Abstract: A cathode system includes an impregnated pellet and a conductive cup, which has substantially cylindrical sides. The conductive cup has an open end sized to receive the impregnated pellet and a closed end. The closed end has an internal surface and an external surface. The cathode system also includes a second conductive cup. The second conductive cup also has substantially cylindrical sides, an open end and a closed end. The cathode system further includes a similar third conductive cup. The three conductive cups are electrically coupled together. For construction of the cathode, the first conductive cup receives the impregnated pellet following coupling of the three conductive cups.

Abstract: A coupled cavity traveling tube employs a number of adjacent stacked annular magnetic coils (52a-52l) of insulated copper tape mounted on a housing (40) that contains an electron beam path (22) surrounded by a coupled cavity circuit (42,44). An electron beam that is focused by the annular magnetic coils is projected by an electron gun (10) at one end of the traveling wave tube to a collector (26) at the other end of the electron beam path. RF input and output ports (48,50) are coupled to opposite ends of the coupled cavity circuit, with the entire assembly mounted in an outermost device housing (12,28,36) that is sealed to and around the externally projecting RF input and output ports by a pair of sealing rings (60,62) that circumscribe coils (52b,52c,52l) at opposite ends of the traveling wave tube. Hot melt plastic (58a-58i) is injected into spaces between adjacent ones of the annular coils to firmly position the stack of coils against shock and vibration.

Abstract: An electrical interconnection assembly is disclosed for use with high voltage devices such as traveling-wave tubes. The assembly includes an electrically insulating housing having a plurality of recesses formed in its outer and inner surfaces. Leads from the high voltage device can be connected directly to respective conductive pins mounted in recesses in the housing inner surface, and electrical conductors from a power supply can be connected directly to respective conductive pins mounted in recesses in the outer surface of the housing and which are electrically connected to respective conductive pins on the inner surface. Protruding staggered gripping elements on the housing outer surface and on a removable cover plate for the housing minimize the possibility of separation of electrical conductors from the conductive pins.

Abstract: A high-power coaxial cable is disclosed comprising an inner conductor, an outer conductor coaxially disposed about and spaced from the inner conductor, and insulating fittings disposed between the inner and outer conductors near opposite ends of the cable to maintain a desired spacing between the inner and outer conductors. The insulating fitting at one end of the cable has a plurality of longitudinal holes therethrough to reduce the dielectric constant and the impedance of the fitting. The fitting is formed in two like sections joined at right angles to one another along a substantially 45.degree. interface, thereby defining a short 90.degree. turn for the inner conductor near the end of the cable. The fitting sections are retained in position by a surrounding mounting block, the opposite ends of which respectively receive a conductive sleeve and an end of the outer coaxial conductor in press-fit relationship.

Abstract: A method for processing various organic materials such as lignocellulosics or biomass into more useful states, such as charcoal, carbon black, and coke, and other processed products while producing useful off-gases, includes feeding aggregate pieces of the material to a vertically extending heating chamber and, preferably, closing the chamber to air to control oxygen therein. The pieces are conveyed upwardly through the chamber in a predetermined time by spiral vibratory conveyor. The chamber is heated to a preselected temperature sufficient for gaseous conversion of volatile hydrocarbon constituents of the material. Resultant off-gases are removed from the chamber for further use such as burning thereof for heating the chamber or condensing volatiles, etc.Apparatus for carrying out the method includes preferably first and second such chambers, there being continuous spiral vibrator tray in each chamber carried by a central, vertical support column.
