Abstract: Apparatus for measuring and/or supervising the output power of an induction motor comprising means for generating a first voltage signal proportional to the synchronous speed of the motor, means for generating a second voltage signal proportional to the actual speed of the motor in operation and means responsive to the first and second voltage signals for generating a third voltage signal proportional to the difference between the first and second voltage signals. The third voltage signal is applied to a meter for providing a continuous indication of the output power of the motor.
Abstract: A rack primarily adapted for connection to the inside curved wall of a van for carrying skis and the like. The rack includes a pair of brackets permanently connectable to the wall of the van and being sufficiently flexible to be curved to follow the contour thereof. A plurality of cradle members are connectable to the brackets, each cradle member being designed to lock to the adjacent vertically-spaced cradle members for added strength and support and to dampen vibrations. The cradle members are made from a flexible material to allow for slight adjustments in spacing therebetween as the brackets curve. The cradle members support the skis with an angular orientation to allow the bindings to overlap and also to hold the skis away from the wall of the van to keep the bindings and tips from striking the van wall.
