Abstract: An apparatus and a method are disclosed with which deteriorated edible oil is regenerated into fresher oil by lowering its oxidation degree. The apparatus comprises an air processor unit comprising a first air flow path configured to have an inlet and an outlet and allow air to pass between magnets positioned in close vicinity with their opposite magnetic poles facing each other, and a second air flow path connected to the outlet of the first air flow path and provided with a far-infrared ray emitter member therein; a pump for pressure feeding air to the inlet to the first flow path of the air processor unit; a length of tubing which is connected to the outlet of the second air flow path of the air processor unit, and one or more air spewing holes provided at the tip of the length of tubing. And the method of the invention comprises bringing the air from the apparatus into contact with the deteriorated oil to be treated.

Abstract: An insecticidal resin coating film comprising a combination of an acrylonitrile and/or methacrylonitrile copolymer resin and an insecticidal component selected from the group consisting of specified compounds exhibits an insecticidal effect, since the compound is kept on the surface of the coating film in a state capable of exhibiting its insecticidal effect for a long period of time.

Abstract: This invention relates to a strippable coating film for use as a masking material serving to create attractively finished boundaries, for example, in multi-color painting of automobiles and the like, as well as a coating method using such a coating film.A coating film containing 1 to 20 parts by weight of carbon black per 100 parts by weight of the resin component present therein is suitable. Especially preferred is a coating film formed of an acrylic emulsion paint and having an adhesion to the substrate of 20 to 1000 g/inch as expressed in terms of 180.degree. peeling strength. It is disclosed that, by equipping a YAG laser with a Q-switching oscillator unit and operating the Q-switch at a pulse repetition frequency of 0.5 to 30 kHz, the coating film can be cleanly cut to achieve an attractive finish in multi-color painting.

Abstract: Disclosed herein is an adhesive composition which contains specific amounts of (A) an aqueous emulsion, (B) a filler and (C) a resin solution of a resinous tackifier dissolved in a solvent and/or plasticizer. The adhesive composition has a fast setting time in adhesion strength and excellent water-proofness and hence produces superb adhesion force even when applied to a fresh mortar base which has been aged insufficiently.
