Abstract:
A blank cartridge for training purposes in the form of an elongated case made of thermoplastic synthetic resin and forming a hollow simulated projectile and a powder chamber. The case is provided with weakening lines for providing a predetermined rupturing of the case in the form of external longitudinal grooves or slots extending from the tip of the simulated projectile over substantially the entire length of the projectile. The powder chamber is provided with a powder charge mass of at least 10 g. and internal longitudinal grooves may also be provided.
Abstract:
An electronic sensing system for triggering the activation of a safety mechanism of a vehicle during a vehicle collision. The system includes a piezoelectric transducer providing an output indicative of shock acceleration of the vehicle, an evaluating and safety circuit for processing the output of the transducer in accordance with predetermined dynamic deformation characteristics of the vehicle and for providing a triggering output signal to an ignition circuit for activating the safety mechanism such as an air bag system. The evaluating and safety circuit provides a triggering output signal depending upon whether at least one of a predetermined threshold value has been attained by the output signal of the transducer and that the value is maintained for a predetermined delay period.
Abstract:
A control element to be electrically ignited for pin retraction, wherein the pin is guided in a housing in which the electrical primer element is accommodated and is optionally provided with a delay device. In the starting position, a compression spring presses the pin with an integrally attached piston against the primer element. The piston rests on a supporting element of the primer element. After ignition of the primer element, the compression spring presses the pin with a residual force against the remaining portion of the supporting element which has been penetrated.
Abstract:
A magazine for caseless propellant charges which are entirely consumed leaving no residue after burning, for use in both military and commercial applications, including an extended flexible band having a plurality of recesses, each adapted for receiving a single propellant charge, spaced along the length of said band. Additionally, the band may incorporate a plurality of depressions, apertures and/or projections spaced along the length thereof for indexing of the magazine relative to the activating device. Further, a readily detachable foil may be secured adhesively along one or both major surfaces of the band to retain the propellant charges with the respective recesses and simultaneously shield them from heat which could cause accidental detonation.
Abstract:
An irritant agent device including an irritant agent element formed by an irritant agent cartridge such as a tear gas cartridge surrounded by a soft, resilient casing for protecting against physical injuries or mechanical damage at a target site and having a launching tube connected with element for facilitating the launching of the element from a barrel of a firearm. The launching tube is positioned within the casing and may be completely hidden within the casing such that no portion of the tube protrudes therefrom or may extend outwardly from the casing and be separable from the element after launching. The launching tube is also provided with a braking arrangement mounted thereon for aiding in the separation of the tube from the element after launching.
