Patent CA-2474410-A1 (CA)
Inventor: BUTLER BRYAN VIRGE
IPC: F04B47/04
Filed: 2004-07-15
Abstract: The present invention provides a hydraulically driven multiphase pump system and methods for pumping a fluidstream from the surface of a well. The hydraulically driven multiphase pump system consists of two vertically disposed plungers. The plungers are hydraulically controlled and actuated to work in alternate directions during a cycle using a closed loop hydraulic system. Each cycle is automatically re-indexed to assure volumetric balance in the circuits. An indexing circuit ensures that each plunger reaches its full extended position prior to the other plunger reaching its preset retracted position. A power saving circuit is used to transfer energy from the extending plunger to the retracting plunger. A trim circuit is used to ensure a proper fluid level in the indexing circuit and the power saving circuit. Additionally, a rapid reversal circuit may be employed to increase the rate of the two vertically disposed plungers.

Title: Device, record carrier and method for recording information
Inventor: WEIJENBERGH PAULUS G P
IPC: G11B27/19
Filed: 2003-02-07
Abstract: A device, record carrier (11) and method for recording information on a track (9) of the record carrier (11) is described. The record carrier (11) contains a disc information area with information about the record carrier (11), such as for example a write strategy for that record carrier (11). The device has disc information reading means (35) for reading the disc information area. The disc information area further contains extended information blocks. The extended information block have a block version number and additional parameters. The block version number defines how the additional parameters are to be interpreted. In this manner a more flexible backwards compatibility system is realized. Drives which are able to interpret the additional parameters of an extended information block can chose to use the additional parameters in that block. Older drives use other blocks or fall back to the first basic part of the disc information area.

Abstract: The subject invention relates to a low cost method of producing peptides, including antimicrobial peptides (AMPs), by using microbes. The subject methods enable greatly improved yields of the peptide/AMP as compared to tho se heretofore known in the art. The subject methods also surprisingly enable th e use of Pseudomonas fluorescens to produce AMPs and other peptides. There are several components of the subject invention, which can be used alone or in combination. The subject invention provides for the production of peptides/AMPs in concatemeric precursors. The subject invention also provide s novel methods of assembling monomers into multimers, and of cleaving the multimers to yield active monomers. The subject invention also relates to th e use of these multimers fused to carrier peptides to produce fusion proteins. Preferably, both the multimers and the fusion proteins (multimers with the carrier polypeptides) lack charge balancing. It has been surprisingly determined that it is not necessary to offset the positive charges of multip le copies of AMPs in multimeric constructs. Thus, the subject invention enables the use of a wider range of multimers and carrier peptides.

Abstract: The present invention generally provides apparatus and methods for reducing the pressure of a circulating fluid in a wellbore. In one aspect of the invention an ECD (equivalent circulation density) reduction tool provides a means for drilling extended reach deep (ERD) wells with heavyweight drilling fluids by minimizing the effect of friction head on bottomhole pressure so that circulating density of the fluid is close to its actual density. With an ECD reduction tool located in the upper section of the well, the friction head is substantially reduced, which substantially reduces chances of fracturing a formation.
