Patent CA-2199883-C (CA)
Title: Modular supertile array antenna
Inventor: STUART THOMAS MACKENZIE
IPC: H01Q21/00
Filed: 1997-03-13
Granted: 2003-02-04
Abstract: An array antenna especially adapted for spacecraft use includes a support frame made up of intersecting beams which form an "eggcrate" of square openings.  A plurality of subarrays or radiating tiles are dimensioned to fit within the openings.  Distortion of the support frame due to external forces, or due to expansion and contraction of the radiating tiles, is accommodated andor resisted by a four-point mounting arrangement for each tile. Each mounting is located on the center of the sides of the radiating tile, and the corresponding center of the side of the opening in which it fits.  Each mounting consists of a thin, flexible mounting beam, extending parallel to the associated support beam, and fastened to the support beam at the ends of the mounting beam.  The center of the side of the tile is fastened to the center of the flexible support beam, so expansion and contraction of the tile are compensated by bending of the flexible beam.  Mutually opposing external forces acting parallel to the elements of the support frame are resisted by the longitudinal stiffness of the flexible beam and the diagonal stiffness of the tile.

Abstract: A catenary riser support tube that receives the riser and is attached to the floating offshore structure. The support tube is attached to the floating offshore structure at an angle from the vertical so as to be in line with the natural angle that the installed catenary riser would assume on a calm day. The support tube is attached to the floating offshore structure at different points along the length of the support tube and thus flexes about its attachment points to the floating structure. This minimizes stresses on the catenary riser.

Abstract: Apparatus and method to improve flow of fluid through an annular bed in a radial flow treatment vessel. An elongated annular baffle is disposed in the reactor adjacent the bed to impart generally U-shaped flow to the fluid either prior to entering or after it exits the bed thus achieving an overall serpentine or reverse U-shaped flow pattern as the fluid proceeds from an entry port to an exit port in the reactor. Means are provided in the baffle to permit minor amounts offluid to bypass the generally U-shaped flow path in order to correct fluid flow maldistribution through the bed that is attributed to frictional pressure drop in the flow channels adjacent to the bed. A vessel according to the invention can be operated with fluid flow through the vessel in either direction.

Abstract: A heated seat assembly especially suitable for outdoor use. A heater insert is positioned in the hollow of the seat cushion and includes a substrate member and a thin film heating element positioned on the substrate member. The heater insert is inserted into the hollow of the cushion through a slot in the rear edge of the cushion to position the thin film heating element within the hollow of the cushion beneath the seating surface. The heater insert is held in position by positioning of the forward edge of the substrate member in a crevice defined interiorly of the cushion proximate the front end of the cushion and by adhesive securement of a handle portion of the heater insert against an outer face of the rear edge of the cushion. Leads extend from terminals of the heating element to a plug in the handle portion of the insert which may be accessed by a plug of a pigtail cord extending from a junction box positioned on a riser surface of a grandstand immediately behind the seat assembly. Expanded foam is delivered into the hollow of the cushion beneath the substrate member to fill the area beneath the substrate member to discourage downward migration of heat generated by the heater insert and direct the generated heat upwardly to the seating surface. A similar heater insert is positioned in the seat back of the seat assembly and includes an exterior plug which may be connected by a further pigtail cord emanating from the junction box.

Abstract: An independent and conserved source of fuel and/or power comprises a top stage rocket engine firing up to 5000 F at very high pressures, delivering jet flows up to transonic velocities into a near adiabatic tunnel for mixing in general and/or for transforming reactants introduced to suit specific objectives. The related compression is supplied by an independent prime mover which compresses its exhaust and other recoverable fluids. Low grade flows, thereby upgraded in temperature and pressure, are adiabatically contained, are further upgraded in the tunnel to become part of the prescribed fuel for export at the tunnel ends; or fuel to be fired in a prime mover for electric or other power; or hydrogen for chemical use. Expansion turbines for this purpose are relieved of the load used to compress the excess air in standard gas turbines thus increasing export power. A portion of the expansion turbine's exhaust becomes part of recoverable fluids. When oxygen is used instead of air, the gases through turbines are nitrogen-free with more heat capacity reducing turbine inlet temperatures for the same power. When reactant transformation is specified, the larger water vapor content in the cycle enhances the water gas/shift autothermally for ammonia and/or power and alternatively for pyrolysis cracking for olefins and diolefins. Further, staging rocket engine reactors increases efficiency in boilers and steam turbines; and staging can produce sponge iron and/or iron carbide as well as expansion turbine power and fuel cells for peak and off-peak loads.
