    • The invention relates to composite materials containing immobilized biological active species.
      A method for the preparation of a composite material containing an immobilized biological active species is disclosed. In carrying out the method a gel precursor containing a particulate biologically active species is applied to a support material and gelled to form a composite material comprising a support material, a permeable gel and, immobilized in the gel a particulate biologicallt active species. The rheological properties of the gel precursor are selected to facilitate the application to the support material. The rheological properties are also selected to facilitate retention of the gel precursor on the support material prior to and during the gelling, and/or to inhibit the sedimentation of biologically active species prior to, and during gelling. At least some of the permeable gel is enmeshed with the support material.

    • A method of non-destructive testing wherein ultrasonic signals from a transducer are converted into television wave form and stored on video recording magnetic tape for reproduction as required. Because the signals are recorded live rather than in the form of a cathode ray oscilloscope display they can be rectified as necessary. Positional co-ordinates of the transducer may be stored so that B-scans at varying thresholds can be reproduced. Position and ultrasonic signals are interleaved on the video recording magnetic tape. Apparatus for performing the method includes a video recording device having a rotatable head and interface units for converting the radio frequency signals into television wave form and for decoding the signals for reproduction.
    • 一种非破坏性测试的方法,其中来自换能器的超声信号被转换成电视波形并存储在视频记录磁带上以便根据需要进行再现。 因为这些信号是以阴极射线示波器显示的方式进行录制的,所以可以根据需要进行校正。 可以存储换能器的位置坐标,使得可以再现不同阈值的B扫描。 位置和超声信号交错在录像磁带上。 用于执行该方法的装置包括具有可旋转头部和接口单元的视频记录装置,用于将射频信号转换为电视波形并用于对用于再现的信号进行解码。
