Abstract: ABSTRACT OF THE DISCLOSURE Apparatus is provided which is responsive to a video signal for producing a position-modulated pulse train which is representative of the occurrence of transitions of the video signal.  A transversal filter is responsive to the video signal and produces a differentiated replica of the video signal over a given band of frequencies.  The output of the transversal filter contains transitional information of the video signal occupying a range of frequencies which is to be analyzed. Information representing transitions of positive, negative, or both polarities is then compared to a given threshold value.  Signal transitions exceeding the threshold are converted to pulses, thereby producing a train of pulses representing significant transitions of a desired polarity or polarities.  The times of occurrence of the pulses are then analyzed to generate a control signal for controlling a given characteristic of the video signal during processing.

Abstract: PHN. 10.069                    13 ABSTRACT:         NTSC-colour television coding circuit comprising a series arrangement formed by a colour difference signal matrix circuit, a I-signal and .OMEGA.-signal matrix circuit, two low-pass filters, a modulator circuit and a super-position stage for supplying a quadrature-modulated chrom-inance signal.  In order to obtain the chrominance sub-carrier burst in the chrominance signal, a burst-gate signal the pulse leading edge of which is produced before the beginning of the burst, is added to the -(B-Y) colour difference signal.  The chrominance signal in which the prolonged burst is distorted at the beginning by the filter is applied to a signal blanking circuit in which the dis-torted beginning is blanked and the burst in accordance with the standard is present in the chrominance signal obtained.  Now, the burst amplitude can be adjusted, without a phase shift, by means of one potentiometer.

Abstract: METHOD AND ARRANGEMENT FOR SIGNALING THE TRANSMISSION MODE OF A COMMUNICATION SYSTEM            Abstract A communication system signaling method and arrangement utilizing direct current signaling over the line loop connecting a line terminal to a central office. The direct current provides concurrent active/inactive line terminal condition signaling and analog/digital information transmission mode. signaling between the terminal and central office.  A current flow in a first direction over the line loop signals the analog mode, while a current flow in the opposite direction signals the digital mode.  A change in the operating mode is signalled by blocking current flow at the line terminal.  The resulting interruption of current flow is detected at the central office which responds by reversing the direction of current flow over the line loop.  Current flow in the line loop indicates the active (off-hook) condition of the line terminal, while the absence of current flow for a predetermined interval indicates the inactive (on-hook) condition.

Abstract: ABSTRACT OF THE DISCLOSURE     An incident light image is projected onto a CCD device through a colour filter array.  The colour filter array has rows of colour filter blocks in a repeating pattern  with a repeat of at least four rows, the filter blocks overlying rows of sensors alternate ones of which are read out during an interlaced scan.  All of the colour filter rows forming the colour filter array have an arrangement of colour filter blocks with two different colour transmission characteristics alternately arranged, and are arranged so that not only is there a horizontal offset between successively scanned but physically alter-nated rows such as to enable separate colour signals to be derived from a multiplex signal provided by the scanning, but also successive interlaced scanning fields will provide similar multiplexed signals.  Embodiments are described in which this is achieved in arrangements in which the outputs of physically adjacent sensor rows are averaged by charge coupled devices.

Abstract: ABSTRACT: Frequency synthesiser.           A frequency synthesiser of the type employing a cycle cancellation technique and providing a correction signal which at least reduces the jitter in the output frequency caused by each cancelled cycle. A control device (CD) causes cycles to be added (PA) and cancelled (PS) without affecting the average frequency (Fc). A compen-sation signal for the resultant jitter is also generated (DAC and I) which is combined with the correction signal in an adder (AS) and with the frequency control voltage signal from the phase comparator (PC) in a further adder (ASD). These added/cancelled pulses cause any residual discrete spurious signal, resulting from the system imbalance, to be spread over a wide spectrum to appear as noise at a very low level. Also the settling time of the synthesiser after a frequency change is increased in some types of synthesiser.

Abstract: A digital TV receiver includes an A/D converter circuit for converting an analog video signal to a digital video signal, a signal separator circuit for separating a digital chroma signal and a digital Y signal from the digital video signal, a colour killer circuit for gating the digital chroma signal to generate a gated C signal when burst components are containing in the digital chroma signal, and a processor circuit for digitally composing RGB signals from the digital Y signal and the gated C signal. The RGB signals are used as tricolour signals for a colour CRT. The digital Y signal is obtained by subtracting the digital chroma signal from the digital video signal, this subtraction being disabled by a signal from the colour killer circuit when burst components are absent, so as to avoid unnecessary degradation of the Y signal when the colour killer is operative.

Abstract: ABSTRACT OF THE DISCLOSURE      A setting tool is shown of the type adapted to be made  up  in  a  pipe  string  for  releasably  engaging  a setting sleeve in a well bore.  The setting tool has a mandrel having an upper end adapted to be connected in the pipe string and having a lower end.  A setting nut is carried on the mandrel having external connecting threads for engaging mating connecting threads located on the interior of a setting sleeve disposed about the lower end of the mandrel.  The mandrel is slidably disposed within the setting nut when the setting nut is engaging the setting sleeve and the mandrel is slidable between an extended  running-in  position  and  a  weight  set-down position.      A latch collar having at least one latch ear is carried on the mandrel exterior.  The setting sleeve has at least one end notch adapted to receive the latch ear for preventing relative rotational movement between the connecting threads of the setting nut and the setting sleeve when the mandrel is in the extended running-in position  and  allowing  relative  movement  between  the connecting threads when the mandrel is in the weight-down position  to  release  the  connecting  threads.   Torque override is provided for releasing the latch mechanism upon the application of a predetermined rotational torque to  the mandrel  to  thereby  allow  relative  rotational movement  between  the  connecting  threads  without  the application  of  downward  force  to  the  mandrel.   The mandrel  is  spring  biased  in  the  extended  running-in position  and connected  by  a  shear  mechanism  to  the setting sleeve to prevent inadvertent release of the tool during the running in operations.
