Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A spark gap pulse generator comprising: a pair of spaced, conductive, circular structures which are opposite and coaxial with one another, a raised boss positioned at the center of each of said circular structures and on the surface which is opposite the surface of the other circular structure to establish a spark gap space therebetween, each said circular structure having openings therethrough which are distributed thereover and which are aligned with the openings in the other circular structure, and a conductor extending in between said spaced circular structures and serially threading through all of the said openings therein.
Claim 2
Dependent Claim
98 words
A spark gap pulse generator comprising: a pair of spaced, conductive, circular structures which are opposite and coaxial with one another, a raised boss positioned at the center of each of said circular structures and on the surface which is opposite the surface of the other circular structure to establish a spark gap space therebetween, each said circular structure having openings therethrough which are distributed thereover and which are aligned with the openings in the other circular structure, and a conductor extending in between said spaced circular structures and serially threading through all of the said openings therein.
Claim 3
Dependent Claim
45 words
A spark gap pulse generator as recited in claim 1 wherein each of said spaced conductive circular, structure constitutes a disc, and a conductive hollow tube extends away from each openings in said discs, said conductor passing through the center of all of said tubes.
Claim 4
Dependent Claim
52 words
A spark gap pulse generator as recited in claim 1 wherein each of said spaced conductive circular structures constitutes a drum, said openings constitute elongated slots in the periphery of each said drum, said conductor has a cross sectional area such that the surface substantially parallels the surface of said elongated slots.
Claim 5
Dependent Claim
97 words
A spark pulse generator comprising: a pair of spaced parallel conductive discs, each disc having a raised boss mounted at the center thereof on the surface opposite the other disc whereby a spark gap is established in the space between the two bosses, a plurality of aligned openings disposed over the surfaces of said discs, a hollow tube extending from each opening and right angles thereto, and a conductor extending into the space between said disc, threading through all of the tubes on both of said discs, and then extending outwardly from the space between said discs.
Claim 6
Dependent Claim
97 words
A spark pulse generator comprising: a pair of spaced parallel conductive discs, each disc having a raised boss mounted at the center thereof on the surface opposite the other disc whereby a spark gap is established in the space between the two bosses, a plurality of aligned openings disposed over the surfaces of said discs, a hollow tube extending from each opening and right angles thereto, and a conductor extending into the space between said disc, threading through all of the tubes on both of said discs, and then extending outwardly from the space between said discs.
Claim 7
Dependent Claim
49 words
A spark gap pulse generator as recited in claim 4 wherein there is included: a source of operating potential, means for applying potential from said source to said discs, a load, and means for connecting the ends of said conductor extending from between said two discs to said load.
Claim 8
Dependent Claim
116 words
A spark gap generator comprising: a first and a second conductive drum spaced from one another and aligned with one another, each drum having a raised boss at the center of the surface which is opposite the surface of the other drum whereby a spark gap is defined by the space between said two bosses, each drum having radial notches in its periphery which are aligned with the radial notches of the other drum, and a conductor which extends from one end thereat into the space between said two spaced drums and extends through all of the notches of said two drums, finally extending to its other end out through the space between said two drums.
Claim 9
Dependent Claim
116 words
A spark gap generator comprising: a first and a second conductive drum spaced from one another and aligned with one another, each drum having a raised boss at the center of the surface which is opposite the surface of the other drum whereby a spark gap is defined by the space between said two bosses, each drum having radial notches in its periphery which are aligned with the radial notches of the other drum, and a conductor which extends from one end thereat into the space between said two spaced drums and extends through all of the notches of said two drums, finally extending to its other end out through the space between said two drums.
Claim 10
Dependent Claim
30 words
A spark gap generator as recited in claim 6 wherein said conductor has a surface area which substantially parallels the surface area of each notch in said circular drum periphery.
Claim 11
Dependent Claim
42 words
A spark gap pulse generator as recited in claim 7 wherein there is included a load which is connected to the two ends of said conductor, a source of operating potential, and means for applying potential from said source to said drums.
