Abstract: Abstract of the Disclosure A scintillation camera system includes compensated delay line clipping circuitry for eliminating base line under-shoot and a restoring circuit for minimizing base line restora-tion of a data signal.  The compensated circuitry includes a single delay line circuit for clipping an incoming data pulse having a relatively long trailing edge.  A variable resistor is coupled with the circuit for controlling amplitude and polarity of the unclipped, incoming data pulse.  A value of this unclipped pulse is controllably summed with the clipped pulse for correcting delay line attenuation and base line under-shoot.  The restoring circuit is combined with the single delay line clipping circuit for restoring the base line of the single delay line clipped pulses.  The restoring circuit produces double delay line clipped timing pulses from the single delay line clipped waveform pulses.  The circuit includes a restoring gate connecting a data line coupling capacitor to circuit ground.          The gate is responsive to the double delay line clipped timing pulses for allowing selective discharging of the coupling capacitor in anticipation of a data pulse for maintaining the base line of the data pulse.

Abstract: APPARATUS AND PROCESS FOR DRILLING UNDERGROUND ARCUATE PATHS UTILIZING DIRECTIONAL DRILL AND           FOLLOWING LINER         Abstract of the Disclosure A motor-powered directional drill is ad-vanced in an inverted arcuate path underneath an obstacle such as a water course.  A second concentric and larger lining pipe follows the advance of the directional drill either simul-taneously but preferably sequentially to form a concentric annulus about the directional drill.          This lining pipe preserves the directional drilling path made and prevents the collapse or the erosion of the hole due to manipulation of the directional drill.  When the inverted path underneath the obstacle is completed and the liner extends the full length, the liner becomes a large diameter pipe of improved tortional capability which can be used sub-sequently to ream the hole to full size for placement of a production casing.  A specialized drilling rig is provided having one advancing chuck for crowding the directional drill into the ground and another larger rotating chuck to rotate and advance the following lining pipe into the ground concentrically about the directional drill.

Abstract: ADAPTIVE ANTI-LOCK BRAKE CONTROL APPARATUS          Abstract of the Disclosure An anti-lock brake control especially suited to heavy duty trucks with air brakes senses the wheel speeds on a given axle and cyclically releases and applies the brakes on that axle as required to avoid undesirable wheel slip during braking. In one control channel, a deceleration switch responsive to a wheel speed signal produces a brake release signal when wheel decelera-tion exceeds a predetermined threshold.  A second parallel channel, also responsive to wheel speed, derives a velocity error signal representing the difference between wheel speed and an estimated vehicle speed and produces a release signal when the velocity error exceeds a value which varies as a function of wheel speed.  The velocity error is determined by comparing the wheel deceleration with an estimated vehicle deceleration and integrating the difference.  The second channel also includes an acceleration switch connected to the release integrator to quickly remove the velocity error signal when a predetermined wheel acceleration occurs to effect brake reapplication.  A self-check circuit includes a timer producing an output signal which increases with time and a synchronous reapply circuit connected to the second channel to effect brake reapplication when a time period has expired.  The timer is operative when a self-check accelerometer indicates that the wheels experienc-low positive or negative acceleration and when a self-check logic circuit indicates that the control circuit calls for a brake release.  A comparator and latch circuit responsive to the timer output signal is actuated when a second larger time period has expired and is effective to illuminate a warning lamp and to disable the control circuit.  The timer is retarded when a large velocity error signal is present to extend the time periods for brake reapplication and disabling of the circuit.
