| 20100262707 | REMOTE OPERATION OF PROCESS CONTROL EQUIPMENT OVER CUSTOMER SUPPLIED NETWORK - A DCS protocol message addressed to a remote DCS station is generated at a local distributed control system (DCS). The DCS protocol message is received at a local tunneling device. The local tunneling device packages the DCS protocol message into a SCADA protocol message. The SCADA protocol message is transmitted from the local tunneling device to a remote tunneling device. The remote tunneling device receives the SCADA protocol message. The SCADA protocol message is unpackaged into a DCS protocol message at the remote tunneling device, and the DCS protocol message is placed on to a remote DCS such that it flows to the remote station. The DCS protocol message is received at the remote station. | 10-14-2010 |

| 20110005251 | Compressor discharge valve providing freeze and charge migration protection - A refrigerant system includes a compressor with a discharge valve that temporarily restricts the compressor's outflow at startup so that the discharge pressure can quickly rise to force lubricant back to the compressor. The discharge valve also helps prevent an axial face of a rotor of a screw compressor from rubbing against a bearing housing axial face of the compressor's housing. When the system turns off under certain low ambient air temperature conditions, the valve closes to help prevent the system's evaporator from freezing up. The discharge valve includes a novel arrangement of a piston, a valve stem extending from the piston, and a valve plug pivotally attached to the valve stem. The pivotal connection ensures a positive seal between the valve plug and a valve seat. A somewhat restricted fluid passageway between the valve's discharge chamber and piston chamber helps prevent the valve from chattering as the valve opens. | 01-13-2011 |
