Abstract: The performance of a treating agent added to a body of water employed in a cooling tower is continuously monitored by real-time analysis of a spectral or chemical characteristic of an inert tracer proportioned to the treating agent, said characteristic being indicative of tracer concentration, and converted to a voltage analog. The voltage analog is compared to a monitor value representing par performance and if performance is nonstandard (nonpar) a signal is generated which alters the output of a pump which feeds the dosage of treating agent containing proportioned tracer.

Title: A method for measuring the free fraction of ligands in biological fuids
IPC: G01N33/53
Filed: 1989-01-05
Granted: 1991-06-12
Abstract: A one-step assay for the free portion of a ligand in a biological sample involves incubating a mixture of the sample with a labelled antibody for the ligand and a ligand analogue which competes with the ligand for binding to the antibody. The assay is characterized by using a monoclonal antibody and by choosing a ligand analogue which has a lower affinity for the antibody than does the ligand. An insolubilised ligand analogue preferably has a binding affinity for the antibody from 0.01% to 10% of that of the ligand. Ligand/ligand analogue pairs exemplified are T4/T3 (Thyroxine/Triiodothyronine); Testosterone/etiocholanol; and T3/T2.

L'unité de commande ci-décrite évalue le régime non seulement en fonction de la charge de travail mais également en fonction d'autres facteurs, corrige la vitesse fixée par un opérateur en fonction du résultat de l'évaluation globale, exécute une commande de changement de vitesse du moteur hydraulique de manière à obtenir une vitesse correcte et garantit dans tous les cas un fonctionnement sans à-coups. Après que la vitesse de rotation des moteurs hydrauliques en marche (10, 10') est commutée et déterminée par les organes de commutation vitesse élevée/vitesse faible (31), un état déterminé (vitesse élevée ou faible) est corrigé non seulement en fonction du résultat de l'évaluation de l'organe d'état de charge de travail (30) mais également en fonction du résultat de l'évaluation de l'organe d'évaluation (37) du régime de rotation du moteur, et similaire. Lorsqu'on actionne des soupapes de commutation (6, 6') pour obtenir une vitesse de rotation (vitesse élevée ou vitesse faible) après la correction, l'huile sous pression provenant des soupapes de commutation du sens de rotation (48, 48') est fournie sélectivement en réaction à l'actionnement des soupapes soit aux actuateurs à angle variable à plateau incliné (7, 7') (vitesse faible), soit aux actuateurs à angle variable à plateau incliné (8, 8') (vitesse élevée), et l'angle du plateau incliné des moteurs hydrauliques en marche (10, 10') est modifié de manière à obtenir la vitesse de rotation après correction.

Abstract: A method for determining the endogenous thrombin potential (ETP). which shows how much and for what length of time thrombin has been active in a sample of clotting blood or plasma. The ETP can be used for determining the effectiveness of treatment with antithrombotics of any type. Said ETP determination comprises adding to said sample a thrombin substrate, an activator of thrombin formation, a preparation of proteaseinhibitor and if desired a pharmaceutical for analysis . The thrombin substrate is preferably selected to not completely consume the amount of thrombin generated in the sample, to have a rate of conversion of the substrate which is proportional to the amount of thrombin present and to have a measurable conversion product resulting from the conversion by thrombin. Determination of the amount of conversion product leads to determination of the ETP. The choice of activator determines whether the effect is measured on the intrinsic or extrinsic clotting system, making it possible to determine the effect of the pharmaceutical, which is being analysed, on various parts of the clotting mechanism.
