Patent DE-3230268-A1 (DE)
Title: Antenna arrangement for direction-finding systems on masts
Inventor: MOENICH GERHARD DR ING
IPC: G01S3/10
Filed: 1982-08-14
Abstract: Electrical antennas which are arranged on masts are coupled in an undesirable manner to the mast current via the secondary field of the mast. The mast coupling can be overcome by means of a second antenna which is arranged in addition to the actual receiving antenna in the vicinity of the mast and receives the primary field of the incident wave with the same mathematical sign, and the secondary field of the back-scattered wave, but with the opposite mathematical sign to the first antenna, and by combining the two antenna voltages after adjustable weighting of the voltage amplitudes.

IPC: G01R23/15
Filed: 1983-08-03
Abstract: The invention relates to a circuit arrangement for detecting frequencies of a supplied signal (1, 11) and for controlling a switching element (13) in dependence on the frequency. A control element (2) is set by edges of the supplied alternating-frequency signal (1, 11) and remains in the set state for a fixed period of time (t1), as a result of which a frequency-dependent signal (3, 33) is present at its output (22). The latter is connected to the input (41) of a memory chip (4), the output of which (42) carries a One signal or a Zero signal and controls a switching element (13) via a transistor (12). It is provided that the control element (2) is connected at its loading time input (23) to a first RC element (5) which determines the reset time (t1). The memory chip (4) is set by edges of the frequency-dependent signal (3, 33). Its loading time input (43) is connected to a second RC element (6) which determines the reset time (t2). A further output (24) of the control element (2) is connected via a diode (19) in forward direction and an ohmic resistor (9) to the loading time input (43) of the memory chip (4). As a result, the reset time (t2) of the memory chip (4) is reduced and the switching element (13) is switched off delayed by the reduced reset time (t3). <IMAGE>

Title: Method of estimating stresses liable to cause rock burst, and a measuring device
Inventor: BRAEUNER GERHARD DR ING
IPC: E21F17/18
Filed: 1983-08-26
Abstract: To estimate stresses liable to cause rock burst, the torque and the applied pressure, in addition to the energy expended and the speed of the drilling tool, are also measured and analysed. There are thus two partial measuring methods which take place independently of one another and which largely eliminate both technical shortcomings and human inadequacies. Serving to carry out the method is a measuring device in which a dynamometer for determining the applied pressure and if necessary a measuring shaft for determining the torque are allocated to the drilling machine.

Title: Process for the production of a highly concentrated MgCl2 product solution
Inventor: SCHMITZ REINER DIPL ING
IPC: C01F5/30
Filed: 1983-12-15
Abstract: In the potash industry, the production of potassium chloride gives rise to magnesium chloride solutions which, in addition to the main component MgCl2, disadvantageously also contain dissolved potassium chloride, sodium chloride and magnesium sulphate in relatively high concentrations. In order to produce a concentrated magnesium chloride brine of sufficient purity, the brine is blended, in a first process step, with a carnallite/sodium chloride crystal mixture, recycled from a subsequent third process step, in order to decompose the carnallite, the brine then being separated from the crystals and, as a clear solution in a second process step, being boiled down and kieserite being separated, followed by crystallisation by cooling as a third process step. Between the first and second process step an additional salting-out process step is incorporated, in which some or all of the clear solution is mixed with MgCl2 product solution recycled from the third process step, and the carnallite/NaCl crystal mixture separated by salting out is recycled into the first process step of carnallite decomposition, while the solution is again combined with the clear solution from the first process step.

Title: Apparatus for the fibrous comminution of stalk material
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01F29/00
Filed: 1984-03-21
Abstract: Known comminuting apparatuses for stalk material, which cut away bales of stalk material with finely toothed implements, have the disadvantage that the stalk material is removed jerkily and is therefore comminuted unevenly. Finally, a jamming of the cutting rotor can occur. These disadvantages are eliminated in that discs are arranged between the cutting tools and support the bale of stalk material, and in that the cutting tools project beyond these discs approximately by the amount of a tooth depth.
