Title: Foot measuring device
IPC: A43D1/02
Filed: 1963-06-05
Abstract: 999,440. Foot-measuring apparatus. T. O. FOURNIER. June 5, 1963, [June 29, 1962], No. 22453/63: Heading G1X. The device is so arranged that on pressure being applied by a foot to a platform 11, Fig. 1, it moves towards a base 10 and in so doing slides a heel block 16 towards a fixed toe block 14 and a movable side block 20 towards a fixed side block 15 and, when the movable blocks 16, 14, contact the foot, indicators 22,23, shew the length and width sizes respectively. When the platform 11 moves downwardly, arms 30, 30a, Fig. 2, thereon rock bell crank levers 25, 25a, anticlockwise and, through rod 41, and spring 42 slide a rack 37 to the right. This in turn rotates a gear wheel engaging the rack 37, the gear wheel being rigid with a pulley 43 carrying a line 50 passing also around pulleys 47, 48, and sliding a bracket 53, slotted to receive a tongue 60 on a slide 56. Thus as the platform 11 moves towards base 10 the slide 56 is moved to the left carrying with it the heel block 16 and actuating, through line 83, Fig. 3, the rotatable length indicator 22. Also, through a pin on a first transverse slide part 67 engaging a slot 61 in slide 56, the part 57 is moved transversely, at first rapidly through the curved part 63 of the slot 61, but subsequently, through sloping part 62 at such relation to slide 56 that part 57 always corresponds to the narrowest shoe fitting for any particular length of shoe. The side block 20 is carried by a second transverse slide part 68 normally moving with part 67 because of springs 71, 72, connecting them together, but, if the foot width is greater than the narrowest fitting, the lost motion afforded by the springs 71, 72, allows part 67 to move whilst part 68 is stopped when block 20 contacts the foot. The relative movement of parts 67, 68, actuates the width indicator 23 carried by part 68, since a member 73 on part 67 is pivoted to a rack 76 engaging a pinion 82 fast with indicator 23.

Title: Process for recovering sugar from sugar-containing substances
IPC: C13B35/02
Filed: 1955-08-15
Abstract: Sugar, or, if desired, a compound of sugar and ammonia, is obtained from sugar-containing substances, such as dried sugar-beet chips, sugar-containing concentrates, e.g. molasses, and residues from the process of the invention obtained by evaporating the mother liquor, by extraction with liquid ammonia, the ammonia extract is mixed with one or more organic solvents and, if desired, a small amount of water, to precipitate selectively the accompanying substances of high molecular weight, these substances are removed by a mechanical method, e.g. filtration, adsorption or centrifuging, and the sugar or a compound of sugar and ammonia is separated from the purified solution by reducing the ammonia concentration.  Separation is achieved by reducing the ammonia concentration to less than 8 per cent by admixture with additional amounts of a different or the same organic solvent as that added to the ammonia extract, or a mixture of such solvents can be used, or the solution is heated to a temperature in the range of 45 DEG  C. to the boiling-point of the solvent or solvent mixture.  A combination of the above method of solvent addition and heating can be employed.  Solvents exemplified are monohydric or dihydric alcohols containing up to 5 carbon atoms, e.g. methanol, ethanol, propanols, butanols, amyl alcohols, glycols, propane- and butane-diols; ketons containing up to 5 carbon atoms, e.g. acetone, methyl ethyl ketone or diethyl ketone, formamide, mono- or die-methyl formamide, mixtures of these solvents, or, if desired, such mixtures in admixture with one or more hydrocarbons, e.g. benzene or toluene, or ethers e.g. tetrahydrofuran.  If desired, any water taken up from the extract by solvent can be removed by choosing one or more solvents forming an azeotropic mixture with water. Partial distillation of the purified solution, i.e. the solution obtained after precipitation of accompanying substances of high molecular weight, removes this water.  Substances such as carbon dioxide, sulphurous acid and/or formaldehyde can be added in amounts up to 2 per cent of the sugar content to the ammonia-solvent admixture and/or to the solvent to be added to the admixture. Surface-active substances, e.g. active carbon, can be added to remove colouring matter before precipitation of the sugar or sugar-ammonia compound.  In three examples the treatment of sugar-beet chips and molasses is described.
Patent GB-860696-A (GB)
Title: Improvements relating to the metallurgical treatment of compositions comprising nickel and iron
IPC: C22B23/02
Filed: 1958-07-30
Abstract: A three stage process for the recovery of nickel, iron, chromium from an ore using a carbonaceous reducing agent and a magnesia bearing basic fluxing material comprises-(1) Reduction with sufficient carbonaceous reducing agent to reduce all the nickel and part of the iron and separating the ferro nickel from the slag containing a major portion of the iron; (2) Reducing the slag with sufficient carbonaceous reducing agent to reduce a major portion of the iron and leave only 3-10% iron oxide in the secondary slag; (3) Reducing said secondary slag with sufficient carbonaceous reducing agent to reduce the remaining iron and the chromium to produce an iron chromium alloy.  A laterite ore may be calcined in a rotary kiln at 1100 DEG C.-1300 DEG C. together with a p  flux of magnesia, magnesia and calcium oxide possibly in equimolar proportions, or dolomite, together with any silica that may be required to give a base-acid ratio of 1-2.25 : 1 calculated as MgO:SiO2, any natural MgO, CaO, or SiO2 in the ore being taken into account.  Some pre-reduction to ferrous iron may be carried out in the kiln by the inclusion of carbonaceous material in the kiln charge.  It is then reduced in an electric furnace maintained at above 1500 DEG C. with sufficient reducing agent to reduce all the nickel and part of the iron to produce a ferro nickel alloy.  Any cobalt present in the ore is retained in the iron rich slag if there is 4-10% of nickel in the ferronickel alloy.  In a second stage the molten iron oxide slag is passed to a second electric furnace where it is reduced to an extent such that as much of the iron as possible is reduced to pig iron without reducing the chromite content of the slag, 3-10% (preferably 6-8%) of FeO being left in the remaining slag after the second reduction.  At this stage the carbon content of the pig iron is kept below 2%.  A third reduction stage in an electric furnace is carried out to produce a chrome-iron alloy containing 20-50% chromium.  If the ore contains little iron, it may be supplemented by additions of ore or scrap.
