Abstract
Abstract An electrostatic generator comprises a pair of side by side disposed endless chains, each chain comprising metal pellets insulated from one another, with metal strips interconnecting the pellets of one chain with oppositely-disposed pellets of the other chain. Induction electrodes are provided for charging the pellets and strips as the chains are made to rotate together, and for transferring the charges to a high voltage terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
For electrically charging a high voltage terminal, the combination comprising a series of electrically conducting members of elongated form having smooth uncovered external surfaces, mechanical linkages interconnecting and electrically insulating adjacent members from one another thereby to arrange the members in substantially parallel side-by-side array in an endless chain, a charging station and discharging station of which at least the former comprises induction electrode means disposed on both sides of the elongated members, the discharging station being arranged for the transfer of charge from the members to the high voltage terminal, and means for driving the endless chain along a path of travel from the charging station to the discharging station.
Claim 2
Dependent Claim
111 words
For electrically charging a high voltage terminal, the combination comprising a series of electrically conducting members of elongated form having smooth uncovered external surfaces, mechanical linkages interconnecting and electrically insulating adjacent members from one another thereby to arrange the members in substantially parallel side-by-side array in an endless chain, a charging station and discharging station of which at least the former comprises induction electrode means disposed on both sides of the elongated members, the discharging station being arranged for the transfer of charge from the members to the high voltage terminal, and means for driving the endless chain along a path of travel from the charging station to the discharging station.
Claim 3
Dependent Claim
26 words
The combination as claimed in claim 1, wherein the mechanical linkages interconnecting adjacent elongated members comprise link means spaced apart transversely of the path of travel.
Claim 4
Dependent Claim
72 words
The combination as claimed in claim 2, wherein the link means comprises a laterally spaced pair of endless chain structures each of which is formed by a plurality of electrically conductive bodies connected to each other by links of insulating material, each said elongated member being attached to and extending between one electrically conductive body of one said chain structure and on oppositely disposed electrically conductive body of the other chain structure.
Claim 5
Dependent Claim
43 words
The combination as claimed in claim 3, provided with spaced pairs of pulleys, the said chain structures moving around the said spaced pairs of pulleys which are electrically conducting for carrying electrical charge to or from a said charging station or discharging station.
