Abstract: The present invention is directed to a quilting tool and method for preparing unique quilt blocks. Advantageously, the inventive quilting tool includes a template with a fabric-marking window. In a preferred embodiment, the quilting tool includes the template, and an insert with a fabric-marking window. Beneficially, layout of fabric windows in multiple fabric pieces is uniform, and there is provided a wide variety of fabric window shapes and sizes useful for applique and reverse applique patterns. In a preferred embodiment, the quilting tool allows a quilt maker to make a unique wheel-and-spokes pattern.

Abstract: A rotor blade assembly for a wind turbine includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge. A vortex generator accessory is mounted to either of the suction side or pressure side and includes a base portion and a protrusion member extending upwardly from the base portion. An attachment layer connects the base portion to the suction or pressure side. The attachment layer has a lower shear modulus than the base portion to allow for shear slippage between the base portion and the underlying suction or pressure side.

Abstract: A garment marking machine includes a lower marker-supporting track supported by a base plate, and a garment-supporting plate positioned and supported above the lower track. An upper marker-supporting track is positioned above the garment-supporting plate by means of posts that extend upwardly from the base plate and through the lower track and the garment-supporting plate. Marker assemblies positioned along the upper and lower marker tracks are used to mark garments processed by the garment marking machine. A marker assembly utilized in the garment marking machine includes a marker cap having a bore, a marker having a marking end disposed through the bore of the marker cap such that only a portion of the marker extends beyond the marker cap, and an adjusting rod operative to move the marking end of the marker through the bore of the marker cap. The bore of the marker cap is sized to tightly hold the marking end of the marker.

Abstract: A machine for marking a garment for placement of subsequent operations, such as buttons and buttonholes, includes a frame, a first garment marking plate mounted on the frame and carrying a plurality of first garment marking media, and a second garment marking plate mounted on said frame and carrying a plurality of second garment marking media. Drive means arcuately move the first marking plate relative to the second marking plate between a ready position wherein the first and second marking media are spaced from each other and from the garment and a marking position wherein said first and second marking means are in close proximity to each other and in simultaneous contact with the garment to mark the garment.

Abstract: A marking light, or an attaching-position indicator, for a buttoning apparatus to indicate the position where each button member is to be attached in place, comprises a slender optical pointer member, engaging means secured to the rear end of the optical pointer member for selective engagement with a part of a pusher of the buttoning apparatus, a fixing member for the indicator including a support having means to support the front end portion of the pointer member so as to be movable back and forth with respect to a position immediately below an upper attaching die of the apparatus, release means connected to the engaging means for disengaging the engaging means from a part of the pusher, and means for biasing the pointer member in the direction of withdrawal clear of the upper attaching die. The support is equipped with a resilient engaging means fixed at one end to the fixing member and so disposed as to engage resiliently a part of the support at the other end.
