20140165595 | USE OF UNIDIRECTIONAL FLOW MODES OF MAGNETIC COOLING SYSTEMS - A dual-mode magnetic refrigeration apparatus includes beds of magnetocaloric material, a magnet to apply a time-varying magnetic field to the beds, a heat transfer fluid (HTF), a pump to circulate the HTF, a hot side heat exchanger (HHEX), a cold side heat exchanger (CHEX), valves to direct flow of the HTF, and a controller configured to control periodic switching of the valves to allow the apparatus to operate in a first mode and in a second mode. The first mode transfers heat from the CHEX to the HHEX. In the second mode of operation, the periodic switching of the valves is suspended to allow unidirectional flow of the HTF through the HHEX, the beds, and the CHEX such that heat is transferred from the HHEX to the CHEX. | 06-19-2014 |

20160025385 | MAGNETIC REFRIGERATION SYSTEM WITH SEPARATED INLET AND OUTLET FLOW - An active magnetic regenerative (AMR) refrigerator apparatus can include at least one AMR bed with a first end and a second end and a first heat exchanger (HEX) with a first end and a second end. The AMR refrigerator can also include a first pipe that fluidly connects the first end of the first HEX to the first end of the AMR bed and a second pipe that fluidly connects the second end of the first HEX to the first end of the AMR bed. The first pipe can divide into two or more sub-passages at the AMR bed. The second pipe can divide into two or more sub-passages at the AMR bed. The sub-passages of the first pipe and the second pipe can interleave at the AMR bed. | 01-28-2016 |
20160076797 | MAGNETIC REFRIGERATION SYSTEM WITH UNEQUAL BLOWS - A magnetic refrigeration apparatus includes one or more beds of magnetocaloric material, each having a hot side and a cold side. The apparatus also includes a magnet to apply a time-varying magnetic field to the one or more beds of magnetocaloric material, a heat transfer fluid, a means to circulate the heat transfer fluid, a hot side heat exchanger (HHEX), a cold side heat exchanger (CHEX), and a controller to control the flow of heat transfer fluid from the cold side of the one or more beds to the hot side of the one or more beds when the magnetic field on the one or more beds is high at an average flow rate of Φ | 03-17-2016 |

20130048484 | ROTATIVE DOUBLE CONTACT - A contact system for a pole of a low-voltage switchgear includes a rotary contact mounted movably in a rotor housing. The rotary contact includes at least a first rotary contact body having a first and second lever arm. Each of the lever arms include a lever arm end having a contact piece. A first and second fixed contact each cooperate with a respective one of the contact pieces. A first spring acts on the first lever arm and a second spring acts on the second lever arm. Each of the springs have a first support at a first end, a spring body and a second support at a second end. The first supports directly engage the first rotary body and the second supports are disposed at the rotary housing. Each of the spring bodies are disposed on a same side of the first rotary contact body. | 02-28-2013 |
