Title: Process for producing metal powders
Inventor: STEFAN RINALDO A
IPC: B22F9/28
Filed: 2005-04-18
Abstract: A process for the production of extra fine spherical metal powders by chemical vapor deposition and dissolution techniques, including metal carbonyls, wherein the metal containing process gas is propelled upwardly through a heated reactor. By employing an upward gas flow as opposed to the conventional downward gas flow, a closer approximation of theoretical plug-flow velocity profiles are achieved thusly resulting in a desirably narrower size particle distribution obviating or reducing the need for subsequent classification techniques.

Patent CA-2593624-A1 (CA)
Inventor: CHENG HUNG YU
IPC: B42F3/04
Filed: 2005-01-24
Abstract: A ring binder mechanism that retains loose-leaf pages and has ring members that do not snap together when they close and that easily open and close as pages accumulate. The mechanism includes a housing that supports two hinge plates for loose pivoting motion, moving the ring members apart or together. The mechanism further includes an actuating lever pivotally mounted on the housing. The lever moves a travel bar and locking elements for controllably pivoting the hinge plates, and therefore controllably moving the ring members apart and together. In particular, the locking elements cam the hinge plates to softly close the ring members. When the ring members are apart, the locking elements register with openings in at least one of the hinge plates. When the ring members are together, the locking elements are out of registration with the openings, blocking the hinge plates from pivoting to separate the ring members.

Abstract: A self-tightening device for fastening two structures together includes a female component and a male component where the female component is capable of receiving the male component. The female component includes a moveable member, an energy storing mechanism and a retaining mechanism. The movable member is movable between an unlocked position and a locked position. The energy storing mechanism has stored energy for causing the moveable member to move from the unlocked to locked position when the energy in the energy-storing mechanism is released. The retaining mechanism holds the energy-storing mechanism in the stored-energy state until the retaining mechanism is released. Upon the release of the retaining mechanism, the energy storing mechanism is actuated from the stored-energy state to the released-energy state causing the movable member to move from the unlocked position to the locked position engaging the male component with the female component when the male component is inserted within the female component.

Abstract: The present invention is directed to methods for controlling the operations of a well service rig at a well site by evaluating load sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and an average rig load can be determined for each pull of tubing or rods from a well. The average rig load can be used to calculate and set a rig overload level. If the rig load sensor reads a rig load at or above the rig overload level, the clutch for the hoist can be disengaged and the brake applied to prevent the load from either damaging the rig or breaking off the tubing or rods in the well. In addition, the rig load can be evaluated to determine when the limit the block speed when pulling rods or tubing.
