Title: Preservative composition and process for the use thereof
IPC: B27K3/52
Filed: 1957-09-06
Abstract: The invention comprises a composition consisting of an aqueous solution of (a) a water soluble salt of a polychloro-phenol, (b) a tetra alkali metal pyrophosphate and (e) a salt of a metal having a specific gravity greater than four.  The compositions may be prepared by dissolving the heavy metal salt in water, adding sufficient tetra-alkali metal pyrophosphate to form the phosphato-metallic complex, agitating until the initially formed precipitate has dissolved, adding the water soluble polychlorophenate, and then further agitating the solution. Alternatively the tetra alkali metal pyrophosphate is dissolved in water and the heavy metal salt added, the precipitate so formed dissolving upon agitation.  Any undissolved precipitate is removed or sufficient additional pyrophosphate added to dissolve it, the water soluble polychlorophenate being added at the last stage.  A further alternative is to dissolve the desired heavy metal polychlorophenate in an aqueous solution of a treta alkali metal pyrophosphate. Alkali metal salts of tri-tetra, and pentachlorophenols especially sodium pentachlorophenate, are preferably used.  The preferred pyrophosphate is the tetrasodium salt and specified heavy metal salts are those of copper, zinc and nickel. The proportions of the various components may be varied provided that a sufficient amount of tetra alkali metal pyrophosphate is added to solubilise the heavy metal polychlorophenate.  Suitable proportions are 0,07-3 mols of heavy metal salt, and 0,50/12 mols of polychlorophenate per mol. of tetra alkali metal pyrophosphate.  In examples compositions are made from the following components, tetrasodium pyrophosphate, cupric sulphate pentahydrate, sodium pentachlorophenate, cupric acetate monohydrate, cupric nitrate trihydrate, cupric chloride, zinc sulphate heptahydrate, zinc chloride, di(cadmium chloride) pentahydrate, nickel sulphate hexahydrate, copper pentachlorophenate, and anhydrous copper sulphate, other requestening agents, e.g. sodium citrate and tetrasodium ethylene diaminetetraacetate, also solubilise the copper pentachlorophenate composition.ALSO:Fungicidal, insecticidal and other cellulose-destroying organisms compositions comprise (1) a water soluble salt of a polychlorophenol, (2) a tetra alkali metal pyrophosphate, and (3) a salt of a metal having a specific gravity greater than 4 in an aqueous solution.  The alkali metal salts of the tri tetra and pentachlorophenols and the water soluble salts of copper, zinc, and nickel are preferably used.  The compositions of the invention render fibrous cellulose materials resistant to attack by cellulose destroying organisms.

Class 7(2) In a cylinder head of the kind in which the roof of the combustion chamber 11, Fig. 1, is domed or of pent-house shape and in which are the inlet and exhaust ports 12, 13, respectively, and wherein the axis of each port is inclined to the longitudinal axis 14 of the cylinder, the former at a smaller angle than the latter, the inlet passage 16 as viewed along the axis 14 is so shaped and disposed that its axis, where it meets the plane of the inlet port 12, is at an angle to a radius from the axis 14 which intersects the inlet port axis in the said plane. The area ratio of the two ports 12 and 13 is either 4:3.5, the inlet port 12 being the larger, or 1:1; the inlet port 12 is arranged with one portion of its periphery adjacent the axis 14 whilst the exhaust port 13 is displaced from the axis 14 by 15 degrees so that one peripheral point is adjacent the joint surface of the cylinder head 10. The axes of the inlet and exhaust ports are at angles of 35 degrees and 43 degrees, respectively, to the axis 14. Both the inlet and exhaust passages 16, 18 are Venturi shaped and in plan view the longitudinal axes are curved and where they intersect the plane of the port they are oblique or inclined to a radius of the cylinder; the exhaust passage is of opposite obliquity to the inlet passage so that both passages converge. The sparking plug 24, Fig. 6, is arranged close to the cylinder axis 14. The mouth of the combustion space may either have two segmental shoulders, as shown in Fig. 6, or be of oval configuration with the major axis equal to the cylinder diameter and passing through the centres of the ports, or of circular form with a diameter less than that of the cylinder. In a modification, the combustion space is of pent-house shape and two inlet and two exhaust valves are provided in each cylinder, the area of the inclined surface 31, Fig. 3, in which are located the inlet ports 12, being greater than the other inclined surface 32 accommodating the exhaust ports 13; the junction 33 of surfaces 31 and 32 is on one side of the axis 14. The inclination of surfaces 31 and 32 is such that the axis of the inlet and exhaust ports are arranged at angles of 35 degrees and 44 degrees, respectively, to axis 14, whilst the inlet passages 16, Fig. 4, have their axes, as viewed in plan, inclined to a radius extending between the ports where the axes intersect the plane of the ports, so as to promote swirling of the charge. The corresponding axes of the exhaust passages 18 are parallel to one another and to a radius extending between the ports. When a single exhaust passage is provided with a pent-house shaped combustion chamber, the passage axis, as viewed in plan, may be either oblique or parallel to a cylinder radius meeting the plane of the exhaust port.
