Abstract: Abstract of the Disclosure An offset compensating circuit for cancelling low frequency components generated by drift in an A/D converter upon digestization is disclosed.  The circuit includes a subtractor, a sign decision circuit, a counter and an offset setting circuit.  The incoming signal is fed to the subtractor where it is subjected to subtraction by a signal from the offset setting circuit.  The sign decision circuit receives the output from the subtractor and causes the counter to count up or down depending on the sign of the signal detected.  After a predetermined limit is reached an overflow signal is sent to the offset setting circuit and the counter returns to zero. If the overflow is positive, a positive signal is sent from the offset setting circuit to the subtractor and if the overflow is negative, a negative signal is sent.

Abstract: APPARATUS FOR GAUGING THE TEXTURE OF A CONDUCTING SURFACE                 ABSTRACT OF THE DISCLOSURE          A capacitance gauging apparatus is described for monitoring the texture or flatness of a conductive surface.          Conductive plate members, resiliently supported on a flexible substrate, provide a probe to measure the texture of a surface to be monitored, the surface itself forming the other plate of a capacitor.  The capacitance probe is electrically energized and connected to a monitoring circuit.  As the insulated probe rests on the conducting surface, the resulting capacitance changes the frequency of the monitoring circuit.  The monitoring circuitry counts the pulses within a period, the number of  pulses being proportional to the surface texture, i.e., the higher the number, the coarser the surface texture, and conversely.  The period of counting is set such that the surface texture may be displayed directly in microinches or micrometers.

Abstract: INK JET PRINTER APPARATUS              AND METHOD OF OPERATION              ABSTRACT OF THE DISCLOSURE     In a magnetic ink jet printer a continuous stream of ferrofluid ink drops is projected toward a print medium.  A magnetic selector located proximate the stream is operated in synchronism with the flight of the ink drops for deflect-ing individual unwanted ink drops into a drop catcher.  Due to fringing effects produced by the selector when unwanted drops are selected, adjacent print drops are deflected a lesser amount from the initial stream trajectory.  Print drops not affected by the fringe magnetic field produced to select unwanted drops are subjected to a compensation deflection depending on their position relative to the unwanted drops so that all print drops follow the same trajectory, after passing the magnetic selector in their travel through a vertical deflector and deposition onto the print medium.
