Patent number: 4074332Abstract: A digital circuit and method for measuring magnetic tape skew of magnetic tape units by recording on two channels of a reference tape a digital bit pattern of alternate pairs of zeros and ones.Digital logic circuitry, which detects this information on a reference tape when read from a magnetic tape unit to be tested, feeds the digital information on one channel to a shift register which is sampled by a clocking signal derived from the other channel. The digital bit pattern indicated at the output stages of the shift register will identify the existance of any excessive lag or lead skew.Type: GrantFiled: May 27, 1976Date of Patent: February 14, 1978Assignee: Litton Business Systems, Inc.Inventor: Frank T.

Patent number: 4017789Abstract: A constant potential power supply with current overload protection having a series switching regulator including a series switching circuit controlled by both a Schmitt-trigger circuit controlled by an output voltage detector to maintain the output load voltage within a predetermined range during normal operation and a current overload protection circuit having a foldback characteristic which operates when the output current goes above a predetermined value. The Schmitt-trigger circuit is actuated by a signal from an output voltage detection circuit when the output load potential decreases below a certain value to enable the series switching circuit to conduct current to the load from an input voltage source and is disabled as the output load potential goes above a certain value. After actuation of the series switching circuit and until it is disabled, charging current passes into an integrating capacitor.Type: GrantFiled: April 16, 1975Date of Patent: April 12, 1977Assignee: Litton Business Systems, Inc.Inventor: David Morris
