
IPC: C01B31/02
Filed: 2001-05-10
Abstract: Carbon nanotubes are formed on carbon paper by first depositing a metal catalyst on the carbon paper, and passing a feedstock gas containing a source of carbon over the substrate while applying an electrical current thereto to heat the substrate sufficiently to generate a reaction between the catalyst and the feedstock gas. Alternatively, inert gas under pressure is passed through a tubular metal cathode while passing an electric current through the cathode to produce a plasma of fine catalyst particles which are deposited on a porous carbon substrate, and a feedstock gas containing a source of carbon is passed over the substrate to cause a reaction between the catalyst and the carbon source resulting in the formation of carbon nanotubes.

Title: Retractable needle and syringe combination
Inventor: GARVIN DAVID M
IPC: A61M5/34
Filed: 2001-05-17
Abstract: A combination hypodermic syringe and needle device in which the needle is retracted inside the syringe after completion of the injection. The device requires only one hand for operation wherein increasing the pressure on the plunger initiates an automatic retraction of the needle into the syringe. In operation, a collet is expanded and a spring biased needle retractor is engaged in response to the forward movement of a plunger. The forward end of the barrel carries a wedge which forces the collet to expand upon forward movement of the collet. A vent located in the plunger allows air to escape from the interior of the plunger as the needle assembly is retracted.
