An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet [1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...
Spark arresters are also fitted to the top of a flue (or a chimney pot) to prevent floating embers from a fire (particularly one burning wood) setting light to a flammable roofing surface (shingle, thatch, or bitumen-felt) or falling onto combustible material on the ground.
Moving heads connected to a plug-in box (center). In stage lighting, a plug-in box, plug box [1] or drop box [2] is a device, similar to a power strip, to distribute power to multiple lighting instruments, consisting of an inlet (either detachable or hard-wired), and multiple female outlet connectors or pigtails.
The dimensions of the blastpipe and chimney are critical to the steam-generating capacity of the locomotive and its fuel economy, since there is a natural trade-off between a high-velocity steam jet giving a strong draw on the fire, and back-pressure on the exhaust. Small changes to this "front end" design can have a dramatic impact.
The flat parallel plug blades are polarized to prevent the hot and the neutral connections from being reversed. In addition, many versions have a molded obstruction bump on top of the adapter, to block the grounding prong and thus physically prevent forcible insertion of a 3-prong plug in the wrong orientation.

A chimney cowl or wind directional cap is a helmet-shaped chimney cap that rotates to align with the wind and prevent a downdraft of smoke and wind down the chimney. An H-style cap is a chimney top constructed from chimney pipes shaped like the letter H. It is an age-old method of regulating draft in situations where prevailing winds or ...
Soon after the power of the steam blast was discovered it became apparent that a smokebox was needed beneath the chimney, to provide a space in which the exhaust gases emerging from the boiler tubes can mix with the steam. This had the added advantage of allowing access to collect the ash drawn through the fire tubes by the draught.
Some types of conduit are approved for direct encasement in concrete. This is commonly used in commercial buildings to allow electrical and communication outlets to be installed in the middle of large open areas. For example, retail display cases and open-office areas use floor-mounted conduit boxes to connect power and communications cables.
