A directional air knife, components thereof, and associated methods. The air knife includes a housing that comprises an inlet opening which receives air under pressure into the housing along a first inlet axis. A chamber is defined within the housing and positioned to receive air that passes through the inlet opening along the first inlet axis. A discharge duct is defined by the housing and includes a discharge channel within the discharge duct. The discharge channel is in fluid communication with the chamber which receives the air under pressure. The housing defines an outlet opening through which the air under pressure passes out of the discharge duct. The discharge channel has a second central axis along which the air under pressure flows to the outlet opening and out of the housing. The second central axis is arranged with respect to the first inlet axis at a skew angle.

A method of forming aligned patterns on a mat contains steps of: (1). providing a main die configured to mold a body on a substrate; (2). forming multiple patterns on the body so as to produce a decoration portion; (3). forming a toothed cutting line on the body by ways of the alignment mark line so as to form multiple connection units on which multiple patterns are formed respectively, thus producing the mat; and (4). aligning the multiple patterns on the mat so as to provide or design the decoration portion on the multiple patterns, wherein the mat is disassembled to multiple coupling parts, and the multiple coupling parts of the mat are connected with another mat, thus producing an expandable mat.

A co-injection nozzle is disclosed that includes a combining means configured to reduce shear heating and create a more even shear heating profile in core and skin material flow streams. The combining means is configured to reduce shear heating peaks and valleys in core and skin material flow streams as the streams flow between annular channels of the combining means during a mold filling process.

A method for making a biocompatible three-dimensional heart valve includes delivering, using at least one delivery unit, a biocompatible fluid substance towards a mold having a mold surface to obtain a coating layer of predetermined thickness that coats the mold surface, where the biocompatible fluid substance includes a plurality of particles; handling the mold and the delivery unit to provide a relative movement with at least three degrees of freedom between the mold and the delivery unit, the mold coated with the biocompatible fluid substance that is delivered to obtain a three-dimensional heart valve having a surface corresponding to the mold surface; removing, using a suction and blowing device, from the mold any surplus particles of the biocompatible fluid substance dispensed to make uniform the predetermined thickness of the coating layer; and pressing a counter mold on the coating layer deposited on the mold after delivering the biocompatible fluid substance.
