Patent number: 6183247Abstract: A heating device for burning fuel pellets (2) having a spherical combustion area (7), the surrounding wall of which is perforated (37), is disclosed. The combustion area (7) is surrounded concentrically by a wall(40) having perforations (36) and is spaced from the wall (10) of the combustion chamber. The space between the two walls (10 and 40) is utilized to hold the fuel pellets which are ignited by a heated medium directed from the outside towards both the walls (10 and 40).Type: GrantFiled: November 12, 1999Date of Patent: February 6, 2001Assignee: SL VarmeekonomiInventor: Sven Lindberg

Patent number: 5115715Abstract: A breech mechanism for large caliber artillery pieces is characterized by a specifically designed sealing function in the form of an intermediate layer between a main portion of the breech mechanism and a seating portion displaceable in relation thereto by the gas pressure in the gun. The seating portion, on being displaced towards the breech, compresses the intermediate layer disposed therebetween and consisting of an elastically deformable refractory material which, on its deformation, is urged into tight abutment against the rear portion of the gun barrel about the loading space of the gun along a gap between the seating portion and the main portion of the breech mechanism.Type: GrantFiled: May 30, 1990Date of Patent: May 26, 1992Assignee: Aktiebolaget BoforsInventors: Sven Lindberg, Kjell Eriksson

Patent number: 5020415Abstract: A tank with an overlying gun which is mounted in a cradle disposed on the crew turret also includes a loading pendulum which is disposed on a journal ring and pivotal in relation to the crew turret. The loading pendulum and the gun are asymmetrically journalled, such that the positions of the gun and the loading pendulum are dependent upon the elevation/depression of the gun. The gun is longitudinally/vertically displaced in the plane of elevation on elevation/depression. This is achieved in that the cradle is retractably disposed in the plane of elevation with the aid of a member determining the degree of retraction of the gun and may be elevated/depressed about an abutment pivotally mounted between the revolving portion, or turret, and the gun. The abutment is movable in the plane of elevation. The abutment and the cradle are adapted in the different elevations/depressions, to adjust the position of the breech of the gun to the pivotal movement of the loading pendulum about its pivotal center.Type: GrantFiled: October 12, 1989Date of Patent: June 4, 1991Assignee: Aktiebolaget BoforsInventor: Sven Lindberg

Patent number: 4991489Abstract: A loading device for large-caliber weapons allows for firing with rounds consisting of different types of projectiles and charges/cartridges of different sizes which are combinable with the projectiles upon being loaded into the weapon. The projectiles are placed in a first magazine at which a first transfer device is disposed. This first transfer device transfers each respective projectile to the axis of the bore of the weapon so as to make possible the interaction of the projectile with a ramming device which rams home each respective projectile placed in the axis of the bore. The charges/cartridges are placed in a second magazine at which second transfer devices are disposed, for transferring each respective charge/cartridge to a defined position behind the associated projectile rammed home by the ramming device.Type: GrantFiled: September 20, 1989Date of Patent: February 12, 1991Assignee: Aktiebolaget BoforsInventor: Sven Lindberg

Patent number: 4989494Abstract: A tank (1) is designed with an overlying gun (3) and a crew turret (2). The traverse movements of the gun and the crew turret are coordinated. A complete ammunition handling system (9, 11) for reserve ammunition (10) is provided ancillary to the standard feeding and loading system. The reserve system includes an ammunition tube which is guided by a linkage system (9) between a rest position and a position in an extension of the bore axis (5). The ammunition tube is provided with its own ramming means (11a). At a predetermined traverse position for the gun and the crew turret, reserve ammunition may be transferred to the system when this assumes an initial position. The reserve system may be actuated in a per se known manner so that the ammunition tube assumes a position in association with the breech, where the ammunition unit may be longitudinally displaced into the gun with the aid of the above-mentioned ramming means (11a).Type: GrantFiled: October 12, 1989Date of Patent: February 5, 1991Assignee: Aktiebolaget BoforsInventor: Sven Lindberg

Patent number: 4961367Abstract: A tank features magazines which hold ammunition units (3a, 3b) of different types. The feeding path includes discharge devices for discharging the ammunition units from the magazines, and a turntable (8) for receiving each respective ammunition unit discharged from the magazines and turning the ammunition unit to a traverse direction which coincides with a preset traverse direction for the gun of the tank. There are further included means for transferring each respective ammunition unit from the turntable to the ramming position in the gun. The turntable is provided with two carrier units (8a, 8b) for ammunition units. The carrier units are alternatingly movable into and out of the feeding path for the ammunition units. On feeding of the first type of ammunition unit (3a), the first unit operates in the feeding path, while the second unit is located outside the feeding path where it carries an ammunition unit (3b) of the second type.Type: GrantFiled: October 12, 1989Date of Patent: October 9, 1990Assignee: Aktiebolaget BoforsInventor: Sven Lindberg
