Abstract: A method for assembling a steam generator includes parallel assembly of the boiler framework and preassembly of assembly modules, and hoisting of the assembly modules into the boiler framework. The outer roof section of the boiler framework roof is then assembled. The inner roof section and the internal components are assembled simultaneously with assembly of the boiler wall in the upper section of the steam generator. The segments of the external support pipes are mounted into the assembly modules and subsequently connected at their module joints the external support pipes are mounted in the final position in the outer roof section. The buckstays and the header tie bars are mounted headers to the boiler wall or to the external support pipes. The auxiliary steel structure of the assembly modules the suspension equipment of the curtain walls are dismantled.

Abstract: The present invention relates to a chemical process for modifying inorganic and organic substrates with thin polymer films that are grafted to a substrate. The preferred composition includes a dimethylamino terminated precursor that is deposited as a self-assembled monolayer onto a gold or silicon oxide, or other substrate. The polymerization is then initiated by irradiation with UV light in the presence of monomer and an optional photosensitizer.

Abstract: A fixture and method is provided for in vitro storage of a cornea. The fixture includes a platform having a corneal-sceral rim receiving surface, a clamp having a mating surface for the cornel-scleral rim and handles. A locking mechanism is provided to secure a donor cornea between the clamp and platform. The combination cornea, platform and clamp are placed in a storage unit having a fluid preservation media. In one embodiment, the storage unit includes a vial having an optically clear closed end and an opened end. A lid is secured to the open end of the vial and engages the handles in order to stabilize the clamped cornea within the vial.

Abstract: A method for measuring fault locations in high frequency cables and lines. A signal with the frequency f0 and a level a0 is emitted from the source. This signal is split up in the splitter and is routed to the same parts in the test piece (DUT=device under test) and to a sink. The signals of the source and the returning wave of the DUT are added, whereby the result of this addition is a signal with the frequency f0 and an amplitude a1. The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded. An inverse Fourier transformation transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram can thereby be located.

Abstract: L-Menthol is prepared from D,L-menthyl derivatives by enantioselective enzymatic cleavage.

The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded, whereby this is repeatedly carried out in an appropriate frequency domain (Span). An inverse Fourier transformation is applied to the measured values and transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram, can, as a result, be found located while taking the shortening factor into account.

Abstract: Plain oval cigarettes which issue from a maker in such orientation that the minor axes of their oval cross-sectional outlines extend vertically are advanced lengthwise in the spiral groove of a trough toward an outlet where the major axes of their oval cross-sectional outlines extend vertically. The thus reoriented oval cigarettes are attracted to the undersides of receptacles which are pivotably mounted on a rotary carrier and deliver the cigarettes, without any further changes in the orientation of the major and minor axes of their cross-sectional outlines, to successive peripheral flutes of a rotary drum-shaped conveyor which transports the cigarettes in such a way that the minor axes of their oval cross-sectional outlines extend radially of the rotational axis of the drum-shaped conveyor. This ensures that the oval cigarettes are more reliably held in their flutes during advancement with the drum-shaped conveyor.
