Abstract: An anode structure for a magnetron provides for low eddy currents and efficient water cooling. The anode structure may be made by machining a bimetal blank including an out layer of a first metal and an inner layer of a second metal and formed by explosion bonding. The second metal has a resistivity lower than first metal and a thermal conductivity higher than the first metal. The machining may result in the anode structure with vanes each having a center (tip) portion made of the second metal and the rest made of the first metal. The machined anode structure may be coated with the second metal.

Abstract: Electronic textiles and methods of fabrication electronic textiles. Nanoparticles of a conductive material are sprayed along a conductive path into a fabric material so as to penetrate into the fabric. A layer of a second conductor material is coated over the nanoparticles along the conductive path. A layer of an insulator material is coated over the layer of the second conductor material so as to encapsulate the conductive path and form a trace. An electrode configured to contact a subject wearing the fabric material includes a layer of a third conductor material coated over the layer of the second conductor and electrically coupled with the conductive path. An electrical connector is secured to the fabric material and electrically coupled with the conductive path. The nanoparticles are sprayed onto the fabric material using a dual regime spray process implemented with a dual regime spray system.

Abstract: Lighting devices are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The ratio of the weight of the conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers to the weight of the base resin host is between about 0.20 and 0.40. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or the like, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or the like, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like.

Abstract: An electrodeless lamp comprises an envelope containing a fill and a substance for facilitating the starting of the lamp. An outer tube is secured to an outside portion of the envelope in proximity to the given region and an inner tube is disposed within the outer tube such that a fluid passageway is defined between an inner surface of the outer tube and an outer surface of the inner tube. A hollow retractable electrode is provided within the inner tube, the electrode having a first position in which its tip portion is in proximity to the given region of the envelope when the lamp is being started and a second position in which the tip portion is away from the envelope after the lamp is started. A source of cooling fluid is operably connected to the hollow electrode such that the cooling fluid is forced through the hollow electrode and exhausted through the fluid passageway.

Abstract: In a controllable high-power electron tube in the form of a tetrode, the anode direct voltage is reduced to less than 10 kV with an anode efficiency of greater than 80%. The tube includes coaxially arranged electrodes including a cylindrical indirectly heated full walled matrix cathode containing BaO, a cylindrical control grid, a cylindrical screen grid and an anode, where the spacing between the control grid and the cathode and the spacing between the control grid and the screen grid is less than 1 mm. Such a tube can be used for achieving AM broadcast transmitters which are distinguished by a compact construction, the overall efficiency remaining largely unchanged.

Abstract: A method of modifying light and heat emission patterns from an electrodeless lamp which includes an envelope containing a plasma-forming medium and a source of electromagnetic energy coupled to the plasma-forming medium. The method consists of rotating the envelope at a rate fast enough to modify surface heating and the distribution of radiating plasma along lines of constant longitude on the envelope.

Abstract: An electrodeless low-pressure gas discharge lamp includes a glass lamp vessel (1) which is provided with a sealing member (6) connected to the wall of the lamp vessel by means of a suitable sealing material, and which has on its inner wall a conductive layer (7), at least part of which is transparent, that extends beyond the connection to the sealing member (6), the member being slightly recessed into the lamp vessel. The inner conductive layer can thus be connected in a simple manner to an electrical conductor, which during operation of the lamp is connected, for example, to one of the supply wires of the mains.
