    Abstract: A valve assembly has a spring-biased discharge valve seated for closing the discharge whereafter product is sucked back from a discharge nozzle during a continued movement of the valve in the direction of closing. Parts of the valve may be relatively adjusted for regulating the amount of suck-back flow of product from the nozzle.

    Abstract: The present invention is directed to a pulse oximeter sensor and an attached flexible carrier for measuring the oxygen saturation of a patient's blood. The carrier includes a compressible material, such as foam, for contacting the patient's skin and the sensor that applies a substantially uniform pressure to the skin.

    Abstract: Process, and apparatus, for the production of hydrogen and carbon monoxide in a reactor, preferably one containing a bed of a particulate solids catalyst, or catalyst and solids diluent, by contacting and reacting within the reaction zone a low molecular weight hydrocarbon feed, steam and oxygen, or a low molecular weight hydrocarbon feed and oxygen, at high temperature. An oxygen stream preheated to high temperature is fed via a nozzle inlet, or inlets, into the reactor, while the hydrocarbon and steam, or hydrocarbon, is fed via a different nozzle inlet, or inlets, into the reactor. Preferred oxygen nozzle designs are constituted of nickel-chromium-iron alloys, especially Inconel 600, and Inconel alloys of the 600 series generally. The oxygen nozzle is comprised of a tubular body with inlet, and outlets of special design, which renders the nozzle especially useful in the intensely hot oxygen environment.

    Abstract: A mixture of hydrocarbons, oxygen and steam is reacted over a fluidized bed, in a first reaction stage, at high temperature to produce, at hydrocarbon conversion levels ranging from about 85 percent to about 92 percent, a reaction product of hydrogen and carbon monoxide in admixture with unreacted hydrocarbons, carbon dioxide and steam. The level of hydrocarbon conversion is further increased by about 0.5 to 5 percent by contacting and endothermically reacting the reaction product mixture over a fixed bed of a high void fraction catalyst in a second reaction stage.
