摘要： An easily adjustable and readjustable rail support includes two annularly spaced pot-like members that are separated by a readily meltable solid filler material. The outer member is embedded in a concrete or other rigid roadbed. The rim of the inner member supports a channel element which clamps the rail.

摘要： A readjustable rail fastener includes a channel member fixed in a rigid roadbed, a tapered key member inserted within the channel member, and a rail support member positioned above the key member. The rail is clamped to the rail support member, and after it is positioned in its proper location by means of a jig, it is fixed in position by concrete poured between the three members. The rail is readily relocated by breaking the key member loose, knocking away the old potting concrete, replacing the key member, positioning the rail in its new location, and pouring fresh potting concrete.

摘要： A laminographic instrument for radiographically imaging on a radiation sensitive imaging medium, such as a photographic plate or fluorescent screen, a selected cross-section of a specimen. The instrument includes a novel articulated support forming a universal parallel link structure which supports the radiation source, specimen, and imaging medium for relative oscillatory motion such that the imaging medium records a radiographic shadow image of a selected specimen cross-section only. The instrument may have an operating mode in which the imaging medium is held stationary and the specimen oscillates or an operating mode in which the specimen is held stationary and the imaging medium oscillates. When operating in the latter mode with a viewing screen as the imaging medium, the instrument is equipped with a direct viewing system which eliminates image movement at the viewing station.

摘要： A pair of wedgelike elements are mounted one above the other between a horizontal surface and a rail, with their inclined surfaces abutting each other. One of the wedgelike elements is moved laterally to raise or lower the rail, whereas both elements are moved laterally to cause the rail to move sideways.
