Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for deriving power output from wave energy is disclosed.  A rotatable member is provided which is capable of rotating in only one direction.  A float is provided which rises and falls in response to wave action, and thereby moves relative to the rotatable member.  The float is coupled to the rotatable member so that the movement of the float rotates the rotatable member in its available direction to provide power output.  In its preferred form, the present invention provides an elongate floating barge flanked by a pair of elongate floats.  Trans-verse movement of the floats relative to the barge is limited.  A movement of the floats relative to the barge is limited.  A rotatable output shaft is mounted on the barge parallel to the elongate floats.

Abstract: SYSTEM FOR EVALUATING THE CAPABILITY OF A WORK PERFORMING ROBOT TO REPRODUCE A PROGRAMMED SERIES OF MOTIONS          Abstract:         A system for evaluating whether a work-perform-ing robot can perform a series of programmed motions is disclosed which includes means for continuously comparing the velocity of the various links of a robot simulator, which is manually moved through the sequence of motions to be programmed, against predetermined velocity limits associated with the corresponding links of the work-performing robot which will reproduce the programmed steps, and providing humanly perceptible alarm indica-tions uniquely identifiable with the various robot links when the motions manually programmed on the robot simula-tor exceed the velocity limits of the work-performing robot.  Additionally, the individual velocities of the various robot simulator links are summed, and the sum continuously compared against the power limit of the hydraulic pump driving the link actuators of the work-performing robot.  Should the aggregate velocity of the robot simulator links exceed the power capability of the hydraulic pump, that is, the pump capacity, an alarm indication is provided.  In spray coating robot applica-tions, the alarm indications occasioned by excessive link velocities, as well as excessive demands on the hydraulic pump, are recorded along with information indicating whether or not during a particular alarm condition the spray gun was ON or OFF.  This record enables the manually programmed motion sequence to be evaluated to determine whether or not the alarm conditions which occurred during programming can be safely ignored and the program used to operate the work-performing robot.

Abstract: Abstract A method is disclosed for controlling the operating parameters of an electrostatic precipitator of the type having electrodes energized by pulses superimposed upon a DC-voltage. According to the method, the pulse height (i.e., amplitude) is continuously increased at a predetermined rate and spark-overs are thereby detected as reductions in the precipitator-voltage below a selectable set value and are sorted in different types according to the time of their occurrence and duration. Thereafter, the operating parameters of the precipitator are altered in dependence upon the characteristics of the actual spark-over.

Abstract: Control System and Method for DC Pulse Modulated Arc Welding Abstract A method of pulsed direct current (DC), arc welding with a feedback control system is disclosed wherein the duty cycle of current pulses supplied by a power supply is controlled in response to resistance sensed at an arc gap to maintain a constant time-averaged power flow to work pieces which are welded.  The feedlock control system includes a voltage sensor, a high-low regulator, and a duty cycle signal generator.  This pulsed DC arc welding is especially useful with a type of pulsed DC arc welding wherein the ratio of peak current to maintenance current is maintained at a selected high value and the current is cycled in a time duration whereby oxides on the surface of the work pieces are dissipated when making the weld. Also, a control system is disclosed for automatically adjusting pulse width of current pulses supplied at an arc gap by a pulsed DC arc welding system power supply, to control power flow to work pieces at the arc gap.
