Title: Regulation of vapour generators of the forced-flow, once-through type
IPC: F22B35/10
Filed: 1960-12-29
Abstract: 923,035. Fluid-pressure servomotor control systems. SULZER FRERES S.A. Dec. 29, 1960 [Dec. 31, 1959], No. 44645/60. Class 135. A method and apparatus for regulating the feed to a forced-flow once-through vapour generator 4 having a liquid separator 7 preceding a superheater 8 in dependence on the concentration of salts in the working fluid so that the feed increases with increase in the concentration. The feed from pump 1 to evaporator 4 is regulated by valve 2 actuated by proportionalintegral regulator 13 receiving signals from a flow meter 14 and restriction 3, and from a further proportional integral regulator 15 receiving a signal of the highest temperature from one of the evaporator tube temperaturesensors 5 and a signal at 20 which is one of a high or low desired value setting in lines 22, 23 from an output adjuster 24, the setting being proportional to steam generator load. The selected setting signal is determined by a switching device 21 which may be a potentiometer or an electro-hydraulic device as in Fig. 4, both controlled by a salt-concentration detector 25, 26. Detector 26 operates switch 72 which moves solenoid-operated valve 63 controlling piston 58 to slide lever 49 between piston 42, 43 receiving loads proportional to the setting signal whereby valve 51 is positioned with respect to a moving seat 52 on differential piston 53 which moves rod 20 giving a signal to regulator 15. Valve 16 regulating the flowdown of liquid from separator 7 is controlled by a level detector 17. When the salt concentration is below a predetermined limit, switch 21 brings in the higher of the desired settings so that a smaller feed occurs and a smaller quantity or none is blown down in the separator. Output adjuster 24 may be adjusted in response to the speed or inlet pressure of steam turbine 9 and may control fuel and air supply to the generator. Regulator 15 may receive a signal of the wetness of the steam. In another embodiment (Fig. 8, not shown), high salt concentration brings in a setting signal modified by a signal of the maximum of the evaporator tube temperatures while low concentration brings in a setting signal modified by the mean evaporator tube temperature, the signals then adjusting a variable output pump. In a further embodiment the invention is applied to a generator having an evaporator in two parts, the second of which may be by-passed through a valve controlled by salt concentration while a similarly controlled valve bypasses the separator. One setting signal is modified by separator flow while the other is modified by a signal of temperature between the separator and the superheater.

Abstract: 1,188,227. Selective printing. SIEMENS A.G. 26 Sept., 1968 [27 Sept., 1967], No. 45764/68. Heading B6F. Type case mechanism; type-carriers.-As continuously cycling type-carriers 1 travel around the semicircular track sections at each end of an endless track type case, an endless belt 5, lying upon the circumference of the toothed guide wheels 3 and (4, Fig. 1), retains the cylindrical pins 2 of the type-carriers in the sprockets of the guide wheels against the centrifugal forces produced. In the first embodiment (Figs. 1 to 5) one belt 5, and in the second embodiment (Figs. 6 to 9) two belts 5 pass round both guide wheels, and are directed by guide rollers (8 and 9) out of the straight track section remote from the printing hammers 6, to be tensioned by a movable roller (7, Fig. 1). Since the belts 5 are not necessary for guiding the type-carriers in the straight track sections in a third embodiment (Fig. 10) the belts 5 are diverted away after they have supported the type-carriers externally in the semicircular track sections. This is effected by deflecting rollers (40, 41, 42, or 40<SP>1</SP>, 41<SP>1</SP>, 42<SP>1</SP>) respectively. In the first embodiment, two cylindrical guide pins 2 (Fig. 3) have short, flattened extensions (2a) extending above each type-carrier, which extensions co-operate with grooves in the upper cover plate (11) of the type case, to guide the type-carriers in the straight track sections. In the second embodiment, slide rails (34, Fig. 9) engage in a recess in the type-carriers to guide them in the straight track sections. Also in the second embodiment, (Fig. 8), each guide wheel has a groove (e) in which the bodies of the type-carriers are guided in the semicircular track sections. The guide wheels are provided with flanged edges to prevent lateral shift of the guide belts 5. The guide pins 2, numbering one or more, and provided on the upper, lower or both sides of the typecarriers, may have anti-friction rollers mounted thereon. One toothed guide wheel is driven continuously. The other wheel is free running and is mounted so as to be capable of movement parallel to the two straight track sections, in order that the adjoining type-carriers can be adjusted to a minimum clearance.
