A multi-purpose tool powered by an attached power source is used as an air blower capable of delivering a high-velocity stream of air when the multi-purpose tool is in a blower mode of operation and as a rotating string trimmer capable of trimming vegetation when in a trimmer mode of operation. The tool includes a tubular shaft boom and an internal drive shaft configured to be rotated by the power source, and an impeller operatively connected to the internal drive shaft so as to be rotatable within the chamber and a trimmer head positioned below the impeller, the trimmer head operatively connected to the internal drive shaft so as to be selectively rotatable by the power source. The tool also has a blower housing positioned at a distal end of the shaft boom including an enclosed chamber, a plurality of vents leading to the chamber, and a blower nozzle for directing air from the chamber, wherein the impeller is rotatably mounted in the chamber such that the housing defines an air pathway between the vents and the impeller. The multi-purpose tool also includes means for blocking the flow of air between vents and the impeller when the multi-purpose tool is in the trimmer mode of operation and means for disengaging the trimmer head from the internal drive shaft when the multi-purpose tool is in the blower mode.
摘要:
A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including a substrate, a thermochromic layer and a light absorbent layer such as carbon black located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The invention includes a method and apparatus for using the media in conjunction with labeling produce items.

A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including preferably transparent substrate, a thermochromic layer and a light absorbent layer located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The media optimally includes obscuration materials to reduce the visibility of the light absorbent layer to the naked eye. The light absorbent layer absorbs light in the NIR and visible light wavelength ranges of light and is preferably a low cost absorber such as carbon black. The invention also includes a manually operated produce labeling system utilizing the multi-layer laminate media. A rewinder is also provided which utilizes the multi-layer laminate media.
摘要:
A device for analysis of a sample, the device comprising: a first layer having a network of passages and chambers through which fluid is caused to flow during analysis; a second layer in which a plurality of chambers are formed, the chambers containing fluids for use in the analysis; an inlet in either the first or the second layer into which a sample to be analysed can, in use, be placed, and a third layer providing a frangible fluid seal between the chambers of the second layer and the network of the first layer so that, in use, a break in the third layer permits fluid from a chamber in the second layer to pass into the network of the first layer to enable analysis of the sample to be carried out.
