Abstract: POWER FACTOR CONTROL SYSTEM FOR INVERTER-DRIVEN     A-C INDUCTION MOTOR            Abstract:   The power factor in an inverter-driven induction motor is held relatively constant at a desired optimum value, despite variations in mechanical loading on the motor, by monitoring (27,28) the d-c bus current to determine the ratio of real and reactive currents, thereby to detect the actual power factor.  The actual and desired power factors are then effectively compared (31-42) and the resulting error signal is fed back to the inverter's d-c power supply to adjust the inverter output voltage to change the reactive current to the extent necessary to maintain the desired power factor.

Abstract: ABSTRACT    A magnetic control strip recording device for vehicle control systems.  A paving machine (12) lays a strip (10) containing magnetizable material.  A wheel (30) rotates in response to the movement of machine (12).  Magnets (34), (36) on the wheel and reed switches (38),  (40) adjacent the wheel are activated in response to the movement of the wheel.  An electromagnet (21) is energized when the reed switches (38), (40) are closed creating a magnetic pattern in the strip (10) of magnetized zones having alternating polarities  for adjacent zones.  An alternative magnetic pattern may also be produced by opening the optional dis-abling switch (44).  The switches (38, 40) are preferably capacitively coupled to the electromagnet (21) to prevent undue drain on the power supply should the wheel (30) be stopped with one of the switches (38, 40) closed.

Title: Facsimile mid-page restart

Abstract: FACSIMILE MID-PAGE RESTART                     Abstract The method and apparatus shown herein provide for restarting a facsimile operation after a mid-page interrupt without overlapping or splitting the image.  Furthermore, this is accomplished in a facsimile system that does not have a one-to-one synchronous relationship between synchronized mecha-nisms in the system.  In operation, a print carriage is synchronized to a false once-around signal related to the motion of a print drum.  There is a predete-rmined cyclic relationship between the false once-around and the real once-around for the drum.  If a mid-page interrupt occurs, the line position at the time of interrupt is remembered, and the particular relationship existing between the false once-around and the real once-around at the time of interrupt is remembered.  The carriage is backed up to a point prior to the mid-page interrupt and rests until restart.  Upon restart, the carriage is accelerated up to speed and resynchronized to the false once-around before it reaches the point of interrupt. The once-around to which the carriage is resynchro-nized has the same relationship to the real once-around as stored at the time of interrupt.  When the carriage reaches the interrupt point, that position is detected, and the facsimile system resumes printing on the next line without splitting or overlapping the image.

Abstract: Applicant:    Christopher Nilsen Title:        Tree Shear Blade Structure ABSTRACT            Bolts detachably mount a thin tree-shearing blade on a peripheral reinforcing blade carrier swingably mounted on a tractor.  The plunger of a hydraulic jack is connected directly to the blade, independently of the blade carrier, for swinging the blade to shear a tree.  The force applied by the jack to the blade is applied in the plane of the blade. To prevent excess stress from being applied to the bolts connecting the blade and the blade carrier as a tree is sheared, the blade carrier includes projecting backing plates fitted against opposite edges of the blade for transmitting force applied to the blade directly to the blade carrier.

Abstract: ABSTRACT          The invention relates to a method of controlling the energy management of a system for catching, accumulating and transferring heat comprising a heat collector and a heat accumulator of the thermally stratified type forming part of a heat recovery circuit adapted to pass a heat transport fluid, said heat accumulator forming furthermore part of a consumer circuit adapted to pass the heat transport fluid.Experiments have now shown that excellent efficiency is obtained by using this method in which the heat capacity flux, that is to say, the mass flux multiplied by the specific heat of the heat transport fluid through the consumer circuit and the mean value thereof during a selectable time interval, is determined or estimated at least by approximation and the heat capa-city flux through the heat recovery circuit is adjusted so that the difference between the mean value of the heat capacity flux through the heat recovery circuit during a time interval  of the same duration as said selectable time interval and said mean value of the heat capacity current through the consumer circuit is equal to a factor to be selected multiplied by the heat capacity of the heat accumulator, divided by said time interval, said factor lying between 0 and 3. Further the invention relates to a system for carrying out said method.
