Abstract
Abstract An electron tube evacuating system includes a manifold section having an evacuation chamber. A tube mounting section has a plurality of evacuation apertures in communication with the evacuation chamber. A plurality of tube mounting members individually hermetically mount tubes to be evacuated onto the mounting section. Each mounting member has an aperture in communication with the evacuation chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A manifold system for simultaneously evacuating a plurality of electron tubes each having an exhaust tubulation comprising: At least one manifold section having an evacuation chamber extending the length of said manifold section; an electron tube mounting section extending along said manifold section, said mounting section having a plurality of evacuation apertures communicating with said evacuation chamber by means of a plurality of communicating apertures, said mounting section having protecting means circumscribing said communicating apertures to protect said exhaust tubulations from damage; a plurality of electron tube mounting members for individually hermetically mounting said electron tubes to said mounting section, said mounting members each having means to sealingly receive the tubulations of tubes to be evacuated and to communicate said tubulations through said communicating apertures with said evacuation chamber; and means for evacuating gases from said tubes and from said evacuation chamber, said means extending into said evacuation chamber.
Claim 2
Dependent Claim
149 words
A manifold system for simultaneously evacuating a plurality of electron tubes each having an exhaust tubulation comprising: At least one manifold section having an evacuation chamber extending the length of said manifold section; an electron tube mounting section extending along said manifold section, said mounting section having a plurality of evacuation apertures communicating with said evacuation chamber by means of a plurality of communicating apertures, said mounting section having protecting means circumscribing said communicating apertures to protect said exhaust tubulations from damage; a plurality of electron tube mounting members for individually hermetically mounting said electron tubes to said mounting section, said mounting members each having means to sealingly receive the tubulations of tubes to be evacuated and to communicate said tubulations through said communicating apertures with said evacuation chamber; and means for evacuating gases from said tubes and from said evacuation chamber, said means extending into said evacuation chamber.
Claim 3
Dependent Claim
29 words
The manifold system of claim 1 further including a cooling section extending along said manifold section, and also further including means for pumping cooling fluid through said cooling section.
Claim 4
Dependent Claim
58 words
The manifold system of claim 2 wherein said tube mounting members are threaded into said evacuation apertures, and wherein said means to sealingly receive the tubulations of tubes to be evacuated include resilient sealing members having apertures for receiving said tubulations, and means for compressing said resilient sealing members to hermetically seal said tubulations in said mounting members.
Claim 5
Dependent Claim
19 words
The manifold system of claim 3 wherein said manifold section and said mounting section are elongated and substantially parallel.
Claim 6
Dependent Claim
21 words
The manifold system of claim 4 wherein there are a plurality of said manifold sections arranged in a substantially parallel relationship.
Claim 7
Dependent Claim
23 words
The manifold system of claim 1 wherein said protecting means includes an O-ring disposed within an instep circumscribing each of said communicating apertures.
Claim 8
Dependent Claim
46 words
The manifold system of claim 1 wherein said means for evacuating gases from said tubes and from said evacuation chamber include tubing sections offset relative to said communicating apertures and extending above the bottom of the evacuation chamber to protect an evacuation pump from tube-source debris.
