Abstract: Methods for closing a seam in a paper processing belt having a coating of polymeric resin material require the covering of the seam on the uncoated side of the belt with an encapsulating material, so that the seam will have compression properties substantially identical to those of use of the remainder of the belt. In one method, a viscous paste obtained by mixing a polymeric resin material with a blowing agent is used. Following installation of the fabric, or belt, on a paper machine by closing its pin seam with a pintle, the seam region on the non-paper side of the fabric or belt is impregnated with the viscous paste. The seam region is then heated to a temperature to activate the blowing agent and to create a foam from the paste. The foam fills voids in the seam region, and may pass out through the slit in the coating over the seam. Raising the temperature further cures the foam and may glue the slit closed.

Abstract: A plough drive employs a plough box mounted face to face on a side plate or intermediate plate of a machine frame of a scraper-chain conveyor. A rotatable chain wheel is disposed in the box for driving a chain coupled to the plough. A chain stripper seats in a pocket in the box and is locked therein. The stripper can be withdrawn laterally from the pocket. The stripper is connected to an adjustable annular collar on the casing of a gearing unit which drives the chain wheel and is detachably secured to the side of the box remote from the frame. The gearing unit and stripper can thus be withdrawn together laterally from the box and the chain wheel can likewise be withdrawn laterally via an aperture in the side of the box remote from the frame.

This mounting device is adapted to engage with a wheel spoke so as to maintain the pulley in a centered position relative to the wheel flange.

Abstract: Around an engine-body of a vehicle, several auxiliary machinery such as an air-conditioner and a power steering-pump are disposed. Pulleys of said auxiliary machinery are driven by means of an endless belt or endless belts by a driving pulley of the engine. In order to obtain the most effective operation of the engine, consideration should be given to the degree of the power loss for driving the auxiliary machinery.For this purpose, according to the present invention, the order by which said several driven pulleys are driven by said driving pulley is determined by the magnitude of the driven torques of the corresponding auxiliary machinery along the running direction of the endless belt toward the driving pulley.
