Title: Method for the hybrid adaptive equalisation of high-speed digital transmission systems, using a bit pattern detector
Inventor: MAIER MARTIN DIPL ING
IPC: H04L25/03
Filed: 1985-01-18
Abstract: To adjust an adaptive equaliser for high-speed digital transmission channels, the receiving signal is not continuously evaluated but the data signal is monitored by means of a detection circuit, in the method described here, and when certain bit sequences (e.g. 0001000) occur, the associated analog values of the received signal at the time of decision are made accessible to computer evaluation. The bit pattern detection is also controlled by the computer, as a result of which any bit sequence can be set for the comparison with the data signal. The analog-value detection is based on iterative threshold comparison and is activated whenever correspondence is indicated by a release pulse from the bit pattern detection circuit. The individual samples are not measured at the bit spacing T, but a single analog value is determined for each release signal from the bit pattern detection circuit, as a consequence of which the noise interference in the individual analog values is generally uncorrelated due to the long time intervals. In addition, this method can be used for measuring the rms noise level and the signal/noise ratio during the data transmission.

Patent DE-3612464-A1 (DE)
Title: Electrical earthworm trap using the octet method
Inventor: THIELEMANN ULI DIPL BIOL
IPC: A01K67/033
Filed: 1986-04-14
Abstract: The octet method makes it possible to detect earthworm populations quantitatively as well as qualitatively. The method is based on electrodynamic interrelationships since it has been derived from a plate capacitor which produces a homogeneous electric field. Each electrode of the circular electrode octet arrangement has a separate electrical power supply. This makes it possible to connect electrode combinations which produce a relatively homogeneous electric field in the ground and result in the current flow direction changing eight times. In consequence, all the earthworms, which are in different orientation positions in the ground, are subjected to the same conditions in the electric field. A control panel contains eight switches for the electrodes, an ammeter, a voltmeter and a dimmer for continuously variable voltage regulation. Only the low voltages of 30V and 60V are necessary to obtain quantitative results. In order to determine the effectiveness of the method, the earthworms were dug out manually, down to an underground depth of 0.5 m, after being trapped electrically. Of the total number of earthworms extracted, 87.7% were detected using the octet method.

Title: Arrangement for representation of windows on a screen of display unit
Inventor: BEHRENS HERBERT
IPC: G06F3/0481
Filed: 1986-05-30
Abstract: Programs which run on screen-oriented workstations use the windowing technique. If several windows are opened, the windows which are opened first are partly or completely covered by the windows which are opened later. Thus, the operator cannot know the contents of the covered windows unambiguously. The way in which this disadvantage is removed by the invention is that the screen (1) has a useful display area (3) to display windows (4, 5, 6, 7) with specific contents, such as appointments diary, address management, calculation, menus, and a window identification area (8) to display identification windows (9, 10, 11, 12) of the opened windows (4, 5, 6, 7). By looking at the identification windows, the operator can immediately know the number and contents of the windows (4, 5, 6, 7) which are open in the useful display area (3). Simply by touching an identification window (9, 10, 11, 12), the assigned window (4, 5, 6, 7) in the useful display area (3) can be very simply prepared for processing. <IMAGE>

Title: Process for reducing metal oxides and plant for carrying out the process
Inventor: JANGG GERHARD PROF DR
IPC: F27B14/00
Filed: 1986-10-28
Abstract: In a process for reducing metal oxides, metal oxides are reacted under vacuum with carbon carriers in a bath of auxiliary metal which has a lower affinity for oxygen than the metal of the oxide to be reduced. In order to be able to reduce the oxides with a short reduction time and low energy consumption, the reaction of the metal oxides with the carbon carriers is carried out at the boiling temperature of the auxiliary metal. The resulting mixture comprising auxiliary metal and CO gas is cooled in a condenser (3) and the condensed liquid auxiliary metal is returned to the bath, an alloy being formed on feeding metal oxides and carbon carriers into the liquid bath, which alloy comprises auxiliary metal and reduced metal and is enriched in the latter and is taken off from the reduction vessel (2) (Fig. 1). <IMAGE>

Title: Coupling arrangement on a tractor
Inventor: BREU JOHANN
IPC: B60D1/02
Filed: 1987-02-26
Abstract: In the case of road trains with rigid drawbar trailers, when the permissible, vertical pivoting angle is exceeded there is the risk of the coupling arrangement being destroyed. The intention of the invention is to provide a coupling arrangement which avoids this type of destruction. To this end, it is proposed that the coupling element (3) can be deflected in a pivoting manner, by means of an overload torque exerted on it by the drawbar (6), out of an essentially rigid normal position for normal operation with an essentially horizontal drawbar eye-introduction direction, into a vertical pivoting plane parallel to the general direction of travel, whilst maintaining the towing connection between the coupling element (3) and the tractor. <IMAGE>
Patent DE-3707093-A1 (DE)
Title: Sweeping machine
Inventor: GRUENIG DIETER
IPC: E01H1/08
Filed: 1987-03-05
Abstract: A sweeping machine has in a housing (1) a drivable horizontal brushing roller (6). In the housing (1), a dirt receptacle (7) is open towards the brushing roller (6). Located above the dirt receptacle (7) is an air opening (12) which leads approximately tangentially away from the circumference of the brushing roller (6) and passes into an air channel (13) having a dust filter (14) and leading into an air outlet opening (15). A flexible sealing apron (4), which lies on the ground, is attached to the bottom edge (3) of the housing (1) so as to run all the way round. The brushing roller (6) generates an air current which is directed into the air channel (13) towards the air outlet opening (15) and which generates a negative pressure in the housing (1) in the region of the brushing roller (6). This negative pressure prevents the escape of dust. <IMAGE>
