Abstract: ABSTRACT OF THE DISCLOSURE         The present stress in the turbine rotor is estimated at each control period, from the steam tempera-ture and pressure at the turbine inlet.  In addition, the future turbine inlet steam temperature or pressure is preestimated once every nT control cycles, for a given speed or load changing rate, making use of data concerning the changing rate of the turbine steam inlet temperature or pressure in relation with the change of the speed or load, which has been obtained by a learning of the past turbine operating condition.  This future steam temperature or pressure at the turbine inlet is used as a factor for preestimating the future stress expected to be caused in the turbine rotor.  The preestimation of the rotor stress is performed for a plurality of assumed speed or load chang-ing rates.  The turbine is controlled at the maximum speed increase-rate or load changing rate which would not cause the future stress preestimated over a given preestimation time to exceed a limit stress.  An observation of the present stress is made at each control period to check whether the limit stress is not exceeded by the present stress.

Abstract: MECHANISM FOR ADJUSTING BLANKET-TO-BLANKET          SQUEEZE OF PERFECTING PRESS                 Abstract Of The Disclosure The squeeze of two opposed paper-receiving rolls of an offset printing press may be infinitely adjusted within a relatively small range by virtue of the fact that, each end plate supporting the rolls has a slit therein between the axes of rotation of the rolls which will permit slight deformation of the plate in a direction transversely of the slit upon manipulation of an adjusting mechanism to shift the rolls toward and away from each other.  Adjustment mechanism is provided on each plate and includes a cam that, when rotated by the longitudinal displacement of an operating link, has the effect of opening or closing a corresponding slit to thereby effect minute adjust-ment of the spatial relationship of the roll axes. The operating link has a specially threaded section from which the longitudinal displacement of the link is derived, the arrangement being such that the ratio of link rotation to link displace-ment is relatively high so that very fine adjust-ment of the critical roll relationship can be achieved.

Abstract: Abstract of the Disclosure The novel water-soluble disazo dyestuffs consist of two monoazo dyestuff moieties each containing as diazo component an amine of the benzene or napthtalene series and as coupling component an amino-naphthol-mono- or disulfonic acid.  The two moieties are bonded to each other via a triazine radical which carries a halogen atom, and is bound to the amino groups of the coupling components and the diazo components contain a fiber-reactive radical of the vinyl sulfone series.  To produce the dyestuffs 2 mols of the diazo compound carrying the fiber-reactive radical of the vinyl sulfone series is coupled with 1 mol of a bivalent coupling component consisting of 2 radicals of the aminonaphthol bound to the triazine ring via the amino groups, or two monoazo dyestuffs each synthesized from the aforesaid diazo component and an aminophthol-di-sulfonic acid coupling component are reacted with 1,3,5-tri-halogeno-triazine.  The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper. cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation.  The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural. regenerated and synthetic polyamides.  The are distinguished by clear shades, high tinctorial strength. a very good uptake from a long liquor and a good color-build up.  The dyeings obtained therewith have a high fastness to processing and in use.

Abstract: ABSTRACT        "Process for the production of steel from pig iron and scrap"         A bottom or side blown oxygen steel-making process with oxygen blown-in below the surface of the melt is additionally provided with oxygen top-blowing.  The top-blown oxygen is supplied through nozzles and the jets which issue from these nozzles are in the form of free jets which impinge on the surface of the melt. The free jets act with an injector effect to mix fully with the exhaust gases in the gas space of the converter in which the process is carried out. This provides efficient burning of the exhaust gases and effective transfer of the heat thus produced to the melt. The heat balance of the process is thus improved and thus allows a greater proportion of scrap to liquid pig iron to be used in the charge than can be used in conventional top or bottom-blown oxygen steelmaking processes.
