Title: Monitoring one or more solutes in a biological system using optical techniques
Inventor: LIU HANLI
IPC: A61B5/00
Filed: 1995-12-04
Abstract: This invention is a scheme for monitoring a solute in a biological system comprising the steps of delivering light into a biological system (12) containing a solute, the light having a wavelength selected to be in a range wherein the solute is substantially non-absorbing;  detecting at least first and second portions of the delivered light (16, 18, 20), the first portion having traveled through the biological system along one or more paths characterized by a first average path length, and the second portion having traveled through the biological system along one or more paths characterized by a second average path length that is greater than the first average path length; and comparing the first and second portions of the delivered light to monitor concentration of the solute in the biological system. Also described are schemes for monitoring low molecular weight polyhydroxy solutes, generally sugars (mannitol, fructose, sucrose, glucose, sorbitol), alcohols (methanol, ethanol, propanediol), and electrolytes (sodium, potassium, magnesium, calcium, and chloride ions).

Patent CA-2224708-A1 (CA)
Title: Transformer
Inventor: MARKOV GENNADY ALEXANDROVICH
IPC: H01F30/06
Filed: 1997-04-10
Abstract: Several types of transformers are proposed which may be used as the main electrical engineering equipment of electric power stations, substations, power lines, in radio engineering, in devices for measuring, automatic control and regulation. At the basis of the invention lies the principle under which the primary winding consists of two sections wound and connected to each other in such a way that the magnetic flux created by one of such sections during operation of the transformer compensates the magnetic flux created by the other section of the primary winding.      The transformer comprises (Fig. 2) a magnetic circuit, a primary winding consisting of two sections wound in one direction on a core of the magnetic circuit and having an identical number of turns. The windings of the two sections are connected to each other by their outs, while the ins of the windings serve as inlets for the power supply. The secondary winding is wound on the primary winding on the same core of the magnetic circuit, a load R H is connected to the secondary winding.      The developed embodiments of the transformer are distinctive in that the sections of the primary winding are wound on one core of the magnetic circuit (3 embodiments) or on two cores of one magnetic circuit (4 embodiments), in that the direction in which the sections of the winding are wound is different (in one or opposing directions), and consequently there is a different connection of the windings, and are also distinguished by the presence of a secondary winding (in one embodiment there is no secondary winding).

Patent CA-2229941-A1 (CA)
Inventor: CLARK PHILIP G
IPC: B65G15/62
Filed: 1998-02-19
Abstract: The trucking floor of a belt conveyor is lined by liner sheets of UHMWPE that are fastened to the floor by bolts received through countersunk holes in the liner sheets and holes in the trunking floor. In each liner sheet one bolt is a primary locator and is received in close clearance with a hole in the trucking floor. All other bolt holes in the trunking floor are in free clearance with the bolt shanks so as to permit displacements of the floor relative to the liner sheet in all portions of the liner sheet remote from the primary locator hole due to differential thermal expansion and contraction of the liner sheet relative to the floor.      Secondary locator holes prevent the sheet from rotating about the primary locator hole by having close clearance with the bolt shanks in a direction transverse to a line between the primary locator hole and the secondary locator hole. The secondary locator holes are in free clearance with the bolts in the direction of the line to permit differential expansion/contraction in the direction of the line.

Title: Manipulation and adjustment of surgical instruments
Inventor: PAOLITTO ANTHONY
IPC: A61B34/20
Filed: 1998-05-22
Abstract: Surgical apparatus for performing cardiac surgery on the coronary organs of a patient comprising contacting means capable of providing a mechanical load on at least a portion of said coronary organ, a positioning means which allows the setting of either or both, said contacting means and coronary organ in any position or orientation within surgical workspace W, a manipulation means serving as a single point control to position and orient said contacting means onto said coronary organ tissue, and an adjustment means serving to bias the range of at least one motion degree of freedom of the surgical apparatus within a restricted limit than is otherwise achievable when said bias is not present or overridden.   This achieves the setting of the said contacting means in any position and orientation within the surgical workspace W, with or without the simultaneous manipulation, retraction, or stabilization of coronary organ tissue also within the W. Any of the motion degrees of freedom comprising the surgical apparatus are capable of being "biased". All motion degrees of freedom of the surgical apparatus are synergistically linked, whether biased or unbiased, through the manipulation means which the surgeon utilizes to set the contacting means or coronary organ tissue.

Title: Dual valve apparatus for enabling quick measurement of pressure
Inventor: VELTRI MICHAEL J
IPC: B60T17/22
Filed: 1998-09-24
Abstract: A dual  valve  apparatus  enables  quick measurement  of pressure contained within a housing.  The housing has a main body, a check valve housed in the main body and a cover whose removal renders the check valve accessible.  The check valve is normally compressed against a check valve seat to provide a first seal that prevents leakage of the pressure.   The dual valve apparatus includes a modified cover, a valve body and a valve stem.  The modified cover defines first and second bores axially offset from and in communication with one another.  The first bore is at least partially threaded.  When the modified cover is secured to the main body, the second bore is aligned with the check valve.  The valve body accommodates a valve bore from its protuberant end to its threaded end.  The protuberant end is shaped to mate with a female portion of a quick connect coupling.  The threaded end screws into the first bore of the modified cover.  Movable within the bores, the valve stem at its head end is normally compressed against a valve seat formed within the protuberant end of the valve bore to provide a second seal that further prevents leakage of the pressure.          Mating the female portion to the protuberant end of the dual valve apparatus causes the valve stem to move away from its seat.  The valve stem in turn unseats the check valve thereby providing access to and enabling measurement of the pressure.
