摘要： A system by which a supplier of wet steam may allocate and measure the mass flow rate and quality of steam delivered to a demand user and one or more secondary users with the wet steam delivered to each user being measured for purposes of billing. Pressure regulator means between the demand customer and the secondary customers responsive to pressure changes caused by the amount of steam going to the demand customer. The demand customer thus being able to take from 0 to 100% of the steam generator output with the remaining steam being allocated to the secondary customers.

摘要： A drop sensor detects a drop of a device. When the drop of the device is detected, a sub CPU allows a counter to count a drop time. When the device drops for a predetermined time or more, the sub CPU controls a regulator so that the regulator forcibly disconnects an electric power to be supplied to a hard disc, and writes a drop occurrence flag into a nonvolatile memory. When the power supply is again turned on, a main CPU allows a display section to display information indicating that the power supply is disconnected due to the drop of the device.

摘要： A self contained unit for controlling the volume of airflow through an air duct ventilation system has an inflatable bag which is operated by the pressure of airflow in the duct to variably position a normally open damper and control airflow through the duct. Inflation of the bag pivots an overlying plate and connecting linkage to reliably position the damper. A pneumatic thermostat controls exhaust flow from the bag to adjust pressure therein. An aspirating nozzle in the thermostat is fed with relatively high velocity airflow from the duct, and by aspiration induces a flow of ambient air through the thermostat and across a bimetallic, thermally responsive control element thereof which moves in response to changes in temperature to vary pressure in the bag.

摘要： An air distribution system for supplying conditioned air to at least one zone to be conditioned and comprising a supply duct connected with a diffuser discharging to the conditioned zone. A modulating valve is provided with a bellows actuator and a control for the actuator is of the fluidic type with power for the actuator and control supplied from a total pressure pick-up in the duct. A duct static or differential pressure signal is fed to the fluidic control together with a pressure set-point and a zone temperature signal. Zone temperature may be measured at the diffuser with a total duct pressure powered aspirator drawing air over a thermostat or a zone located thermostat may be provided. A warm up override is optional. The fluidics comprise a multistage proportional amplifier and a diaphragm amplifier controlling an orifice in a total duct pressure conduit. A venturi in the conduit has its throat section connected with the bellows actuator selectively to pressurize and draw air therefrom whereby to adjust valve position.
