Abstract

Abstract A device is disclosed for use in neutralizing static electric charges and includes a bar provided with a lengthwise channel connected to a lengthwise parallel internal passageway by a slit through the intermediate wall with the bar being an extrusion of a material that is yieldably resilient. An insulated conductor has a plurality of discharge devices fixed thereon and is clamped in place with the conductor in the passage and the discharge points of the device extending through the slit into the channel with the walls of the slit in engagement with the discharge points. Grounded conductors are secured to the sides of the bar and they are interconnected through the bar by rivets which are located between discharge points.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 151 words
A device for neutralizing static charges, said device comprising a bar of material that is a non-conductor of electricity and has an open channel extending lengthwise thereof and an internal passage extending lengthwise of the bar parallel to but spaced from the bottom of the channel, the bar material between the bottom of the channel and the passage having a lengthwise slit effecting communication therebetween, a capacitor unit comprIsing an insulated conductor and a plurality of discharge devices including discharge points, said unit being within the bar, the conductor within the passage but exposed at one end thereof and the discharge points extending through said slit and into said channel, ground means extending lengthwise along at least one side of the bar, and means interconnecting the sides of said bar between certain ones of the discharge points and securing said ground means, the walls of the slit engaging the discharge points.
Claim 2
Independent Claim 151 words
A device for neutralizing static charges, said device comprising a bar of material that is a non-conductor of electricity and has an open channel extending lengthwise thereof and an internal passage extending lengthwise of the bar parallel to but spaced from the bottom of the channel, the bar material between the bottom of the channel and the passage having a lengthwise slit effecting communication therebetween, a capacitor unit comprIsing an insulated conductor and a plurality of discharge devices including discharge points, said unit being within the bar, the conductor within the passage but exposed at one end thereof and the discharge points extending through said slit and into said channel, ground means extending lengthwise along at least one side of the bar, and means interconnecting the sides of said bar between certain ones of the discharge points and securing said ground means, the walls of the slit engaging the discharge points.
Claim 3
Dependent Claim 24 words
The neutralizing device of claim 1 in which the diameter of the discharge points is substantially the same as the width of the slit.
Claim 4
Dependent Claim 20 words
The neutralizer of claim 1 in which the interconnecting means hold the walls of the slit against the discharge points.
Claim 5
Dependent Claim 42 words
The neutralizer of claim 1 in which the sides of the bar are resiliently flexible whereby they can be spread apart to enable the capacitor unit to be slid into position with the slit sufficiently wide to freely accommodate the discharge points.
Claim 6
Dependent Claim 38 words
The device of claim 1 in which each discharge device comprises a plurality of turns of a wire providing a sleeve-like portion dimensioned to receive the conductor within it with its ends extending vertically and comprising discharge points.
Claim 7
Dependent Claim 25 words
The device of claim 5 and an insulating spacer between each two devices, each spacer being a sleeve dimensioned to receive the conductor within it.
Claim 8
Dependent Claim 52 words
The device of claim 1 in which the channel, slit, and passage open through both ends of the bar, and a plug of material that is a non-conductor of electricity inserted in and secured to the other end of the passage and constituting a socket holds the corresponding end of the conductor.
