Abstract: A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt.

Abstract: An electronic intelligent indenter system that determines the hardness and the case depth of a hardened portion of a test part in a non-destructive manner. The system employs an electronic indenter tool having a tip. To determine the depth of the case hardened portion of the part, the indenter tip is placed in contact with the surface of the part, and a laser emits a laser beam pulse that impinges the surface of the part proximate the tip. The laser beam generates ultrasonic waves that propagate into the part. The ultrasonic waves reflect off of a transition between the case hardened portion and an unhardened portion of the part. A detector in the indenter system detects the reflected ultrasonic waves. The ultrasonic waves cause the detector to generate a signal identifying the time between when the laser pulse is emitted and when the reflected wave is received.
