Title: Block- and band-oriented traversal in three-dimensional triangle rendering
Inventor: ZHAO RANDY X
IPC: G06T15/00
Filed: 1998-06-18
Abstract: A system and method for traversing and rendering a graphic primitive represented in screen space, employing block- and band-oriented traversal algorithms (1208, 1203) in texture mapping. Improved performance is achieved through burst-mode texture access and texture caching in connection with a texture map subdivided into squares. Block- and band-oriented traversal facilitates minimization of page breaks and texture cache swap-out. Improved determinism is facilitated by obviating the need for pixel sorting algorithms (1201). Improved re-use of retrieved data segments (1202) in burst-mode access is facilitated.

Title: Row cleaner suspension
Inventor: STEPHENS LYLE EUGENE
IPC: A01C7/20
Filed: 2000-02-01
Abstract: A row cleaner device for a furrow forming row unit includes a support arrangement with a parallel linkage having a single acting hydraulic cylinder connected between upper and lower links. The cylinder extension is controlled by a hydraulic circuit to provide adjustable down pressure to maintain consistent operation of the cleaner devices in varying ground conditions. A tensioning device such as a spring extending generally parallel to the cylinder acts to retract the cylinder. A blocking valve can be closed to maintain the cleaner device in the raised position and can lock the cylinder in any desired extended position. An energy storage device such as a spring compressed between the cylinder and one of the links permits limited vertical movement of the linkage without change of cylinder extension to protect the device and accommodate obstacles and ground surface irregularities in the path when the cylinder is locked in position. The cylinder can be controlled as a function of the position of the opener, and, can be controlled to raise the cleaner device automatically with raising of the row units. The row cleaner can be supported in various positions and can be controlled remotely. The cleaner can be conveniently raised to the non-operating position to avoid undesirable ground contact.

Title: Gas bolt heater
Inventor: TATARCZUK GEORGE
IPC: F23D14/38
Filed: 2000-04-12
Abstract: A gas bolt heater for loosening large bolts and studs has a hollow cylindrical housing defining a cylindrical heating chamber within the housing. A heating tube projecting from one end of the housing has a longitudinal bore. A first cylindrical insert closing the lower end of the chamber has a through opening communicating with the bore of the heating tube, and a second cylindrical insert located within an opposite end of the cylindrical housing has an elongate passage extending axially of the cylindrical housing. Downwardly convergent air passages in the second cylindrical insert have mouths distributed around the elongate passage, at a lower end of the passage, and an air supply duct communicates through the cylindrical housing with the air outlet passages. In use, air jets discharge from the mouths of the air outlet passages around an outlet end of a tip of an oxy-acetylene torch inserted through the elongate passage so that the flame of the oxy-acetylene torch is directed longitudinally of the cylindrical heating chamber and does not impinge directly on the wall of housing. The useful life of the gas bolt heater is thereby substantially extended.

Title: Very low sulfur gas feeds for sulfur sensitive syngas and hydrocarbon synthesis processes
Inventor: TAYLOR JAMES HOWARD JR
IPC: B01D53/81
Filed: 1999-01-15
Abstract: Very low sulfur content hydrocarbon gas is achieved by sequentially contacting the gas first with zinc oxide and then with nickel metal. This has reduced the total sulfur content of natural gas feed for a fluid bed syngas generator to less than 0.1 ppm and has resulted in greater syngas productivity. A zinc oxide guard bed downstream of the syngas generator reduces the total sulfur content of the syngas to less than 10 vppb and preferably less that 5 vppb. This very low sulfur content syngas is used for sulfur sensitive processes, such as hydrocarbon synthesis. The process is especially useful for natural gas which contains H2S, COS, mercaptans and other sulfur bearing compounds.

Title: Tensioning and absorbing element
Inventor: EBERT SIEGFRIED
IPC: B62M9/16
Filed: 1999-02-25
Abstract: The invention relates to a tensioning and absorbing element for chain drives which comprises an elastically deformable ring part and a toothed ring arranged on the circumference thereof. The ring part is designed such that it is circular when in a non-tensioned and non-mounted state, and takes on an elliptical shape when between a loose side and tight side of the chain drive. The toothed ring engages with the loose side and the tight side and transmits a tension force generated by the elliptical deformation of the ring part on both the loose and tight sides. According to the invention, the ring part is designed so that the cross-section profile steadily changes with increasing deformation of the ring part in such a way that the ratio between the height of the cross-section profile and the width of the cross-section profile is approximately 4 % smaller when the ring part is in a maximally pretensioned state than when the ring part is in a tension-free state.

Inventor: NEWELL TERRY E
IPC: H04L25/08
Filed: 1999-04-01
Abstract: A bus for high signal quality interconnections, comprising means for producing at least one common mode reflection, often for differential transmission line interconnections. Also, a bus for high signal quality interconnections further comprising means for under-damping the signal and/or reducing the common mode noise. In both cases the means are at least one impedance termination. To produce common mode reflections, there are non-contact couplers terminated by short and open circuits, which cause the reflections from via connectors and other like impedance discontinuities to be re-reflected in common mode so that they are rejected by a differential receiver. To produce under-damping of the signal and/or a reduction of the common mode noise, capacitive terminations are used. The under-damping of the signal sharpens in the falling edge of the coupler pulses.
