Abstract: A lamp capsule may be formed with substantially parallelepipedial ends including alignments. A metal strap may surround one end, between the alignments, with first and second oppositely disposed affixation areas of extensions. A glass stem has tubular first portion with outside diameter D. A C-shaped clip is mounted upon the tubular first portion. The clip has height H and inside diameter D1 smaller than the outside diameter D. The clip frictionally engages the tubular first portion. A first frame member has a proximal terminus affixed to the clop and a second frame member has a proximal terminus affixed to the clip opposite the first frame member. The first frame member has a distal terminus affixed to the one affixation area and second frame member has a distal terminus affixed to the other affixation area. The first and second frame members and the metal strap provide the support for the capsule.

Abstract: A mount assembly for a lamp has a glass stem (122) having a first portion (124) that is tubular and has an outside diameter D2 and a second portion (118) formed as a pinch seal. A blow-hole (125) is formed in the tubular first portion and is connected to an exhaust tubulation (126). A substantially C-shaped clip (100) is mounted upon the first portion (124). The C-shaped clip (10) has an inside diameter D that is smaller than the outside diameter D2 whereby the clip (100) frictionally engages the first portion (24). A pair of substantially oppositely located cutouts (102, 104) is formed in the clip (10), each providing an extending flap (106, 108) projecting away from the clip (100). This assembly accurately supports the structure and prevents rotation of the mount assembly. An upstanding tab (110) is located substantially midway between the extending flaps, i.e., opposite the open part of the clip, and angled inwardly toward the center of the C-shaped clip (100).

Abstract: An electric lamp (e.g., tungsten halogen) including an elongated envelope with at least one sealed end portion of flattened configuration. Located on the sealed end portion is a conductive base member of hollow configuration which is electrically coupled to the lamp's lead-in conductor (which projects externally from the envelope) and which is located not only substantially about the sealed end portion so as to substantially surround the end but also extends over a part of the envelope's body portion to thereby substantially prevent breakage of the sealed end portion (e.g., during lamp insertion and/or removal).

Abstract: Presented is a cathode-heater assembly including a support structure for the cathode-heater assembly that is particularly rugged in that it resists displacement of the cathode-heater assembly in all planes, and minimizes power requirements to raise the cathode to operating temperature.

Abstract: A microwave magnetron assembly in which the anode cathode and magnetic flux providing structures can be electrically insulated each from one or both of the others, and from ground potential; a housing surrounds and is spaced from the entire assembly, and a rigid insulating material fills the space between the housing and the assembly. The housing can be made of a material having magnetic shielding properties.

Abstract: A grid electrode for an electron tube with planar electrodes consists of a planar array of fine wires mounted on a support frame. The support frame has a circular outside rim and interconnected interior elements dividing the area inside the rim into three or more separated apertures. The interior elements include radial elements connected to non-radial elements, forming a mechanically rigid structure with good heat conduction to the outside rim which resists buckling out of its plane when differentially heated.
