Abstract: ABSTRACT OF THE DISCLOSURE           The present invention involves a method and apparatus to prolong the useful life of a drive tape used in a magnetic contact printer to advance a master and copy tapes past a transcribing head to transcribe the signals on the master tape onto the copy tape. The present invention provides a method for using the entire length of the drive tape even though individual segments on different master tapes may be shorter than the length of the drive tape.  In the method of the present invention the drive tape is rewound after each transcription only part of the way to the beginning of that transcription.  The next transcription will then require the use of a part of the drive tape not used in the previous transcription.  The apparatus of the present invention uses a digital logic circuit to carry out that method. The apparatus comprises a counter that senses the length of advance of the drive tape for each transcription and detectors that provide signals to terminate the rewindings of the drive tape at the proper points.

Abstract: Abstract Tracing and identifying electrical conductors in a power distribution network is achieved by use of a transmitter operating on a duty cycle of absorbing current pulses at a predetermined frequency from the power distribution network, and by use of a remotely located receiver which detects the electromagnetic field signals resulting from the current pulses in a predeterrmined cyclic manner of operation defined by a sample period and a reset period.  During the sample period the receiver supplies an indication of the maximum received strength of the transmitter signal.  The relationship of the duty cycle of the transmitter and the sampling and reset periods of the receiver reduce the potentially adverse influences of spurious signals on the receiver.

Abstract: ABSTRACT OF THE DISCLOSURE     A buckle comprises a male member including a pair of resiliently flexible legs each having an abutment surface, and a female member having a socket portion releasably couplable with said legs and including a pair of spaced sidewalls defining therebetween a slot for receiving therein said legs, each of the sidewalls having a retaining surface engageable with the abutment surface to interlock the male and female members.  The socket portion further has a pair of cantilevered arms disposed inwardly of the sidewalls and resiliently flexible toward and away from the sidewalls.  An actuating lug is disposed on a distal end of each arm which is located outside of the slot, the lug being engageable with one of the legs.  The arms are resiliently flexible toward each other to cause the actuating lugs to urge the legs to flex resiliently toward each other for bringing the abutment surface and the retaining surface out of engagement with one another.  The advance in the art is in that the arms are protected from being damaged or broken when subjected to undue lateral pulling forces tending to spread the arms.
