A system includes an electrical apparatus configured to monitor or control one or more aspects of an electrical power distribution network; and a control system including more than one electronic processor, where the electronic processors are configured to cause the control system to interact with the electrical apparatus, an interaction between the control system and the electrical apparatus including one or more of the control system providing information to the electrical apparatus and the control system receiving information from the electrical apparatus, and if some of the electronic processors are unable to cause the control system to interact with the electrical apparatus, at least one of the other electronic processors is able to cause the control system to interact with the apparatus.

Control system for an electrical apparatus

The present invention concerns improvements in electric defrost heaters used in frozen carbonated beverage machines. The frozen carbonated beverage machine includes freeze cylinders used to produce the frozen beverage. One or more tubes are secured in heat exchange relationship along the exterior of the freeze cylinder. Cartridge type heating elements are releasably insertable into the tubes to provide for defrosting of the beverage in the freeze cylinder.

Frozen confection machine and heating apparatus and method therefore

The present invention concerns improvements in the electronic control of frozen carbonated beverage machines and improvements in electric defrost heaters used therein. A control scheme is shown that provides for accurately determining the viscosity of a semi-frozen beverage as a function of the torque of a drive motor used in the harvesting and mixing thereof. The torque is first calculated based upon the current and voltage to the motor and the phase difference there between. The torque is adjusted to compensate for motor efficiency after which the net torque value is converted to a viscosity scale. The viscosity scale has a zero value relating to the net torque experienced by the motor when the beverage is known to be completely liquid. Viscosity is maintained within a narrow range based upon pre-defined three level low, medium and high viscosity sets, and wherein compressor short-cycling is eliminated. Recalibration control is shown for reestablishing a new viscosity zero value to allow for changes in the net torque at the beverage known liquid point that can result from machine wear, inaccurate initial calibration and the like. A safety defrost control is shown for reducing potential hazards associated with the use of electric defrost heaters. Improved electrical defrost heaters are shown that allow for easy removal and replacement thereof.
