John F Krumme: Slotted autoregulating heater. Metcal, Hall Myers & Rose, January 5, 1988: US04717814 (196 worldwide citation)

Designation of specific heating zones and increase in minimum resistance relative to prior heaters of the type to which the present invention pertains is achieved, together with flexibility or bendability, if desired, by slotting the outer conductor of the heater. Additional flexibility is also achi ...
