Self-supporting structures having active materials
A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

METHOD OF AND APPARATUS USING A SPLIT WIPER FOR THE REPAIR OF OBJECTS PROTRUDING ABOVE A POWDER BED
A method of repairing a component using an additive manufacturing process is presented. The method includes submerging the component into a powder bed so that a portion of the component to be repaired is level with a surface of the powder bed and a protruding portion of the component protrudes above the surface of the powder bed, positioning a split wiper that includes a first wiper segment and a second wiper segment in the powder bed at the surface, advancing a quantity of powder by translating the first wiper segment and the second wiper segment across the surface of the powder bed, and directing a laser beam across the surface to fuse powder particles of the powder bed to the underlying substrate forming a layer of the component. Each of the first wiper segment and the second wiper segment follow a different contour of the protruding portion at the surface.
METHOD FOR MAKING HIGH LUBRICITY ABRADABLE MATERIAL AND ABRADABLE COATING
An abradable powder composition is includes a metal component, a lubricant component, and a polymer component. A portion of the metal component is wrapped in the lubricant component to achieve high lubricity and abradability. The abradable powder composition can be used to form an abradable seal coating provided for use in a turbo machinery having a housing and a wheel having multiple blades. The housing houses the wheel which rotates therein. The seal coating is formed on the inner walls of housing adjacent where the wheel blades pass during their rotation. When the wheel is rotated such that, the blades contact the seal coating, it is abraded to form a close fit gap. The abradable seal coating preferably does not produce significant wear of the blade tips or transfer abradable material significantly to the blade tips upon being abraded.

BURNER ELEMENT FABRICATION USING INJECTION MOULDING AND CONSEQUENT SINTERING
A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.
