Title: Channel induction furnaces
IPC: H05B6/06
Filed: 1976-03-22
Abstract: 1486073 Controlling temperature in channel induction furnaces ELECTRICITY COUNCIL 22 March 1976 [10 April 1975] 14802/75 Heading F4B [Also in Divisions G3 and H5] In a channel induction furnace, the introduction of gas into the molten metal charge (a technique known per se for various chemical and physical effects) has the incidental effect of changing the resistivity of the melt. The invention proposes to exploit this effect as a temperature control, making the rate of supply of a (preferably inert) gas to the melt dependent on the measured temperature thereof. Fig. 3 (not shown) depicts an otherwise conventional channel induction furnace with appropriate gas-supply arrangements; Fig. 2 (not shown) depicts the effect of varying the resistivity of the molten metal on the relationship between voltage and current in the heating circuit; and Fig. 1 (not shown) depicts the equivalent circuit diagram of the furnace (wherein the loop-shaped receptacle of molten metal acts as a resistor and inductor in series).

Abstract: 1,092,311. Creasing web material. KOPPERS CO. Inc. April 9, 1965 [April 10, 1965], No. 15319/65. Heading B6J. [Also in Divisions G1 and G3] As shown, Fig. 1, a system for controlling the position of a tool relative to the edge of a moving web comprises a sensor 30 which tracks the edge of a web 14 of corrugated board and controls the transverse position of a slitterscorer machine. Sensor 30 is mounted on a bar 31 attached to the main frames 15, 17 of the tool and is positioned by an hydraulic cylinder 35. The slitter-scorer comprises three pairs of shafts 19, carrying slitters and scorers, one pair of which operate on web 14 while the others are adjusted for the next production run. Shafts 19 are mounted on sub frames 11, 13 which are pivoted on shaft 20 and can be moved transversely to main frames 15, 17 by hydraulic cylinder 85. Sensor 30 comprises a depending finger 65 pivoted about an axis parallel to the edge of web 14 and carries a pair of cams 45, 47, Fig. 2, which operate one of a pair of switches 61, 62 as soon as finger 65 is displaced from the vertical position. Cam 47 also operates a third switch 63 when the deflection of finger 65 towards the web is large. Finger 65 is biased towards the web by a counterweight 67 attached to cam 45. The electrical and hydraulic circuits are described, Figs. 4 and 5 (not shown). In operation, the machine is set up by switching to a " safe " position in which sensor 30 is withdrawn from the edge of web 14 and the tool head sub-frames are positioned in the centre of their travel by hydraulic cylinder 88 which has a larger piston than cylinder 85 and therefore overrides it. The system is switched to the " run " position and sensor 30 is driven at high speed until finger 65 engages the edge of the web. This releases switch 63 and the sensor then moves at slow speed until finger 65 is vertical. The clamping action of cylinder 88 is now removed and as web 14 moves through the machine finger 65 responds to variations in the position of the edge and operates switch 61 or 62 as appropriate which operates valves to apply suitable hydraulic supplies to cylinders 35 and 85 in series to cause the sensor and tool head to follow the edge of the web. Switching is provided to enable the tool head to be positioned independently of the tracking system, and this facility may be used when the system is switched to " manual " control.

Abstract: 953,665. Measuring electrically. GAS DETECTOR S.p.A. April 28,1961 [March 2, 1961], No.15420/61. Heading G1N. To detect the presence in air of hydrogencontaining combustible gases such as vapours of alcohols, aldehydes, ketones, organic acids, or H 2 S, PH 31  the air is passed through a tube containing a heated resistance of, or coated with, an oxidation catalyst so as to cause any such gas to form water vapour which is then caused to humidify a solid hydrophilic substantially dry electrolyte in which are immersed a pair of electrodes which are connected to conductivity measuring apparatus. As shown, Fig. 1, the air under test is drawn by a pump P through a tube M1 containing a moistureabsorbing substance D such as CaCl 2 ; M is an alternative drying tube; each tube contains a heater H, H 1  for regenerating substance D. The dried air is filtered at F, then passed via a tube I to a combustion tube C containing a heated resistance RC coated with, an oxidation catalyst such a platinum black (alternatively the resistance may be made of a metal of the platinum group), and an electrolyte S, e.g. KCl, in which are embedded two electrodes E; the air is finally discharged through outlets U. Variations of conductivity of the electrolyte due to changes of humidity of the air impinging on it are used to actuate an indicator X and, through amplifying and/or relay means (which may be comprised within indicator X) if necessary, to operate an alarm such as a lamp N or a bell Z, or a suction fan, when the resistance of S is reduced below a predetermined limit. In Fig. 3, the dried, filtered air is passed to two tubes C, C1, the former containing a catalytic resistance RC and the latter containing a non-catalytic resistance R. The electrolyte S in each tube forms an arm of a Wheatstone bridge device, energized by A.C., with a rectifier W in the output circuit. In an alternative embodiment, the air is divided between two concentric tubes, the inner tube only containing a catalytic resistance, before being passed to two tubes containing electrolyte. The air may alternatively be dried by being passed through a liquid drying agent such as conc. H 2 SO 4 , or by being cooled. Instead of being dried, the air may wetted by being bubbled through water or an aqueous liquor.
