Abstract: L'oscillateur haute fréquence comprend un cristal piézoélectrique associé à au moins deux électrodes excitatrices et un dispositif permettant d'appliquer aux électrodes d'une part une puissance électrique d'excitation du cristal selon un mode utile choisi pour déterminer une référence de fréquence et d'autre part une puissance électrique additionnelle pour exciter le cristal selon un mode, un partiel ou une vibration anharmonique différents du mode utile choisi pour déterminer une référence de fréquence. Un dispositif est en outre prévu pour réguler la puissance électrique d'excitation du cristal selon le mode utile dans une proportion prédéterminée et constante par rapport à la puissance électrique additionnelle. Un tel oscillateur haute fréquence permet une compensation, par le défaut d'isochronisme dû à la vibration sur le mode utile, de l'effet amplitude-fréquence indirect produit par la vibration additionnelle, et inversement.

Abstract: FRIED POTATOES AND PROCESS                         Abstract The object of the invention is to enable the pre-paration of fried potato products with improved texture and texture stability.         Potato pieces, such as strip-shaped french fries or disc-shaped dinner fries, have better inner and outer textures and retain a desirable textural contrast between the two longer after finish frying where the surface of the potato pieces is   disrupted, preferably in   combination with a blanching step and most preferably when done after a surface skin has been formed by air drying or par frying. Improvements are also seen where the pieces are blanched sufficiently to substantially completely gelatinize the potato starch and preferably are infused with low molecular weight soluble solids and then washed sufficiently to remove some of the soluble solids. The soluble solids, such as sodium chloride, within the potato pieces help to hold moisture internally of the pieces and to retard its exit through the crisp surface skin formed by frying.  Infusions can be accomplished during blanching or thereafter.         Also disclosed is the preparation of fried potato products which can be quickly heated for consumption in conventional home ovens.  According to this aspect of the invention, the potato pieces are substantially fully cooked prior to freezing. The crispness of these products is enhanced by the surface disruption, blanching and infusion aspects of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE      A submersible well pump has a system for monitoring parameters  such  as  pressure  and  temperature  in  the vicinity of the motor.  The system includes a downhole assembly  in  the  well  that  has  a  transmitter  for generating a carrier signal and superimposing that signal onto  the  power  cable.   Transducers  in  the  downhole assembly sense physical parameters and provide a change in resistance corresponding to the physical parameters.          These  transducers  are  connected  to  a modulator which modulates the carrier signal according to the resistance.    A shift register in the downhole assembly sequentially shifts a reference resistor and two or more transducers into the modulating circuit to provide envelopes on the carrier signal corresponding to a synchronizing signal and to data being sensed.  The modulated carrier signal is demodulated at the  surface  into  separate channels, where each can provide a  readout proportional  to the physical parameter sensed.

Abstract: ABSTRACT OF THE DISCLOSURE          A  fire  detection system comprises  a  plurality  of individual fire detection-suppression units which  all have  their  own individual standby  electrical  power supply.  Each has radiation detection means for  fire detection  and its own source of fire suppressant.  In the event of any of the units detecting a large  fire, it  automatically  releases suppressant frog  its  own source.  In addition, all the units are connected to a master control station via a data bus.  Any individual unit  sensing  a large fire signals this fact  to  the master   control   station  which  then  enables   the immediately adjacent individual units so as to  permit those units,  only,  to release their fire suppressant if  and  only if they detect at least a  "small"  fire (and  also  provided that the master  control  station determines  that not less than a predetermined  number of  the  units still have functional fire  suppressant sources).   There is thus a measure of central control and  monitoring,  and  yet  each unit  is  capable  of operating completely independently in the event of its detection  of  a  large  fire.   An  emergency  button provides a completely independent means of  activating all  the  units.  The master control station  is  also capable of activating all the units.

Abstract: Abstract Debounce Circuit Providing Synchronously Clocked digital Signals An improved debouncer circuit is disclosed for providing debounced, synchronously clocked digital signals from a single-throw switch, as for instance, of the momentary contact type.  A signal, variable between two logic levels, is provided by the switch for input to the debouncer circuitry.  that input signal is applied as one input to an EXCLUSIVE OR gate, the other input to that gate being fed back from the Q output terminal of an output data latch having complementary Q and Q* output terminals.  The Q* output terminal of the data latch is connected to the D input of that latch such that a synchronous clocking signal appearing at the clock input of the data latch serves to toggle the states of the Q and Q* output terminals.  The signal appearing at either one of the output terminals Q, Q* of the output data latch may be used as the debouced signal provided to other circuitry, depending upon signal polarity needs.

Abstract: APPLICATION OF R. R. BAHN AND M. L. THOMPSON ELECTRICAL CONNECTOR FOR OXIDIZED SURFACE                 ABSTRACT       An electrical connector for an oxidized surface includes a plurality of spaced apart parallel connector legs integrally formed as extensions of a central connector spine. Each connector leg has a free standing integral barb projecting therefrom toward an adjacent one of the connector legs.  A group of legs is arranged to straddle a metal plate having an oxidized surface with the pointed ends of the barbs having separation less than the thickness o the plate to enable the barbs to scrape the oxide from the surface to establish electrical contact to the underlying metal layer.   The connector, in turn, is made of phosphor bronzed to enable a spring-loaded electrical contact to be made to the connector surface by providing a low resistance non-oxidizing contacting surface.  A use for such as connector would be to provide an effective electrical connection to aluminum plates such as those used in an electrostatic precipitator where the aluminum oxide forms and electrical current barrier and the connector is required to have an low resistance surface to contact a spring-loaded connector extending from a high voltage source to the collector plates.  The use of an extended connector spine enables the connector to bridge a pair of plates while providing individual electrical connections thereto.
