  • Patent number: 4711423
    Abstract: A shock and vibration mount for mounting a supported device to a supporting device comprises a first electric member between two rigid members such as to be strained only in compression under loads along a first orthogonal axis, and to be strained only in shear under loads along a second orthogonal axis; and a second elastic member between one of the mentioned two rigid members and a third rigid member disposed in series with the first elastic member such as to be strained only in shear under loads along the first orthogonal axis and to be strained only in compression under loads along the second orthogonal axis. Both elastic members are of elastomeric material having a low shear modulus as compared to the compression modulus so as to exhibit relatively low deflection under compression and relatively high deflection under shear.

  • Patent number: 4674725
    Abstract: An adaptive, controlled vibration mount comprises a base and a load support arranged for relative vibrational motion; a restoring spring mounted between the base and the load support; and an arrangement for applying selected variable Coulomb frictional damping to the relative vibrational motion such that the amount of variable frictional damping increases non-linearly as a function of increasing amplitude of the relative vibration motion.

  • Patent number: 4370888
    Abstract: Weighing apparatus for determining the tare and net weights of a container containing a liquid or a substance behaving like a liquid without requiring separate weighing of the empty container or its contents including apparatus for applying force to the container whereby force interactions between the liquid and the container are negligible for at least a predetermined measuring duration; and apparatus for sensing characteristics of the force applied to the container and of the motion of the container at the measuring duration for determining the tare weight of the container.

  • Patent number: 4346802
    Abstract: A device for preventing bridging of bulk material in the form of powder or granules during discharge from a storage container or during handling, comprising apparatus for applying a shearing force to the bulk material along an axis orthogonal to the flowpath direction axis and without appreciably compacting the bulk material.
