Abstract: METHOD AND APPARATUS FOR MEASURING ELLIPSE PARAMETERS    OF ELECTROMAGNETIC POLARIZATION IN GEOPHYSICAL                   EXPLORATION. Abstract of the Disclosure:            A method and apparatus for measuring ellipse parameters of polarization of an electromagnetic field are disclosed.  A receiver is provided having crossed coils, and both the receiver and transmitter have specific orienta-tions which are set up whenever the receiver and transmitter are situated at any location for testing for the presence of an anomaly at least in the region of the receiver.          When signals are detected on the crossed coils of the receiver, the receiver is maintained in its specific orientation while the signals from the crossed coils are examined at least so as to determine the phase difference quantity ? between the signals from the crossed coils and the magnitude ratio quantity r of those signals.  With the quanti-ties ? and r, such ellipse parameters of polarization of the resultant EM field in the region of the receiver as the tilt angle, ellipticity angle and ellipticity ratio thereof can be determined by mathematical analysis and processing.  In high noise situations, or where the signal level on either receiver coil is low, signal level stacking circuits are utilized to arithmetically add signal levels of succeeding signals until such time as one of the signals being stacked reaches a predetermined level.

Abstract: Abstract of the Disclosure A modulator for differentially encoded phase-shift keyed digital data is implemented entirely by digital means. Baseband serial binary data are illustratively transformed into dibit pairs which are assigned discrete quaternary carrier-wave phase shifts.  A "staircasing" shift register whose weighted outputs are combined to form a quantized phase-modulated carrier wave is advanced by a relatively high-speed counter through a frequency divider network.  The division rate of the divider is selectively accelerated in each baud interval in accordance with the assigned dibit coding.  The resultant quantized carrier wave is then low-pass filtered prior to application to a telephone trans-mission line.  By controlling the division rate of the divider rather than the advancement rate of the shift register, gradual transitions are imparted to the output carrier wave with minimal harmonic distortion.

Abstract: ABSTRACT OF THE DISCLOSURE      A strut or boom mounted probe having separate pres-sure sensing ports or sets of ports axially spaced on the side of the probe.  The ports are located on the probe so that as a reference angle of attack, normally zero angle of attack, the static pressure conditions at both of the sensing port sets are at a known relationship.  As the angle of attack varies from the reference angle, the sensed pressures at the port sets differ, with the difference increasing with increasing angle of attack.  The sensor normally has a pitot pressure opening at its forward extremity, although a separate pitot pressure probe may be used if desired.  A single probe is capable of providing pitot pressure, static pressure and a differential pressure signal proportional to angle of attack.

Abstract: ABSTRACT OF THE DISCLOSURE                 An exposure control circuit that produces a vari-able exposure interval depending upon scene brightness or a constant exposure interval proportional to a predetermined scene brightness, by providing a photocurrent proportional to the level of actual scene brightness and a reference current proportional to the predetermined scene brightness and, preferably automatically, selectively integrating the photo-current or the reference current depending upon the relative magnitude of the currents.  The integrated current provides a signal to produce a variable exposure interval related to actual scene brightness when the photocurrent is greater than the reference current, or provides a signal to produce a con-stat exposure interval when the photocurrent is less than the reference current. The selective integration may be disabled to permit only the photocurrent to be integrated over all scene brightness and thus produce only a variable exposure interval that is related to actual scene brightness.

Abstract: ABSTRACT OF THE DISCLOSURE A motor is driven in stepped fashion by a pulsed alternating output from an integrated co?nter circuit and a source of oscillation to drive a gear train of a clock in stepped increments.  The motor includes a stator having a core with at least one pair of stator poles, a winding coupled to the core, and a rotor having permanently magnetized poles of alternately opposite polarity; while the oscillator includes a highly stable quartz crystal.  The stepping motor is self starting within at least the second pulse applied across the winding and provides a unidirectional drive by provision and arrangement of a pair of extensions, one on each stator pole although on opposite sides, proximate an air gap between stator poles, within which the rotor rotates.  One extension is disposed forwardly into the air gap, while the other extension is disposed rearwardly out of the air gap.  The extensions cause the rotor to reside in a magnetic detent disposition relative to the stator arrangement when no current flows in the stator winding and the stepped or skewed disposition of the extensions at the a r gap influences the rotor to move unidirectionally through stepped increments upon each energization of the winding.

Abstract: ABSTRACT        A method of and apparatus for effecting image reversal development in electrophotography.         Liquid toner is introduced into a chamber containing a latent-image carrying photoconductive surface of an electrophotographic member and a metal plate arranged parallel spaced apart defining two boundaries of the chamber.  A high d.c. bias is applied across the chamber having a value and polarity sufficient to raise the background areas of the latent image to a high charge potential and to reduce the remaining highest charged areas of said latent image to zero.          The intermediately charged areas are reversed in polarity but the relative magnitude of their charges is maintained.          The toner used has polarity opposite of the bias polarity.          When the toning is completed, the bias polarity is reversed on completion of toning to drive particles still floating in the liquid toner to the plate clearing the suspending medium.  The image obtained is the reverse of the "original" latent image.  Apparatus is provided to practise the method described.
