Title: Method and device for detecting the temperature of melts
IPC: G01K11/06
Filed: 1968-05-13
Abstract: 1,220,832. Temperature indicators. CONTINENTAL ELEKTROINDUSTRIE A.G. [trading as CONTINENTAL ELEKTROINDUSTRIE A.G. ASKANIA-WERKE] May 13, 1968 [May 12, 1967; Sept. 20, 1967], No. 22669/68. Heading G1D. A device for indicating whether the temperature of an iron melt during refining is at or above a predetermined temperature comprises a body 3, e.g. of iron containing an explosive charge 8 to be ignited by a filament 7, and a tube 11 containing metal granules 18 which melt at the predetermined temperature thus shorting two electrodes 16, 17 disposed in the tube and normally spaced by a separator 14, the electric circuit to the filament 7 from a battery 5 being completed through the iron melt to ignite the charge 8 and provide an acoustic signal which may be detected by a microphone, if the temperature of the melt is above the predetermined temperature. If desired the tube 11 may contain two compartments containing granules having different melting points and having electrodes coupled to separate explosive charges to indicate whether one or both of the melting point temperatures have been exceeded, the action of the melt on the granules with the higher of the two melting points being delayed by the provision of a ceramic insulator round part of the tube 11. In alternative embodiments electrical ignition of the explosive charge is dispensed with and the heat of the melt is used to detonate the charge. In these cases the charge is disposed in a recess in a body of iron, the opening of which is closed by a disc of metal of predetermined melting point, so that when the disc melts the charge will ignite. Discs of silver plated copper foil may be disposed behind the metal disc to prevent radiated heat causing premature explosion of the charge. As before two recesses closed by discs of different melting temperatures may be provided to indicate the attainment of more than one temperature. Explosive mixtures which develop certain optical colour effects may be used to enable observation to be carried out optically rather than acoustically.

Title: Improvements in or relating to the production of caustic soda
IPC: C25B15/08
Filed: 1952-09-17
Abstract: In the electrolytic production of caustic soda by electrolysis of aqueous sodium chloride containing sodium sulphate impurity, in which the cell liquor is evaporated to crystalline <PICT:0721981/III/1> <PICT:0721981/III/2> sodium chloride and sulphate, the mixed crystals are washed with a grine solution whilst in the form of a bed on a perforate surface subjected to a centrifugal force of at least 200 times gravity, whereby the sodium sulphate is removed and the remaining sodium chloride ion can be recycled.  In the diagram (Figs. 1A, 1B), cell liquor is passed by line to evaporator 10 at 130 DEG F. where it is concentrated at 200 DEG F and 5"Hg vacuum to result in an up to 30 per cent sodium hydroxide solution.  Sodium chloride and sulphate are precipitated and the slurry flows to settler 13 where the caustic soda is withdrawn at 15.  The settled salt at 160 DEG F. passes by lines 21, 22 to a centrifugal 23, whilst a portion is recycled to settler 13 by pipe 24.  The salts on the centrifuge are first spun to remove caustic soda which is led off by pipe 25, and then washed with concentrated brine from line 31 optionally containing a surface active agent, conveniently 0.1 per cent. caustic soda, the salts on the centrifuge being subjected to a centrifugal force of at least 200g. during the brine wash which may be of 15 seconds or less duration.  The brine, containing the sodium sulphate then passes to a chill tank 27 where the sodium sulphate is precipitated and removed.  The sodium chloride in 23 is preferably washed next with water at 20 DEG F. after which the salt is spun dry and recycled to the cells by line 28.  The caustic soda from lines 15 and 25 passes to a further evaporator 17 and is concentrated to 50 per cent NaOH whereby further quantities of chloride and sulphate are precipitated and transferred as slurry by pump 33 to settler 35 (Fig. 1B).  The caustic soda is withdrawn at 36 and the salts fed to centrifuge 42 where they are first spun to remove caustic soda which passes by pipes 45, 47 to tank 37, and then washed with water at 200 DEG F.  The liquid passes to brine tank 52 where it is joined by brine from tank 27 (Fig. 1A) through line 54.  The total brine, supplemented with fresh brine from 57 is passed by lines 55, 56 back to centrifuge 23.  The caustic soda in tank 37 is chilled to 70 DEG F. when further salt is precipitated and the slurry passed to centrifuge 62 designed to separate liquid purified caustic soda of 50 per cent strength through line 63, from solid salt leaving through 64 to pass back to the salt settler 13.  In a modified arrangement, multiple effect evaporators may be used, to which the cell liquor is fed, and from which a concentrated caustic soda liquor is fed to a chill tank to separate the salts therefrom.  In such a system the liquor from the first stage evaporator is fed to a salt settler, the salts separated and centrifuged as before, and the caustic soda solution recycled to the second stage evaporator.

