Abstract: The apparatus is a cooling structure for reaction engine throats. The constriction in the throat is cooled by a group of heat pipes which radiate outward from the constriction to a larger diameter perimeter surface where the heat is dissipated. The entire structure can be constructed by embedding pretested heat pipes around a base structure with plasma sprayed metal.

Abstract: A method and optrode for detecting gem polyhalogenated hydrocarbons in a sample fluid based on a single phase Fujiwara reaction as provided. The method comprises contacting a reaction mixture with a sample fluid which contains the gem-polyhalogenated hydrocarbons. The reaction mixture comprises an aqueous solution of pyridine or derivative thereof and a hindered nitrogen base. Upon contact a fluorescent and/or chromgenic reaction product forms whose fluorescence and/or absorbance is related to the concentration of gem-polyhalogenated hydrocarbons in the sample fluid.

Abstract: A method for the control of bluetongue disease amongst sheep by the application of O, O-dimethyl O-p-(dimethylsulfamoyl) phenyl phosphorothioate directly to the back of the animal. Such application of a chemotherapeutic dosage prevents contamination of the animal by the bluetongue virus carrying gnat (Culicoides).

Abstract: A System and Cold Cabinet Server therefor to condition pre-packaged foods and to maintain them at serving temperature during storage and for customer access. A structural relationship of means is provided in cooperatively related bin type cabinets to combine the inherent principles of convection, absorption and recirculation to maximum advantage and to the end that heat induction from the surrounding atmosphere is minimized despite the completely open and accessible bin configuration. The Cold Cabinet is a self-sufficient entity provided with a replaceable refrigeration unit supplied with power such as an electrical plug-in, and is completely mobile; and adapted to be quickly assembled in service lines that are readily modified or broken down for storage.

Abstract: A system and Hot Cabinet server therefor to condition pre-packaged foods and to maintain them at serving temperature during storage and for customer access. A structural relationship of means is provided in cooperatively related bin type cabinets to combine the inherent principles of convection, conduction and recirculation to maximum advantage and to the end that heat loss is minimized despite the completely open and accessible bin configuration. The cabinets are each a self-sufficient entity when supplied with power such as an electrical plug in, and each is completely mobile while in operation; and being of the same height and width configuration, they are adapted to be quickly assembled in service lines that are readily modified or broken down for storage.
