Abstract: A machine produces foam-in-bag from foam precursors mixed within the bag. The machine comprises a base and a shell. The base and shell are moveable relative each other between a base/shell disengaged position and a base/shell engaged position. In the base/shell engaged position, the base and shell divide the bag so that a mixing chamber is isolated from the remainder portion of the bag. First and second nozzles inject foam precursors into the mixing chamber. A mixer engages the mixing chamber to provide mixing energy to facilitate the foam reaction.

Abstract: A multi-chamber bag portion can be used as a package for a curable multi-component compound. The multi-chamber bag portion has at least two chambers separated from one another in liquid-tight manner, where one of the chambers is filled with a reactive component and at least one other chamber with a hardener component for the reactive component. The multi-chamber bag portion also has at least one separating element, which in storage condition separates the chambers from one another in liquid-tight manner and in ready-to-use condition provides fluidic communication between the chambers for mixing of the reactive component and the hardener component. An opening portion, which can be opened to discharge the mixed multi-component compound, is also a component of the multi-chamber bag portion.

Abstract: A propulsion device preferably includes a wing, a pair of sliding rails, an electric motor, an electrical power source, a pair of connecting rod supports and a pair of connecting rods. Each wing includes two lengthwise members, two cross rods, an outer layer and four roller bearings. Each sliding rail includes a lengthwise track formed on an inner surface thereof. Each end of a cross plate is attached to one of the pair of sliding rails. The electric motor is attached to the cross plate. The electrical power source is connected to the electric motor. The electrical power source is preferably secured to one of the pair of sliding rails. One end of connecting rod support is attached to one of the pair of sliding rails.

Abstract: The present invention provides a method for in-situ cleaning of walls of a reaction chamber, e.g. reactive ion etching chamber, to remove contamination, e.g. copper comprising contamination from the walls. The method comprises converting the contamination, e.g. copper comprising contamination into a halide compound, e.g. copper halide compound and exposing the halide compound, e.g. copper halide compound to a photon comprising ambient, thereby initiating formation of volatile halide products, e.g. volatile copper halide products. The method furthermore comprises removing the volatile halide products, e.g. volatile copper halide products from the reaction chamber to avoid saturation of the volatile halide products, e.g. volatile copper halide products in the reaction chamber in order to avoid re-deposition of the volatile halide products, e.g. volatile copper halide products to the walls of the reaction chamber.

Abstract: A reciprocating wind engine utilizing plural, movably mounted sets of panels to form pistons is disclosed. Cooperating first and second pistons may be spaced from each other on either side of a central crankshaft. As the wind strikes the surface of a first set of panels, the first piston is moved toward the crankshaft and the second piston is pulled toward the crankshaft from the opposite side. When both pistons are adjacent the crankshaft, the panels on the first or windward piston open to allow the wind to pass therethrough into contact with the panels of the second piston which are closed to present a uniform surface to the wind. The pistons are forced away from the crankshaft to complete one cycle of operation. The output from the crankshaft may be utilized to generate electricity, or for any other suitable purpose. Plural engine segments may be cooperatively joined together to form a bank of such units.
