American Society of Heating and Ventilating Engineers Guide, 1934 Positive Acting: A thermostat, humidistat or relay which maintains its valve or damper either wide open or fully closed, that is, when there is always full force or none in its branch line.

\ American Society of Heating and Ventilating Engineers Guide, 1934 Down-Feed Gravity One-Pipe Air-Vent System In the overhead down-feed gravity one-pipe air-vent system there is no change over the up-feed system in the radiators, the radiator valves, the air valves, or the radiator runouts as far back as the risers.

\ American Society of Heating ar.d Ventilating Engineers Guide, 1934 To bring this about, it is necessary in some cases to minimize the friction, i.e., to make the pipe line as short as possible and to provide as few fittings as possible; and in other cases it is necessary to increase the length of the pipe and the number of fittings so that, for every circuit, the friction head will be equal to the available pressure head.
