Patent number: 4838167Abstract: A method suitable for protecting targets against attacking projectiles as rockets consist in producing an infrared jamming radiator which radiator jams the infrared target finder of the attacking projectile. The jamming radiator is produced in the vicinity of the target and may be embodied by a jammer cloud consisting of burning particles, preferably foil strips, emitting an infrared radiation more intensive than the infrared radiation of the target and staying sufficiently long in the air as to divert the rocket from the target. The strips are stowed in a container which is emitted from the target and distributes the ignited strips into the airspace near the target.Type: GrantFiled: June 16, 1978Date of Patent: June 13, 1989Assignee: Firma Buck KGInventors: Georg Prahauser, Paul Huber, deceased, Alois Schiessl, legal representative

Patent number: 4624186Abstract: An infrared radiation-emitting projectile includes a casing and a contact head attached thereto, the casing containing an igniter-destructor capsule centrally positioned therein which contains an igniter-destructor charge, a layer of combustible flakes between the igniter-destructor capsule and the side wall of the casing, and an ignition-expediting material such as red phosphorus between the igniter-destructor capsule and the side wall of the casing.Type: GrantFiled: April 23, 1986Date of Patent: November 25, 1986Assignee: Buck Chemisch-Technische Werke GmbH & Co.Inventors: Axel Widera, Alois Schiessl, Walter Hanser, Peter Rayer, Klaus Hieke
-
Patent number: 4435233Abstract: This invention comprises a process for the preparation of a smoke composition based on hexachloroethane, zinc oxide, and metal powder, in which zinc oxide granules obtained by high compression and subsequent crushing are used as a mixture component and the intermittent burnoff of previous smoke compositions of this type is thus avoided; the invention also concerns a smoke generator filled with such a smoke composition.Type: GrantFiled: January 29, 1982Date of Patent: March 6, 1984Assignee: Buck Chemisch-Technische Werke GmbH & Co.Inventors: Peter Rayer, Hartmut Krone, Alois Schiessl, Wolfgang Steinicke, Wolfgang Trede

Patent number: 4370929Abstract: A contact head for a projectile which is capable of being fired from an electrically actuable launcher comprises a solid metal core formed on one side with a recess for constituting a propellent charge chamber in which are located a propellent charge and a primer capsule. The recess is closed by a base plate having breakage points for the egress of gases generated by ignition of the charge. The part of the core surrounding the recess is formed with first and second sets of bores spaced equiangularly about the axis of the core for receiving connecting screws for connecting the, contact head to a projectile and for receiving fixing screws for fixing the base plate to the core, respectively. An elastic protective member coaxially surrounds the head and is preferably subdivided into three rings, e.g. of rubber, which carry two metallic contact rings connected to the primer capsule by firing circuit wires.Type: GrantFiled: August 4, 1980Date of Patent: February 1, 1983Inventors: Wolfgang Steinicke, Wolfgang Badura, Alois Schiessl, Werner Weinzierl, Hartmut Krone

Patent number: 4173931Abstract: An incendiary warhead comprises a destructible body carrying a plurality of stacked incendiaries. Each incendiary comprises a housing containing a compressed three-part icendiary filling. The filling comprises a flame substance for forming an intense flame, a thermit unit for forming a red-hot slag, and a combustion transfer substance which projects into both the flame substance and the thermit substance to be ignited by the former and ignite the latter. A tail unit is mounted at a top end of the housing to control the rate of descent of the incendiary. The tail comprises a hook, a pair of chains connected to the hook, and a vane connected to the free end of each chain. An anchor point extends from a bottom end of the housing and is in the shape of an arrowhead having barbed side edges.Type: GrantFiled: February 21, 1978Date of Patent: November 13, 1979Assignee: Firma BUCK Chemisch-Technische Werke GmbH. & Co.Inventors: Alois Schiessl, Georg Praehauser, Wolfgang Badura, Wolfgang Trede

Patent number: 4015355Abstract: An incendiary projectile carries an incendiary charge and a control charge arrangement for igniting and disintegrating the incendiary charge. The control charge arrangement is ignited by the propellant charge which launches the projectile and then immediately ignites the incendiary charge and finally causes disintegration of the projectile. In one embodiment the control charge comprises a first charge, including a glow and delay composition, and a disintegrating charge which is ignited by the first charge. In another embodiment the control charge comprises a glow and delay composition which ignites and then heats the incendiary charge to produce disintegration of the projectile. A novel tubular housing for the control charge is provided to prevent premature disintegration and minimize atomation of the incendiary charge.Type: GrantFiled: March 14, 1975Date of Patent: April 5, 1977Assignee: Firma Buck K.G.Inventors: Alois Schiessl, Hartmut Krone

Patent number: 3979850Abstract: There is disclosed a handgun intended for one-time use for launching a projectile. The gun is stored in a condition wherein a handle of the gun is folded to cover the trigger. A releasable locking member locks the handle in its folded position. In its folded position, the handle biases a pair of knobs inwardly to prevent actuation of the trigger, while a portion of the trigger engages the firing pin to prevent movement of the firing pin. In the stored condition of the handgun, the firing pin is uncocked and is unable to be moved into a cocked position. The locking member has a guide portion which is slidable within a bore containing the firing pin and its biasing spring. The guide portion acts as an abutment and a guide for the rear end of the spring. In one embodiment of the invention, the locking member is cammed inwardly by the handle as the handle is unfolded, to automatically cock the firing pin spring.Type: GrantFiled: April 30, 1975Date of Patent: September 14, 1976Assignee: Firma Buck K.G.Inventors: Alois Schiessl, Rudiger Van Acken
