Title: A method of burning minerals containing alkali metal compounds which are diffcult tovolatilize
IPC: F27D9/00
Filed: 1965-06-16
Abstract: Minerals containing alkali metal compounds which are difficult to volatilize, in particular raw powdered cement, are burned in a kiln by a method in which the kiln discharge is passed through a cooler through which air flows, the heated cooling air then at least partially being supplied to the kiln, and which also contains water which is evaporated therein in such quantities that the combined action of the steam thus produced and the heated cooling air when introduced into the kiln is sufficient to convert a substantial proportion of the difficultly-volatilizable alkali metal compounds into the hydroxides, which are then removed in the waste gases, so that a kiln discharge substantially free of alkali metal compounds is obtained.

Title: Method of inhibiting or reducing the formation of ice in liquid fuel and apparatus therefor
IPC: F02B47/02
Filed: 1948-09-30
Abstract: Liquid fuel contaminated with water is treated to inhibit the formation of ice therein at reduced temperatures by bringing it into contact with one or more aggregates of a solid substance, which is substantially insoluble in the fuel but soluble in water at ordinary atmospheric temperatures, under such conditions that a saturated aqueous solution of the solid substance is formed, this saturated solution being one which will not precipitate a substantial amount of solid or freeze when cooled to a temperature of -50 DEG C.  The liquid fuel is one for use in burners, internal combustion engines, internal combustion turbines or jet engines and may be of petroleum origin.  Suitable solids are chromium trioxide or mixtures thereof with anhydrous ferric chloride, anhydrous calcium chloride or anhydrous zinc chloride, but p  according to the Provisional Specification these anhydrous chlorides may be employed alone.  The aggregates may be disposed in a storage tank or, alternatively, the fuel may be caused to flow over the aggregates, for example on the way to the burner or engine.

Abstract: 708,461. Endless conveyer belts. CABLE BELT Ltd. Nov. 4, 1952 [Nov. 7 1951], No. 26100/51. Class 78 (1) [Also in Groups XXIV and XXV] In a conveyer belt comprising a plurality of belt sections each 'comprising rubber or like flexible material in which is embedded a layer of reinforcing material and each formed at each end with spaced longitudinal projections, the projections on one belt section end being adapted to fit between the projections on another belt section mating therewith, and transverse apertures being formed in all the projections so as to form, when the said projections are interfitted, a continuous transverse slat extending from side to side of the belt to receive a transverse member passing through the - apertures to connect the sections together, the ends of the reinforcing material are cut longitudinally to form fingers which are folded back upon themselves to form loops embedded in the rubber or like flexible material of 'the longitudinal projections and surrounding the transverse apertures therein,. As shown, each section is made by moulding rubber on a layer 12 of reinforcing material such as duck. Before the belt is moulded the ends of the layer 12 are cut to form alternately short and long fingers of equal width, the long fingers being folded back to form loops 18 and the shorter ones to form loops 20. Pieces of reinforcing material 22 are attached to the layer 12 to form additional transverse loops. The rubber is then moulded over the layer 12, the covering being of greater thickness on the underside of the belt at each point 23 where a piece of reinforcing material 22 is located and at each end 24. Transverse openings 25 surrounded by the loops of reinforcing material 22 are formed in the thickened portions 23, whilst the thickened portions 24 are divided to form projections 15 each having an aperture 26 surrounded by a loop 18, the apertures in the group of projections 15 at each end of a belt section being in alignment. Webs 27 are formed between the roots of the projections 15 on the upper side of the belt, and the ends of the projections 15 are recessed at 28. When the ends of two belt sections 10, 11 are brought together as in Fig. 1, the projections interchange and the webs '27 in one section fit into the recesses 28 in the other section, the apertures 26 in both groups of projections then being in alignment. A spring steel bar 29 is then passed through these apertures to hold the sections together. A bar 30 similar to the bar 29 is then passed through the opening 25, and heads (not shown) then mounted on these bars for engagement with cables on which the belt is to be supported, and by which the drive is transmitted.

Title: Protein complexes
Filed: 1955-09-15
Abstract: Proteinaceous materials in a highly purified or undenatured form are isolated by adding a completely or partially fluorinated aliphatic acid, amine, alcohol or alcohol derivative, having at least four carbon atoms, or a salt thereof, which provides in aqueous solution an anion or cation with a non-polar group, to a solution of at least one proteinaceous material to form a fluoro compound-protein complex, adjusting the pH of the solution to precipitate the complex and removing the fluoro compound from the separated complex, e.g. by dilution, dialysis, or ion-exchange procedure.  The pH of the solution is such that the fluoro compound and the protein carry like charges, the pH adjustment being to substantially the isoelectric point of the protein or a region where the fluoro compound and the protein carry unlike charges.  A plurality of proteins having different isoelectric points may be separated from a mixture thereof by repeatedly adjusting the pH of the solution to precipitate the individual protein-complexes and liberating the protein from each separated complex.  Proteins mentioned are ovalbumin, gelatin, human serum albumin, fibrinogen, bovine gamma globulin, beta-lactoglobulin viruses, antitoxins and enzymes such as urease.  Specified fluoro compounds are perfluorobutyric, caproic, caprylic, capric and lauric acids and the corresponding acids in which the omega fluorine atom is replaced by hydrogen, together with omega hydro perfluoro pelargonic, undecoic, tridecoic acids, and salts thereof; alpha dihydro perfluoro aliphatic alcohols and amines having from four to twelve carbon atoms and their salts, e.g. hydrochloride, hydrobromide, sulphate or phosphate.  The term "alcohol derivative" is defined as a partially fluorinated aliphatic alcohol of formula (i) ROSO3H, (ii) ROSO2X, and (iii) RSO3H and their salts, where X is a metal or ammonium and R is a fluoroalkyl radical containing at least four carbon atoms.

The invention relates to a microwave oscillator of the type comprising a valve 14 mounted coaxially within one end of and with its cathode ring 20 connected to a tubular outer cavity 12, the anode 16 being connected to a coaxial inner conductor. As shown the inner conductor comprises inner member 62, over which slides a tuning member 58 terminating in a choke 36, the position of which is adjustable by means of screw 42. A tubular member 66 is connected to the grid ring 18 being disposed coaxially between the outer cavity 12 and inner conductor 58 so as to produce grid-anode and gridcathode cavities, but being limited in length so that an anode-cathode cavity occurs beyond it.
