Filed:

Oct 1, 2008

Appl. No.:

12/243744

Inventors:

Paul Cramer - San Clemente CA, US
Steven Coffman - Moreno Valley CA, US

Assignee:

Cramer Decker Industries - Santa Ana CA

International Classification:

B65D 19/42

US Classification:

280 4314, 1378993, 211 8518, 280 4324, 280 793, 414608

Abstract:

A mobile cart for carrying a plurality of fluid canisters. The cart includes a platform configured to support the fluid canisters. The cart also includes a base having a base body and a plurality of wheels movably connected to the base body so that the wheels can be selectively moved with respect to the base body between an extended position and a retracted position. In the extended position, the plurality of wheels extends from the base body so the cart can roll, on the plurality of wheels, over the support surface supporting the cart. In the retracted position, the plurality of wheels is retracted relative to the base body so that the cart cannot roll, on the plurality of wheels, over the support surface.

Abstract:

A feed element-to-beam interconnection network is provided for an antenna that transmits and receives a large number of beams, such as 87 contiguous narrow beams that cover the United States. The network, which is connected to a layer of 134 feed elements that transmit and receive microwaves, consists of a pair of circuit boards (160c, 162c in FIG. 7) parallel to the feed element layer. One of the two boards has 87 dividers (e. g. 51td, FIG. 5) that each divide a signal to be transmitted into seven portions, and the other board has 134 combiners (e. g. 38tc) that each collect seven transmit signal portions and deliver the sum to one of the feed elements. A similar arrangement is used to handle received signals, with 134 receive signal dividers (e. g. 38rd) on the one board, and 87 receive signal combiners (e. g. 51rc) on the other board.
