Abstract: A liquid deodorant composition comprising an aqueous solution containing specific 3d transition metal halides is provided. This deodorant composition does not require high facility and operating costs, and can effectively reduce malodors, especially sulfureous and nitrogenous offensive odor substances.

Abstract: A detoxifying agent for use in disposal of noxious wastes that is conducted by solidifying them with cement, consisting essentially of an aqueous solution which comprises as main components (a) small-sized metal cations whose 6-coordination ionic radii are less than 100 pm, (b) medium-sized metal cations whose 6-coordination ionic radii are between 100 pm and 140 pm, and (c) large-sized metal cations whose 6-coordination ionic radii are in excess of 140 pm. This detoxifying agent can provide cement-solidified materials having high strength, substantially free from exudation of toxic substances such as heavy metals, PCBs and dioxins.

Abstract: An improved three-dimensional combination toy may comprise a central part, a plurality of guide canopies installed above the central part to form guide spaces, (the guide canopies being laterally spaced apart from one another such that the spaces between the edges of adjacent guide canopies define guide tracks), seven movable blocks (each provided with a slide piece dimensioned to slide within and be retained by the guide spaces and attached to its block via an inwardly projecting slide leg free to move within the guide tracks) and a fixed block fastened to the central part. Preferably, a slide piece insertion opening is defined (by means of cutouts provided in the relevant canopy corners) at one particular rest position where a particular three of said guide canopies are adjacent to one another.
