Patent EP-0069647-A2 (EP)
Inventor: ANTONAZZI FRANK JOSEPH
IPC: G01L9/12
Filed: 1982-06-28
Abstract: A pressure ratio measuring system is disclosed. The system includes two quartz capacitive pressure transducers (16, 22). Each capsule contains a pressure sensitive capacitor (Csa, Csf) which is fed by an alternating excitation signal. Capacitance (Csa) is fed by excitation signal (Vr) and Capacitance (Csf) is fed out of phase by feedback excitation signal (-Vrf(N)). The outputs of the capacitance are combined in a summing junction (36) whose output is an error signal (1e) proportional to the pressure ratio. A feedback loop (26) is closed through a register (30) and a multiplying digital to analog converter (32) to generate the feedback signal (-Vrf(N)). The feedback loop (26) integrates the error signal (1e) by incremental changing the feedback signal (-Vrf(N)) with digital number (N) in a direction to null the loop. When the loop is nulled the digital number (N) is a representation of the ratio (Pa/Pb) of the pressure (Pa) sensed by capacitance (Csf).

Abstract: Ultrasonic wave attenuation in an object is determined from the number of zero crossings of a plurality reflected signal as a function of depth. The zero crossing density is indicative of the frequency spectrum, and by comparing the zero crossing density at one level to the zero crossing density at asecond level a measure of attenuation therebetween is obtained. A time gain control signal for a variable gain amplifier is based on the cumulative attenuation of the signal through the object. Attenuation between a first depth and a second depth is determined from a comparison of the averaged measure at the first depth and the averaged measure at the second depth. The ultrasonic wave is directed through a plurality of limited volumes of the object along a plurality of vectors. The frequency shift of reflections of the ultrasonic wave along each vector determines a measure of the attenuation. The attenuation of each limited volume from each vector intersecting the limited volumes is averaged. Frequency dependent scatter perturbations are identified and eliminated form the measured frequency. Apparatus for implementing the method comprises a zero crossing detector such as a Schmitt triggered monostable multivibrator and a pulse counter.

Abstract: The invention relates to a device for centrifuging and simultaneously transferring energy from a rotating drum which is to be braked cyclically. The two drums are made to rotate by accelerating and decelerating them cyclically in each case in their directions of rotation by a force transmission which transmits the energy released when braking the first rotating centrifuge drum into acceleration of the stationary second centrifuge drum. According to the invention, the brake required for the operation, subsequent to the energy transfer, of the one centrifuge drum at a high speed of rotation is replaced or supplemented at the centrifugal drum lying opposite and running with a low speed of rotation by means of a free-wheel or similarly acting unit. The invention also alternatively provides for the mechanical/ electrical force transfer to occur by means of two asynchronous motors connected to the drum, which motors are connected to one another by means of the DC sides of the respective voltage changers associated with the asynchronous motors. <IMAGE>   <IMAGE>

Abstract: A novel method is provided for the production of anhydrous hydrofluoric acid from low-grade metallic fluorides using an intermediate aluminum fluoride compound. The method involves the reaction of low-grade metallic fluorides such as fluorspar with sulfuric acid to produce weak hydrofluoric acid. The weak acid is then reacted with a metallic salt (such as aluminum chloride) to form precipitated aluminum fluoride (AlF 3 ·3H 2 O). After dewatering, the aluminum fluoride is reacted with strong sulfuric acid to form aluminum sulfate and strong hydrofluoric acid.
