Abstract: A tuned mass damper (TMD) system in combination with a floating offshore wind turbine (FOWT) platform includes a barge type FOWT platform having a hull configured to have a wind turbine tower mounted thereon. A TMD system is mounted in the hull and has a first TMD configured to operate at a first frequency, and a second TMD configured to operate at a second frequency different than the first frequency.

Abstract: The present disclosure relates generally to methods for preparing a graft with at least two implants of biocompatible materials, the graft being folded a plurality of times prior to being used in reconstructing a treatment site. Methods of this disclosure are contemplated for preparing a graft at a site outside of a hospital setting, storing offsite, and/or later transporting to the hospital for use with a patient.

Abstract: A method and apparatus facilitate the efficient, safe use of storage space in a building structure. The apparatus stores hand tools of differing shape and dimension in a compact area in nested, canted storage units shaped to receive the handles of tools.

Abstract: Food dispensing apparatus minimizes the likelihood that food particles dispensed into an aquarium will contaminate the water filtration system or will stick to the sides of the aquarium. The food dispensing system suspends a hollow food dispensing member in water in the aquarium such that the food dispensing member guides food to the bottom of the aquarium free from being transported by prevailing currents in the aquarium.

Abstract: A stand stores long-handled garden tools. The tools are removed from the stand to be used. The stand is unusually compact and permits a plurality of garden tools to be stored in close proximity to one another. The distal end of a garden tool is slidably received by a sleeve formed in the stand. The sleeve is shaped to contact the distal end of the tool and maintain the tool in a substantially vertical orientation while permitting the tool to generate a force which forces the stand against the ground.

Abstract: A method is provided for mailing a package to confirm to a recipient that the package is safe to open. The method includes the step of providing an envelope including a plurality of folded edges; including perforations formed along at least one of the folded edges; including a plurality of fold traps formed along the folded edge, each fold trap being adjacent at least one of the perforations; and, including a mouth. The method also includes the steps of placing contents in the envelope; closing the mouth of the envelope; addressing the envelope to the recipient; applying postage to the envelope; mailing the envelope to the recipient; and, inspecting, on receipt of the envelope by the recipient, the envelope to determine if at least one of the folded edges includes perforations and fold traps. The presence of the perforations and fold traps indicates that the envelope is safe to open.

Abstract: A method and apparatus for assembling a drip irrigation system includes a drip irrigation member with a connector and includes a length of tubing. The tubing has an end. A securing member is mounted on the end of the tubing. The end is slidably forced over the connector. The securing member is rolled along the tubing to a position at which the securing member elastically circumferentially compresses the tubing against the connector.

Abstract: An inlet hose feeds a tank that may be placed in a household sink which is too high above a floor for a conventional wet vacuum to lift a column of water. One or more inlet hoses each have a water pickup tube at the distal end. The hoses are connected to the tank chamber which has a vacuum created by a vacuum cleaner apparatus. An air inlet aperture in the pickup tube at the distal end of the inlet hose is kept above the water level. An air stream is drawn into the aperture of the pickup tube by the vacuum, which causes turbulence in the water stream in the pick up tube and breaks the water into droplets. This enables the vacuum of a given magnitude to lift the droplets to a higher elevation than a solid water column. Air inlet and water discharge valves are provided on the tank to control the water fill rate into the tank. An interior hose or channel stops the vacuum to the pickup hose when the fluid in the tank gets too high. A window in the tank permits observation of the fill rate.

Abstract: A combustion powered tool having a self-contained internal combustion power source constructed and arranged for creating a combustion for driving a driver blade to impact a fastener and drive it into a workpiece includes a housing having a main chamber enclosing the power source, a combustion chamber defined within the main chamber, an air flow enhancing device disposed in the combustion chamber for enhancing the flow of air therein, and a supplemental air flow enhancing device disposed externally of the combustion chamber and within the housing for forcing air past the combustion chamber as a cooling mechanism.

Abstract: In a fastener-driving tool comprising a housing structure defining an axis and a nosepiece extending from the housing structure, a primary actuating structure is movable between a tool-disabling position and a tool-enabling position, and a secondary actuating structure is coactive with the primary actuating structure for moving the primary actuating structure to the tool-enabling position when the secondary actuating structure is pressed firmly against a workpiece. The primary actuating structure is biased to the tool-disabling position by a primary spring or springs. The secondary actuating structure is biased away from the primary actuating structure by secondary springs. When the secondary actuating structure is pressed firmly against a workpiece, the primary spring or springs exhibit a biasing force less than the biasing force exhibited by the secondary springs. The secondary actuating structure may also be biased away from the housing structure by a tertiary spring.

Abstract: A wet cell battery monitor developed to monitor both electrolyte fluid level and electrolyte fluid charge (specific gravity) of a single cell. The monitor includes a probe and appropriate circuitry. The probe is adapted for insertion into a cell for monitoring and is connected to two circuits which are interconnected. Both include resistors, preferably variable, and include induction coil type relay switches. Blocking diodes are preferably used to maintain the independent integrity of each of the two circuit, one which warns of fluid level drop off and the other of a decrease in electrolyte fluid charge. The two circuits each drop off independenly in response to specific gravity (state of charge) and to fluid level, respectively, setting off alarms, e.g. visual or audio signals.
