Antistatic equipment

Claim 2

In apparatus for generating and dispersing ions, a. an electrical insulative carrier, b. a cluster of parallel needles having adjacent shanks and forming multiple relatively closely spaced metallic tips extending in the same direction, said needles carried by said carrier, and c. means electrically connected with said needles for supplying high voltage to said tips, said means including solder extending in the interstices formed by and between said shanks, and a metallic base supporting said solder and said shanks at the ends thereof opposite said tips.

Claim 3

In apparatus for generating and dispersing ions, a. an electrically insulative carrier, b. integral means forming multiple relatively closely spaced metallic tips extending in generally the same direction, said means carried by said carrier and comprising a cluster of needle shanks which extend in adjacent parallel relation, and a rigid bond holding said shanks in said adjacent parallel relation, said bond comprising solder having capillary positioning in spaces formed between said shanks, and there being a metallic base supporting said solder and said shanks at the ends thereof opposite said tips, and c. means electrically connected with said integral means for supplying high voltage to said tips, d. said insulative carrier including a molded plastic insert defining an axis and carrying said base at said axis, and a molded plastic hollow body receiving said insert.

Claim 4

In apparatus for generating and dispersing ions, a. an electrically insulative carrier, b. integral means forming multiple relatively closely spaced metallic tips extending in generally the same direction, said means carried by said carrier and comprising a cluster of needle shanks which extend in adjacent parallel relation, and a rigid bond holding said shanks in said adjacent parallel relation, said bond comprising solder having capillary positioning in spaces formed between said shanks, and there being a metallic base supporting said solder and said shanks at the ends thereof opposite said tips, and c. means electrically connected with said integral means for supplying high voltage to said tips, d. said insulative carrier including a molded plastic insert defining an axis and carrying said base at said axis, and a molded plastic hollow body receiving said insert.

Claim 5

The apparatus of claim 2 including a wire received within said body and electrically connected with said metallic base, there being plastic sheathing on said wire, and there being means on said sheathing blocking pull-out displacement of the sheathing and wire from said body.

Claim 6

The apparatus of claim 1 wherein said carrier includes a cylindrical portion extending about and receiving said tips, said portion forming an outlet to pass ions dispersed by said tips, there being a molded plastic grid on said portion and extending in alignment with said outlet.

Claim 7

In apparatus for generating and dispersing ions, a. an electrically insulative carrier, b. integral means forming multiple relatively closely spaced metallic tips extending in generally the same direction, said means carried by said carrier and c. means electrically connected with said integral means for supplying high voltage to said tips, d. said carrier including a cylindrical portion extending about and receiving said tips, said portion forming an outlet to pass ions dispersed by said tips, there being a molded plastic sheet forming a receptacle receiving said cylindrical portion of the carrier to mount the carrier.

Claim 8

In apparatus for generating and dispersing ions, a. an electrically insulative carrier, b. integral means forming multiple relatively closely spaced metallic tips extending in generally the same direction, said means carried by said carrier and c. means electrically connected with said integral means for supplying high voltage to said tips, d. said carrier including a cylindrical portion extending about and receiving said tips, said portion forming an outlet to pass ions dispersed by said tips, there being a molded plastic sheet forming a receptacle receiving said cylindrical portion of the carrier to mount the carrier.

Claim 9

The apparatus of claim 5 including structure supporting said sheet near the periphery thereof.

Claim 10

The apparatus of claim 1 wherein said means to supply high voltage to the tips comprises power circuitry, a container for said circuitry, and foamed plastic substantially filling the container and covering said circuitry.
