Abstract: A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange includes an inner surface and an opposing outer surface with a plurality of circumferentially spaced plateaus positioned thereon. Each plateau has a height above the outer surface. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. The first and second pipe flanges may couple to one another such that each plateau on the first pipe flange contacts a corresponding plateau on the second pipe flange.

Abstract: A wheel assembly includes a rigid wheel and an airless flexible tire with certain performance characteristics of a pneumatic tire. The rigid wheel includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire is mounted on the wheel and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.

Abstract: An airless flexible tire comprising a belt, drive lugs, and traction lugs. The drive lugs extend inwardly from the belt and form annularly spaced, rigid, high torque points. The traction lugs extend outwardly from the belt and are annularly offset from the drive lugs so as to form flexible sections that deflect radially inwardly when the tire engages the ground. Each traction lug has an effective height as a function of its actual height, the angle that the traction lug extends relative to a radial axis, the angle of the traction lug's distal surface, and the amount the tire deflects radially inwardly near the traction lug so as to at least partially equalize a rolling radius of the wheel to reduce torque generated near the high torque points.

Abstract: A wheel assembly for traversing a path along a ground surface having a layer of soil, the wheel assembly comprising a central support and an airless flexible covering mounted on the central support and having a plurality of rigid sections and a plurality of flexible sections. The outwardly protruding spokes urge the rigid sections into the layer of soil when the rigid sections contact the ground surface. The flexible sections flex inwardly when the flexible sections contact the ground surface so that the rigid sections and the flexible sections cooperatively form a corrugated pattern in the ground surface without urging the soil to side margins of the airless flexible covering, the corrugated pattern having a plurality of valleys formed by the rigid sections and a plurality of peaks formed by the flexible sections.

Abstract: An airless flexible tire including traction lug pairs each having a forward facing traction lug and a rearward facing traction lug cooperatively forming a divided Z or reverse divided Z shape. Each traction lug includes a lateral section and a central section. The central section extends from an end of the lateral section so as to straddle a centerline of the airless flexible tire and includes a number of discrete sidewalls. The discrete sidewalls are different sizes and angled relative to each other. The central sections of paired traction lugs form a space dividing portions of the Z or reverse Z shape. The central sections of nearest traction lugs of adjacent traction lug pairs form a space dividing the adjacent traction lug pairs.

Abstract: A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange is of generally annular disc shape with an inner surface, an opposing outer surface, an inner edge, and a radially-spaced outer edge. Each pipe flange includes an annular outer recess formed on the outer surface adjacent to the inner edge. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. Each liner flange may be positioned within the outer recess of a successive one of the pipe flanges.
