摘要： A method and a device for the purpose of de-icing those covers and other surfaces of limited size which can be subjected to severe icing and which it may be necessary to make ice-free at very short notice. Examples of the types of surfaces intended are protective doors for ship-borne missiles and torpedo tubes, emergency exit doors, and helicopter landing platforms etc. These surfaces are de-iced by an interior igniting primed tubular power charge which in the case of doors is placed directly in a groove along edges which the door seals against the surrounding door frame or another mating door, and in the case of other types of surfaces is placed in accordance with a pattern intended for that particular surface. The tubular powder charge is placed in an open groove in the relevant surface which faces in the same direction as it is desired that the ice should be flaked loose.

摘要： Apparatus for supporting and elevating a gun barrel, wherein a pair of telescoping cyclinders are attached to the barrel and frame of the gun, respectively. A piston assembly positioned between the cylinders supports the unbalanced weight of the barrel against a fluid medium with a control valve varying the resulting pressure ratio during elevation of the barrel.

摘要： A rammer head assembly for moving a projectile and a propellant charge from a first position behind a barrel chamber of a firearm into a second position within the barrel chamber, with the propellant charge being positioned adjacent to a closed rear end of the chamber. The rammer head assembly being rotatably supported so as to swing the propellant charge end-to-end behind the projectile and including a pivotable front end portion for contacting and moving the projectile into the firing chamber.

摘要： A method of producing pressed rocket propellant with good flash suppression and a high burning velocity, i.e. containing optimal quantities of flash reducing agent and catalysts. The meethod is characterized by the entire quantity of flash reducing agent required in order to achieve the result desired being mixed into a separate quantity of propellant while the entire quantity of catalysts required in order to achieve the result desired is mixed into the remaining quantity of propellant, after which these propellants containing either flash reducing agent or catalysts are converted into an appropriate form and mixed in layers or in its entirety and thereafter pressed into the form desired. In the body of propellant obtained, the flash reducing agent and catalysts will be separated, and will not interfere with each other's function.

摘要： A projectile such as a bomb or rocket is provided with a flare section comprising an elongated cylindrical casing containing a body of flare material. An elongated support element extends through the flare body along its central axis, and a truncated conical flame spreader is attached to one end of the support element with the smaller end of the truncated cone in firm engagement with an end surface of the flare body and with at least the major portion of the conical surface of the flame spreader recessed within an extended portion of the casing. A nose fairing is removably attached to the extended portion of the casing and is adapted to be blown away from the casing by a charge located in a cavity within the flame spreader. The charge is ignited by a fuse which extends through the hollow center of the support element, and when ignited the charge also operates to ignite the end surface of the flare body surrounding the flame spreader to cause a flame to be emitted outward from the opened end of the casing in the region between the extended portion thereof and the conical outer surface of the flame spreader acting as a flame deflection surface.

摘要： Proyectil perforante, que comprende una carga hueca y un elemento de contacto de impacto situado en la ojiva del proyectil y dispuesto para proporcionar contacto eléctrico para la iniciación de la carga hueca al establecer impacto del proyectil contra el blanco, caracterizado porque la ójiva del proyectil tiene una punta reforzada (11), para penetración mecánica del blindaje activo (2) y porque el elemento de contacto de impacto (12) queda posicionado de manera tal en la ójiva que se obtiene contacto solamente cuando la punta reforzada (11) ha penetrado en el blindaje activo (2) sin detonación.
