Abstract: A chemical complex of Tc-99m with 1,2-dihydroxy-1,2-bis(dihydroxyphosphinyl)ethane is skeleton specific. The complex can be made by reducing pertechnetate ion and reacting the reduced technetium species with 1,2-dihydroxy-1,2-bis(dihydroxyphosphinyl)ethane. The complex is normally used in a biologically sterile, substantially isotonic aqueous medium as a skeleton imaging agent.

Abstract: A horizontal load independent field measuring system for containers comprising a triangular latticework structure (20), the nodal points (2,4) of which are arranged in two concentric circles, one (2) adjacent the container (1) being weighed and the other (4) adjacent the foundation, with the latticework (20) being formed of support bars (3) arranged in isosceles triangles. The sum of the bar (3) forces is independent of the horizontal forces acting on the container (1). Pairs of bridges (6,7) span between respective pairs of support bars (3,3-30) comprising a given triangle with a reference bar (5) being mounted between these bridges (6,7) and symmetrically disposed between the support bars (3). A displacement transducer (9) is associated with the reference bar (5) which is slidingly connected to the upper bridge (7) in order to measure the displacement of the upper bridge (7) against the unloaded reference bar (5) which corresponds to the average deformation of the associated support bars (3 ).
