International Classification:

B23Q 3/18

US Classification:

269 58, 269 55, 269 56, 269 60

Abstract:

A fine positioner module is used to perform fine positioning of a device that is pressing against a work surface. In some embodiments, the fine positioner module includes a contact member for making contact with a work surface, a position adjustor for using the contact member to move the device along the work surface, and an actuator for relieving pressure of the device against the work surface while the contact member is used to move the device along the work surface.

Abstract:

A vented coke oven door includes a door frame having a vertical face surface carrying a plug assembly having a central vertical internal opening to conduct coke oven gas generated at the bottom of a coal charge in a coke oven chamber. The plug assembly includes a plurality of U-shaped refractory plug segments arranged in an end-to-end aligned relation with leg sections of each U-shaped segment extending horizontally into an abutting relation with the face surface of the door frame. Each leg section carries either an embedded hooked end or a T-shaped head of a threaded fastener which is supported by the door frame so that the leg sections are unrestrained against movement toward and away from each other in response to a thermal gradient across the wall thickness of the refractory plug segment. A backing plug plate is fitted into a recess in the leg sections of each plug segment to provide a closure wall to the U-shaped configuration of the segments and forms the vertical passageway for conducting coke oven gas. The backing plug plate has an exposed layer of cast refractory overlying a layer of insulation used to protect the door frame.
