    摘要: An interactive device includes a housing and a finger ladder held within the housing and having a number of parallel rungs. Each rung includes at least one sensor. A display system, which may include panels attached to either side of the ladder, produce sounds and/or images when the rungs of the ladder are contacted sequentially. Alternately, the display system may be integral with the finger ladder. The sounds and/or images may produce a song or a familiar sequence, such as the alphabet. The sequential activation of the sensors results in the development of both gross and fine motor skills, for example, in children, persons with developmental differences, and persons needing physical or occupational therapy.

    摘要: A process for modifying or repairing a metallic component, such as a combustion cap effusion plate for a gas turbine, is disclosed. The method includes generating a notch or groove in the metallic component and depositing a filler material in the notch or groove. A pulsed laser is applied to the filler material. The pulsed laser has a power, frequency, and pulse width sufficient to apply heat to the metallic component and to the filler material to make at least a portion of the metallic component and the filler material melt in order to weld the filler material to the metallic component and repair or modify the metallic component. Various operating parameters of the pulsed laser can be configured to reduce undesirable heating affects.

    摘要: A process and braze paste suitable for filling and closing voids in relatively thin wall sections of high temperature components, such as an impingement plate of a combustor of a gas turbine engine. The process entails applying at least a first braze paste to the crack to form a braze paste patch comprising powders of first and second alloys and an organic binder. The first alloy has a higher melting temperature than the second alloy, and the powders of the first and second alloys are present in the braze paste patch at a weight ratio of about 30:70 to about 70:30 weight percent. The braze paste patch is then heated to burn off the binder and melt at least the powder of the second alloy to form a brazement within the crack that contains particles of the first alloy dispersed in a matrix formed by the second alloy.
