Inventor: GILLOT LAURENT
IPC: F16L15/04
Filed: 2008-12-22
Abstract: A sealed threaded tubular connection which is resistant to successive pressure loads comprises a male element (1) including a male threading (3) and a female element (2) including a female threading (4) corresponding to the male threading (3). At least one of the elements comprises a lip (5) extending beyond the threading (3) to the free end of the element (6) and the other element comprises a recess (10) for the lip (5). The lip (5) comprises a first zone (7) with a peripheral surface turned towards the other element on which a first sealing surface (13) is disposed which can be radially interference fitted against a corresponding second sealing surface (11) disposed on the peripheral surface of the recess (10) of the other element. The lip (5) has a second axially located zone (8) between said first zone (7) and the free end of the element (6) which comprises a first radial bearing surface (14) turned towards the other element in contact with a corresponding second radial bearing surface (12) disposed on the peripheral surface of the recess (10) of the other element. The first and second zones (7, 8) are axially separated by a third zone (9) with a radial stiffness which is lower than the first and second zones (7, 8). This third zone (9) is capable of being radially deformed towards the other element by a pressure exerted thereon.

Title: Method for operating a thermodynamic circuit, as well as a thermodynamic circuit
Inventor: LENGERT JOERG
IPC: F01K27/00
Filed: 2008-12-03
Abstract: The invention relates to a thermodynamic cycle (1) with at least: -one first heat exchanger (W1) for creating a first heated or partially evaporated working medium flow (15) by heating or partially evaporating a liquid working medium flow (14) by heat transmission from an expanded working medium flow (12); - a second heat exchanger (W2) for creating a second at least partially evaporated working medium flow (18); - a separator (4) for separating a liquid phase (19) from a vaporous phase (10) of the second working medium flow (18); -an expansion device (2) for creating an expanded vaporous phase (10).  According to the invention, pressure pulsations are prevented during the start-up of the cycle in that the vaporous phase (10) separated by the separator (4) is conducted past the expansion device (2) and the first heat exchanger (W1). The liquid phase (19) separated by the separator (4) is cooled in the first heat exchanger (W1) by heat transfer to the liquid working medium flow (14). After the first heat exchanger (W1), the cooled, separated, liquid phase and the separated vaporous phase (10) are brought together.

Filed: 2008-03-07
Abstract: A set of a bolt and a nut having a rotation prohibiting mechanism comprises a foldable part (30) at the tip of a bolt (20), that can be folded around an axis perpendicular to a bolt axis. A tip portion (30) can be folded to either sides with the direction extending along the bolt axis as a center. Grooves (18a-18g) for storing the foldable part (30) are formed on a tip surface (a surface from which the tip of the bolt projects out when the bolt and the nut are tightened) of the nut (12) or the knob (18). A  number of the grooves is an odd number. The grooves are arranged radially with equal angular intervals with a center at a screw hole of the nut. For example, seven grooves are arranged radially with equal angular intervals. In this case, the angle between adjacent two grooves is about 51.4 degrees, and this angle is to be an expected angular resolution of the rotation prohibition. However, according to the above mentioned set of the bolt and the nut, the expected angular resolution can be halved (i.e.  25.7 degrees).

Title: Polyhdroxyalkanoate biopolymer compositions
Inventor: SKRALY FRANK A
IPC: C12R1/19
Filed: 1999-05-21
Abstract: Several novel PHA polymer compositions produced using biological sytems include monomers such as 3-hydroxybutyrate, 3-hydroxypropionate, 2-hydroxybutyrate, 3-hydroxyvalerate, 4- hydroxybutyrate, 4-hydroxyvalerate and 5-hydroxyvalerate. These PHA compositions can readily be extended to incorporate additional monomers including, for example, 3-hydroxyhexanoate, 4-hydroxyhexanoate, 6-hydroxyhexanoate or other longer chain 3--hydroxyacids containing seven or more carbons. This can be accomplished by taking natural PHA producers and mutating through chemical or transposon mutagenesis to delete or inactivate genes encoding undesirable activities. Alternatively, the strains can be genetically engineered to express only those enzymes required for the production of the desired polymer composition.; Methods for genetically engineering PHA producing microbes are widely known in the art (Huisman and Madison, 1998, Microbiology and Molecular Biology Reviews, 63: 21-53). These polymers have a variety of uses in medical, industrial and other commercial areas.

Title: Method and apparatus for using uplink control information for inter-cell decoding and interference cancellation
Inventor: PALANKI RAVI
IPC: H04W72/08
Filed: 2009-07-10
Abstract: Techniques for supporting data transmission on the uplink in a wireless network are described. In an aspect, a user equipment (UE) may send a data transmission to a serving base station and may send uplink control information (UCI) to a non-serving base station. The UCI may include pertinent information to allow the non-serving base station to process the data transmission from the UE. In one design, the UCI may allow the non-serving base station to estimate the interference due to the data transmission from the UE and to cancel the interference at the non-serving base station. The interference cancellation may improve the received signal quality at the non-serving base station. After the interference cancellation, the non-serving base station may process a data transmission from another UE served by the base station.

Abstract: A method and apparatus for transporting a pipeline pig provides a housing having an interior. A jacking mechanism is contained within the housing interior. A carriage is supported by the jacking mechanism for movement between an upper extended and a lower retracted position. The carriage has a concave surface that generally cradles a pipeline pig to be transported.  A pulling device on the housing enables a pipeline pig to be pulled from a location that is not on the carriage to a position that is on the carriage. The position that is not on the carriage can be for example a pig trap. As part of the method of the present invention, the pulling device pulls the pig from the pig trap or other location to the carriage and then the carriage is retracted into the housing for transport to a remote location.
