Abstract: Household-strength bleach contains just two essential components, hypochlorite and hydroxide, and the hypochlorite is well-known to damage soft fabrics. In this invention is discovered a third component, the concentration ratio which is the concentration of hypochlorite over the concentration of hydroxide in the bleach solution. Although considered impossible, hypochlorite bleach can be made fabric gentle by elegantly balancing the concentrations of hypochlorite and hydroxide, requiring no ingredients commonly added to mitigate the damaging effect of hypochlorite. It's all in the ratio (or the reciprocal). By adding hydroxide to a solution of given hypochlorite salt concentration, the bleach fabric protection progressively improves for ratio values below 12.5:1, reaching maximum protection at a ratio value about 2:1. By comparison, the ratio value is >30:1 for fabric-damaging common regular bleach.

Abstract: A rolling liquid herbicide applicator with an adjustable shield is attached to a hollow pole having an adjustable width protective shield mounted to one end weighted, textured wheels for rolling over most terrains are attached to the adjustable width protective shield. On the opposite end of the hollow pole handle is a trigger. When the trigger is activated, an internal trigger stick is moved down through the hollow pole, thereby causing a “C” shaped piece to move upward. This upward movement pushes on a hard flat disk. The movement of the hard flat disk causes pliable cap center to move. The gravity flow of liquid herbicide from a liquid herbicide container causes the liquid herbicide to move through a tube and nozzle assembly. The adjustable width protective shield over the nozzle prevents overspray and accidental contact of the liquid herbicide on healthy desired vegetation.

Through spraying, deposition may be efficient and effective and allow for implementations which are impractical and/or not possible with bulk metal materials.

Abstract: An extended-duration foam may be used to entrap and suppress waste deposited into a latrine storage tank. The foam floats on a liquid or solid surface to form a protective barrier between the waste material stored in the latrine storage tank and the indoor atmosphere of the latrine.

The foam “self repairs” after the material passes therethrough, maintaining an effective visual and olfactory barrier between the waste material and the latrine atmosphere.
