A method of maintaining as well as restoring the condition of weathered asphalt shingles and strips which are applied to flat roofs, pitched roofs, or vertical walls. The process involves applying resaturant neat or as a water emulsion. Suitable resaturants include fatty acid methyl esters, petroleum distillates, and water emulsions thereof. The process restores the suppleness and softness of the weathered shingles or strip and adds about three years to the lifetime of the roof. The process may be repeated for additional lifetime extension.

The invention is a method for the treatment and decolorization of waste water incident to the manufacturing of cosmetic products that contains dyestuffs, fatty organic chemicals and other organic chemicals. The method requires a strong base which is added to the waste water at a suitably high temperature to cause flocculation of fatty substances. Then an strong colorless oxidizer is added to reduce the hydrophilic character of the remaining organic chemicals and cause partial decolorization. The resulting waste water is in a state that can then be decolorized with powdered activated carbon. Finally, the powdered activated carbon is separated from the waste water. The decolorized waste water is discharged in compliance with acceptable water quality standards for plant effluents.

A continuous process for the separation of small particles from larger particles in a biological preparation passes a liquid stream of the preparation through a first filter or screen, which retains larger particles, passing smaller particles in the liquid. The large particles have retained on their surfaces wetting water, in which are entrained some of the small particles. The large particles are directed to a liquid having a concentration of smaller particles lower than the concentration of smaller particles in the wetting water, and mixed therein. The smaller particles separate from the larger particles in the mixed suspension, which is then directed to a second filter or screen, for further separation. The smaller particle/liquid stream may be recycled to the biological preparation stage, the liquid suspension for the large particles, or to a separator means where the smaller particles are separated off from the liquid stream. As the system is susceptible of being practiced as a continuous closed system, given an adequate liquid supply, the filtering steps may be repeated any number of times. When separated at the filters or screens, at least a portion of the stream of small particles and liquid must be directed to the separation means, so that said small particles may be eventually separated.

This invention discloses a new apparatus for the rearing of insects and the production of insect related products, primarily insect viruses and parasites commonly used for the control of insect pests. The apparatus comprises an environmental control system, a sealed enclosure consisting of a hood and a base, and a system of vertically or horizontally supported food leaves. Laminar air flow may be used. The method of use in producing insects, insect viruses, insect pathogens, and other insect products is also disclosed. Use of this apparatus and method affords savings in labor and supplies.
