20130210950 | REACTION SYSTEM FOR PREPARING POLYURETHANE MICROCELLULAR FOAM, A POLYURETHANE MICROCELLULAR FOAM AND THE USE THEREOF - The present invention relates to a reaction system for preparing polyurethane microcellular foam, a polyurethane microcellular foam and the use thereof. The reaction system for preparing polyurethane microcellular foam comprises isocyanate prepolymer, polyols, catalysts and chain extenders. The isocyanate prepolymer is a reaction product of polyisocyanates and polyester polyols, wherein the polyester polyols comprise 10-60 wt. % succinic acid units, based on 100 wt. % of the polyester polyols, the NCO content of the isocyanate prepolymer is 13-30 wt. %, based on 100 wt. % of isocyanate prepolymer. By using the reaction components provided in the present invention, the demould time for preparing the polyurethane microcellular foam can be reduced. The obtained polyurethane microcellular foam, which possesses good physical and mechanical properties, is particularly suitable to prepare shoes. | 08-15-2013 |
20150183949 | MICROCELLULAR POLYURETHANE COMPOSITION, METHOD OF PREPARATION AND USES THEREOF - The present invention, which is characterized by the employment of blowing agents comprising fluorinated ethers with a boiling point in the range of from about 0 DEG C to 75° C., pertains to a composition of microcellular polyurethane, a method for preparing the same, and its use in manufacturing shoe materials. Compared to shoe soles made from traditional microcellular polyurethane, in particular those made using 1,1,1,2-tetrafluoroethane (HFC 134a) as the blowing agent, the polyurethane shoe soles prepared according to the present invention exhibit similar shrinkage characteristics, and their linear shrinkage is compatible with the current processing conditions, thus can replace traditional blowing systems comprising 1,1,1,2-tetrafluoroethane (HFC 134a) in shoe manufacturing without the need of changing molds. On the premise of being more environmental-friendly, the present invention also effectively saves production cost for shoe manufacturers. | 07-02-2015 |

20140025842 | BACNET MS/TP AUTOMATIC MAC ADDRESSING - A building automation and control network (BACnet) master-slave/token-passing (MS/TP) automatic media access control (MAC) addressing system having a BACnet MS/TP network, a MAC assigner on the network, and one or more MAC assignees on the network. Each assignee may have a global unique identity (GUID) and the assigner may have a pre-defined address. The assigner may gather virtually all GUIDs of the MAC assignees on the network and gather virtually all unused MAC addresses on the network. The assigner may map GUIDs to the unused MAC addresses and send a resulting map to the MAC assignees for assignment of a MAC address to each assignee. Each assignee may be assigned a MAC address according to its GUID, and the assignment of a MAC address to each assignee may occur automatically without manual intervention. In other words, the system may provide auto MAC addressing. | 01-23-2014 |

20150076695 | SELECTIVE PASSIVATION OF VIAS - A method of forming an integrated circuit structure includes forming a cap layer above a first ILD layer of a first metal level, the first ILD layer includes a recess filled with a first conductive material to form a first interconnect structure. Next, a second ILD layer is formed above the cap layer and a via is formed within the second ILD layer as a second interconnect structure of a second metal level. The via is aligned with the first interconnect structure. Subsequently, a portion of the cap layer is removed to extend the via to expose a top portion of the first conductive material then a passivation cap is selectively formed at a bottom portion of the via in the second ILD layer and the passivation cap contacting the top portion of the first conductive material. The passivation cap includes a metal alloy to form an interface between the bottom portion of the via and the first conductive material. | 03-19-2015 |
