Abstract: Disclosed is a frequency converter system for altering the frequency of a-c power supplied from a distribution network to a load, the system including a pair of mechanically coupled rotating alternating current machines, the alteration of the rate and direction of rotation of the prime mover altering the frequency of the power. A variable impedance network comprising saturable core reactors and connected in the rotor circuit of the prime mover is utilized to effect the change of rate and direction of prime mover rotation.

Abstract: Disclosed are a method and system for monitoring and controlling the normally inaccessible dynamic operating conditions, such as well fluid head and motor terminal voltage, of a well pumping operation, in response to monitored conditions at the top of the well. At the heart of the system is a computer having, stored therein, coded data representative of the fixed well, motor, and pump characteristics and programs defining the mathematical relationship between the stored fixed data, dynamic operating conditions of interest, and the monitored conditions. Feedback control for regulating the well fluid head and motor terminal voltage include the computer and uniquely designed frequency converter and line drop compensator apparatus.

Abstract: Disclosed is a voltage regulation-unbalanced voltage compensation control connected intermediate the supply and load of the polyphase system, the control including separately adjustable variable impedance elements provided by saturable core reactors for independently varying the voltage drops between the supply and load terminals for each phase. The independent adjustment of the variable impedance elements is effected by a feedback control network varying the magnitude of current supplied to the DC control winding of each saturable core reactor in response to the existing load voltages across the load terminals.

Abstract: A method of setting or coating hair, fur, synthetic or human in a predetermined condition, either straightened or curled, or waterproofed, which comprises coating the hair with a heat-settable coating composition containing a hardening and adhesive agent in oil and aqueous media, either with or without the addition of separate water-proofing agents, softening agents, and the like and then applying heat to the coated hair to set the coated hair in the selected condition.

Abstract: The method and means of dry lubricating the skin of human and animal by applying a dry lubricating powders of perfluorocarbon and or fluoropolymer resins, said lubricating powders being inert to human and animal skin tissue, nonagglomerative, and sized to fit smoothly within the crease lines of human and animal skin tissue.

Abstract: A hair and scalp conditioning and cleansing composition which contains perfluorocarbon resins as lubricating and/or scouring agents is disclosed.

Abstract: Negative sequence compensation apparatus for reducing, and thereafter minimizing the increase of, negative sequence currents flowing in a three phase motor includes variable impedance elements, and means for adjusting the impedance thereof, disposed in the motor supply lines. Alternate embodiments disclose saturable reactors as the variable impedance elements electrically connected with the supply terminals by way of alternate transformer connections.

Abstract: Motor protector apparatus for independently sensing the respective positive, negative, and zero sequence currents flowing in the supply lines to a three phase motor for interrupting power to the motor whenever such positive, negative, or zero sequence components reach levels indicative of abnormal operating conditions. The protector network includes bridge means for segregating the negative and positive sequence components, indicators for visually displaying the source of the abnormality, and means for restoring power to the motor after a defined time period.

Abstract: A method of setting hair in a predetermined condition, either straightened or curled, which comprises coating the hair with a heat-settable composition containing a hardening and adhesive agent in aqueous media, either with or without the addition of separate water-proofing agents, flame-retardant agents, softening agents, and the like, and then applying heat to the coated hair to set the coated hair in the selected condition.
