Filed:

Jul 25, 2002

Appl. No.:

10/202115

Inventors:

Robert J. Sparks - Upland CA 91786

International Classification:

B65B 3100

US Classification:

141 59, 141 11, 141 82, 141 67, 141325, 96224

Abstract:

A ventilating/sterilizing system for food-quality liquid storage tanks has a weatherproof overhead hood. Incoming air, drawn up into the hood is first filtered at the intake of an electric blower forcing the airflow through a main filter to be sterilized by ultraviolet radiation then heated for tank entry, where airflow drives out moisture and displaces air in the head region through a specially designed weather protective tank outlet vent with a removable cone-shaped dual-screen filter unit. A remote indicator light panel indicates normal operation and malfunctions. Stainless steel construction throughout minimizes deterioration and contamination. The main filter is enclosed in a housing mounted on a base unit containing the ultra-violet chamber, the heating chamber, and electrical components. The hood is hinged for intake filter access; similarly the blower assembly is hinged for main filter access for replacement or cleaning. Ultraviolet lamps in the base are accessible and replaceable from outside the unit without disassembly.

Abstract:

A modular display apparatus having at least one module which includes at least four elongated first members which are disposed in generally parallel spaced relationship. Two of the first members intersect a first plane along substantially the entire axial extent thereof. Two other of the first members intersect a second plane along substantially the entire extent thereof. The first and second planes are spaced. Four elongated second members are disposed in generally parallel relationship. Two of the second members are disposed in generally perpendicular relationship to two other of the first members and intersect the first plane along substantially the entire axial extent thereof. Two other of the second members are disposed in generally perpendicular relationship to two other of the first members and intersect the second plane along substantially the entire axial extent thereof. Each of the first members and each of the second members have a first slot disposed in a third plane which is generally perpendicular to the first and second planes. Each of the first and second members include a second slot which is disposed in a fourth plane which is disposed in generally perpendicular relationship to the first and second planes.
