Abstract: ABSTRACT OF THE DISCLOSURE:         An equipment for recording and reproducing color television signals or VTR (video tape recorder) is combined with a color television receiver as a single unit in such a way that some of their circuits are used in common in both the VTR and receiver, whereupon the circuit design as well as operation may he much simplified.  The VTR and receiver are operatively coupled to each other through a switch for selecting a recording or reproducing mode.  In recording mode, the video signal, which is received and detected by the receiver, passes through the mode selection switch to the luminance signal processing circuit and the carrier chrominance signal processing circuit in the receiver.  The separated luminance and chrominance sig-nals are applied to the input terminal of the VTR so that they may be recorded while one is watching the picture on a picture tube.  In the reproduction mode, the luminance and chrominance signals derived from the output of the VTR are added and applied to the input terminal of the processing circuits in the receiver through the mode selection switch so that they are processed in the signal processing circuits to reproduce the picture en the picture tube.  In one embodiment of the present invention, the luminance and chrominance signals may be applied to their pro-cessing circuits, respectively, in the receiver through another selection switch.  An APC type or a ringing type circuit is used for color synchronization.  In order to minimize the effects caused by the jitter in the VTR, a feedback loop including the reproduction circuit of the VTR is provided.  In the APC        (automatic phase control) circuits, the crystal oscillator and/or LC oscillator are used.

Abstract: METHOD AND APPARATUS FOR HANDLING DUST SEPARATED FROM GASES             Abstract of the Disclosure A continuous system for separating dry dust from gases under superatmospheric pressure and handling separated dust by forming a slurry of the dust with water in a mixing and holding tank with provision for transferring the slurry to slurry thicken-ing apparatus while at the same time maintaining the system gas tight against escape into the ambient atmosphere of the gases from which the dust is separated.  The slurry can be continuously transferred by gravity from the tank, holding the desired back pressure on the tank by a liquid seal; the slurry can be continu-ously transferred from the holding tank through a throttling valve which maintains the desired back pressure on the holding tank; the slurry can be transferred in a batch manner under low superatmos-pheric pressure built up in the holding tank; or the slurry can be transferred under higher gas pressure for long line transmission to a slurry thickener; all with safety arrangements for keeping water out of the dry dust separating apparatus and for preventing the escape of gas.

A number of such shadowgraphs are obtained for different angles of rotation of the fan-shaped beam relative to the center of the slice being analyzed.  The detected fan beam shadowgraph data is reordered into shadowgraph data correspond ing to sets of parallel paths of radiation through the body.       The reordered parallel path shadowgraph data is then convoluted in accordance with a 3-D reconstruction method by convolution in a computer to derive a 3-D reconstructed tomograph of the body under analysis.  In a preferred embodiment, the position sensitive detector comprises a multiwire detector wherein the wires are arrayed parallel to the direction of the divergent penetrating rays to be detected.  A focused  grid collimator interposed between the body and the position sensitive detector for collimating the penetrating ray to be detected.  The source of penetrating radiation is preferably a monochromatic source.

Abstract: ABSTRACT OF THE DISCLOSURE              An electronic halftoning image reproduction system wherein a halftone screen-function is combined with pictorial information, typically by addition, to provide a sum function.  In a second channel the pictorial signal is averaged over the area corresponding to one period of the halftone screen function and the average is utilized to determine the percent of the area to be turned white within that halftone dot.  This is accomplished by thresholding the sum function with a dynamically adjusted threshold for each period of the halftone dot such that the percentage of white matches the average pictorial signal.  In another embodiment wherein the desired gray scale of the reproduction is different from that of the original image, the average pictorial signal may be adjusted in some predetermined manner and the percentage of white is matched to the adjusted signal.  In a digital im-plementation the result is obtained by starting at the sample location with the largest value of the sum function and setting subdots white until the correct area is white.  All steps are repeated over each period of the halftone.

Granted: 1979-10-09
Abstract: Abstract of the Disclosure A system for monitoring the channel to which a remotely located voltage tunable receiver or converter is tuned includes a comparator for comparing the magnitude of the tuning voltage with an internally generated reference voltage to determine the channel number.  The reference voltage is generated by a counter driving a linear digital-to-analog converter.  The output of the digital-to-analog converter is modified with an analog function generator to provide a piecewise linear approximation of the receiver tuning voltage versus channel number characteristic.  A window comparator is utilized to compare the output of the function generator with the tuning voltage and to stop the counter and transfer the contents of the counter to an output circuit when the magnitude of the reference voltage approaches that of the tuning voltage.  The contents of the counter at the time the counter is interrupted is indicative of the channel number of the station being received.

Abstract: ABSTRACT OF THE DISCLOSURE        This disclosure depicts an electron gun for use in a color cathode ray tube of a small neck, shadow mask type.  The gun includes an extended field lens for generating a cluster of electron beams converged and individually focused at the screen of the tube.  Three main focus lens means are situated on lens axis which are mutually parallel and parallel to a gun central axis.  At least two of the lens axes are off-axis with respect to the gun axis.  The focus lens means has for each beam at least three electrodes including a focus electrode for receiving a  potential for electrically adjusting the focus of the beam.  In succession down-beam, there at least two associated electrodes having potentials thereon which form in the gaps between adjacent electrodes significant main focus field components.  To adjust beam focus, the strength of a first of these components is controlled by the voltage received by the focus electrode.  The strength of a second of the field components is relatively less than that of the first component.  Each of the lens means is character-ized by having addressing faces of the associated electrodes which define the second field component being so structured and disposed as to cause the second field component to be asymmetrical and effective to significantly divert the beam from its path resulting in convergence of the beams without any significant distortion of the beams and substantially indepen-dently of any beam-focusing adjustments of the first field component.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides for a better utilization of the residual heat contained in a flue gas of a central hot water heating system.  This is achieved by means of a valve, which, as a function of the outlet temperature of the flue gas, can switch on or off at least a part of the heat exchanger of the system.  This valve is controlled by a temperature feeler gauge installed in the flue-gas pipe of the system.  The feeler gauge acts as a control element itself or it controls the position of the valve by way of a servomotor when the outlet temperature of the heating gas reaches the value only slightly above the predetermined value.
