Abstract: An apparatus and method for the orthopedic treatment of a leg or other limb having a joint between its proximal and distal portions. Saddles are secured to the proximal and distal portions of the limb. A compression strut is secured between the saddles to the rearward side of the limb. A stay is secured between the proximal saddle and a saddle secured to and extending around the rearward side of the distal portion of the limb. The stay may be adjusted laterally relative to the saddles secured thereto whereby twisting force may be applied to the limb. Compression pads are disposed between the stay and the limb to either side of the joint whereby, together with the saddles, straightening forces may be selectively applied to the limb.

Abstract: A battery operated electric power plant for motor driven vehicles powered by rechargeable electric storage batteries and one or more dynamoelectric devices capable of operation both as a motor for driving the vehicle and as a generator for recharging the batteries. Electronic switching circuitry cyclically alternates operation of the dynamoelectric devices in a motor phase and generator phase during each cycle and varies the relative duration of the motor phase and generator phase during each cycle according to the power demand on the electric motor.
