Patent number: 10415210Abstract: Drive-over berm systems that protect raised sections of protective containment liners from truck and heavy equipment damage are disclosed. A ramped outer berm abuts an elevated portion of the liner, which may be raised to a desired height by an insert positioned under the liner. A ramped inner berm may about the elevated portion of the liner, and a connector plate may be used to secure the outer and inner ramped berms together. The height of the raised portion of the liner is selected to provide the desired sump capacity of the containment area.

Patent number: 8117686Abstract: Durable protective covers for drains and other holes are provided which prevent spills and unwanted liquids from flowing therein. The protective covers include a durable backing layer and a pliable, tacky sealing layer which conforms and adheres to a surface surrounding the drain to reduce or eliminate the flow of liquids into the drain. A low-density bonding layer is provided between the pliable, tacky sealing layer and the durable backing layer in order to provide significantly improved adherence between the layers.Type: GrantFiled: December 22, 2008Date of Patent: February 21, 2012Assignee: New Pig CorporationInventors: Beth P. Powell, R. Douglas Evans, Jr.

Publication number: 20120027520Abstract: A device for damming and diverting liquid on a spill surface has an elongated, pliable dike having a first end, a second end and an exposed surface. The exposed surface is inherently tacky so that it is adherable to the spill surface to prevent flow of liquid past the dike. The dike is preferably made from a substance, such as polyurethane, that is inherently tacky. The device provides improved tear resistance by one or more additions to the construction of the device. Some of the additions to the construction also improve UV resistance and/or chemical compatibility. A method for creating a liquid control zone on a spill surface utilizing the dike of the present invention is also disclosed.Type: ApplicationFiled: January 24, 2011Publication date: February 2, 2012Applicant: NEW PIG CORPORATIONInventors: Beth P. Powell, Robert J. Starr

Patent number: 5800908Abstract: The present invention is an improved device for delivering a release agent to fuser rollers employed in various printer devices, such as laser printers, fax machines, copier machines, etc. The release agent delivery device of the present invention comprises an elongated web of microporous membrane (e.g., expanded polytetrafluoroethylene) bonded to a substrate, filled with release agent, and mounted between two shafts. The web spans across the fuser roller so that the roller is simultaneously cleaned and oiled during normal operation. When the portion of the web in contact with the fuser roller becomes contaminated or expends its release agent supply, the web can be advanced to place a fresh surface in contact with the fuser roller.Type: GrantFiled: January 30, 1996Date of Patent: September 1, 1998Assignee: W. L. Gore & Associates, Inc.Inventors: Alex R. Hobson, Robert L. Sassa, Beth P. Powell
