For the latter purpose, Westinghouse gas-regulators are employed, the positions of the regulators being so chosen as to equalize the pressure throughout the service.
Although the Regulators assembled to the number of about 3700 they were not prepared to withstand the governor's force and again submitted without bloodshed, there being only a few arrests made.
These riotous proceedings provoked the second military expedition of the governor, and on the 16th of May 1771, with a force of about r000 men and officers, he met about twice that number of Regulators on the banks of the Alamance, where, after two hours of fighting, with losses on each side nearly equal, the ammunition of the Regulators was exhausted and they were routed.

The adjustment of the air currents in the different splits is affected by regulators which are placed in the return air-ways, and act as throttle valves to determine the volume of air in each case.
