Abstract:
An electromagnetic generator for a projectile having a magnetic core, a coil system, a race duct and an element moveable in the race duct relative to the magnetic core for altering the magnetic field. An ignitable charge is provided for generating propellant gases which propellant gases cause at least initial movement of the element in the race duct.
Abstract:
A piezoelectric energy source having a piezoelectric transducer mounted in a housing and a movable piston arranged in the housing to bias the transducer to provide a desired electrical output. The piston exerts pressure on the transducer in response to a pyrotechnic charge and is locked in a predetermined biasing position by a locking arrangement such that a constantly effective pressure is exerted on the transducer.
Abstract:
An electric fuze, especially for hand grenades, having a power source which is activatable by the effect of a force for supplying output power and a delay unit for delaying the ignition of a primer with respect to the time of activation of the power source. The delay unit has a variable time constant and includes an RC circuit formed of a plurality of series or parallel connected resistors and/or capacitors which are functionally connected with one another by electrical leads which leads are arranged to be open-circuited for the purpose of changing the delay time in a predetermined manner.
Abstract:
An electronic switch for projectiles includes a circuit with a source of electric energy which is switched in when the projectile is discharged. The circuit includes an adjustable time-delay device for the explosion of the projectile, a device for preventing muzzle burst, and a self-destruct arrangement. The exploding fuse is connected to the source of energy by an impact or a proximity switch. The self-destruct arrangement is settable by cooperating cells carried by the projectile and by the barrel of the gun.
Abstract:
A piezoelectric fuze, especially for projectiles, having a piezoelectric element which converts the mechanical shockwave produced upon impact on a target into an output signal for igniting a detonator. A control circuit is provided for generating an output signal and a threshold switching circuit is provided for receiving the outputs of the control circuit and the piezoelectric element as a superimposed signal for establishing a connection between a power source and a detonator of the fuze when the threshold value of the threshold circuit is exceeded.
Abstract:
A pyromechanical disconnecting device that includes a housing having a receiving space for an ignition element and a supporting floor. A disconnecting tool is disposed in the housing and movable along a path toward a disconnecting point of a current conductor rail. Also disposed in the housing is an ignition element adapted to propel the disconnecting tool along the path to sever the current conductor rail. The ignition element includes an end having a conical flank facing the supporting floor of the housing. An elastic sealing element is arranged about the conical flank and the supporting floor to act as an axial tolerance compensator between the ignition element and the supporting floor of the housing.
Abstract:
A pyromechanical battery pole disconnect element, includes a housing (1) in which an electrical conductor is located, a pyrotechnic active element (14) including a breaking piston with a disconnect element (7) to sever the electrical conductor at an isolating point (11), and a pyrotechnic charge to drive the disconnect element (7). All of the current-conducting components except the active element (14) are combined to form a one-piece battery terminal clamp element (5).
Abstract:
The invention relates to a method for producing a cartridge consisting of a case and a projectile, characterized in that, once the cartridge is fully manufactured, a capillary active, acrylate-based adhesive sealing agent is applied in a controlled manner to the gap arising in the inner mouth of the case when the projectile is inserted therein, in a sufficient quantity as to guarantee full sealing of said gap.
Abstract:
A gas generator, particularly for an airbag, is characterized in that the gas-producing material (6) is arranged in a hermetically sealed charge container (9) and that a flame guide tube (10) is arranged in the charge container (9), which flame guide tube is formed in one piece with the charge container (9) and has only one flame outlet aperture (11).
Abstract:
A method for unlocking a window pane secured by a fastening element to a frame element of a window frame, with an inflatable pressure tube being located between the window pane and the frame element, said tube, upon being inflated, forcing the window pane out of the frame element. For reliable and improved element unlocking of the window pane, the pressure tube is inflated by actuation of at least one pyrotechnic gas generator connected to the pressure tube.
