Input: Article: In 1634, the Mughal emperor extended his hospitality to the English traders to the region of Bengal, and in 1717 completely waived customs duties for the trade. The company's mainstay businesses were by then cotton, silk, indigo dye, saltpetre, and tea. The Dutch were aggressive competitors and had meanwhile expanded their monopoly of the spice trade in the Malaccan straits by ousting the Portuguese in 1640–41.

Input: Article: Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal "flow" of time to an earthbound observer. In this view, all points in time (including future times) "persist" in some way. Time travel has been a plot device in fiction since the 19th century. Traveling backwards in time has never been verified, presents many theoretic problems, and may be an impossibility. Any technological device, whether fictional or hypothetical, that is used to achieve time travel is known as a time machine.

Now answer this question: A time machine is known as any technological devise that is used for what purpose?

Output:
to achieve time travel
