Abstract: Abstract Digital Television System and Method"          A method and apparatus for digital television video signals allows recorded information to be replayed by a helical scan apparatus of either the segmental or non-segmental type at a speed different to that at which the information was recorded.  The information relating to each line of video is provided with codes identifying both the individual line and the field.  The line information is used in a storage process for providing either the write or read addresses of the information to allow a picture to be reconstructed.        The apparatus can also be used as a synchron-iser for two broadcast programmes in which case the speed of information in and out will be the same, but the storage process is used to provide an elastic delay.

Abstract: ABSTRACT OF DISCLOSURE         Quasi  periodic  pulse trains  are  generated  and swept in  repetition frequency  over an  octave.  Spectral harmonics of  the pulse  trains which  prevent the  trains from having  a constant  or "flat"  power spectrum  over a frequency range much greater than an octave are reduced or eliminated by  adjusting the  shape of  the pulses  in the trains   By means  of selecting the timing  of the pulses, other harmonics  are reduced or  preferentially augmented. The spectral  energy of  the signals  which are  generated during  a  transmission  interval is  of  the  type  which possesses an  autocorrelation function with a  narrow main lobe and low side lobe levels which is especially suitable for  echo   location  purposes  such  as   in geophysical exploration in which seismograms  are constructed by cross correlation  of the  signals  which  are transmitted  with those which  are received  from the  geological reflection surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE         A glass-ceramic cooktop surface is provided with a temperature sensor integral with the glass ceramic plate of the cooktop.  The temperature sensor utilizes the temperature resistance characteristic of the glass ceramic plate as a means of monitoring the temperature of the plate and is formed in the heated areas of the glass-ceramic plate.  The sensor comprises pairs of metallized conductive strips fired to the underside of the plate and terminated in a cool region of the plate.  A continuity resistor is provided at the termination point of each pair of strips to distinguish between cold glass conditions and a defective sensor.          One strip of each pair is connected to a further metallized strip which surrounds the periphery of the glass and forms a common ground for a heating unit control circuit and is also used as a broken glass detector.  Each sensor forms one leg of an AC voltage divider and is connected to an assoicated control c circuit.  The output of the voltage divider is applied to two voltage comparators having a common output connected to operate a relay to control heater power to the "burners" of the cooktop which may be open coil heaters or film heaters.

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of varistor disks, each having one face thereof coated substantially entirely with electrode material and another face thereof coated with spaced-apart electrode material, such as in two semi-circular patches, are joined together so that said faces coated with a single electrode are coincident.  This configuration reduces by a factor of two the over-all area required for equal current density as compared with certain prior varistor configurations.  The varistor of the present invention also exhibits a lower diameter-to-thickness ratio and hence provides a significantly stronger mechanical structure.  Additionally, the varistors of the present configuration may be readily provided with grooves between electrode surfaces so as to increase the interelectrode spacing, without significantly reducing the mechanical strength of the device.  The invention of the present structure also permits flexible lead configurations.
