Abstract: A radiation detector can include a photosensor to receive light via an input and to send an electrical pulse via an output in response to receiving the light. The radiation detector can also include a pulse analyzer to send an indicator to a pulse counter when the electrical pulse corresponds to a scintillation pulse and to not send the indicator to the pulse counter when the electrical pulse corresponds to a noise pulse. The pulse analyzer can be coupled to the output of the photosensor. A method can include receiving an electrical pulse at a pulse analyzer from an output of a photosensor and determining whether the electrical pulse corresponds to a scintillation pulse or a noise pulse, based on a pulse shape of the electrical pulse. The method can also include sending the electrical pulse to a pulse counter when the electrical pulse corresponds to a scintillation pulse.

The sacrificial metallic material can be a metal salt selected from the group consisting of water soluble zinc and cadmium salts. Water can also be present to serve two functions, as a curing agent for the polyurethane and as a foaming agent, producing carbon dioxide. A method is also providing for installing an EMI shielding gasket on an aircraft between a graphite skin panel and a metal frame member.

Abstract: An improvement has been found in the gas recovery section of a delayed coking process. In the improvement the compressor discharge is amine scrubbed to remove hydrogen sulfide. The compressor discharge is the entire vapor feed to the gas recovery section and contains about 90% of the hydrogen sulfide. This has been found to cause a significant drop in both the depropanizer and debutanizer pressure and allow a saving in the investment cost of the pressure vessel. Synergistically a reduced amount of hydrogen sulfide is present in the entire gas recovery section. The remaining 10% of the hydrogen sulfide is removed by amine scrubbing the fuel gas and propane/propylene fractions.

Abstract: Superconducting compositions of the general formula A.sub.n Q.sub.m Cu.sub.3 O.sub.y are prepared by wet mixing a combination organic acid salts, inorganic acid salts and oxides of A, Q and Cu, wherein at least one salt is an organic acid salt, drying the mixed salts, and then heating the resultant mixed salts to a temperature between 500.degree. and 950.degree. C. The temperature is maintained for a time sufficient to form a substantially orthorhombic superconducting composition. The method achieves good results with only one heating step. The presence of at least one organic salt causes carbonate and nitrate salts of A, Q and Cu to convert to oxides at temperatures between 300.degree. and 400.degree. C. With lower processing temperatures, semiconductor materials and superconducting materials can be processed together.

Abstract: Apparatus and method relating to the monitoring of a gas supply to determine the level of certain gas constituents in the supply. There is disclosed a method of monitoring air to determine the hydrocarbon content thereof exclusive of methane. Air is fed through a cold trap maintained at a temperature which produces condensation of the higher hydrocarbons normally found in ambient air at an urban location. Methane, however, passes through the trap. From the cold trap the air is directed to an analyzer, which continuously analyzes the air for hydrocarbon content. Air having all original hydrocarbons is fed the analyzer during intervals interspersed with intervals when the air fed the analyzer has had higher hydrocarbons removed. By comparing the hydrocarbon content of the two types of air, one is enabled to determine the content in such air of hydrocarbons exclusive of methane.
