Filed: 1917-03-01
Abstract: 112,349. Taylor. W. March 1, 1917. Addition to 15375/15. Lenses and curved surfaces, grinding and polishing.-In the application of the method of " terrace grinding " as described in the parent Specification to the formation of spherical surfaces upon glass and like materials, the edge of the abrasive wheel is set so that it moves across the face of the rotating work, there being a slow movement of approach between the work and the wheel, the axes of which are set at the requisite angle to give the required radius. The rough grinding is accomplished with the wheel axis set relatively to the work axis out of one common plane so that the wheel operates to one side only of the axis of the work. The finishing operation is accomplished by the wheel set with its axis substantially in one plane with the work axis. The annular grinding- disk e is formed with a bevelled surface e<2> to give the necessary clearance and an active surface e<3> to give the abrupt step. The disk is carried on a driven spindle f in bearings in a yoke frame h supported on alined pivots i, which are mounted upon a slide rest constructed as described in Specification 15377/15. The frame can be tilted about these pivots by a screw n passing through a nut o on the frame, to move the axis e<1> of the grinding-disk out of the plane of the axle c' of the work-spindle. The rough grinding is accomplished with the axis c<1> set at an angle to the axis of the work-spindle. During the operation, the axis is gradually lowered until, for the finishing operation, it is in the plane of the work-spindle. The axis of the pivots i passes through the axis of the work-spindle at the active point of the grinding-disk. The work-spindle axis may be tilted in place of the grinding-disk axis. A separate wheel may be used for the finishing operation and may be mounted as described in Specification 15377/15, and, in this case, a number of work-spindles may be mounted upon a turret arranged and operated as described in the same Specification.

Title: Manufacture of condensation products from acetylene
IPC: C07G99/00
Filed: 1929-01-30
Abstract: 316,282. I. G. Farbenindustrie Akt.- Ges. July 27, 1928, [Convention date]. Condensation products containing nitrogen and sulphur are obtained when acetylene is passed with an ammonium sulphide, or with a mixture of ammonia and hydrogen sulphide or sulphur vapour, at an elevated temperature over a catalyst consisting of one or more metallic sulphides or metals or compounds which become converted into sulphides under the reaction conditions. The condensation occurs at a temperature of 250- 400 C. and in the substantial absence of steam. 'Catalysts mentioned are the oxides, hydroxides, carbonates, chlorides or sulphides of copper, zinc, aluminium, silver, mercury, chromium, nickel, antimony, manganese, molybdenum, iron and tin. The liquid products obtained by cooling comprise compounds of the pyridine and thiophene series together with bodies of indeterminate constitution containing both nitrogen and sulphur; in admixture they are useful for mineral flotation processes and individually as intermediates. According to the examples, (1) a mixture of ammonia, hydrogen sulphide and acetylene is passed through a heated aluminium chamber containing copper sulphide which has been precipitated on coke or pumice and dried in a current of nitrogen; antimony sulphide, silver sulphide or iron chloride may replace the copper sulphide; the yield of product is increased by using copper sulphide conjointly with nickel sulphide or cobalt sulphide and employing as carrier a metallic oxide or substance of large surface, e.g. zinc oxide, molybdic oxide, iron oxide or silica gel; (2) acetylene, ammonia and sulphur vapour are passed over a heated mixture of copper sulphide and cobalt sulphide mounted on a zinc oxide carrier.

Title: Improvements in and relating to the concentration of aqueous acetic acid solutions by distillation
Inventor: HARTLEY GEORGE ANTHONY RATHBON
Filed: 1951-02-09
Abstract: <PICT:0699358/III/1> Aqueous solutions of acetic acid are concentrated by distilling them in the presence of one of the following solvents: - methoxy triglycol acetate, diglycol diacetate, methoxy diglycol acetate, ethoxy triglycol acetate, dimethoxy triglycol, dimethoxy diglycol.  Water is obtained as distillate leaving a mixture of solvent and concentrated acid, which is then separated by fractional distillation, preferably under reduced pressure.  The molecular ratio of solvent to the water present in the solution is preferably within the range from 1:1 to 5:1.  The process is particularly applicable to the concentration of aqueous solutions containing up to 15 per cent of acetic acid where the usual azeotropic distillation processes are uneconomical.  A 10 per cent aqueous acetic acid solution was passed continuously through pipe 3 into distillation column 1 heated by boiler 2; and diglycol diacetate (1 part by weight per part of aqueous acid) was introduced into the upper part of the column through pipe 4.  The boiler 2 was maintained at a temperature of 120 DEG C, and the top of the column at 100 DEG C.  The vapours from the head of the column were p  passed to condenser 6, and water containing only 0.2 per cent of acetic acid was obtained as condensate.  A mixture containing 9.2 per cent acetic acid, 89.4 per cent diglycol diacetate and 1.4 per cent water collected in boiler 2, and was passed through pipe 8 into column 9. The boiler 10 of column 9 was maintained at 160 DEG C, and the pressure within the column was maintained at 25 mm. Hg. by vacuum pump 14.  A mixture containing 87 per cent of acetic acid and 13 per cent water was condensed in condenser 12, and collected in receiver 15.  A mixture of 99.5 per cent of diglycol acetate and 0.5 per cent of acetic acid collected in boiler 10, and was returned to column 1 via pipe 4.  The second Provisional Specification also refers to the use of diethoxy triglycol as solvent.  Specifications 652,844, [Group IV(a)], and 670,751 are referred to.
