Abstract: ABSTRACT OF THE DISCLOSURE          A pneumatic motor for rock drills and the like having a reciprocating piston with valves at its opposite ends for valving motive air to the piston head from both ends of the cylinder.  Large receivers are provided near the respective valves to accommodate availability of air on demand from the valves and to dampen pressure fluctuations.  One of the receivers is connected to an external source of fluid under pressure; while the two receivers are interconnected by tubing external to the pneumatic motor itself.  This permits the cylinder for the piston to comprise a simple tube provided with exhaust ports only.  Additionally, exhaust air and oil from an air motor, which rotates the rock drill, are directed into the area between the lower end of the reciprocating piston and a striking bar for the drill rod to lubricate the . reciprocating parts.

Abstract: ABSTRACT OF THE DISCLOSURE            A high intensity radiation source.  A liquid vortex wall is formed on the inside surface of an arc chamber to restrict the diameter of an arc generated between electrodes. The liquid vortex wall is obtained by utilizing a vortex generating means which includes an annular restriction through which the liquid must pass prior to entering the arc chamber. The annular restriction is of a dimension sufficient to allow adequate pressure and velocity throughout the arc chamber and to reduce or eliminate flow irregularities which could be transmitted to the liquid wall in the arc chamber. A nozzle may provide for establishment of the required axial vortex flow motion of both the liquid and gas while the liquid and gas are physically separated prior to their entrance to the arc chamber. A discharge chamber adjacent the arc chamber is tapered smoothly to prevent flow disruptions and fin means on the electrode is provided to reduce gas and liquid flow in the opposite direction to that normally occurring in the arc chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention discloses an aerodynamic braking device which comprises a sail having halves of equal area which are symmetrical about a central vertical axis and are balanced when held in the wind created during a skier's downhill run.  The sail has straight outer edges remote from the axis and hems along the edges forming sheaths to receive ski poles or the like.  The sheaths leave central areas in which the ski poles can be gripped, and the position of the grips is such that the areas above and below the line of the grips are equal so that the skier can effect counterbalancing of the wind forces above and below the line.  Indented pockets or balloon areas enhance the braking effect and provide more effective balance and speed control.  In use, the sail is held taut between the skier's outstretched hands and, with the counterbalancing of the forces and ease of manipulation of the sail, easy and effective control of the skier's descent can be accomplished.

Abstract: ABSTRACT OF THE DISCLOSURE     An electric circuit breaker capable of being opened and closed from a remote location.  The circuit breaker includes a stationary contact, a movable contact mounted on a carrier and a trip mechanism that trips the circuit breaker, moving the carrier to an open position upon the occurrence of an overcurrent.  The remote control assembly opens and closes the circuit breaker independently of the trip mechanism.  Upon receiving a signal from a timer switch, a motor operates, rotating a gear spring connected to the motor shaft.  An actuator has a tooth positioned between the wire layers of the gear spring. As the gear spring rotates, the tooth moves toward the motor, pivoting the actuator.  An operating rod, connected to both the actuator and the carrier. pulls the carrier to open the contacts as the actuator rotates.  When the contacts reach the open position. the actuator hits a switch to shut off the motor.
