    • Disclosed is a method for determining the sound velocity (Cb) in a basic material, in which an ultrasonic probe having a transmitting probe, a receiver transducer, and a forward member is used. The forward member is provided with a coupling surface that couples the probe to the basic material, and has a sound velocity (Cv). The transmitting probe and the receiver transducer are aligned in an oblique manner from each other and from the coupling surface such that a main transmission direction of the transmitting probe and a main receiving direction of the receiver transducer intersect below the coupling surface. The centers of the transmitting probe and the receiver transducer are located at a distance K from each other and are located at a distance Dv from the coupling surface. According to the inventive method, the transmitting probe generates an ultrasonic pulse which runs through the forward member into the basic material, where the ultrasonic pulse creates a creeping wave, a portion of which arrives at the receiver transducer. The shortest sound traveling time (Ttot) is measured and the sound velocity (Cb) within the basic material is determined via the path between the transmitting probe and the receiver transducer, which supplies the shortest total traveling time (Ttot).

    • In order to increase the speed at which a workpiece is tested by the ultrasonic pulse-echo method, the dead time between individual measurement time intervals is shortened by providing a minimum predetermined time interval selected for the specific test conditions. When an echo responsive signal is manifest in the receiving circuit, in order to prevent the occurrence of phantom echo signals arising in the following measuring interval, the generation of the succeeding transmit signal is inhibited for the predetermined time interval after receipt of the last echo responsive electrical signal of the measuring interval having an amplitude exceeding a predetermined minimum amplitude. The test speed therefore, is made adaptive to the condition of the receipt of the number of echo responsive electrical signals exceeding a predetermined minimum amplitude.
    • 为了通过超声波脉冲 - 回波法提高工件的测试速度,通过提供针对具体测试条件选择的最小预定时间间隔来缩短各个测量时间间隔之间的死区时间。 当在接收电路中显示回波响应信号时,为了防止在随后的测量间隔中出现幻像回波信号的发生,在接收到最后一个回波响应之后,预定时间间隔的生成被抑制 测量间隔的电信号具有超过预定最小振幅的振幅。 因此,测试速度适应于接收超过预定最小振幅的回波响应电信号的数量的条件。

    • The invention relates to an ultrasonic test instrument, in which a receiver amplifier is controlled in dependence upon time by means of a depth compensation signal or else the ultrasonic signal amplified independently of the depth is evaluated by means of a time-dependent variable threshold signal. The depth compensation signals and the time-dependent threshold signals are derived from the same digital signal values stored in a main memory. The test instrument comprises a microprocessor by means of which the digital signal values for each material requiring testing are automatically measured by the instrument itself in conjunction with whichever test probe is used provided a corresponding test block of this material is available. The microprocessor also controls the circuit generating the depth compensation and threshold signals, so that depending upon the type of operation selected the cathode ray tube can display either the ultrasonic echo responsive signals corrected as a function of depth or the uncorrected ultrasonic signals are shown together with the time-dependent threshold value.

    • Display of the results of non-destructive testing with a beam of ultrasonic energy is enhanced by exercising precise control over the horizontal sweep voltage which is applied to the deflection plates of a cathode ray tube on which the test information is displayed. The sweep voltage generator produces a sawtooth waveform which has a precisely selectable slope. The sawtooth voltage waveform slope may be adjusted by selecting the capacitance, which is charged from an adjustable constant current source, and by varying the charging current. A microprocessor, which stores information commensurate with various waveform slopes, will control the adjustment of the sawtooth waveform slope by comparison of the stored information with keyboard entered data corresponding to a desired slope.

    • A method and apparatus are provided for converting into digital form the analog ultrasonic echo signals received as a result of cyclically transmitted ultrasonic search signals intercepting an acoustic discontinuity in a workpiece. The ultrasonic echo signals are divided into a discrete number of raster-like scan lines which are scanned electronically by a microprocessor. Digital signals are generated for each line of the raster-like scan and such signals assume either a first or second state along the scan line in accordance with the signal amplitude along that line. As successive scans are made at progressively higher amplitudes of the echo signal, the amplitude required for varying the digital signal between the states for a particular scan line is incrementally increased with each scan line. A comparator receives at a first input the echo signals and at a second input a signal from a digital-to-analog converter whose output is incrementally increased on successive scan lines by the microprocessor. The outputs of the comparator are placed into storage in the microprocessor.

    • An ultrasonic test instrument includes a pulse generator, a receiver, a cathode ray tube screen display and a time gate means providing a gated time interval for viewing only echo signals which arise from a predetermined workpiece region under test. The time gated interval is shown as a horizontal gate bar display on the screen and the length of the bar being indicative of the gated time interval. Circuitry provided generates a reference signal to cause the gate bar to appear at a height commensurate with the echo signal received in the gated intervals having the highest peak amplitude. Unless reset, the amplitude of the gate bar remains at this peak value although subsequent echo signals may have a lower amplitude.
