  • Patent number: 6711294
    Abstract: Data is received from a memory, which includes bitmap images, for output on an output device. The images may be stored in compressed or uncompressed form. The operating system, application or generic graphics environment program interface, queries the printer driver for the types of image compression formats supported by the printer. If the image is available in a compatible compressed format, that compressed image is read from memory. Alternatively or in addition, the best possible compression format supported by the printer is selected from the formats available in the printer driver. The image is then loaded in a printer compatible compression format or compressed using the selected format. The image is spooled in the selected compression format. The image file may be spooled as a raw file or metafile depending on the embodiment used.

  • Patent number: 6633906
    Abstract: A method and system for managing Windows desktops in a heterogeneous server environment is provided. A Windows User Profile is generated for a user and associatively stored with desktop information in a datastore on a heterogeneous server. The heterogeneous server may be a non-Windows-based server. The desktop information provides configurability of a desktop of a Windows-based data processing system. The desktop may be a restricted desktop that may be either non-modifiable or only temporarily modifiable by the user for a session on the Windows-based data processing system. The datastore may contain a pair of desktops for a user, in which one of the pair of desktops is a Windows NT desktop and one of the pair of desktops is a Windows 95 desktop or a Windows 98 desktop.

  • Patent number: 6628291
    Abstract: A frame buffer system includes a first frame buffer containing a first set of pixels, and a second frame buffer containing a second set of pixels. A first register is connected to an output of the first frame buffer, wherein the first register a number of pixels is stored in which a group of bytes of data is stored for each of the number of pixels. A second register is connected to an output of the second frame buffer, wherein the second register a number of pixels is stored in which a group of bytes of data is stored for each of the number of pixels. A selection logic is connected to the first frame buffer and to the second frame buffer. The selection logic selectively selects pixels to be read from the first frame buffer and the second frame buffer into the first register and the second register. A multiplexer has a first input connected to an output of the first register, a second input connected to an output of the second register, and an output configured for connection to a digital to analog converter.

  • Patent number: 6311789
    Abstract: 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. The bit breaker is designed to be used with either roller cone bits or drag bits.

  • Patent number: 6298762
    Abstract: 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 a circle, provide the improved performance of carbide blades without excessive expense of solid carbide blades.

  • Patent number: 6289636
    Abstract: 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 post. The retaining device is only reachable through the post when the meter head is removed, thus preserving the integrity of the post from vandals.

  • Patent number: 6279671
    Abstract: 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 pressure for a given amount of squeeze than other configurations. Chamfers connect the central portion to the sidewalls of the gland, so that after the seal has worn in use, it will ride up onto the chamfers, where additional squeeze to the seal. This allows the seal to operate in a standard regime during the first part of its lifetime and to automatically shift to a more compressed mode as the seal wears.

  • Patent number: 6278645
    Abstract: 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. The frame buffer memory has a series of consecutive addresses for storing information to be output to the display. The frame buffer may be subdivided into a plurality of blocks, where each block corresponds to a region of the display having a plurality of contiguous pixels. The processor places the pixel information within the frame buffer memory so that in a given block there are placed at a first collection of consecutive addresses the intensity values for each of the pixels in the block.

  • Patent number: 6260635
    Abstract: 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 location between the journal and the cutter cone assembly. Normally, the journal bushing is retained by a flange formed on the interior surface of the cutter cone assembly. In the present invention, this flange is removed, and the ball bearings are used as a retention device for the journal bushing. With the flange removed, the length of the journal bushing may be increased.

  • Patent number: 6253261
    Abstract: 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 known and to continue the transfer, avoiding an additional setup time, by simply instructing the DMAC to continue sending data in the same manner. Transfer continuation is accomplished by resetting the DMA transfer count register to a new value without ever stopping the transfer. Each time the transfer count runs down, the system resets it to a higher value and continues the transfer rather than initializing a second transfer.

  • Patent number: 6227316
    Abstract: 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 overlapped determines the size of the orifice. The movement of the apertures, and thus the size of the orifice, can be adjusted at the drilling site.

  • Patent number: 6220374
    Abstract: 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 extend past the inside diameter of the journal bushing up to a distance equal to two times the thickness of the journal bushing. The invention may also utilize a thrust washer that is disposed adjacent the thrust flange to assist in bearing loads applied to the thrust flange.

  • Patent number: 6206116
    Abstract: 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 structure may be formed on a generally cone shaped blank by a series of lathe turns and/or plunge cuts. The cutting elements may be formed with an aggressive cutting profile. For one application, the crest of each cutting element has the general configuration of an ogee curve. A layer of hardfacing material may be applied over all or selected portions of the machined cutting structure.
