IPC: C01D3/06
Filed: 1919-11-28
Abstract: 159,592. Reid, T. A. Nov. 28, 1919. Brine, concentrating; film evaporators.-In concentrating seawater, an open evaporating- pan is divided by partitions c into three compartments c<1>, c<2> c<3> used respectively for the final concentration, and the preliminary concentration, the preliminary heating. The pan is heated by a furnace or by the flue gases from the furnace of a boiler b, the compartment c<3> that receives the fresh brine being subjected to the greatest heat. The heated brine is passed to the compartment c', and is circulated through a framework or tower d, built above the pan and containing spaced wooden bars which allow circulation of air. The tower may be packed with wood wool, reeds, or coils of wire netting. A series of towers through which the brine is passed in succession may be built in the compartment c'. The concentrated brine is evaporated to crystallization in the central compartment c<2>, which may contain a concentrating tower. An open pan heated by steam from the boiler b may be used in addition to the compartment c<2> for the final evaporation. Seawater, concentrated by being used in the boiler b, may be passed into the compartment c'.

Abstract: 1,095,277. Coating apparatus. MONSANTO CHEMICALS Ltd. May 11, 1966 [July 14, 1965], No. 29828/65. Heading B2L. [Also in Division B5] Apparatus for coating patterns (Fig. 1) comprises a loading station (A), a slurry-coating station (B) and an unloading station (A), means to convey and rotate the pattern (7) between the slurry-coating and unloading stations for at least one complete revolution about each of two axes inclined to each other at at least 30‹, preferably at least 60‹, usually 90‹ and preferably simultaneously. There is preferably also a stucco-coating station (D) between the slurrycoating and unloading stations. The slurrycoating station may be a rservoir of slurry and the stucco-coating station may be a fluidized bed of stucco. The apparatus of Fig. 1 comprises a vertically-movable shaft (2), which is rotatable about its own axis to index 'radial' arms (4) sequentially at the various stations. The 'radial' arms (4) are also rotatable about their own axis and carry 'angled' arms (6) upon which the patterns (7) are mounted. The 'angled' arms (6) also rotate about their own axis. In operation, patterns (7) are loaded at A with arm (6) upwards and shafit (2) lowered. Shaft (2) is then raised and rotated, e.g. through 45‹, while rotating arms (4, 6). On lowering shaft (2), pattern (7) is lowered into slurry at B. Similar rotation of shafts (2, 4, 6) occurs to position C, which is a rest position, and then to position D, where the pattern is dipped into stucco, and then to A to 'be unloaded. Primary, secondary and tertiary gearboxes (1, 3, 5, see Figs. 3-5 not shown) comprise means to drive shafts (2, 4, 6), and are driven hydraulically or pneumatically. A hydraulically-operated clutch (14, Fig. 3, not shown) prevents rotation of the patterns unless shaft (2) is raised.

Title: Improved means for minimizing the sound caused by alternating currents in electronicvalves heated by alternating current
IPC: H04B15/00
Filed: 1924-12-18
Abstract: 226,555. Telefunken Ges. f³r Drahtlose Telegraphie. Dec. 18, 1923, [Convention date]. Thermionic amplifiers and generators.-In a thermionic amplifier or oscillation-generator in which the anode and filament are both fed from alternating-current sources of the same frequency, provision is made for permanently adjusting the relative phase-angle of both doublefrequency disturbances, so that they mutually oppose and counteract each other. The filament current is supplied from a source c, Fig. 1, through a transformer d, the filament being shunted by a resistance e to which the centre tapping from the oscillatory circuit b is taken in known manner in order to remove the singlefrequency disturbances. The plate supply is derived from a source g through a transformer h and full-wave rectifier i. The phase relation between the two generators g and c is first set in opposition by means of a coupling k, connecting the two rotors, and the amplitudes of the doublefrequency disturbances are then equalized by adjusting the value of the smoothing condenser g across the rectifier. As shown in Fig. 2, the necessary equalizing adjustments are secured by variably coupling the grid circuit to the anode supply through coils m, n. By shunting these coils with variable condensers p, p<1> and tuning the circuits so formed to the frequency of the disturbances an additional fine adjustment of phase angle is obtained. Or suitable impedance elements may be inserted for this purpose in the anode and grid circuits.

