Title: Conducting rollers for continuous plating - having copper sheath coated with chromium and interlayer of nickel
Inventor: QUARZ WERNER
IPC: C25D7/06
Filed: 1974-04-18
Abstract: Conducting roller, for transmitting a large electric current, consists of a roller mounted on a shaft connected to an electrical power source. The outer surface of the roller is of copper upon which is a coating of chromium. A layer of Ni is inserted between the Cr and the Cu. This Ni layer is applied by a galvanising process. The roller is used in the continuous electro-plating of metal sheet where the sheet is gripped by such rollers and runs through an electrolytic bath. Chromium coatings are used to protect the Cu surface but at higher pressures this can become damaged and the electrolyte then attacks the Cu. The Ni is used as a buffer zone between the two layers and improves the strength and durability of the roller, thus permitting higher speeds on the plating plant.

Title: Vehicle wheel drive system - has extending spokes causing foot rollers to roll over output ramp
Inventor: SANDER THEODOR
IPC: B60B19/00
Filed: 1975-08-11
Abstract: With the wheel system it is claimed that the spokes extend to maximum height and cause the foot rollers to roll over the output ramp. This forms the only continuous load, directly thrusting the axle into its end position. This tends to push the vehicle axle forward, so that its own weight tends to assist forward motion. The spokes are movably arranged around an annular guide eccentrically carried in the wheel centre.
