IPC: D06L4/50
Filed: 1931-05-12
Abstract: 377,768. Electrolytic treatment of fibrous material. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (Dierig Akt.-Ges., C. ; 45, C÷penickerstrasse, Zweigwerk, Gr³nauer Bleiche, Gr³nau, Berlin.) May 12, 1931, No. 14040. [Class 41.] Textile fibrous material is treated for removal of sizing, steeping and bleaching by passage of alternating current through a moving mass of the moistened material. The treatment may be applied to the material while immersed in liquid but is preferably applied outside the bath. In the apparatus shown. a fabric 1 is passed through a suitable liquid in a vessel A and is then passed between rollers 7a .. 7f, 8a .. 8f, appropriately connected to an alternating current generator 43. It then passed through a vessel C and between rollers 13f .. 13a, 14f .. 14a, and repeats the circuit several times, the layers being separated between the two vertical stages by rollers 10. The drive is effected by rollers 15. The fabric leaves the apparatus in a direction at right-angles to the plane of the section by passage over an inclined rod 21 and resumes its original direction by passage over a second inclined rod (not shown) to a tension-compensator G from which it passes to various treating baths. The contact rollers 7, 13 may be of aluminium ; the rollers 10 may be of metal coated with ebonite. A voltage of 220 at 50 cycles is suitable ; auxiliary treatment by high-frequency current may also be employed. Three-phase current may be employed ; special methods of connection of the contact rollers to the phases are described. The impregnating solutions are employed in higher concentrations than those of ordinary bleaching liquors ; to prevent destruction of the fibres anti-catalyzers are added such as colloidal magnesium silicate for bleaching liquors containing oxygen, caustic soda solution for liquors containing hypochlorite, and sulphuric acid for liquors containing sodium peroxide. Colloids such as waste lyes of the sulphite cellulose process and water glass may also be added to absorb pectines, protein substances, and colouring matters. The treatment is applicable to vegetable, animal, and artificial fibres in the form of loose fibre, yarn or fabrics.

Title: Automatic control system for optimizing performance of process units
IPC: B01D3/42
Filed: 1973-03-23
Abstract: 1420671 Automatic control EXXON RESEARCH & ENG CO 23 March 1973 [7 April 1972]  14076/73 Heading G3R  A process control system includes a plurality of feedback loops. Each of a number of parameters is monitored and a corresponding deviation from a reference value is determined. The value of an independent variable is then adjusted so as to reduce to zero the deviation corresponding to the parameter for which the smallest charge in the independent variable is required. As shown, a distillation column 10 receives an input on feed line 11 by way of a feed rate controller 21 and a furnace 17. The column produces sidestreams 13, 14, and overhead product on line 12 which includes a reflux condenser 18. It is required to maximise the input feedrate, and the controller 21 is adjusted in dependence on measured process variables such as heat input to furnace 17, pressure across the column 10, column reflux rate, and bottom product flow, each variable being associated with a limiting or required value. The actual and required values of each variable are compared and the differences are normalized by factors relating changes in the input feed rate to corresponding changes produced in the variables. The smallest normalized deviation is selected automatically, and the feedrate is adjusted so that the corresponding variable is brought to its pre-set value. This variable is  subsequently regulated by a closed loop system  until variations in the process or operator actions cause another variable to approach its limiting or desired value more closely, when that variable will determine the controlled feedrate.

Abstract: 943,371. Sintering machines. METALLGESELLSCHAFT A.G. April 13, 1962, No. 14450/62. Heading F4B. The pallets of a sintering machine, in which sintering and cooling is performed on the upper and lower strands respectively, each have two axles of unequal length. The shorter axle 8 (Fig. 2) carries wheels 10b and rollers 9b and the longer axle carries wheels 10a, rollers 9a and additional wheels 11. The sintering machine, which is shown in elevation in Fig. 1 and schematic plan in Fig. 3, has lowering wheels 12 spaced apart the distance between the wheels 11 and lifting wheels 16 spaced apart the distance between the rollers 9a (and 9b). Running rails 2 and return rails 4 are both spaced apart the distance between the wheels 10a (and 10b) and short curved rails 18, which are concentric with the lifting wheels 16, are spaced apart the distance between the wheels 11. In operation, a pallet passes over the wind boxes 3 along the rails 2 until engagement of the lowering wheels 12 with the wheels 11 causes the pallet to tip and empty the sinter into a shoot 14 from where it discharges into a previously emptied pallet. The pallet is then returned to the horizontal position by engagement of the wheels 10a, 10b, with the curved part 4a of the return rails 4. The pallet passes along the rails 4 over the cooling wind boxes 5 until the wheels 11 ride on to the curved rails 18. The pallet then tips to discharge the cooled sinter and is lifted and restored to the horizontal position by engagement of the lifting wheels 16 with the rollers 9a, 9b. The lifting wheels only are driven by a motor 19.
