Patent DE-3605614-A1 (DE)
Inventor: ROEMMEN HANS
IPC: B21B31/28
Filed: 1986-02-21
Abstract: So that the chocks containing roll bearings can be guided in windows of stand housings with little frictional losses and if need be in such a way that they can be set horizontally, the chocks or the guide pieces guiding them are pivotably connected to guide links which are pivotable around pivot pins arranged on the housing beams. If the pivot pins guiding the guide links are designed as eccentric pins with adjusting devices allocated to them, horizontal settings can be made with little effort just as easily as re-adjustments of the guide clearance can be made, or else, for example, guide pieces can be retracted for carrying out the roll change. <IMAGE>
Patent DE-3609419-A1 (DE)
Title: Modulating device for friction clutches
Inventor: GAZYAKAN UENAL
IPC: F16D35/00
Filed: 1986-03-20
Abstract: In this modulating device for pressure-actuable friction clutches the matching of the rotational speeds of both shafts (2, 3) is ensured by means of a relatively small viscous coupling (7) which acts as an auxiliary clutch and receives and transmits the signals of the rotational speed differences. Differential torques for the adjustment of a flow (8, 9) of pressure medium to and from the clutch cylinder (5A), provided by an external source of pressure medium, are obtained from this viscous coupling by means of a control element (10). The actuating strokes of this control element (10) can be both redirected by means of an expanding device (6) and modulated in their functional dependence by means of a detent curve (16A) and a control cam (16) in such a way that, for example, suppression of response and gentle engagement of the friction clutches (4) are obtained. <IMAGE>
Patent DE-3615982-A1 (DE)
Title: Endless polarisation control
Inventor: NOE REINHOLD DIPL ING
IPC: G02F1/01
Filed: 1986-05-13
Abstract: In analogy to the electrical superheterodyne receiver, an optical superheterodyne receiver can be designed in which received light is superimposed by the light generated by a local laser. One condition for the superpositioning is, besides the use of coherent light, the same polarisation plane for both light waves. Because the polarisation plane of the light transmitted through the light wave conductor can change, an arrangement for controlling the polarisation on the receiver side is necessary. The polarisation control is carried out by means of double-refracting elements, which are formed using relays, whose movable armatures exert a variable pressure on a light wave conductor carried through the yoke of the magnet. In the present case one can manage with three such double-refracting elements that are controlled in such a way that even when one of these elements arrives at the limit of a displacement range, there is no abrupt change in the polarisation and consequently no signal failure.

Title: Probe for the reduction of pressure-shock effects in the interior of a hollow body
Inventor: SCHUBERT WERNER DR MED
IPC: F16L55/053
Filed: 1986-09-29
Abstract: The optimisation of the pressure-shock absorption in a relatively small space by means of a probe is possible by virtue of the fact that it is of inhomogeneous construction and combines a plurality of components which absorb pressure shocks, that, in particular, it contains gas spaces compressible by pressure shocks and that other elastic components, such as steel springs, are simultaneously stressed by the pressure shocks. The shell of the probe too can be composed of different materials, such as rubber or the temperature-insensitive material Teflon, and have roughness-increasing features on the outside; part of the shell can be manufactured from a strong material such as steel. It is likewise possible, as a safety device, to have a bursting disc or a recoil cylinder, additionally braked by a spring, at the front on a gas-containing probe. A pressure-shock-reducing probe with gas and springs can also be present on the inner surface of a conventional bursting disc.

Patent DE-3640956-A1 (DE)
Title: Method of determining the printing area for printing presses
Inventor: MORGENSTERN BERND
IPC: B41F33/00
Filed: 1986-11-29
Abstract: The object of the invention is to provide a method of measurement which provides more accurate results and extends the area of application. The object is therefore to reduce the effects due to irregularities occurring on the surface of the master and to eliminate the necessity for calibration blocks to be available. The object is achieved in that an area of known area coverage outside the printed-image area is measured for each sensor and stored. A measurement of the same area situated outside the printed-image area or of the test point is carried out with an additional filtering and the measured value is stored. During or after the point-by-point measurements in each ink-zone-wide column of the printed-image area, the measured values are normalised to the filter transmission curve. Then the position of the point in the printed-image area having the maximum blackening and the mean of all the normalised measurements are determined for the respective ink-zone-wide column and stored. The degree of area coverage of this point is determined and the degree of area coverage per column and, from the latter, the ink key presetting values are obtained from the stored values.

Patent DE-3716599-A1 (DE)
Title: Method and machine for recovery of waste heat and its harnessing as thermal power in piston heat engines
Inventor: BELLAN HEINRICH
IPC: F02B41/04
Filed: 1987-05-18
Abstract: According to this method, the warm exhaust gases leave the cylinder spaces by way of a regenerative heat exchanger, heating it up. By the interaction of several pistons whose motion is controlled and the heat exchanger, fresh air, perhaps cooled simultaneously, is compressed and then forced through the heat exchanger in the opposite direction than that in which the exhaust gases flowed. Fuel is injected into the thus heated, compressed air, and auto-ignites. The high pressure of the gas, due partly to the heat recovery and partly to the combustion of the fuel injected, drives the pistons, thus doing work. The thermal efficiency of the piston heat engine is substantially improved by this method, and complete combustion achieved, as well.

Title: Method of direct storage of a movement sequence in real time, and exact reproduction of this movement in both time and space
Inventor: LOEFFLER CHRISTIAN
IPC: G05B19/42
Filed: 1987-07-23
Abstract: The distinguishing feature of the method is that after the start key (Fig. 3, item 8) has been set to "write", the movement is captured by sensors (2) directly on the mechanically mobile device (1), and stored via a signal converter (3) directly into the memory (5), while the necessary address and signal management is done by the control logic (4). When the starter (8) is reset to "read" the reading procedure begins, in such a way that the recorded movement is exactly repeated. By this method, a movement sequence of arbitrary complexity can be recorded quickly and simply, and can be reproduced in time and space without errors or interpolations. <IMAGE>

Title: Method and facility for drying moist bulk materials in a fluidised-bed dryer
Inventor: KLUTZ HANS-JOACHIM DIPL ING
IPC: F26B3/084
Filed: 1987-07-28
Abstract: In known methods for drying moist bulk materials in a fluidised bed, an external energy-rich heating medium is supplied to the dryer, as well as the fluidising medium, while the vapours emitted remain unutilised. The method according to the invention is intended to avoid supplying heating media externally, to improve the energy balance, and to reduce the emission of vapours. A portion (15) of the flow of vapours (10) from which dust has been separated in the electrostatic precipitator (11) is used as a heating medium (18), and compressed to saturated steam in a compressor (14), with electricity being supplied and vapour condensate (29) being injected (17). A second portion (13) of the flow serves as a fluidising medium for the preheated bulk material (5) passed through the dryer (6). The preheating is done in a heat exchanger (2) through which a portion (3) of the vapour condensate (21) flows. After phase separation in a flashing vessel (4), the steam phase (23) of the condensate is fed into the partial flow (16). The method is particularly suitable for drying pit-wet raw brown coal or moist sewage sludge. <IMAGE>
