Abstract: In one embodiment, the invention is a method comprising contacting a composition comprising i) alumina particles having a particle size of about 1 to about 40 microns and a Mohs hardness of about 9.0 to about 9.5; ii) one or more alkyl sulphates; iii) one or more thickeners; and iv) water with the surface of glass or a ceramic frit disposed on the surface of glass. The contacting can be performed by applying the composition to the surface of the glass or the ceramic frit using an application apparatus. In one embodiment, the composition further comprises a lubricant. In another embodiment, the composition further comprises one or more ethoxylated alcohols. In another embodiment, the composition further comprises one or more fragrances.

Abstract: An improved apparatus and method of joining two metallic components prior to making a full seam weld is disclosed. A first inner structural metallic component has at least one neutral zone, an inner surface, an outer surface and an aperture located in the neutral zone. A second outer structural metallic component has at least one neutral zone, an inner surface, an outer surface and a dimple with a raised portion on the inner surface and a recessed portion on the outer surface. The method uses the steps of joining the first and second metallic components so that the first component outer surface and the second component inner surface are directly adjacent each other, and joining the two structural metallic components by forming a full seam weld between the two components.

Abstract: Method and apparatus for providing a turbofan blade 40 adapted to initiate and control a boundary layer transition at a side surface of the blade 40 during operation as a component in a turbofan assembly 35. The turbofan blade 40 includes a leading edge 55, a trailing edge 58, and two side surfaces including a high-pressure side surface 49 and a low-pressure side surface 52. At least one of the two side surfaces has an essentially smooth surface portion 61 located between the leading and trailing edges, and the essentially smooth surface portion is interrupted by a surface deviation 64. The surface deviation is configured to fix a positionally unstable laminar to turbulent boundary layer transition 24 at a location toward the trailing edge from the surface deviation during operation of the turbofan blade in the turbofan assembly.

Abstract: A die assembly for forming a workpiece includes a support clamp, a first clamp that is movable relative to the support clamp to engage a first portion of the workpiece, and a second clamp that is movable relative to the support clamp to engage a second portion of the workpiece. A forming punch is movable relative to the support clamp after the first clamp and the second clamp have been moved to form the workpiece.

Abstract: A book rack and pencil tray combination has a book rack and a pencil case attached to the bottom wall of the book rack. The pencil case is optionally attached to the bottom wall of the book rack by a pencil case attachment plate attached to the bottom wall of the pencil case. The pencil case attachment plate is typically attached to the bottom wall of the pencil case such that a portion of the bottom wall of the book rack is sandwiched between the pencil case attachment plate and the bottom wall of the pencil case.
