Abstract: A plurality of self-contained remote environmental data-monitor-control units communicate with a central collection point, including transmitting and receiving data, control signals, program parameters and alert signals. The central collection point includes a web page interface allowing end users to view real-time, current status as well as trended data in textual or graphical form. The central collection point processes and forwards alert signals received from a remote environmental data-monitor-control unit or a third-party monitoring system to an alert notification system which can accept alert signals via email, page, and direct point-to-point communication, processes the alert signal to verify validity and eliminate redundant signals, and notifies one or more pre-selected recipients of the condition which caused the alert via confirmable, person-to-person notification.

Abstract: A self-cleaning orifice assembly, for draining unacceptable accumulations of water from pipes and vessels associated with a turbine, is herein presented and claimed. The invention includes a two-position, movable stem having therein a plurality of ducts and the orifice. Their relative diameters and the flow itself are utilized to prevent blockage of the flow path.

Abstract: A method and system for allocating fluid flow draining from a fluid utilizing apparatus to first and second fluid sinks. The fluid flow is entirely routed to the first fluid sink for drain flow rates less than a predetermined flow rate and to the second fluid sink as well as the first fluid sink for drain flow rates at least as great as the predetermined flow rate. Fluid from the fluid utilizing device is received in a drain tank through an inlet port and is drained therefrom through an outlet port. The fluid flow rate through the outlet port is regulated by cooperatively modulating first and second valves arranged in parallel flow relation to allocate fluid flow to the first and second fluid sinks.

Abstract: A method and apparatus for controlling the gain of receivers in a computer-to-computer communications network using intelligence in the signal to control the receiver gain. Each of the computers in the communications network has associated therewith a transmitter and a receiver for transmitting and receiving data from one or more of the other computers in the system. Preferably, each such receiver has associated therewith an automatic gain control circuit which operates automatically to increase the gain when low level signals are received and to decrease the gain when high level signals are received. At least one of the receivers and preferably each receiver in the system has associated therewith a memory device for storing compiled data indicative of the anticipated signal level from every other transmitter in the system.

Abstract: A means for controlling compressed gas and lubricant pressure in a gas storage reservoir wherein the lubricant level in the gas storage reservoir will not vary due to changes in the gas pressure.

Abstract: A reheater arrangement for providing steam within a predetermined temperature and pressure range for turbine rotor gland seal devices. Steam taken from a steam source is divided by suitable control means into a first and a second portion. The first portion of steam is directed into the tubes of a shell and tube reheater element while the second portion is throttled to an appropriate pressure usable in the glands. The throttled second portion of the steam is then passed through the shell of the reheater element where heat from the first portion from the source of steam is exchanged with the second throttled portion of the steam to provide steam at the appropriate temperature and pressure for use in the gland seals.
