US Patent:

6470802, Oct 29, 2002

Filed:

Jun 20, 2001

Appl. No.:

09/885146

Inventors:

Barry T. Neyer - Cincinnati OH
Robert Tomasoski - Centerville OH
Robert Tetreault - Pointe-Claire, CA
George Papadopoulos - Dollard Des Ormeaux, CA

Assignee:

PerkinElmer, Inc. - Wellesley MA

International Classification:

F42B 310

US Classification:

1022025

Abstract:

A chip slapper including a substrate, a sticking layer on the substrate, a conductive layer on the sticking layer in the shape of two lands separated by a bridge portion between the two lands, a buffer material on the conductive layer, a protective coating on the buffer layer extending across at least a substantial portion of the two lands but absent from the bridge portion, and a flyer layer over the bridge portion. The buffer layer prevents migration of the material of the coating into the material of the conductive layer and vice versa and better adheres the flyer layer on the bridge portion where the coating is absent.

Robert Tomasoski - Centerville OH, US

International Classification:

F42B 3/18

US Classification:

1022021

Abstract:

An initiator including a housing adapted to be received in an igniter or rocket motor, at least one charge at a distal end of the housing, an electro-explosive device behind the charge for detonating the charge when subject to a voltage HV, and a pressure bulkhead behind the electro-explosive device. An electronic subsystem in the housing is connected to the electro-explosive device through the bulkhead and includes a lead for providing the voltage HV to the electro-explosive device to initiate it, and a switch in the lead which does not conduct if errant voltages are present on the lead to prevent initiation of the electro-explosive device until the correct voltage HV is present.

Feb 2, 1998

Appl. No.:

9/017283

Inventors:

Barry T. Neyer - Cincinnati OH
John T. Adams - Bellbrook OH
Robert J. Tomasoski - Centerville OH

Assignee:

EG&G Star City, Inc. - Miamisburg OH

International Classification:

F42B 310

US Classification:

1022027

Abstract:

A detonator with a base portion including a header wall terminating in a support surface; an initiator on the support surface; an explosive charge spaced from the initiator; and a cap having an interior top surface and an enclosure wall extending downward from the interior top surface and surrounding the initiator and the explosive charge. The wall terminates in a rim secured at a location along the header wall corresponding to the thickness of the initiator, the spacing between the initiator and the explosive charge, and the thickness of the explosive charge thereby ensuring that the explosive charge is in communication with the interior top surface of the cap.

International Classification:

F42C 1912
F42B 3198
F42B 312

US Classification:

102221

Abstract:

A disarmable firing module with a firing module housing having an opening therein; a detonator holder received in the firing module housing via the opening in the firing module housing, the detonator holder including a cavity therein; a detonator disposed in the cavity of the detonator holder; and a detonator electronics assembly housed within the firing module housing. The detonator holder is removably secured within the housing which allows the detonator to be separated from the detonator electronics assembly to disarm the firing module.

Assignee:

EG&G Star City, Inc. - Miamisburg OH

International Classification:

F42B 310

US Classification:

1022027

Abstract:

A detonator with a base portion including opposing electrical leads; an exploding foil initiator on the base portion, the exploding foil initiator including two conductive lands separated by a bridge portion therebetween; and a connecting barrel of a predetermined thickness on the exploding foil initiator for optimizing the spacing between the exploding foil initiator and an explosive charge and for robustly interconnecting the lands of the exploding foil initiator with the electrical leads of the base portion.
