Various embodiments of linear electric generators and arrangements thereof are disclosed. One such generator includes a permanent magnetic array with magnets that are oriented such that like poles of the magnets are disposed adjacently to concentrate a magnetic field through a coil array. To enhance the magnetic field distribution, the magnets are affixed under a compressive strain due to repulsive forces resulting from proximity of the like poles. According to another aspect, a plurality of vibrational linear electric generators (VLEGs) can be arranged so that magnets of different VLEGs are oriented so that poles of opposite polarity are disposed adjacently to further enhance magnetic field concentration through coil arrays. In addition, a plurality of wave energy converters can be arranged in very close proximity, at most 8 times a height of a buoyant portion of the converters, to act as a seawall and thereby protect various structures from ocean waves.

An unmanned air vehicle comprises a fuselage that defines aerodynamic flight surfaces, an engine mounted to the fuselage having an engine shaft arranged to rotate about a longitudinal axis with respect to the fuselage, and a propeller mounted to the engine shaft so as to rotate to thereby provide thrust. The aircraft also comprises a gyroscopic stabilization member coupled to the shaft such that rotation of the engine shaft results in rotation of the gyroscopic member. Thus, there is more stability during the entire flight envelope. In one embodiment, the gyroscopic stabilization member is comprised of a ring that is attached to the outer ends of the blades of the propeller and the ring is also selected so as to have a mass that will result in the gyroscopic stabilization member having a sufficient angular momentum so as to gyroscopically stabilize the aircraft.

An improved water generating device is provided for extracting water vapor from ambient air circulated therethrough. The device comprises an air pathway, a fan, a peltier module, a collection reservoir, and a heat sink. The air pathway defines first and second sections. A cold side of the peltier module is disposed in the first section and a hot side of the peltier module, whereto the heat sink is attached, is disposed in the second section of the peltier module. The fan draws the ambient air into the air pathway, and the cold side of the peltier module extracts water vapor out of the ambient air, which collects as water in the collection reservoir. The heat sink is partially disposable in the water and also includes a capillary tube which draws the water thereinto. Additional water vapor is extracted from the air, creating substantially dry air.

A beverage dispenser, for mating with a bottle containing liquid contents and having a top, a mouth at the top, a bottom, and an upper portion. The dispenser includes a base having side walls, a top, and cradle and intermediate plates extending horizontally through the side walls. A pipe has an inlet end centrally located above the intermediate plate and having internal threading for accommodating and securing to the mouth of the bottle, and an outlet end extending horizontally from the base and having a spout. The cradle plate has a central opening which is substantially concentric with the inlet end and supports the bottle at its upper portion. The beverage dispenser is inverted to fasten the mouth of the bottle to the inlet end, and then is turned ‘right-side-up’ to invert the bottle, and allow the contents of the bottle to be easily dispensed through the spout.

The reactor vessel of a nuclear reactor installation which is suspended from the cold leg nozzles in a reactor cavity is provided with a lower thermal insulating barrier spaced from the reactor vessel that has a hemispherical lower section that increases in volume from the center line of the reactor to the outer extent of the diameter of tiie thermal insulating barrier and smoothly transitions up the side walls of the vessel. The space between the thermal insulating harrier and the reactor vessel forms a chamber which can be flooded with cooling water through passive valving to directly cool the reactor vessel in the event of a severe accident. The passive inlet valve for the cooling water includes a buoyant door that is normally maintained sealed under its own weight and floats open when the cavity is Hooded. Passively opening steam vents are also provided.

At least one vertical strut supporting at least one sign has a lower end engaged within the at least one strut aperture, and further rigidly engaged with the receiver plate.

A hold down device used to hold down a tarp placed over an object or placed over a sloped surface. The device comprises a flexible elongated body capable of being rolled into a compact roll during storage and then unrolled for use. The body includes a bladder designed to be filled with fluid material, such as water or sand. Formed on the bladder is at least one port opening and a removable cap that allows the user to selectively fill the bladder with fluid material to provide weight used to hold-down the edge of the tarp. Located along the top edge of the body is a plurality of grommets. Extending through the grommets are adjustable clips that enable the body to be selectively attached to the lower edge of a tarp or stakes that allow the device to hold down a tarp placed over a sloped surface.

A drain cover assembly includes a closure device operable so as to close and open a drain hole in a cover plate of a drain cover unit. The closure device includes a pivot arm having a mounting portion connected pivotally to the cover plate, a flow control portion extending from and disposed on a first side of the mounting portion and registered with the drain hole, and a weighted portion extending from and disposed on a second side of the mounting portion and having a weight sufficient to overcome the weight of the flow control portion so as to cause the pivot arm to pivot from an open position to a normal closed position. The pivot arm pivots to the open position when the flow control portion is subjected to an applied load through the drain hole that is sufficient to overcome the weight of the weighted portion.

The instant invention provides a device for mounting, display, and storage of stringed instruments such as guitars. The device is comprised of a body having a generally U-shaped opening for accepting the neck portion of an instrument. The device provides a secure storage mount for a guitar or other similar instrument whereby the instrument can be secured in the device by merely placing the neck portion of the guitar into the U-shaped opening. The neck of the instrument provides a force that is substantially perpendicular with respect to the instrument neck to cause translation of a slider member. Movement of the slider member provides rotation to a pair of fingers to enclose the neck of the instrument with the U-shaped opening. In a more secure embodiment, an instrument can be locked into place using a locking mechanism that provides selective translation of the slider member. The device provides the capability of being mounted to surfaces as well as new or pre-existing free-standing instrument stands.
