20150099455 | PATTERN CONTROLLERS FOR ACTIVE BEAM - Pattern controllers located in discharge slots of an active beam comprise a series of planar paddles hinged on an axis disposed at an angle to the planar surface of a side of the discharge slot thereby producing discharged air displacement in both the horizontal and vertical directions when the paddles are rotated. | 04-09-2015 |
20140284508 | Venturi Valve with Hard Stop - A Venturi valve has a Venturi housing with a plunger slidably mounted on a control shaft within the Venturi housing. Sliding movement of the plunger along the control shaft is controlled by a compression spring. A hard stop is fixed to the control shaft to limit the movement of the plunger along the control shaft in order to keep the compression spring from over compression and from a resulting loss of accuracy. | 09-25-2014 |
20110061967 | SOUND ATTENTUATOR - An apparatus and method for attenuating the sound generated by a fan powered terminal unit or other equipment in an HVAC (heating, ventilating, and air conditioning) system is described. The apparatus utilizes internal geometry to minimize noise due to air disturbances and aerodynamic effects within the apparatus. Specifically, a silencer is described comprising a casing having an inlet and an outlet; a condensate deflector positioned at the inlet to the casing; at least one baffle being operable to attenuate noise in a gas flowing through the silencer; and an air pathway through the silencer, defined by positions of the condensate deflector and the at least one baffle within the casing. The air pathway is angled or curved to substantially minimize the line-of-sight pathway from the inlet to the outlet. | 03-17-2011 |
