Abstract :
A recent development in inductive elevator control by Union Switch & Signal Division of Westinghouse Air Brake Company, Pittsburgh 18, Pa., has been installed at four stations; WWJ-TV (1,063 ft.), Detroit, Mich.; KVOO-TV (1,175 ft.), Sand Springs (seven miles from Tulsa), Okla.; WGBS-TV (996 ft.), Miami, Fla.; and WISN-TV (1,100 ft.), Milwaukee, Wis. These Union “TVL” electronic systems control the two-passenger elevators which glide up and down inside the structures.
