Abstract: A Baseball Training Bat is provided and includes a bat first end, a bat second end, and a bat middle portion having a bat handle portion, wherein the bat middle portion connects the bat first end with the bat second end, and wherein the bat handle portion includes a grip collar, wherein the grip collar includes a first collar end separated from a second collar end via a collar center, wherein the first collar end includes a first collar end diameter, the second collar end includes a second collar end diameter and the collar center includes a collar center diameter, wherein the collar center diameter is larger than the first collar end diameter and the second collar end diameter.

Abstract: An ultrasonic sealing device, including a horn having a sealing surface, an anvil having a sealing surface, at least one of the horn and the anvil being moveable to engage the respective sealing surfaces, the sealing surfaces of the horn and the anvil including a plurality of protrusions and a recess between each of the protrusions, each of the protrusions having a flat distal surface and sloped sidewalls with curved edges therebetween and each of the recesses including a flat recess surface with curved edges, wherein, upon engagement of the sealing surface of the horn with the sealing surface of the anvil, the flat distal surfaces of each of the protrusions on each of the sealing surfaces engage corresponding ones of the flat recess surfaces of each of the recesses on each of the sealing surfaces and define gaps between the sloped sidewalls of each adjacent protrusion.

Abstract: An ultrasonic tool having a sonotrode having a single weld region and two nodal regions formed on either side of the weld region. Two rigid mount boosters are each coupled to either side of the weld region. One transducer is coupled to one of the rigid mount boosters. Two ultrasonic stack mounting rings are each configured to be coupled to a housing assembly at a non-nodal region and coupled to one of the rigid mount boosters at a nodal region.
