Abstract: An apparatus for providing access to the casing of a burning oil well near the wellhead includes a sled-like carriage which is moved over the ground surface into a position straddling the well casing. A heat shield carried by the sled shields personnel and equipment thereon from the well fire. An excavator is mounted on the sled behind the heat shield for movement toward and beneath the heat shield to excavate a cavity around the well casing. A platform apparatus on the sled, including a pair of jaws openable to allow receipt of the casing, covers the excavated cavity into which a known well plugging device is moved for attachment to the well production pipe after the outer casing is cut away.
Abstract: An apparatus for stripping the scrap portion from a die cut blank includes a stripper pin carrier providing a pattern of stripper pins supported in a resilient compressible material layer in which the stripper pins are demountably embedded. The stripper pins may be inserted into the reslient layer to provide a pattern or patterns which will accommodate virtually any size, shape and location of scrap portions to be stripped from a blank. The stripper pins can be removed and reinserted in a different pattern to accommodate a different run of blanks of corrugated paperboard or the like. Programmable robotic control may be used for pin placement and removal. The stripper pin pattern, location and rotation are synchronized with operation of the upstream cutting die such that the die cut blanks move continuously under the stripper roll for automatic scrap stripping.
