Title: Improvements in or relating to the tapping of electric furnaces
IPC: F27D3/18
Filed: 1961-02-10
Abstract: 933,833. Tapping melting furnaces. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTRO-METALLURGIQUES. Feb. 10, 1961 [Feb. 11, 1960], No. 5099/61. Class 51 (2). [Also in Group XXXV] A method of tapping an electric furnace comprises controlling the movement of a tapping electrode in accordance with the current flowing through it, the electrode being moved towards the tap hole of the furnace when the current is below a preset reference value and being withdrawn from the tap hole when the current is above the reference value. As shown, an electric furnace 1 has a tap hole 4 and a tapping electrode 6 supported in a bearing 8 for longitudinal movement by a motor 20 and associated mechanism. To tap the furnace the electrode 6 is energized and is moved forward by the motor 20 under the control of a known regulator (not shown) until it makes contact with the crust at the tap hole whereupon an arc is formed. Thereafter the electrode moves back or advances automatically to keep the current about the reference value until all the crust is eaten away. The arc, still under automatic control, then remains in contact with the liquid content of the furnace and prevents it solidifying during tapping. The operating mechanism is provided with a crank wheel 27 for manual operation.

Title: Improvements in or relating to the preliminary treatment or purification of illuminating or coal gas or coke oven gases intended for the recovery of hydrogen by partial liquefaction
IPC: F25J3/08
Filed: 1923-02-26
Abstract: 195,598. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. March 30, 1922, [Convention date]. Separating gaseous mixtures by liquefaction.-In a preliminary purification of coal or coke-oven gases prior to partial liquefaction, the gases, after having been dried and freed from sulphur compounds, benzol and carbon-dioxide, are passed through a heat exchanger E which they enter by a pipe A, and travel in counter current to the hydrogen, nitrogen, carbon monoxide and methane previously separated from the gases; the hydrogen circulates from pipe B to pipe C and the remaining gases from pipe D to pipe X. As the gases descend they are cooled, but the more condensible constituents are prevented from solidifying by mixture with the liquefied and less easily condensible constituents. The liquid mixture so obtained comprising all the easily condensible gases and a little methane is drawn off through a cock R, and reheated by passage through a coil S. If the proportion of methane is high, liquids less rich in methane may be drawn off through a cook R<1> at a higher level. The apparatus may be modified to collect the condensates fractionally by arranging draw off cocks at suitable heights. A small quantity of alcohol may be added to the gases and the alcoholic liquid containing all the water in the gases removed by collectors in the upper part of the heat exchanger. Specifications 174,327 and 175,605 are referred to.

Title: Electrically heated apparatus for waving hair
IPC: A45D4/16
Filed: 1948-02-26
Abstract: 638,722. Electrically heated hair-waving apparatus. NESTLE-LE MUR CO. Feb. 26, 1948, No. 5793. Convention date, Feb. 7, 1947. [Class 39 (iii)] [Also in Group XXXVII] Hair waving apparatus of the type known as a " preheater machine " comprises heat storage curler heaters 38, heated by being detachably clamped on to electrically heated rods 32, at least one of which, by means of a thermally responsive bar 72, controls switching of the main heating current. The bar 72 which lies against the rod 32, is rigidly mounted at one end but is free to move lengthways at the other. A bell crank lever 86 having unequal arm lengths magnifies and transmits movement of the free end of the bar 72 thus operating the micro switch 70. When one thermostat only is used similar bars are fitted to the other rods 32 to keep the heat storage capacity of each rod substantially the same. The bars are narrow enough to permit the curler heaters 38 to clamp effectively on the heater rods, and plates 52, 54, 56 are curved to form closed chimneys which induce air flow past the finger pieces of the curler heaters thus minimizing ovet-heating. Green light 102 operates when the main contacts of the heating circuit'are open, indicating that the curler heaters 38 have attained proper temperature, and red light 104 operates when the heating circuit is completed, thus indicating that the machine is working, but that the rods 32 are not at proper temperature.
