Title: Removal of unwanted organic acids from neutral organic material  as ammonium salts for oxidative disposal
IPC: C07C51/487
Filed: 1972-02-07
Abstract: 1374264 Removal of organic acids from organic material IMPERIAL CHEMICAL INDUSTRIES Ltd 7 Feb 1972 [18 March 1971] 7213/71 Heading C2C Unwanted organic acids are removed from organic material in a process which comprises treating said material with ammonia, separating the resultant ammonium salts therefrom and disposing of said salts oxidatively. The process may be carried out by washing the organic material with an aqueous solution of ammonia, evaporating the wash liquors to dryness and burning the residue. When the organic material is itself somewhat soluble in the aqueous phase it may, for washing purposes be dissolved in a solvent in which it has a greater solubility. The process is particularly described for manufacturing a mixture containing cyclohexanone and' cyclohexanol by partially oxidizing cyclohexane with a gas containing molecular oxygen, treating the product with ammonia, separating the resultant ammonium salts and disposing of the same oxidatively, e.g. by combustion.

Filed: 1936-08-19
Abstract: An electric resistance is composed as to a section or sections of its length of a mixture of heavy metal oxides united by sintering, the oxides when so united having a specific resistance exceeding that of the oxides taken separately.  By heavy oxides is meant oxides of metals having a specific gravity higher than that of aluminium.  The resistance of the oxides may have a negative temperature coefficient and be high at ordinary temperatures.  In a specific example, the main portion of the resistance comprises a mixture of 70 parts by weight of magnetite and 30 parts of chromium oxide, its specific resistance being about 29 cm.-ohms.

Patent GB-596639-A (GB)
Title: Improvements in or relating to distillation apparatus
Inventor: KLEINSCHMIDT ROBERT VICTOR
IPC: F28D7/02
Filed: 1944-04-28
Abstract: Distillation apparatus of the thermo-compression type characterised in that the heat-exchanger within the vaporisation chamber comprises several conical coils of piping nested together so that there are passages between the coils through which the solution to be distilled is introduced.  Figs. 4 and 5 show upper and lower portions respectively of an apparatus which can be easily dismantled for cleaning.  Solution to be distilled is fed through line 85 into vaporisation chamber 15 surmounted by compressor 19, the suction side of which communicates by means of aperture 23 with a liquid-vapour separator in the head of the vaporisation chamber, while the discharge side communicates by means of aperture 26, passages 41, annular passage 40 and headers 42 to 45, with the upper ends of conical coils 30 to 39.  The lower ends of the coils are connected by headers 55 to 64 with draw-off line 66.  Conical metal spacers 68 are disposed between the coils thus forming small tortuous passages between the exterior of the coil piping and the spacers.  Each coil is made up of six independent sections through which the compressed vapour flows in parallel.  The piping itself is threaded with <PICT:0596639/III/1> <PICT:0596639/III/2> square or other poly-sided wire to restrict the cross-section. Inside coil 30 is nested sheet 70, the upper end of which is cylindrical and forms part of the liquid-vapour separator.  The remainder of the latter is comprised by baffle 21, louvres 86, plate 71 and vent line 72.  Hot concentrated solution weirs over the top of wall 74 and passes down through annular space 76, passage 81, annular passage 79, and then out through line 82 which is connected with a "water leg" to keep passage 79 flooded.  Thermometer 106 in vent line 72 indicates whether the rate of supply of feed and the speed of the compressor are adjusted correctly.  Line 72 at this level is insulated from the coils and solution by the air space between it and wall 70.  A modification is described in which the direction of winding of the piping in the conical coils, instead of all being the same, is in opposite directions alternately.  In this modification the spacers may be dispensed with if desired.  A different method of headering and a different liquid-vapour separator is also described in connection with this modification.  The distillation of sea-water is referred to.  Specifications 512,657 and 536,371 are referred to.

Convention dates, June 26, 1946, June 27, 1946, and Sept. 5, 1946. [Class 96] Pulp is fed to a paper-making machine through a head-box 18, Fig. 1, having opposed sides 14, a bottom 13, a rear wall 15 and a front wall 16 carrying a slice 21 and rotatably mounted across the box is at least one perforated rectifying roll 30, 31, 32, which has axially-spaced discs 34, Fig. 3, fixed therein to aid in channelling the pulp through the roll so as to give an even flow of pulp across the box. Each roll may have open ends with scallops 46 and the outermost discs 34a may be spaced from the ends and may have axles 36 secured therein. The perforations 47 and 48 may diminish in size from the ends to the middle of each roll. The box, Fig. 1, may be divided into compartments 18a, 18b and 18c by buffers 27, 28 and 29, a rectifying roll being mounted under each baffle and the rolls may decrease in diameter towards the slice 21. The compartments may open into a head space in the box which may be covered by a top 17 fitted with a pipe 19 through which gas may be pumped into or out of the head space. Pulp may be admitted to a sump 24, may pass through the box in a straight path and may be discharged to a wire 11 through an outlet 22 between the slice 21 and an apron 20 attached to the bottom 13. The discs 34, Fig. 3, may be snugly seated in line with some of the holes 48 and may be welded to the roll at the edges 50 of the holes. All exposed metal surfaces of the roll may be dip-coated with a non-corrodible plastic, e.g. latex to round off sharp corners and rough surfaces. A shower pipe P may be fitted in the head space to prevent foaming.

Title: Improved means for displaying stair carpets
IPC: A47F7/16
Filed: 1926-03-24
Abstract: 273,000. Williamson, E. B., and Pollard & Go., Ltd., E. March 24, 1926. Non-endless chain and like carriers, apparatus with.-In carpet display apparatus in which a length of connected patterns is drawn in step formation over stair treads and under stair rods, means are provided whereby the strip g travels in substantially a straight line, and when stopped assumes the step formation. In one construction the treads h, i are hinged at their forward edges m, n and ride to the position shown at h<1>, i' when tension is applied to the strip by rotating one of the storage drums e, f. The treads h, i fall back on stops p by gravity when the drums are released, this action being assisted if necessary by weights t fixed beneath the treads. Alternatively the stair rods q are mounted on the risers j, k which are hinged at the top and move outwardly under the tension of the, carpet. The hinges may be located so that part only of the treads or of the risers move. Rollers u may be provided at the front and rear edges of the upper member l, at the front edges of the treads, and at the bottom of the riser y. A removable extension z may be inserted beneath the carpet to give with the member l the effect of a landing. The drums e, f are rotated by power or by hand, in the latter case by a handle v transferable either to the other drum or to a sprocket w connected to the drum by a chain. The carpet patterns may be detachably jointed together or mounted upon an under strip. The Provisional Specificaticn describes a construction in which the stair-way is built up on the lazy tongs principle so that the length of the carpet strip displayed is the same in the straight and in the step formations. The stair-way may be fixed at the top, bottom, or middle, and when extended the lower end may pass behind a concealing board. Stops limit the movement of the lazytongs, which are hidden from side view by fixed and movable screens. The actuation may be by a counter-weighted pedal. In a further construction the treads and risers are. linked to one another so that the whole can be drawn out from step to stretched-out formation.
