Latest Patents
One of his notable inventions is an apparatus for counting turns when making threaded joints. This device includes a high-resolution turns counter that senses the rotation of a joint member and generates a pulsed signal for each predetermined increment of rotation. The turns counter utilizes an idler wheel driven by one member of the joint, which in turn drives an encoder to produce a large number of pulses per revolution. A presettable divide-by-N circuit is employed to divide the encoder pulses, generating a pulse train for monitoring and control purposes. This innovation ensures the quality of the joint by indicating whether a good or bad joint has been made.
Another significant patent by Hall is an apparatus for making threaded joints that incorporates a make-up speed control. This invention regulates the speed of rotation of a joint member during the threading process. At lower speeds, a counter receives clock pulses and counts down from a stored value to manage the maximum rate of turn signal pulses generated. If the elapsed time between pulses is less than or equal to the stored time, a signal is generated to slow down the operation. At higher speeds, the counter monitors the total number of turn signal pulses to ensure they do not exceed the maximum allowed in a predetermined time interval.
