Abstract: A highly efficient, highly accurate controllable digital viscosity testing system is provided. The system incorporates a variable speed motor, a digital encoder, a beam-deflection and/or magnetic torque resistance for unidirectional or bi-directional measurement of shear, and an API recommended practice 13B-11ISO 10414-1 bob and rotor sleeve measurement device for submerging in a test sample to measure shear forces exerted by the test sample.

Abstract: A torque measuring apparatus is described that comprises a chassis, a reversible electrical motor having a motor housing and a rotatable output shaft projecting from one end of said motor housing, motor mounting means mounting said motor housing for rotation relative to said chassis, means for connecting said motor output shaft to a rotatable component of a device to be tested, whereby energization of said motor will cause said output shaft to rotate and apply a torque to said rotatable component and the resistance to rotation offered by said rotatable component will result in a reactionary torque that causes said motor housing to rotate relative to said chassis, means responsive to rotation of said motor housing for generating a signal representative of said reactionary torque, and means for converting that signal into a measure of the torque applied by said motor output shaft to said rotatable component.

Abstract: A convertible container has side walls, a rear door, front end walls sloping downwardly in the direction of the rear door, a floor commencing at the rear door, and a gated hopper lying between the floor and the front end wall. A movably mounted sheet has first and second positions, the first position of the sheet lying between the side walls, covering the hopper. In the second position the sheet is supported between the side walls, over the floor, sloping downwardly in the direction of the front end wall, and between the hopper and the rear door. The convertible container can be part of a convertible vehicle including a tractor, tilt mechanism for tilting the container between a tilted and a substantially horizontal position, wheels supporting the container, and a towing mechanism pivotally connecting the tractor and the front of the container. The hopper may be employed to discharge dry bulk goods when the sheet is in the second position and the container is in the substantially horizontal position.
