Title: Cutting-off apparatus for cutting off a tubular workpiece
Inventor: FRIEDRICH EMIL HEINRICH
IPC: B23D21/00
Filed: 1981-05-20
Abstract: The invention relates to a cutting-off apparatus with a clamping device (5) for holding the workpiece (8) in the cutting position relative to an entering means (1) for starting the cut on the workpiece (8) at the point of the subsequent cutting action of the cutting-off blade (2), in the course of which the entering means (1) and the cutting-off blade (2) for severing the workpiece (8) following the entering cut, which workpiece (8) is secured in the clamping device (5), can be moved in a predetermined cutting plane (81) relative to the clamping device (5). In order to eliminate in particular a collision between entering means (1) and cutting-off blade (2) in a constructively simple manner, it is proposed that the entering means (1) and the cutting-off blade (2), orientated in the cutting plane (81), be arranged on a tool holder (3) at a distance from one another. The tool holder (3) can be moved in a reciprocating manner at a distance from and relative to the clamping device (5) between two end positions transversely to the centre axis (50) of the clamping device (5) or transversely to the longitudinal axis (80) of the workpiece (8) secured in the clamping device (5). In one end position of the tool holder (3), the entering means (1) is located relative to the clamping device (5) in an initial position for the entering action and can be moved into the other end position with the tool holder (3) while starting the cut in the workpiece (8) and can be moved back into the first end position after the severing operation. In the other end position of the tool holder (3), the cutting-off blade (2) is located relative to the clamping device (5) in an initial position for the severing operation and can be moved in a reciprocating manner transversely to the direction of movement of the tool holder (3) for severing the workpiece (8) at the entering point and for the return motion. A reduction in the number of motional steps determining a cutting-off cycle and further effects important in particular for an overhung cutting-off device can be achieved by a further cutting-off blade (2'), with cutting edges (21') orientated in the cutting plane (81), being arranged on the tool holder (3) at a distance from the first cutting-off blade (2), which further cutting-off blade (2'), in one end position of the tool holder (3), is located in an initial position for a severing operation and which can be moved in a reciprocating manner transversely to the direction of movement of the tool holder (3) for severing the workpiece (8) at the entering point and for the return motion. The entering means (1) is preferably arranged centrally between the two cutting-off blades (2; 2'), is designed to have a cutting action on both sides and, in both the one and the other end position of the tool holder (3), is located relative to the clamping device (5) in an initial position for the entering operation.

Inventor: POLLOK HANS-JUERGEN DIPL ING
IPC: F16C37/00
Filed: 1981-10-13
Abstract: A self-pumping thrust bearing for electric machines having a vertical shaft is disclosed in which the oil is circulated via radially-extending bores which suck hot oil from an oil space adjacent to the vertical shaft and conduct it to at least one cooler through a stationary ring canal. In order to prevent air bubbles or foamed oil from being circulated with the oil, the oil suction space is enlarged by a recess extending to the radial bores on the inside of the thrust ring and additional radial bores are provided which open toward the oil suction space below the top end of a cylinder wall rotating with the thrust bearing which begins at the thrust ring. The oil contained in the oil suction space rotates together with the thrust ring, and a segregation of air bubbles or oil foam from the oil is obtained during the dwell time of the oil in the oil suction space.

Patent DE-3205224-A1 (DE)
Title: Magnetic door lock
Inventor: TRAPMAN JAN
IPC: E05C19/16
Filed: 1982-02-13
Abstract: A magnetic door lock is equipped with a normal lock bolt (5) which conventionally forms the locking device of the lock. The lock bolt (5), which projects with its front side (20) out of the lock plate (4) into the door frame only when the door leaf is in the closed position, is retained in the door frame by means of a permanent magnet (17). When the lock bolt (5) is displaced, together with the permanent magnet (17) fastened to it, into the lock plate (4) after the door has been opened, a flat head side of the door is obtained, and the lock bolt (5) is retained by a limiting member as a result of a magnetic effect with a somewhat low force of attraction, as long as the door does not return to the closed position. In the closed position of the door, the much lower force of attraction, to which the lock bolt (5) in the lock interior is subjected by the permanent magnet (17), is overcome completely by the very much higher permanent-magnet force effect of the permanent magnet (17) which positively brings about the locking of the door onto the opposite contact part (21) on or against the door frame. <IMAGE>

Title: Process for producing two-sided copies, and appliance for carrying out the process
Inventor: KNECHTEL WILHELM
IPC: G03G15/00
Filed: 1982-06-04
Abstract: In a process and appliance for producing two-sided copies, the copying paper is, after transfer of the powder image from one side of the original to the copying paper, deposited on a belt which subsequently reverses its direction of running in order to feed the copy to a transport mechanism which then moves the rear of the copying paper up to the transfer station of the process cylinder. The copying paper is then again fed to the belt which then runs forward and feeds the copying paper covered with a powder image on both sides to a fixing device. To produce colour copies, each side of the copying paper is moved in-between by means of the transport belt several times past the transfer station of the process cylinder, in order to collect the powder images of the individual colour separations on the copying paper. After this step, the belt feeds the copying paper covered on one side with the powder images of the individual colour separations to an intermediate fixing device and then to the transport mechanism which moves the rear of the copying paper up to the process cylinder. The belt again picks up the copying paper and runs repeatedly to and fro with swivelling away from the process cylinder in between, so that the powder images of the individual colour separations of the rear of the original are collected on the rear of the copying paper. The belt then feeds the copying paper to a final fixing device. <IMAGE>
