Circle diagram Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine's input voltage and current. The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero. Another common circle diagram form is as described in the two
What-A-Burger What-A-Burger What-A-Burger is the trading name used by a small group of restaurants which were established by entrepreneur brothers Jack Branch and Paul E. Branch Jr. and members of the Branch family beginning in 1950. With the first location at a busy traffic circle near Newport News, Virginia in the former Warwick County, they soon established additional locations in the cities of Richmond, Colonial Heights, and Petersburg, Virginia, each along busy through-traffic highway corridors. Another location was opened by a member of the Branch family in the 1950s in Greenville, South Carolina. The first Virginia store opened in 1950 by
