Title: Pyridonecarboxylic acid derivatives
Inventor: HAYAKAWA ISAO
IPC: A61P31/04
Filed: 1992-05-27
Granted: 2001-12-04
Abstract: Quinolone derivatives are known as synthetic antimicrobial agents having a condensed pyridonecarboxylic acid skeleton, and those having substituents on various replaceable positions of said skeleton are known. In particular, if diastereomers exist, there are 4 or more kinds of stereoisomers. A mixture of diastereomers is a mixture of isomers having different physical properties and is difficult to apply as a drug as such. The present invention provides an antimicrobial 1-(1,2-cis-2-fluorocyclopropyl)-substituted quinolone derivative represented by formula I shown below which, although involving diastereomers, consists of a single stereoisomer.   (see formula I) wherein R1 represents a methyl group, a difluoromethyl group, etc.; R2 represents a saturated nitrogen-containing heterocyclic group; A represents C-X3 or a nitrogen atom; X1 and X2 each represents a halogen atom; and X3 and Z represent a hydrogen atom, etc.

The rigid mold assembly includes rigid members that act as reactive surfaces for cure pressures, and rem-ovable end and wedge members for assembling/disassembling of the rigid mold assembly, "T" mold assembly combination. The "T" mold assembly is operative during the cure process to generate the pressure required to cure the legs of one set of the stiffen-ing members. The "T" mold assembly includes complementary first and second pressure blocks that define the configuration of the one set of stiffening members. At least one of the complementary pressure blocks has a thermally expansible material encap-sulated therein that is operative, in response to elevated temperatures experienced during the cure process, to expand, causing the complementary pressure blocks to exert the pressure necessary to cure the legs of the one set of the stiffening members.

Patent CA-2129559-C (CA)
Inventor: JOHNS ROGER P
IPC: E21B10/06
Filed: 1994-08-05
Granted: 1998-07-21
Abstract: A roller cone drill bit is disclosed that leaves uncut a formation core having a diameter from 10% to 25% of the bit gage diameter. Cutters in circumferential rows away from the apex of the cones extend a sufficient distance closer to the centerline of the rock bit than the core cutters at the apex of a cone for breaking the central core. The bit is designed to have normal sizebearings, cone shell thickness and cutter protrusion to allow the use of standard drilling weights and rotary speeds, thereby achieving a significant increase in drilling rate. When drilling abrasive formations, ultra hard cutting teeth are used in the cone apex to maintain the core diameter.
Patent CA-2130346-C (CA)
Inventor: HALL STEPHEN H
IPC: G01N27/30
Filed: 1993-04-14
Granted: 2003-08-12
Abstract: The present invention is a reference half-cell electrode wherein intermingling of test fluid with reference fluid does not affect the performance of the reference half-cell over a long time. This intermingling reference half-cell may be used as a single or double junction submersible or surface reference electrode. The intermingling reference half-cell relies on a capillary tube having a first end open to reference fluid and a second end open to test fluid wherein the small diameter of the capillary tube limits free motion of fluid within the capil-lary to diffusion. The electrode is placed near the first end of the capillary in contact with the reference fluid. The method of operation of the present invention begins with filling the capil-lary tube with a reference solution. After closing the first end of the capillary, the capillary tube may be fully submerged or partially submerged with the second open end inserted into test fluid. Since the electrode is placed near the first end of the capillary, and since the test fluid may intermingle with the reference fluid through the second open end only by diffusion, this intermingling capillary reference half-cell provides a stable voltage potential for long time periods.

Granted: 2006-01-24
Abstract: A speed controlled pig for use in a pipeline has an essentially hollow housing through which gas or other pipeline liquids can flow from the rear of the housing, through the housing and subsequently out of the housing. A first bonnet, having several openings, is mounted at the front of the housing on a shaft which is oriented parallel to the longitudinal axis of the housing. A second bonnet is mounted on the housing and fits over the first bonnet. The second bonnet has openings which, when aligned with the openings in the first bonnet, permit the flow of pipeline fluids out of the housing. The first bonnet is movable in relation to the second bonnet so as to vary the degree of alignment of the openings in the bonnets. By varying the degree of alignment of the openings in the bonnets, the flow of liquids through the housing is regulated so as to control the speed of the pig. A control module is located in the interior of the housing for controlling the operation of the pig.
