| 20100000158 | POLYCRYSTALLINE DIAMOND ABRASIVE COMPACTS - This invention is for a polycrystalline diamond composite material comprising diamond particles and a binder phase, the polycrystalline diamond composite material defining a plurality of interstices and the binder phase being distributed in the interstices to form binder pools. The invention is characterised in that there is present in the binder phase a separate tungsten carbide particulate phase in excess of 0.05 total volume %, but not greater than 2 volume %, expressed as a % of the total composite material and that the tungsten carbide particulate phase is homogenously distributed in the composite material in such a manner that the relative standard deviation of the tungsten carbide grain size is less than 1. The invention extends to a method of manufacturing the composite material and to a polycrystalline diamond abrasive compact comprising the diamond composite material for use in cutting or abrading of a substrate or in drilling applications. | 01-07-2010 |
| 20100064595 | POLYCRYSTALLINE DIAMOND ABRASIVE COMPACTS - The invention is for a polycrystalline diamond abrasive compact comprising a layer of polycrystalline diamond bonded to a cemented tungsten carbide substrate. The polycrystalline diamond defines a plurality of interstices and a binder phase is distributed in the interstices to form binder pools. The polycrystalline diamond is characterised by the presence of a separate tungsten particulate phase in the binder phase, in excess of 0.05 volume % but not greater than 2 volume %, expressed as a % of the total polycrystalline diamond, and the binder phase further containing a low eta-phase, Co3W3C, content as determined by conventional XRD analysis, an XRD peak height of the <511 > eta-phase (Co3W3C) peak which is less than 0.06 when expressed as a fraction of the peak height of the <200> cubic cobalt peak. The invention extends to a composition and to a method for manufacturing the polycrystalline diamond abrasive compact. | 03-18-2010 |

| 20110226532 | INSERT FOR AN ATTACK TOOL, METHOD FOR MAKING SAME AND TOOLS INCORPORATING SAME - The invention relates to an insert for an attack tool, the insert comprising a super-hard cap having a volume and bonded to a substrate at an interface, the super-hard cap having an average Young's modulus of greater than 900 GPa and the substrate characterised in that it comprises a reinforcing bolster portion as a means for stiffening a region of the substrate proximate the interface, the reinforcing bolster portion having an aggregate volume that is greater than that of the super-hard cap and an average Young's modulus at least 60% that of the super-hard cap. The invention further relates to a method for manufacturing such an insert and a method for using such an insert. | 09-22-2011 |
| 20110274885 | ABRASIVE INSERTS - The invention relates to an abrasive insert comprising a layer of PCD or PCBN; and a cemented carbide substrate to which the layer of PCD or PCBN is bonded through an interlayer; the interlayer comprising a bonded mass of superhard abrasive particles and refractory particles wherein an average size of the superhard abrasive particles is the same as or less than that of the refractory particles and to a method of manufacture of the insert. | 11-10-2011 |

| 20100106361 | INTEGRATED BATTERY SERVICE SYSTEM - An integrated battery service system performs a plurality of services related to a battery, such as battery testing, battery charging, and the like. In addition, the integrated service system provides services to devices/components that are coupled to the battery, such as starters, alternators, etc. The integrated battery service system allows a user to abort a service and then resume the process from where the process was aborted. When conducting a service, the integrated battery service system determines a noise level caused by devices/components coupled to the battery. The integrated battery service system includes connectors configured to couple to a battery for receiving input signals, a processor coupled to the connectors, and a memory device coupled to the processor for storing control codes and operation history. The control codes, when executed by the processor, control the system to selectively abort a service in response to a user input. Since the memory stores operation histories, the processor may access the memory to retrieve data related to the aborted service and parameters obtained during the service before the process was aborted. The system reinstates the aborted service in response to another user input. | 04-29-2010 |

| 20100000953 | MODULAR BLOCKING PANEL SYSTEMS FOR RACKS AND CABINETS - The disclosure generally relates to a modular blocking panel system for a rack. The modular blocking panel system consists of multiple standardized panels which snap-together, or slidably attach to one another, in order to fill openings of any size in a rack. The panels connect to one another so that there is a seal at the junction between the panels. The seal blocks hot air in the interior of the rack from seeping through the panels and mixing with the cold air supply on the exterior of the panels. Multiple panels can be combined to create a single modular panel to cover any sized opening. | 01-07-2010 |

| 20120084304 | HIGH EFFICIENCY BINARY ENCODING - A method and a system are provided for encoding and processing digital information. The digital information is encoded according to binary encoding formats corresponding to primitive data types. The primitive data types comprise scalar data types including Boolean, integer, float, decimal, time stamp, string, symbol, binary large object, and character large object data types. The primitive data types also comprise composite data types including structure, list, and S-expression data types. The binary-encoded digital information is stored in a message with a predetermined format for transmission. No metadata is included in the message. | 04-05-2012 |
