Abstract: A Prony brake used as a rotational load absorption unit, or dynamometer, to measure power output of a prime mover includes a cylindrical tube, or drum, disposed within a sealed tank containing coolant water. Disposed within the cylindrical tube in a sealed manner is a fixed stator shaft. The stator shaft is attached to the center of a generally circular, planar stator plate having its outer periphery disposed in closely spaced relation to the tube's inner surface, with the stator shaft further coupled to a hydraulic control system. Disposed within the stator plate's outer periphery are plural radially spaced pistons responsive to the hydraulic control system for applying a radially outward friction braking force to the inner surface of the rotating cylindrical tube. The stator shaft is provided with first and second ports and passageways for respectively transporting hydraulic control fluid and lubrication fluid. Also included is a supplemental cooling water supply wherein cooling water is circulated with the Prony brake by the rotating cylindrical tube.

Abstract: The invention relates to a torque metering device for a bicycle-type ergometer, in which ergometer the braking force is steplessly adjustable and in which the rotating movement is compensated by means of a flywheel. The rotating movement of the flywheel can be braked by means of a belt (5) which is pressed against the outer periphery of the flywheel and moves limitedly with the flywheel. The movement of the belt (5) with the flywheel is restricted by means of a spring member (6) connected to one end of the belt and the frame structure of the ergometer. In order to provide a reliable and easily readable metering device, the device is so constructed that it comprises a pin member (7) fastened on the belt (5) and means (8) for rotating an indicator (10) journalled for rotation. The rotating means (8) of the indicator are journalled on the frame structure (1) at the central portion thereof. One end of the rotating means (8) of the indicator is connected to the pin member (7), the other end being correspondingly secured on a shaft (12) of the indicator (10) in such a manner that a linear movement of the pin member (7) moves one end of the rotating means around the journalling point (11) of said means, thus effecting a corresponding rotating movement of the other end of the rotating means (8), which movement turns the indicator (10).

Abstract: A device for controlling the braking power in a brake equipment of a bicycle exerciser is capable of keeping the brake power of this equipment constant or giving it a programmed variation. The device comprises a non-electronic comparing means, which compares the existing power of the equipment (represented by a first r.p.m.), with the desired power of the equipment (represented by a second r.p.m.). If there is a difference between these two r.p.m., the comparing means delivers an output signal in the form of a third r.p.m., which signal is utilized to control a brake setting means for the brake equipment, such that the first and the second r.p.m. are brought into accordance.
