Title: Stable protein and nucleic acid formulations using non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity
Inventor: KNEPP VICTORIA M
IPC: A61K38/48
Filed: 1997-10-15
Abstract: This invention relates to stable non-aqueous formulations which are suspensions of proteinaceous substances or nucleic acids in non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity. More specifically, the present invention relates to stable protein or nucleic acid formulations wherein the compound remains in stable, dry powder form, yet the formulation is flowable and, therefore amenable to delivery to an animal via injection, transdermal administration, oral delivery or using an implantable device for sustained delivery. These stable formulations may be stored at elevated temperatures (e.g., 37 °C) for long periods of time and are especially useful as flowable formulations which can be shipped and/or stored at high temperatures or in implantable delivery devices for long term delivery (e.g., 1-12 months or longer) of drug.

Abstract: Techniques for detecting moving video objects in a compressed digital bitstream (111) and for tools for editing compressed video are disclosed.  Video objects (117) are detected and indexed by analyzing a compressed bitstream to locate scene cuts (112), estimating operating parameters for a camera which initially viewed the video (114), and detecting one or more moving video objects represented in the compressed bitstream by applying global motion compensation which account for the estimated operating parameters. Tools are provided for permitting dissolve, masking, freeze frame, slow and variable speed playback, and strobe motion special effects to compressed video. The tools may be implemented in a system for editing (130) compressed video information over a distributed network.
Patent CA-2291841-A1 (CA)
Inventor: FOERG WOLFGANG
IPC: F25J1/02
Filed: 1998-05-27
Abstract: The invention relates to a process for liquefying a hydrocarbon-rich stream, in particular a natural gas stream, by indirect heat exchange with the refrigerant mixture of a refrigerant mixture cycle, the refrigerant mixture being compressed in two stages or multiple stages and where the refrigerant mixture is fractionated into at least one lower-boiling refrigerant mixture fraction and into at least one higher-boiling refrigerant mixture fraction.   According to the invention, the compressed refrigerant mixture (23) is at least partially condensed (E4) downstream of the penultimate compressor stage and is fractionated (D4) into a higher-boiling liquid fraction (26) and a lower-boiling gas fraction (24). The lower--boiling gas fraction (24) is compressed to the final pressure, partially condensed (E5) and fractionated (D5) into a lower-boiling gas fraction (10) and a higher-boiling liquid fraction (27). The higher-boiling liquid fraction (27) is added to the partially condensed refrigerant mixture stream (23), and the gas fraction (10) forms the lower-boiling refrigerant mixture fraction and the liquid fraction (26) forms the higher-boiling refrigerant mixture fraction of the refrigerant mixture cycle. Alternatively to this, the compressed refrigerant mixture (20, 31, 34) can be partially condensed (E3, E4, E5) after each compressor stage and fractionated in each case into a lower--boiling gas fraction (21, 32, 10) and a higher-boiling liquid fraction (30, 33, 35). Only the gas fraction (21, 32) from the partial condensation (E3, E4) in each case is further compressed and the liquid fractions 33, 35) from the second fractionation (D4, D5) on are added to the partially condensed stream (20) from the first compressor stage upstream of its fractionation (D3).     Again, the gas fraction (10) from the final fractionation (D5) forms the lower-boiling refrigerant mixture fraction and the liquid fraction (30) from the first fractionation (D3) forms the higher-boiling refrigerant mixture fraction of the refrigerant mixture cycle.

Title: Locking telescoping joint for use in a conduit connected to a wellhead
Inventor: HAYNES MICHAEL JONATHON
IPC: E21B17/06
Filed: 2000-01-17
Abstract: A locking telescoping joint is for use in a conduit connected to a wellhead, which permits the conduit to be axially displaced to a new position in the well bore without disconnecting the conduit from the wellhead, and secured in the new position. The locking telescoping joint includes two telescopically interconnected tubular sections which are relatively movable between a fully retracted and a fully extended position and can be locked in a desired position. In contrast with telescoping joints without the locking function which is useful to axially display downhole tools attached to the bottom end of the conduit. The locking telescoping joint enables the use of the telescoping joint to be extended into new applications, such as placing and maintaining a tubing string in tension or compression. The use of the locking telescoping joint reduces the time and cost of many well completion and maintenance operations and thereby reduces the cost of producing hydrocarbons.

Filed: 2000-05-05
Abstract: A unique, inexpensive and easily manufactured check valve device features a valve housing, a valve seat, a resilient ring seal, a retaining sleeve, a valve member and a valve spring. The valve housing defines an inlet channel, an outlet channel and at least one valve bore through which the inlet and outlet channels interconnect. Formed in the valve bore is the valve seat. The valve seat has a generally flat annular surface from within which an opening emerges into a preferred one of the two channels. The resilient ring seal is situated atop, and is coaxial with the opening defined by, the flat annular surface of the valve seat. Situated within the valve bore, the retaining sleeve serves to retain the resilient ring seal by its periphery against the flat annular surface of the valve seat. The valve member is moveable within the retaining sleeve. By its head portion at one end, the valve member is adapted to be pressed against, and form a leak-proof seal with, the resilient ring seal. Compressively disposed within the valve bore against a non-seat facing side of the valve member, the valve spring compels the head portion of the valve member against the resilient ring seal. The check valve device is thus normally biased in a closed position wherein the preferred channel is cut-off from the valve bore of the valve housing.
