20100288586 | ELEVATOR MACHINE MOTOR AND DRIVE AND COOLING THEREOF - Heat in a drive system including a motor and a drive is removed using heat pipes in heat exchanging contact with the motor and the drive. The heat conducting element have at least one portion for receiving heat from the motor or the drive, and another portion to transfer heat to a heat exchange device that is spaced from the motor and drive. The heat conducting element may be a heat pipe or a heat spreader element. | 11-18-2010 |
20110132698 | INTUMESCENT THERMAL BARRIER FROM HUB TO TIRE - A door assembly has a door header mounted on a frame defining a doorway, a door movably supported on the frame, and a track including at least one supporting surface along at least one side of the track. The track is secured to the door header. The assembly has at least one roller that is adapted to roll along the track. The roller has a rim portion adjacent a hub portion, and a tire material surrounding the rim portion that contacts the track. The roller is at least partially covered with a thermal barrier between the tire material and at least one of the rim portion and the hub portion to prevent heat transfer to the tire material. | 06-09-2011 |

20120079859 | BATTERY FIRE PREVENTION VIA THERMAL MANAGEMENT - An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source. | 04-05-2012 |

20120291462 | Ejector Cycle Refrigerant Separator - A system has a compressor. A heat rejection heat exchanger is coupled to the compressor to receive refrigerant compressed by the compressor. An ejector has a primary inlet coupled with heat rejection heat exchanger to receive refrigerant, a secondary inlet, and an outlet. The system has a heat absorption heat exchanger. The system includes means for providing at least of a 1-10% quality refrigerant to the heat absorption heat exchanger and an 85-99% quality refrigerant to at least one of the compressor and, if present, a suction line heat exchanger. | 11-22-2012 |
