Title: Emergency-off linkage, using the master-slave principle, for machine controllers
Inventor: OEHRING WERNER DIPL ING
IPC: G07C3/00
Filed: 1984-12-04
Abstract: For safety reasons, a so-called "emergency-off loop" is specified for machines which are used for machining and processing workpieces (manufacturing machines). In the event of an emergency, this loop makes it possible quickly to stop the machine operating, irrespective of the location of the person who notices the danger to personnel or the machine. According to the invention, when a plurality of machines are coupled in terms of the emergency-off facility, a master/safety-protection combination is provided which monitors all the emergency-off loops in each master and slave. <IMAGE>

Title: Method for inserting one tube end into another and connecting the said ends
Inventor: RAUSCHNABEL EBERHARD DIPL ING
IPC: B21D39/04
Filed: 1985-03-08
Abstract: The invention proposes a method for inserting one tube end (3 or 25) into another (4 or 22) with a clearance or interference fit and connecting them together. In this method, the two tube ends (3, 4 or 22, 25) are first of all positioned in alignment with one another and the inner tube end (3 or 25) is then subjected to stamping with a reduction in diameter which permits insertion into the outer tube end (4 or 22) and centric fixing on a stamping head (5 or 27) situated in the interior of the tube. After the tube ends (3, 4 or 22, 25) have been inserted one into the other, the inner tube end (3 or 25) is expanded by pulling the stamping head (5 or 27) out of the inner and outer tube ends (3 or 25 and 4 or 22), thereby establishing a frictional or positive connection between the two tube ends (3, 4 or 22, 25). <IMAGE>

Title: Device for conditioning and monitoring signals of a distance measuring system
Inventor: MACHAC VLADIMIR DIPL ING
IPC: G01D1/02
Filed: 1985-08-29
Abstract: The invention relates to a device for conditioning and monitoring individual measurement signals (7) of a distance measuring system. It is provided that a memory (2) has memory locations for groups (71, 72, 73) consisting of a defined number of measurement signals. The memory (2) is connected to an evaluation unit (3) in which the largest and the smallest individual measurement signal (711, 712) of a group (71) is selected from the memory (2) and the mean value of the other measurement signals (713 to 716) located in the memory (2) is determined as a representative measurement signal (81). The evaluation unit (3) is connected to a monitoring unit (4) which is also connected to the memory (2). A signal is emitted at the output of the monitoring unit (4) if one or more individual measurement signals (7) of a group (71, 72, 73) in the memory (2) deviates from the representative measurement signal (81, 82, 83) by more than an adjustable limiting value (9). The outputs of the monitoring unit (4) and of the evaluation unit (3) are connected to a control and instrumentation technology device (10) which accepts a representative measurement signal (8) only if there is no signal at the output (43) of the monitoring unit (4). <IMAGE>

Title: Arrangement for controlling the discharge control element of a compacting machine
Inventor: RASSEK ANDREAS
IPC: B03B5/24
Filed: 1985-11-06
Abstract: The position sensor, which samples the float movements, is a rotation-angle sensor (9) which introduces an electrical analog signal (which is proportional to the float position) as an actual value into the control loop (10, 11, 16, 17, 18, 20) which controls the discharge control element (2). Provided in the control loop is a controller (11) having a setting-range sensor, which contains two limit-value switches (14o, 14u) which define range limits. The controller produces an electrical signal, as a control deviation to adjust the actuating drive (18) and the discharge control element (2) as a function of the actual value exceeding or undershooting the range. The housing of the rotation-angle sensor (9) is supported such that it can rotate; its rotation position tracks the position of the discharge control element (2), via feedback (19), in order to cause a shift in the zero point of the electrical analog signal as a function of a position change of the discharge control element. <IMAGE>

Title: Time indicator in the form of a parking disc
Inventor: GOETZ HANS-JOACHIM
IPC: G07C1/30
Filed: 1986-06-05
Abstract: The time indicator exhibits a digital liquid-crystal display (2), a battery operated timing circuit (1) with a clock generator (10), a counting arrangement (14), a memory circuit (15) for storing all counts, and a driver circuit which activates the liquid crystal display in accordance with the memory contents, furthermore a motion detector (3) and a switching device (4) arranged between the detector and the memory circuit.

In the excitation state of the motion detector (3), in contrast, the memory circuit is coupled to the counting arrangement so that the real time is continuously transmitted via the driver circuit to the time display (2). All electrical components are moulded into a housing which transmits the vibrations of the vehicle to the integrated motion detector (3). <IMAGE>
