The invention provides a novel jackhammer that utilizes ultrasonic and/or sonic vibrations as source of power. It is easy to operate and does not require extensive training, requiring substantially less physical capabilities from the user and thereby increasing the pool of potential operators. An important safety benefit is that it does not fracture resilient or compliant materials such as cable channels and conduits, tubing, plumbing, cabling and other embedded fixtures that may be encountered along the impact path. While the ultrasonic/sonic jackhammer of the invention is able to cut concrete and asphalt, it generates little back-propagated shocks or vibrations onto the mounting fixture, and can be operated from an automatic platform or robotic system.

Ultrasonic/sonic jackhammer

A fabricated food product is prepared by shaping a blend of edible textured protein particles, including single cell protein, bound together with a whey protein concentrate composition having more than 30% protein which is capable of forming a gel at 15% solids within 30 minutes when heated at 85.degree. C., wherein at least 50% of the protein in the whey protein concentrate is whey protein prepared by physical separation techniques.
