Title: Process for degasifying and killing liquid steels
IPC: C21C7/06
Filed: 1937-03-25
Abstract: Molten dephosphorized steel is degasefied and killed by introducing in the steel, while it is being poured into a receptacle, a reducing mixture, generally pulverised, comprising one or more reducing agents capable of fixing oxygen, and, if desired, of evolving heat and one or more substances capable of producing an evolution of gas thus ensuring ebullition of the bath and the formation of a slag with the reducing agent &c.  The mixture may be placed in the receptacle and the steel poured on to it or may be introduced into the jet of metal while it is being poured.  Simple or complex alloys such as silico-calcium, silico-aluminium, silico-titanium or ferro-silicon may be used as the reducing agents and the other substances alkaline compounds such as sodium or potassium carbonate, caustic soda or potash. Compounds such as siliceous sand, bauxite, fluorspar or ilmenite, which stabilize and slow down their decomposition, may be added to the alkaline compounds.  Elements such as nickel, chromium, carbon, manganese, or silicon which it is desired to incorporate in the steel may be added to the mixture either in the form of alloys or of compounds.  In one example, a mixture of 2,8 kilograms of silico-calcium, 3 of sodium carbonate and 0,8 of white siliceous sand is placed in a ladle and a metric ton of molten steel poured on to it.  In another example, the mixture comprises 2,6 kilograms of silico-calcium, 3 of sodium carbonate 0,8 of white sand and 3 of ferro-chromium containing 0,1-0,2 of carbon.

Title: Improvements in or relating to collecting mechanism for rod-shaped articles
IPC: A24C5/354
Filed: 1940-05-18
Abstract: 541,998. Conveyers. MOLINS, D. W., RUAU, F. F., CHOWN, S. R., and MOLINS MACHINE CO., Ltd. May 18, 1940, No. 8878. [Class 78 (i)] [Also in Group, XVII] A collecting mechanism for cigarettes or other rodshaped articles is of the kind in which the articles, during movement in a direction transverse to their axes, are delivered into a receptacle R, which is, during the filling operation, moved automatically in one direction in such a manner that articles are delivered first into one end of the receptacle and afterwards to positions along the length of the receptacle, the articles being directed into the receptacle by a downwardly inclined guide 52 projecting into the receptacle. In order to level the articles in the receptacle, an article-distributer 11 is arranged to move downwards into the receptacle with a component of movement in the direction of movement of the latter, so as to move articles in the receptacle away from the guide 52 and towards the leading end of the receptacle. As shown, a catcher band 4 receiving cigarettes from a continuous-rod machine delivers them past a counter-weighted flap 7 and over the guide 52 into the receptacle R, which is of the form described in Specification 541,999 and has slots 100 allowing the passage of the receptacles past the guide 52. The cigarette distributer 11 comprises paddles having ribs 54 and carried by a rotatable support 10, the axis of which is slightly below that of the roller 5 of the catcher band 4, and the flap 7 is slotted to allow the paddles to clear it. The flap 7 and the guide 52 also have ribs 55, 56 parallel to the bottom of the receptacle R, and levelling guides 61 are provided above the receptacle. The receptacles are carried in endwise abutting relation by conveyer chains 14, 15 running on sprockets 16, 17 rotatable about vertical spindle 22, the lower sprocket 16 being driven intermittently by means of a ratchet wheel 24 and pawls 25, 26 eccentrically mounted on an electrically-driven spindle 27, from which also the distributer support 10 is driven through a belt 36. The receptacles are connected to the chains 14, 15 by U-shaped straps 37 supporting cross-bars 38, 39 to which are secured members 40, 41 into which the receptacles fit. Stops 42, 43 on the receptacles limit movement of the receptacles relatively to the conveyer. To support the weight of the receptacles, bars 46 carried by the cross-bars carry rollers 47 running on the base 48, and a roller 49 on the bottom of each receptacle engages a track when the receptacle is being moved around the sprockets 16, 17. If the supply of cigarettes on the band 4 ceases, the driving motor 201 is stopped by a detector device comprising a counterbalanced flap 57, the spindle 58 of which carries a mercury switch 60 in the circuit of the motor. In order to increase the speed of the conveyer chains when a second receptacle is moving into position to receive cigarettes, the motor 201 may be connected to a rheostat controlled by a feeler as described in Specification 542,022.
Patent GB-1094778-A (GB)
Title: Photometric method for the determination of manganese in alloys containing chromium and vanadium
IPC: G01N33/20
Filed: 1965-03-02
Abstract: Mn in alloys is determined by dissolving said alloy in nitric acid, oxidising Mn present to MnO4- with bismuthate, forming tetraphenyl phosphonium permanganate, extracting the latter and subjecting the extract to photometric determination. If V is also present, the solution to be subjected to extraction should contain 1-3.5M H2SO4: if.Cr is present it should contain 2.5-3.5M H2SO4.  In the described procedure, an alloy is dissolved in conc.  HNO3, evaporated to dryness (in the case of ferroalloys H2SO4 being then added and the product heated to destroy any organic material due to any C present), the residue redissolved in water, dilute HNO3 added and oxidised with bismuthate.  The excess bismuthate is filtered off and NaOH aq. added until the precipitate formed redissolves.  H2SO4 is added to the final molarity referred to above.  Tetraphenyl-phosphonium chloride solution is added and the corresponding permanganate extracted with chloroform or dichloroethane.  Na2SO4 (solid) is added to the extract to clarify and photometry is performed with a green filter.

