Patent DE-3313291-A1 (DE)
Title: Mechanical seal
Inventor: FALK ARMIN DIPL ING
IPC: F16J15/34
Filed: 1983-04-13
Abstract: The invention relates to a mechanical seal which comprises a fixed sliding ring (1) and a rotating sliding ring (2). Between the sliding rings (1 and 2) there is a radially running oil-lubricated sealing gap (6). At least one of the sliding rings (1 and/or 2) is composed of a dimensionally stable basic body of high thermal conductivity (for example metal) which is covered at least in the region of the sealing gap (6) by a thin layer (7) of a plastic (for example PTFE). By virtue of the layer of plastic (7), a low friction coefficient is achieved even in the region of mixed friction, so that the development of heat is low. The heat produced is dissipated well on account of the small thickness of the layer of plastic (7). <IMAGE>

Patent DE-3319495-A1 (DE)
Title: Clamping device for a reflected-light specimen cylinder in microscopy
Inventor: KIELMANN JUERGEN DR MED
IPC: G02B21/26
Filed: 1983-05-28
Abstract: The invention relates to a clamping device which speeds up and simplifies the plane-parallel alignment of polished-section testing cylinders in reflected-light microscopy. In this case, the specimen can be positioned under traditional microscope stands without further aids such as plasticine and section presses. The orientation on the test surface is performed using the conventional device (mechanical stage) and "visible" beam guidance, so that apart from the accustomed manipulation there is no need to undertake conversion with supplementary parts. The plane of the polished section can be individually inclined using integrated levelling screws. Three-dimensional illumination by means of eccentric beam guidance is possible in the sense of "oblique illumination", so that this representation is also permitted by microscope objective heads without central beam variation. This effect can also be used for three-dimensional surveys on stereomagnifiers with a coaxial illuminating system.
Patent DE-3323995-A1 (DE)
Title: Compressed diaphragm spring clutch with automatic wear compensation in the area of the tilting circle
Inventor: PIEPER NORBERT
IPC: F16D13/75
Filed: 1983-07-02
Abstract: The invention relates to the automatic play adjustment on the clamping point of a diaphragm spring in the clutch housing. The play is adjusted by means of compensating elements, actuatable by centrifugal force and displaceable essentially radially, which in the event of radial displacement due to reciprocal inclination of the bearing surfaces, on which the compensating elements bear, perform an axial compensating movement and are held by virtue of self-locking against any displacement radially inwards. The radial displacement occurs automatically due to the centrifugal force whilst the friction clutch is in the engaged condition, since in this case that clamping side of the diaphragm spring provided with these compensating elements is load-free.

Title: Method and device for operating a high-voltage direct-current transmission system
Inventor: NEUPAUER HELMUT DR
IPC: H02M7/757
Filed: 1983-11-09
Abstract: The output on the AC voltage side of a high-voltage direct-current remote transition or back-to-back linking device contains an invertor whose control angle ss* is determined by a reference variable controller and whose valves are intended to be turned off at a specific phase angle (desired turn-off angle  gamma *). However, the normal angular controls on the invertor side have a relatively large amount of inertia and, for stable high-voltage direct-current transmission operation, correspondingly slow current control should thus also be provided on the rectifying input side of the path, the control of the two converter stations being coupled to one another via telecontrol signals. According to the invention, the control angle formed by one of the reference variable controllers is highly accelerated for the invertor on the output side by using advanced control for the turn-off angle, so that correspondingly fast current control can also be used on the rectifier side. In this case, no telecontrol lines are required. The advance control angle on the invertor side is calculated from the desired turn-off angle and the inductive DC voltage drop of the invertor. <IMAGE>
Patent DE-3343883-A1 (DE)
Title: Method and device for two-point control of a load current
Inventor: MISAIZU AKIRA DIPL ING
IPC: H02P7/29
Filed: 1983-12-05
Abstract: Between a connection of the load (5A) and a direct-voltage source (1), switching elements (2A, 2B) are arranged, by means of the alternating actuation of which either the direct voltage is connected to the load or a free-wheeling path for the load current is closed. The switching elements are actuated by the output signal of a comparator (7A) with hysteresis, to which the setpoint/actual-value difference of the load current is connected. The tolerance limits, on the attainment of which the comparator actuates the switching elements, are periodically changed by inputting a periodic clock signal generated in a signal generator (9A), as a result of which the switching cycle of the switching elements is synchronised to the clock signal. During the switching, this results in a constant-frequency noise and, in addition, a simple and relatively constant control is achieved. <IMAGE>
