Abstract: Provided are a vehicle end skeleton structure and a rail vehicle having the same. The vehicle end skeleton structure comprises: a roof structure, the roof structure being a closed frame structure; and an end energy absorption structure, the upper end of the end energy absorption structure being connected with the roof structure, and the lower end of the end energy absorption structure being connected with a chassis. The technical solution provided in the present invention can solve the problem in the conventional art in which the collision performance of a vehicle end skeleton structure cannot meet current demands.

Abstract: Racking assemblies for solar panel installations are provided. The racking assemblies may include a series of posts arranged in two parallel rows and anchored to the ground or other suitable surface. Purlins may be coupled to and may span the posts of each row. Specialized clamps may be used to attach the purlins to a series of mounting rails. The mounting rails, in turn, may support an array of solar modules.

Abstract: There is provided a roof for a vehicle where each one of its right and left side wall has at least a first and a second door opening. The roof structure comprises a lattice structure and an outer shell. The lattice structure has two pairs of longitudinal segments adapted to be located at a top portion of the first and second door openings and two diagonal segments. One diagonal segment extends from a first longitudinal segment adapted to be located at the first door opening in the right wall to a second longitudinal segment adapted to be located at the second door opening in the opposite wall. The other diagonal segment extends from a first longitudinal segment adapted to be located at the first door opening in the left wall to a second longitudinal segment adapted to be located at the second door opening in the opposite wall. The outer shell is placed atop the lattice structure and extends from a region proximate the front end to a region proximate the rear end of the vehicle.

Abstract: A fiberglass railcar roof that includes a fiberglass surface with a central portion and a peripheral portion adapted to be joined to the upper edge region of a railcar. In some embodiments, the roof includes plural elongate fiberglass ribs extending transverse to the longitudinal axis of the fiberglass surface. In some embodiments, the roof is adapted for use on refrigerated, high cube and cryogenic railcars. Methods for forming the invented roofs and roof panels are also disclosed.

Abstract: A die system for use in formation of a welded flashing, comprising a body portion comprised of a conducting material, the body portion having a first end and a second end; an indent portion at the first end of said body portion adapted to accept a portion of the flashing during welding; and where the portion of the flashing accepted in the indent portion of the body portion is folded away from an operational connection between the first end of the body portion and a welder during welding.

Abstract: The invention relates to a surgical instrument for minimally invasive surgery, in particular in the form of pincers or forceps. The instrument comprises at least two gripping elements, which for the purpose of gripping can be moved like forceps towards one another in a gripping direction or apart from one another in the opposite direction. At least one gripping element comprises at one end a first limb and a second limb, and at least one flexible bending region. The limbs are spaced apart from one another in the gripping direction with at least the first limb of each gripping element disposed within a guide sleeve and movable in a longitudinal direction of the guide sleeve, relative to the second limb of the gripping element in such a way that during a relative movement of the limbs with respect to one another the associated gripping element can be moved in the gripping direction.

Abstract: A roof jack or vent seal which is unitarily vacuum formed of polypropylene synthetic rubber polymer and a U.V. stabilized pigment and which has a planar roof covering with a central upstanding frusto-conical section including stepped graduated portions, with the region between each graduated portion capable of flexing to accommodate differences in the roof pitch.

Abstract: A curved roof construction for a hopper type rail car wherein a plurality of roof support webs extend transversely between opposed car side walls at spaced intervals to each other. These webs provide support for a plurality of large roof panels which are disposed in generally end to end relationships and define the roof surface. The support webs have outwardly curved or bowed conformations between opposed ends thereof so that the roof panels will be similarly bowed. The roof panels are installed so as to define an elongated roof hatch opening generally centrally between and longitudinally of the car side walls. A roof coaming is associated with the roof panels in an adjacent surrounding relationship with the hatch opening. Elongated side plates fixedly secured to the car side walls adjacent to the top edges thereof provide mounting surfaces for the outer side edges of associated ones of the roof panels.
