Abstract: A method for manufacturing a torque-transmitting assembly includes turning an inner component and machining an outermost surface of the inner component such that the outermost surface of the inner component has a continuous convex shape. The method further includes turning an external component and machining an innermost surface of the external component such that the innermost surface of the external component has a continuous convex shape. The method also includes heating the innermost surface of the external component to expand a size of the innermost surface after machining the innermost surface of the external component and placing the heated external component onto the inner component while the inner component is maintained at room temperature.

Abstract: A pipe rotator assembly includes a frame upon which a cylindrical pipe is supportable, and a wheel rotatably coupled to the frame and engageable with the pipe for imparting rotation thereto in response to rotation of the wheel. The pipe rotator assembly additionally includes a drive shaft coupled to the wheel for transferring torque thereto, causing the wheel to rotate, and a drive unit for providing torque to the drive shaft. The drive unit includes an electric motor and an onboard power source for powering the motor.

Abstract: A method for manufacturing a torque-transmitting assembly includes: turning an inner component (b) machining an outermost surface of the inner component such that the outermost surface of the inner component has a continuous convex shape; (c) turning an external component; (d) machining an innermost surface of the external component such that the innermost surface of the external component has a continuous convex shape; (e) heating the innermost surface of the external component to expand a size of the innermost surface after machining the innermost surface of the external component; (f) placing the heated external component onto the inner component while the inner component is maintained at room temperature; and (g) holding the inner component and the external component in place until an interface between the innermost surface of the external component and the outermost surface of the inner component reaches the room temperature.

Abstract: The present invention is directed to apply plates, clutch plates, reaction plates and backing plates utilized of friction clutch packs, brake housings, clutch hubs, clutch housings, accumulators, spline sets, valve bodies and wear surfaces against which bushings, seals, springs and similar components slide and contact which are utilized in motor vehicle automatic transmissions, are fabricated of aluminum and include an electro ceramic coating deposited thereon. Such components exhibit reduced weight relative to similar components fabricated of steel as well as extended service life due to both the hardness and porosity of the ceramic coating.

Abstract: A panelized roof system comprises a plurality of panels for positioning on a roof substrate. The panels comprise a foam insulation board with synthetic fiber mat and a rubber sheet bonded to the top surface thereof. A plurality of fasteners penetrates the sides of the panels and secure the panels to the roof substrate. The panelized roof system is completed and rendered waterproof by a plurality of synthetic fiber reinforced rubber strips which are applied with adhesive or adhesive tape to the joints between the panels so as to overlap the adjacent fasteners securing the panels to the roof substrate.

Abstract: A panelized roof system comprises a plurality of panels for positioning on a roof substrate. The panels comprise a foam insulation board with a rubber-modified bitumen-saturated synthetic fiber mat bonded to the top surface thereof. A plurality of fasteners penetrates the sides of the panels and secure the panels to the roof substrate. The panelized roof system is completed and rendered waterproof by a plurality of rubber-modified bitumen-saturated synthetic fiber strips which are applied with hot-mopped asphalt or other non-torched adhesive to the joints between the panels so as to overlap the adjacent fasteners securing the panels to the roof substrate.