Filed: 1948-09-06
Abstract: 655,005. Automatic speed control systems. NITKA, H. Sept. 6, 1948, No. 23435. [Class 38 (iv)] [Also in Group XXXVIII] In apparatus for measuring and/or controlling the rate of travel of photographic films in a processing machine, a rotary machine member a (Fig. 1), is connected to a sprocket b which drives an endless highly magnetizable ribbon c at a speed similar to that of the film. The ribbon passes over a loose sprocket f and tension rollers e, and has previously been recorded with a signal of e.g. 5000 c.p.s. when moving at a steady speed of e.g. 20 inches per second, so that a magnetic pick-up g develops a signal of e.g. 250 c.p.s. when the film is moving at the required speed, e.g. 1 inch per second. The signal is applied to an amplifier h tuned to e.g. 250 c.p.s. to operate a pen recorder i, which is displaced by the fall in output voltage when the speed deviates from the desired value. In a modification (Fig. 2, not shown), the amplifier is detuned slightly from the frequency corresponding to the desired speed so that the output voltage increases or decreases in accordance with the magnitude and sense of the speed deviations to operate means for controlling the speed of the motor driving the film, and to displace the recorder in either direction in correspondence with the speed changes. A dial indicating instrument may also be used. Specification 14043/46, as open to inspection under Sect. 91, is referred to.

Title: A scanning circuit

IPC: H04Q3/54
Filed: 1966-05-26
Abstract: 1,141,903. Magnetic storage arrangements; automatic exchange systems. WESTERN ELECTRIC CO. Inc. 26 May, 1966 [15 June, 1965], No. 23535/66. Headings H3B and H4K. A calling line identification arrangement comprises first and second shift registers SR1, SR2, Fig. 1, of the movable domain wall type, with each subscriber's line L1, L2 ... connected to a different scan position in the first register SR1, those lines which are in the offhook condition establishing a reversed domain pattern which is propagated periodically by multiphase advance clock driver 33 through both registers in turn. A domain reversed by off hook current appears at lines 22 and 24 in turn during a shift cycle, its time position denoting the scan position and thus the line identity. No domains are propagated when all lines are on-hook. In operation, a line newly off-hook is identified by a pulse in line 22 alone when the domain reaches the end of shift register SR1 during the shift cycle immediately following, while continuance of the off-hook condition during subsequent cycles is denoted by the simultaneous appearance of pulses in lines 22 and 24. When a subscriber's line goes on-hook the new condition is denoted in the shift cycle immediately following by a pulse on line 24 alone. The newly off-hook or on-hook conditions of a line are identified by a circuit comprising exclusive OR gate 20 and AND gates 21, 23, 27, 28, each condition causing a central processor 12 to appropriately control a switching matrix 11. Each register may comprise a respective wire of ferromagnetic material having a rectangular hysteresis characteristic, or may comprise a single wire of such material with an intermediate sense coil connected to line 22. The magnetic wire 100, Fig. 2, is is coupled at spaced positions by coils connected to respective lines 1, 2 ... and is also coupled at these spaced positions by a common coil 101 connected to a nucleation driver 14, Fig. 1. When a line is in the off-hook condition, e.g. line 2, the line current is insufficient by itself to establish a reversed domain, but such a domain is established when a periodic pulse is received from the nucleation driver. A bias may additionally be used. In a modification, Fig. 5, each line La-Ld is coupled to a separate magnetic wire 100a-100d, each of a different length, so that pulses are induced in a common sense winding S, in turn, when the reversed domains established by off-hook lines are advanced by a multiphase advance clock driver 133 to the end of the register. In this arrangement the nucleation driver establishes a reversed domain in each magnetic wire by applying a periodic pulse to coil N, and domains associated with off-hook lines La-Ld are expanded by the offhook currents. Only expanded domains are propagated by the multiphase advance pulses applied to coils P2, P1 from advance clock driver 133, the stationary domains at the onhook positions being erased by a reset pulse in coil R from a reset driver 215.
