Title: Method and apparatus for handling and disposal of oil and gas well drill cuttings
Inventor: DIETZEN GARY H
IPC: B63B25/02
Filed: 2000-05-15
Abstract: A method and apparatus for removing drill cuttings from an oil and gas well drilling platform provides for the separation of drill cuttings from at least a volume of the well drilling fluid (i.e. drilling mud) on the drilling platform so that the drilling fluids can be recycled into the well bore. The cuttings are then transferred to a cuttings collection receptacle (eg. trough) on the platform. The separated drill cuttings are then suctioned with a first suction line having an intake portion. The suctioned drill cuttings are transmitted to a processing tank (or multiple such tanks) on the platform, each having a tank interior. A vacuum is formed within the processing tank interior with a blower that is in fluid communication with the tank interior via a second vacuum line. The tank is connected to a floating work boat with a discharge flow line. Cuttings are processed within the tank, being chopped or cut into smaller size particles with a pump that is preferably contained within the processing tank. Cuttings are slurrified or liquefied in the processing tank, then transmitted from the tank to the work boat via the flow line. Multiple holding tanks can be positioned on the drilling platform for storage of cuttings until a work boat arrives. The work boat can be provided with one or more high capacity work boat holding tanks (for example 100-1000 barrels) for receiving cuttings from the multiple holding tanks on the drilling platform when disposal is desired.

Title: Optical fiber connector tuning wrench
Inventor: SANDELS GREGORY A
IPC: B25B13/48
Filed: 2000-07-13
Abstract: A tuning wrench for tuning optical fiber connectors has an enlarged portion from which extends a limiting portion having a diameter greater than the diameter of the opening in the ferrule housing portion of an optical connector. A tubular member protrudes from the limiting portion and has an internal diameter dimensioned to slide over the connector ferrule. The distal end of the tubular member has a pair of tangs adapted to fit within or openings in the front of the flange portion of the ferrule-barrel member of the connector. The distance from the face of the limiting member to the tangs is such that axial pressure on the wrench moves the flange rearwardly out of engagement with its housing but the face of the limiting member butts against the front of the housing before the spring member within the housing bottoms. Rotation of the wrench thus causes rotation of the ferrule-barrel assembly to alter the angular orientation of the eccentricity vector of the ferrule.

Title: Granulates containing feed-enzymes
Inventor: ANDELA CARL SIDONIUS MARIA
IPC: A23K1/00
Filed: 2000-02-10
Abstract: A process for the preparation of an enzyme-containing granulate is disclosed where an aqueous enzyme-containing liquid is mixed with a solid carrier and optionally additive ingredients and is mechanically processed into granules, dried and subsequently coated with polyethylene glycol. The solid carrier preferably essentially consists of an edible carbohydrate polymer. Additive ingredients that could be further incorporated in the formulation of the granules are a gel-forming or slow dissolving compound such as polyvinyl alcohol, water soluble inorganic salts comprising divalent cations and trehalose. This enzyme granulate is suitable for the manufacture of animal feed compositions by mixing feed ingredients with the granulate, treating with steam and pelleting. The compositions show improved enzyme stability during the pelleting process and during storage. At the same time, the dissolution time of the granule is very short so that the bioavailability of the enzyme to the animal is improved.

Title: Double pass folded interleaver/deinterleavers
Inventor: CHANG KOK WAI
IPC: G02B27/28
Filed: 2000-12-15
Abstract: Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. An interleaver/deinterleaver apparatus is described as folded when an optical signal is directed through a single crystal multiple times. Double-pass refers to the optical signal following a (folded) path through the apparatus twice. When operating as an deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., channels). In one embodiment, deinterleaving optical signals separates an optical signal into even and odd International Telecommunications Union (ITU) channels. When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals (e.g., channels) into a multiplexed (e.g., WDM) optical signal. The interleaver/deinterleaver apparatus can be used to increase the bandwidth of an optical network. For example, the interleaver/de-interleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz). In one embodiment, interleaveing combines even and odd ITU channels into a single optical signal.

Inventor: MAMAYEK DON S
IPC: H04R17/00
Filed: 1999-04-30
Abstract: A method of applying a matching layer to a transducer includes placing the transducer on a fixture and covering the transducer with a stencil so that an opening in the stencil allows access to a metal-coated, piezoelectric surface of the transducer, and so that the stencil is affixed to the transducer surface. A roughly cylindrically shaped bead of epoxy is extruded onto the stencil at a predetermined distance from the opening, and a blade is positioned upstanding relative to the transducer surface and located so that the bead lies between the blade and the opening. The fixture is moved laterally so that the blade rolls the bead across the exposed transducer surface to form a layer of epoxy thereon. The fixture can then be moved back in the opposite direction to its initial position if desired. The assembly can also be subjected to a vacuum before the fixture is returned to its initial position. If desired, the fixture can be designed to vibrate during movement. Also if desired, the epoxy bead can initially be placed in a trough designed to decrease surface-area exposure to the air. Alternatively, the fixture can be kept stationary while the blade is moved.

Filed: 2000-03-24
Abstract: An account processing method and system for providing specific pre-authorization parameters for transactions that require specific pre-authorization by a network user specifying conformity parameters within which any requested transaction parameters must comply in order to enable the requested transaction to be approved. Upon establishment of an account, transaction types by standard industrial code (SIC) are specified as needing specific authorization prior to approving the transaction as requested by a merchant. An account issuer provides a service to account members that permits network user to independently specify the parametric conditions under which to approve a transaction within such categories. Once a transaction is approved, the pre-authorization is spent and requires individual pre-authorization of each transaction, thereby minimizing misuse of an account number by merchants or others that come into possession of the network user's account number.
