Title: Psychrometer with differential circuit for wet and dry resistors - and PTFE mounting for evaporation body
IPC: G01N25/64
Filed: 1973-10-10
Abstract: Psychrometer has a pair of temp.-dependent electrical resistors, at least a first of which has a current passed through it ot raise its temp. Both resistors are each in a closed chamber, one chamber being gas-permeable. Evap-n. n. liq. is uniformly fed from a supply container to an evapn. body consisting of absorbent matl. and surrounding the first resistor within the gas-permeable chamber. A differential circuit is connected to a voltage source and compares the resistance of the 2 resistors; a unit is connected to it for indication of the humidity, proportional to the difference of the resistance values, of the gas in the environment of the appts. Pref. the thin-walled mounting for the evapn. body is of PTFE. The gas does not have to be set in motion, and erroneous readings are avoided.

Title: High efficiency agitator - for chemical mixers capable of withstanding high circumferential speeds without vibrational damag
IPC: B01F7/00
Filed: 1971-03-15
Granted: 1972-08-04
Abstract: High liq. flow speed are achieved allowing otherwise impossible chemical reactions to be carried out without excessive loads on the agitator blade base, or danger of vibration damage, particularly to the enamel blade coating. The agitator has two or more hollow enamelled blades of reducing outer cross-section between hub and outer blade ends. The blades may be attached relative to their centre line at any angle, so that, referred to their calculated circumferential speed, they move the liq. parallel to the drive shaft, either up- or downwards. The agitator hub may be permanently fixed to the drive shaft, or it may be detachable, using a draw bolt within a hollow drive shaft, enabling counterbalancing after enamelling. The tapered shape provides high strength at the blade base and even dynamic loading, thus making high speeds possible with small blades producing making strong liq. flow axially.

IPC: G01R27/26
Filed: 1989-05-18
Abstract: Die Erfindung betrifft ein Verfahren und eine Schaltungsanordnung zur Auswertung von Kapazitaetswerten bei analogen kapazitiven Sensoren. Die Erfindung wird in der Mesztechnik zur Eliminierung des negativen Einflusses parasitaerer Kapazitaeten auf die Kennlinien kapazitiver Sensoren verwendet, um so Meszwertaufnehmer, die eine hohe Empfindlichkeit und einen groszen Aussteuerbereich besitzen, zu erhalten. Durch eine Zeitausblendung wird der Einflusz der parasitaeren Kapazitaeten auf das Ausgangssignal beseitigt. Dabei wird die Gesamtkapazitaet des Sensorelementes als eine Parallelschaltung aus einer veraenderlichen Kapazitaet und einer unerwuenschten konstanten Kapazitaet angenommen. Dieser kapazitive Sensor wird in einem Oszillator, der eine lineare Abhaengigkeit der Perioden von der Kapazitaet aufweist, angewendet. Die Gesamtperiodendauer des Oszillatorausgangs wird durch die Teilzeit t1 - Parallelkapazitaet - und t2 - veraenderliche Kapazitaet - bestimmt. In das Zeitintervall t2 wird ein Impuls von konstanter Dauer und Amplitude in halber Laenge, waehrend die veraenderliche Kapazitaet ihren Ruhewert hat, eingegeben. Die sich dabei ergebende Rechteckimpulsfolge wird einem Mittelwertbildner zugefuehrt. Da diese nur waehrend der Teilzeit t2 erfolgt, hat t1 keinen Einflusz am Ergebnis der Mittelwertbildung des Ausgangssignals.{Schaltung; Kapazitaet; Spannung; Signal; Sensor; Impuls; Mittelwert, proportional, linear; Kennlinie}
