Patent CA-1321488-C (CA)
Title: Biological sensors
Inventor: FINLAN MARTIN F
IPC: G01N33/543
Filed: 1988-08-12
Granted: 1993-08-24
Abstract: ABSTRACT     A sensor using the principle of surface plasmon resonance (SPR) to monitor the progress of the reaction between a sample (not shown) and a sensitive layer 20 (for example an antibody layer).  The layer 20 is applied to the rear surface of a metallic film 19 formed on the surface of an optically transmissive component 28 in the form of a hemicylindrical lens 11 and slide 16.  Collimated light from a source (not shown) is applied via a lens 2 which focusses the incoming beam 1 to a focus at point 3 to form a fan-shaped spread of light incident at point 3.  The light is internally reflected at point 3, and emerges from the component 28 to be applied to a detector array 18 which latter is electronically scanned.  The angle of incidence of the light at the point 3 is such as to span that angle which gives rise to surface plasmon resonance, together with a range of angles thereabout so that the progress of the resonant condition, as the reaction between the sample and the sensitive layer proceeds, can be monitored.

Abstract: ABSTRACT OF THE DISCLOSURE A roller skate is provided having a body portion adapted to be attached to the foot of a wearer, and front and rear axles attached to the body portion, the axles having wheels mounted to the ends thereof.  At least the front wheels are characterized by an outer cylindrical rolling portion having a plurality of teeth integrally formed on an inwardly facing circumferential surface thereof.  A pawl member having first and second ratchet-engaging portions has a cam follower portion and is mounted by a camming member to the body of the skate.  The camming member is movable between first, second and third positions.  In the first position, the camming member acts through its cam follower portion to elevate the pawl mem-ber to a position where it does not engage any of the teeth on the inwardly facing surfaces of the front wheels. In the second position, the camming member allows the pawl to ride in the teeth by its own weight, establishing a ratcheting relationship permitting rotation of the wheels in only a single direction.  In the third position, the camming member holds the pawl in the teeth formed in the front wheels so that the front wheels are restrained from moving in either direction.

Abstract: PERIPHERAL CARDIOPULMONARY BYPASS AND      CORONARY REPERFUSION SYSTEM                     Abstract An apparatus and system to arrest or reverse heart damage from myocardial infarction by using a peripheral, femoral-femoral full bypass along with the venting of the left ventricle wherein the rate at which blood is drawn from the femoral vein and the rate at which the left ventricle is vented are related in a predetermined manner.  The damaged area is treated with a cardioplegic solution; the blockage causing the heart attack is then removed by a thrombolytic solution or by angioplasty, while blood is prevented from entering the ventricle and from reactivating the heart from its at-rest condition.  Normal blood flow is then restored, and the various catheters and bypass mechanisms removed. The system is also useful for peripheral cardiopulmonary bypass systems not involving the application of a cardioplegic solution.  The catheters are specially designed for their function.

Abstract: Povidone is sterilized by irradiation in the presence of iodine and iodide ions. In particular solutions of povidone are sterilized by gamma-irradiating the povidone in the presence of iodine and iodide ions, which are present in an amount which prevents gelation at that dose of gamma radiation which would cause gelation in the absence of the iodine and iodide ions. The gamma irradiation of povidone may be effected in the presence of iodine with both iodide and iodate ions or as povidone-iodine in the presence of iodide and/or iodate ions. Sterilization thus effected by gamma radiation while preventing gelation of the povidone and degradation of the povidone-iodine.

Abstract: An hydraulic valve of the flow-controlled type and including a valve housing provided with inlet and outlet means and a valve body which is intended to coact with a valve seat in a manner to open and interrupt the connection between the inlet and outlet means in dependence on a continuously controllable pilot flow in a pilot-flow channel extending from a pilot-flow chamber located on the side of the valve body remote from the valve seat to the outlet in the flow direction after the valve body. The pilot-flow chamber, in turn, communicates with the inlet via a variable constriction. For the purpose of simplifying this type of valve and rendering the valve more compact, the valve body (9) is arranged in a recess (25) which extends to the valve seat (26) and which is formed concentrically with the valve seat. The recess (25) is formed in a seat-part (8) which incorporates one or more slots (34) which are open towards the recess (25) and which discharge into the pilot-flow chamber (27). The seat-part also includes at least one inlet port (19) which communicates with the inlet (2) and which also communicates with the slot or slots (34), such as to form the variable constriction, thereby providing a facility in which the valve body (9) can be moved continuously between its valve-open and valve-closed positions in a controllable manner.
