Abstract: A method and a system for testing a borehole in an underground formation by the use of so-called closed chamber testing. When carrying out the method, a test or production pipe (5) is carried down the borehole, where the test pipe can be closed at its upper end and at its lower end is provided with a downhole assembly (6) comprising equipment for testing of fluid flow from the formation (3), the annulus (23) between the test pipe (5) and a casing (20) in the borehole being shut off during the test by a gasket (22) at a desired depth, and fluid from the formation being allowed to flow through the test pipe (5) to a collecting tank (9) coupled to the test pipe via a flow head (4) at the upper end of the test pipe (5). In the downholeassembly (6) at the lower end of the test pipe (5) there is releasably retained a pig (30) forming a barrier between formation fluid and a lightweight damping fluid (7) filling the test pipe above the pig, the pig (30) being released at the start of the test and being moved in a controlled manner upwards in the pipe (5) as a result of a positive pressure difference between the fluids below and above the pig.

IPC: C12N15/62
Filed: 2000-05-03
Abstract: The present invention provides bacterial strains for secretion of soluble biologically active recombinant heterologous proteins into periplasm or on a  surface/into a cultivation medium of bacteria. The invention exploits the secretion system of Gram-negative bacteria including periplasmic chaperones and usher/secretin proteins. For accomplishing the aim, the bacterial strain s simultaneously express the fusion protein (signal peptide)-(mature heterologous protein)-(subunit of a bacterial surface structure, Caf1), periplasmic chaperone specific for the subunit, and outer membrane usher/secretin protein specific for the subunit. Secretion of fusion protein s: (signal peptide of Caf1)-(mature human IL-1.beta.)-(mature Caf1), (signal peptide of Caf1)-(mature human GM-CSF)-(mature Caf1), and (signal peptide of  Caf1)-(mature human IL-1ra)-(mature Caf1) that were expressed in Escherichia  coli simultaneously with the periplasmic chaperone CaflM and the usher/secretin protein CaflA are examples of the use of the invention.</SDOA B>

Abstract: A four-wheeled handcart used to transport a load under the control of an operator. The four-wheeled handcart is comprised of two main assemblies. The first assembly carries the load and the second assembly supports the load. The load is secured to the carrying assembly which is then tilted rearwards by the operator, using handles extending from the carrying assembly, until the carrying assembly is engaged by the supporting assembly. In this configuration the two assemblies are positively engaged to become an integrated unit which carries and supports the load thus enabling the operator to function solely as the pilot for the handcart.

Patent CA-2381549-A1 (CA)
Title: Sucker rod tool
Inventor: NEWMAN FREDERIC M
IPC: E21B19/16
Filed: 2002-04-12
Abstract: Tongs for assembling sucker rods of oil wells include a switch that senses movement of the tong's backup wrench relative to the tong's housing. When screwing two sucker rods into a threaded coupling, an upper jaw of the tongs rotates an upper sucker rod relative to a lower sucker rod, while the backup wrench holds the lower rod relatively stationary. When the tongs apply a torque that indicates that the threaded connection is beyond hand tight (i.e., at the shoulder point), a torque reaction force kicks the backup wrench to a position that trips the switch. A control responsive to the switch and a rotation sensor monitors and/or controls the threaded connection's circumferential displacement past the shoulder point. By sensing the position of the backup wrench directly, the switch can consistently identify the shoulder point independent of the tong's hydraulic pressure, thus avoiding oil viscosity related errors.

Title: Modulator processing for a parametric speaker system
Inventor: SPENCER MICHAEL E
IPC: H04R3/00
Filed: 2000-08-25
Abstract: A parametric loudspeaker system using improved modulators to compensate for the non-linearity of the parametric process in air (NLD) when driving the ai r at saturation levels and below saturation levels. The parametric loudspeaker  uses a preprocessed (Nth order distortion compensator) single sideband (SSB)  modulator that offers ideal linearity as characterized by square root pre- processed double sideband modulators but with a lower carrier frequency and without the wide bandwidth requirements. By eliminating some or all of the lower sideband the carrier frequency can be reduced without producing sideba nd frequencies in the audible range. Lower operational frequencies result in greater translation efficiency and greater output capability before reaching  the saturation limit of air. A preprocessor minimizes the effects of saturation limits for double sideband, truncated double sideband or single sideband processing to achieve superior output.

Patent CA-2390818-A1 (CA)
Title: Marine propulsion system
Inventor: MARK THEODORE
IPC: B63H20/14
Filed: 1998-07-17
Abstract: In prior stern drive marine propulsion systems, power is transmitted through an arrangement of clutches, bevel gears and shafts to the propeller located below the water surface. This restricts the amount of torque which can be transmitted particularly for large commercial boats. The present invention therefore provides an outdrive designed to surpass the horsepower and torque limitations set by current state-of-the-art units. In order to meet these objectives the outdrive was designed to incorporate a multi-strand roller chain drive (40), replacing the conventional bevel gear arrangement. Using a chain drive in this application serves to increase durability of the outdrive, while keeping the outer (43) casing very streamlined.
