Abstract: The present subject matter relates generally to an apparatus for crumpling paper substrates. Specifically, the system provides for the crumpling of paper substrates to form fill material to be utilized in product packaging to fill void space and/or to wrap around products thereby allowing for safe transport of the products. The apparatus includes a feeder for feeding sheeting material, a first roller connected to a drive mechanism, a second roller disposed adjacent said first roller wherein said sheeting material travels between the first roller and the second roller and further wherein the second roller pushes said sheeting material against said first roller to engage the sheeting material with the first roller, and a third roller connected to the drive mechanism for directing said sheeting material out of said apparatus.

Abstract: The present subject matter relates generally to a system and a method for crumpling paper substrates. Specifically, the system and method provide for the crumpling of paper substrates to form fill material to be utilized in product packaging to fill void space and/or to wrap around products thereby allowing for safe transport of the products. The system comprises, generally, a paper crumpling machine having a braking mechanism for preventing uncontrolled rolling of a paper roll, a rake for effectively guiding paper sheeting into the paper crumpling machine, and a disengagement mechanism for easily disengaging the paper sheeting from the apparatus if necessary, and an automatic tensioning device for providing even distribution of tension on the paper sheeting. In addition, the apparatus comprises a cutting mechanism and/or a clamping mechanism for allowing cutting and/or clamping of the crumpled paper substrate.

Abstract: Apparatus and methods are provided for automated movement of an umbrella. An apparatus can be manually or automatically actuated to move the umbrella so as to provide more or less shade as desired by the user. For example, an apparatus is provided which can automatically move an umbrella to follow the movement of the sun. The apparatus can provide maximum or minimum shade (as desired) to the user throughout the day and/or can change the angle of the umbrella with little or no effort by the user. An adjustable umbrella apparatus comprising a ballast-shifting means is also provided.

Abstract: A biaxial driver includes an induction coil that is moveable in two dimensions and a linearly oriented magnet. A payload platform for holding a tool or workpiece is attached to the moveable coil. The inventive driver provides motion parallel to an axis of the magnet, even while the coil is moved transversely or obliquely to the axis of the coil, and permits the degree of coil extension to be varied while the biaxial driver is operated. Because the magnet is held stationary during movement of the payload platform, there is no inertia from the stationary magnet to overcome. A result, the payload platform can be moved from one position to another in less time, the payload platform can carry a more massive payload than previous positioning drivers and the invention requires less energy consumption.

Abstract: A method of detecting combustor dynamic pressures in combustors of a gas turbine combustor includes the steps of: a) mounting at least one accelerometer (24) on a combustor casing; b) establishing a baseline vibration signature for the casing when combustion dynamics are minimal; and c) measuring subsequent vibration signatures and comparing those signatures to the baseline signature.

Abstract: A general purpose valve is provided to control the discharge of particulate material. An overlying plate with a first, through aperture, cooperates with an underlying plate having a solid surface and a second through aperture. The first aperture is in vertical alignment with the solid surface on the underlying plate. Structure is provided to vary the vertical spacing between the overlying and underlying plates to selectively commence, terminate, and vary the rate of flow of particulate material.
