Title: Ultrasonic horn driving apparatus and method with active frequency tracking
Inventor: ELBERT LAWRENCE E
IPC: G01N29/00
Filed: 1987-12-11
Granted: 1992-04-28
Abstract: ULTRASONIC HORN DRIVING APPARATUS AND  METHOD WITH ACTIVE FREQUENCY TRACKING                 ABSTRACT OF THE DISCLOSURE            The actual resonant frequency of an ultrasonic horn is tracked actively while the horn is operating in a working environment, such as in a clinical analyzer where the horn is partly immersed in a liquid bath in which a series of liquid-filled cuvettes are passed near the horn to dissolve solid tablets in the cuvettes.  The horn is driven initially by a signal of fixed amplitude but at a frequency which is varied between set limits about a nominal resonant frequency. Ultrasonic vibration waves of  the horn are sensed and fed back for rectification and peak detection over the scan operation.  The peak feed back level is held and a second scan is initiated with the drive signal at the same fixed amplitude.  When the rectified feedback signal level substantially attains that of the held peak level, a comparison is determined and control logic acts to lock on the frequency  at which the comparison was established for a given operating time period.

Granted: 1998-03-17
Abstract: A method to express rotavirus genes in a baculovirus system.  Different clones are used to express rotavirus genes for all of the viral proteins. These proteins are isolated in their native conformation.

Title: Active snubber structure and method for an electronic power inverter
Inventor: VANDERHELST PETER W
IPC: H02M7/5387
Filed: 1988-11-04
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE Active snubber structure and method for use with an electronic power inverter to reduce turn off losses in electronic switches in the power inverter. The snubber structure includes a resistor and a capacitor connected in series with each other and in parallel with the load on the power inverter and parallel, inverse connected silicon controlled rectifiers connected in parallel with the resistor for selectively shorting the resistor. In the method of use of the active snubber structure, electrical energy is stored in the capacitor connected in parallel with the load during on time of the inverter and the resistor is shorted immediately prior to the off time of the inverter whereby the capacitor charges substantially to the value of the source of direct current electrical energy during the on time of the inverter and on shorting of the resistor during off time of the inverter, the voltage across the load changes slowly so that the switches of the inverter can transition from on through a resistor like turn off stage, to completely off before there is appreciable voltage across them.
