Abstract: Device for instant, continuing meter display of relative engine torque and tachometer output together with power indication. The engine torque and power read-out derives from electro-mechanically coupling the engine to the dynamometer to sense the motion caused by the torque reaction of a motor or other torquing force. A motion sensor outputs a signal which can be made to read-out directly in torque on either a relative or absolute scale. Power indication is obtained by multiplying the tachometer and torque signals so that the resulting output is directly read-out in horsepower on either a relative or absolute scale.

Abstract: Alarm system in which the latch plate of the door jamb is movable to contact a striker plate spaced and insulated therefrom to close an alarm circuit. The system is so designed that if an attempt is made to force the lock, the latch plate which is resiliently mounted will move and thus make contact with the striker plate. A contact relay and thermal relay are incorporated in the alarm system in such a way that the alarm can be timed to signal for a predetermined length of time after which it will automatically shut off. As soon as the alarm signal has stopped the system is ready to signal again.
