Abstract: A piston ring that is pre-treated by grit blasting to a defined roughness, followed by PVD coating with a metal nitride to a thickness of at least 10 ?m, leaving peaks and valleys in the coated piston ring. The coated piston ring is then lapped to remove the peaks without penetrating the coating, so that valleys and plateaus remain in the coated surface. The resulting piston ring exhibits superior coating retention due to the increased surface area created by the grit blasting, and yet also superior performance, as the cavities remaining increase the porosity of the coating and thus enhance the lubrication of the ring.

Abstract: A ring carrier for a piston for an internal combustion engine is formed by a carrier body having an outer circumferential surface, an inner circumferential surface, a top surface and a bottom surface, with at least one ring groove formed in the outer circumferential surface. An outer circumferential portion of the ring carrier is formed of gray iron, and an inner circumferential portion is formed of ductile iron. A transition region between the outer circumferential portion and the inner circumferential portion intersects upper and lower flanks of the ring groove, so that an outer circumferential extent of the flanks is formed of gray iron and an inner circumferential extent of the flanks is formed of ductile iron.

Abstract: A drug delivery device with removable pods is described and related pods methods and systems. The drug delivery device comprises a plurality of receptacles, each receptacle configured to accept a corresponding drug pod, wherein each receptacle comprises: a recess configured to accept a protrusion in the corresponding drug pod, or a protrusion configured to insert in a recess in the corresponding drug pod. The corresponding drug pod comprises a shell, made of an impermeable polymer, having a first base comprising an opening configured to allow delivery of a drug, a second base, a lateral surface, a protrusion attached to, and extending away from, the lateral surface, or a recess in the lateral surface.

Abstract: The present invention provides for a drug delivery device. The device can comprise at least one core with a first active pharmaceutical ingredient (API), coated with a first layer that is permeable or semi-permeable to the API, coated with a second layer that is impermeable to the API and having a delivery window to allow passage of the API through the device and into body fluids or tissues. The device can also have a wicking material to modify the rate of transport of the API into the body fluid or tissues.

Abstract: A method of forming a piston ring includes providing a base portion formed of a metallic material, the base portion having a first surface, and a second surface that is opposite the first surface, the base portion configured to interface with a piston ring groove. The method includes grinding the first surface to form a reference surface, applying a chromium layer to the second surface, and grinding the chromium layer to reduce a surface roughness of the chromium layer.

Abstract: Exemplary oil control rings and methods are disclosed. An oil control ring may include an upper lamella having a first outer radial surface and a lower lamella having a second outer radial surface. An expander ring is in communication with the upper lamella and the lower lamella and generates an expander radial outward force on the lamellas. At least one of the first outer radial surface and the second outer radial surface is comprised of a first contact section and a first tapered section. The first tapered section is configured to generate a first radially inward force greater than or equal to the expander radial outward force when moved in a first direction and a second radially inward force less than the expander radial outward force when moved in a second direction.
