  • Patent number: 9321134
    Abstract: A clamping device (1) for internally centering pipes with respect to one another includes two clamping heads (5, 6), which can be placed into the mutually facing ends of the pipes. The clamping heads each have radially displaceable clamping shoes (7) which are evenly distributed over its external periphery and a drive mechanism (8) for causing the radial displacements of the clamping shoes. Adjusting piston/cylinder devices (10) are provided for adjusting the mutual positions of the clamping heads in the axial direction and a guide element (11) for guiding the clamping heads in the axial direction with respect to one another. Bearings (13) are provided on at least one (5) of the clamping heads and on the guide element (11). The guide element has several guide bodies (12) which are positioned in an eccentric manner in connection with the stability of the clamping heads.

  • Publication number: 20140328533
    Abstract: A product testing apparatus is described as having one or more imager configured to capture one or more images of a sample having a substrate coating applied to a substrate, a processor in communication with the imager, and a non-transitory processor readable medium, in communication with the processor. The non-transitory processor readable medium stores processor executable instructions that when executed cause the processor to receive the one or more images from the one or more imager. The processor then processes the one or more image by filtering lighting variations in the pixels of the one or more images to identify one or more objects of interest in the one or more images of the cured/uncured substrate coating. The processor quantifies one or more property of the one or more objects of interest. The processor executable instructions then cause the processor to generate one or more signal indicative of the quantification of the one or more objects of interest.
