A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system. The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices. In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system.

  • Patent number: 9512963
    Abstract: A lubrication system vent valve includes a valve body having a flow passage with an inlet fluidly coupled with a supply and an outlet fluidly coupled with a dispenser, and a vent passage with an inlet port fluidly coupled with the flow passage and an outlet port. A closure element disposed within the vent passage has a threaded portion and is linearly displaceable between an open position where the vent ports are fluidly coupled to permit lubricant flow from the primary passage and out of the body through the vent outlet port, and a closed position at which fluid flow between the vent ports is substantially prevented. A motor has a shaft with a threaded portion engaged with the closure element such that shaft rotation in one direction displaces the closure element toward the closed position and shaft rotation in an opposing direction displaces the element toward the open position.

  • Patent number: 9464760
    Abstract: A gas filling nozzle with safety function includes a valve seat, a first thimble, a safety valve, an inner sleeve and a first spring; the first thimble is sleeved in the valve seat, the safety valve is disposed at the top of the first thimble, and the inner sleeve is combined at the top of the valve seat, thereby allowing the first spring to be disposed between the inner sleeve and the safety valve. So when the gas filling nozzle is subject to a high temperature environment, the high-pressure gaseous/liquid mixture inside a gas container is able to be discharged to the exterior through the safety valve, thereby preventing the gas container from exploding.

  • Patent number: 9387522
    Abstract: A digitally controlled current to pressure converter (CPC) and method of controlling same is provided. The method of controlling includes the step of periodically imparting symmetrically-opposed movement of a control valve of the CPC to loosen and flush accumulated silt therefrom. More particularly, the method may include the step of periodically introducing a small-amplitude symmetrically-opposed impulse to a controller that actuates a hydraulic control shaft of a three-way rotary valve. Also provided is a method of preventing malfunction due to faulty input or feedback signals received by the CPC, and a method of detecting the health status of multiple CPCs when used in a redundant configuration.

  • Patent number: 9243947
    Abstract: A drain pan level monitoring system of an air conditioning system comprises a level sensor that generates a level sensor output signal related to a sensed level of condensation buildup within a drain pan. A method of monitoring a liquid level buildup in a drain pan of an air handling unit comprises determining a level of liquid buildup in the drain pan and determining whether an action should be taken in response to the determined level of liquid buildup by comparing the determined level of liquid buildup to a predetermined value. A method of preventing liquid overflow of a drain pan of an air handling unit comprises monitoring a pressure related to a liquid level buildup within the drain pan and taking an action when the pressure meets a predetermined criteria.

  • Patent number: 9212671
    Abstract: In a pneumatic actuator for setting a control armature, a first working chamber and a second working chamber are pneumatically separated from each other by a moveable dividing wall to which the control armature is coupled in a force-transmitting manner. The dividing wall, in case of a pressure difference between the working chambers, is displaced in a first control direction. A positioner is adapted to output at least one pneumatic control signal to the first working chamber. The first and the second working chambers are pneumatically connected to each other via a pneumatic short-circuit duct with a balancing valve disposed in the short-circuit duct for at least one of closing or opening the short-circuit duct. The balancing valve is driveable by the positioner such that in case of a certain operating condition, the balancing valve pneumatically short-circuits the first and the second working chamber for achieving a pressure balance between the chambers.

  • Patent number: 9127750
    Abstract: A control device for an automatic transmission including a hydraulic actuator that is actuated on the basis of a hydraulic pressure supplied and a linear solenoid valve that controls the hydraulic pressure supplied to the hydraulic actuator on the basis of a driving current of a solenoid includes an ECU that executes current feedback control over a current value of the driving current that is flowed to the solenoid using at least a proportional term and an integral term on the basis of a deviation (?I) between a target current value (Itgt) and actual current value (Ir) of the solenoid such that the hydraulic pressure supplied to the hydraulic actuator becomes a target hydraulic pressure. The ECU increases a proportional gain (Kp) in the current feedback control as a fluid temperature (To) detected by a fluid temperature sensor increases.
