A register assembly includes a register louver defining a generally circular air passage in which air directing vanes are mounted. The register louver has a central hub in which a shaft is rotatably mounted. A plurality of closure segments are mounted for rotation relative to each other about the shaft axis. Each of the segments is capable of closing a portion of the circular air passage in the louver. In a first position, the closure segments are serially aligned and substantially overlapping each other, leaving a substantial portion of the air passage open. As the shaft is manually rotated, tabs and cooperating stop surfaces on adjacent ones of the closure segments cooperate to serially rotate the closure segments from the first position, through a number of intermediate positions, and toward a second position wherein only the edge portions of the closure segments are overlapping and the air passage is completely blocked.
Disclosed is a vent grill for a vehicle capable of simplifying the manufacturing process, decreasing the installation space, and supplying conditioned air extensively. The vent grill comprises a cover fixed to one end of the duct and provided with a circular installing hole and a guide groove formed below the circular installing hole. At the cover, there is installed a main body including an opening through which air is exhausted, plural wings rotatably installed at the opening, an interlocking member connecting the respective wings such that the respective wings are rotated at the same time, and a knob installed at either one of the respective wings. At the rear side of the main body, there is installed an opening and shutting unit including a housing provided with a penetration hole which is installed at a rear of the main body, fixed to the cover, surrounding the main body, for penetrating the air, and having a central shaft formed at a center thereof, a rotational plate rotatably installed at the central axis of the housing, for controlling an opening angle of the penetration hole, and a knob fixed to the rotational plate so as to rotate the rotational plate, and exposed through the guide groove of the cover.
A baffle system for control of fluid delivery using manual or automatic control. The fluid supply bore is controllably occluded using a plurality of individual baffle elements. Each of the individual baffle elements is secured at two places.
A convection braze furnace for brazing aluminum heat exchangers in an inert gas rich atmosphere includes entrance and exit vestibules forming atmosphere barriers of suspended stainless steel strips. The interior of the braze furnace is divided into multiple zones for progressively heating the heat exchangers to a brazing temperature and then cooling the heat exchangers in the final zone. An impeller circulates the heated intent gas atmosphere within each zone to accelerate heat transfer. A chain type conveyor supports the heat exchangers as they are moved through the braze furnace. An isolated return tube surrounds the lower return side of the conveyor chain as it passes through the braze furnace. The braze furnace housing is comprised of inner and outer shells having an inert gas pressurized interstitial cavity therebetween. The inner shell includes a plurality of expansion strips having generally ellipsoidal corner expansion joints.
A damper utilizing a frame having a base and a wall portion extending outwardly from the same. The wall portion supports a stepped edge which is positioned to at least partially circumvent and aperture formed by the frame. A plurality of flanges are positioned in overlying relationship and slidably move relative to one another by a mechanical mechanism. A plurality of flanges ride on a stepped edge portion to cause fanning of the flanges across the aperture to selectively occlude the aperture or a portion thereof.
A damper control system which employs an unsheathed cable to transmit torque from a torque inducing tool to a damper regulator for regulating a damper of an air processing system. The damper control system has a first cable bracket with a first bracket passage through which the unsheathed cable passes. The first cable bracket is designed to be affixed to a surface accessible to the torque inducing tool. Longitudinal motion of the unsheathed cable with respect to the first cable bracket is limited by a pair of first bracket clips attached to the unsheathed cable and positioned such that the first bracket passage is interposed therebetween. The unsheathed cable is provided with a first cable end which can be engaged by the torque inducing tool and a second cable end which is either permanently affixed to or can be maintained slidable engaged with the damper regulator. Such engagement can be maintained by a set screw in the damper regulator or by a second cable bracket which is fixed with respect to the damper regulator. The second cable bracket has a second bracket passage through which the unsheathed cable passes and a second bracket clip positioned on the unsheathed cable between the second cable end and the second bracket passage.
