Abstract: A holder for multiple remote control units includes a plurality of generally planar tiers pivotally coupled to a cylindrical support at one end. The tiers are pivotable to separate at angular positions and secured by an elongated fastener or the like. Embodiments are shown having two and three tiers. A plurality of hook and loop fabric fasteners are secured to the upper surfaces of each receiving tier and to the undersurfaces of the to-be-secured remote control hand units. In its preferred form, the holder is fabricated using a planar member having an aperture at one end thereof together with at least one member having a planar element including a cylindrical support having a passage defined therein. A threaded insert is press fitted within the passage to permit the attachment between the cylindrical support and the remaining structure using a threaded fastener. An extending base member forms a base extension for the bottommost planar tier for supporting the holder against tipping.

Abstract: An object of the invention is to cool a rich burn combustor without extracting excessive amounts of heat and to use the extracted heat. In accordance with the invention, a combustor (10) having a primary combustor (12) and a secondary combustor (13) with a throat (20) between them is provided with a jacket including a wall (27) radially outwardly of a wall (14) of the primary combustor (12). Steam is injected into a manifold (33) at the throat end of combustor (12) and flows in a plurality of spiral paths through the space between walls (14) and (27) to an outlet manifold (32) at the other end of combustor (12) becoming superheated. The superheated steam is employed to drive a stream utilization device. The spiral steam flow paths are established by barriers (38) wound in spiral fashion on the outside of wall (14) of the combustor (12). Another object is to minimize stress on the wall (14) of the primary combustor (12).

Abstract: A fuel combustor consists of an elongated casing 16 with an air inlet conduit portion 27 at one end, and having an opposite exit end 18. The casing is formed with an intermediate combustion space 19. An elongated heat pipe 29 is mounted longitudinally in the casing and is offset from and extends alongside the combustion space 19. The heat pipe 29 is in heat-transmitting relationship with the air intake conduit 27 for heating incoming air. Guide conduit structure 25 is provided for conveying the heated air from the intake conduit into the combustion space. A fuel discharge nozzle 26 is provided to inject fuel into the combustion space 19. A fuel conduit 32 from a fuel supply source 37 has a portion 33 engaged in heat transfer relationship of the heat pipe for preheating the fuel. The downstream end of the heat pipe 29 is in heat transfer relationship with the casing and is located adjacent to the downstream end of the combustion space.
