Patent DE-4102272-A1 (DE)
Inventor: ALLERDING VOLKER
IPC: B64C1/14
Filed: 1991-01-26
Abstract: The invention relates to a device for locking and unlocking a panel (1) in the floor of a commercial aircraft. A bearing block (4) with an angled lever (5) articulated thereon is arranged on the panel (1) which can pivot into the passenger compartment. One lever arm (6) of the angled lever (5) is constructed as a handle while the second lever arm has a roller (8) on its end. When the panel (1) is in the closed position, this roller (8) engages in a pretensioned locking element (9) surrounding the roller, and when the panel (1) is opened, the roller (8) can roll off on a supporting edge (14) once it has overcome the pretensioning of the lock (9).

Patent DE-4102663-A1 (DE)
Inventor: BAUR FRITZ
IPC: F02M3/06
Filed: 1991-01-30
Abstract: The invention concerns a device for processing the surfaces of pipes, for instance for winding them with anti-corrosion tape, the device having a tool carrier, fitted with rollers, which can be placed against the pipe surface. The angle which the axes of rotation of the rollers make with the axis of the pipe can be adjusted to give the desired contact length. The tool carrier (2) is designed so that its rollers (3, 4) grip the pipe like a claw, at least one guide roller (10, 11) for a continuous drive belt (15) being mounted on the tool carrier (2) near the end of each claw arm, the drive belt passing round the side of the pipe (1) remote from the tool carrier (2). One of the rollers (10) is designed as a drive roller and is linked to a drive motor (12). The other roller (11) is designed as a brake roller and is linked to a preferably adjustable brake (14). The drive roller (10) and the brake roller (11) are mounted so that they can be staggered with respect to each other relative to the diametrical plane of the pipe. This enables large pipes to be wound using a small tool carrier, since it is merely necessary to fit a suitably long drive belt.

Title: Air mounted shaft for optical components - has two separate parts for radial and axial bearing
Inventor: LANGENBECK PETER DR ING
IPC: F16C32/06
Filed: 1991-03-18
Abstract: The separate shaft (4) and disc (1) are connected together and aligned relative to each other by a loose centring seat containing a centring ball (6). The force acting on the seat arises from the pneumatic piston between the shaft and the sleeve body. The disc is only mounted on air on one side. The sleeve (5) is closed at one end by a cap (7) so that an excess air pressure can be set in the resulting cavity whereby the longitudinal displaceable shaft (4) presses the disc (1) against the bearing disc (2) with air bearing by means of the centring ball (6). USE - To avoid faults in assembly for high-precision instruments.

Patent DE-4138043-A1 (DE)
Inventor: PHILIPP WILFRIED
IPC: B41F17/00
Filed: 1991-11-19
Abstract: The invention concerns a device for inking printing blocks (1), the inking device having a container (3), open on at least one side, which acts as a reservoir for the printing ink. The container rim on the open side lies against the printing block (1), and the container (3) and block (1) execute movements relative to each other. The invention ensures that a tighter seal is produced between the container (3) and the surface (4) of the block by virtue of the fact that only a first part of the rim of the container, which acts as a bearing surface (21), lies against the surface (4) of the block, while the other, second, part of the rim is a certain distance from the surface (4). A seal (10, 11) designed to prevent the ink from running away is associated with this part of the rim.
