摘要： The high voltage terminal of the ultor capacitance of a cathode ray tube is coupled to an electron gun structure. The ultor return terminal which typically comprises an outer conductive coating of the cathode ray tube envelope is coupled to the ground return base pin of the cathode ray tube. The ground termination for electrical components and the chassis is also coupled to the ground return base pin. During arc-over, the cathode ray tube ultor capacitance discharges through the ground return base pin. Arc-over current oscillations flow in the chassis and electrical component circuitry by means of stray capacitive coupling to the ultor return terminal. A resistor is coupled to the chassis and to the ultor return terminal for damping arc-over current oscillation in the chassis and in the component circuitry.

摘要： An ignition system includes an alternating current power source which feeds a transformer having a primary winding, the primary winding being coupled to an electronic switch. The electronic switch intermittently interrupts current flowing in the primary winding and in the output circuit of the power source. Such electronic switch is made operable by virtue of the peak excursions of the alternating current thus supplying the necessary collector potential to such switch during each firing cycle of the system. A capacitor in series with the output circuit of the power source and with the primary winding enables current to be transferred out of the power source to such primary winding. Such electronic switch also provides discrete separation between successive output waveforms of successive ignition firing cycles. The system has appropriate logic circuits which initiate current conduction through the electronic switch and in the oscillator stages of the power source for each firing cycle, turning off the switch and oscillator stages between firing periods. Various types of trigger timing circuits are usable to trigger the several logic circuits for initiating igniter firing by means of the resultant high voltage and high current in the secondary winding of the transformer.

摘要： Monolithic acoustoelectric signal storage device and means for generating a surface acoustic wave on piezoelectric material and propagating the wave into a storage region of the device. An electric field applied across a storage structure in the storage region of the device interacts with the electric field associated with the surface acoustic wave to produce a holographic replica of the wave in a spatially varying distribution of charge trapped at a solid dielectric-dielectric interface. The stored waveform may then be read out at a later time or, in nonlinear signal processing applications, the electric field of a subsequently generated surface acoustic wave may be propagated into the storage region to interact with the trapped charge to produce an output signal.

摘要： An x-ray beam is transmitted through an object under study and through an encoding grating structure consisting of alternate stripes of materials each having different x-ray absorption characteristics. The recorded image has a grating structure which is modulated by the energy spectrum information represented by the difference of the absorption characteristics of the two stripe materials. The grating amplitude information is decoded by coherent optical filtering or by scanning and used to indicate the presence of specific materials in the object.

摘要： A video frequency amplifier is biased to provide output signals of a first magnitude. In response to the application of a predetermined control signal, the bias is altered so that output signals are provided of a second, different magnitude. When employed in communications systems of the type in which television images are "frozen" by a storage tube for subsequent transmission on an individual frame basis by a voice-quality telephone link, for example, and subsequently re-created, the control signal indicates whether the system and its storage tube are to operate either in the "transmit" or "receive" mode.

摘要： A simplified scanner for facsimile transmission. A cylindrical member supports the material to be scanned and a tubular member extends concentrically into the cylinder. A laser beam passes through the tubular member and is focused to a spot on the inner surface of the cylinder. Either the tubular member or the cylinder is caused to rotate about, and translate along, their common axis with the aid of air bearings. In this manner, spiral scanning is effected with only one moving member. The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention. In order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

摘要： A light beam is generated by means of a narrow band collimated light source, and this light beam is modulated in accordance with an electrical input signal to be identified. The light beam is then optically scanned at a predetermined scanning rate to produce an optical image of the input signals against a time base. Light from this optical image is passed through a holographic reference transparency, which is a spatial filter corresponding to the Fourier transform of the image of known electrical signals, the light passing through the transparency being fed to a detector. Successive reference transparencies are utilized until correlation between the transparency and the input signal to be identified is indicated by a peaking of the detector output which is sensed by a correlation indicator.
