Abstract: The invention relates to a wall element for a wall structure of a gas turbine engine combustor. The wall element has an inner, in use, hot surface, and an outer, in use, cooler surface. A plurality of projections is provided on the outer surface to facilitate heat transfer to a coolant flow. The wall element comprises a means to direct more coolant flow at a hot-spot on an adjacent tile than the remainder of the adjacent tile and thereby reducing the thermal gradient across the adjacent tile.

Abstract: An apparatus to assist in cooking over a campfire is herein disclosed, comprising a generally “Y”-shaped support that rests over an open fire by means of three (3) legs. An adjustable steel cable, controlled by a mechanically-operated winch, is provided at the center of the “Y”-shaped support, which depends downward and connects centrally to four (4) chains, each of which connects to a corner of a rectangular grilling surface. The grilling surface comprises a heat-resistant material and can be made in varying dimensions. The grilling surface is height-adjustable to accommodate cooking needs and fire output permits. Once cooled, the apparatus can be disassembled and transported in a supplied pouch or hard case.

Abstract: A combustor wall element arrangement for a gas turbine engine comprises an upstream wall element (50A) overlapping a downstream wall element (50B) and defining a gap (37) and an outlet (35) therebetween. In use, a coolant flow exits the outlet (35) to provide a coolant film (D) across at least a part of the downstream wall element (50B). The outlet (35) has a smaller dimension, normal to the downstream wall element (50B), than the gap (37) thereby increasing the velocity of the coolant flow across at the downstream wall element (50B). The resultant film coolant flow is effective further across the downstream wall element.

Abstract: A system for producing plasma tubes that can withstand a wide variety of physical and environmental stressors within a plasma processing system is disclosed. Within such a plasma processing system, a plasma tube structure has a central body portion—having a fixed outer diameter. At a first end of the plasma tube structure, an outwardly extending flange may be provided. At a second end of the plasma tube, an edge portion is provided—having an outer diameter that is less than the fixed outer diameter of the central body portion. The edge portion is formed to facilitate easy and secure engagement of the plasma tube structure with a compression mechanism. The plasma tube structure is formed of material that provides sufficient structural integrity and degradation resistance.

Abstract: A high efficiency heat exchanger is shown which can be incorporated into a finned tube water heater. The heat exchanger has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. When incorporated into a water heater, a burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle.
