摘要： The present invention relates to an electric igniter of the type comprising two electrically conductive bodies separated by an insulating body. The conductive bodies and said insulating body define a very smooth common surface having a thin connective member electrically connecting the conductive bodies. A pyrotechnic charge is in contact with said thin connective member for ignition when said member is heated by a flow of electric current therethrough. The connective member comprises one or more thin metal layers which are bonded to said smooth surface. In order to give the igniter a somewhat "slower" electrical response as well as increasing the mechanical strength of the connective member. The connective member also comprises an additional thin layer of inert material, preferably a glass- or SiO2-layer, applied directly on the upper metal layer.

摘要： An electric igniter is disclosed which comprises two elements made of electrically conducting material, a body separating the elements and made of electrically insulating material, such as glass or material containing glass, at least one further electrically conducting element arranged on a surface common to the two elements and the body for connecting the two elements electrically, and also a pyrotechnical composition in contact with the surface and the further element. Burning of the composition can be initiated by means of heat developed in the further, initiating element.

摘要： An improved safety device for a projectile includes a movable element which selectively positions a priming cap in position to ignite the charge of the projectile. A safety plate separating the priming cap and the main charge of the projectile is pierced by a member projected from the safety device by the gas pressure of the ignited priming cap.

摘要： A tank having a firearm mounted thereon for selective elevation and depression about trunnions located within a turret, is provided with a cover pivotally mounted on said turret and adapted to be engaged by the recoil jacket of the gun when the gun barrel is in a depressed position to swing the cover upwardly thereby to cause the recoil space to extend at least partially above a frame for the cover. The arrangement further includes a cartridge case deflector located within the tank below the cover and pivotally fastened at its opposing ends to a portion of the cover and to the recoil jacket of the barrel respectively, and the sides of the cartridge case deflector are adapted to be compressed by one another when engaged by a loading tray within the turret to enable rounds to be moved from a magazine to a loading position.

摘要： In order to increase the measurement accuracy in the case of determining the offset of an object from a reference line which is defined by an optical measuring device, a rotatable shutter (12) is arranged in the imaging plane of the objective (11) of said measuring device. The shutter (12) has an opening (21) which is bounded on one side by a straight line and by a logarithmic spiral on the other side. The radiation pulses which strike a photosensor (15) during rotation of this shutter have a different length, depending on the distance of the image in the imaging plane from the centre, and have a different phase angle with respect to the shutter rotation, depending on the angular position of said image. The position coordinates of the imaged target object with respect to the reference line can be determined by means of evaluation electronics (17) in this manner, the measurement accuracy being linear with respect to the distance of the image from the centre of the shutter, that is to say being small close to the centre.

摘要： An improved tool for railway track adjustment machines is disclosed which may be made by processes forging, casting, and which includes a shaft and a blade manufactured as separate entities and force-fitted together. In making the tool the lower end of the shaft is formed so that it is able to be forced between flanges located on the rear side of the blade. This lower end preferably has a transverse cross section shaped as a trapezoid with an apex angle gamma and is upwardly and outwardly tapered at an angle alpha . The flanges located on the rear side of the blade are manufactured from the same piece of material as the blade and define a slot which opens upwardly and outwardly at an angle to the direction of the longitudinal axis of the tool and the symmetrical plane of the blade. A method the slot defined between the flanges has a transverse cross section which tapers inwardly at an angle delta and may be formed by deforming the blade.
