Title: Polycrystalline ultra-hard material with microstructure substantially free of catalyst material eruptions
Inventor: FANG YI
IPC: C30B30/00
Filed: 2006-12-20
Granted: 2016-02-02
Abstract: Polycrystalline ultra-hard materials and compacts comprise an ultra-hard material body having a polycrystalline matrix of bonded together ultra-hard particles, e.g., diamond crystals, and a catalyst material disposed in interstitial regions within the polycrystalline matrix. The material microstructure is substantially free of localized concentrations, regions or volumes of the catalyst material or other substrate constituent.  The body can include a region extending a depth from a body working surface and that is substantially free of the catalyst material. The compact is produced using a multi-stage HPHT process, e.g., comprising two HPHT process conditions, wherein during a first stage HPHT process the catalyst material is melted and only partially infiltrates the precursor ultra-hard material, and during a second stage further catalyst material infiltrates the precursor ultra-hard material to produce a fully sintered compact.

Abstract: An applicator roll (1) is described for a labeling apparatus for paying out and applying self-adhesive labels, which with each operating cycle moves one self-adhesive label into a dispensing position underneath an applicator roll.  Depending on the printing mechanism used in the labeling apparatus, whether printing an even or an odd number of digits, it is advantageous to arranged a profiled ring (32) formed on a sleeve (31) of the applicator roll (1) in the center or off center. In addition, label formats of different widths require applicator rolls of different widths. These problems are solved in the applicator roll (1) described here in that its sleeve (31) supports two cylindrical jackets (34) on either side of the profiled ring (32). The cylindrical jackets (34) are axially displaceable on the sleeve (31) and can be releasably, positively locked in several positions against axial shifting, preferably by mutual engagement of an annular collar (38) and an annular groove (40). In this way, the applicator roll (1) can be adapted to printing mechanisms with even or odd numbers of digits and to labels of different widths.

Abstract: A system and method for access control is provided. In one embodiment, a system includes a computing device connected to an access server that controls the ability of the computing device to access to a computing resource, such as the Internet.  The access server connects to an activation server via a network. The activation server is operable to receive a request for to generate a certificate for the computing device from the activation server. The activation server is operable to generate the certificate and embed a unique identifier of the computing device and/or the access server and/or the like inside the certificate. Once generated, the certificate is installed in the computing device. When the computing device initiates a request to access the computing resource, the computing device initially sends the certificate to the access server. If the certificate received by the access server does not include the expected unique identifier(s), then access to the computing resource is prevented and/or restricted. If the key received by the access server includes the expected unique identifier(s), then access to the computing resource is permitted.

Abstract: The invention relates to a method for forming a highly electroconductive surface on an aluminium piece. A highly conductive layer of silver is formed on the piece by means of a eutectic join. The temperature of the aluminium piece is raised gradually and the oxide layer formed on the surface of the piece is removed. After the first heating stage, the silver piece that is to be attached is transferred to the cleaned surface. The contact point is heated to a temperature where a eutectic bond is generated between the aluminium and silver. During the second heating stage a slight momentary loading is applied to the contact point.

Abstract: A workholding apparatus includes a body, and a workholding sleeve composed of metal and carried by the body. A fluid chamber receives a fluid between the body and the workholding sleeve. Under fluid pressure, the sleeve is radially displaceable and recoverable to a high degree. For example, the sleeve is radially displaceable to at least one percent in diameter with runout within about 0.03% of its diameter, and after release of fluid pressure repeatably recovers to within about 0.01% of its original relaxed diameter. In another example, when displaced under fluid pressure, the sleeve experiences substantially complete and repeatable strain recovery of at least about 2% of its overall cross-sectional area. Preferably, the sleeve is composed of Nitinol.

Abstract: A wireless connection between a mobile device and an IP -based wireless telecommunications network is established when the mobile device registers with a network controller (NC) through an access point (AP). When a geographical position is needed for the mobile device (e.g., a 911 call), messages are exchanged between the NC and a serving mobile location center (SMLC), where the SMLC retrieves information from a database that is used to identify the geographic position of the mobile device. The database can store a variety of information related to mobile devices such as: last known position, IP address, MAC address, a mobile or subscriber identifier (such as an International Mobile Subscriber Identity (IMSI)), last CGI, etc. The geographical position is communicated back to the NC, which can then forward the position information to a switch for processing such as for 911 calls.

Title: Microwave drying of coal
Inventor: LEAREY TREVOR R
IPC: C10L9/08
Filed: 2006-11-30
Granted: 2014-07-08
Abstract: A method for drying coal using microwave energy to achieve a controlled aggregate moisture content target range without starting combustion or degrading the coking qualities of the coal.  Coal feed stock is first separated into fine grade coal and one or more larger grades. The fine grade coal is loaded onto a conveyor as a bed of fixed depth. The fine grade coal is conveyed continuously through a microwave-energized heating chamber for drying. The fine grade coal is dried sufficiently so that when it is combined with the larger grade coals, the moisture content of the aggregate is within a target moisture content range. By volumetrically and uniformly heating the coal, the microwave heating chamber boils away the water without heating the coal itself above about 90°C. In this way, the coal does not combust or oxidize, and its coking qualities are retained.
