Abstract: A cathode eyelet has its cathode receiving end formed in an elliptical cross-section. Pressure on the long axis opens the short axis to a dimension large enough to admit the cathode. Removal of the pressure allows the sides of the ellipse defined by the short axis to collapse and frictionally retain the cathode in position until it is welded to the eyelet.

Abstract: An extractive electrode allowing to reduce the vertical focusing and defocusing effect of the hyperfrequency electrical field used for accelerating the particles of a beam within an accelerator of cyclotron type. The extractive electrode comprises a metallic block having a substantially prismatic shape and provided in its entry face facing the particle source with at least a window which opens onto a deep notch delimited by two curved lateral walls forming a channel C for the passage of the beam. A median element located within this channel C allows to obtain two separated channels for the passage of the two beams corresponding to two harmonic operating frequencies.

Abstract: An electrical surge arrestor having fail-safe properties and providing breakdown at a predetermined region within a sealed structure. The arrestor comprises a pair of axially symmetric electrically and thermally conductive electrodes having integral terminal portions and discharge portions. The discharge portions are disposed coaxially in spaced confronting or nesting relationship within a coaxial ceramic insulative housing to provide a discharge gap at a selected area to form a sealed enclosure. The discharge gap is configured so that the discharge portions of the electrodes will fuse in response to the presence of a predetermined overload condition. The operating lifetime of the surge arrestor may be lengthened by shading an annular inner surface portion of the insulating housing from the discharge gap in order to minimize the deposite thereon of conductive material discharged from the electrodes during breakdown. The electrodes and insulating housing are formed of materials having substantially similar thermal expansion coefficients for providing a metal to ceramic seal resistant to thermal shock.

Abstract: A gridded convergent flow electron gun employs a dimpled oxide coated thermionic cathode emitter facing a centrally apertured accelerating anode. A multiapertured control grid is interposed in the space between the dimpled oxide coated cathode and the anode for pulsing the electron beam. A multiapertured shadow grid is disposed overlaying the emitting surface of the cathode emitter with the apertures of the shadow grid being in alignment and in registration with the respective dimpled areas of the emitter and the corresponding apertures in the control grid for projecting a multiplicity of non-intercepting convergent flow beamlets through the individual holes in the control grid. The shadow grid is placed in nominal contact with the cathode emitter and is made of a material having essentially the same coefficient of thermal expansion as the cathode. In a preferred embodiment, the cathode includes a nickel base member and the shadow grid is made of nickel.

Abstract: This relates to means for effecting positive and sustained positioning of a heating element within an end-emissive cathode structure for utilization in a cathode ray tube electron gun. The orientation means is in the form of at least one heater positioning device located between a fixed heater support means and a connective extremity of the cathode heating element. The heater positioning device is formed of a bilaminate metallic material of predetermined flexure performance shaped to have an upper attachment portion at one end and a lower attachment portion at the opposite end thereof with acutely curved bend of bilaminate strip forming a partial loop of the material therebetween. Such bilaminate material comprises a first lamina of an active metallic alloy contiguously bonded along a common interface to a second lamina of a passive alloy material. The active alloy portion, upon being subjected to a predetermined temperature during tube processing, undergoes a metallurgical phase transformation effecting a volume change therein. The definite modification of the shaping of the positioning device thus effected exerts positive and sustained positioning of the heater element within the cathode structure in a manner to provide uniform spacing between the end of the heating element and the closure portion of the cathode.

Abstract: An electrically operated lamp that includes an elongate, transparent envelope having two tubular legs extending outwardly in the same direction from the ends thereof, the legs being substantially normal to the longitudinal axis of the envelope. At least one elongate refractory element that may be brought to incandescence by passage of an electric current therethrough is longitudinally disposed within the envelope and is at all times maintained in tension by two electric current-conducting springs at least partially housed within the legs. The lamp is particularly adapted for use with light block assemblies to produce an elongate zone of illumination of substantially uniform intensity through which multiple channel punched cards or punched tape pass. A light from this zone passes through openings in the cards or tape to actuate a lightsensitive receptor. The possibility of one or more channels of coding or decoding being lost due to individual lamp failures is eliminated, when a lamp of the present invention is used as a source for the zone of uniform light intensity. This zone extends transversely across the punched card or tape as the card or tape moves through a predetermined position.

Abstract: The planar tungsten-wire filament of a single-ended halogen type incandescent lamp is suspended at a predetermined location within the envelope by a unitary mount structure that is preassembled and has support wires that are coupled to the inner ends of the lead-in wires. The aforesaid coupling is achieved by providing helically coiled end portions on the tungsten support wires, slidingly fitting the coiled end portions over the tungsten inner end segments of the lead wires, and locking the members in predetermined telescoped relationship by hot-clamping the coiled portions to the leads, or by spot-welding molybdenum stud wires to the protruding inner ends of the lead wires. The axial adjustability afforded by the telescoped juncture permits standard mount assemblies to be used for lamp types which require different light-center-lengths. The numerous and unreliable tungsten-to-tungsten welds heretofore required are also eliminated.

Abstract: The invention comprises a process of manufacturing cold cathode gas discharge devices. A unitary metal electrode structure is inserted through a glass support, the metal and glass having the same coefficient of thermal expansion. The support and electrode structure are heated in the presence of oxygen to effect a seal therebetween. The gas discharge device is completed without removing the oxide coating formed on the electrode surfaces of the structure during the heating step. The resulting gas discharge device, which may be used for display purposes, has a stable oxide coating on electrodes thereof that attenuates display distorting reflections.
