Title: Production of crystalline glucose
IPC: C13K1/10
Filed: 1961-02-17
Abstract: Production of crystalline glucose comprises preparing a low-dextrose starch conversion liquor from starch and water in the presence of alpha amylase or strong mineral acid, further hydrolysing with amyloglucosidase until the glucose content of the solids of the liquor is not less than 83%, concentrating the further hydrolysed liquor to a % dry substance which varies inversely with the glucose of the solids of the liquor according to the table .% glucose of the solids.% dry substance .82.0-85.9.60-87.2 .86.0-89.9.59-86.2 .90.0-92.9.58-85.2 .93.0-94.9.57-84.2 .95.0-95.9.56-83.2, adjusting the temperature of the concentrated liquor to a crysallization temperature in the range 20-54 DEG C., seeding the liquor with crystals of glucose, controlling the glucose supersaturation, i.e. the ratio of observed glucose concentration to the known equilibrium concentration of glucose in water at the same temperature, to 1.02-1.20 by regulation of the liquor temperature, and separating the mother liquor from the crystalline glucose formed.  The starch may be from maize, milo (sorghum), wheat, potato, rice or tapioca.  Sources of the amylo-glucosidase are culture broths of the moulds Rhizopus delemar, selected strains of Aspergillus niger, A. phoenicis and A. oryzae.  The production is preferably conducted continuously, starch paste thinned by the alpha amylase or acid being mixed with the separated mother liquor after it has been treated with ion-exchange resins to remove enzymes and reduce its mineral content sufficiently to maintain the ash/total solids of the syrup fed to the glucose crystallizing step at less than 3%, and the mixture being treated, after saccharification by the amyloglucosidase, with an absorbent to remove colour bodies and other soluble impurities.  U.S.A. Specifications 2,531,999, 2,557,078, 2,567,000, 2,717,582, 2,881,115 and 2,893,921 are referred to.

Patent GB-1044254-A (GB)
Title: Process for the preparation of potassium metaphosphates
IPC: C05B13/06
Filed: 1964-02-13
Abstract: Potassium metaphosphate, (KPO3)n, is prepared from phosphoric acid and potassium chloride by reacting these compounds on the surface of a fused salt bath, consisting essentially of the final product of the reaction, which is maintained near its melting point by means of heat supplied partly externally to the bath and partly within the bath. KCl and phosphoric acid of P2O5 content desirably more than 25% are fed in substantially equimolar proportions on to a liquid (KPO3)n bath, contained in a tank furnace lined with refractory material and insulated only on the walls in direct contact with the bath. External heating may be supplied by a burner placed between the bath surface and furnace roof and/or by a radiant heating roof.  Internal heating, provided by applying a voltage between graphite electrodes preferably totally immersed in the bath, comprises, e.g., 5 to 50% of the heat required to maintain the bath temperature between, say, 560 DEG  to 850 DEG  C.  The molten (KPO3)n produced leaves the tank by overflow and a water-soluble product is obtained by strong cooling, e.g. on a water-cooled metal belt-conveyer or rotary drum.  The solid (KPO3)n is then ground and screened.  Other cooling procedures include feeding the molten product on to a spraying apparatus whereby cooling and granulating are effected together. The gases leaving the furnace, containing HCl, may be passed into heat exchangers, the heat recovered being used to preheat the combustion air of the burner, and thence to a conventional absorption device for obtaining aqueous HCl. An excess of KCl may be used to obtain a (KPO3)n/KCl fertilizer and sulphuric acid may be incorporated with the reactants to yield a K2SO4-containing product. The melting temperature of the (KPO3)n bath may be lowered, e.g. by metal oxide impurities present in the phosphoric acid used or by addition of compounds such as K2SO4, metal oxides and metal salts.

Title: Improvements in the method of manufacturing reinforced concrete posts, beams or pipes and in apparatus therefor
IPC: B28B23/18
Filed: 1949-03-08
Abstract: 681,354. Reinforced concrete. WHITEHEAD, R. April 19, 1950 [March 8, 1949], No. 6214/49. Class 20(iv) [Also in Group V] Reinforcement in the form of a tapered cage W is suspended by means of a bolt D from a cross member E fixed to pillars F. A tapered internally-lubricated mould G is then raised by electrically operated hoisting mechanism from the position shown, the mould having bearings H which slide on the pillars F, and is fitted over the cage and secured thereto by means of a rod J depending from the cage, a nut K and a bar, or by means of a pin passing through the mould and cage base B. The mould is then filled with semi-dry concrete, vibrated by means of electrical vibrators (M, Fig. 2, not shown) mounted on the mould and released by undoing nut K and removing the bar, whereupon the mould is pressed downwardly by hand or by hydraulic rams and drops onto a cushion N, leaving the reinforced concrete article (post) hanging on the cross member E. The post may then be attached to a carriage on an overhead runway and removed to a drying room or suspended by the reinforcement from a drying frame. The reinforcing cage comprises two end-plates B, C, through which rods A are passed, the ends of the rods being bent over, and transverse rods A<SP>1</SP>. The weight of the mould stresses the rods. The rods are weakened at P, and after the post has been dried the rods can be twisted to break them off at P, the holes left in the ends of the post being filled with concrete. The plate B closes the lower end of the mould and carries a block Q which has a hemispherical recess R which shapes the end of the post. Holes may be formed in the post by initially disposing withdrawable pins in the mould. The pillars F may be disposed in a pit, the base of the raised mould being at ground level. A rectangular-section post may be made by using a mould having four sides secured together by pivoted cams, Figs. 10 and 11 (not shown). In making a rectangularsection beam, cores may be inserted along opposite sides of the mould to give the beam the desired shape, the cores sticking to the beam when the mould is pressed off and being removed later. Pipes may be made by using a core.

Abstract: 1,001,673. Evaporating liquids in film-form; distilling saline water. GENERAL ELECTRIC CO. Feb. 15, 1963 [March 1, 1962], No. 6243/63. Heading BIB. [Also in Division F4] Liquid is evaporated by causing it to flow down one side of a metal wall, which is:  heated on the opposite side, the wall having vertical corrugations with a pitch P of from 0À05-0À5 inch, and of height H from 0À05- 0.25 inch, and the length L of the wall compares to the height H in the ratio of 50:1 -  5000:1. Initially the liquid flows down the grooves 14; the vapour-bubbles are formed which splash the liquid over the adjacent ridges in a thin film. Vapours may be condensed on a similar heat-exchange wall. The distillation apparatus for saline water shown in Fig. 3 is divided into three compartments 26, 28 and 30 by two corrugated walls 22 and 24 of the form specified above. Steam, from a boiler or a turbine, is supplied through pipe 32 into compartment 26 so that the left-hand side of wall 22 is heated. Preheated saline water, supplied to compartment 28 through pipe 36, flows down the right-hand surface of wall 22. About 75% of this water evaporates ; and the vapours are condensed on the lefthand side of wall 24. Distilled water is withdrawn through pipe 42. The right-hand side of wall 24 is maintained cool by flowing saline water, supplied through pipe 46, over it. The heated saline water, withdrawn through pipe 50, is supplied to inlet-pipe 36. Concentrated salt solution is withdrawn through pipe 40. The length of wall 22 and the rate of supply of saline water are chosen so that no precipitation of salts will occur from the distilland. If desired, the vapours evolved from the saline water may be condensed on the opposite side of the same heat transfer wall from which they were evolved, provided a sufficient elevation in pressure is first given the vapours.
