Patent HU-206766-B (HU)
Title: Renovating machine for repairing and sealing impassable pipings
Inventor: SIGEL ALWIN
IPC: F16L55/18
Filed: 1987-11-27
Abstract: The invention in question is a repairing machine, which is suited to repairing damaged conduits which are inaccessible for repair work. This repairing machine is remote-controlled and monitored with television cameras. At the head of the driving carriage, various devices, which are necessary for the repairs, can be attached to a motor-driven rotatable toolhead. A simple construction of the movable head has made it possible to accomplish all of the necessary movements with uncomplicated mechanics, and at the same time, to forego a tedious slide coupling for the control lines without letting them get tangled with the device. Therefore, with this invention, the production costs for the whole device could be lowered and, likewise, the proneness to repairs could be reduced.

Trigger pulses for a bi-stable circuit are directed along one or other of two paths under the control of clock pulses, the path used being dependent upon whether or not input signals are present on the input terminals of an AND gate. As shown in Fig. 2, trigger pulses to bi-stable circuit FF are applied at terminal IN1 or IN2 dependent upon whether or not input signals are applied to terminals L 1 , L 2 , L 3  of an AND gate comprising diodes G 1 , G 2 , G 3 . If negative-going input pulses are present at terminals L 1 , L 2 , L 3  then when clock pulses Lc, Fig. 3, are applied to the circuit the potential at the point a changes as shown, and a trigger pulse is generated at b at the trailing edge of the clock pulse and applied to terminal INI of the bi-stable circuit FF. The potential of the second trigger output point c does not rise above earth so that no trigger pulse is passed through diode Db to input terminal IN2. If there is no input signal on the logical AND circuit the potential of the point a does not change, but that at c does upon the arrival of the clock pulse Lc and a trigger pulse C<SP>1</SP> is generated at the trailing edge of the clock pulse and passed through diode Db to terminal IN2 to switch the bi-stable circuit.

Title: Testing method for determining the magnetic properties of ferromagnetic powders
Inventor: KARLHEINZ UHLE
IPC: G01N27/72
Filed: 1981-05-15
Abstract: The invention relates to a method permitting ferromagnetic powders for use in heavy medium suspensions for the float-sink dressing of minerals to be readily tested as to their efficiency in magnetic separation and demagnetization. To this end, the invention provides (a) for a heavy medium suspension specimen to be removed from the purification cycle directly downstream of the magnetic separation stage, for it to be freed from impurities by decantation, and its relative sedimentation velocity to be determined with the aid of a sedimentometer; (b) for a heavy medium suspension specimen to be removed from the purification cycle downstream of the demagnetization stage, for it to be freed from impurities by decantation, and for its relative sedimentation velocity to be determined with the aid of a sedimentometer; and (c) for the heavy medium suspension specimen according to (b) to be demagnetized in a cyclicly decreasing magnetic alternating field with a maximum field strength which is 1.1 to 1.5 times the maximum field strength of the magnetic separator, and for the relative sedimentation velocity of the specimen to be determined with the aid of sedimentometer. The ferromagnetic powder is reliably separable magnetically and demagnetizable with the aid of a demagnetizing means in the event of the relative sedimentation velocity according to (a) being at least ten times greater than the relative sedimentation velocity according to (c), and the relative sedimentation velocity according to (c) being at most 10% lower than that according to (b).
