Abstract: A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

Abstract: A steam dispersion system is disclosed. The steam dispersion system includes a header and a mounting plate spaced from the header. A steam dispersion tube including a first end and a second end and an interior cavity defined between the first end and the second end is mounted between the mounting plate and the header. The steam dispersion tube defines a longitudinal axis. A biasing structure is mounted between the mounting plate and the header, wherein the biasing structure applies a biasing force on the steam dispersion tube along a direction parallel to the longitudinal axis of the steam dispersion tube when mounted between the header and the mounting plate.

Abstract: A heat transfer system includes a steam chamber that communicates in an open-loop arrangement with a first steam source for supplying steam to the steam chamber, the steam chamber including a steam exit for supplying steam to air at atmospheric pressure. A heat transfer tube communicates in a closed-loop arrangement with a second steam source for supplying steam to an interior surface of the heat transfer tube, the heat transfer tube vaporizing condensate forming within the heat transfer system back to steam that is supplied to the air via the steam exit. The outer surface of the heat transfer tube is configured to contact the condensate and vaporize the condensate back into steam, wherein the heat transfer tube includes a plurality of pockets formed on the outer surface of the tube, each pocket including a pocket exit/entry portion having a smaller cross-sectional area than the cross-sectional area of the pocket at a root portion thereof adjacent the outer surface of the tube.

Abstract: A steam dispersion system is disclosed. The steam dispersion system includes a header, a divider dividing the header into at least two interior chambers that are generally not in fluid communication with each other, and at least two steam dispersion tubes, each steam dispersion tube communicating with only one interior chamber. Each interior chamber includes a separate steam flow valve for independently controlling the amount of steam flow to each chamber based on the difference between a measured humidity value and a predetermined desired humidity value.

Abstract: The mobile stand is generally L-shaped in side elevation, having a horizontally extending base and an upright mast adjacent the rear of the base. The base is somewhat H-shaped in top plan, having a pair of widespread, parallel, horizontal legs that extend slightly rearwardly beyond the mast, and a crossbar that rigidly interconnects the legs adjacent their rear ends. The mast is fixed to the crossbar midway between the two legs. Four rubber stabilizer feet project downwardly from the base at its four corners to space the base a short distance above the floor. Transport wheels at the rear ends of the legs project downwardly from the base but do not engage the floor when all four of the feet are touching the floor, thus rendering the wheels ineffective at such time.

Abstract: A hub puller device to simplify the removal of the hub from the wheel bearing on front wheel drive cars when maintenance is required. In the preferred embodiment, the device includes a U-shaped frame, a forcing screw, traveling nut and a pushing piece. A maintenance technician installs the forcing screw to extend through the open cylindrical section of the hub and mounts the pushing piece and the traveling nut on the forcing screw adjacent the cylindrical section. Next, the technician installs the frame to wrap around the spindle housing such that one member abuts the front surface of the spindle housing. The other frame member braces the receiving end of the forcing screw and prevents linear movement of the forcing screw. With the setup completed, the maintenance technician rotates the forcing screw and prevents rotation of the traveling nut.

Abstract: A strut spring compressor (20) having a support frame (22), a plurality of pivot arms (24, 26, 28, 30), a plurality of spring clamps (32, 34, 36, 38), and an actuating mechanism (40) is utilized to compress and expand a spring (42) of a strut assembly (44) whereby maintenance can be performed on the strut assembly (44). Each of the pivot arms (24-30) is pivotally attached to the support frame (22) by ball joints (74) which permit the arms (24-30) to pivot independently and three-dimensionally to compensate for a variety of spring sizes, and the spring clamps (32-38) are pivotally attached to the arms (24-30) to compensate for a variety of spring pitches. The actuating mechanism (40) includes a forcing screw (116) pivotally joined to a top trunnion assembly (118) and threadably engaging a middle trunnion assembly (120) and a bottom trunnion assembly (122).
