摘要： In the process whereby a time gate but especially the time gate for an expected error range 58 in a device by means of which materials are tested by ultra sound according to the impulse echo process involving a test head 20 which emits pulses that impinge diagonally on the surface 28 of a test piece 24, the test head 20 that emits diagonally is firmly connected to a test head 22 from which pulses are emitted vertically. Both test heads emit at given intervals 48, 49 ultra sound impulses and subsequently receive them. The echo signal 50 of the entry of sound of the test head 22 from which pulses emit vertically is utilized to activate the time gate of the test head from which sound is emitted diagonally.

摘要： A method for processing digitized ultrasonic signals originating from an ultrasonic probe for the storage and later reconstruction of the ultrasonic signals from the stored data. Each half-wave from the digitized data is stored as the maximum amplitude, polarity sign, and location on the time axis of the wave. Reconstruction of the signal from the stored data is effected by constructing a series of 180.degree. cosine curves from the stored data and connecting each successive cosine curve with the previous cosine curve.
