Patent number: 6547220Abstract: A control system for a pneumatic hoist limits the velocity or acceleration of a load attached to the hoist. The control system includes a controller and a valve. The controller provides a variable gain between an actuator, which controls the speed of the hoist, and the valve, which controls fluid flow into the hoist, thereby controlling the velocity or acceleration of the load. As the velocity or the acceleration of the load reaches a predetermined maximum value, the control system proportionally reduces the gain between the actuator and the valve, thereby closing the valve and reducing the velocity or acceleration of the hoist.Type: GrantFiled: January 31, 2001Date of Patent: April 15, 2003Assignee: Wilmington Research and Development CorporationInventor: Douglas A.

Patent number: 6547235Abstract: A stopper member regulates the leading edges of sheets stacked on a sheet supply tray. In a first position of the stopper member, the sheets on a sheet supply tray are prevented from advancing into a paper feed path, and in a second position, the sheets drawn out by a draw-out device pass. The stopper member can be moved to a third position between the first and second positions. The displacement to the third position from the first position is associated with the lowering of the draw-out device for drawing out the sheets from the sheet supply tray, and the displacement from the third position to the second position is accomplished by the leading edge of a sheet drawn out by the draw-out device. This structure prevents damage to the original stacked on the sheet supply tray, and attains a simple structure and a low cost apparatus.Type: GrantFiled: December 17, 2001Date of Patent: April 15, 2003Assignee: Nisca CorporationInventor: Akiharu Higaki

Patent number: 6547238Abstract: A pivotally mounted bail actuator is pivotally moved from its home position to an elevated position by the leading edge of a sheet of paper exiting from sheet path exit rollers of a printer. The pivotally mounted bail actuator has a wire bail extending for more than half of the sheet width. When the sheet exits from the sheet path exit rollers, both the pivotally mounted bail actuator and the sheet simultaneously fall by gravity, and the wire bail contacts the sheet to remove any longitudinal beam and to create a lateral beam extending the width of the sheet. A rear portion of the sheet falls onto an upper support surface with most of the sheet falling onto a lower support surface. If the sheet does not have a longitudinal beam, a lateral beam is created by the height difference of the two support surfaces on which the sheet is supported. The sheet is aligned on the upper support surface.Type: GrantFiled: March 30, 2001Date of Patent: April 15, 2003Assignee: Lexmark International, Inc.Inventors: Jeffrey Allen Ardery, Michael Kurt Gordon, Daniel Joseph Westhoff

Patent number: 6547259Abstract: The jaw assembly includes a master jaw and an insert jaw. An engagement surface on the master jaw provides a mounting surface for the insert jaw. The master jaw is contoured to provide a minimum of mass opposite the mounting surface and opposite the engagement surface to minimize the total rotating mass when the jaw assembly is in operation. In operation, a force is applied substantially perpendicular to the engagement surfaces between the insert jaw and master jaw such that the engagement surface experiences the force rather than the insert fastener.Type: GrantFiled: September 28, 2001Date of Patent: April 15, 2003Assignee: Dura-Hog, Inc.Inventor: Michael Fitzpatrick

Patent number: 6547263Abstract: A convertible cart and container may be assembled by folding a blank of paperboard and attaching a wheeled carriage thereto. The blank includes a floor panel connected to front and back panels along fold lines, the back panel having side panels connected thereto along fold lines. The blank includes a plurality of lines of weakness which facilitate separation of the assembled cart into an upper handle portion which may be discarded and a container portion. The assembled cart conveniently includes an opening in a front panel and a pair of doors which are hinged to the front panel along fold lines to permit access to the chamber within the cart while obscuring the contents from view. The cart includes a top flap portion which may be separated from the upper handle portion and folded over a substantially rectangular box-type container for enclosing items received in the container and permitting shipping of the reduced size container without the need for emptying the contents for conversion.Type: GrantFiled: October 10, 2000Date of Patent: April 15, 2003Assignee: Pitsco, Inc.Inventors: Todd McGeorge, Bill Holden

Patent number: 6547264Abstract: A service cart leg extender assembly for attachment to a leg of a service cart that lengthens the leg of the service cart to a chosen length. The leg extender assembly includes an apparatus that augments the leg of the service cart through an easy to accomplish, reversible effect. The leg extender assembly disposes the components of the service cart at a higher elevation without diminishing stability of the service cart. The leg extender assembly is also embodied in a two portion apparatus with an upper portion including a notch that allows for securing the leg extender assembly to a leg of the service cart. The leg extender assembly is also embodied in a two portion apparatus with an upper portion including a hole that allows for securing the leg extender assembly to a leg of the service cart. One such leg extender is connected to each leg of the service cart to be elevated.Type: GrantFiled: November 19, 2001Date of Patent: April 15, 2003Assignee: Sunex International, Inc.Inventor: John H.
