Abstract: Metal laminate cores can be assembled with laser pin welding through a thickness of a first laminate into a second laminate and successively laser pin welding a plurality of second laminates, ending with a third laminate to form the core stack. The laser pin welds are located within an outer perimeter of one or more of the laminates. Such laminated cores are often utilized in electrical motors, generators, transformers, lighting and other applications. The laser pin welds can be selectively provided under the control of a processor to index about the parts and/or change in intensity or even skip certain parts so as to be able to begin and end cores for some embodiments while also facilitating manual and/or automated stacking/welding embodiments and/or relative rotation of the cores.

Abstract: A device with a handle, for securing a sponge, mesh sponge or other medium with a string or cord attached, and used for the purpose of bathing, massaging or applying a substance to ones body and more precisely to ones back or other hard to reach areas of the body. An improved back and/or body scrubber which holds a common mesh sponge or similar item, and allows for its quick installation and removal. The invention is comprised of a handle (7), which acts as a housing to contain plug (2), spring (3), finger pilot (4), finger (5), and pusher (6). Along with cap (9), these components work together as a spring-loaded unit for the purpose of pulling and holding a mesh sponge, or similar item, by its string or cord, into head (1) through a slot in the side of head (1). The purpose of the bell or cone shaped head (1) is to gather and push forward the folds or surfaces, of a mesh sponge or similar item, creating a wide and stable surface suitable for scrubbing or washing ones body.
