20150322213 | NCO-MODIFIED POLYOXYMETHYLENE BLOCK COPOLYMERS - The invention relates to a method for producing NCO-modified polyoxymethylene block copolymers comprising the step of polymerizing formaldehyde in a reaction vessel in the presence of a catalyst, the polymerization of formaldehyde in addition taking place in the presence of a starter compound comprising at least 2 Zerewitinoff active H atoms to obtain an intermediate product. The intermediate product obtained is reacted further with an isocyanate to obtain an NCO-modified polyoxymethylene block copolymer. The invention also relates to NCO-modified polyoxymethylene block copolymers obtained by a method of this type and to the use of said copolymers for producing polyurethane polymers. | 11-12-2015 |
20150368396 | FUNCTIONALIZED POLYOXYMETHYLENE BLOCK COPOLYMERS - The invention relates to a method for producing functionalized polyoxymethylene block copolymers comprising the step of polymerizing formaldehyde in a reaction vessel in the presence of a catalyst, the polymerization of formaldehyde in addition taking place in the presence of a starter compound comprising at least 2 Zerewitinoff active H atoms, to obtain an intermediate product. The intermediate product obtained is subsequently reacted with a cyclic carboxylic acid ester or carbonic acid ester, thus obtaining a functionalized polyoxymethylene block copolymer. The invention further relates to functionalized polyoxymethylene block copolymers obtained by such a method and to the use of said copolymers. | 12-24-2015 |

20160130407 | POLYETHERCARBONATE-POLYOXYMETHYLENE BLOCK COPOLYMERS - The present invention relates to a method for producing polyethercarbonate-polyoxymethylene block copolymers, comprising the step of polymerizing formaldehyde, wherein formaldehyde is polymerized in the presence of a polyethercarbonate having at least one Zerewitinoff-active H atom, obtaining an intermediate product. The obtained intermediate product can be further reacted with a cyclic carboxylic acid ester or carbonic acid ester, a cyclic anhydride, an epoxide, and/or an isocyanate, wherein a hydroxyl- or carboxy-functional or NCO-modified polyethercarbonate-polyoxymethylene block copolymer is obtained. The present invention further relates to polyethercarbonate-polyoxymethylene block copolymers that can be obtained by means of such a method and to the use of same to produce polyurethane polymers. | 05-12-2016 |

20120288110 | Device, System and Method of Noise Control - Some demonstrative embodiments include devices, systems and methods of noise control. For example, a device may include a controller to control noise within a predefined noise-control zone, the controller is to receive a plurality of noise inputs representing acoustic noise at a plurality of predefined noise sensing locations, which are defined with respect to the predefined noise-control zone, to receive a plurality of residual-noise inputs representing acoustic residual-noise at a plurality of predefined residual-noise sensing locations, which are located within the predefined noise-control zone, to determine a noise control pattern, based on the plurality of noise inputs and the plurality of residual-noise inputs, and to output the noise control pattern to at least one acoustic transducer. | 11-15-2012 |
20160111078 | APPARATUS, SYSTEM AND METHOD OF CONTROLLING NOISE WITHIN A NOISE-CONTROLLED VOLUME - Some demonstrative embodiments include devices, systems and methods of noise control. For example, a noise control system may be configured to process one or more first noise inputs from one or more first acoustic sensors, the one or more first noise inputs representing external noise sensed at one or more respective noise sensing locations on an outer surface of a sheltering structure; to process one or more second noise inputs from one or more second acoustic sensors, the one or more second noise inputs representing residual noise at one or more respective residual noise sensing locations on an inner surface of the sheltering structure; to determine a noise control pattern based at least on the one or more first noise inputs and the one or more second noise inputs; and to generate one or more control signals to control acoustic signals generated by one or more acoustic transducers based on the noise control pattern. | 04-21-2016 |

20100152702 | METHOD FOR DELIVERING MEDICATION INTO AN ARTERIAL WALL FOR PREVENTION OF RESTENOSIS - A method for preventing a restenosis within a vessel wall requires a medicament be delivered at predetermined locations into the vessel wall and allowed to subsequently disperse in a predetermined pattern. To deliver the medicament, a catheter with an expanding member is advanced into the vasculature of a patient until the expanding member is located as desired. The expanding member is then expanded to force dispensers into the vessel wall to the proper depth. A medicament is then pumped through the dispensers to create a plurality of equally spaced, localized medicinal deliveries which subsequently disperse to medicate an annulus shaped volume within the vessel wall. | 06-17-2010 |
