    Abstract: Apparatus and methods for analyzing substance in a rotatable body whereby vibrations caused by the body rotating with a known amount of weight applied thereto are compared with the rotations of the body rotating without the known amount of weight. Vibration signals storage means enable the signals to be applied to a meter as desired and adjustment means for the meter are provided so that the meter may be calibrated for direct readout of the amount of unbalance.

    Abstract: A control assembly for a reversible motor operating a drive wheel in a wheel spinner used for vehicle wheel balancing or the like including a power switch for actuating the motor when the drive wheel is moved into engagement position with the vehicle wheel and a reversing switch for selectively reversing the direction of rotation of the drive wheel. The control assembly includes locking structure for the two switches so that a polarity to the motor cannot be changed with the power switch in a closed condition and the power switch cannot be closed with the reversing switch in an intermediate condition. A brake is also provided for the drive wheel when returned to its non-engaging position to stop the motor before the motor polarity can be reversed.
