Patent number: 7374669Abstract: A vacuum transport system suited to moving FOG-laden water. The system includes a first reservoir and at least one vacuum pump in fluid communication with the first reservoir and operable to produce a vacuum within the first reservoir. A first accumulator is positioned to collect FOG-laden water from a first FOG-laden water source. A first valve is operable to selectively provide fluid communication between the first accumulator and the first reservoir. FOG-laden water can be drained from the first reservoir into a grease interceptor disposed in the building exterior.Type: GrantFiled: April 26, 2005Date of Patent: May 20, 2008Assignee: Acorn Engineering Co.Inventor: Thomas K. Zinn

Patent number: 6694093Abstract: An antifreeze heating system which prevents the freezing of water present in an instant water heater of the type having a primary heater which remains inactive under static flow conditions. A secondary heater is placed within an enclosed housing volume of the instant water heater, and electrically connected to a temperature-sensitive switch which activates the secondary heater when a monitored temperature, such as the ambient temperature, falls below a threshold value.Type: GrantFiled: January 25, 2002Date of Patent: February 17, 2004Assignee: Acorn Engineering Co., Inc.Inventors: Donald E. Morris, Robert L. Wheeler

Patent number: 6687922Abstract: A stainless steel toilet resistant to corrosion by sea water. The toilet has a toilet bowl portion which is butt-welded to a rim. The welding is carried out while the inside surface of the weld line is flushed with argon gas. Similarly, a P-trap is butt-welded to an exit opening at the bottom of the bowl portion. A flush ring assembly is supported below the rim member. The result is a toilet which can be operated with sea water without corrosion for a period of years.Type: GrantFiled: October 21, 2002Date of Patent: February 10, 2004Assignee: Acorn Engineering Co.Inventors: Keith D. Marshall, Carlos J. Galeazzi, Darryl M. Boeltl

Patent number: 6311718Abstract: An activator valve for providing a time temporary vacuum at an output port which is normally at atmospheric pressure. The timed vacuum is provided in response to an increase in air pressure in an interruptible vacuum chamber, such as that by briefly opening the valve between the outside of the valve and the interruptible vacuum chamber. When this pressure increases, a diaphragm holding a magnet moves downwardly attracting a ferro-magnetic disk upwardly. The ferro-magnetic disk opens a valve between the output port and a main vacuum source port. This causes a vacuum to be drawn at the output port, which in turn operates a remote device which the activator valve is controlling. When the source of outside air to the interruptible vacuum chamber is closed the outside air is then drawn from the interruptible vacuum chamber, causing the magnet to once again rise and release the ferro-magnetic member, closing the valve between the main source of vacuum and the output port.Type: GrantFiled: July 6, 2000Date of Patent: November 6, 2001Assignee: Acorn Engineering Co.Inventors: V. Walter Hafner, Ron Hahn, Enrique P. Loreto

Patent number: 6158060Abstract: A toilet seat cover assembly for use as a combination toilet seat cover and auxiliary bathroom seat with self-positioning, retractable backrest. The assembly includes a cover which is hinged to either the toilet or a housing structure positioned on either side of the toilet. A backrest having a base portion and an adjoining upright portion is hinged to the cover at the base portion such that when the cover is raised from a closed position to an open position, the backrest pivots with the cover until it contacts a stopper. At such point, and as the cover is continuously raised, the stopper urges the backrest to hinge separately from the cover and to retract in a compact manner.Type: GrantFiled: September 13, 1999Date of Patent: December 12, 2000Assignee: Acorn Engineering Co.,Inventor: Robert L. Wheeler
