Abstract: This invention relates to improved apparatus for mixing and dispensing a temperature controlled medicated douche from any source of water under pressure. Means are included for maintaining the solution thus discharged at a substantially uniform concentration throughout the entire flow of the solution, which means includes a cartridge of solid water-soluble medicament disposed in the flow path. The cartridge is shaped so as to present a substantially constant surface area in contact with the water flowing past it during all stages of the dissolution of the medicament. Means are also included so that the flow of water cannot occur unless a medicament cartridge is in place.

Abstract: A gas probe for penetrating the earth to sample gasses therefrom such as gases of putrefaction in a suspected burial area. A cylindrical sampling conduit extends from an outlet at the top to a sampling manifold having at least one outwardly opening at the bottom and is affixed to a pike at its lower end which is the earth piercing portion of the probe. The sampling manifold is surrounded by a sleeve having a sealing bushing and a cylindrical section the same size as the pike. The reciprocating sleeve at the bushing seals the sampling manifold and applies pressure to the pike to force insertion of the probe. When the probe is driven to its full depth, the reciprocating sleeve is withdrawn to expose the sampling manifold. Withdrawal of this sleeve defines a protected annulus for the manifold openings simultaneously creating a gradually expanding volume which draws gases from the surrounding soil for sampling.
