Nov 29, 2005

Appl. No.:

11/288371

Inventors:

George N. Hennings - Ridgecrest CA, US
Richard K. Reynolds - Calistoga CA, US
Christopher J. Nance - Middletown CA, US

Assignee:

Reynolds Systems, Inc. - Middletown CA

International Classification:

F42C 19/12
F42B 3/10

US Classification:

1022025, 1022021, 1022029, 10220214

Abstract:

An igniter assembly with a housing, an initiator, an input charge, a first barrier, a second barrier, and an output charge. The input charge is formed of a secondary explosive and disposed adjacent the initiator. The first barrier cooperates with the housing to form a chamber into which the input charge is received. The second barrier is disposed on a side of the first barrier opposite the input charge and combusts in response to energy released during detonation of the input charge. The output charge is formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier. The output charge can combust in response to energy released during combustion of the second barrier. The housing and the first barrier cooperate to isolate the output charge from heat and pressure generated by the input charge if the input charge is cooked-off.

US Classification:

1022028, 1022025, 1022029, 361247

Abstract:

A switch device having a base, a first electrically conductive pad coupled to the base, a second electrically conductive pad coupled to the base, a first electrically conductive projection and a second electrically conductive projection. The second electrically conductive pad is spaced apart from the first electrically conductive pad by a first predetermined distance. The first electrically conductive projection is coupled to the first electrically conductive pad and extends into the first gap. The second electrically conductive projection is coupled to the second electrically conductive pad and extends into the first gap. The second electrically conductive projection is spaced apart from the first electrically conductive projection by a second predetermined distance. The first and second electrically conductive projections form an electrical interface.

US Classification:

1022027, 1022028, 1022025, 10220214, 361247

Abstract:

A device having an initiator and an integrated planar switch. The initiator has a base, an initiating element that is coupled to the base, a first element pad, which is electrically coupled to a first side of the initiating element, and a second element pad, which is electrically coupled to a second side of the initiating element opposite the first element pad. The integrated planar switch has a source pad and a return pad. The source pad is coupled to the base and is spaced apart from the first element pad by a first gap distance to define a first gap therebetween. The return pad is coupled to the base and is spaced apart from the second element pad by a second gap distance to define a second gap therebetween.

Inventors:

Christopher J. Nance - Middletown CA, US

Assignee:

Reynolds Systems, Inc. - Middletown CA

International Classification:

F42B 3/12
F42C 11/00

US Classification:

1022029, 1022027, 1022025, 10220214

Abstract:

An initiator that includes a header body, an insulating spacer, an initiator chip, a plurality of terminals and a plurality of contacts. The insulating spacer is coupled to the header body. The initiator chip that forms at least a portion of an exploding foil initiator and includes a plurality of electric interfaces. The initiator chip is secured to a side of the insulating spacer opposite the header body. The terminals extend through the header body. The contacts electrically couple the electric interfaces to the terminals. The cover is coupled to the header body and cooperates with the header body to house the insulating spacer, the initiator chip and the contacts. A method for forming an initiator is also provided.

International Classification:

F42B 3/10

US Classification:

1022027, 1022025, 1022029

Abstract:

An initiator that includes a substrate, an exploding foil initiator and a first switch. The exploding foil initiator coupled to the substrate and includes a bridge and a first bridge contact. The first switch has a first contact and a first insulator. The first contact is coupled to the substrate and spaced apart from the first bridge contact by a gap. The first insulator is disposed in the gap. The first switch is operable in an actuated mode in which electrical energy transmitted between the first contact and the first bridge contact is transmitted through the first insulator.

US Classification:

1022025, 1022021, 1022029, 10220214

Abstract:

An igniter assembly that includes a housing, a secondary explosive input charge, a pyrotechnic output charge and a barrier system that is disposed between the input charge and the pyrotechnic output charge. The barrier system shields the pyrotechnic output charge from energy released by the input charge to prevent the output charge from being cooked-off or initiated unless the input charge is detonated.
