Abstract: A method and apparatus for converting three phase AC voltages on first, second and third input lines to DC voltage across positive and negative DC buses, the apparatus comprising a rectifier including first, second and third rectifier legs, each leg including a switch and a diode wherein the switch is linked between the positive DC bus and an cathode of the diode, an anode of the diode is linked to the negative DC rail and the first, second and third diode cathodes are linked to the first, second and third input lines, respectively, a DC bus voltage sensor linked to the positive DC bus and measuring the DC bus voltage to generate a measured DC bus voltage and a rectifier controller that receives the measured DC bus voltage, a reference voltage value and the three phase AC voltages wherein, when the measured DC bus voltage is at least equal to the reference voltage value, the controller turns on the switches in the first, second and third rectifier legs when the voltages on the first, second and third input li

Abstract: A beverage container is disclosed which includes a stackable cup and a stackable cover which have cooperating thread forms for selectively securing the cover to the cup in a substantially liquid-tight relationship. The cover has a beverage dispensing opening and a cap which is selectively operable to open and close the opening to prevent beverage in the container from being poured out of the opening and to selectively allow beverage to be poured or drunk from the opening.
