Abstract: 1323074 Catalytic apparatus HUMPHREYS & GLASGOW Ltd 5 Aug 1970 [6 Aug 1969] 39405/69 Heading B1F [Also in Division C5] A tubular reactor comprises a furnace containing groups of vertically extending tubes for passing reactants through the furnace. Each group has an inlet header at one end and an outlet header at the other. There are main inlet headers, each connected to the inlet headers of groups, and the internal cross-sectional area of each main inlet header decreases downstream of at least one inlet-header connection by an amount substantially equal to the area of the connection, so that the flow-velocity along the main header is constant along its length, and the flow velocities at the several connections are substantially the same. Preferably the headers are arranged in pairs on a common axis, and flow is distributed evenly between the two headers on this axis by means of an elliptical sleeve within the main header, with its major axis equal to the diameter of the main header upstream of the connections, its minor axis along the common axis of the two headers, and its cross-sectional area equal to that of the main header downstream of the connections. The inlet main headers may be suspended as in Specification 1,320,148. The outlet headers may comprise T-pieces as disclosed in Specification 1,314,515. These outlet headers may lead to main headers, which may be of rectangular internal cross-section, and increase stepwise in cross-sectional area in a manner corresponding with the stepewise decrease of the cross-sectional area of the inlet main headers. The outlet headers are faired in to the outlet main headers to avoid turbulence. This reactor can be used for the manufacture of synthesis gas from light petroleum fractions and steam under high pressure.

Abstract: 1327572 Particle spectrometers ASSOCIATED ELECTRICAL INDUSTRIES Ltd 22 March 1972 [23 March 1971] 7594/71 Heading H1D In a charged particle analyser in which the charged particles from a source pass into the radial electrostatic field between a pair of coaxial tubular electrodes 1, 2, whereby particles of a given energy travelling in radial planes are brought to a focus, a collector aperture being positioned at the focus with a detector therebehind, the detector is so positioned that particles of the given energy cross the axis of the analyser at at least one position before reaching the detector, and a screen with an aperture (the # aperture) is placed in this position, whereby most of the particles pursuing skew paths, i.e. not travelling in radial planes, are prevented from reaching the detector. As shown in Fig. 2, the annular aperture 6 acts as a line source of electrons emitted from the source 3, whereafter they pass through a further aperture 7 (the α aperture), as shown formed in the inner electrode, which restricts the angle of divergence, and through a non-limiting aperture 8 to an annular focus 9 for receipt by detector 10, the skew electrons being largely removed by the #-aperture 12. In alternative arrangements, the electrons may be focused at a radius equal to that of the inner electrode, so that an annular aperture in the latter may be employed as the collector aperture (Fig. 3, not shown); or an annular electron source may be employed, the electrons passing through the #-aperture before entering the radial field, and eventually being brought to a focus on the axis (Fig. 4, not shown). In the arrangement of Fig. 5, the use of an annular detector is avoided by allowing the particles to pass through the field a second time. An electron or ion optical arrangement, which may have a magnification greater than unity, and can also be used to retard the particles, may be employed to focus the particles on to the α-aperture 7 of Fig. 2. The limiting apertures formed in the inner electrode may be replaced by apertures in separate plates, permitting ready charge of aperture dimensions, and the use of potentials differing from those of the inner electrode, to correct aberrations.
