Patent GB-407035-A (GB)
Title: Improvements in or relating to the manufacture of cyclic ethers
IPC: C07C41/00
Filed: 1932-09-01
Abstract: Cyclic ethers are produced by heating glycols or polyhydric alcohols combined with or mixed with metal oxides such as alkali and alkaline earth metal oxides, preferably in the presence of hydrochloric acid, and/or other condensing agents such as calcium chloride or sodium chloride.  The reaction may be effected in presence of an inert liquid of high boiling-point such as tetrahydronaptthalene, decahydronaphthalene or diphenyl, and nitrogen, carbon dioxide or other gases or vapours may be passed through the reaction mixture to effect agitation.  The reaction may be effected in presence of a liquid forming an azeotropic mixture with water or with the ether, and if desired the inert diluent may be one that can entrain the ether.  Or an azeotroping substance may be added to the vapours leaving the reaction vessel so that the ether can be fractionally condensed while the water and entraining agent remain in the vapour state.  Alternatively the ether may be separated by passing the vapours into a liquid maintained at a temperature between the boiling points of the ether and water, or into a liquid that will dissolve the ether but not water, or the vapours may be passed over water-binding substances, preferably after first fractionally condensing the bulk of the water.  The vapours may be passed over substances such as sodium carbonate or calcium hydroxide to neutralize hydrochloric acid, or the neutralization may be effected after condensation.  In examples, (1) a mixture of calcium glycerate and diphenyl is treated with hydrochloric and at 190-200 DEG  C.; (2) a mixture of calcium glycerate and glycerol is heated at 240-280 DEG C. while stirring.  Instead of glycerol, other polyhydric alcohols such as erythritol or ethers thereof containing at least two free hydroxy groups in the form of metal salts or mixtures with metal p oxides may be used.  Or mixtures of salts of glycol and glycerol or of glycol and an ether of glycerol may be employed. Specification 396,761 is referred to.

Title: Granular material classifier or purifier
IPC: B07B4/02
Filed: 1941-04-30
Abstract: 549,019. Centrifugal separators. SMITH, W. N. April 30, 1941, No. 5615. [Class 23] Mixtures of solid granular materials are separated into components, each consisting of particles of the same weight, by throwing the mixtures in an umbrella-like shower from a conical cup rotating on the axis of a semispherical dome; the particles are thrown outwards according to their weight and are collected in annular troughs. The machine may be used in the milling process to free middlings from bran impurities and to classify them. Two units are shown in Fig. 2, arranged in a cylindrical casing 6 with two domes 8 arranged above the unit. An axial shaft 11 is supported in upper and lower bearings 9, 10 and is driven by an electric motor 12 through belts 14, 20 and a speed control device 15 with a manual control lever 16. The shaft carries the feed cone 17 of each unit to which the material mixture is supplied by the pipes 53, 87. Each unit has a stationary table 22 supported by the casing, and this has circular grooves in which run the circular rings 31 of the revolving collector 26, Fig. 4, which also has radial spokes 28, 29. An adjustable air sleeve 40 has an upper conical member 41 outside the feed cone 17. This upper part telescopes into a lower member 43 at the bottom of which is arranged a fan 34 secured to the cone shaft 11. The material is supplied to the pipe 53 and opens the valve 55 ; it then passes to the feed cone 17 by way a sleeve 51 which can be adjusted in position by means of the screw 52. The rotating cone throws the material from its rim, and it follows a path which spreads almost to the dome 8. The materials are classified during their passage through the air and drop into the cells in the collector 26, the revolution of which carries the separated materials to a slot in the table 22. They drop through this slot and are directed between partition valves 57, 58, 59 with spring pressed tops, to discharge pipes 92, 93, 94, 95. Air currents are drawn by the fan 34 through the ports 66 in the dome 8 and through the falling fountain of materials; it then passes through the space between the feed cone 17 and the air sleeve 41 while a small portion passes through the ports of the telescopic sleeve. From the fan it passes out by a discharge pipe through the casing. The passing air is of a small volume and low velocity to prevent the formation of dead-air space.

Abstract: 933,337. Mixing solids with liquids in flow. KLOCKNER-HUMBOLDT DEUTZ A.G. Feb. 17, 1960 [June 1, 1959], No. 5627/60. Class 86. [Also in Group XXIX] In a method and apparatus for regulating the solid content of a pulp or slurry, so as to supply a constant quantity per unit time of slurry of a constant solids content and constant grain size, coarse and fine grain dense slurries are supplied from concentrators 30, 30<SP>1</SP> in constant proportions to an intermediate tank 37, thence via a pipe 55 to another intermediate tank 56, and from there through pipe 68 to a mixer 69, to which is also supplied dilution water from pipe 73. The final mixture thus formed flows up a tube 76 having two dip-tubes 77, 78 supplied with compressed air at constant pressure. The pressure set up in the pipes 81, 82 is a measure of the depth of penetration in the tubes and, with a predetermined difference of penetration, the difference in pressures is a measure of the specific gravity of the slurry. The measured value controls the inflow of slurry and carrier liquid into the mixer 69 through the valves 90, 92 which move in opposite directions in such a manner that the sum of the flows remains constant. A dip-tube 38 in the tank 37 controls the valves 35, 35<SP>1</SP> so that the level in that tank remains constant while another dip-tube 57 in the tank 56 provides an over-riding control of the valves 35, 35<SP>1</SP> if the level in the tank 56 should rise too high. The apparatus is primarily intended for use in the separation of coal by flotation.
