Abstract: A type of electrochemical cell has two electrode structure elements wound in a coil and inserted in a sealed can. The electrode structures are separated by a porous insulating sheet. One electrode structure has a metal substrate carrying a plurality of holes. The metal substrate supports layers of an electrode material such as porous carbon. Both edges and one end of the substrate is kept free of the material. The bare end of the substrate is on the outside of the coil. The substrate and porous insulating sheets are wider than the other electrode structures, so that when the coil is inserted in the can, the substrate and the porous insulating sheet makes contact with the top and bottom internal surfaces of the can.

Abstract: An antenna mount includes a mounting plate which holds an antenna such as a microwave horn. The mounting plate is connected by a hinge to a baseplate. The angle of the mounting plate with respect to the baseplate is controlled by an adjustable brace extending between the antenna mounting plate and a bracket, allowing adjustment of elevation. The baseplate is pivotally mounted on a mechanical ground allowing independent adjustment of azimuth.

Abstract: Trichlorotrifluoromethane is used as a vehicle to apply carbon and a binder to a substrate. Carbon black and tetrafluoroethylene are suspended in liquid trichlorotrifluoroethane to form a slurry. A layer of the slurry is deposited on a substrate. The trichlorofluoromethane is evaporated leaving a porous residue of carbon and tetrafluoroethylene on the substrate.

Abstract: A high pressure arc lamp has a ceramic arc tube envelope. A niobium feedthrough positions electrodes within the tube. A ceramic insert at each end of the tube forms a direct high temperature hermetic seal with the niobium feedthrough and the ceramic tube without the use of frits or brazing.

Abstract: An electric lamp has a candoluminescent filament. The filament has a resistive core which is heated electrically. Infrared radiation emitted by the resistive core is converted to visible light by a sheath of candoluminescent material surrounding the resistive core. The filament may be a sintered composition of carbon, ceric oxide and thorium dioxide. Carbon proximate to the surface of the filament is removed by oxidation, leaving a closed pore structure of candoluminescent material.

Abstract: Boron, oxygen, or a mixture thereof, is used as a sintering aid in sintering Mo-Ti alloys. Compounds formed between these sintering aids and the Mo or Ti have thermal expansion coefficients consistent with that of alloys of Mo and Ti. An hermetic member may be made using these constituents. The hermetic member may be used to seal an assembly such as a high pressure sodium lamp.

Abstract: A battery stack has a plurality of inner frames and a plurality of outer frames. Pairs of inner and outer rings are connected by a web of porous insulating material which separates battery plates. The frames are fused together forming a unity housing with an inner electrolyte well.

Abstract: An electroluminescent display is constructed as a laminate with a transparent front electrode and a metallic rear electrode sandwiching a layer of electroluminescent phosphor. A layer of light absorbing semiconducting material is interposed between the phosphor layer and the rear electrode. The semiconducting layer functions as a dark field increasing the contrast of the display. Furthermore, the semiconducting layer may be used in the fabrication of driver circuits integral to the display.

Abstract: A beam mode lamp has two discharge electrodes which alternately function as anode and cathode. One or more modifying electrodes are located between the discharge electrodes. Each modifying electrode is kept equal to or negative with respect to the cathode, raising the operating voltage of the lamp from a normal 20 volts to line voltage.

Abstract: The lamp shown herein is a beam mode fluorescent lamp for general lighting applications. The lamp comprises a light transmitting envelope, having a phosphor coating on its inner surface, enclosing a thermionic cathode for emitting electrons, a pair of anodes for accelerating the electrons and forming electron beams, and a fill material, such as mercury, which emits ultraviolet radiation upon excitation. The two anode configuration provides an extended region of electron beam excitation. In addition, a separate cathode heater filament is not required due to the anode configuration. As a result this lamp is operated with a single power source and only two conductors connecting the power source to the electrodes. This invention further provides a high degree of self-stabilization of discharge current by means of the twin parallel anode configuration.

Abstract: In one aspect of the invention, an electrochemical reserve cell is assembled by arranging within a cylindrical housing a concentric arrangement of a container, a lithium sheet, a porous separator, and a porous carbon element. The container holds a quantity of electrolyte solute which may be either a salt or dissolved in a solvent. A quantity of liquid cathode solvent is inserted in the housing but outside the centrally located container. Electrical contact is made between the lithium sheet and a cap terminal and the housing is sealed completing the assembly.To activate the cell, the container is broken, allowing its contents to mix with the solvent.

Abstract: The lamp shown herein is a beam mode fluorescent lamp for general lighting applications. The lamp comprises a light transmitting envelope, having a phosphor coating in its inner surface, the envelope encloses a thermionic cathode having a number of segments for emitting electrons, a plurality of anodes for accelerating the electrons and forming a corresponding number of electron beams simultaneously in two directions, and a fill material, such as mercury, which emits ultraviolet radiation upon excitation. The multi-electrode array configuration provides an extended region of electron beam excitation and thereby more visible light. A single power source and pair of connecting conductors provide both cathode heating current and electrode potential difference functions. In addition, this configuration provides for a greater and more complete discharge of the volume within the envelope than single electrode elements.

Abstract: Submicron silicon structures are fabricated by repeat oxidation and stripping the walls of a U-groove leaving thin silicon fingers.This method may be used to fabricate a silicon transistor having an emitter and a collector separated by a channel. The channel is formed in a silicon finger by a Schottky base, which at zero bias pinches off conduction of the channel. A bias voltage on the Schottky base causes conduction. The channel has a very short length making the transistor capable of high frequency operation.

Abstract: A gate-source structure and fabrication method for a surface-gate static induction transistor. The method requires only one masking step during fabrication, thereby eliminating or minimizing mask registration problems during fabrication of the devices. The method and the device are characterized by a two-step etching process which forms T-shaped gate windows in layers of poly-crystalline silicon with different doping levels. The source region is formed during an annealing step from the layer with high doping level. During the annealing step, the gate regions are also formed from gate impurities implanted previously in the gate windows. The source structure and the gate structure are separated by a silicon dioxide protective layer.

Abstract: A spiral line voltage pulse generator includes a double arm spiral structure about which is wound an elongated conductor. The double arm structure includes two conductive strips which are electrically insulated so as to hold a charge. Upon discharge, electromagnetic force is coupled to the elongated conductor which functions as a secondary winding increasing the voltage which would be generated by the double arm structure alone. The elongated conductor may, for example, be a continuation of one of the conductor strips or a wire solenoid.
