摘要:
An internal fluid cooling system for a gas turbine aerofoil (2) comprises a plurality of multi-pass cooling arrangements each of which consists of a serpentine passage (50,52,54 & 48,56,58) in the interior of the aerofoil (2). The cooling fluid—in particular air—is supplied to an inlet end (22,24) of each passage (50,52,54 & 48,56,58) and exhausted through a multiplicity of discharge holes (60,62,64,68) to provide tip, leading edge, trailing edge and surface film cooling. The inlet end (22) of a first serpentine passage (50,52,54) is positioned close to the leading edge (26) and flows rearwards while the inlet end (24) of the second serpentine passage (48,56,58) is positioned close to the trailing edge (28) and flows forwards. These serpentine passages are disposed side-by-side, one adjacent the pressure surface (14) and the other adjacent the suction surface (16) on opposite sides of a main load carrying member (30) which comprises a major part of the internal structure (30,36,38,40,42,44) of the aerofoil (2).

A wireless communication device stores a system GUI configuration file and a downloaded service provider GUI configuration file, each of which contains a text name checksum value that is calculated using the text names of the GUI parameter data stored either the system GUI configuration file or the service provider GUI configuration file. The text name checksum values are based on the text names of the GUI parameter data. After the download operation is complete, a text name checksum comparator program compares the downloaded text name checksum value to the initial text name checksum value in the system GUI configuration file. If the two text name checksum values do not match, the downloaded service provider GUI configuration file is rejected.

Multiple-active database systems include at least two database systems that both store a common portion of a relational database. Each database system includes one or more data-storage facilities configured to store data forming the common portion of the relational database in one or more tables and one or more processing modules configured to manage access to the data in the data-storage facilities. One or more management components are configured to distribute database requests directed at the common portion of the relational database among the database systems and to synchronize the data across the database systems when changes are made to the data stored in at least one of the database systems.

The present invention relates to compounds, process for their synthesis, compositions and methods for the treatment and prevention of hepatitis C virus (HCV) infection. In particular, the present invention provides novel compounds, pharmaceutical compositions containing such compounds and methods for using these compounds in the treatment or prevention of HCV infection. The present invention also provides processes and intermediates for the synthesis of these compounds.
摘要:
The invention provides a method for the secondary recovery of oil from an oil-bearing stratum having a zone of high fluid permeability, in which this zone is plugged by introducing into the stratum a gelable solution comprising an alkaline material, a polyphenolic vegetable material such as mimosa tannin extract and formaldehyde, the last compound being present as free formaldehyde, paraformaldehyde, a phenol-formaldehyde resole, hexamethylenetetramine or urea-formaldehyde concentrate. The gelable solution has a pH of at least 9.5 and may optionally include a viscosifier. The gelable solutions are relatively insensitive to brines or temperature and gel to produce mechanically strong gels, even in the presence of oil-wet minerals. If desired, the alkaline material can be an alkali metal carbonate, and the use of such carbonates permits the permeability of the plugged high permeability zone to be adjusted after formation of the gel by treating the gel with acid.
摘要:
An artificial turf remover and infill separator comprising an artificial turf removing station, an infill separating station and an artificial turf collection station. The infill separating station comprises rotatable spinning devices comprises corners, wherein each corner comprises chain links. The artificial turf remover and infill separator is utilized by positioning a strip of artificial turf on an angular ramp, conveying the artificial turf over a first pair of rotatable rollers, conveying the artificial turf between a second pair of rotatable rollers, separating infill from the artificial turf via fin-shaped picks, square-shaped rotatable diggers and the rotatable spinning devices, wherein the chain links jostle the infill material from the artificial turf onto a first and second infill collection conveyor belt. The artificial turf is then conveyed over a first and second base roller, between a rear pair of counter-rotating rollers and then wound around a final artificial turf collection roller.

A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.

A data-synchronization tool is used to ensure synchronization between at least two copies of a relational database that are stored in at least two database systems. The tool includes (a) a sync-control component configured to initiate synchronization of the copies of the database and (b) a sync-execution component configured to replicate one or more changes made to the copy stored in one of the database systems within the copy stored in another of the database systems.
摘要:
The present invention relates to novel polymorphic and amorphous forms of a phosphate salt of 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one, and to processes for their preparation. Such polymorphic forms may be a component of a pharmaceutical composition and may be used to treat a mammalian disease condition mediated by poly(ADP-ribose) polymerase activity including the disease condition such as cancer.
