Abstract: A method and apparatus for stacking newspapers is disclosed which obviates the need to fasten individual stacks. Once ejected from a stacking device, stacks of newspapers pass through an assembly station where they are arranged into groups of three, called slugs, and compressed. The slug then enters a collector where a layer consisting of four slugs is positioned on a sliding table. This positioning requires lateral movement of slugs. Lateral support is provided throughout this movement to prevent the stacks from toppling over. Once a full layer has been accumulated, the sliding table is retracted, and the layer of newspapers falls onto a floating table below. This floating table, which serves as the bottom floor of the container in which it is housed, is automatically lowered by discrete amounts as layers are received. Extendible cylinders located below the collector vertically move the floating table.

Abstract: In a gas-generating chemical reaction carried out in a borehole that is largely filled with water, substantial pressure increases can be generated. This pressure can be used to fracture rocks around the borehole and, hence, stimulate water, oil or gas wells in tight rock formations. This pressure increase can also be used to fracture coal seams for enhanced in-situ gasification or methane recovery. This invention discloses the use of a new, novel system, based on the homogeneous reaction of aluminum alkyls with water, to create a controlled pressure increase. The most appropriate reaction mixture, as characterized by the rise of time of the generated pressure pulse and the energy content per unit length of borehole charge, is disclosed in this new invention.
