Filed: 1977-05-27
Abstract: 1520210 Discharging metal melting furnaces V D MISCHENKO and A E MIKELSON 27 May 1977 [28 May 1976] 22459/77 Heading F4B In a metal melting furnace, a wall 9 extends from the hearth to a tap hole 11 in the direct heat from a heater 8 in the upper part of the furnace, and a travelling magnetic field inductor 10 is arranged below a non-magnetic plate 12 secured to the underside of the wall 9 so as to allow for thermal expansion. By altering the energization of the inductor 12, the arrangement may be used to stir the metal or discharge it. To prevent gas reaching the tap hole 11 and retain the temperature of the melt discharged, heat conducting wall 13 is arranged above the wall 9 to extend from the furbace wall and dip in the melt. The non- magnetic plate 12 may be made of titanium and the shield 13 may be made of corandum.

Title: Improvements in or relating to automatic temperature and speed control system for a continuous automatic machine for the production of relief pattern packing paper or similar material
IPC: B31F1/12
Filed: 1955-06-03
Abstract: 808,900. Automatic temperature control. S.A.F.F.A. SOC. P.A. FABRICHE FIAMMIFERI ED AFFINI. June 3, 1955 [July 12, 1954], No. 22684/57. Divided out of 808,899, ]Group VIII]. Class 38 (4). In a system for controlling the temperature of the rollers of a machine for the continuous production of relief pattern packing paper wherein the rollers are heated by electrical resistances, control is effected by three thermocouples fitted to the rollers, one controlling the temperature limit and the other two maintaining the temperature difference within predetermined limits. The heaters 2, Fig. 4, which are within the rollers 1 and are evenly spaced around the periphery are " star " connected to a three-phase supply through slip-rings on the shaft and the temperature of the rollers is detected by a thermocouple 39, the end of which is inserted into a groove between a pair of discs 3, 3<SP>1</SP>. The heater resistances 2, 2<SP>1</SP> are connected to the mains through the contacts 18, 18<SP>1</SP>, Fig. 1, of relays 16, 16<SP>1</SP> and both relays are released when the output of thermocouple 12 opens contact 15 of a contact voltmeter 11 in response to the rollers reaching the temperature determined by the setting of a trip arm 10. Thermocouples 20, 21 which are connected in series opposition control, by the sign and magnitude of their difference of output, the arm 22 of electromagnetic apparatus 23 to tilt a mercury switch 27 in the appropriate direction. Relay 16 or 16<SP>1</SP> is thus operated to interrupt the current supply to the hottest roller when the temperature difference exceeds the limit set by feelers 25, 26. The expansion of mercury in a bulb 30 which is coupled to roller 1<SP>1</SP> by a roller 31 is arranged to control the speed of the pattern rollers in proportion to their temperature through a piston 34 in a cylinder 33, and a cam 36 which regulates a governor through a lever 37. The speed control may alternatively be effected electrically or electronically.

The (soft magnetic) shield members almost touch the (ferrite) core at the lower (track) end but are spaced from it higher up to leave space for two windings wound around the side parts formed by a central hole in the core. High-frequency A.C. is applied to one winding, the signal induced in the other having an amplitude depending on the presence or absence of a tooth (ferromagnetic) of the movable member adjacent the lower end of the ferrite core. A plurality of such sensing devices (13) are provided each for a respective toothed disc (6) of a rotor. The rotor and encoder casing are magnetized by a coil (11) or permanent magnets.

Abstract: 1396604 Sintered oxides STICHTING REACTOR CENTRUM NEDERLAND 16 May 1972 [17 May 1971] 22990/72 Heading C1A [Also in Division G6] Spherical nuclear fuel particles are made by dispensing in a liquid medium an aqueous solution of an actinide compound, gelling the resulting droplets by the action of ammonia, and sintering the resulting globules at a heatup and cooling rate of 10-65‹ C./min. The aqueous solution may be an actinide hydroxide sol. or a solution of an actinide salt or aniondeficient salt. The actinides uranium, thorium, plutonium, amonium and curium are referred to. The solution may also contain carbon and/or a compound of Zn, Hf, Y or rare earth metal. The gelling may be effected by supplying free NH 3 , e.g. by mixing the actinide solution with ammonia solution before dispersal or by decomposition of an ammonia donor. Gelling may be assisted by heat and/or removal of H 2 O. Sintering may be batch or continuous. In a continuous process a dry, O 2 -free atmosphere (e.g. 25% H 2 , 75% N 2 ) is maintained during the whole process. In a batch process, the atmosphere may be moistened during heating and sintering. The sintering may be preceded by a calcination in an O 2 -containing atmosphere, e.g. by heating to 300-650‹ C. from room temperature at a rate of 200-300‹ C./hr., or sintering may be preceded by preheating in a reducing atmosphere or in vacuo. In examples, solgel globules of ammonium di-uranate are sintered at 1300-1650‹ C., using heat-up and cooling speeds of 10-30‹ C./min., with and without pre-calcination in air to 450‹ C.
