    Abstract: A system for isolating the mounting pads of a vibrating beam or tuning fork force transducers from longitudinal vibrations generated by transverse vibrations of the beam or tuning fork tines which extend between the mounting pads. The system includes an arrangement of longitudinally resilient support links and masses that flex responsive to change in the length of the beam or tines as the beam or tines vibrate transversely. The support links and masses thus isolate the mounting pads from the longitudinally vibrations of the beam or tuning fork tines while allowing transmission of forces applied between the mounting pads which vary the force dependent resonant frequency of the beam or tuning fork.

    Abstract: A force sensing device in which the oscillations of a vibrator are damped by applying a weight, force, which is to be measured directly against a vibrating element. The output of a transducer, which converts the vibrator's motions into an electric signal, is fed into a readout instrument, recorder, or computer for observation and evaluation.

    Abstract: A vibrating wire gage for use with a mine rockbolt. The wire is anchored within the hollow portion of a cylindrical gage body that has an adjustable lower member. Rotation of the adjustable member changes the tension in the wire and as a result its frequency of vibration. Forces acting on the bolt imbedded in the rock cause the gage body to deform as well as its wire since the upper end of the gage body is held to a rockbolt anchored firmly within the earth. By noting variations in the frequency of the wire from an initial setting, the change in the amount of force the rockbolt is under can be determined. A rotatable pick can be inserted through a hole in the lower adjustable member to mechanically pluck the wire. The readout of the vibrations from the plucked wire may be accomplished by a mechanics stethoscope held against the gage or by an electrically operated pickup head which engages the vibrating wire.

    Abstract: A flat vibrating measuring string or ribbon suitable for use with a vibrating string weighing apparatus. The cross-section of the string is selected with such a large ratio of the largest to the smallest cross-sectional axis that the resonant frequencies of the desired mth vibrating mode in the direction of the minimum bending rigidity are situated below the resonant frequencies of the first mode in the transverse direction. The string is also enlarged at its ends, preferably by means of interconnecting rounded portions, to minimize the peak stress where the string is clamped. To further minimize the tension at the ends of the string where they are clamped, the string is secured to a junction mass having a resistance and modulus of elasticity which is within an order to magnitude of that of the string.
