摘要:
Fiberizer (10) efficiency is improved by providing an inline control valve (15) at the fiberizer feed inlet which automatically provides the fiberizer (10) with make-up air proportional to the preessure differential between the fiberizer outlet (12) and the inlet. The make-up air tends to distribute the feed material (5) more evenly within the feed inlet (9) and provides a constant fiber/air ration within the fiberizer (10).

A system for blending low and high octane gasoline includes independent flow paths for each fuel between a supply source and a composite blend manifold and nozzle assembly, with the rate of flow of fuel in each flow path being under individual closed loop control, under an algorithm for comparing the ratio of the actual accumulated volumes of the low octane to the high octane fuel, relative to a statistically determined ratio of the ideal volume of said low to high octane fuel for the total actual accumulated volume of the sum of the volumes of the fuels at a given time, for providing a perfect blend relative to a preselected blend ratio.

Die Gasregeleinrichtung enthält in den Zuleitungen zum Zerstäuber, Oxidansanschluß und Brenngasanschluß des Brenners je einen Druckregler (35,40,54) und je einen, dem Druckregler nachgeschalteten Strömungsmesser (43,45,59). Die Strömungsmesser enthalten ein Turbinenrad (49), das von dem durchströmenden Gas beaufschlagt ist und durch dessen Drehung von der Drehgeschwindigkeit und damit von der Gasströmung abhängige Ausgangssignale erzeugt werden. Diese Ausgangssignale werden in die Steuereinheit (28) eingegeben, und die Stellmotore (37',46,56) der Druckregler (37,40,54) werden reproduzierbar auf bestimmte Gasströmungen eingestellt.

A micro-fluidic valve system is provided which includes a micro-fluidic valve actuator apparatus, a fluid distribution manifold and a micro-fluidic POD apparatus. The POD apparatus includes a POD housing that defines an interior central passage extending from a distal mounting end of the housing to a proximal portion thereof. The POD apparatus further includes a stator device disposed in the interior central passage, and includes a distal stator face that cooperates with an opening in the distal mounting end to define a gasket receptacle. A relatively thin, elastomeric gasket member is disposed in the gasket receptacle of the housing in abutting contact between the stator and a communication face of the manifold. A fluid-tight seal is then formed between each respective stator communication port of the stator device and a corresponding manifold communication port of the manifold.

A system is configured to generate a pressurized flow of gas comprised of a first gas having a partial pressure that varies in a predetermined manner. This may be used, for example, to simulate a previous and/or theoretical respiratory gas flow that was produced (or could have been produced) by a subject. The system is configured to deliver the pressurized flow of gas to a testing system configured to measure the partial pressure the first gas in flows of gas. This may provide an opportunity to determine the response of individual testing systems to various clinical circumstances.

摘要:
A pressure proving gas valve (10) insures safe and efficient operation of a fuel-burning appliance by monitoring combustion airflow and appropriately controlling the valve based (22) upon this airflow. An airflow sensor (26) is incorporated into a pressure proving valve housing (20) itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber (12) unless appropriate combustion air is sensed. Further, by monitoring the actual airflow, additional control capability is provided. That is, a variable speed blower (60) associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.
