20120283345 | HEAT-RESISTANT AND FLAME-RETARDANT EXTRUDED FOAM MADE OF STYRENE COPOLYMERS - The invention is directed to extruded foam based on thermoplastic polymers. The foam contains at least one styrene copolymer which contains copolymerized maleic anhydride units or copolymerized maleimide units, and optionally styrene-acrylonitrile copolymers (SAN), and thermoplastic polymers and at least one halogen-containing polymer as flame retardant, and at least one flame retardant synergist selected from antimony trioxide and dicumyl. The invention also relates to a process for producing the foam with introducing carbon dioxide as blowing agent, and acetone as coblowing agent; into the polymer melt in order to form a foamable melt, and extruding the foamable melt into a region of relatively low pressure with foaming to give the extruded foam. The invention also relates to the use of said foam as insulation material and as structural foam. | 11-08-2012 |

20130184779 | VOLTAGE LIMITED NEUROSTIMULATION - Methods and systems for delivering voltage limited neurostimulation to a patient. In one aspect, a method includes initiating a flow of electrical current through a first electrode and a second electrode coupled to the patient and increasing the flow of electrical current toward a target value by increasing a voltage across the first electrode and second electrode. Prior to reaching the target value of electrical current, the method includes preventing the voltage across the first electrode and second electrode from increasing beyond a first predetermined limit; and subsequently, maintaining the voltage across the first electrode and second electrode at or within a predetermined range that does not exceed the first predetermined limit. The amplitude of the electrical current continues to increase toward the target value during at least part of a time when the voltage across the first electrode and the second electrode is maintained within the predetermined range. | 07-18-2013 |
