  • Patent number: 11939280
    Abstract: A method for preparing isophorone diisocyanate by (1) reacting isophorone with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile; (2) reacting the isophorone nitrile obtained in step (1) with ammonia gas and hydrogen in the presence of a catalyst to obtain isophorone diamine; and (3) subjecting the isophorone diamine to a phosgenation reaction to obtain the isophorone diisocyanate, wherein the content of impurities containing a secondary amine group in the isophorone diamine that undergoes the phosgenation reaction in step (3) is ?0.5 wt. The method reduces the content of hydrolyzed chlorine in the isophorone diisocyanate product, improves the yellowing resistance of the product, and the harm due to presence of hydrolyzed chlorine in the product is reduced.

  • Patent number: 10548769
    Abstract: Provided is a glaucoma valve, a casing for containing a glaucoma valve and a glaucoma drainage device including the glaucoma valve and/or the casing. The valve includes a flow channel having an inlet and an outlet and a valve member connected to the outlet of the flow channel. The valve member may be formed from a degradable polymer or a combination of degradable polymer and non-degradable polymer. The valve may have a first flow channel, the interior of which may be coated with a degradable polymer, such that in use, the polymer degrades to allow a greater flow of fluid through the flow channel. The valve may include a second flow channel, which may be arranged in parallel to the first flow channel. The casing may be formed from a degradable polymer, such as a biodegradable polymer.

  • Patent number: 9408255
    Abstract: Embodiments of the present invention disclose a method for migrating a user plane from an Iur-g interface to an A interface and an apparatus. The method includes: receiving, by a BSC, a migration commit notification that is sent by an RNC through an Iur-g interface, where the migration commit notification is sent by the RNC according to a notification message of finishing preparing resources by the BSC, and the notification message of finishing preparing resources by the BSC is sent by a core network; and migrating, by the BSC, a user plane from the Iur-g interface to an A interface according to the migration commit notification. In this way, the interruption duration in a process of migrating the user plane from the Iur-g interface to the A interface may be shortened.

  • Publication number: 20130211314
    Abstract: Various embodiments of the invention relate to a glaucoma valve, a casing for containing a glaucoma valve and a glaucoma drainage device comprising the glaucoma valve and/or the casing. The valve includes a flow channel having an inlet and an outlet and a valve member connected to the outlet of the flow channel. The valve member may be formed from a degradable polymer or a combination of degradable polymer and non-degradable polymer. Various embodiments of the invention relate to a glaucoma valve, the valve having a first flow channel. The interior of the first flow channel may be coated with a degradable polymer, such that in use, the polymer degrades to allow a greater flow of fluid through the flow channel. In some embodiments, the valve includes a second flow channel, which may be arranged in parallel to the first flow channel. The first flow channel may be completely sealed with the polymer such that in use, the polymer degrades to allow fluid to flow through the first flow channel.
