Patent EP-0035122-B1 (EP)
IPC: G01N27/72
Filed: 1981-02-03
Granted: 1984-04-11
Abstract: The invention relates to a method permitting the magnetic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention provides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pretreated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the circular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the alternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited qualification of the ferromagnetic powder for use in a heavy medium suspension.

The latter is a low-molecular weight, optionally modified 1,3-butadiene polymer which carries quaternary ammonium groups. This polymer is obtained by reacting an epoxy-group-containing polymer with a secondary and/or primary aliphatic amine and reacting the amination product with a low-molecular weight monoepoxide, during which process 0.05-0.5 mole of the quaternizable amino groups is quaternized per 100 g of the amination product.

Granted: 1985-11-27
Abstract: A communication system signaling method and arrangement utilizing direct current signaling over the line loop connecting a line terminal to a central office. The direct current provides concurrent active/inactive line terminal condition signaling and analog/digital information transmission mode signaling between the terminal and central office. A current flow in a first direction over the line loop signals the analog mode, while a current flow in the opposite direction signals the digital mode. A change in the operating mode is signalled by blocking current flow at the line terminal. The resulting interruption of current flow is detected at the central office which responds by reversing the direction of current flow over the line loop. Current flow in the line loop indicates the active (off-hook) condition of the line terminal, while the absence of current flow for a predetermined interval indicates the inactive (on-hook) condition.
