Abstract: A clean, cool stream of low BTU gas is heated and saturated with water vapor by means of a hot liquid stream containing water. Contamination of the gas stream by droplets, particulate matter and salt content of the liquid stream is obviated by maintaining separation between the gas and liquid phases by means of a microporous barrier. The barrier is made of a material selected from the group consisting of hydrophobic polymer material and hydrophilic polymer material having a gel structure.

Abstract: Disclosed is a process for preparing oligomeric polyetheramide-acid by reacting an aromatic dianhydride component including an aromatic bis(ether anhydride) with an organic diamine in an inert organic liquid selected from methylene chloride, chloroform, 1,2-dichloroethane, and mixtures thereof with acetone. The oligomeric polyetheramide-acid is substantially insoluble in the inert organic liquid, in which the oligomer typically appears as a precipitate which may be recovered in powder or finely divided particulate form without need for grinding.

Abstract: A furnace for practising temperature gradient zone melting on one or more semiconductor bodies comprises a closable work chamber for receiving semiconductor bodies for processing, a radiant heat source which forms a first closure member and a heat sink which forms a second closure member, the closure members defining the work chamber and being mutually separable by, for example, a hydraulic actuator to allow access to the interior of the work chamber. A reflector is disposed between the heat source and heat sink in surrounding relationship to the semiconductor bodies being processed to ensure the maintenance of a uniform temperature gradient within the work chamber. The reflector and the heat sink are liquid cooled for the effective removal of heat therefrom. The heat sink is further provided with a plurality of radiation attenuating cavities to enhance the performance of the heat sink.

When utilized with a potentiometric titrator, the method of the invention also can be used to determine imide functionality of polyimide.

Abstract: Clinically useful diagnostic devices are prepared from commercially available metal sheet stock by a sequence of steps. The metal is one of a type on the surface of which a tenacious oxide layer can be produced. Steps in the preparation include roughening surface area of the bulk metal with pits on a fine scale to render that surface area of the metal non-specularly reflecting, chemically etching the surface area to produce some first preselected measure of reflectivity, anodizing the surface area to produce a dull, non-specularly reflecting oxide surface having a second preselected degree of reflectivity and applying a layer of protein over this dull surface area. The preferred metal is titanium and the reflectivity of the modified surface area is selected dependent on the immunological reaction being detected.
