Title: Method and apparatus for controlling a steam generator
IPC: F22B35/10
Filed: 1972-04-10
Abstract: 1387716 Once-through boilers SIEMENS AG 10 April 1972 [14 April 1971] 16506/72 Heading F4A [Also in Division G3] In the control of a once through steam generator 1 (Fig. 1), e.g. to supply a turbogenerator, the specific enthalpy i 1  of slightly superheated steam is maintained at a desired value by adjustment of feed water throughflow rate and/or heating fuel supply in dependence upon a control signal Xw 1  significant of the deviation of the specific enthalpy from the desired value. The control signal Xwi is derived by a computer 21 (Figs. 1, 2), which computes the equation Xwi = Kp.Xwp + Kt.Xwt where Xwp is the deviation of actual pressure P1 in boiler 1 sensed by a sensor 19, from a desired value P 0 ; Xwt is the deviation in actual temperature Ti sensed by a sensor 17, from a desired value T 0 ; Kp + Kt are predetermined values which may be considered constants for small variations about a fixed working point A (desired condition P 0 T 0 ). If however, Xwi is to be determined for a relatively large working range, then KpKt cannot be considered as constants and may for example be varied as a function of load, such as the desired electric power output of a turbogenerator connected to the steam generator. In the Benson boiler 1 (Fig. 1), fuel is fed in at 2 for vaporizing feedwater in-flow 3, controlled by water valve 4. Some water is diverted at 6 to an injection cooler 13 via a valve 14. The feedwater through-flow rate is metered at 8, and the water passes through a preheater 10 and vaporizer 11. Steam leaving 11 is slightly superheated and the temperature and pressure are sensed by the sensors 17, 19 respectively. The steam passes to a superheater 12 and via the injection cooler 13 to superheater 15 and thence to a turbo-generator (not illustrated). Feedwater through flow rate is normally maintained constant by a feedback loop from the flow meter 8 to a comparator or summator 24 where it is compared with a desired value thereof. Any difference value is fed to a controller 25 of an actuator 5 which operates the valve 4. However, in the event of a breakdown in the heating, e.g. a momentary change in calorific value of fuel the resulting enthalpy deviation control signal Xwi fed to summator 24 causes the valve 4 to operate in a sense to maintain the specific enthalpy constant. Other computation circuits 21 are disclosed, with reference to Figs. 3 to 7, for specific operating conditions. For example, the desired specific enthalpy may be intentionally varied by superordinated controllers. Likewise, desired values P 0  and T 0  may be controlled in a load dependent manner, Fig. 8 (not shown), illustrates substantially a combination of Fig. 1, and the computation circuits of Fig. 7, and proportional integral control of the feedwater valve 4 is effected.

Title: Improvements in and relating to Method of and Apparatus for Heating by Electric Induction.
IPC: F27D11/06
Filed: 1917-11-14
Abstract: 111,844. Ajax Metal Co., (Assignees of Northrup, E. F.). Nov. 25, 1916, [Convention date]. Heating by electricity: induction furnaces.- Induction heating to high temperatures is effected by the use of currents of considerable frequencies as obtained for instance by condenser discharge. Frequencies of 12,400 and 25,600 have been found suitable. The frequency mav be varied by placing the condensers in parallel or across different sections of the inducing coil, or by non-inductive line construction. No iron core is employed in connexion with the inducing coil. A power factor approximating to unity can be attained. Fig. 1 shows the primary winding 0 of a furnace connected to supply conductors A, N through a condenser C' in one lead and inductances L<1>-L<4> in both leads. A spark-gap G shunts the conductors between the two pairs of inductances. A step-up transformer is added if the supply pressure is too low. If polyphase current is used, the phase circuits are inductively connected, so that the power consumed therein tends towards equality. For instance, inductances L<2>, L<2>, Fig. 3, in the secondary circuits of two-phase transformers may have a common core L<1>. A single inducing coil 0 may be common to the two oscillation circuits, which are bridged, as in Fig. 1, by spark-gaps G, G'. In a modified two-phase arrangement, the spark-gaps are in series with independent inducing coils wound together, and the condensers are in shunt to the coils and spark-gaps. A suitable double spark-gap has upper terminals G<5>, G<6>, Fig. 4, on an adjustable cross-bar, and lower terminals G<2>, G<3> with passages connected to air supply or exhaustion pipes, to prevent continuous conduction. In a furnace, the inducing coil 0, Fig. 8, may be a strip of nickel-plated copper, wound edgewise on the outer of two contiguous cylinders 31, 32 and spaced by asbestos cord 33. Insulated supply conductors 42, 43 pass through the base and casing as shown. The cylinders are let into a base 26 and are surrounded by sand within a casing 35. Around this is an earth-connected cage formed by upper and lower rings 50, 51 and vertical bars 52. A cover 14 fits partly within the casing and is positioned by a pin 39. The crucible 10 may be of conducting or non-conducting material; in the former case it carries most of the induced currents. It is designed to allow chilling of the metal charge. In the bottom of the crucible is a tapping hole, plugged by a carbon rod 13 secured by a pin 24 in a holder 23 which slides in a non- cylindrical hole in the cover under the action of a hand-wheel 16 and screw. An ingot mould may be heated, for the prevention of " piping," by an inducing coil around it near its upper end. Foundry ladles may be provided with coils for heating during " settling." Pasty materials, such as barium chloride, solid or hollow bodies, and substances normally liquid may be heated by the method described. The application to forging is mentioned.

Title: Method and apparatus for electrographic reproduction of originals

Filed: 1971-05-25
Abstract: 1350455 Facsimile system LA CELLOPHANE 25 May 1971 [25 May 1970] 16971/71 Heading H4F In a facsimile system an electrostatic charge image corresponding to an original is provided on a dielectric support by means of one or more metal styluses which may or may not touch the surface of the support, the resulting electrostatic image being then developed by means of pigmented particles (which carry a charge of opposite sign to that of the deposited charges and are coated by a thermoplastics bonding agent) and then fixed by heat. By deriving signals corresponding to the three primary colours of the original, a copy thereof may be obtained by forming the charge image on the support corresponding to one colour, developing it using particles pigmented in that colour and fixing the resulting image, and then repeating this process for the two other colours. In the embodiment described a collimated light beam C (e.g. a laser beam) is scanned by rotating mirror M over a moving document D and the reflected light is directed by mirror M and half-silvered mirror L to photo-cell P preferably via an afocal device not shown. A variable transmission filter f is preferably disposed adjacent the document D or a potentiometer is ganged to mirror M to compensate the video output from photo-cell P which varies as a function of the angle of scanning. The video signal is chopped H (a screened image is produced) and amplified A and fed to an electrode G, and the ring-connected thyristor switching elements T 1 -T n  are switched by chopper H so that the styluses sequentially form the correct charges on the dielectric medium B which is moved concomitantly with the document D. Direct, mirrored (reversed), positive, negative, enlarged and/or reduced images may be produced. Instead of using a line of styluses only one stylus need be used which is scanned over the dielectric support. The resulting charge image may be developed and fixed on the support or first transformed to another support. Colour reproduction is effected by repeating the image synthesis three times, the image analysis being effected using three photo-cells and respective colour filters, instead of photo-cells and optical scanning means, television pick-up tubes such as vidicons or orthicons may be used. The system may be replaced by a helical electrode on a rotating cylinder which co-operates with a fixed linear electrode, or by a plurality of rows of styluses which are sequentially energized row by row in synchronism with line by line scanning of the original. The scanning of the colour original may be effected simultaneously in three places for the three colours.
