Abstract: A method for retrieving an inventory item based on a handling robot, where the handling robot includes: a storage frame; and a material handling device installed on the storage frame, and including a telescopic arm and a manipulator installed to the telescopic arm; and the method for retrieving an inventory item includes: driving, by the telescopic arm, the manipulator to extend to a preset position of warehouse shelf along a preset horizontal reference line; loading, by the manipulator that is remained on the reference line, the inventory item located in the preset position; driving, by the telescopic arm, the manipulator loaded with the inventory item to move to the storage frame along the reference line; and unloading, by the manipulator that is remained on the reference line, the inventory item to the storage frame.

Abstract: An apparatus to facilitate field assessment of static structure sites to provide data in a predetermined format acceptable to a taxing authority, including a personal computing device having a graphic display screen, a user interface, and application software. The user interface is arranged to accept alphanumeric data provided by a user of the apparatus and also accept graphic input from the user representative of structural features of the static structure. The application software is arranged to provide a real-time display on the graphic display screen of dimensional data associated with the graphic inputs as they are entered by the user. The application software is also arranged to compute dimensional attributes of enclosed polygons resulting from the graphic input by the user.

Abstract: A door holder and a door closer and, in particular, and improvements in door holders and closers for use in screen doors, storm doors or any type of door which has the need for a device for maintaining the door in a particular orientation and/or for self-closing of the door.

Abstract: There is disclosed a system for suspending a rigid panel in an opening formed in a barrier structure. The system comprises a sleeve of flexible material having an anchor portion attachable to the perimeter of the opening and a grip portion opposite the anchor portion. The grip portion is contoured so as to form a channel disposed between an anterior extension and a posterior extension of the grip portion. Each of the anterior extension and the posterior extension comprises a fold of the flexible material having an apex at its inner end. A first elongated tensioning member received within the apex of the anterior extension and a second elongated tensioning member received within the apex of the posterior extension. The edges of the panel are received within the channel and the first and second elongated tensioners may be made sufficiently taut to prevent easy removal of the panel from the channel. Also disclosed is a method of suspending a rigid panel in a barrier structure employing structure as disclosed.

Abstract: A panel system includes a first skin, a second skin, a web core constructed from sheet material for securing the skins together in a spaced, sandwich relationship, and a connecting means for affixing the web core within the skins. The web core includes a plurality of spaced apart longitudinal members having longitudinally spaced projections extending therefrom and further having transversely aligned, longitudinally spaced slots therein. The web core further includes a plurality of spaced-apart, transverse cross members each having spaced slots therein receiving the longitudinal members at corresponding transversely aligned slots thereof to provide an interlocked grid between the first and second skins. The grid is connected to the skins utilizing the projections, which extend through slits in the skins to facilitate welding or otherwise bonding the components.

Abstract: An apparatus for hanging objects such as bird feeders or planters on the edge of a building of a type having a gutter and drip guard thereon. An elongated member has a first end and a second end and an intermediate portion of the elongated member is operably supported by an upper edge of an outer wall of the gutter. An upwardly extending flange is operably attached to a first end of the elongated member and the upwardly extending flange is disposed between a drip guard and a first wall of the gutter closest to the edge of a roof. A hook is operatively attached to the elongated member at a place spaced from the flange for hanging objects therefrom.

Abstract: A shingle is provided that is especially adapted for application to hips or ridges of a roof. In a preferred embodiment, the shingle is a laminated multi-layer shingle, bent or curled into a preformed shape that is reasonably close to the shape that it will have in the installed condition. The shingle layers are connected together in more than one zone, or in one large zone after sliding relative to one another as the shingle is bent or curled. Preferably, such connection is by means of an adhesive.

Abstract: A railway hopper car includes a curved roof having a roof sheet provided with lateral edges each joined to the top of a car side sheet by a top chord assembly. Each top chord assembly includes a top chord fully disposed within the car interior and having a vertical leg joined to the interior surface of a side sheet while an opposite inclined or angular leg is joined to the interior surface of the roof sheet. A curved cover overlies both top chord legs and forms, with the roof sheet and side sheet, a smooth continuously descending profile from the top centerline of the car roof to each of the car sides.
