| 20080290533 | Demand activated steam dispersion system - 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. | 11-27-2008 |
| 20090121367 | Heat exchanger for removal of condensate from a steam dispersion system - 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. | 05-14-2009 |
| 20090166018 | HEAT TRANSFER SYSTEM INCLUDING TUBING WITH NUCLEATION BOILING SITES - 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. | 07-02-2009 |
| 20090179337 | Quick-attach steam dispersion tubes and method of attachment - 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. | 07-16-2009 |

| 20100251548 | INSULATION FOR A STEAM CARRYING APPARATUS AND METHOD OF ATTACHMENT THEREOF - A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft̂2 deg F). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit. | 10-07-2010 |

| 20110284545 | Container Assembly with Flexible Lid Seal - A storage container assembly comprises a storage receptacle and a removable lid. The storage receptacle has a base and a continuous sidewall connected to the base. The sidewall projects upward from the base to a peripheral edge. The removable lid has a rigid central cover portion and a flexible seal portion that traverses a perimeter of the rigid central portion. The flexible seal portion has a release tab disposed along its periphery, and a pocket disposed inward of the release tab. The flexible seal portion further has a ledge disposed generally at the periphery of the flexible seal portion. The ledge contacts the peripheral edge of the storage receptacle. The flexible seal portion further has and a blade portion disposed below the ledge. The blade portion contacts the side wall of the storage receptacle and forms a generally fluid-tight seal with the sidewall. | 11-24-2011 |

| 20080238160 | Seat mechanisms - Described are several mechanisms for permitting a user to adjust the seat on a stationary exercise bicycle. The described mechanisms can be used to adjust the height of the seat or the fore and aft positioning of the seat on an upright type bicycle. Each of the described mechanisms can be configured to provide users with an optimum seat position and with a convenient latch mechanism to adjust the position of the seat. | 10-02-2008 |
| 20080238161 | Recumbent seat mechanism - Described are several mechanisms for permitting a user to adjust the seat on a stationary exercise bicycle. The described mechanisms can be used to adjust the height of the seat or the fore and aft positioning of the seat on an upright type bicycle. Each of the described mechanisms can be configured to provide users with an optimum seat position and with a convenient latch mechanism to adjust the position of the seat. Also described is a seat mechanism for use with a recumbent type stationary exercise bicycle where the seat can be adjusted along the longitudinal length of the bicycle. | 10-02-2008 |

| 20080289883 | AUTOMATIC LIVESTOCK WEIGHING SYSTEM - A system for weighing a plurality of quadruped animals is for use in a pen confining the animals. The pen has at least first and second segregated spaces with a first one-way chute allowing animal passage from the second space to the first space. A weighing station is located within a passage having an entrance and an exit, and that allows animal passage from the first area to the second area. The weighing station includes a weighing platform within the passage over which an animal must pass when passing from the first to the second space. The weighing platform has inlet and exit scales that support the weighing platform adjacent to inlet and exit ends thereof, and provides inlet and exit weight signals. A controller receives the inlet and exit weight signals and uses them in an iterative process to determine the presence of a single animal on the weighing platform. Once that determination is made, the sum of the inlet and exit weight values is very likely to accurately provide the animal weight. The controller may also use the inlet and exit weight signals to control closing of an inlet gate to bar more than one animal at a time from the weighing platform. An animal sorting system can easily incorporate this weighing system to provide more accurate sorting. | 11-27-2008 |
