Abstract: 265,418. Menzies, W. C. April 7, 1926. Upward-current classifiers.-Coal or like material is delivered from a shoot 6 into a tank 1 between an adjustable baffle 10 and the rear wall 2 of the tank. The tank has a transversely extending intermediate wall 15 above which a plate 17 extends between the side walls of the tank, the opening between the wall 15 and the plate 17 being controlled by an adjustable plate 20. The coal descends on to the imperforate, forwardly inclined, elevated portion 11 of a screen plate 11<a> extending between the rear wall 2 and the intermediate wall 15 and comprising a perforated steeply inclined portion 12, a perforated, less inclined part 13, and an imperforate front portion. A steady stream of water is forced through the screen from the chamber below by a pump 27 supplied from a tank 25, an adjustable deflecting plate 31 being arranged to direct the water through the screen.. The coal is carried above the plate 17 and passes down a slope 50 through a restricted outlet 40, such outlet, being controlled by an adjustable slide 43. Some water passes with the coal through the outlet, the remainder flowing through an opening in the rear wall of the tank on to a screen 42 over the tank 25. The coal passing through the outlet 40 falls on an inclined screen 41 where it is separated from the water which drains through the screens 41, 42 into the tank 25. The heavy impurities are discharged from the screen 11<a> through the opening between the wall 15 and plate 20 on to an elevator 52. Sludge is removed from the tank 1 through opening controlled by valves 63, 64.

Title: Utilisation of vegetable materials containing pentosans
IPC: C09J105/14
Filed: 1923-04-04
Abstract: Vegetable material containing pentosans, such as oat-hulls, is heated with water in a digester to produce a liquid which, after separation from the cellulosic residue, may be used as an adhesive.  In an example 200-225 lb. of oat hulls and 600-700 lb. water are heated by steam under pressure until the temperature reaches temperature until the temperature reaches 180 DEG  C., when the blow-off valve is slightly opened so that about 1 lb. of distillate a minute is collected.  These conditions are maintained for 30-45 minutes, after which the steam is cut off and the pressure in the digester released. The residue is drained and pressed, and the extracted liquid evaporated to adhesive viscosity.  The cellulosic cake is washed, and the washings may be used in place of water in the initial treatment. It is stated that the addition of small amounts of acids, acid salts, and other hydrolysing agents decreases the yield of adhesive.ALSO:Vegetable material containing pentosans, such as oat hulls, is heated with water in a digester; furfural is distilled off during the treatment, and the residue comprises a liquid adhesive and cellulosic material suitable for use as a substitute for wood pulp. In an example, 200-225 lb. of oat hulls and 600-700 lb. water are heated by steam under pressure until the temperature reaches 180 DEG C., when the blow-off valve is slightly opened so that about 1 lb. of distillate a minute is collected.  These conditions are maintained for 30-45 minutes, after which the steam is cut off and the pressure in the digester released.  The p  residue is drained and pressed. The extracted liquid is evaporated to adhesive viscosity in a still, and the first portion of the distillate collected separately.  The cellulosic cake is washed, and the washings may be used in place of water in the initial treatment.  The furfural obtained both from the digestion and the evaporation is re-distilled.  It is stated that the addition of small amounts of acids, acid salts, and other hydrolyzing agents increases the yield of furfural at the expense of the adhesive.

Title: Improved process for the production of sulphuric acid
IPC: C01B17/82
Filed: 1920-03-31
Abstract: 149,648. Schmiedel, T., and Klencke, H. March 31, 1920. Sulpituric acid.-In the production of sulphuric acid by spraying gases containing sulphur dioxide with nitrosyl-sulphuric acid, the reduction of the nitrosyl content of the liquor, which has a strength of 54-58‹ BÚ is prevented, and the power to oxidise the sulphur dioxide maintained by irrigating the gas-stream with nitrosyl sulphuric acid also of 54-58‹ BÚ. and returning the dissolved nitrous gases to the spraying chamber. Sulphur dioxide entering by pipe a, passes through a number of units shown connected in series. The tank k supplies the packed irrigators f<n>, f<2>, and f<1> and the spraying chambers or mixers en, e<2>, e<1> with nitrosyl-sulphuric acid which collects in the receptacle i. and is returned to the tank k by means of the pump l. A portion of the acid is tapped off to a similar mixer b and is denitrated to produce commercial sulphuric acid. To effect the spraying, the rollers p, p<1> &c. as described in Specification 149,647 are used, but other means may be employed. It is possible to have only one mixer and one irrigator in a complete unit, and the acid may be supplied separately to each unit when there are a number working in series. The composition of the acid distributed from the tank is regulated by the addition of water and nitric acid. As the quantity of nitrous gases present depends solely upon the quantity of sulphur dioxide reacting with the nitrosyl sulphuric acid, both gases will be removed from the gas-stream at the same time.

Title: Cement compositions and method of producing same
IPC: C04B24/34
Filed: 1943-06-16
Abstract: A soap of a pine wood resin which is substantially insoluble in petroleum hydrocarbons is mixed with cement, mortar, gypsum plaster, lime, puzzolana, or the like either as a grinding aid during manufacture or immediately prior to mixing.  This is stated to produce a reduction in specific gravity, to facilitate grinding, mixing and positioning, to reduce water-absorption, and to increase resistance to attack by weather conditions and de-icing chemicals. The resin is obtained by treating pine wood, after extraction of the turpentine and pine oil, with a coal-tar hydrocarbon, and treating the residue with a petroleum hydrocarbon such as gasoline or with a mixture thereof and furfural.  The petroleum-insoluble resin is separated and is saponified either by the hot or cold method. Preferably, the pulverized resinous material is dispersed in cold water by means of a small proportion of alkali, a solution of casein in sodium hydroxide, sodium oleate, sodium alginate, sulphonated higher alcohols, sulphonated naphthalenes, or bentonite, or by mechanical dispersion, and concentrated alkali solution is then added; alternatively, the dry resinous material may be added to the alkali solution.  The saponified material may be used in proportions of from 0.005 to 0.30 per cent, and preferably about 0.04 per cent by weight of the cement.
