Abstract: ABSTRACT OF THE DISCLOSURE   A maximum frequency detector having a counter  which counts through a cer-tain number of counts unless an inhibit signal is received at a rate deter-mined by the frequency of the clock  pulse received.  The inhibit signal is generated by a logic network to prevent the counter from producing an out-going digital  pulse of the digital pulse stream.  The  counter, the clock pulse generator and the logic  network cooperate to have the frequencies of the incoming and outgoing digital  pulses equal unless the incoming digital pulse stream has its frequency  exceed the predetermined maximum frequency. In the  event  that the  frequency  of the  incoming  digital  pulse stream exceeds the  predetermined maximum frequency the  frequency of the outgoing digital pulse stream is the certain predetermined maximum frequency.

Abstract: Abstract A wrap element and tip seal are disclosed for use in fluid apparatus of the scroll type which include a wrap element having a groove disposed within its tip surface of spiroidal configuration generally conforming to that of the wrap element.  A tip seal is disposed within the groove and comprises a plurality of strips of material disposed at least partially within the groove and arranged in side-by-side relationship at least partially across the width of the groove, each said strip extending along a longitudinal axis about the spiroidal configuration of the groove.  By fabricating the seal from a plurality of strips of material, the necessity for expensive machining operations is obviated while a seal is provided which is relatively flexible in a radial direction as to accommodate the precise groove shape, while remaining relatively inflexible in an axial direction so as to provide the desired sealing characteristics.  A variety of back-up means are disclosed for imposing a force upon the plurality of strips in an axial direction away from the wrap element while permitting movement thereof in an axial direction, thereby providing a desired sealing force while also affording a certain amount of axial compliance within the fluid apparatus.

Abstract: RCA 74,891 ABSTRACT OF THE DISCLOSURE A high voltage ultor power supply for a television receiver includes a ferroresonant transformer that is capable of operating over a substantial range of temperature without thereby introducing undesirably large changes in the ultor voltage.   The ferroresonant transformer comprises a plurality of windings, a magnetizable core with first and second core sections, and a resonating capacitor.  A first of the plurality of windings is wound on the first core section and coupled to a source of exciting current for generating magnetic flux in the core.  A second of the plurality of windings is wound on the second core section.  The varying magnetic flux that links the second winding generates an alternating polarity output voltage across that winding.  To regulate the output voltage, the capacitor is coupled to one of the plurality of windings and develops a circulating current to produce a magnetic flux that aids in magnetically saturating the second core section.  The first core section is operated in the magnetically unsaturated or linear region of the B-H loop characteristic of the magnetizable material forming the first core section.  A high voltage circuit, responsive to the regulated output voltage, develops the television receiver ultor voltage. The material of the magnetically saturating second core section is selected to have a higher Curie temperature than that of the nonsaturating first core section, resulting in relatively small temperature dependent changes of the ultor voltage.

Abstract: ABSTRACT OF THE DISCLOSURE             PRECISION ELECTRONIC SPEED CONTROLLER              FOR AN ALTERNATING-CURRENT MOTOR     A high  precision  controller  for  a  multi-phase  ac electrical  motor  that  is  subject  to a  large  inertial load.    The   controller   was   developed   for   and   is particularly  suitable  for  controlling,   in  a  neutron chopper  system,  a heavy  spinning  rotor  that  must  be rotated in phase-locked synchronism with a reference pulse train that is representative of an ac power supply signal having  a  meandering  line  frequency.   The  controller includes  a  shaft  revolution  sensor  which  provides  a feedback pulse train representative of the actual speed of the motor.  A timing signal generator provides a reference signal which is  compared with the feedback signal  in a computing unit to provide a motor control signal.  In the preferred  embodiment,  the  motor  control signal  is  a weighted linear sum of a speed error signal, a phase error signal, and a drift error signal, the magnitudes of which are recalculated and updated with each revolution of the motor  shaft.   The  speed  error  signal  is generated by a vernier-logic  circuit  which  is  drift-free  and  highly sensitive to small speed changes.  The phase error signal is  also  digitally  computed  with  adjustable  sensitivity around a zero mid-scale value.  The drift error signal is generated by long-term counting of the phase error and is used  to  compensate  for slow  changes  in  the  average friction drag on the motor.  The stator windings of the motor  are  driven  by  two  power  amplifiers  which  are controlled by the motor control signal.

Abstract: ABSTRACT OF THE DISCLOSURE         In a thin film electroluminescent element comprising a phosphor thin film, a dielectric thin film disposed on at least one of surfaces of the phosphor thin film and electrodes for applying a voltage across the thin films, the aforementioned dielectric thin film is formed of a dielectric material expressed by a general formula of AB2O6 (where A represents a divalent metal element and B represents a pentavalent metal element).  By employing the dielectric material, the voltage for driving to thin film electroluminescent ele-ment can be lowered without decreasing brightness of the element.  Further, by using a composite dielectric thin film in which the dielectric thin film expressed by the aforementioned general formula AB2O6 is laminated thereon with a dielectric thin film insusceptible to dielectric breakdown of self-healing type, the com-posite dielectric thin film is susceptible to the dielectric breakdown of self-healing type.          Additionally, the value of product of the dielectric breakdown field intensity and dielectric constant is increased, to allow the thin film electroluminescent element having excellent characteristics to be realized.
