Abstract: The computer-implemented method for glass bending includes obtaining a deviation of a real shape of a glass from a desired shape of the glass, the glass is produced by a glass bending process; determining a variation of at least one parameter associated with the glass bending process, at least in part based on the deviation of the real shape from the desired shape; and adjusting the at least one parameter based on the variation for compensation of the deviation.

Abstract: Disclosed is a method of continuously raising and lowering an oilfield shaft drillstring using a double traveling slips device, wherein two sets of traveling slip mechanism form the two traveling slip mechanisms to form the two traveling slips device, the first set of traveling slip mechanisms and the second set of traveling mechanisms are respectively mounted on a pithead apparatus (10) to constitute a continuous raising and lowering system. In the process of raising and lowering an oilshaft drill-string, the slips (1, 4) of each set of traveling slip mechanisms alternately clamp or release the drillstring, ensuring a continuous raising and lowering motion for the drillstring (9) from beginning to end under the clamping of the slips, and achieving uninterrupted operation. Further disclosed is a double traveling slips device.
