This invention relates to an arrangement for sealing a closed chamber in which equipment is to be replaced and especially to a chamber in which equipment is to be replaced while the chamber is to be maintained closed. The arrangement includes a channel filled with a fluid, such as water, and a skirt arranged to extend into the fluid to form the seal. As the skirt extends down into the liquid, a portal space is formed at the opening in the chamber and the opening preferably includes a gate for closing the chamber from the portal space and the outside.

Arrangement for sealing a closed production system

This invention relates to a coupling system for connecting one or more fluid conduits wherein the system is adapted for lateral entry of one pipe or conduit to the other. The coupling system is also suited for making a connection in an environment which is relatively inaccessible to personnel and may be remotely operated.

Lateral entry remotely operated coupling system

An apparatus for adjusting the path that a web formed by striking a contoured surface baffle will take as it descends to a collection surface, in which the baffle is mounted on a pivot plate which will pivot and cause the web to leave the contoured surface baffle at the desired angle.

Apparatus for forming a fibrous sheet

This invention relates to flash spinning a plexifilamentary film-fibril strand and laying it down into sheet material including the step of subjecting the strand to an electrostatic charge. The invention is particularly focused on cleaning, and maintaining clean, the target plate of the electrostatic charging system by scrubbing or scouring the surface of the target plate with a highly abrasive brush moving at a relatively high speed. The target plate is selected to be abrasion resistant.
