METALAMINE CARBOXYLATES AND THEIR USE AS PRESERVATIVES

Material and method for treatment of timber

A material and method for treating timber. The material comprises a preservative and a carrier. The carrier is selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood. By providing a carrier which is mobile within the wood, the timber has a ‘self healing’ effect wherein the carrier/preservative migrates to any freshly cut or exposed surface of the wood to thereby redistribute and treat such a surface within the preservative and hence maintain integrity of a treatment envelope surrounding the wood.

Micronized wood preservative formulations

Wood preservative

- 8 - O.Z. 0975/00056 Abstract of the Disclosure: Wood preservatives based on a copper compound and an aliphatic carboxylic acid and additionally containing a polyamine, and a method for preserving wood with these preservatives.

Stable wood preservative formulations

Stable wood preservative formulations comprising an amine copper complex, at least one azole compound selected from the group consisting of tebuconazole and propiconazole, a cationic surfactant of formula (I), and an isothiazole-based mold inhibitor, are provided. The weight ratio of the cationic surfactant to the at least one azole compound is from 1:1 to 15:1. The azole compound remains stable in solution and does not phase separate over the course of 15 days to 365 days while the formulation is stored at a temperature of 0°C to 50°C. The wood preservative formulations exhibit long-term stability and remain homogeneous, without the need for (see formula I)

Permanent decrease of wood hardness

A wood article is submitted to a vacuum in an autoclave to remove air that it contains. Then, a solution which contains a water-soluble cross-linkable prepolymer, a polymerization initiator and optionally a wood preservative is introduced into the autoclave. Polymerization to form a polymeric network in the wood article is carried out in an atmosphere which may be substantially free of oxygen, while the optionally present preservative is chemically fixed to the wood. The result is a wood article with a permanently reduced hardness and an increased moisture content at equilibrium.

Microbicidal compsns. for protection of technical materials including wood - contain synergistic mixt. of phenolic cpd. and pyrithione deriv,

Microbicidal compsn. comprises at least phenolic active agent (I) and at least on pyrithione deriv. (II). (B) active agent compsn. comprises 2-phenylphenol (Ia) and/or a metal salt of (Ia), and 2-mercapto-pyridine-1-oxide (IIa) as the Na and/or Zn salt. Pref. the compsn. (A) the phenolic active agent is (Ia), 4-chloro-3-methylphenol and/or 2-benzyl-4-chlorophenol and/or metal salts of these. The other agent is (IIa) or 2-hydroxy-pyridine-1-oxide and/or the Na and/or Zn salts of these. The compsn. (A) also contains diluents and/or binders or fixers, and opt. siccatives, UV-stabilisers, colours, pigments, process additives, fungicides, and insecticides. USE/ADVANTAGE - Used in protection of wood (claimed). The use of compsn. (B) in protection of technical materials in general (e.g. paper prodn) is also claimed. The compsns. of cut wood. The active agents set synergistically and are ecologically favourable over highly halogenated cpds. The compsns. may also contain insecticidal cpds.

Magnetic power system for low-friction transportation of loads

ABSTRACT OF THE DISCLOSURE The invention resides in a magnetic force system for frictionless transportation of loads, with at least one magnet (1) secured to the load (7), the magnet being arranged with respect to a ferromagnetic support profile (2). It is important that the magnet (1) be arranged with respect to the profile (2) such that the pole surfaces of the magnet (1) cooperate with at least one vertical profile wall, and are essentially parallel to that wall. A particularly good embodiment is obtained by providing magnets on both sides of a profile wall (2), the magnets having identical poles toward the wall (repulsion principle). Longitudinally, the magnets are arranged in pairs and are close-circuited in pairs by a ferromagnetic plate (4).
