Apparatus for applying small particles to articles in an electric field

Claim 1

AN APPARATUS FOR APPLYING FLOCCULATED MATERIAL TO A MOVING WEB SURFACE COATED WITH AN ELECTRICALLY CONDUCTIVE ADHESIVE, WHICH COMPRISED A HIGH VOLTAGE ELECTRICAL SOURCE, AN ELECTRICALLY CONDUCTIVE MEMBER CONNECTED TO A FIRST OUTPUT TERMINAL OF SAID SOURCE AND DISPOSED FOR CONTACT WITH THE ADHESIVE COATING ON THE WEB TO ESTABLISH SAID COATING AT A GENERALLY UNIFORM ELECTRIC POTENTIAL CORRESPONDING TO TAHT OF SAID FIRST TERMINAL AND AT A HIGH VOLTAGE DIFFERENCE WITH RESPECT TO THE ELECTRIC POTENTIAL OF A SECOND OUTPUT TERMINAL OF SAID SOURCE, GUIDE MEANS DISPOSED FOR ENGAGEMENT WITH SAID WEB TO DIRECT THE MOVEMENT THEREOF LENGTHWISE ALONG A PREDETERMINED PATH PASSING THROUGH A FLOCCULATED MATERIAL COLLECTION ZONE, A CONVEYOR BAND OF LIMITED ELECTRICAL CONDUCTIVITY DISPOSED FOR LENGTHWISE MOVEMENT ALONG A PATH EXTENDING THROUGH SAID COLLECTION ZONE IN SPACED-APART RELATION TO WEB SECTIONS PASSING THERETHROUGH AND FACING THE ADHESIVE COATING ON SUCH WEB SECTION, MEANS OPERABLE TO DEPOSIT FLOCCULATED MATERIAL UPON SAID CONVEYOR BAND FOR TRANSPORT THEREBY INTO SAID COLLECTION ZONE, A FIRST PAIR OF ELECTRICALLY CONDUCTIVE MEMBERS EACH CONNECTED TO SAID SECOND OUTPUT TERMINAL AND DISPOSED FOR CONTACT WITH SAID CONVEYOR BAND AT SEPARATED POSITIONS ALONG THE MOVEMENT PATH THEREOF WITHIN SAID COLLECTION ZONE TO ESTABLISH THEREIN A GENERALLY UNIFORM ELECTRIC FIELD ACTING BETWEEN THE ADHESIVE COATING OF WEB SECTIONS PASSING THROUGH SAID ZONE AND CONVEYOR BAND SECTIONS PASSING THERETHROUGH BETWEEN SAID SPARATED CONTACT POSITIONS OF SAID FIRST PAIR OF CONDUCTIVE MEMBERS,

Claim 2

AN APPARATUS FOR APPLYING FLOCCULATED MATERIAL TO A MOVING WEB SURFACE COATED WITH AN ELECTRICALLY CONDUCTIVE ADHESIVE, WHICH COMPRISED A HIGH VOLTAGE ELECTRICAL SOURCE, AN ELECTRICALLY CONDUCTIVE MEMBER CONNECTED TO A FIRST OUTPUT TERMINAL OF SAID SOURCE AND DISPOSED FOR CONTACT WITH THE ADHESIVE COATING ON THE WEB TO ESTABLISH SAID COATING AT A GENERALLY UNIFORM ELECTRIC POTENTIAL CORRESPONDING TO TAHT OF SAID FIRST TERMINAL AND AT A HIGH VOLTAGE DIFFERENCE WITH RESPECT TO THE ELECTRIC POTENTIAL OF A SECOND OUTPUT TERMINAL OF SAID SOURCE, GUIDE MEANS DISPOSED FOR ENGAGEMENT WITH SAID WEB TO DIRECT THE MOVEMENT THEREOF LENGTHWISE ALONG A PREDETERMINED PATH PASSING THROUGH A FLOCCULATED MATERIAL COLLECTION ZONE, A CONVEYOR BAND OF LIMITED ELECTRICAL CONDUCTIVITY DISPOSED FOR LENGTHWISE MOVEMENT ALONG A PATH EXTENDING THROUGH SAID COLLECTION ZONE IN SPACED-APART RELATION TO WEB SECTIONS PASSING THERETHROUGH AND FACING THE ADHESIVE COATING ON SUCH WEB SECTION, MEANS OPERABLE TO DEPOSIT FLOCCULATED MATERIAL UPON SAID CONVEYOR BAND FOR TRANSPORT THEREBY INTO SAID COLLECTION ZONE, A FIRST PAIR OF ELECTRICALLY CONDUCTIVE MEMBERS EACH CONNECTED TO SAID SECOND OUTPUT TERMINAL AND DISPOSED FOR CONTACT WITH SAID CONVEYOR BAND AT SEPARATED POSITIONS ALONG THE MOVEMENT PATH THEREOF WITHIN SAID COLLECTION ZONE TO ESTABLISH THEREIN A GENERALLY UNIFORM ELECTRIC FIELD ACTING BETWEEN THE ADHESIVE COATING OF WEB SECTIONS PASSING THROUGH SAID ZONE AND CONVEYOR BAND SECTIONS PASSING THERETHROUGH BETWEEN SAID SPARATED CONTACT POSITIONS OF SAID FIRST PAIR OF CONDUCTIVE MEMBERS,
