Abstract: 1,143,201. Treating textile materials; warp printing. STALWART DYEING CO Ltd. 10 Feb., 1966 ]23 Feb., 1965; 4 March, 1965; 13 Aug., 1965], Nos. 7717/65; 9273/65 and 34680/65. Heading D1L. In a process for space-dyeing a yarp of yarns, with different colours over its length according to a predetermined pattern, the colours are printed on the yarns by means of pneumatically actuated dye-applicating means, the length and duration of successive actuations of at least one applicating means being controlled by a pair of series arranged switches operating according to predetermined cyclical switching sequences. In carrying out the process, the warp of yarns is drawn from a supply and passed through a reed and tensioning means to a dyeing station. In a preferred embodiment, the dyeing station comprises a plurality of troughs having applicator rollers partially immersed in dye liquor, and associated with each applicator roller, a pressing roller which is actuated by a piston and cylinder arrangement responsive to electro-magnetic valve means, the current supply to which is controlled by the aforementioned pairs of series arranged switches. The warp of yarns is withdrawn from the dyeing station and passed in substantially tensionless condition through a steaming chamber. Residual dye is washed from the warp which is then dried by passage through a chamber supplied with hot air flowing in countercurrent. The dye applicator rollers may be covered with foamed natural or synthetic rubber padding. A constant level of dye liquor is maintained in the troughs and the dye liquor is recirculated. The predetermined cyclical switching sequences are obtained by means of cam cylinders. Each pressing roller has associated therewith a pair of cam cylinders actuating a pair of microswitches. Preferably each cylinder has a circimferential series of spaced holes into which stub screws are selectively placed. The cam cylinders are arranged so that the one produces the colour pattern sequence and the other intersperses undyed portions along the pattern sequence by actuating its associated microswitch to prevent warp dyeing. If preferred, the warp may be dyed, with a ground colour, overall prior to selective colour dyeing as above to avoid lengths of white or undyed yarns in the finished product. Alternatively, while lengths may be subsequently dyed by applicator means controlled through a warpcontacting sensor device responsive to the absence of current-conducting dye liquor. The dyed warp may then be wound or supplied direct to a carpet tufting machine.

Title: Method of and apparatus for carrying out heat-consuming reactions
IPC: C01F7/445
Filed: 1959-03-09
Abstract: <FORM:0890226/III/1> Heat consuming reactions between finely-divided solids and gases are carried out by contacting the gases and solids in a fluidized bed, which is maintained in a reactor, the lower portion, 1, of which is narrower than the upper portion 2, which bed is continuous throughout the reactor and is expanded to such an extent that there is no well defined upper boundary.  Fluidizing gas is introduced into the reactor through a grate 3, and a gas at a temperature of at least 500 DEG C. is introduced laterally via 15 into the reactor where the wider portion begins, at such a rate that the gas velocity in the wider portion is at least as high as in the narrower portion, the laterally introduced gas providing at least 50% and preferably 80% of the total heat requirements of the reaction. The solids entrained by the exiting gases may be separated out by cyclones 4, 6, the solids from 4 being returned to the reactor via line 5, preferably below entrance 15 and above grate 3.  Preferably the recycled solids are at a sufficiently high temperature to provide at least 100% of the theoretical heat requirements of the reaction. Preferably the gas for reaction is introduced via grate 3 and heating gas only via 15.  The laterally introduced gas may be introduced at an angle from 30 degrees above to 30 degrees below the horizontal. In an example MgSO4-7H2O was converted to MgSO4 anhyd. by introducing flue gases at 500 DEG C. via grate 3 and oil combustion gases at 1200 DEG C. via line 8.  Similarly Al(OH)3 was converted to Al2O3.  In another example dry Al(OH)3, or Al2O3, was reacted with dry HF, introduced via grate 3 at 60 DEG C., to give AlF3, an inert gas, e.g. a flue gas, being introduced via line 8 at 600 DEG C.  In this example valve 12 was closed, and all the product was withdrawn via 10.  In another example sodium tripolyphosphate is produced from solutions of mono- and disodium phosphate, the solutions being p sprayed into a screw mixer inserted in line 5, such that the returned solids contain about 10% moisture.  Flue gas at 800 DEG C. enters via grate 3, and at 1200 DEG C. via line 8.  The water is evaporated and a dry granular tri-polyphosphate is obtained.  The calcination of lime, decomposition of iron sulphate, and production of metal halides, e.g. anhydrous aluminium chloride, are referred to. Specification 766,541 is referred to.

Title: Improvements in or relating to the manufacture of electric heating resistances
IPC: H01B1/04
Filed: 1928-03-17
Abstract: 287,458. Elektro-Heiz und Wõrme Ges., (Assignees of Heyrowsky, A.). March 19, 1927, [Convention date]. Resistance materials.-Electric heating resistances are constructed from carbon, such as graphite or gas coke combining only with difficulty with oxygen, which is ground, mixed with an oxide of silicon, calcium, aluminium, &c., made into a plastic mass with a binding-agent and pressed into filament form. The filaments are dried and heated, by the passage of an electric current, to a temperature exceeding by 100‹ the working temperature, the current being cut off when the desired resistance is attained. Variation of the resistance of the element is effected by varying the size of the carbon grains and the amount and nature of the oxides employed. A layer of metallic carbonate is stated to be formed on the surface of the filament during the heating operation. Finally, the filament is surrounded by a body of cast metal, such as bronze or aluminium, having a melting-point above the working temperature, a current being passed through the filament until the metal makes the solidification point. When the resistance is to be employed for high temperatures, oxides having high melting-points, such as those of zirconium, thorium or uranium, are used. In an example, 60 per cent of carbon, 20 of calcium and 10 each of aluminium and silicon oxides are employed, together with about 5 to 10 per cent of binding material such as tragacanth, mastic, venetian turpentine or coal tar &c.
