CREATE TABLE table_629 ("Tag ID" TEXT, "Application" TEXT, "Torque Rating" FLOAT, "1st" TEXT, "2nd" TEXT, "3rd" TEXT, "4th" TEXT, "5th" TEXT, "6th" TEXT, "Rev" TEXT, "Input Splines" FLOAT, "Output Splines" FLOAT)

What application has a 6th ratio of 0.50:1 and 350 as a torque rating?
SELECT "Application" FROM table_629 WHERE "6th" = '0.50:1' AND "Torque Rating" = '350'
SELECT "Application" FROM "table_629" WHERE "6th" = '0.50:1' AND "Torque Rating" = '350'
