Abstract: A low-cost, high-temperature heat exchanger is made from a notched piece of metal, the metal being folded back and forth upon itself to form a monolith. The notches in the metal piece create openings, communicating with distinct sides of the monolith. Ducts are attached to the openings. Cut pieces of corrugated metal, which may have a catalyst coating, are inserted between folds of the monolith. The heat exchanger may be used as part of a fuel cell system, or in other industrial applications, to recover waste heat, or to conduct various catalytic and non-catalytic reactions. The invention also includes an element, or building block, for a high-temperature heat exchanger, including a folded metal monolith with metal combs inserted, the monolith and the combs defining seams which are hermetically sealed.

Abstract: A laundry appliance having a cabinet enclosing a laundry treating mechanism, the cabinet having an openable door in a vertical front face thereof, is provided with a shelf recessed in the cabinet and arranged to be extendable to a horizontal position in an embodiment a predetermined distance below the door sufficient to allow a laundry basket to be placed on the shelf when extended and to allow the door to be opened and closed with the basket on the extended shelf and in an embodiment to provide a step for a user.

Abstract: An air duct for cooling rotating tires that broadly funnels or directs air up and into the face of an air fender or rotating tire. The air duct comprises a depending wall having an upper and a bottom edge. Formed within the wall is a leading tunnel section in communication with a baffle section, the tunnel section having a discharge end. The tunnel section defines at least one flow path which channel ambient air through the discharge end and into the baffle section where the air is subsequently directed into the face of air fender or rotating tire. The baffle section is defined as being between the discharge end of the tunnel section and the either the leading surfaces of an air fender or where there is no fender, the leading surfaces of the associated tire.

Abstract: A fender for a rotating tire. The fender has a leading section with parabolic shape vanes which control and discharge downwardly spray cast from the tire. A side shield is spaced apart from the upper half of the tire. The shield has specially dimensional louvers which ensure that the flow rate of the air therethrough is uniform as discharged from the shield to cool the tire and brake assembly.

Abstract: A fender to control water spray and to cool tires and brakes which has a leading plate with blade-like openings. The fender further comprises a top plate, a side wall and a trailing plate. The top plate with the leading plate form an air scoop. The side walls are louvered. The air is directed to expand adiabatically to both control the spray cast from the rotating tire and to cool the tires and brakes whether or not there is spray present.

Abstract: A stainless steel cylinder roller comprises a longitudinal groove formed in the cylinder. The groove has opposed edges extending from the outer surface of the cylinder inwardly with reference to the longitudinal axis of the cylinder. A weld covering is on the cylinder and extends into the groove and covers the edges. The depth of the weld on the edge being greater than the depth of the weld on the outer surface of the cylinder.

Abstract: A structure to control the spray cast from rotating wheels. A forward plate spaced apart from the leading edge of a wheel includes openings which directs the water spray rearwardly and inwardly with reference to the direction of travel of the vehicle. A trailing plate is spaced apart from the trailing edge of the rotating wheel. A baffle is secured to the leading and trailing plates and perpendicular to the axis of rotation of the wheel(s). This baffle includes openings to direct the spray inwardly.

Abstract: The invention broadly comprises forming a weld preparation groove in the surface of a cylindrical roller, said groove being parallel to the longtitudinal axis of the roller. The groove is filled with a weld material. Subsequently, the outer surface of the cylinder is welded with a compatible welding material to coat the cylinder surface. The weld materials both for the groove and the surface are compatible such that when the surface is welded, the weld material in the groove is recast to form a homogeneous grain structure with the surface weld. The slot is then formed and the surfaces of the facing walls of the slot, the slot edges and the roller surface are uniformly coated.

Abstract: A method for transporting particulates wherein the particulates are entrained in a transport air stream. An energizing air stream is introduced into the pipeline to form an air encasement stream between the inner wall of the pipeline and the transport air stream. The air encasement stream is introduced into the pipeline opposite directions to form a forward leaning movement of encasement air at a higher velocity than the transport air.

Abstract: Standard casing ends are formed for horizontally or vertically split casings. The casing end includes a variable dimensioned extension which is adapted to abut a shell section. The casing also includes a variable dimensioned stub end adapted to abut a nozzle. Once a shell thickness is determined, the extension is trimmed back to match the thickness of the shell section. The stub end is trimmed back and its inner diameter is enlarged, if necessary, to match the dimensions of a selected nozzle.

Abstract: A composite horizontally split casing includes an inlet end having upper and lower cast inlet end sections, an outlet end having upper and lower cast outlet end sections, and separable upper and lower semi-cylindrical shell sections extending axially between the inlet and outlet ends. The upper semi-cylindrical shell section is welded at opposite ends respectively to the upper inlet and outlet end sections to form an upper casing half. The lower semi-cylindrical shell section is likewise welded at opposite ends respectively to the lower inlet and outlet end sections to form a lower casing half. External bolting flanges on the upper and lower casing halves provide the means by which the upper casing half is mounted on the lower casing half.
