Abstract: A method of repairing a leaking spill container by lining the existing unit. Additionally the liner can be used to convert a single walled spill container into a double walled spill container.

Abstract: The present invention is directed to a brush for scrubbing and scratching the human body. The brush includes a base having a scrubbing surface extending from the front face of the base and an adhesive surface on the rear face of the base, for permanently attaching the brush to a wall with the front face being directed away from the wall. The scrubbing surface is preferably curved or rounded such that it is thicker in the center than along the sides.

Abstract: A seal for around a pipe penetrating through a wall. A rubbery reducer boot includes a flexible material-reservoir defined by a material curved-fold allowing a pipe-engaging tubular portion of the boot to be moved outward and inward from a relaxed position, and to be angled in extension relative to a stationary back portion of the boot. An end of the pipe-engaging tubular portion includes areas allowing the application of a hose clamp about the tubular portion to compress against the exterior of a secondary containment pipe adjacent the terminal end of the pipe, and the application of another hose clamp outward beyond the terminal end of the secondary pipe and clamping of the boot about a further-extending primary pipe. The back end of the boot near the material-reservoir includes an annular groove for receiving an annular first end of a tubular fitting assembly. A third and larger hose clamp is positioned about the back of the boot to compress and secure the boot sealed about the tubular fitting assembly.

Abstract: A leak testable bulkhead around a pipe penetrating through a wall, comprising a cylindrical hollow insert for partial passage through a hole in the wall, and through which the pipe passes. The insert has a perpendicular abutment flange preventing complete passage through the hole. Also provided are two rubbery gaskets for sealing, placed on each side of the hole against the wall with the flange abutting one gasket, and a wide-lipped washer against the other gasket. A nut threadably engaged on the insert and placed against the washer secures the insert, gaskets and washer tightly in place. Also included are two flexible reducer boots, a smaller of which is sealingly affixed over an un-threaded end of the insert adjacent the nut and reduces downward and sealingly affixes around the pipe passing through the insert. A larger of the reducers sealingly affixes onto the washer, and reduces downward and sealingly affixes over the pipe slightly beyond the smaller reducer so as to encase the nut and smaller reducer.

Abstract: An aliphatic organic acid fraction is separated from the kraft black liquor by subjecting the liquor to ultrafiltration, treating the resulting permeate by electrodialysis, acidifying the resultant deionate to about pH 4-5, separating the lignin solids which precipitate following this acidification, raising the pH of the separated solution to about 7-8 and finally subjecting the neutralized solution to electrodialytic water-splitting.
