摘要： An apparatus and method is provided for a less costly and more reliable latchtacking technique that produces a finished work piece that is esthetically superior to the work piece that is produced by the current technique. A chain cutter has miniaturized cutting blades located at the back edge of the chaining tongue such that a relatively short unstretched chain is cut. The chain is not stretched because, stitch Also at the time the chain is cut, the vacuum in the hollow chaining tongue has been turned off. The tension on the needle thread is adjusted when chaining begins such that a short pliable balanced chain is produced which results in a more reliable technique and a latchtack that is esthetically superior to prior art latchtacks.

摘要： A diskette read data recovery system generates a clock which is locked to an incoming data stream. In a phase locked loop, a signal generated by an oscillator and frequency dividers is compared in phase to the incoming data stream to provide first or second signals depending on whether the incoming data signal leads or lags the clock signal. In order that the system may handle different types of incoming signals, different frequency divider circuits in the phase locked loop are selected for different incoming signals.
