Abstract: 1358328 Comparing data GOODYEAR AEROSPACE CORP 5 April 1972 [3 May 1971] 15609/72 Heading G4C Contents searches between data words in a store 12 (Fig. 1) and comparand words are performed, bit by bit, to derive tag bits representing the result of the comparison, data words having a predetermined tag-bit array being read out at the end of the search. As described the tag bits are held in a plated wire associative store 12, a selected bit of each comparand and data word being read into word circuits 18, 20, the circuits 20 being set to write if the data bit is of the required value and a bitselect driver being enabled at the appropriate bit time if the comparand bit has the required value so that a tag bit having the value required by the search operation being performed is entered if both these criteria are fulfilled. In the embodment of Fig. 1 the comparand words are stored in a separate store but in the embodiment of Fig. 2 (not shown) a single storage matrix (40) is provided for both comparand and data fields.

Title: Process for the production of alumina and magnesia
IPC: C01F7/26
Filed: 1941-12-04
Abstract: 553,034. Aluminium and magnesium compounds. STEIN & CO., Ltd., J. G., HYSLOP, J. F., and MACKENZIE, R. Dec. 4, 1941, No. 15614. [Class I (iii)] Pure alumina and relatively pure magnesia are obtained from aluminium sulphate (which may be a product of the treatment of clay with sulphuric acid) and calcium-magnesium carbonate rock by a series of steps in which the finely ground rock is added to aluminium sulphate solution heated to over 50‹ C. to produce aluminium hydroxide, calcium sulphate, magnesium sulphate and carbon dioxide ; the magnesium sulphate solution is separated and concentrated, and the crystals heated to obtain magnesium oxide. The mixed precipitate of aluminium hydroxide and calcium sulphate is heated to above 1200‹ C. to give calcium aluminate and sulphur dioxide and the calcium aluminate is treated by known methods to give alumina, e.g. by reaction with sodium carbonate and precipitation from the sodium aluminate.

Patent GB-499566-A (GB)
Title: Improvements in and relating to the manufacture of alkali phosphates
IPC: C01B25/30
Filed: 1938-05-26
Abstract: Tri-alkali phosphates, especially tri-sodium phosphate, are made by heating together crude calcium phosphate and alkali hydroxide or carbonate so that CO2 is excluded or if evolved, is removed as quickly as possible, and extracting the final product.  The crude phosphate may be previously purified by treating with HCl gas and chlorine at an elevated temperature thus vaporizing impurities; or by ignition with a small quantity of caustic soda in the presence of an oxidizing agent and leaching.  Sufficient alkali is used to convert the phosphate to the trialkali compound and also to react with any impurities.  The alkali may be added as a concentrated solution to form a paste which is dried or may be mixed in the form of a powder. The mixture is heated in an externally heated furnace or in an electric furnace, to about 4-500 DEG  C. if a caustic alkali, or 8-900 DEG  C. if the carbonate is used; in the latter case steam or other inert gas is led through the furnace to remove CO2. The product is leached with preferably a little boiling water, the phosphate being crystallized out.  The mother liquor may be re-used for leaching.  Examples are given using caustic soda, soda, and potash. The residue from the leaching process can be used as a fertilizer and the undecomposed phosphate therein is fully citrate soluble.

Abstract: Articles (3), for example flat tubular-bag packs, are conveyed on a conveyor band (1), and they are to have prescribed spacings (A). Arranged above the conveyor band is a horizontal disc (5) which is driven by the latter and to which a plurality of slides (7) are fastened adjustably. The slides (7) are set in such a way that, during operation, they always run through between the articles (3) when these are at the prescribed spacings (A) on the band (1). However, if this spacing is smaller or if two articles are joined together as a result of the faulty working of a preceding apparatus, the faulty articles are pushed away from the conveyor band (1) by one of the slides (7). The apparatus is of simple construction and works reliably even at high conveying speeds. <IMAGE>
