Sorel's Salvage was a cover identity for the secret Federation facility "The Yard". Circa 2269, when the wayward Klingon starship Heart of Qo'noS approached the base, Spock hailed them, identifying himself as Sorel, a salvage yard proprietor. This had the desired effect of convincing the Klingon not to investigate. (TOS short story: "Devices and Desires")
