Abstract: A work machine, such as a skid steer loader or a compact track loader, includes an air intake assembly for a heating, ventilation, and air conditioning (HVAC) unit. A conduit integrated into a structure supporting a roof over an operator cab accepts air and water from the atmosphere through an air inlet proximate the roof. A debris outlet downstream in the conduit allows gravity to return the water to the environment. Between the air inlet and the debris outlet, an orifice in the conduit connects to an air duct through which the air may be diverted by suction from the HVAC unit. An air filter at the end of the air duct removes remaining particulates from the air prior to conditioning by the HVAC unit. Sizing the cross-sectional areas of the air path to exceed a cross-sectional area of an inlet to the air filter and providing a substantially straight air path avoids resistance to air flow, resulting in efficient intake of cleaner air.

Abstract: A gas processing system for recovering methane gas from a landfill includes a high pressure main absorber plus a relatively low pressure one. The low pressure absorber receives a gas stream from an equally low pressure flash tank. This low pressure gas stream consists mostly of carbon dioxide and methane. The methane would normally be lost due to the high cost of recompressing the carbon dioxide, but by running this mixture of carbon dioxide and methane through the low pressure absorber with a slip stream of cold absorbent, a large portion of the carbon dioxide can be removed with negligible methane losses. The remaining methane can be recycled through the high pressure main absorber without having to recompress the removed portion of carbon dioxide.

Abstract: A vacuum cleaner or a docking station has momentum separator having first and second sidewalls which are porous.

A second air flow chamber is located exterior to the momentum separator between a second end wall, which is spaced from and faces the second side screen, and the second side screen. In operation, air exits the momentum separator through the first and second side screens and travels through the first and second air flow chambers to the air outlet of the first and second air flow chambers.
