Abstract: A method and apparatus for collecting gas samples associated with underground minerals. A plurality of small gas sample containers are planted in an inverted position in shallow holes in the surface of the earth in a predetermined pattern, and upwardly migrating gases associated with the underground minerals being sought are collected in the containers for a predetermined time period, to obtain a time-integrated representation of the amount of one or more gases of interest migrating to the surface over that time period. Two types of containers are alternately employed: A total gas sample container in which all upwardly migrating gases are admitted into a sealed compartment at a preselected flow rate; and a specific gas sampler container in which strips of detector material which are sensitive to predetermined specific gaseous substances are mounted within the inverted container and exposed to the upwardly migrating gases over the predetermined time interval.

Abstract: Flaws in the surface of a physical object, such as cracks, breaks, and other physical discontinuities in metal surfaces are detected by inspection under ultraviolet irradiation after the surface has been coated with a novel flaw detection medium comprising an organic liquid solution of particular organic phosphor materials with an organic binder. The soluble organic phosphor materials found useful in this manner exhibit luminescence when excited by ultraviolet irradiation and are selected from the general class of heterocyclic aromatic nitrogen compounds. In the present inspection method, a coating of the flaw detection medium is applied to the surface being inspected and the dried coating then removed except at the flaw sites prior to inspection. The present liquid flaw detection medium can also be prepackaged for convenient dispensing from a pressurized container through use of conventional propellants such as fluorinated hydrocarbons or their equivalent.

Abstract: A photoflash unit is designed to have a plurality of lamps fired individually and in sequence and includes a plurality of switching devices capable of being easily activated by radiant energy generated during flashing of the lamps. Initially, the switches have a high resistance ("off" condition) and after being activated by radiation, they undergo a chemical change to a conductive state ("on" condition). The switches are prepared from compositions which impart improved shelf life to the switches under conditions of high relative humidity.
