Abstract: A bonded mesh composite panel of an upper includes a substrate layer formed from a substrate material, a mesh material layer and one or more skin material layers. The mesh composite can be fabricated by first arranging panels of substrate, mesh and skin layer material into an assembly corresponding to the locations of those panels in a completed upper. The assembly may include separate layers of hot melt bonding material interposed between the substrate, mesh and skin layers. The assembly is pressed at an elevated temperature so as to melt the bonding material and the skin layers and bond the elements together. Before the pressed assembly completely cools, it is then pressed a second time in an unheated press. A heat-conductive compressible pad can be used in the pressing process to create a surface effect in the skin layers that reveals a patterns of an underlying mesh layer.

Abstract: What has been developed is a keyless door lock that prevents young children from opening doors their parents or caretakers do not wish them to open. The lock is a bolting mechanism type lock or a latching type lock having no keyed lock access side to it, but rather, a means for locking and unlocking the lock, such as a knob, on one or both sides of the door that when turned, unlocks the door. The lock is positioned within the door at a height that is unreachable by small children. The lock is useful for locking doors internal to the home (e.g., doors to medicine closets, cleaning supply closets, garage doors, doors at the top of stairs) as well as doors that provide access to the exterior of the home and therefore access to leave the premises of the home without supervision. Adults and older children, however, are never locked in or out of the room or house as no key is required for operating the lock, merely the turning of a knob.

Abstract: Abrasive material such as diamonds are transported onto a ferromagnetic tool blank from a suspension of brazing flux and diamonds coated with ferromagnetic material. The tool blank is prepared by coating a receptor site with brazing alloy. A magnetic field is applied to the tool blank, and the coated receptor site is placed in contact with the suspension. The receptor site is heated to brazing temperatures to liquefy the coating, allowing diamonds from the suspension to be transported by magnetism to load the liquefied brazing alloy, forming a matrix at the receptor site.
