  • Patent number: 10908039
    Abstract: Disclosed is a load cell having a frame that includes a first and a second mounting surface. Each mounting surface is arranged on a common horizontal plane symmetrically about a central vertical axis. First and second lateral surfaces are arranged perpendicular to the first and second mounting surfaces. One or more mounting fixtures are located on the load cell at the first and second mounting surfaces and configured to attach to a support structure or a loading fixture. One or more force sensors are arranged symmetrically about the central vertical axis. One or more cavities extend the width of the frame and are arranged between a mounting fixture and the force sensors to buffer horizontal shear forces.

  • Publication number: 20090270655
    Abstract: A process for converting alkyl halides to alkyl alcohol alkoxylates is described. This is a direct alkoxylation because the alkyl alcohol alkoxylates are made without going through an alkyl alcohol intermediate. The process comprises direct alkoxylation coupling of alkyl halides with a nucleophilic material in the presence of a homogeneous catalyst system to produce alkyl alcohol alkoxylates, wherein the homogeneous catalyst system comprises at least one metal or metal compound which has the ability to form metal-halogen bonds. A process for converting alkanes (paraffins) to alkyl alcohol alkoxylates is also described.

  • Publication number: 20090054274
    Abstract: A process by which alkyl halides may be reacted (coupled) with nucleophilic materials in the presence of a homogeneous catalyst system. The process comprises reacting (coupling) alkyl halides with a nucleophilic material in the presence of a homogeneous catalyst system to produce derivatives of alkyl halides, wherein the homogeneous catalyst system comprises at least one metal or metal compound which has the ability to form metal-halogen bonds.

  • Patent number: 6552278
    Abstract: The multiple load sensing multi-load cell scale is described that provides improved utility to scales with multiple decks that share load cells near supports so that more than one load may be determined at the same time on a single scale. In more detail, the scale uses the sectional sensitivities to load movement on the scale decks, load position and individual normalized load cell outputs to provide separate load magnitude measurements on these individual decks. According to the present invention, more than two load cells associated to form a single scale provide outputs that are converted to individual digital representations of the relative force magnitude on each. These magnitudes are related to the effective location of each load cell to provide the load centroid location on the scale when the sum of the products of the effective location and magnitude of each is divided by the sum of the magnitudes.
