Abstract: A suction apparatus useful as a vacuum pump, aerator or the like comprises a fluid inlet housing having a nozzle support plate which includes a plurality of nozzles having a discharge outlet located within a suction chamber. These nozzles each align with the passageway of a hollow suction tube having an inlet within the suction chamber and an outlet spaced from a deflector plate. A fluid such as liquid is ejected from the discharge outlet of the nozzles and in the course of passage into the suction tubes a negative pressure is created within the suction chamber which draws a second fluid such as air through the suction chamber and into the passageway of the suction tubes for combination with the liquid therein forming a combined liquid-gas fluid stream.

Abstract: A bracket for mounting a fixture on a wall of a building. The bracket includes a hollow neck structure. At one end of the neck structure is flange means which is mounted on sheathing of the wall. The other end of the neck structure is closed by a main plate. An edge portion of the main plate extends outwardly of the neck structure spaced from the flange means to form an annular socket in which edge portions of siding of the wall terminate. The fixture can be mounted on the main plate, and access to the fixture can be had through an opening in the main plate.
