Abstract: A golf club head having a slot in the sole filled with an insert in which the slot is positioned close to the striking face. The slot can be a uniform distance from the striking face or the slot can curve away from the striking face in the toe region. The insert can have a uniform height or a non-uniform height. Inserts with uniform heights can have a low height profile. Inserts with non-uniform heights can have a lower height in a central portion of the insert compared to an edge portion or a perimeter portion of the insert. The insert can also have flanges or protrusions for installation into the slot. The resulting golf club head improves performance, as the sole slot with insert allows the striking face to have a profile that meets the needs at that location.

Abstract: A ceiling material installation tool wherein the present invention assists in the installation of tongue and groove ceiling planks. The present invention includes a frame having an upper portion and a lower portion. The upper portion includes a lateral support member with longitudinal support members at opposing ends thereof. The lateral support member can be configured to be adjustable in length so as to place the longitudinal support members against adjacent support trusses that are alternate distances. The lower portion of the frame includes a vertical support member extending downward from the lateral support member. An upper horizontal member and a lower horizontal member are coupled to the vertical support member both being perpendicular to the vertical support member and axially aligned. The upper horizontal member can be vertically adjustable along the vertical support member so as to position a ceiling plank.

Abstract: Systems and methods are graphically developing rules for transforming models between different description notations. The transformation rules may be used to transform a model in a source description notation to a new model in a target description notation. In one embodiment, graphical constructs are provided including symbols in the source description notation and the target description notation. The constructs for the source description notation are arranged in a source pattern, and the constructs for the target description notation are arranged in a target pattern, according to user instructions. The source and target patterns are sent to a transformation engine and subsequently accessed to provide at least one transformation rule utilized by the transformation engine.

Abstract: The present invention provides a metal brightener and surface cleaner, which provides significant etching of aluminum and other metals, without detrimentally affecting other surfaces such as painted surfaces, glass, rubber and plastic. The inventive composition is especially suited for aluminum brightening for large vehicles, and may be utilized in an alkaline step of a multi-step vehicle wash. One of the exemplary compositions includes an alkali metal hydroxide; a polycarboxylic acid; an alkali metal salt of an organic acid; a first, amphoteric surfactant; a second, betaine surfactant; and a third, nonionic surfactant.
