The plan also intended to establish 18 new institutes by working with the Ukranian Academy of Sciences. The eighth plan led to the amount of grain exported being doubled. About 14.5 million tonnes of grain were imported by the USSR. Détente and improving relations between the Soviet Union and the United States allowed for more trade. The plan's focus was primarily on increasing the amount of consumer goods in the economy so as to improve Soviet standards of living. While largely failing at that objective it managed to significantly improve Soviet computer technology. Leonid Brezhnev declared the slogan "Plan of quality and efficiency" for this period. During the eleventh five-year plan, the country imported some 42 million tons of grain annually, almost twice as much as during the tenth five-year plan and three times as much as during the ninth five-year plan (1971–1975). The bulk of this grain was sold by the West; in 1985, for example, 94% of Soviet grain imports were from the non-socialist world, with the United States selling 14.1 million tons. However, total Soviet export to the West was always almost as high as import: for example, in 1984 total export to the West was 21.3 billion rubles, while total import was 19.6 billion rubles. The last, 12th plan started with the slogan of "uskoreniye", the acceleration of economic development (quickly forgotten in favor of a more vague motto "perestroika") ended in a profound economic crisis in virtually all areas of Soviet economy and a drop in production. The 1987 "Law on State Enterprise" and the follow-up decrees about "khozraschyot" and self-financing in various areas of the Soviet economy were aimed at the decentralization to overcome the problems of the command economy. This plan, which would have run until 1995, only lasted about one year due to the dissolution of the Soviet Union in 1991. State planning of the economy required processing large amounts of statistical data. The Soviet State had nationalized the Odhner arithmometer factory in Saint Petersburg after the revolution. The state began renting tabulating equipment later on. By 1929, it was a very large user of statistical machines, on the scale of the US or Germany. The State Bank had tabulating machines in 14 branches. Other users included the Central Statistical Bureau, the Soviet Commissariat of Finance, Soviet Commissariat of Inspection, Soviet Commissariat of Foreign Trade, the Grain Trust, Soviet Railways, Russian Ford, Russian Buick, the Karkov tractor factory, and the Tula Armament Works.