Title: Improvements in and relating to electric arc furnace control systems
Inventor: GUNTON FRANK DE LA ROCHE
IPC: H05B7/152
Filed: 1950-12-14
Abstract: 694,745. Automatic arc control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 9, 1951 [Dec. 14, 1950], No. 30531/50. Class 38 (iv). [Also in Groups XXXVII and XXXIX] In an electric arc furnace control system of the type in which a separately-excited reversible D.C. motor raises or lowers each electrode either automatically in accordance with arc voltage and current or in response to a manual control, the controlling signal is applied to a magnetic amplifier, the output of which is applied to the armature of the electric motor. A signal voltage proportional to electrode current is obtained across resistor 37 from a rectifier 34 and current transformer 33, a saturable transformer 48 being interposed to limit the signal voltage under fault conditions. A signal voltage proportional to arc voltage is tapped off a potentiometer 38, and the two signal voltages are applied in opposition to the control windings 27 of the magnetic amplifier. An adjustable resistor 44 is included in this circuit at starting to limit the speed at which the electrode approaches the charge to strike the arc, the resistor being short-circuited by a relay 36 when the arc strikes. The magnetic amplifier, Fig. 2 (not shown, see Group XXXIX), has a pair of metal rectifiers in series with a pair of saturable reactors connected in push-pull to the motor armature 13 so that the output voltage varies in magnitude and sign in accordance with the magnitude and sign of the input signal applied to the windings 27. Negative feed-back is applied to a further control winding 30 to vary the sensitivity of the system, part of a series resistor 31 being shunted by a metal rectifier so that the sensitivity can be varied as between raising and lowering the electrode to obtain the best furnace performance. As an alternative to automatic control, a voltage from an outside source may be applied to either half of the control winding 27 via contacts 51 or 54 of a manual controller 40, and the automatic signals may be disconnected by a switch 39. Specifications 628,104 and 640,633 are referred to.

Title: Improvements in and relating to electric regulating apparatus

Filed: 1926-12-06
Abstract: 262,474. British Thomson-Houston Co., Ltd., (Assignees of Thompson, L. W.). Dec. 5, 1925, [Convention date]. Regulation, automatic. - The voltage of an alternator 1 is regulated by a reversible motor 30, 31 operating a rheostat 5 in the field circuit 3. A bridge, comprising resistors 10, 11, 12 with zero temperature coefficients and a ballast resistor 13 with a positive coefficient is connected to the system 2 supplied by the alternator, and the mid points of the bridge are transformer coupled to the cathode-grid circuit of a valve 7. The anode circuit of the valve 7 includes a magnetic amplifier comprising a coil 22 surrounding a pair of cores 27, 28 on which are parallel connected coils 25, 26 forming a shunt circuit to the motor armature 30, which is supplied with AC. The coil 27, 28 are oppositely wound so as not to have a transformer action on the coil 22. At normal operation the cores 27, 28 are partly saturated so that the impedance of the coils 25, 26 is such that the motor 30, 31 does not develop sufficient torque to operate the rheostat. On increase of voltage, the anode current is increased, causing complete saturation of the cores 27, 28, whereupon the armature is virtually short-circuited and the motor runs as a repulsion motor to increase the resistance 5. On decrease of voltage, the anode current decreases, and the saturation is reduced so that the coils 25, 26 act as chokes, whereupon the motor runs in the opposite direction as an ordinary series wound commutator motor. In a modified system, the magnetic amplifier is included in one arm of another bridge, the other three arms being resistances, and the motor armature 30 is connected across the mid points of the bridge, the field 31 being supplied directly from the system 2.
