摘要： An initiator assembly having a base, first and second conductive elements, a first electrically insulating member and an energetic material. The first conductive element, which is configured to receive an electrical input, is coupled to the base and includes a tip. The first electrically insulating member is disposed over the tip. The second conductive element has a bridge that is disposed over the first electrically insulating member. The bridge is configured to vaporize in response to transmission of the electrical input from the tip of the first conductive element to the bridge. The energetic material is disposed over the bridge. Energy produced during vaporization of the bridge is transmitted to the energetic material to initiate at least one of a combustion event, a deflagration event and a detonation event in the energetic material. A method for operating an initiator assembly is also provided.

摘要： The invention deals with a detonation tube with improved separability from the processed broken stone designed as a double-layer or multi-layer detonation tube of an industrial non-electric detonator containing the active component of the detonator stored in an at least double-layered tubular body or package where the principle is that at least one layer of its body or package is made of magnetic material while the magnetic material is preferentially created as a mixture of the magnetic and non-magnetic main material component while the content of the magnetic main material component in individual layers of the body or package of the detonation tube is advantageously 2 to 60% of weight and the rest to 100% consists of the non-magnetic main material component, all related to the weight of individual layers, and the magnetic main material component is beneficially produced on the basis of magnetite —Fe3O4, or on the basis of ferrite with the general formula MeIIFe2O4, where Me represents Co, Mn, Ni, Ca, Cu, Zn, Mg, or ferrite with the general formula LnIIFe2O4, where Ln represents noble earth elements, or on the basis of noble earth elements in the oxidation degree II, or on the basis of ferric oxide in the modification γ-Fe2O3, or on the basis of powder iron, or on the basis of a magnetic alloy of iron or on the basis of a mixture or alloy containing the above mentioned magnetic partial components, where advantageous magnetic alloys of iron are alloys containing at least noble earth elements, or especially advantageous magnetic alloys of iron are alloys containing at least one noble earth element and B and/or Co or where alternatively the magnetic main material component is made on the basis of magnetically hard materials of the AlNiCo or FeCoCr type. The non-magnetic main material component is beneficially created on the basis of a plastic material, preferentially from the group of polymers or copolymers, mainly on the basis of substances from the PE, PP, PTFE plastic material group or ethylene copolymers with derivatives of methacrylic acid.

摘要： A method of coating the inner wall surface of a hollow body, the one end side of which is open and comprises there a free perimeter edge. The method involves covering or masking a region of the inner wall surface, applying an electric potential to the pin holder, the applying an electrolyte to the uncovered region of the inner wall surface, said electrolyte containing a coating material that has a low electrical resistance at the transition between the metallic material of the cylindrical wall of the pin holder and the material of another metallic component part.

摘要： An initiating element of non-primary explosive type comprising a confinement containing secondary explosive, having a first end adapted for ignition of the secondary explosive by igniting means, optionally via delay and flame-conducting pyrotechnic compositions, a second end adapted for delivering a detonation impuls and a intermediate portion in which the secondary explosive upon ignition is able to undergo a deflagration to detonation transition. At least a part of the secondary explosive is modified to give increased reaction rates at low pressures.

摘要： A method of fabrication of expandable polystyrene plastic ignition contai is disclosed which yields an electric squib case and an ignitor charge case which can be easily loaded with a pyrotechnic charge and an ignitor charge respectively, and when in combination, serves as the ignitor system for a high length to diameter flight motor.The method of fabrication employs expandable polystyrene beads in a first predetermined amount of polystyrene beads which are first pre-expanded to about three times their original size. A second predetermined amount of expandable polystyrene beads are combined with the pre-expanded beads; the combined beads are added to a mold of the desired shape; and the mold is placed in a steam chamber to expand the combined beads to form either the squib case or ignitor charge case. The squib case and the ignitor charge case when mated as an ignitor system for a rocket motor each has the weight, density, and strength to remain in tact during an ignition phase but subsequently breaks up into small pieces which does not inflict damage to propellant in the rocket motor or cause plugging of nozzle when in operation.

摘要： An impact sensitive high temperature detonator is disclosed. The detonator comprises an initiator charge of lead azide next to a thin casing wall at the input end, and a mass of finely divided refractory material adjacent to the initiator charge. The detonator can be initiated by a rounded firing pin, which indents the casing wall without puncturing it. In the event of misfire, the casing will remain intact, which facilitates safe removal of the detonator.
