Abstract
Abstract The invention concerns ion generation and dispensing apparatus having module form with an electrically conductive bus to which groups of ion generating radiants or clusters are connected, the modules being constructed for connection in series; the provision of means to dispense vapor in air flow created by the flow of such ions; means to use such ions to effect particle collection on surfaces; and means to control such ion polarity in relation to external conditions.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
167 words
In ion generation and dispensing apparatus for altering the static charge of work, the combination comprising: a. elongated insulative support members each forming recesses opening sidewardly, the exposed exterior of each said member being electrically nonconductive, b. an electrically conductive bus extending lengthwise in each said member and exposed at the end thereof, c. multiple electrically conductive inserts carried in said recesses to have threaded connection to said bus, and multiple electrically conductive ion generators carried by said inserts in said recesses to project toward the recess mouths and terminating at tips proximate the recess mouths so that electrical charge flowing to said tips will leave said tips and generate ions flowing away from said member and d. said members connected in end-to-end interfitting relation so that said buses therein have end-to-end mechanical and electrical connection with one end of the iNterfitting bus defining a tongue and the other end of the interfitting bus defining a groove, thereby to define an elongated system of generators and buses.
Claim 2
