Patent CA-2318013-A1 (CA)
Inventor: WILLIAMS KEITH S
IPC: B25B13/46
Filed: 2000-09-11
Abstract: A reversible drive mechanism for socket wrenches, having a detented selector cap thereon. The socket driving post of the wrench is fixedly attached to a triangular shaft rotatably contained within an internal cylindrical bearing surface, which is contained within the head of the wrench handle. Each face of the triangular shaft is a convex arc-shaped surface, and the cylindrical surface and the convex surfaces create between them three tune-shaped spaces. Each of the convex faces on the triangular shaft has tiltably mounted thereon a U-shaped fixture, which loosely contains within its arms a cylindrical roller. As the selector cap is rotated back and forth between selector positions, each U-shaped fixture tips back and forth on its respective convex face, and shifts the contained roller from one extreme to the other of its respective lune-shaped space. Each roller, when shifted, moves from being closely contained on one side of its tune-shaped space to being closely contained on the other side of its space and, when the wrench handle is rotated, the roller is frictionally wedged between the cylindrical surface and the convex shaft face, forcing the driving post and a socket mounted thereon in the desired direction. The lost motion of the wrench handle is reduced to less than 1-1/2 degrees.

Title: Analysis of quiescent anticoagulated whole blood samples
Inventor: WARDLAW STEPHEN C
IPC: G01N21/27
Filed: 1999-02-19
Abstract: Formed constituents of a quiescent anticoagulated whole blood sample are optically of visually analyzed in a sample chamber (14) which has a varying through plane thickness due to convergent opposing sample chamber walls (4, 8). At least one of the convergent walls of the chamber is transparent so that the blood sample constituents can be observed. The chamber's varying thickness produces a first lesser thickness region (A) in the chamber wherein a quiescent monolayer of red blood cells in the sample will reside after the sample is introduced into and fills the chamber. Larger formed constituents such as white blood cells in the sample are unable to enter the aforesaid lesser thickness region of the chamber. The red cells which reside in the greater thickness regions (B, C) will agglomerate to form rouleaux and lacunae. The exact thickness of the chamber at any particular location in the chamber can be predetermined, or can be determined in situ as the sample is being analysed. By admixing certain dyes with the blood sample, various characteristics and other information can be derived from the various formed constituents in the sample by means of a scanning instrument (54) which is able to measure various color and other signals emitted from the sample at various locations (1, 3, 5) within the chamber, or by means of visual examination of the sample in the chamber. The thickness of the lacunae areas of the sample can be calculated by the instrument as a function of signal emission strength from the dyes or stains. The emissions can be the result of sample fluorescence or can be the result of signal density through the sample. Particle volumes can be measured as a function or signal emission suppression caused by the particles. Erythrocyte sedimentation rates (ESR) can also be derived from a blood sample disposed in the sampling chamber.

Patent CA-2331931-A1 (CA)
Inventor: BETANCOURT PAREJA WILSON ANCIZ
IPC: F04B47/02
Filed: 2001-01-23
Abstract: A hydraulic-pumping unit is used for the operations of water and oil wells. It consists in a mechanism mounted on the top of the water or oil well. The hydraulic-pumping unit lifts up the sucker rods of the reciprocating pump.  The hydraulic-pumping unit has a hydraulic balance. Others lifting units like conventional pumping units have a loading balance or air balance with the weight of the well fluids and sucker rods. Due to construction of conventional pumping units the sucker rods of the reciprocating pump bear more use per year, more wear off and they could be broken. The Q-rate in barrels per day is direct function of S-stroke in inches and n-strokes per minute. These two parameters are very important to pump up fluids from the bottom well. The conventional pumping units have a relatively short stroke and high speed and the invention of hydraulic-pumping unit has the long stroke and very low speed for the same rate.      The hydraulic-pumping unit represents the unique mechanism with the well-known Pascal's principle.    The hydraulic-pumping increases the sucker rod life service and the pump as well. The novel of this invention is that it can be manufactured by having a great height to obtain a very low speed.
