The invention relates to a method of making a paper product 10, 10.01 to 10.14, wherein the method includes the step of adding natural reinforcing material (31, 31.1, 51, 51.1, 61, 61.1, 71, 71.1) to one of: a) a layer of pulp as it exits or after it exits from a layer formation process or apparatus; or b) a tank 20, 20.1, 20.2 of pulp prior to it exiting from a layer formation process or apparatus; or c) a combination of a) and b). Additionally, the invention relates to paper products made by this process. The present invention also provides a multi-layered material 2.10, 2.10″, 2.10.1, 2.100 to 2.1600, and 100 to 1900, and a layer treatment of a layer or layers of a multilayered material, and a multilayered material which has had such a layer or layers treated by such a layer treatment.

A form for forming a void or an architectural feature of a predetermined configuration in a moldable forming composition is disclosed. Embodiments of the invention provide an adjustable form body having first and second sides, said form body configurable between a first substantially planar position and a second non-planar position. In some embodiments, the form comprises a surface coating. A form body according to example embodiments of the invention has a plurality of grooves.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

A multi-axially braided reinforcement sleeve that provides a low cost, simpler method to form strong concrete columns for constructing buildings and other structures. The braided reinforcement sleeve provides structural support and the rebar normally embedded to provide structural support in concrete can be eliminated, preventing the possibility of rebar oxidation which might otherwise undermine the structural integrity of the column. The reinforcement sleeve is lightweight, easy to transport, and can be greatly reduced in size to facilitate transportation. The reinforcement sleeve and construction method can be utilized in many implementations, and can be particularly useful for constructing buildings or other structures in geographic areas that are subject to earthquakes and where low cost is important.

A system of reusable components and articles of manufacture for reconstructing, reinforcing, and/or repairing a structure such as columns, piles and the like using adjustable formworks. The reusable articles of manufacture employed in the disclosed system are or, if desired, may be permanently left in place. Same or similar systems and articles of manufacture may be employed to easily construct pipes of any desired diameter in a very short time.
