Title: Method and apparatus for clarifying lubricating and cooling liquids
IPC: C10M175/04
Filed: 1943-05-28
Abstract: A method of continuously removing solids from contaminated lubricating coolants comprises subjecting the coolants to aeration and agitation in presence of water without the addition of any other froth-promoting reagent, whereby the contaminants are concentrated in the froth, and collecting the froth concentrate. Part of the contaminants may be removed by a preliminary treatment by magnetic separation, tabling or settling.  Examples are given of the use of a "Fagergren" flotation machine in clarifying a "soluble-oil" emulsion of oil and water in metal-working operations, for example, grinding. The Specification as open to inspection under Sect. 91 comprises also the use of frothing reagents for example, pine oil, cresylic acids, fatty acids, soaps and amines, and also the use of wetting agents when settling precedes clarification by flotation, water being a commonly used coolant.  This subject-matter does not appear in the Specification as accepted.ALSO:A method of continuously removing solids from contaminated lubricating coolants comprises subjecting the coolants to aeration and agitation in presence of water without the addition of any other froth-promoting reagent, whereby the contaminants are concentrated in the froth, and collecting the froth concentrates.

Title: Process for the manufacture of hydrogen and carbon monoxide from hydrocarbon gases
IPC: C01B3/40
Filed: 1931-03-20
Abstract: A mixture of hydrogen and monoxide, for use, for example, in the production of methanol or for reaction with steam to produce hydrogen, is obtained by oxidizing methane, natural gas, or other gaseous hydrocarbons by means of metal oxides which are easily reducible under the conditions of the reaction, for example, oxides of iron, chromium, copper, nickel, manganese or zinc; zinc oxide is preferred as being less liable to produce carbon dioxide and water. Molecular proportions corresponding to the reaction CH4+ZnO = 2H2 + Zn are preferably employed, the temperature being 950-1000 DEG  C. In operation, the gas, preheated if desired, may be passed over the heated oxide, or the gas and the oxide may be injected into the heated reaction chamber.  By condensing and oxidizing the zinc produced, the operation may be rendered cyclic.  Two examples are given of the treatment with zinc oxide of a natural gas containing methane together with some ethane and propane at temperatures of 952 DEG  C. and 992 DEG  C.ALSO:A mixture of hydrogen and carbon monoxide, for use, for example, in the production of methanol, is obtained by oxidizing methane, natural gas, or other gaseous hydrocarbons by means of metal oxides which are easily reducible under the conditions of the reaction, for example, oxides of iron, chromium, copper, nickel, manganese or zinc; zinc oxide is preferred as being less liable to produce carbon dioxide and water.

Title: An Improved Process for the Production of Dimethyl Sulphate.
Inventor: BOAKE EDMOND JOHNSON
IPC: C07C303/24
Filed: 1917-06-20
Abstract: 119,250. Boake, E. J., and Durrans, T. H. June 20, 1917. Dimethyl sulphate, methyl hydrogen sulphate, and methyl chloride are prepared by treating methyl alcohol (two molecules) with sulphur dioxide (1 molecule) and chlorine (1 molecule). The two gases are passed, simultaneously or saccessively, into the alcohol; methyl chloride is evolved; the reaction product is heated to drive off dissolved methyl chloride, and is then distilled under reduced pressure ; the methyl hydrogen sulphate is thus converted into dimethyl sulphate, which distils off with that formed in the primary reaction. The methyl chloride may be freed from hydrochloric acid and excess of sulphur dioxide by caustic soda solution or slaked lime, and may be liquefied by cold or pressure. Specification 117,824 is referred to.

Abstract: 1,063,585. Laminates and laminating; making boxes. J. H. FLYNN. March 3, 1965, No. 9133/65. Headings B5D and B5N. Surfaces of paperboard, at least one of which is coated with a waxless polyolefin, e.g. polythene, are laminated together by heating the coated surface in a non-oxidizing environment to melt the polyolefin, heating the other surface, and pressing the two surfaces together. If both surfaces are coated the second is heated to below the oxidizing temperature. The melt-heating of the first surface may be effected by a non- oxidizing flame, applied over the whole surface from a gas burner manifold, and of the second surface by an oxidizing but cooler flame similarly applied. The treated layers are pressed together between a battery of rollers (Figs. 11 and 12, not shown). As applied to cartons which are scored and folded to produce articles of collapsed rectangular section and sealed by a flap on one edge adhered to an adjacent face (Figs. 1-3, not shown), the partially folded and internally polyolefin-coated blanks 22, Fig. 6, forwarded between roller-pressed belts 70, have their flap portions 28, and the areas 26 to which the flaps are adhered, heated by non-oxidizing flames 56, 54 the flames being emitted from slit orifices in burner casings 60 furnished with electrical spark igniters 62, 64.

[Class 112] In a buttonhole-sewing machine, means are provided whereby automatic opening of the work-clamp at the completion of a sewing operation may be prevented if desired. In the arrangement shown, the upper clamp members d are carried on pivoted arms k which are integral with hook-shaped arms f engaging lugs g on a yoke h pivoted to the work-plate c at i. The yoke h carries a crank n, o pivoted to it at p, and a hand-lever q is pivoted to the work-plate c at r and to the crank arm o ; a spring m is attached to the lower arm of the yoke h. By movement of the lever q to the right, the yoke h is forced downwards to pull the clamp arms k down, and the toggle linkage q, o is straightened to hold the clamp closed. As the work-plate completes its travel in the formation of a buttonhole, a lug s on the crank arm o engages the end of a lever t, pivoted at u on the frame and raised by a spring v, to break the toggle and release the clamp; this action may be prevented by depressing the lever t clear of the lug s by means of a hand plunger w. The clamp may be automatically closed by mechanism depressing the lever t to engage the crank arm n and press it down.

Title: Manufacture of ammonium sulphate
Inventor: NICOL WILLIAM LINDSAY
IPC: C01C1/242
Filed: 1966-03-02
Abstract: Powdery ammonium sulphate is continuously produced from ammonia and sulphuric acid by a process comprising (i) adding to a recycling bed of solid ammonium sulphate of moisture content less than 8% by weight an aqueous solution or slurry of ammonium sulphate of water content 13 to 48% by weight, and ammonia and sulphuric acid, of concentration greater than 60% by weight H2SO4, in such proportions and at such rates that substantially ammonium sulphate is formed, that the temperature of the bed of solid ammonium sulphate is maintained below 110 DEG  C., and that the heat of the reaction drives off sufficient water to reduce the water content of the added reactants and the bed to below 5% by weight, (ii) withdrawing from the bed an amount of solid product substantially equivalent to that produced by addition of the reactants, (iii) recycling the remainder of the solid ammonium sulphate.  The following preferable conditions are specified: the bed should contain at least 2 1/2 % by weight of water, and its temperature should be maintained below 65 DEG  C.  The ammonium sulphate solution or slurry should be made by reaction of substantially stoichiometric proportions of gaseous ammonia and sulphuric acid of H2SO4 content 30 to 50% by weight, should contain 15 to 25% by weight of water and be within 10 DEG  C. of its boiling point on addition to the bed.  Reactant ammonia should be gaseous and reactant sulphuric acid should contain more than 80% H2SO4 by weight. Recycling should be accompanied by agitation, which is conveniently achieved in a trough mixer of type described in Specification 1,001,031.
