Abstract:

A filter wrap for a cylindrical filter has a sheet with an interior side facing the filter when the sheet is wrapped on the filter, and an exterior side. It also has an edge defining a main opening to the interior for receiving the filter. At least one strap is provided for the wrap with one end attached to the sheet. The strap has another accessible distal end. Pulling on the strap(s) everts the sheet as it is pulled off of the filter. This results in trapping debris residing on the exterior of the sheet within the sheet once it is everted during removal of the wrap from the filter. Installation and removal can be performed while the protected equipment remains in operation.

Abstract:

A wellhead slip formed from a plurality of slip segments adapted to be arranged in a closed circular fashion around a tubular member so as to form a plurality of vertical gaps all but one of which are defined as "hinge" gaps, the remaining gap being defined as an "opening" gap, the slip segments being provided with aligned circumferential grooves constituting, in effect, a peripheral groove for the complete slip. A hinge yoke is received in the circumferential grooves in the area of each hinge gap and spanning the hinge gap, each hinge yoke being provided with a notch adjacent each of its opposite ends and facing outwardly from the groove. A hinge pin passes through holes above and below the groove in the area of each notch whereby the notches are received behind the hinge pins and whereby all of the slip segments can be moved hingedly outwardly from the closed circular position by opening at the opening gap. A spring clip is received in the ends of the circumferential grooves of the adjacent segments in the area of the opening gap and is provided with a vertical width slightly less than the width of the grooves. A pair of latch pins are received in holes above and below the groove in the slip segments on opposite sides of the opening gap.
