Title: Simultaneous measurement of multiple system parameters for a flowing liquid, such as may be required for medical diagnostics, or on-line process monitoring
Inventor: PROGHOSSIAN ARSHAK
IPC: G01N27/44
Filed: 1999-01-14
Abstract: An arrangement for measurement of physical parameters for liquids comprises a generator (1), a detector (2), and a liquid flow channel (3). The generator and detector devices extend into the liquid in the channel and are mutually separated by a distance (S). The generator produces a chemical at concentrations which are detectable, after a time interval, by the device (2).  An Independent claim is included for a measurement process in which a concentration of a chemical is produced by a generator at an instant (t1), that this concentration is measured after an interval by a detector, that the time (t2) is registered when the detected concentration reaches a pre-determined threshold value, and that the interval (t2-t1) is calculated. Typical generator functions are production of ions (e.g. H<+>, OH<->) , gases (e.g. O2, H2), using gold, platinum or iridium electrodes. The detector electrode may be an ion selective electrode, an ion sensitive field effect transistor (ISFET), or an EIS (electrolyte-insulator-semiconductor), etc. The arrangement can incorporate sensors which allow measurement of liquid temperature (semiconductors), pressure (capacitance sensors),flow rate, electrical conductivity ( semiconductors),oxygen content (Clark Electrode), carbon dioxide content, etc.

Title: Dilution of blood sample for testing
Inventor: BERNDTSSON INGEMAR
IPC: G01N1/10
Filed: 1999-02-04
Abstract: For the dilution stage of testing a blood sample, using a given volume of the blood held in a capillary tube, an adapter is prepared to hold the capillary tube and be connected to the supply line for the diluting fluid. The diluting fluid is passed through the feed line and the adapter, and at least partially through the capillary tube.  The blood, together with the diluting fluid, is caught in a vessel. The adapter (27) is inserted into the feed line (22) for the diluting fluid, to hold the capillary tube so that the diluting fluid flow passes at least partially through the capillary tube. The diluting fluid feed line (22) connects the diluting fluid supply (14) to the mixing vessel (13). The adapter (27) has connectors to fit the diluting feed line sections (22a,22b). A fixed section of the adapter (27) has the connections, and a removable section with a holder for the capillary tube is to be fitted into the fixed section so that at least part of the diluting fluid flow passes through the tube through the inner channels of the adapter assembly. The tube holder has connections to link with the flow channels, so that the diluting fluid passes through the adapter and tube assembly. The holder has a tubular shape, with a larger inner cross section than the outer cross section of the capillary tube. An operating system starts the flow of diluting fluid, in response to the insertion of the capillary tube holder into the adapter.

IPC: F02G1/055
Filed: 1999-02-06
Abstract: The invention relates to a heating and refrigerating machine, especially a Vuilleumier heat pump or a Stirling engine, in which a gas-air mixture is combusted in a combustion chamber and the exhaust gas radiates thermal energy to the heating head serving as a housing for the hot piston of the engine which forms a portion of the combustion chamber with a part of the outer surface thereof. By virtue of a porous burner and of the adaptation thereof to the heating head, the transmission of heat by means of convection and radiation is improved and a compact machine construction is attained which transmits heat in a highly efficient manner with low pollutant values over a broad modulation range of output.
