US Patent:

7927492, Apr 19, 2011

Filed:

Jun 6, 2006

Appl. No.:

11/921682

Inventors:

William E Baird - Cohasset MA, US
William I. Young - North Scituate MA, US

International Classification:

C02F 9/14

US Classification:

210608, 210615, 210631, 210694, 210747, 210151, 21017003, 210282

Abstract:

Provided is a filter assembly for a bioremediating catch basin. The filter assembly comprises a container having at least one inlet and at least one outlet; a carrier substance, such as a foam, which carries a microorganism capable of digesting hydrocarbons; and optionally an adsorbent material. The filter assembly also optionally has structures for overflow conditions which allow the exit of water, but not floating contaminants from the catch basin. Also provided is a replaceable cartridge for the filter assembly. Also provided is a method for bioremediation of polluted water.

Appl. No.:

5/662662

Inventors:

William G. Baird - Winchester MA
Stanley E. Holbrook - South Acton MA
Jeremy A. Platt - Cambridge MA

Assignee:

W. R. Grace & Co. - Duncan SC

International Classification:

B29D 2301
B29D 2304

US Classification:

264514

Abstract:

A film combination including two plies of tack-free thermoplastic polymer and a hot-tacky vinylidene chloride crystalline polymer is prepared by coextruding the vinylidene chloride polymer outside melts of plies of the thermoplastic polymer.

US Patent:

Filed:

May 20, 1991

Appl. No.:

7/702752

Inventors:

William E. Baird - Cohasset MA
Peter J. Tolan - Scituate MA

International Classification:

C02F 140

US Classification:

210109

Abstract:

An automatic pumping system for removal of floating contaminants and oil and gasoline seepage from water wells. A vertically reciprocating cone-shaped member, like an inverted funnel, is moved between positions above and below the water surface. As it submerges, the inverted funnel collects the floating product within its circumference and transfers it to a collection space surrounding the cone. In the upper position, this collection space is sealed so that air may be blown into it while the collected product is driven out through a pickup tube to a collection sump for ultimate disposal. A second embodiment incorporates a hydraulic pumping system which operates in synchronism with the contamination collection and disposal system to create a cone of depression which draws the floating product into the space covered by the circumference of the reciprocating cone.

Assignee:

W. R. Grace & Co. - Duncan SC

International Classification:

C08F 1408

US Classification:

526343

Abstract:

A film combination including two plies of thermoplastic polymer and therebetween a vinylidene chloride crystalline copolymer film which is substantially devoid of pinholes and scratches and has low oxygen permeability is prepared by coextruding the copolymer as a melt between melts of outer plies of thermoplastic polymer. The film combination may be biaxially oriented or substantially unoriented and may be irradiated with high energy electrons. The film combination can be used for many packaging applications.

US Patent:

48481505, Jul 18, 1989

Filed:

Mar 9, 1987

Appl. No.:

7/023488

Inventors:

William E. Baird - Cohasset MA
Peter J. Tolan - Scituate MA

International Classification:

G01F 2320
G01F 2332

US Classification:

73296

Abstract:

A liquid level sensing apparatus for detecting leaks in storage tanks. A buoyancy member is at least partially immersed in the liquid, suspended from a pivoted, counterbalanced, parallelogram support arrangement with a radio frequency target sensing element for electrical readout of displacement. Two such apparatus are incorporated in a system with a provision for measuring a portion of the liquid of the tank in isolation from the remainder, in order to provide for temperature compensation.
