Abstract: The current invention is a pet food tray a bottom reservoir filled with water which is covered by the top that prevent bugs from getting into the pet food. The reservoir is in the base of the tray and is covered with a top so that no contaminants can get into the water. The top edge of the reservoir has a curved lip to prevent spills. The pet tray will accommodate large and small bowls for kibbles, canned food or water.

Abstract: A nail brush comprising; a handle section; a plurality of bristles, each of said bristles having an attached end, connected to said handle section, and a free end; each free end positioned, relative to its neighbours, to collectively define an envelope partially enclosing a volume; wherein said volume is structured to receive a portion of at least one human digit extending from a digit tip substantially to an eponychium of said digit.

Abstract: In one embodiment, a system includes an engine that includes a combustion chamber and a viewing port into the combustion chamber. The engine also includes a camera configured to obtain an image of a flame in the combustion chamber through the viewing port and a controller configured to adjust a parameter of the engine based on the image of the flame.

Abstract: A combustor for a gas turbine includes a plurality of radially outer nozzles arranged in an annular array, each of the radially outer nozzles having an outlet end located to supply fuel and/or air to a first combustion chamber. A center nozzle has an outlet end located axially upstream of the outlet ends of the radially outer nozzles, and is configured and arranged to supply fuel and air to a second combustion chamber axially upstream of the first combustion chamber. The second combustion chamber opens into the first combustion chamber and has a length sufficient to maintain a center nozzle flame confined to the second combustion chamber.

Abstract: A gas turbine combustion system for burning air and fuel into exhaust gases. The gas turbine combustion system may include a combustor, a turbine nozzle integral with the combustor for providing the air to the combustor, and a fuel injector for providing the fuel to the combustor. The turbine nozzle and the fuel injector are positioned within the combustor such that a mixture of the air and the fuel flows in a first direction and the exhaust gases flow in a second direction.
