Acid Assisted Cold Welding And Intermetallic Formation And Dental Applications Thereof

View page
US Patent:
6375894, Apr 23, 2002
Filed:
May 9, 1995
Appl. No.:
08/437650
Inventors:
David S. Lashmore - Lebanon NH
Moshe P. Dariel - Rockville MD
Christian E. Johnson - MIddletown MD
Menahem B. Ratzker - Silver Spring MD
Anthony A. Guiseppetti - Frederick MD
Frederick C. Eichmiller - Ijamsville MD
Glenn L. Beane - Plymouth NH
David R. Kelley - Martinsburg WV
Assignee:
The United States of America as represented by the Secretary of Commerce - Washington DC
American Dental Association Health Foundation - Gaithersburg MD
International Classification:
A61C 500
US Classification:
419 64, 264 16, 433226, 4332281
Abstract:
A metallic composite solid, containing alloys and/or intermetallics, is formed by compacting at moderate pressure a mixture of powder particles, foils or sheets at a temperature close to room temperature, well below the melting temperature of the constituent components and without the addition of low melting metals such as mercury, indium or gallium acting as a sintering agent. This low temperature consolidation of the powder mixture is enhanced by having the surface oxide of the powder particles removed, prior to consolidation, and/or by coating the particles with an oxide-replacing metal such as silver or gold. The coating process may be replacement reactions, autocatalytic reduction or electrolytic reduction. The composite formation is assisted by the addition of a liquid acid such as fluoroboric acid, sulfuric acid, fluoric acid, adipic acid, ascorbic acid, or nitric acid. A preferred embodiment of the process for metal solid composite formation is a process for forming dental restorative materials at ambient temperatures and under pressure exerted by manual dental instrumentation.

Impactor And Paste Feeder

View page
US Patent:
6991459, Jan 31, 2006
Filed:
Jul 22, 2003
Appl. No.:
10/625476
Inventors:
David S. Lashmore - Lebanon NH, US
Assignee:
Innovative Dental Technologies, Inc. - Lebanon NH
International Classification:
A61C 3/08
US Classification:
433 83, 433150, 173112
Abstract:
An impactor for safely, efficiently, and effectively placing mercury-free dental restorations in a cavity of a patient's tooth, the impactor having a housing, anvil, hammer, solenoid or other transducer, end cap, source of restoration paste, and paste feeder tube for condensing mercury-free paste in the cavity. The impactor provides periodic impulses by activating the solenoid, causing the hammer to strike the anvil. The anvil is forced into contact with the paste, thereby condensing the paste into a high-density metal or other material suitable for dental restoration. (Also disclosed is a solenoid or other transducer having a “T” shaped hammer which strikes an anvil. ) The solenoid or other transducer can be used to compact or strike any surface. The paste feeder may be incorporated into the impactor or alternatively be a separate hand operated device.

Systems And Methods For Controlling Chirality Of Nanotubes

View page
US Patent:
8057777, Nov 15, 2011
Filed:
Jul 25, 2008
Appl. No.:
12/180300
Inventors:
David S. Lashmore - Lebanon NH, US
Craig Lombard - Concord NH, US
Assignee:
Nanocomp Technologies, Inc. - Concord NH
International Classification:
D01F 9/12
US Classification:
4234473, 4234471, 977843
Abstract:
A system is provided that can be utilized to generate nanotubes with substantially similar chirality. The system provides a resonant frequency, keyed to a desired radial breathing mode linked to the desired chirality, that causes a template of catalysts particles or nanotubes to oscillate at the provided resonant frequency, so as to stimulate growing nanotubes to oscillate at a corresponding resonant frequency. This resonant frequency can be a result of a high frequency field or the natural heat radiation generated by the system.
