Abstract
Abstract A static electric neutralizer is disclosed in which a bar of a dielectric material has a lengthwise chamber open at least at one end and a series of bores in communication with the chamber. A sheathed conductor is confined in the chamber and discharge devices, one for each bore, are held capacitatively coupled to the sheathed conductor by plugs in the bores, the discharge points of the devices extending through the plugs. The open end of the chamber is closed by a terminal through which the contact section of the conductor extends. The bar, terminal, and plugs are of dielectric material and bonded together to prevent surface electrical leakage except along the discharge points.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
219 words
A static electric neutralizer comprising a bar having a lengthwise bore defining an elongated chamber opening through at least one of its ends and a series of bores spaced lengthwise thereof, each bore opening into said chamber, an insert in said chamber comprising a conductor including a main section and a contact section at one end, an insulating sheath for said main section, said sheath-carried means being circular in section and a sliding fit in said chamber-defining bore, a series of discharge devices, one for each bore and seated therein, each device including a discharge point and a contact portion, means carried by the sheath and overlying each bore and effecting, when engaged by the contact portion of a discharge point, the capacitative coupling thereof with said main conductor section, a plug for each bore through which the point of a discharge device extends and seating the contact portion thereof against said coupling means, at least one ground member extending lengthwise of said bar and secured thereto in spaced relation to said discharge points, and a terminal closing the open end of the passage with the contact section of the conductor extending therethrough, said bar, plug, and terminal being of dielectric material and so bonded together that the only surface paths of electrical leakage are along said discharge points.
Claim 2
Dependent Claim
219 words
A static electric neutralizer comprising a bar having a lengthwise bore defining an elongated chamber opening through at least one of its ends and a series of bores spaced lengthwise thereof, each bore opening into said chamber, an insert in said chamber comprising a conductor including a main section and a contact section at one end, an insulating sheath for said main section, said sheath-carried means being circular in section and a sliding fit in said chamber-defining bore, a series of discharge devices, one for each bore and seated therein, each device including a discharge point and a contact portion, means carried by the sheath and overlying each bore and effecting, when engaged by the contact portion of a discharge point, the capacitative coupling thereof with said main conductor section, a plug for each bore through which the point of a discharge device extends and seating the contact portion thereof against said coupling means, at least one ground member extending lengthwise of said bar and secured thereto in spaced relation to said discharge points, and a terminal closing the open end of the passage with the contact section of the conductor extending therethrough, said bar, plug, and terminal being of dielectric material and so bonded together that the only surface paths of electrical leakage are along said discharge points.
Claim 3
Dependent Claim
40 words
The static electric neutralizer of claim 1 in which the chamber is also open at its other end and en end plug closing the other end, the end plug also being of a dielectric material and bonded to the bar.
Claim 4
Dependent Claim
78 words
The static electric neutralizer of claim 2 in which the open ends of the chamber are sockets, one for the terminal and one for the end plug, the socket entering ends of the terminal and of the end plug having axial sockets into which the ends of the sheathed conductor extend, the ends of the conductor terminate short of the ends of the sheath, and a dielectric plug is seated in the sheath at the plug end thereof.
Claim 5
Dependent Claim
38 words
The static electric neutralizer of claim 3 in which the main and contact sections of the conductor are separate and a spring seated in the sheath at the terminal end thereof is held compressed between the conductor sections.
Claim 6
Dependent Claim
33 words
The static electric neutralizer of claim 1 in which the main and contact sections are separate and a spring is confined between the two sections and is held at least partly compressed thereby.
Claim 7
Dependent Claim
60 words
The static electric neutralizer of claim 5 in which the terminal has an axial socket in which an end of the sheathed conductor extends, the conductor terminates short of said end, the contact includes a head within the terminal socket, and a spring seated within said end is held at least partly compressed between the conductor and the contact head.
Claim 8
Dependent Claim
20 words
The static electric neutralizer of claim 1 in which each of the series of bores has a counterbored outer portion.
Claim 9
Dependent Claim
49 words
The static electric neutralizer of claim 1 in which the bar has a lengthwise channel extending along at least one of its sides and a ground member extends along that side and includes a portion locked in the channel and a portion in spaced relationship to the discharge points.
Claim 10
Dependent Claim
31 words
The static electric neutralizer of claim 1 in which a ground member extends lengthwise along one side thereof, and at least one supporting ground clip in engagement with the ground member.
Claim 11
Dependent Claim
21 words
The static electric neutralizer of claim 8 in which the bar has a pair of outwardly projecting ribs defining the channel.
Claim 12
Dependent Claim
25 words
The static electric neutralizer of claim 9 and at least one supporting ground clip secured to the bar and including a channel-entering and ground-member-engaging member.
Claim 13
Dependent Claim
53 words
The static electric neutralizer of claim 8 and at least one U-shaped supporting clamp, the free ends of the clamp being in the form of hooks shaped and dimensioned for entry into the channel and to be retained by the sidewall of the channel remote from the free ends of the discharge points.
Claim 14
Dependent Claim
64 words
The static electric neutralizer of claim 1 in which the bar has a lengthwise channel extending along its sides, a ground member extending along each side and including a portion within each channel, and at least one bar-supporting ground clip including end portions caught under the upper surface of each bar channel and in engagement with the channel entering portions of the ground members.
Claim 15
Dependent Claim
28 words
The static electric neutralizer of claim 13 in which the channel entering portions of the ground members are channels fitting the bar channels and interconnected through the bar.
Claim 16
Dependent Claim
24 words
The static electric neutralizer of claim 1 in which the bond between the bar, terminal, and plug is characteristic of sonic or solvent welding.
