  • Patent number: 8578709
    Abstract: In an over-loading prevention device including a hydraulic pump, a control valve, and a control lever, a discharge-quantity control unit performs constant-torque control which decreases a discharge quantity in proportion to an increase in a discharge pressure in the pump to control an input torque of the pump uniformly. An operation-state detection unit detects an actuation state of the control lever. A control unit outputs a control signal that sets the pump input torque to a minimum torque according to the constant-torque control, to the discharge-quantity control unit when the control lever is operated over a predetermined speed, and subsequently changes a level of the control signal to a maximum torque according to the constant-torque control in accordance with a predetermined control pattern to raise the pump input torque.

    Abstract: A heat pump is provided having a first heat exchanger and a second heat exchanger. A compressor is fluidly coupled to the first heat exchanger and the second heat exchanger. A reversing valve is fluidly coupled between the first heat exchanger and the second heat exchanger. The reversing valve is adapted to flow of a refrigerant from the compressor to the first heat exchanger during heating mode and to the second heat exchanger during a cooling mode. A thermal expansion valve is positioned between the first heat exchanger and the second heat exchanger. An electronic expansion valve is positioned between the first heat exchanger and the second heat exchanger. A controller is electrically coupled to operate the electronic expansion valve between a fully open, a fully closed and a modulated position depending on the operation of the compressor.

  • Patent number: 8578725
    Abstract: An air conditioning apparatus includes a refrigerant circuit, first and second shut-off mechanisms, a communication pipe and a refrigerant detection mechanism. The refrigerant circuit is configured to at least perform a cooling operation. The first shut-off mechanism is downstream of the receiver and upstream of the liquid refrigerant connection pipe when the cooling operation is performed. The second shut-off mechanism is downstream of the heat source-side heat exchanger and upstream of the receiver when the cooling operation is performed. The communication pipe interconnects the refrigerant circuit between the first and second shut-off mechanisms, and the refrigerant circuit on the suction side of the compressor. The refrigerant detection mechanism is upstream of the second shut-off mechanism when the cooling operation is performed.

  • Patent number: 8578726
    Abstract: A air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

  • Patent number: 8578729
    Abstract: Apparatus and methods for dispensing small amounts of a viscous material onto a workpiece. The narrow-profile dispensing apparatus includes a fluid chamber, a nozzle, and a valve seat disk representing individual components that are removable from a main body of the dispensing apparatus for cleaning and/or replacement. The nozzle is coupled with the fluid chamber by a heat transfer body that may be cooled by, for example, a cooling fluid routed through an air pathway defined in the heat transfer body. The main body of the dispensing apparatus may be cooled by air exhausted from an air cavity of a pneumatic actuator regulating the movement of a needle to control the flow of viscous material in the dispensing apparatus.

  • Patent number: 8578730
    Abstract: A safety system for an ice and liquid dispenser of a refrigerator is used to sense the presence of human skin in a dispensing well. The safety system includes a digital image capture device focused on a dispenser well for capturing images of objects, such as hands, in the dispenser well and a digital image analyzer operatively coupled to the digital image capture device. The digital image analyzer evaluates the digital images captured by the digital image capture device to determine if human skin color is detected in the image of the object in the dispensing well. If human skin color is detected, thus indicating a hand in the dispensing area, any dispensing operation will be prevented and an alert will be provided.
