Abstract: ABSTRACT        In a time-division multiplexing system, data are supplied to the multiplexer with different speeds.  Depending on the speed, time slot groups are allocated to the data, with the number of allocated time slots increasing with the speed.  The search for groups of free time slots occurs in a fixed sequence.          Data to which time slot groups at the end of the fixed sequence have been allocated, are relocated to time slot groups which have become free nearer the beginning of the sequence.  The allocated time slot group for the forward transmission direction is signalled to the multiplexer of the remote station which in turn occasions a corresponding allocation of time slots for the reverse transmission direction for data originating at the remote station.

Abstract: Abstract of the Disclosure A system for providing remote locations with processed data relating to weather conditions or the like. A transmitter adapted to receive complex, real-time radar data, including azimuth, range and elevation. From the National Weather Bureau (NWB) radar network is used to process the data into a four-range radar image and to append geographic overlay information for transmission over voice grade phone lines to remote receivers. In the receivers, the data from the phone lines is converted by a demodulator into digital data and stored into predetermined memory locations corresponding to the four-range categories from which the radar data had originally been acquired. Once stored, any one of the ranges can be individually and instantaneously selected for display in a six-color format representing six predetermined precipitation intensity levels established by the NWB.

Abstract: Method and Apparatus for Pipe Inspection Abstract A mounting system for maintaining a transducer in contact with a pipe during testing.  The system is mounted to a frame which is in turn mounted for movement along a length of pipe.  A first step in the testing procedure is to position the frame a distance away from the pipe dependent on the pipe diameter. A carriage coupled to the frame is then lowered to a scanning position and scanning takes place as the frame is moved along the pipe.  A universal joint mechanism connecting the carriage to the transducer allows up and down and side to side movement of the transducer and thereby allows scanning to continue on pipes with bows and other irregularities along their length.     When the pipe end is neared the carriage is re-tracted away fom the pipe by action of a spring mechan-ism.  In this retracted position downward movement of the transducer is prevented by a ball support coupled to the transducer and contacting a supporting surface of the carriage.  In this way the transducer will not fall from the pipe's end nor collide with the end so that damage to both transducer and mount are avoided.

Abstract: ABSTRACT     A circuit, including a dual-Mode amplifier, for pro-ducing a controlled current through an inductance; in par-ticular, the inductive yoke of a cathode-ray tube electro-magnetic deflection system. A diode coupled to a fly-back capacitor operates automatically to connect the capacitor in parallel resonant connection with the yoke whenever the voltage induced in the yoke exceeds a predetermined value, thereby switching the circuit from a linear mode to a non-linear mode. In a repetitive beam-sweeping environment, the circuit operates in the linear mode during forward scan  time and in the non-linear mode during reverse re-trace   time. In the more general case, the circuit switch-es from linear operation to non-linear operation whenever the rate of change of a single input signal exceeds a pre-determined design rate.
