Title: Colorimetric titration - using an optical endpoint detector
Inventor: DAHMS HARALD
IPC: G01N31/16
Filed: 1973-02-13
Abstract: The colorimetric titration of a liquid having different light absorption characteristics on different sides of a colour change interval indicative of a predetermined endpoint is effected by forming titrant ions within the liquid and passing light through to generate first and second electrical signals respectively. The signals are indicative of the intensity of light passing through the liquid on each side of the colour change interval. A third signal corresponding to the logarithmic ratio of the first two is produced and the titation continued until this ratio reaches a predetermined value, indicative of the endpoint. The quantity of titrant then added or if the titrant ions are produced by electrolysis, the amount of electricity then passed up to that time, is measured. The amount of chloride and bicarbonate ions in blood serum can be determined.

Patent DE-2429263-A1 (DE)
Title: Transforming mechanical movement into pneumatic signal - using pneumatic constant resistance device to control relay
Inventor: JUROWSKIJ ALBERT J
IPC: G01B13/00
Filed: 1974-06-19
Abstract: Air passes from the pipe (2) through the passages (9) and (10) through the pipe (16) and out through the nozzle (8). The quantity of air flowing through the nozzle (8) depends on the size of the gap between the nozzle end face and the plate (7). If the flow is reduced the velocity of the air through the holes (9) and (10) is reduced, reducing the suction effect in the chamber (13) causing an increase in pressure. Thus the pressure of the air supplied to the relay (1) depends on the size of the gap between the nozzle (8) and plate (7). The design of the relay is such that the output pressure in the pipe (3) varies linearly with this gap.
