A paw is the soft foot of a mammal, generally a quadruped, that has claws or nails. A hard foot is called a hoof. Paws are used to pad feet for walking and reduce friction.
Paw is a widgetset for generating a GUI on ASCII based terminals. It contains button, radiobutton, label, line, listbox, text_entry, pull-down-menu, filedialog, popup-box and more. Examples are included. This software requires Perl::Curses.
Power Adjust Wheels. Rims that would allow spacing to be adjusted laterally without removal or jacking. Allis Chalmers brought out a rim style in the early 50s with spiral bars that would allow this movement by simply loosening the lock bolts and releasing the clutch while the opposite brake was on. Thus the power of the engine would pull or push the rim in or out. This became common on all machines until the size requirements of upper-end tractors and the shift to chemical-based "cultivating" made spacing adjustments somewhat moot. This capability is still extremely viable and appreciated where manual cultivating is practiced.
Plasma Arc Welding. Specialized process utilizing a non-consumable electrode ionizing an inert gas and increasing temperature to melt the material being welded.
