Patent CA-2171342-A1 (CA)
Title: Method and apparatus for absorbing hydrogen sulphide
Inventor: SIMONSSON ERIK
IPC: C01B17/66
Filed: 1994-09-07
Abstract: A method and an apparatus for selectively removing, by liquid absorption, hydrogen sulphide from a gas containing both hydrogen sulphide and carbon dioxide, are disclosed. In a first stage of the method, the gas (3) is in a container (1) contacted, in at least one step, with a carbonate-containing alkaline solution whose pH is adjusted during the absorption by the addition of a hydroxide, such as sodium hydroxide. In a second stage of the method, the gas is combusted in a combustion device (32) for converting the hydrogen sulphide remaining in the gas to sulphur dioxide, which then is absorbed in an alkali-containing solution, such as a sodium hydroxide solution, in a wet cleaner (36). By combining the absorption of hydrogen sulphide in a carbonate-containing solution in a first stage, and the combustion of the remaining hydrogen sulphide to sulphur dioxide and the absorption of the formed sulphur dioxide in an alkaline solution in a second stage, one may attain a total hydrogen-sulphide separation of high selectivity, high degree of separation and good process economy.

Patent CA-2173596-A1 (CA)
Inventor: BAKER CLARK R JR
IPC: A61B5/00
Filed: 1994-09-28
Abstract: The present invention provides an improved method and apparatus for more accurately calculating and measuring vital information such as oxygen saturation and pulse rate when an ECG signal is not available. Instead of using an ECG R-wave as a trigger to overlay optical pulses, a virtual trigger is generated based on the heart rate and used to overlay optical pulse data. The optical information from a number of periods is added together, with the beginning of each period being determined by the issuance of the virtual trigger. In this way, the maximum and minimum of the optical signal should be lined up with each other in each period and added together to give a cumulative maximum and minimum.  This enables precise identification of the maximum and minimum of the signal, and thus allows calculation of the oxygen saturation at that point.

Title: Fluorescence detection apparatus
Inventor: HAROOTUNIAN ALEC T
IPC: C12M1/34
Filed: 1995-12-06
Abstract: A fluorescence analysis system detects light transmitted from wells in a sample plate. One embodiment of the system includes a single light detector. A reflector is capable of receiving light from any one of several detection emitters and of reflecting the light toward the light detector. One reflector includes a prism which is mounted on a stepping motor. The prism is selectively rotated so that it faces each detection emitter in turn. The light from several wells in a row is directed toward the light emitter by rotating the prism to face, one-by-one, each of the emitters corresponding to the wells. The detection emitters include one end of an optical fiber bundle. The other end of each bundle is positioned near the wells, with each bundle positioned by a different well to carry light from that well to the corresponding emitter. A collimating lens is positioned between each detection emitter and the rotating prism to focus light from the emitter onto the prism. A baffle is positioned between the light detector and the prism. Light from a xenon arc excitation lamp is carried by optical fiber bundles toward the sample wells. A computerized controller coordinates light detection with the activities of an automated liquid handling system.
