Patent number: 7162762Abstract: An air operated dock leveler is provided to selectively raise and lower a deck with an extendable lip. The deck includes a downwardly extending deck lift arm. An air lift assembly includes a single chamber, inflatable bag positioned between a stationary lower bag support and movable upper platform. A pull line is secured to the platform and the deck lift arm. When actuated, a blower inflates the bag and raises the platform. The pull line pulls the deck lift arm forward and raises the deck to an inclined position. When the blower is turned off, the ramp descends until the now extended lip engages the bed of a truck. After loading or unloading the trailer, the bag is reinflated to raise the ramp and retract the lip. The blower is then turned off, and the ramp descends to its stored position.Type: GrantFiled: June 2, 2006Date of Patent: January 16, 2007Assignee: Nordock, Inc.Inventor: Denis Gleason

Patent number: 7089955Abstract: The present recreational vehicle water warming and circulating system uses the heated water in the water heater to heat the on-board water supply when the outside air temperature drops below the freezing point of water. The system includes a holding tank for containing a majority of the on-board water supply, and heated and cold loops that supply heated and cold water to various fixtures in the recreational vehicle. When temperature sensors sense a potentially freezing condition, a control circuit opens one or more solenoid valves to open the one or both loops to return undispensed heated or cold water to the holding tank. The control circuit closes the solenoid valves when the potentially freezing condition is no longer detected by the temperature sensors.Type: GrantFiled: July 20, 2005Date of Patent: August 15, 2006Inventor: Grant T.

Patent number: 7054717Abstract: The present invention pertains to a robotic wash cell including a six-axis robotic arm and end effector equipped with nozzles that spray unheated, solvent free, pure water at high-pressure to clean or debur objects by maintaining the nozzles in close proximity and substantially normal to each surface being cleaned or edge being deburred. The robotic cell wash is particularly useful for cleaning contaminants such as oil and grease from items having more complex shapes. The six-axis robotic arm positions the nozzles and their sprays substantially normal to each surface being cleaned or deburred. The nozzles produce a multi-zone spray pattern with a continuous effective cleaning zone. A water recycling and pressurizing system collects the used water, separates out the oil and grease contaminants to a level of about 5 ppm, and pressurizes the pure water to about 3,000 psi for washing operations or about 6,000 psi for deburring operations.Type: GrantFiled: August 26, 2004Date of Patent: May 30, 2006Assignee: ABB Inc.Inventor: Stephen J.

Patent number: 7013519Abstract: The present invention pertains to a mechanically actuated dock leveler with a mounting frame secured in a pit of a loading dock, and a deck assembly with a deck and extendable lip. A deck lift assembly biases the deck to move from a parked position to a raised position to activate a lip extension assembly. As the deck is “walked down”, the lip is extended and the lip extension assembly is deactivated in a controlled manner so that the deck and lip reach an engaged position against the trailer and are kept in place by a hold down mechanism. The deck assembly has a float housing with a slot for releasably engaging the lift assembly to achieve a range of float positions where the deck and lip rest on and float with the trailer as it is loaded and unloaded. The deck assembly has a durable combined lip lug and header plate hinge construction.Type: GrantFiled: November 29, 2004Date of Patent: March 21, 2006Assignee: Nordock, Inc.Inventor: Denis Gleason

Patent number: 6286659Abstract: A conveyor roller for motorized conveyors including a lateral friction torque limiting mechanism to drive a roller tube via a rotation driving element. The torque limiting mechanism includes a first friction surface associated with the roller tube and a second friction surface associated with the drive element. The second friction surface is made of a magnetic material. The first and second friction surfaces are applied one against the other through a magnetic field generated by permanent magnets. When the force required to rotate the roller tube is higher than the frictional force between the first and second friction surfaces, slippage will occur between the first and second friction surfaces, stopping the rotation of the roller. The drive element includes ventilation channels to thereby cool the friction surfaces.Type: GrantFiled: December 11, 1998Date of Patent: September 11, 2001Assignee: GEBO Conveyors, Consultants & Systems, Inc.Inventor: Zmaj Petrovic

Patent number: 6246897Abstract: A system and method for the acquisition of preferential arterial and venous images is disclosed. The invention includes setting a noise level in the phase image, that is proportional to the velocity encoding value, at a threshold level above the venous signal but below the arterial signal during a systolic portion of the cardiac cycle and acquiring a phase contrast MR image during the systolic portion that effectively acquires the arterial signal and suppresses the venous signal. During the diastolic portion of the same R—R interval, the velocity encoding value is then set to establish a noise threshold level in the phase image lower to a value below the venous signal but above the arterial signal to acquire the venous signal and suppress the arterial signal. In this manner, either an arterial only image or a venous only image can be displayed. Alternatively, the images can be combined to create a higher SNR arterial and venous image.Type: GrantFiled: December 11, 1998Date of Patent: June 12, 2001Assignee: General Electric CompanyInventors: Thomas K.
