A patch system and methods for using a patch system are described herein. The patch system has an elastomeric central portion configured to expand and contract over the types of distances commonly found in homes and other buildings that can result in opening and closing cracks in walls, for example. By applying the patch system across a crack under pre-tensioned conditions, opening and closing of the crack will not cause a visible defect in the wall or other surface.

The invention to provide a system of equipment for making synthetic building materials using plastic wastes combined with industrial and agricultural scrap includes: sorting and cleaning equipment, grinding equipment, powder grinding equipment, mixing equipment, pelletizing equipment, drying equipment, hot stir equipment, shaping equipment are connected together by mechanical connectors. The database connected to the controller controls the sorting and cleaning equipment, the grinding equipment, the powder grinding equipment, the mixing equipment, the pelletizing equipment, the drying equipment, the hot stir equipment, and the shaping equipment through transmission channels. In addition, the present invention provides a method of manufacturing for making synthetic building materials using plastic wastes combined with industrial and agricultural scrap.

A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture.

A method of manufacturing composite laminate panel sub-elements (34) for subsequent assembling into a modular assembly structure (37), comprises the preprocessing steps of casting an elongate composite laminate sheet panel (18) having opposite first and second fiber-reinforced plastic face skins (19,21) sandwiching a core (35), a free first elongate edge (22) and an opposite second elongate free edge (24), demolding the elongate composite laminate sheet panel (18), cutting the demolded elongate composite laminate sheet panel (18) into (n) shorter sections (Sn), thereby providing sections (Sn) with at least one free cut edge (26; 32), a free first edge (22) having the same profile as the free first elongate edge, and a free second edge (22) parallel to the free first edge and having the same profile as the free second elongate edge, and machining at least a first coupling profile (27) along the at least one free cut edge (26; 32).

The present invention relates to a method of making a composite sandwich structure. The method comprises the steps of: providing a base lay-up on a surface, wherein the base lay-up comprises a first reinforcement material layer; providing a core layer on to the base lay-up, wherein the core layer comprises an open cellular structure and wherein the open cellular structure is at least partially filled with unbound particles; providing a top lay-up on top of the core layer, wherein the top lay-up comprises a second reinforcement material layer; sealing the arrangement within a hermetically sealed enclosure; introducing matrix material into the arrangement via the at least one conduit through a pressure differential; and curing the matrix material.

Methods for manufacturing foam wall structures are described. The methods include placing a wall structure proximate to a robotic arm, orienting an imaging device so that the imaging device on the robotic arm faces a cavity in the wall structure, surveying the cavity using the imaging device, determining a spray foaming pattern to fill the cavity to a selected depth with a foam layer, orienting the spray nozzle so the spray nozzle faces the cavity, and spray-applying the foam-forming composition into the cavity to the selected depth by passing the foam-forming composition through the spray nozzle to form the foam layer. Foam wall structure manufacturing systems that are suitable for carrying out such methods are also described.

The present application relates to a product made with food processing by-products/wastes in particular from the cocoa and chocolate industry, the coffee roasting industry, the wine and distillery industries, the beer industry, the olive oil industry and the fruits and vegetables industries, mixed with a binder, preferably a bio-based binder. The present application also relates to the method of manufacturing the product.

In one embodiment, a multiwall sheet can comprise: a first wall; a second wall; an intermediate wall disposed between the first wall and the second wall; a first set of ribs disposed between the first wall and the intermediate wall; a second set of ribs disposed between the second wall and the intermediate wall; a cavity disposed between adjacent ribs; wherein the multiwall sheet is configured to expand and/or collapse when a mechanical force (preferably shear force) is applied to the intermediate wall. Preferably the multiwall sheet has a flexural rigidity of greater than or equal to 10 N/mm.
