Title: Tree-mountable hoist support
Inventor: TWILLIGEAR KURT D
IPC: B66D1/28
Filed: 1998-10-26
Abstract: An elongate beam has a mounting end and a projecting end, with a pulley mounted to the projecting end. A length-adjustable belt is mounted to the mounting end of the beam for securing the mounting end of the beam to an upright, such as a tree. A V-shaped brace assembly has a narrow supporting end pivotingly attached to the beam intermediate the beam ends, and a broad base end. The brace assembly includes a pair of legs which form the V-shape. The legs have spaced-apart base ends for positioning adjacent to an upright. A brace plate extends between the base ends of the legs and forms a recess facing away from the supporting end of the brace assembly for receiving uprights of different sizes. A flexible spacing element, such as a chain, extends between the mounting end of the beam and the base end of the brace assembly for limiting the separation between the mounting end of the beam and the base end of the brace assembly.

Title: Oil and gas well cuttings disposal system with continuous vacuum operation for sequentially filling disposal tanks
Inventor: DIETZEN GARY H
IPC: B63B25/02
Filed: 1997-10-14
Abstract: A method and apparatus of removing drill cuttings from an oil and gas well drilling platform includes the steps of separating the drill cuttings from the well drilling fluid on the drilling platform so that the drilling fluids can be recycled into the well bore during drilling operations. The cuttings are then transmitted via gravity flow to a materials trough (11) having an interior defined by sidewalls and a bottom portion. The drill cuttings are suctioned from the bottom portion of the trough interior with a suction line (22) having an intake portion that is positioned at the materials trough bottom.      Drill cuttings are transmitted via the suction line to a pair of hoppers (204, 205) that each have an interior. A vacuum is formed in sequence within the interior of each hopper using a blower (57) that is in fluid communication with the hopper interiors. The two hoppers are positioned one above the other so that cuttings can be added to the first, upper hopper (204) via the suction line and then fed by gravity to the second, lower hopper (205). A valuing arrangement maintains vacuum within the interior of at least one hopper at all times. A conduit discharges from the lower hopper into a selected holding tank so that a number of holding tanks (209, 210) can be filled in sequential, continuous fashion.

Title: Clamshell throttle valve assembly
Inventor: TUNEFF MARK
IPC: F02D9/10
Filed: 1999-03-29
Abstract: A combustion engine throttle valve includes a multipiece clamshell throttle body which is divided along an axis of rotation of a throttling member subassembly, which may be placed within the throttle body as one component. The throttle body further includes a face sealing ledge within the throttle body's air conduit, with the ledge being positioned so that the throttle plate will be in contact with the ledge when the plate is in the closed position, and such that the plate pivots perpendicularly off the ledge when opening. The clamshell design permits greater use of lighter plastics in place of metallic components and minimizes the number of parts through incorporation of plastic injection molding techniques.

Title: Analysis technique, incorporating selectively induced collision dissociation and subtraction of spectra
Inventor: COUSINS LISA
IPC: H01J49/26
Filed: 1999-06-10
Abstract: A method of and apparatus for analyzing a substance takes a stream of ions in said substance and supplies the ions to a collision cell including a quadrupole rod set for guiding the ions and a buffer gas. An RF voltage is applied to the quadrupole rod set to guide ions. An additional alternating current signal is applied to the quadrupole rod set at a frequency selected to cause resonance excitation of the secular frequency of a desired ion, whereby said desired ions are excited and undergo collision with the buffer gas causing fragmentation. The invention then provides modulation of the alternating current signal applied in step (4) whereby periods in which said alternating current signal is applied alternate with periods in which said alternating signal is not applied. The ion spectrum after fragmentation is collected to generate one set of data for one spectrum, representative of the ion spectrum when the alternating current signal is applied, and a another set of data for another spectrum, representative of the ion spectrum when the alternating current signal is not applied. These two spectra can be subtracted to give a spectrum indicative of the effect of fragmentation.

Title: Latent mercaptan stabilizers for improved weatherability of clear halogen-containing polymer compositions
Inventor: NORRIS GENE K
IPC: C08K3/16
Filed: 1999-10-18
Abstract: Stabilizer compositions useful for protecting clear polyvinyl chloride and other clear halogen-containing polymer compositions used in the manufacture of exterior weatherable products against discoloration and degradation caused by exposure to ultraviolet light and weathering in addition to heat comprising a latent mercaptan which degrades during processing of the composition at an elevated temperature to liberate a free mercaptan, in combination with a synergistic amount of a free phenyl salicylate compound. The latent mercaptan may be the sole heat stabilizer additive in the stabilizer composition, but the free mercaptan released during processing may also synergize the activity of organic-based or metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and organotin mercaptides in the polymer composition.      Clear polyvinyl chloride and other clear halogen-containing polymer compositions containing these compounds are also provided which exhibit improved ultraviolet light stability and weatherability without detracting from their thermal performance.
