20090159333 | DETERMINING DRILLSTRING NEUTRAL POINT BASED ON HYDRAULIC FACTOR - A solution for determining a neutral point of a drillstring in drilling a borehole is disclosed. A method may comprise: receiving depth-time log data for drilling the borehole with the drillstring, the depth-time log data including data related to a torque and drag factor and data related to a hydraulic factor; and determining the neutral point of the drillstring at a time point during the drilling based on the torque and drag factor and the hydraulic factor. | 06-25-2009 |
20100163306 | Modeling Vibration Effects Introduced By Mud Motor - Torsional, axial and lateral vibrations introduced when a mud motor is used with a drilling tool to drill a borehole are calculated using a model. The model includes different computational modules for each of three distinct motor sections: power, transmission and bearing. The resulting calculated vibration effects are used to enhance the drilling tool and drilling operation. | 07-01-2010 |
20110027345 | COMPOSITION CONTAINING ROTIGOTINE AND USE THEREOF AND TRANSDERMAL PATCH CONTAINING THE COMPOSITION - The present invention relates to a composition containing Rotigotine and the use thereof in the manufacture of a Rotigotine-containing transdermal patch, wherein said composition is based on a matrix mixture system formed from a combination of an acrylic pressure-sensitive adhesive with a silicone pressure-sensitive adhesive, and polyvinylpyrrolidone which are present in a particular weight ratio, wherein (1) the acrylic pressure-sensitive adhesive is present in an amount of about 1-25% by weight in the matrix mixture system, (2) the silicone pressure-sensitive adhesive is present in an amount of about 65-98% by weight in the matrix mixture system, and (3) the polyvinylpyrrolidone is present in an amount of about 1-10% by weight in the matrix mixture system, and comprises 1-40% of Rotigotine on the basis of the total weight of the composition. The present invention further relates to an improved transdermal patch containing Rotigotine comprising said composition. Said patch has improved properties in the solubility, release and initial penetration level of Rotigotine. | 02-03-2011 |
20130202513 | Ce-BASED COMPOSITE OXIDE CATALYST, PREPARATION METHOD AND APPLICATION THEREOF - Disclosed is a Ce-based composite oxide catalyst for selective catalytic reducing nitrogen oxides with ammonia, which comprises Ce oxide and at least one oxide of transition metal except Ce. The Ce-based composite oxide catalyst is prepared by a simple method which uses non-toxic and harmless raw materials, and it has the following advantages: high catalytic activity, and excellent selectivity for generating nitrogen etc. The catalyst can be applied in catalytic cleaning plant for nitrogen oxides from mobile and stationary sources. | 08-08-2013 |
20140211714 | METHOD AND APPARATUS FOR PERFORMING POLICY CONTROL ON DATA PACKET - A method and an apparatus are provided for performing policy control on a data packet. The method includes: allocating, by a local gateway, a port range to a UE, where the port range is unique to the UE; sending, by the local gateway, the port range of the UE and user information to a policy server, so that the policy server makes a policy rule for the UE, where the policy rule contains the port range; and performing, by the local gateway, network address translation on a packet sent by the UE, so that a source port of the converted packet is in the port range, and sending the converted packet to a network gateway in a fixed network, so that the network gateway performs policy control on the packet according to the policy rule received from the policy server. | 07-31-2014 |
20150063310 | Method and Apparatus for Removing Policy and Charging Control Rule from Default Bearer - The present invention provides a method and an apparatus for removing a policy and charging control rule from a default bearer. The method includes: determining whether a received service flow is a service flow of SRVCC switching upon receipt of flow description information of the service flow; and, if the received service flow is the service flow of the SRVCC switching, removing a policy and charging control rule that has been activated on a default bearer for the SRVCC switching, and at the same time issuing a policy and charging control rule made for a newly created bearer. | 03-05-2015 |
20150092786 | SESSION ESTABLISHMENT METHOD AND APPARATUS - The present invention is applicable to the field of communications and provides a session establishment method and apparatus. The method includes: acquiring an infrastructure virtual circuit IVC corresponding to a user equipment UE; sending a virtual local area network VLAN label corresponding to the IVC to a customer location function set, so that the customer location function set adds the VLAN label to a packet of the UE, where the VLAN label is configured by an L2 session control functional entity for the IVC; and notifying an L2 forwarding functional entity of the VLAN label, so that the L2 forwarding functional entity forwards, to the IVC, the packet sent by the customer location function set and added with the VLAN label. In the present invention, a case in which the L2 forwarding functional entity needs to store a large MAC table is avoided, and packet forwarding efficiency is improved. | 04-02-2015 |
