Title: Method and Apparatus for the Control of Electric Furnaces
IPC: C21C5/52
Filed: 1967-02-23
Abstract: 1,180,443. Control of electric furnaces. DEMAG-ELEKTROMETALLURGIE G.m.b.H. 23 Feb., 1967 [7 March, 1966], No. 8759/67. Heading H2H. A method of controlling an electric melting furnace comprises estimating or measuring the weight of the furnace charge, calculating the electrical energy required to effect a determined stage of a melting process, supplying a digital or analogue first signal representative of the calculated value to one part of a -comparator, feeding a second signal representative of the energy absorbed directly to another part of the comparator and obtaining a third signal which disconnects the furnace or initiates a further process stage when the first and second signals are equal. Where a changing operation is subdivided, the first signal is divided unequally so that the second part of the charge is added before the first part has fully melted. The furnace voltage may be set for each stage by hand or a punched tape system which is provided with a voltage indicator. Sensors may be provided for local temperature measurement and lining wear. A fourth signal may be added to the first for stages involving molten metal processes.

Title: Continuous polymerization of n-vinyl heterocyclic monomers
Inventor: VOEKS JOHN FORREST
IPC: C08F26/06
Filed: 1961-03-10
Abstract: In a continuous process for the polymerization in aqueous media of N-vinyl heterocyclic monomers, cross linking and gelation are inhibited by the use of one or more polymerization modifiers chosen from isopropanol, thioglycolic acid, dimethyl formamide, ethanolamine, methyl ethyl ketone, trichloracetic acid and 2-mercapto ethanol.  Heterocyclic monomers specified are N-vinyl lactam, N-vinyl caprolactam, N-vinyl-3-morpholinone, N-vinyl pyrrolidone, N-vinyl piperidone and N-vinyl-5-methyl pyrrolidone. These may be copolymerized with acrylic acid and its homologs, acrylic esters, methacrylonitrile, vinyl methyl ketone, vinyl chloride, styrene, or vinyl acetate.  The polymerization may be initiated by azo catalysts such as azobisisobutyronitrile, peroxygen catalysts, such as hydrogen peroxide and potassium persulphate, or by use of high energy radiation.  A polymerization vehicle may be prepared by mixing water with from 0,1 to 95% by weight of the polymerization modifier.  To this vehicle may be added 5 to 50% by weight of the N-vinyl heterocyclic monomer according to the amount of any copolymerizable ethylenic monomer present.  The polymerization mixture may be continuously passed through the reaction chamber, where it is mechanically stirred and maintained at a temperature of 25 DEG  to 100 DEG C.  The polymer may be recovered by spray drying or solvent stripping.  In the examples N-vinyl pyrrolidone is polymerized in aqueous medium in the presence of (1) isopropanol, aqueous ammonium hydroxide and aqueous hydrogen peroxide; (2) isopropanol and azobisisobutyronitrile and (3) thioglycolic acid and X-rays.
