Abstract: A guided surface waveguide probe structure is described. In one example, the guided surface waveguide probe structure includes a charge terminal elevated to a first height and a phasing coil elevated to a second height above a lossy conducting medium. The structure further includes a non-conductive support structure to support the phasing coil and the charge terminal. The non-conductive support structure includes a truss frame that supports the phasing coil at the second height above the lossy conducting medium and supports the charge terminal at the first height above the lossy conducting medium. The structure further includes a substructure bunker constructed in the lossy conducting medium. The substructure bunker can include foundational walls, a grounding grid formed in a foundational seal slab, and a covering support slab at a ground surface elevation of the lossy conducting medium, the covering support slab supporting the non-conductive support structure.

Abstract: A guided surface waveguide probe structure is described. In one example, the guided surface waveguide probe structure includes a charge terminal elevated to a first height above a lossy conducting medium and a phasing coil elevated to a second height above the lossy conducting medium, wherein the first height is larger than the second height. The structure further includes a non-conductive support structure to support the phasing coil and the charge terminal. The non-conductive support structure includes a truss frame secured to and supported over a substructure, and the truss frame supports the phasing coil at the second height above the lossy conducting medium. The non-conductive support structure also includes a charge terminal truss extension supported by the truss frame, and the charge terminal truss extension supports the charge terminal at the first height above the lossy conducting medium.

Abstract: A method of friction stir welding is provided. The method includes providing a stir tool configured to rotate about and move along a stir tool axis and includes a pin with a pin axial end surface and a pin tapered surface that extends radially outwardly from the pin axial end surface. The method further includes providing the first member with a first member faying surface and defining a normal line that is normal to the first member top surface, is perpendicular to a longitudinal axis, and extends through a reference point. The method further includes providing the second member with a second member faying surface and forming a joint interface between the first and second members. The method further comprises contacting the rotating pin with the second member faying surface, the stir tool axis being disposed at a side tilt angle upon contact.

Abstract: A seal having a wall or element contoured and of a predetermined shape as, for example, in the form of a right circular cylinder, an extension member and a curved sheet member joined to an extension member, with the curved sheet member along the element and curved about the element such that the curved sheet member is spaced from a surface to which the extension member is attached, such as a window sill, so that the curved sheet member is spaced from the surface and the element rolls and is compressed to seal the interface between the sash and the sill when the sash is closed against the sill with minimum abrasion of the seal.

Abstract: In accordance with the present invention, methods have been developed for the reduction of the chloride content of epoxy compound starting materials. Invention methods comprise fractionating an epoxy compound starting material into portions (e.g., fractions or cuts) having different chloride content relative to the epoxy compound starting material. Certain of these collected portions (i.e., the portions fractionated and collected after collection of the forecut and before discontinuation of the fractionation) contain substantially reduced chloride levels relative to the epoxy compound starting material.

Abstract: A water-based coloring composition suitable for use in children's markers comprising a carrier, submicron polymeric particles, and a neutral buoyancy additive. The coloring compositions produce unique opaque images on a wide variety of writing surfaces. Additionally, the invention includes a water-based dry erase coloring composition suitable for use in children's markers comprising a carrier, submicron polymeric particles, a neutral buoyancy additive, and a release agent.

Abstract: A steering shaft lock for heavy-duty trucks having a steering shaft and accessible universal joint. The steering shaft lock has an elongated member and a flexible member attached to one end of the elongated member. The elongated member is steel bar-like member and the flexible member is a link-chain type member having one or more apertures or links. The elongated member is adapted to engage a spaced defined in the universal joint and protrude therefrom. The flexible member is adapted to lockingly engage the outer perimeter of the elongated member (at the point of its protrusion) with a locking device, such as a padlock. The steering shaft is locked by moving the flexible member toward the protrusion of the elongated member and placing the shackle of a locking device through one aperture of the flexible member and over the outer perimeter of the elongated member.

Abstract: A washable dry erase coloring composition comprising an acid dye or polymeric dye colorant, a dye vehicle, a release agent, and an anionic dyeblocker. The dyeblocker additive may be an aromatic organic sulfonate and, preferably, is either a sulfonated naphthalene condensation product or a sulfonated phenol-formaldehyde condensation product. The dry erase coloring composition is suitable for use in marking on a whiteboard and enhances fugitivity from skin and fabrics. The dry erase coloring composition may optionally contain a film forming resin. More specifically, the invention is, in one preferred embodiment, a washable erasable whiteboard marker ink comprising an acid dye or polymeric dye, water, a film forming resin, a release agent and an aromatic organic sulfonate. In addition, the invention also includes a method of transferring an image from a whiteboard or non-porous surface to paper.

Abstract: A modeling dough comprising gelled poly(vinyl alcohol), water and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the poly(vinyl alcohol) resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. Prior to drying, the dough also exhibits the properties of bounceability and the ability to pick up newsprint. After the dough is air-dried, the poly resin serves to bind the components into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying. The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula. The dried product is sandable and paintable.

Abstract: A coloring system is provided in which an undercolor composition is applied to a substrate to thereby leave a colorless mark. The undercolor composition is then written over with an overcolor composition, thereby causing the undercolor mark to become colored. The overcolor composition may itself contain a colorant. In one embodiment, the color-changing effects are accomplished by employing a dye that is colorless in the presence of high pH and/or a reducing agent, but that becomes colored as the pH is lowered, as the undercolor colorant. In a second embodiment, the color-changing effects are accomplished by employing a dye that is colorless at low pH, but that becomes colored as the pH is raised, as the undercolor colorant.
