Patent GB-781628-A (GB)
Title: Granular compositions and process for the preparation thereof
Inventor: SCHAAFSMA BERNARD RICHARD
IPC: C11D3/06
Filed: 1955-07-08
Abstract: Granular detergent compositions are produced by forming a flowable paste from (a) a granulating agent (which may be a non-ionic detergent) consisting of a polar organic compound having alcoholic hydroxyl as the only terminal polar radical and a molecular weight of about 150 or greater; (b) water; and (c) an alkali-metal inorganic salt in a hydratable form, present in a quantity sufficient to take up substantially all the water as water of hydration.  The paste is mixed and aerated until semi-solid nodules have formed, and is then quiescently aged to produce a rigid friable mass of coherent, apparently dry, spheroidal agglomerate granules.  Compounds suitable as granulating agents include the polyalkylene glycols and polyglycerols and their derivatives, such as their mono-alkyl ethers and thioethers, alkylphenol monoethers and monoesters of fatty acids, alkanolamides of fatty acids, fatty alcohols and polymeric alcohols such as polyvinyl alcohol.  It is preferred to use the surface-active polyoxyethylene condensates from hydrophobic compounds containing at least about 8 carbon atoms, the condensates containing 6-30 ethenoxy groups per molecule, such as the alkyl phenol or tall oil condensates.  Examples of the alkali metal salts to be used are sodium and potassium sulphates, sodium carbonate, sesquicarbonate and bicarbonate, lithium perchlorate, borates such as lithium metaborate and sodium perborate, and phosphates such as pentasodium tripolyphosphate, tetrasodium pyrophosphate, and mono-, di-and tri-sodium and lithium orthophosphates, all of which form stable hydrates at room temperature.  It is preferred to use Type II pentasodium tripolyphosphate and soda ash in ratios of from 1:4 to 4:1.  The ratio of alkali-metal salt to non-ionic detergent is usually between 35:1 to 2:1, and the ratio of alkali metal salt to water is generally between 8:1 and 2:1.  The compositions may also contain 3-14 per cent of sodium silicate, and may also include anionic detergents.  Such optional additives as dyes, pigments, foam or detergency improvers, sequestering agents, foam depressants, wetting agents, water-treating agents, bleaches, corrosion inhibitors or anti-redeposition agents may also be included.

Title: Improvements in or relating to electronic data-manipulating apparatus
IPC: G11C19/04
Filed: 1963-05-20
Abstract: 962, 095. Electronic shift registers; counters. MINNEAPOLIS-HONEYWELL REGULATOR CO. May 20, 1963 [May 22, 1962], No. 19993/63. Headings G4A and G4C. A shift register comprises a number of bistable electric circuits A2-A7 which after resetting can receive input data at the input S of A7. The transfer means between the circuits comprises 12 magnetic cores SC1-SC12 with two saturating windings (e.g. 16, 18) on each. When one or both of these windings on a core is energized from the ouputs A2-A7, A2-A7 then a clock pulse from driver 12 has no effect, but if neither is energised the core will be switched to provide an output on one of lines SWA2-SWA7 to reverse the state of the corresponding flip-flop and hence shift the data to the left in A2-A7 (the logical equations given in the Specification make this action clear). By the use of twice as many cores (i.e. four per flip-flop) and a left right control flip-flop also controlling windings on the cores, the register may be enabled to shift left or right.

Patent GB-371236-A (GB)
Title: Improvements in or relating to the manufacture of alumina and compounds thereof
IPC: C01F7/46
Filed: 1931-07-16
Abstract: Argillaceous materials such as kaolin or clay are calcined in vacuo below 900 DEG  C. for such time that they are not rendered insoluble in sulphurous acid, and are then extracted with aqueous sulphurous acid preferably at elevated temperature and under pressure. Calcination under reduced pressure may be preceded by heat treatment at atmospheric pressure to expel a portion of the water of constitution.  The extraction is preferably carried out by consecutive treatments with portions of the total quantity of sulphurous acid used.  After extraction, and with or without separation of undissolved residue, the sulphurous acid is completely expelled to precipitate a mixture of alumina with some silica.  The initial material may be pretreated to remove iron, calcium, magnesium, or sand; and to avoid the detrimental presence of sulphuric acid ferric iron should be absent, the water employed be substantially free from air, catalytic materials such as selenium and copper be absent, and the sulphurous acid be stabilized if necessary by the presence of glycerin or phenols. In one example, a clay is heated first at 600 DEG  C. for ten minutes at normal pressure, and then for ten minutes at 700 DEG  C. in high vacuum.  Extraction is effected under pressure at 170 DEG  C., the residue separated, and sulphur dioxide expelled to obtain a precipitate comprising alumina and some silica.  In a second example, a clay is heated in high vacuum at 620 DEG  C. for twenty minutes and extracted under pressure at 100 DEG  C. in two stages, the sulphurous acid being expelled from the solutions obtained to precipitate the alumina with some silica. Specification 371,307 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter: the heat treatment of the kaolin &c. at atmospheric pressure; and separation of silica from the precipitate comprising alumina and silica by redissolving the mixture without drying, and preferably without ageing, in sulphurous acid, gradually heating the solution say to 140-175 DEG  C. under conditions preventing escape of sulphur dioxide until silicic acid coagulates, the solution being left in contact with the precipitate preferably until cool, when the aluminium bisulphite remaining in solution is separated say at 80 DEG C. and aluminia precipitated therefrom by expelling sulphur dioxide. Alternatively the solution may be heated in a closed vessel the gas space of which is large compared with the space occupied by liquid, so that a limited escape of sulphur dioxide occurs during heating and reabsorption occurs during cooling.  In the heating step, incoming solution may be preheated by the hot liquid being discharged.  This subject-matter does not appear in the Specification as accepted.
