Title: Improved cooling system for power transformer
Inventor: ANDERSON JEFFREY
IPC: H05K10/00
Filed: 2009-06-17
Abstract: A system for cooling a power transformer which generates heat, when driving a load, includes cooling devices located about the transformer which are powered to remove excessive heat from the transformer. The cooling devices may include fans to blow air onto the transformer and pumps for circulating a coolant about the transformer. The cooling devices of interest have a motor (e.g., a fan motor or a pump motor) which is energized in response to given temperature (heat) conditions. In systems embodying the invention, the currents flowing through the motors of cooling devices are sensed and monitored to determine whether the cooling devices are functioning correctly and to substitute functional cooling devices for those which are malfunctioning. The importance of sensing the motor currents and substituting operational cooling devices for defective ones is that a temperature rise due to a failure of a cooling device is not immediately detectable due to the large thermal constants associated with the transformer assembly. Sensing the currents in the motors enables the early detection of fault conditions in the cooling system. It also enables the monitoring of operating conditions and running time of the cooling devices to aid in the maintenance and operation of the cooling system.

Abstract: Described herein are a method and system for desalinating saltwater using concentration difference energy. A "five stream" dialytic stack is described that can be used to desalinate saltwater at a relatively high recovery ratio. The dialytic stack may include, for example, one or more drive cells having a paired concentrate and a diluent-c chamber in ionic communication with a product chamber that is adjacent to an anion and a cation discharge chamber each filled with diluent-p. The drive cell applies a drive voltage across the product chamber, and when the drive voltage exceeds a desalination voltage of the product chamber, the saltwater in the product chamber is desalinated. The diluent-p may be at a lower ionic concentration than the diluent-c, which may be at a lower concentration than the concentrate. The relatively high concentrations of the concentrate and the diluent-c facilitate a relatively high recovery ratio, while the relatively low concentration of the diluent-p facilitates a relatively low desalination voltage. The dialytic stack may accept brine discharged from a first desalination plant and may use this brine as a source of the concentrate, diluent-c, or diluent-p. Alternatively, the dialytic stack may accept the brine as saltwater to be desalinated, and may then output desalinated brine back to the first desalination plant for further desalination. Processing the brine in the dialytic stack may decrease its volume, decreasing costs associated with treating or otherwise disposing of the brine.

Abstract: A safety system indicating encroachment near dangerous equipment which is activated upon activation of the equipment is provided. The safety system has a transponder having unique identification information embedded in a microchip and an internal power supply. A corresponding reader is coupled to a power supply of the equipment, and has a transceiver and a scanning antenna which outputs a first radio-frequency signal to a pre-programmed radius. When the power supply of the equipment is flowing, the reader is put into an active state capable of receiving information from the transponder. When the transponder encroaches on the pre-programmed radius, the signal of the reader identifies the transponder's identification information, the transponder transmits data to the transceiver using the internal power supply, and the transceiver sends a second radio wave signal to a base unit causing a programmable logic controller to trigger a remote alarm.
