Title: Improvements in or relating to electronic devices
IPC: H01J25/48
Filed: 1956-03-16
Abstract: 830,610. Space-charge wave tubes. RYDBECK, O. E. H. March 16, 1956 [March 18, 1955], No. 8301/56. Class 39(1). Signals are produced by the interaction of two electron beams within a space 1, Fig. 1, having the continuous character of a homogeneous wave-guide with no source of a transverse D.C. voltage within it. The first beam I is of narrow cross-section and travels longitudinally along the space while the second beam II has a large extent in the longitudinal direction. Beam I is modulated, e.g. in velocity, while beam II may be unmodulated or modulated in time, or in space. In Fig. 1 the beam from cathode 3 is velocity modulated in resonator 7, passes through rectangular space 1 and delivers up energy to resonator 11. The extended cathode 17 emits a wide unmodulated beam, controlled by grid 19, which enters space 1 through apertured wall 15 and interacts with the first beam to increase its modulation. The second beam may alternatively be modulated with another frequency giving frequency mixing or low frequency modulation of the initial high frequency. In another form the density of the second beam may vary cyclically in space along the longitudinal direction, e.g. by using a cathode of varying emission or a control grid 19 of variable pitch. For the amplification to be independent of the velocity of the second beam, the wavelength of the cyclic variation should be half the plasma wavelength in the first beam and the first minimum in density should be 1/8th the plasma wavelength from the beam entry. The variation need not be sinusoidal, and the second beam may simply be blanked off by screens at intervals. In a further modification separate beams IIA, IIB, IIC, IID, Fig. 4, may be emitted from separate cathodes 35 and grids 37 or separately controlled parts of a single cathode for modulation by different signals. The interaction space may be annular in cross-section with the beam passing through it radially inward or outward, Figs. 5, 6 (not shown). Lossy graphite material may be applied to the walls of the space. Feedback may be used.

Title: Improvements in or relating to arrangements for supplying heated air to furnaces
IPC: F23M20/00
Filed: 1921-03-22
Abstract: 184,828. Owen, W. H. March 22,1921. Regenerators; air supply, heating.-In systems for pre-heating air for furnaces to two different temperatures more particularly where the air delivered above the grate is heated to a higher temperature than the air delivered to the ashpit, the heat from the boiler and the smokeboxes is utilized to maintain or increase the temperature of the hotter part of the air on its way from the heater to the furnace. The arrangement as shown in Figs. 1 and 2 is applied to a marine boiler fitted with superheaters, the headers n being fixed in the smokeboxes. The uptake d containing the smoke-tubes f of the two-stage air heater e is offset from the boiler front to accommodate the air distributing passage k<1>, which is in communication with the fumaces through passanes k<2> and distributing ducts k<3>. The air to be heated is admitted through an opening i and passes through the upper portion of the heater e, when a part goes down the ducts j outside the wing smoke-boxes to the ash-pits, the remainder passing under the baffle g through the lower part of the heater. This further heated air is led through an opening k to the passages k<1>, k<2>, k<3>, where it receives heat from the boiler and smoke-boxes. Alternatively, the cooler and the hotter air may pass from the heater to the furnace through adjacent passages, separated by insulating walls. The arrangement is described as applied to a boiler without superheaters, the passage k being deeper and fitted with baffles to give the air a tortuous course, and so promote further heating.
