Abstract: Disclosed is a magnetic bar which is attached to the tines of leaf rakes for a purpose of retrieving nails from landscaping surrounding construction jobs. As most magnetic devices only collect nails which are loosely scattered above the soil, and that are in unobstructed areas, the disclosed invention is needed to collect those nails which are semi-embedded in the soil and that lay in bushes and in other tight places. The bar is situated along the tines of the rake and, as the rake is used to clean up a job site, the tines free any nails and draw them to the magnetic bar. By having the tines of the rake draw the nails to or near the bar, the size of the bar itself can be reduced as a large amount of magnetic pull is no longer needed. This reduction in size will result in a lower cost of the tool. The magnetic bar also strengthens the tines by becoming a cross-brace. This will translate into fewer strokes of the rake to gather debris.

Abstract: A fuel nozzle for gas turbine combustors reduces combustion instabilities by injecting purge air into the combustor angularly instead of axially. The fuel nozzle has a substantially cylindrical body with a number of internal passages. One of the passages provides premix gas fuel to a plurality of fuel injectors attached to the fuel nozzle.
