Assignee:

CMI Corporation - Oklahoma City OK

International Classification:

B28C 546

US Classification:

366 25, 34137, 432111

Abstract:

A drum mixer for heating, mixing and drying an aggregate material, such as a mixture of recycled asphaltic pavement and virgin aggregate. The drum mixer includes an inclined drum having a first end and a second end. The drum forms a pre-heating/blending section adjacent the first end, a heating/mixing section adjacent the second end, and a heating/drying/mixing section therebetween. A feed assembly for feeding aggregate material, preferably having a high ratio of RAP material to virgin aggregate, is provided. The feed assembly feeds the aggregate material into the pre-heating/blending section of the drum for movement of the aggregate material sequentially through the pre-heating/blending section, the heating/drying/mixing section and the heating/mixing section. A burner assembly extends from the second end of the drum into the heating/drying/mixing section of the drum. The burner assembly creates a high temperature gas stream which flows through the heating/drying/mixing and pre-heating/blending sections of the drum.

Assignee:

General Electric Company - Schenectady NY

International Classification:

B01F 3/04

US Classification:

261116, 96355, 96356

Abstract:

An embodiment of the present invention provides an air conditioning system (ACS) for conditioning the airstream entering an air-consuming machine, such as, but not limiting of, a gas turbine. Conditioning may be considered a process that adjusts at least one physical property of the airstream. The physical property may comprise: a wet-bulb temperature, a dry-bulb temperature, relative humidity, density, or the like. In an embodiment of the present invention, the major components of the ACS may be located in a single structure, which may be considered a module. Depending on the application of the ACS, multiple modules may be physically and/or operationally integrated on the air-consuming machine. An alternate embodiment of the ACS may comprise a module having multiples stages. Here, each stage may operate independently other stages.

US Classification:

60728, 60 3953, 60 393, 60775

Abstract:

A system for conditioning an airstream entering an air-breathing machine includes an air conditioning system (ACS) configured for adjusting a physical property of the airstream, wherein the ACS comprises a module. The module includes a non-media conditioning system configured for adjusting a physical property of the airstream if an ambient condition is within a range, wherein the non-media conditioning system comprises nozzles adapted for spraying a fluid onto the airstream. The module also includes a media conditioning system configured for adjusting a physical property of the airstream to provide additional output of the air-breathing machine, wherein the media conditioning system comprises a direct exchange medium and a fluid distribution manifold. The ACS operates in a direct evaporative mode if the fluid is approximately greater than a dew point temperature and operates in a direct chilling mode if the fluid is approximately less than a dew point temperature.

International Classification:

F02G 3/00

US Classification:

60 39093, 219679

Abstract:

An ice and/or frost preventing system for positioning in an airflow tunnel having an air inlet includes a plurality of waveguide passages positioned in the airflow tunnel; an air filter positioned in each waveguide passage; a microwave energy source coupled to each waveguide passage; a first screen positioned in the airflow tunnel upstream of the plurality of waveguide passages; and a second screen positioned in the airflow tunnel downstream of the plurality of waveguide passages. The microwave energy sources and the first and second screens create a guided, standing wave, microwave energy that substantially prevents at least one of ice and frost from forming on the air filters. A turbine system including the ice and/or frost preventing system is also described.
