Abstract: A system of making self-aligning concrete block structures. Structure is made of interlinking blocks that have insulative foam that is affixed during the molding process. The interior surface of the blocks is specifically designed to avoid the use of interior framing by providing wooden strips such that drywall can be directly affixed. The concrete block system include top blocks, inside and outside corner blocks, and the necessary forms for their construction.

Abstract: A vacuum lifting device and method of manufacture thereof includes a vacuum generator for generating a vacuum. The vacuum lifting device also includes a base having opposite first and second sides and a vacuum lifting chamber provided on the second side of the base and having a suction end. The vacuum lifting chamber is in fluid communication with the vacuum generator, wherein the vacuum generator creates negative pressure within the vacuum lifting chamber. A gasket is coupled to the suction end of the vacuum lifting chamber and is configured to create a vacuum seal with a surface of an object to be lifted by the vacuum lifting device.
