The three methods Leeuwenhoek cheap to make his lensesgrinding blowing and drawing.First came eyeglasses. For centuries after Alhazen and Roger Bacon first described lenses people ground crude glass lenses to aid sight. Magnification of two or three times was usually sufficient. In addition the human eye doesnt need very much of the lens at any given time so the lens does not need .
Never start a machine until you are sure all parts are in their proper places. If it is a machine that operates with gears check the gear position. You must be aware of the lock-out procedures that are to be followed before repairing or cleaning any machine. Lock-out procedures must be clearly posted by management near each machine.
