Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
An electron tube socket comprising a body portion and a cover portion, spaced pin receiving contact terminal and lead means mounted within said body portion to receive terminal pins of an electron tube; an electrical conductor ring positioned in said socket to be in spaced relation with said pin-receiving contact terminal and lead means; means on said ring for forming an arc gap with a respective pin-receiving contact terminal and lead means, whereby arc gaps having close tolerances relative to the specific voltage to be dissipated thereby may be formed between said ring and an associated pin-receiving contact terminal and lead means to prevent arching between the pin-receiving contact terminal and lead means; opening means formed in said cover portion to vent the interior of said socket to thereby permit any gases generated within said socket to pass outwardly, and to reduce pressure buildup within the socket, said body portion having extending flanges and said cover portion having channels for respectively receiving said extending flanges, and said opening means comprising an extension of one of said channels.
Claim 2
Dependent Claim
177 words
An electron tube socket comprising a body portion and a cover portion, spaced pin receiving contact terminal and lead means mounted within said body portion to receive terminal pins of an electron tube; an electrical conductor ring positioned in said socket to be in spaced relation with said pin-receiving contact terminal and lead means; means on said ring for forming an arc gap with a respective pin-receiving contact terminal and lead means, whereby arc gaps having close tolerances relative to the specific voltage to be dissipated thereby may be formed between said ring and an associated pin-receiving contact terminal and lead means to prevent arching between the pin-receiving contact terminal and lead means; opening means formed in said cover portion to vent the interior of said socket to thereby permit any gases generated within said socket to pass outwardly, and to reduce pressure buildup within the socket, said body portion having extending flanges and said cover portion having channels for respectively receiving said extending flanges, and said opening means comprising an extension of one of said channels.
Claim 3
Dependent Claim
26 words
A socket as in claim 1 wherein one of said extending flanges is foreshortened to enable a portion of the channel to comprise said opening means.
Claim 4
Dependent Claim
20 words
A socket as in claim 1 wherein said opening means is formed adjacent a terminal lead means subject to arcing.
Claim 5
Dependent Claim
20 words
A socket as in claim 1 wherein said opening means is positioned to vent away from the associated electron tube.
Claim 6
Dependent Claim
212 words
An electron tube socket comprising a body portion and a cover portion, spaced pin-receiving contact terminal and lead means mounted within said body portion to receive terminal pins of an electron tube; a high voltage arc chamber within said body portion enclosing the high voltage focus terminal lead; an electrical conductor ring positioned in said socket to be in spaced relation with said pin-receiving terminal and lead means; means on said ring for forming an arc gap with a respective pin-receiving contact terminal and lead means, whereby arc gaps having close tolerances relative to the specific voltage to be dissipated thereby may be formed between said ring and an associated pin-receiving contact terminal and lead means to prevent arcing between adjacent pin-receiving terminal lead means; opening means formed in said cover portion in the area surrounding said high voltage arc chamber to vent the interior of said high voltage arc chamber to thereby permit any gases generated within said high voltage arc chamber to pass outwardly, and to reduce pressure buildup within the socket, said body portion having extending flanges and said cover portion having channels for respectively receiving said extending flanges, and said opening means comprising an extension of one of said channels in the area surrounding high voltage arc chamber.
Claim 7
Dependent Claim
212 words
An electron tube socket comprising a body portion and a cover portion, spaced pin-receiving contact terminal and lead means mounted within said body portion to receive terminal pins of an electron tube; a high voltage arc chamber within said body portion enclosing the high voltage focus terminal lead; an electrical conductor ring positioned in said socket to be in spaced relation with said pin-receiving terminal and lead means; means on said ring for forming an arc gap with a respective pin-receiving contact terminal and lead means, whereby arc gaps having close tolerances relative to the specific voltage to be dissipated thereby may be formed between said ring and an associated pin-receiving contact terminal and lead means to prevent arcing between adjacent pin-receiving terminal lead means; opening means formed in said cover portion in the area surrounding said high voltage arc chamber to vent the interior of said high voltage arc chamber to thereby permit any gases generated within said high voltage arc chamber to pass outwardly, and to reduce pressure buildup within the socket, said body portion having extending flanges and said cover portion having channels for respectively receiving said extending flanges, and said opening means comprising an extension of one of said channels in the area surrounding high voltage arc chamber.
