Title: Calorimeter, in particular for heating systems
Inventor: HOENTZSCH CHRISTOF DR
IPC: G01K7/34
Filed: 1981-03-18
Abstract: A calorimeter, in particular specified for use with heating systems, which has a temperature sensor (10) which provides an output signal which is frequency modulated in accordance with the temperature acting on it. A downstream distance discriminator (24-28) distinguishes those pulses of the temperature sensor output signal which on the basis of the temporal distance are assigned a temperature which is below the lowest normal operating temperature of the heat-dissipating body. The pulse distance discriminator consists of an AND element (24) and, upstream of one of its input terminals, a delay line (26, 28). An additional frequency generator (16, 18, 20) is used for the purpose of generating from the temperature sensor output signal a low-frequency read signal, which is then further processed in the pulse distance discriminator (24-28). A further circuit (38, 40) is provided in order to reduce the number of the pulses effectively fed from the pulse distance discriminator (24-28) to a downstream counting device (42), and this permits the bead frequency to be located at a value greater than zero in the case of room temperature. A temperature sensor (84) for use in such a calorimeter has a liquid-filled pressure cell (94, 100) which has a metallic diaphragm (100) and a metallic plate (96) opposite the latter. Said plate can be thermally coupled to the heat-dissipating body, and forms together with the diaphragm (100) a condenser of variable capacity which is connected as a frequency-determining component to a resonant circuit. <IMAGE>

Title: Method and apparatus for chemical analysis
Inventor: MANABE SUGIO
IPC: C12Q1/00
Filed: 1982-03-11
Abstract: To analyse chemical substances in a sample with the aid of a reagent, for example an enzyme, a first test solution, which contains the sample to be analysed and a first reagent, is subjected to a photometric measurement with the aid of a first photometer (7, 8) in order to obtain a first measurement. The first measurement is compared with a predetermined standard range. If the first measurement is not outside the standard range, it is printed out as the final measurement. If the first measurement is outside the standard range, a second reagent having a higher concentration than the first reagent is added to the first test solution and the reaction is continued further. The second test solution is then subjected to a photometric measurement using a second photometer (16, 17) in order to obtain a second measurement which is printed out. The first and second measurements are processed further in order to derive a final measurement. The amount of very expensive reagent required is markedly reduced and a precise, less expensive analysis can be carried out. <IMAGE>
