Patent CA-2371776-A1 (CA)
Inventor: CHINN DOUGLAS O
IPC: A61B18/02
Filed: 1999-05-25
Abstract: A cryosurgical probe (6) and method for treating cancer by cryosurgically destroying cancer cells by way of an ice ball (10) formed at the distal end (8) of the cryosurgical probe (6) and located in proximity to the cancerous tissue to be treated. The probe (6) is surrounded by a thermally insulating sheath (12, 14, 16, 20). By varying the length and thickness of the thermally insulating sheath (12, 14, 16, 20) as well as the length of the unsheathed distal tip (8) of the probe, the size and shape of the ice ball produced by the cryosurgical probe (6) can be tailored to correspond to the size, shape and location of the cancerous tissue so as to localize the cryogenic effect.  Alternatively, the size and shape of the ice ball can be controlled by surrounding a cryosurgical probe (30) with a heated sheath (32) having a heating element (34) and a temperature sensor (38) to detect the temperature to which the sheath (32) is heated.

Inventor: QUESADA MUNIZ VIVIAN DE JESUS
IPC: C12Q1/10
Filed: 2001-04-17
Abstract: The invention concerns the field of microbiology, more particularly, a composition and a method for the detection, identification and early countin g of microscopic organisms, more specifically gram-negative microorganisms. Th e composition described in the invention consists of a mixture of protein substances, with a total nitrogen content of between 9 and 20 % and a ratio of 2:1 and 24:1 in relation to the content of gram-negative microorganism inhibitors used in said mixture. The composition also contains a mixture of organic and inorganic substances facilitating differentiation of gram-negati ve microorganisms, said mixture having a ratio of between 0.5: 1 and 2:1 relati ve to the mixture of protein substances. Said composition makes it possible to perform detection and differentiated counting of E. coli and other coliform organisms due to the blue-green color of their colonies on an orange background of the medium; Salmonella non typhi owing to the red color of the  center of the colonies on a pink background of the medium; Salmonella typhi and Proteus due to the transparency of the colonies; Citrobacter and Klebsiella owing to the violet coloring of the colonies on a pink to orange background of the medium, and Pseudomonas aeruginosa due to the orange coloring and dark center of the colonies and greenish pigmentation after 24 hours of incubation, which emit yellow-greenish fluorescence under ultraviol et light.

Patent CA-2387195-A1 (CA)
Inventor: SZARKA DAVID D
IPC: E21B34/00
Filed: 2002-05-22
Abstract: A tubular tool body carried at the end of a drilling rig top drive is received within a drill string being used as a landing string to position casing in a wellbore. External threads on the tool body can be mated with the box threads of the drill string to secure the top drive and drill string together for simultaneous drill string movement and fluid circulation. An annular seal carried about the tool body engages and seals with the internal wall of the drill pipe to prevent drilling fluid leakage when the tool body is received within the drill pipe without thread engagement. The tool has an internal check valve that opens to allow back flow of drilling fluid that may be displaced from the drill pipe as the pipe is lowered into the well. The check valve prevents standing fluid in the top drive from spilling onto the rig floor when the tool is withdrawn from the drill string. Pump pressure applied through the top drive axially moves the check valve against a biasing spring to open a bypass through the wall of the tool to permit forward circulation through the drill string and casing. The spring bias force is sufficient to withstand the hydrostatic force exerted by the standing column of fluid in the top drive and associated piping.

Abstract: A sample module for use in a downhole tool includes a sample chamber for receiving and storing pressurized fluid. A piston is slidably disposed in the chamber to define a sample cavity and a buffer cavity, and the cavities have variable volumes determined by movement of the piston. A first flowline is provided for communicating fluid obtained from a subsurface formation through the sample module. A second flowline connects the first flowline to the sample cavity, and a third flowline connects the first flowline to the buffer cavity for communicating buffer fluid out of the buffer cavity. A first valve capable of moving between a closed position and an open position is disposed in the second flowline for communicating flow of fluid from the first flowline to the sample cavity. When the first valve is in the open position, the sample cavity and the buffer cavity are in fluid communication with the first flowline and therefore have equivalent pressures.
