Patent EP-0307024-A1 (EP)
Inventor: JANSEN GEORG
IPC: C09K23/02
Filed: 1988-08-18
Abstract: The agent to be used for de-inking waste paper in the form of, for instance, old newspapers, pictorials, and the like, is an aqueous fatty acid-containing anionic dispersion which essentially contains saturated fatty acids, anionic surfactants as well as mono- and/or diesters of poly­valent alcohols of fatty acids having an HLB value of from about 3 to about 7. A preferred fatty acid is palmitic acid. A particularly suitable ester is commercial glycerin monostearate having a monoester content of 45-60 %. Use of the agent in de-inking results in a considerable improvement of the degree of whiteness of the remaining fibres and a reduction in the fibre losses during flotation. The agent may with advantage be used in continuous operation at a high recirculation rate of the process water.

Abstract: An orthopedic device of biocompatible polymer with oriented fiber reinforcement. There is provided a device such as a hip stem which has a longitudinally curved body. The reinforcing fibers (50-72) are continuous filament fiber plies (50-72) with parallel oriented fibers in each ply. The plies are curved longitudinally to approximately corre­spond to the curve of the body. There are longitudinally oriented fiber plies (54,72) at or near the surface of the device and plies (56-70) with fibers offset at 5-40° from the longitudinal axis between the surface layers. The fiber orientation is balanced by providing a ply of negatively angled offset fibers of a similar angle for each positively angled offsey ply. The device is made by molding plies preimpregnated with polymer (prepregs) simultaneously, by molding a plurality of prepregs into segments which are then molded together, or by molding a segment and increment­ally molding additional layers of prepregs thereto in a series of progressively larger molds.

Abstract: A current source circuit capable of generating two currents of opposite polarities. In order to generate the two currents, the circuit comprises a current source stage (M3-M5) including a current mirror and feeding a first output current (I OUT1 ) and an inverter stage (M6-M9) connected to the source stage and generating a second output current (I OUT2 ) with opposite polarity with respect to the first. The inverter stage comprises a current mirror (M6-M7) and a variable current source (M8-M9) defining a control electrode. In order to eliminate the differences in the amplitude of the output currents, the inverter stage comprises a memory element (C) connected to the control electrode so as to store an electrode controlling signal. Switch elements (SW1-SW4) are furthermore interposed between the first output and the second output so as to short-­circuit them during the trimming step so that the two output currents are equal to one another while the memory element memorizes the control signal. This signal remains stored during the normal operation of the circuit.
