Patent DE-3305882-A1 (DE)
Title: Combat vehicle, especially battle tank
Inventor: SPRAFKE UWE ING GRAD
IPC: F41H5/26
Filed: 1983-02-19
Abstract: A combat vehicle, especially a battle tank, having an entry and exit hatch arranged on the top side of the vehicle body or of the turret and closable by means of a cover. The hatch cover is constructed from two cover parts of differing mass movable relative to one another. An upper cover part (1) is arranged above the hatch aperture (6) and is displaceable parallel to the closing plane of the hatch. In a first embodiment, a lower cover part (2) movable perpendicularly to the closing plane is arranged on the underside of the upper cover part (1). For closing, the upper cover part (1) is pushed over the hatch aperture, and then the lower cover part (2) is lowered until the hatch is sealingly closed. In a second embodiment, the upper and lower cover parts are separated. The lower cover part is designed as a cylindrical ring and is arranged within the hatch aperture so as to be movable perpendicularly to the closing plane. For closing, the upper cover part is pushed over the hatch aperture, and then the lower cover part is raised until the upper edge of the cylindrical ring bears sealingly against the underside of the upper cover part. <IMAGE>

Title: Method for hydromechanical deep drawing and arrangement for carrying out this method
Inventor: TOMASEK JIRI DIPL ING
IPC: B21D22/28
Filed: 1983-02-21
Abstract: The method for hydromechanical deep drawing is carried out in a pressure chamber by means of telescopic drawing punches interacting in different ways. The sheet-metal blank is first of all drawn into the pressure chamber by simple drawing using telescopic drawing punches until the bottom of the semi-finished drawn article seals off the fluid charge in the bottom part of the pressure chamber, whereupon the bottom of the semi-finished product is acted upon using only the internal drawing punch in interaction with the fluid charge until the drawn article is drawn out to the final shape from the semi-finished product obtained by simple drawing, the final shape corresponding to the shape of the internal drawing punch.
Patent DE-3306239-A1 (DE)
Title: System of sliding elements
Inventor: LOEHNERT JOCHEN DIPL ING
IPC: E05D15/58
Filed: 1983-02-23
Abstract: System of sliding elements, such as doors for furniture and building, etc., in which the individual elements lie in a single plane in the closed state and are guided past one another by rolling on running tracks which can be shifted transversely to the front by parallel displacement, rolling bodies, tilting, rolling or rotation about a longitudinal axis. Normally, two running tracks move simultaneously towards and away from one another during opening and closing respectively. The force transmission between the two profiles takes place by means of, among other things, attached gearwheel segments. The running-track feet are designed as rolling surfaces. Their radius is smaller than the running-track height, so that during parallel displacement a dead centre and in the two end positions a stable equilibrium are obtained. The dead centre can be so adjusted by means of the difference between the running-track height and rolling-surface radius that even heavy doors can be actuated with normal effort. <IMAGE>

Title: Method and apparatus for separating tobacco leaves
Inventor: SPRY ROGER BOLT
IPC: A24B3/06
Filed: 1983-12-01
Abstract: The method for separating the laminates of a mass of tobacco comprises features whereby the mass is laid on a conveyor with projections located thereon, the mass is held, the leaves or laminates are drawn off from the underside of the mass, and a pressure is applied to the mass on the upper side thereof and becomes greater as the laminates are drawn off. An apparatus which is suitable for separating laminates of a tobacco mass has a conveyor which has projections located thereon, and also a device which holds the mass on the conveyor, during which the conveyor draws off laminates from the underside of the mass, and a device which exerts a pressure on the mass on the upper side thereof, which pressure becomes greater as the laminates are drawn off. In this manner, it is possible to effect the separation of an entire layer of compressed tobacco leaves, the leaf strips being drawn off in a direction parallel to the planes of the leaves.
