Patent CA-1127238-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         In electrical geophysical prospecting and in well-logging, in which potential is applied to the earth to cause direct current (or low frequency alternating current) to flow between spaced elec-trodes and the potential is measured between other electrodes contacting the earth, difficulties are experienced due to the electrode chemistry at the electrode contacts with the earth.  This phenomenon is usually called polarization, with spontaneous, usually varying potential being generated at the electrode contact.  I have found it possible to use pairs of relatively closely spaced solid conductor electrodes instead of the individual electrodes form-erly used, applying an alternating voltage between the two electrodes of each pair which minimizes polarization, and coupling the direct or low fre-quency A.C. potential between two such pairs either in applying a measuring current to the earth or in determining the resultant potential between other similarly arranged pairs of solid conductor elec-trodes in contact with the earth and also biased with alternating voltage.  The alternating bias current is at least of the order of magnitude and perferably somewhat greater than the direct current in an elec-trode.

Abstract: - 20 -                RCA 72,784 Abstract of the Disclosure An overload detector is provided for generating an overload signal whenever an I.F. signal exceeds a predetermined level.  The overload detector has an input coupled to the emitter circuit of a common emitter transistor of a television I.F. amplifier   When the peaks of the I.F. signal applied to the overload detector exceed the predetermined level, a transistor in the overload detector begins to operate as a class C amplifier, thereby generating a periodic overload signal.  The overload signal is applied to the input of the R.F. AGC circuit of the AGC system to reduce the gain of the R.F. amplifier of the television receiver.  The gain of the I.F. amplifier is not affected by the overload signal, and thus there is no degradation in the signal-to-noise performance of the I.F. amplifier.

Abstract: Abstract of the invention A between-lens shutter assembly for photo-graphing devices comprising at least two, preferably three rotary plates with axes parallel to the axis of the lenses.  Each plate comprises an opening.  When the plates are rotated with common speed, the openings move from evenly distributed directions towards the inside opening of the lenses, completely uncover it, then in continued movement close the inside opening again.  This way identical opening and closing charac-teristics and times are provided.      In a method using the shutter assembly exposures are taken from television pictures, in which the length of the exposure period is adjusted to be equal to the period of a television picture and the duration of either an opening or closing section, whereby uniform illumination is ensured for the exposure.      The invention can be used mainly for the precise photographing of X-ray pictures displayed on the screen of a television monitor.

Abstract: 667-A TITLE RECEPTACLE APPARATUS FOR HOUSING COMPONENTS OF A LIGHTING SYSTEM Components of a lighting system, exemplified by the lighting system utilized in commercial transport vehicles are protectively housed in a receptacle apparatus comprising an enclosure body, open at one side, a closure or cover member arranged to extend into the open side of the enclosure body and O-ring sealing means, retained in an annular channel in the enclosure body, for detachably securing the enclosure body and closure member in sealed relationship. The closure member is constructed at one end with an outer tapered cylindrical flange, a portion of which is located in abutting relation to a circular end wall extending around the open side of the enclosure body. This arrangement defines a prying aperture in which a tool such as a screw driver may be inserted to pry off the closure member when desired. The closure member is characterized by a tubular extension formed integrally with the tapered cylindrical flange and arranged to project inwardly through the opening in the enclosure body in predetermined spaced relation thereto. The tubular extension is further characterized by an extended annular sealing area and a retaining shoulder which is operable to compressibly force the O-ring in displaced relationship along the extended sealing area when the tubular extension and enclosure are in the predetermined spaced relationship noted.

Abstract: Abstract Semiconductor devices can be fabricated using as an intermediate manufacturing structure a substrate of one semiconductor with a thin epitaxial surface layer of a different semiconductor with properties such that the semiconductors each have different solubilities with respect to a metal.  When a vertical differentiation is used to expose the different materials and the metal is deposited on both and heated, the metal will form a Schottky barrier in one material and an ohmic contact in the other.  Where the substrate is gallium arsenide and the epitaxial layer is gallium aluminum arsenide and the metal is tin, a self-aligned gallium arsenide MESFET is formed wherein the tin forms ohmic contacts with the gallium arsenide and a Schottky barrier contact with the gallium aluminum arsenide.

Abstract: AUTOMATIC CIRCUIT AND METHOD FOR EDITING        COMMERCIAL MESSAGES FROM TELEVISION SIGNALS                  Abstract of the Disclosure In order to delete commercial messages during the viewing and/or video tape recording of broadcast television signals a control circuit is disclosed for producing a commercial editing control signal at the beginning of one or more television commercial messages, which signal continues for the duration of such messages and terminates after the end of the last of such messages The control circuit incorporates detection circuitry for automatically detecting each of series of fade breaks in the video and audio components of the television signal, wherein such fade breaks normally mark the beginning and end of each of one or more commercial messages that have been inserted in the program content. The first of a series of detected fade breaks marks the beginning of a single commercial or the first commercial in a consecutive block of commercials, and succeeding fade breaks occur at time intervals that correspond to the durations of the commercial messages.  Cooperating with the circuitry for detecting the series of fade breaks, is electrical timing circuitry which is triggered to cause the generation of the above-mentioned editing control signal The timing circuitry has a time out interval that is selected to be just slightly longer than the maximum anticipated length of each of the consecutive commercial messages, and is retriggered each time another fade break is detected.  A steady control signal is thus generated which continues until the timing circuitry is allowed to time out because of the absence of detected fade breaks, indicating the resumption of non-commercial program content. In the form of the control circuitry disclosed herein, the automatically generated control signal is used to operate a pause control on a video tape recorder for momentarily stopping the recorder during the occurrence of one or more consecutive commercial messages.

All tracks in a respective track set are sensed for play-back by a movable reading head incorporating a combination of video and audio sensing elements and including tracking of homing elements flanking the video reading element.  A track set switching signal is sensed from the audio signal by an audio reading element for a controller means which very quickly slews the reading head to roughly position the video reading element for next video track.  Such video track is sensed by any reading element in the reading head and determined through a multiplexer and controller means.          Reading head is further stepped as necessary until video track sensing element is reading video track as controller receives video signal through band pass filter video sensing element.  Position adjustment further made by controller, only as necessary, responsive to respective signals by tracking elements.  The entire switching cycle from one video track to next is completed in substantially less time than attainable by any previously known prior art method or apparatus.
