After any drying that might be necessary, and renewed suspension/dispersion in an organic solvent, the magnesium hydroxide particles are worked into a component of a curable mass. Furthermore, the present invention is directed at a method for the production of a cured polymer material. Finally, the present invention makes available curable masses, polymer materials produced from them, particularly duroplastics or thermoplastics, as well as composite material containing curable masses or polymer materials produced according to the invention, as well as reinforcement agents. | 01-07-2010 |
20100011993 | Method for the production of coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles - The present invention relates to a method for the production of coated magnesium hydroxide particles, whereby the individual primary magnesium hydroxide particles are coated. According to the invention, specific additives are added to the precipitation reaction for obtaining the magnesium hydroxide particles, in order to obtain these magnesium hydroxide particles in a coated state. Furthermore, a first method step of the present invention is directed at a method for the production of coarse-scale or nanoscale, coated magnesium hydroxide suspensions or dispersions. In a second method step, the coated magnesium hydroxide particles can be converted to de-agglomerated products either by means of bead-mill grinding or ultrasound and a dispersant. Finally, the present invention is directed at coated magnesium hydroxide particles, particularly nanoscale, coated magnesium hydroxide particles that can be obtained in this manner. | 01-21-2010 |
20100038817 | Device, production and method for thermoplastic polymers containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles - A method and device for the production of thermoplastics containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles that are supplied to the thermoplastic in the form of a dispersion or suspension in an aqueous or organic solvent, and mixed with the themoplastic. The thermoplastics filled with magnesium hydroxide particles demonstrate improved mechanical properties, particularly an improved modulus of elasticity and low brittleness. | 02-18-2010 |

20110102159 | SYSTEMS AND METHODS FOR CONTROLLING COMMUNICATION OVER A POWER DISTRIBUTION NETWORK - An embodiment of a communication system can control transmission of a data signal to a power distribution network based on signal data measured from the power distribution network. The signal data may represent an amount of crosstalk or an amount of noise experienced on the power distribution network. The signal data and an identification of at least one active power line coupler unit can be used to determine an adjustment to one or more power line coupler units. A control signal that represents the adjustment can be used to adjust the power line coupler units. | 05-05-2011 |
20130163682 | POWERLINE COMMUNICATION RECEIVER - Aspects of the present disclosure are directed towards a circuit-based apparatus for receiving data communications over power distribution lines that carry power using alternating current (AC). The apparatus has a processing circuit that is configured and arranged to receive an input signal representing the data communications over power distribution lines. For a quadrature encoded signal, the input signal is separated into intermediary signals representing a real portion of and an imaginary portion. The processing circuit can then determine timing information from the real portion of and the imaginary portion. The intermediary signals can then be decimated according to a variable rate of decimation that is responsive to the determined timing information. The decimated intermediary signals are also filtered. | 06-27-2013 |
