Abstract
Abstract The base comprises a tubular housing adapted to fit over the exhaust tubulation of an electron tube stem, and a wafer flange extending outwardly from the open end thereof. The flange is apertured to receive an array of conductors of the stem. A recess is provided in the wafer flange facing the stem and a passageway communicating therewith is provided through the base separate from the housing cavity for the purpose of injecting a dielectric material into the recess around some of the stem conductors. The passageway may, e.g., be through the flange or in the housing wall. A shoulder is provided on the recessed face of the wafer flange to provide relief for random protuberances on the periphery of the stem to permit non-tilted mounting of the base on the stem.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
A base member adapted to be disposed over an array of lead conductors and an exhaust tubulation of an electron tube, said base member comprising: a. a tubular housing having an open end for receiving said exhaust tubulation therein, b. a flange extending outwardly from said housing at said open end thereof, c. an array of apertures through said flange for receiving said array of conductors therethrough, d. a recess in said flange encompassing said open end and at least one of said apertures, and e. a passageway in said base member separate from the tubulation receiving cavity of said housing and opening into said recess.
Claim 2
Dependent Claim
106 words
A base member adapted to be disposed over an array of lead conductors and an exhaust tubulation of an electron tube, said base member comprising: a. a tubular housing having an open end for receiving said exhaust tubulation therein, b. a flange extending outwardly from said housing at said open end thereof, c. an array of apertures through said flange for receiving said array of conductors therethrough, d. a recess in said flange encompassing said open end and at least one of said apertures, and e. a passageway in said base member separate from the tubulation receiving cavity of said housing and opening into said recess.
Claim 3
Dependent Claim
13 words
The base member of claim 1 wherein said passageway is through said flange.
Claim 4
Dependent Claim
17 words
The base member of claim 1 wherein said passageway is in the wall of said tubular housing.
Claim 5
Dependent Claim
23 words
The base member of claim 3 wherein said passageway extends longitudinally along said tubular housing wall from one end thereof to the other.
Claim 6
Dependent Claim
38 words
The base member of claim 4 wherein said passageway has a bend therein so that the opening of said passageway at the distal end of said tubular housing is offset toward the longitudinal axis of said tubular housing.
Claim 7
Dependent Claim
23 words
The base member of claim 4 further comprising a piston within said passageway for forcing material through said passageway and into said recess.
Claim 8
Dependent Claim
28 words
The base member of claim 3 wherein said wall of said housing is longitudinally grooved with the grooves being adapted to receive said conductors in the bottoms thereof.
Claim 9
Dependent Claim
39 words
The base member of claim 3 further comprising a tubular silo disposed alongside said tubular housing wall and closed at one end by said flange and open at the opposite end thereof for receiving one of said conductors therein.
Claim 10
Dependent Claim
45 words
The base member of claim 1 wherein said recess comprises two sections partially separated by a lip, whereby material injected from said passageway into one of said sections will substantially fill that section and then spill over said lip into the other of said sections.
