Semiconductor Bridge (Scb) Detonator
US Patent:
5861570, Jan 19, 1999
Filed:
Apr 23, 1996
Appl. No.:
8/636626
Inventors:
Robert W. Bickes - Albuquerque NM
Mark C. Grubelich - Albuquerque NM
Mark C. Grubelich - Albuquerque NM
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
F42B 310
US Classification:
1022027
Abstract:
The present invention is a low-energy detonator for high-density secondary-explosive materials initiated by a semiconductor bridge igniter that comprises a pair of electrically conductive lands connected by a semiconductor bridge. The semiconductor bridge is in operational or direct contact with the explosive material, whereby current flowing through the semiconductor bridge causes initiation of the explosive material. Header wires connected to the electrically-conductive lands and electrical feed-throughs of the header posts of explosive devices, are substantially coaxial to the direction of current flow through the SCB, i. e. , substantially coaxial to the SCB length.
Reduced-Impact Sliding Pressure Control Valve For Pneumatic Hammer Drill
US Patent:
8176995, May 15, 2012
Filed:
Apr 16, 2009
Appl. No.:
12/424583
Inventors:
Yarom Polsky - Oak Ridge TN, US

Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
B25D 9/18, B25D 9/00
US Classification:
173114, 173 13, 173 17, 173 78, 173 79, 173 80, 91222, 91327, 91348, 251343, 251344, 251345, 137508
Abstract:
A method and means of minimizing the effect of elastic valve recoil in impact applications, such as percussive drilling, where sliding spool valves used inside the percussive device are subject to poor positioning control due to elastic recoil effects experienced when the valve impacts a stroke limiting surface. The improved valve design reduces the reflected velocity of the valve by using either an energy damping material, or a valve assembly with internal damping built-in, to dissipate the compression stress wave produced during impact.
Gas Powered Fluid Gun With Recoil Mitigation
US Patent:
8579209, Nov 12, 2013
Filed:
Nov 18, 2010
Appl. No.:
12/948801
Inventors:
Mark C. Grubelich - Albuquerque NM, US
Gerold Yonas - Albuquerque NM, US
Gerold Yonas - Albuquerque NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
B05B 1/26, B05B 1/34, B05B 7/32, F23D 11/24, F23D 14/28
US Classification:
239337, 239347, 239370, 239373, 239396, 239461, 239518
Abstract:
A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated. Examples of recoil mitigation devices include a cone for making a conical fluid sheet, a device forming multiple impinging streams of fluid, a cavitating venturi, one or more spinning vanes, or an annular tangential entry/exit.
Diversionary Device
US Patent:
6253680, Jul 3, 2001
Filed:
Feb 24, 1999
Appl. No.:
9/256812
Inventors:
Mark C. Grubelich - Albuquerque NM
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
F42B 300, F42B 1246
US Classification:
102334
Abstract:
A diversionary device has a housing having at least one opening and containing a non-explosive propellant and a quantity of fine powder packed within the housing, with the powder being located between the propellant and the opening. When the propellant is activated, it has sufficient energy to propel the powder through the opening to produce a cloud of powder outside the housing. An igniter is also provided for igniting the cloud of powder to create a diversionary flash and bang, but at a low enough pressure to avoid injuring nearby people.
