Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
An article for use in an ultrasonic injection nozzle for a liquid material, comprising vibrating element means adapted to be ultrasonically vibrated, said vibrating element means having a longitudinal axis, a first end adapted to be connected to a source of ultrasonic energy and a second end opposite said first end, said second end having a multi-stepped, edged portion having at least two steps, and liquid material supplying means for supplying liquid material to said edged portion to flow in a thin film at the edges of the edged portion, an edge of each step presenting an apex substantially tangential to the flow of said liquid material and being adapted to sever and atomize said liquid material as it flows over said edge.
Claim 2
Dependent Claim
123 words
