| Number | Title | Issue Date |
| 6357540 | Rotary drill bit with lip seal in roller cone bit A roller-cone drill bit in which a double lip seal, made of a self-lubricating elastomer, protects the bearings from the mud.... | 03/19/2002 |
| 6311789 | Bit breakers, bits, systems, and methods with improved makeup/breakout engagement A bit breaker is formed of a U-shaped base and latchable gate which closes the U. When the gate is in a closed position, evenly spaced chocks on both the base and gate protrude into the central cavity of the bit breaker to engage slots formed in the bit. ... | 11/06/2001 |
| 6298762 | Saw blade with inserted multi-tooth arcs Solid carbide segments are brazed to the rim of a steel body and then teeth are ground into them. This allows more teeth/inch on the perimeter and larger diameter blades than on previous carbide-tipped blades. The segments, which typically form an arc of ... | 10/09/2001 |
| 6290006 | Apparatus and method for a roller bit using collimated jets sweeping separate bottom-hole tracks A roller cone jet-type drill bit with nozzles which direct collimated streams of mud at different angles, to sweep different radii of the hole bottom.... | 09/18/2001 |
| 6289636 | Easy parking meter post replacement without excavating the street or sidewalk Replacement of a damaged post for a parking meter can be accomplished by cutting the post off near the ground and affixing a replacement post to the stub of the original post with a retaining device which grips the two portions of the post from inside the... | 09/18/2001 |
| 6285373 | Method and apparatus for texture transmission and storage A system and method for computer graphics generation which uses a local library of graphics textures. When an application, run either locally or over a communications system, requires texture-mapped graphics, texture data is retrieved from the local libra... | 09/04/2001 |
| 6279671 | Roller cone bit with improved seal gland design In the seal gland in a rotating cone drill bit, the O-ring is initially compressed between the journal and a central portion of the gland which has a cross-section parallel to the journal. These two concentric surfaces provide a minimum amount of contact ... | 08/28/2001 |
| 6278645 | High speed video frame buffer A device for storing pixel information for displaying a graphics image on a display includes a frame buffer and a processor. The information includes an intensity value and a value associated with each of a plurality of additional planes for each pixel. T... | 08/21/2001 |
| 6260635 | Rotary cone drill bit with enhanced journal bushing The present invention allows the load carrying capability of a drill bit journal bearing or bushing to be increased. The present invention increases the length of the journal bushing by using the ball bearings to retain the journal bushing at a desired lo... | 07/17/2001 |
| 6253261 | System and method for direct memory access in a computer system A system and method for improving the efficiency of DMA transfers. In particular, a "continue" command is provided for DMA block transfers. In practice, this command allows the system to begin a DMA transfer before the entire size of the transfer block is... | 06/26/2001 |
| 6227316 | Jet bit with variable orifice nozzle A nozzle for a drill bit has an adjustable orifice, allowing a single nozzle to change the pressure drop for a given flow rate. This is accomplished by the use of two plates, each having a shaped aperture therein. The degree to which the two apertures are... | 05/08/2001 |
| 6220374 | Rotary cone drill bit with enhanced thrust bearing flange The present invention allows the load-bearing capabilities of a drill bit thrust flange to be increased. The invention utilizes a thrust flange that is larger than the inside diameter of an associated drill bit journal bushing. The thrust flange may exten... | 04/24/2001 |
| 6213225 | Force-balanced roller-cone bits, systems, drilling methods, and design methods Roller cone drilling wherein the bit optimization process equalizes the downforce (axial force) for the cones (as nearly as possible, subject to other design constraints). Bit performance is significantly enhanced by equalizing downforce.... | 04/10/2001 |
| 6206116 | Rotary cone drill bit with machined cutting structure A rotary cone drill bit is provided with at least one cutter cone assembly having a machined cutting structure which will maintain an effective cutting profile despite abrasion, erosion and/or wear of the associated cutting elements. The machined cutting ... | 03/27/2001 |
| 6188410 | System for processing vertices from a graphics request stream An apparatus for processing a graphics request stream begins processing subsequent vertex data while processing previous vertex data. To that end, the apparatus has a vertex assembler having an input for receiving graphics requests, and a processor (coupl... | 02/13/2001 |
| 6184666 | Buck converter with parallel switches A converter for reducing the amplitude of a DC input signal includes first and second switches that each are coupled between an input port for receiving the input signal, and voltage reducing circuitry for reducing the amplitude of the input signal. The t... | 02/06/2001 |
| 6181355 | Graphics processing with transcendental function generator A graphics processor for processing vertices of a polygon includes an input for receiving an instruction for processing a given vertex, memory for storing a first lookup table and a second lookup table, and an interpolation engine that, responsive to rece... | 01/30/2001 |
| 6170583 | Inserts and compacts having coated or encrusted cubic boron nitride particles An insert is provided for a rock bit for drilling bore holes in the ground and other downhole tools. The cutting portion of the inserts consist of encrusted cubic boron nitride pellets, tungsten carbide particles and a binder material which are fused toge... | 01/09/2001 |
| 6154223 | Integrated graphics subsystem with message-passing architecture A graphics processing chip which uses a deep pipeline of multiple asynchronous units to achieve a high net throughput in 3D rendering. Preferably reads and writes to a local buffer are provided by separate stages of the pipeline. Preferably some of the in... | 11/28/2000 |
