Abstract: SOOTBLOWING SYSTEM WITH IDENTIFICATION           OF MODEL PARAMETERS                  ABSTRACT OF THE DISCLOSURE     A method of identifying a parameter of a model for a rate of loss of boiler efficiency due to a soot-blowing operation, in a boiler having a plurality of heat traps, comprises measuring a time since a last sootblowing operation in the heat trap in question, measuring an overall boiler efficiency at the beginning of sootblowing for the heat trap in question, measuring a change in efficiency due to the sootblowing operation and calculating the parameter using an equation.          According to the equation, the ratio of efficiency change over overall boiler efficiency equals the time factor since the last sootblowing operation times the parameter minus a summation of factors for each of the other heat traps and their associated sootblowing operations.  The technique is extendable to individual sootblowers within a heat trap by using fouling rate index rather than overall boiler efficiency.

Abstract: FLYBACK SWITCHING REGULATOR                         ABSTRACT     In a power supply having transformer coupling for regulation of voltage by a pulsing of primary current, a control circuit integrates the output voltage to obtain a measure of flux and primary current.  A comparator monitors the integrated voltage to terminate a pulse of primary current prior to saturation of a core of the transformer.  This insures linear operation and efficient transfer of energy from the primary to the secondary windings of the transformer.  A sensor of secondary current initiates a new pulse of primary current when the secondary current has decayed to a fractional value of the peak secondary current.

Abstract: Abstract This divisional application encompasses the water ski pole disclosed herein and in the parent application.         The water ski pole, normally used as a mirrored pair, is meant to be used in conjunction with water skis of the type used to "cross country ski" on water.  On the bottom end of the pole is attached sufficient floatation to enhance the user's lateral stability, and to assist the user in forward, turning and rearward movements.     The shape of the floatation is designed to maximize its functionality, where previous designs, such as inverted cups or cans have been lacking.  The pole shaft can be telescopic to facilitate variations in length.
