Title: Rocking beam vortex sensor
Inventor: KLEVEN LOWELL A
IPC: G01F1/32
Filed: 1988-09-14
Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE          A vortex sensor used in a vortex  flowmeter that has a single sensing diaphragm parallel to the direction of flow that is sensitive to differential pressures  caused  by  vortices  shed  by  a  vortex shedding bar associated with the sensing diaphragm. A beam is attached to the sensing diaphragm and it transfers  the  deflecting  motion  of  the  sensing diaphragm due to differential pressures to a sensor external to the flow passageway.  The sensor provides an output indicating motions of  the beam caused by the  beam  pivoting  when   the   sensing  diaphragm deflects.   The  beam  preferably  is  pivoted  on  a relatively rigid, fluid-tight isolator diaphragm with one end of the beam on the outside of the isolator diaphragm.   The  sensing diaphragm which  is used to measure differential pressure rejects variations  in the static pressure, that is, increases and decreases of  the  static  pressure  on  both  sides  of  the diaphragm, which is a common source of problems with existing vortex flowmeter sensors.

Abstract: GAMMA RADIATION DETECTOR WITH ENHANCED            SIGNAL TREATMENT                       ABSTRACT OF THE DISCLOSURE A hand-held gamma radiation probe is employed to locate radiation concentrations in animal tissue in conjunction with a control function providing an enhanced audio output particularly suited for cuing the user as to source position. The probe is positioned at a location on the animal body representing background radiation and a squelch low count rate is developed therefrom. The squelch low count rate is multiplied by a range factor to develop a squelch high count rate and frequencies are developed from a look-up frequency table from lowest to highest in correspondence with the developed high and low squelch count rates. Slew rate limiting of the count rates is provided by development of a squelch delta value representing the difference between the squelch high and low count rates divided by a time element. Selection of frequencies for audio output from the frequency table is limited by the value of the squelch delta value. A weighting of received radiation counts is carried out continuously to develop count rate values used by the system.
