  • Publication number: 20230304946
    Abstract: An x-ray inspection system comprising an x-ray source, an x-ray detector, a sample support comprising a pliable material and a sample support positioning assembly configured to position the sample support between the x-ray source and the x-ray detector. The sample support is configured to removably clamp a sample for inspection in a fixed position with respect to the sample support and configured so that, in use, at least one surface of the sample is in contact with the pliable material. The sample support positioning assembly comprises a rotational drive configured to rotate the sample support about a rotational axis. This allows the sample to be rotated about a rotational axis such that a series of two-dimensional images can be captured by the x-ray detector that can be used to create a three-dimensional reconstruction of the sample.

  • Patent number: 11342090
    Abstract: An ionizing radiation shielding panel comprising a core layer, a first layer on a first side of the core layer and a second layer on a second side of the core layer, opposite to the first side. The core layer comprises radiation attenuation material which may be particles of barite. The first and second layers each comprise a permeable reinforcement structure and each of the first, second and core layers are permeated with a binder. In the construction of the panel, the binder is infected into a mould containing the other constituents of the panel. The ionizing radiation shielding panel can be used in the housing of an x-ray inspection apparatus.

  • Publication number: 20140029236
    Abstract: An imaging system comprising a parabolic reflector having a base and defining a first axis, a light source disposed proximate the base essentially along the first axis, an imaging device comprising a zooming lens having a second axis, the imaging device being disposed in front of the light source along the first axis such that the second axis and the first axis are essentially coincident.

  • Publication number: 20060204753
    Abstract: A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process. The yarn includes discontinuous and, optionally, continuous filaments.
