Filed: 1971-04-19
Abstract: 1293716 Electron microscopes SIEMENS AG 19 April 1971 [10 March 1970] 22775/71 Heading H1D In a scanning electron microscope wherein an output signal is derived from a detector in the vicinity of the specimen, the electric or magnetic field at the specimen is varied periodically and the output signal is fed either to a phasesensitive detector or to a band-pass filter tuned to the variation frequency, the output of which is mainly produced by secondary electrons emitted from the specimen. In the arrangement illustrated an oscillator O feeds a sine wave or square wave of 10 volts amplitude to the specimen P and also supplies a reference wave to the phase-sensitive detector PG. The input electrode F is connected to + 200 volts at B1, and the specimen P is provided with a D.C. bias of either polarity (e.g. - 5 volts) from a source B2 via a potentiometer P2 and change-over switch U. The direction of the electric field may be altered by changing the inclination α of the specimen. The secondary electrons e s  having low velocities are affected by the alternating field but the fast back-scattered electrons e, and the tertiary electrons e, produced by them are not, so the output fed to the display or recorder A is mainly proportional to the number of secondary electrons. In a modification an alternating magnetic field is produced by a coil disposed between the lens L and the specimen.

Abstract: 782,656. Steam superheaters. VICKERSARMSTRONGS (ENGINEERS), Ltd. March 4. 1955 [Aug. 10, 1954], No. 23244/54. Class 123(3) A steam superheater especially for use as the independently fired superheater in the installation described in Specification 782,655 [Group XXVI] consists of a number of tubes 12 bent to enclose a combustion space 18, the ends of the tubes being connected to a combined inlet and outlet header shown in detail in Fig. 1. The header consists of an outer header 2 within which is coaxially disposed an inner header 1. The annular space 3 between the headers is connected to the boiler, the in coming steam passing to tubes 12 through outlet openings (not shown) in header 2. The superheated steam is returned to the inner header whence it flows to the point of use. The connection of the outlet end of each tube 12, to the header 1 is made by means of a collar 9 to which the tube end is welded and a vertical tube 8 screwed into the collar and into a boss 6 in the inner header, the tube 8 passing through a clearance hole 5 in a boss 4 formed on the outer header 2 and being enclosed in a standpipe 10 respective ends of which are welded to the boss 4 and collar 9. The tubes 12, collars 9 and upper parts 10a of pipes 10 which are subjected both to high steam temperature and high mechanical stress are made of austenitic steel. Since header 2 is not exposed to high temperature and header 1 whilst so exposed is subject to very little mechanical stress due to pressure difference, both headers can be made of ferritic steel. To minimize heat flow therethrough, the inner header may be of the compound construction described in Specification 751,090 [Group XXVIII].
