Abstract: A free-standing stand that holds a hose and that automatically erects upon contact with a supporting surface and automatically collapses when removed from contact with the supporting surface. The free-standing stand includes a spine and a tripod. The spine has the hose be replaceably held thereto. The tripod is operatively connected to the spine in such a matter that when the tripod contacts the supporting surface the tripod automatically erects and when the tripod is removed from contact with the supporting surface the tripod automatically collapses.

Abstract: The present invention relates to a method for designing a system. This method includes obtaining a visual representation of one or more components of the ventilation system. One or more property values are assigned to each of the components of the system, which may be achieved using first program code. Geometrical information representing the visual representation and the property values of each component are exported to a data file using the first program code. Standards information relating to the property values are stored. The data file is then imported into a second software application and the data file and the standards information is used to generate a final design using the second software application.

Abstract: A portable ramp system particularly intended to assist temporarily handicapped persons with transport in and out of houses and buildings. Specifically, the system consists of several modular ramp members removably attached to one another to allow convenient wheelchair access to the application in question. Preferably constructed of wood, the members consist of hingedly-attached starter, rise, and straight panels, which may be folded down to a relatively compact size for the purpose of removal and transport. In addition, the system may include collapsible railing members to further assist the user. Finally, the horizontal panels of the ramp system may include a skid-resistant surface for the utmost in wheelchair traction. As such, the ramp system meets applicable ADA guidelines and provides a quick, convenient, and relatively inexpensive means for temporarily handicapped persons to access houses and similar structures.

Abstract: An apparatus for the proper shaped cutting of alternate components of sheet material fittings for subsequent joining as ductwork. The apparatus comprises a main support platform defined by a rectangular peripheral frame of side beams and end beams and a cutter head movably arranged over the platform to cut sheet material on the platform. A first shuttle table for receipt of a first piece of sheet material is supported on the platform. A second shuttle table for receipt of a second piece of sheet material is also supported alternately, on the platform. A roller bearing set is arranged on the platform to permit one of the shuttle tables to be moved onto the platform as the other of the tables is moved from the platform, to permit alternate pieces of sheet material to be cut by the cutter head over the platform in sequence with one another.

Abstract: A lawn mower propulsion system which is supported between the rear wheels and is pivotally mounted on the body by means of a pivot bolts, a forward driven shaft and a reverse driven shaft are rotatably mounted in the support, parallel to and on either side of the pivot bolts, friction rollers are fixedly mounted on the ends of the driven shafts to contact the rear wheels, the forward-drive rollers being larger than the reverse-drive rollers, pulleys are fixedly mounted on the driven shafts, a pair of pulleys is mounted on the offset drive shaft, a belt connects each of the pulleys on the offset drive shaft to a pulley on one of the driven shafts and are mounted to drive the rearmost driven shaft and the rear wheels in the forward direction and the forwardmost driven shaft and the rear wheels in the reverse direction, springs, connected to the support and the body, normally urge the forward-drive into contact with the rear wheels, the mower handle pivots downwardly against the support to pivot the forward-driv
