A shingle insert and method for eliminating and preventing growths on a shingled roof in which copper strips forming the inserts are installed with an upper edge disposed beneath a course of shingles with the remaining portions of the insert exposed. The insert strips have a confined space defined beneath a stiffening lengthwise extending arched hump formed in the exposed copper strip portions which has an array of elongated indentations formed therein with slits therein to allow slow drainage of water impounded by the arched hump through the inserts may contain a growth toxic material, in solid or granular form which releases a substance toxic to the growths when rainwater runoff passes into the confined space and over the material and thereafter flows out down the roof.

A substance delivery device includes a combustible paperboard strip and at least one substance toxic to insects and a perfume. The delivery device can take the form of a coil and includes a flexible backing sheet for supporting the combustible paperboard strip. The flexible backing sheet is not capable of combustion. Additionally, the material of the paperboard strip can include a combustion promoter.

The invention discloses active energy porcelain, a preparation method and a second-boiling type slightly alkaline fresh boiled water electric heater. The active energy porcelain consists of the following materials in percentage by weight: 10-50% of tourmaline powder, 10-30% of medical stone powder, 1-10% of intermetallic compound powder, 1-15% of calcium sulfite powder and 20-40% of boron-silicon glass powder. Through adopting the invention, the treated water has the advantages that the water does not contain any substance toxic or harmful to human body and with peculiar smell and is rich in mineral substrates necessary to human body, the content of mineral substances is moderate, the PH value shows slight alkalinity, and the water is energetic micro-cluster water and has the media nutrition physiological function of water, namely the dissolving capacity, seepage force, diffusion force, metabolism force, emulsifying force and the like are superior to those of various types of drinking water on the market. The second-boiling type slightly alkaline fresh boiled water electric heater disclosed by the invention also has the advantages of simple structure, strong practicability and operability and great market prospect.

The invention relates to a permanent hair dye prepared from natural plant-derived dyes and enzymes, which consists of the following two components: Agent I (ointment, pH 6-10) and Agent II (powder). Agents Ⅰ and Ⅱ provide dyes and enzymes respectively. After mixing, they form brown to black dendritic polymer precipitates, which can dye hair into brown or black. The permanent hair dye has strong adhesion to hair fibers, natural color and no irritation to skin. Among them, agent II adopts spray-drying microcapsule technology, which effectively solves the problem of poor stability and short shelf life of the enzyme, which is easily affected by environmental factors such as light, heat, oxygen, humidity and pH value due to its active nature. The prepared enzyme powder has good functional properties, stable storage and convenient use. The hair dye of the invention is a permanent hair dye, does not contain aniline toxic substances, is harmless to human body, and does not produce toxic substances to human body during the hair dyeing process, is very safe and has good dyeing effect.
