Title: Improvements in refining sugar
IPC: C13B30/06
Filed: 1929-03-22
Abstract: 308,686. Baratier Corporation, (Assignees of Spreckels. C. A.). March 26, 1928, [Convention date]. Void [Published under sect. 91 of the Acts]. Drawings to Specification. Saccharine solutions, concentrating and crystallizing.-In refining sugar, solutions are concentrated and caused to crystallize by blowing air or other gas through them at a temperature sufficiently low to avoid loss bv inversion or caramelization of the sugar. Raw sugar is mixed with syrup or sugar liquor in a mingler to form a pasty mass which is passed to an aerator, in which air or other gas is forced through it, thereby agitating the sugar crystals vigorously, freeing them from particles of ash, from molasses and other impurities, and causing evaporation of moisture. The temperature of the aerator should preferably be below 180‹ F. Fresh syrup may be added to the mass in the aerator as the sucrose in the liquid crystallizes out. When crystals of the required size have been obtained they are separated by a centrifugal machine, with or without the addition of small quantities of wash water. The liquid separated contains substantially no crystallizable sugar; the washed sugar is dissolved in water or dilute sugar solution in a melter. After filtration in the usual presses the sugar is crystallized in a second aerator and separated by a centrifugal machine. Syrup from any suitable source may be added to the aerator to maintain the sucrose content of the liquor.

Abstract: 590,686. Moulding composition boards. HEARNSHAW & CO. (MORECAMBE), Ltd., and HEARNSHAW, C. May 23, 1944, No. 9915. [Class 87 (ii)] Composition boards consisting essentially of cement and a wood aggregate are manufactured by making the ingredients into a free-flowing mixture wth water, filling this into a mould, vibrating on a level vibrating table, and removing the mould and maintaining it level until the contents have set. A mould as described and claimed in Specification 590,724 suitable for carrying out the invention consists of a metal base plate 10 stiffened by battens 14 which also act as handles and hardwood or metal sides 11 secured by bolts and wing nuts. The vibrating table carries a frame (Fig. 6) to locate the mould, built up of angle irons 16, timber sides 17 and stiffeners 18 recessed to accommodate the handles and battens of the mould. Fig. 6 shows a stretcher for carrying a mould when full. After filling the mould the surface of the contents is thinly oiled. Vibration causes the wood to rise to the top, forming a cement layer at the bottom to constitute the weather surface of the board. During vibration the material is pressed with a trowel to remove air. A levelling bar is then run across the mould to remove excess material and the mould removed to a stack, two lengths of hardwood being placed in the margins of the mould to act as spacers. After 3 hours the surface is trowelled level to seal it and after 40 hours the the board may be removed from the mould and stacked to mature, a surface finish exposing the wood subsequently being obtained by grinding. The mould sides may be deeper than the finished thickness of board, the levelling bar then having a portion extending below the top of the mould. Reinforcement of wire netting, cane mesh &c. may be included in the board which may also be covered on one or both sides with paper board or waterproof roofing material secured by adhesive.