Title: Improvements in or relating to methods and devices for testing for the presence of water in suspension in other liquids
Inventor: JOYCE JOHN RUSKIN
IPC: G01N31/22
Filed: 1956-03-22
Abstract: <PICT:0806928/III/1> The presence of small amounts of water suspended in fluids, e.g. aviation fuels, is detected by bringing the liquid into contact with a water-soluble powder, which changes colour, and then with a water-absorptive medium.  The preferred form consists of a filter paper coated on the up-stream side with a water-soluble dye, ferric thiocyanate, or a mixture of salts developing a colour, e.g. prussian blue.  Preferably the impregnated filter paper is mounted in a transparent capsule, and included in a by-pass circuit attached to the fuel supply pipe.  A suitable capsule comprises two parts 1, 2, Fig. 1, made of methyl methacrylate, which may be screwed together with the sheet of filter paper 10 inserted between them, at its periphery, which is not affected by the colour change.  The coating 10a on the filter paper may be a powdered mixture of ferrous ammonium sulphate and potassium ferricyanide, or ferric alum and potassium ferrocyanide.  A small amount of citric or tartaric acid may be included, if necessary, to develop the colour.  The assembly may be fitted to a hypodermic graduated syringe, and a measured quantity of the liquid drawn through the filter paper.  Alternatively untreated filter paper or a cotton wool plug may be used in conjunction with a capsule containing the salts placed upstream thereto.  The inorganic salts may be replaced by dyestuffs, e.g. crystal violet, auramine, rhodamine or magenta.

Title: Improvements in or relating to off-shore platforms
IPC: E02B17/02
Filed: 1959-03-16
Abstract: 843,339. Artificial islands. BATAAFSCHE PETROLEUM MAATSCHAPPIJ N. V., DE. March 16, 1959 [March 18, 1958], No. 8987/59. Class 68(2) An off-shore platform for use in situations where the bottom sail is soft is characterized in that the base is formed as a plurality of cells open at the top and bottom. The weight of the structure and load is supported by the skin friction between the vertical surfaces of the cells and the soil. The optimum ratio of the depth of a cell D (Fig. 3) and the length of a side wall L is established as D = .84 L and the ratio of the vertical wall area S to the horizontal area A enclosed by the base as S = 5.7 A. When the latter ratio is less than 5.7 an increased load forces the base further into the ground, but when the ratio is greater than 5.7 the soil enclosed by the base cells tends to move downwardly with the base.
