Squeezing the spring loaded hand grip by a hand drives the saw-tooth drive plate against the lower drive gear which in turn drives the upper drive gear forward to be meshed against the fan blade gear and causes the upper drive gear and the fan blade gear to rotate. Releasing the spring loaded hand grip allows the upper drive gear and the fan blade gear to be unmeshed and continue rotating. The fan blade gear is attached to the fan blade shaft to allow for continuous rotation of the fan blades through the squeezing and releasing of the spring loaded hand grip to create a cooling breeze. | 12-13-2012 |

| 20120213648 | COMPRESSOR - A compressor compressing a fluid including lubricating oil includes, on the discharge side thereof, a first separation chamber for separating the lubricating oil by generating a swirling flow in the fluid. The first separation chamber includes: a circumferential wall; an inflow port that is formed in the circumferential wall and causes the fluid to flow into the first separation chamber; and a guiding plate extending from the circumferential wall. The guiding plate extends so as to face the inflow port in a direction where the fluid flows from the inflow port into the first separation chamber, and so as to deflect the fluid flow from the inflow port to guide it along an inner circumferential surface of the circumferential wall. | 08-23-2012 |
| 20120237371 | Reciprocation Compressor - [Object of the Invention]An object of the present invention is to provide a reciprocation compressor comprising an extraction passage connecting a crank chamber with an inlet chamber, an aperture disposed in the extraction passage and a filter capturing foreign matters flowing from the crank chamber to the inlet chamber, wherein the foreign matters captured by the filter is restrained from returning to the crank chamber even if reverse flow of refrigerant from the inlet chamber to the crank chamber is generated, and the filter does not restrict design specifications of other members of the compressor. | 09-20-2012 |
| 20120076673 | Mounting Device With Splined Washer - A mounting device mounts a mounting foot to another member, such as a base pan. The mounting device includes a grommet, a splined washer and a fastener. The grommet has an axially extending post for receiving a mounting foot. The splined washer is configured to lock into the mounting foot and the post. The splined washer has an inner bore for receiving the post. The fastener is received on the post and maintains the splined washer and the mounting foot on the post. | 03-29-2012 |
| 20120263608 | Pump Casing And Related Apparatus And Methods - A pump casing has a metallic band that defines a sidewall of the pump casing and having at least one tab projecting from a surface thereof or at least one opening. The pump casing also has first and second plates disposed opposite one another, with the metallic band being disposed there between, and with the first and second plates and the metallic band jointly defining a chamber of the pump casing. At least one of the first or second plates includes at least one tab or at least one opening respectively cooperating with the at least one opening or the at least one tab of the metallic band so as to retain a formed shape of the metallic band in the pump. The at least one opening may, for example, be a slot in the at least one of the first or second plates. | 10-18-2012 |
| 20110123364 | DEPLOYMENT MECHANISM AND METHOD FOR OVERBOARD PUMP - A deployment system is utilized to deploy an overboard pump over the side of an offshore rig or vessel. A reel of hose with an overboard pump is securable to an end of the reel of hose. A bend restrictor supports the hose as the hose bends downwardly for deployment in water. The bend restrictor is mounted for movement with respect to the reel whereby the bend restrictor is movable away from the reel, preferably along a fixed and predetermined path, to a deployment position to permit the overboard pump and the hose to be deployed into the water over the side of the offshore rig. The bend restrictor is also movable to a non-deployed position such that the hose guide is above the rig floor where the pump may be serviced. | 05-26-2011 |
| 20110014066 | GARDEN HOSE BOOSTER WATER PUMP SYSTEM - A booster pump system, for boosting a flow of water from a water source, includes a housing having a retractable handle. The booster pump system also includes a water pump positioned within the housing. The pump has an inlet and an outlet, and is designed to raise the pressure of the flow of water by an amount in a range of 20-200 pounds per square inch. The pump is also designed to raise the flow rate of the flow of water by an amount in a range of 0.5-5 gallons per minute. The booster pump system further includes a hose reel positioned within the housing, where the hose reel supports a garden hose attached to the outlet of the pump. | 01-20-2011 |
| 20110038741 | System, Method, and Pump to Prevent Pump Contamination During Negative Pressure Wound Therapy - A pump assembly suitable for negative pressure wound therapy that includes an internal filter for preventing contamination in various components of the pump assembly, such as the pump unit. The internal filter is located in an isolated filter chamber, and inlet vacuum tubing that could contain fluids or bacteria are located inside a double containment sleeve to prevent contamination of components of the pump. The inlet vacuum tubing may be removed without opening the main pump housing and without contaminating the contents of the pump housing. | 02-17-2011 |
| 20120275936 | AIR COMPRESSOR - An air compressor comprises a compressing device driven by a motor, a heat exchanger cooling the first air compressed by the compressing device by the second air blowing from a blower, an intake path through which the first air sucked by the compressing device flows, a discharge path through which the second air blown by the blower and heated by the heat exchanger flows, and a dehumidifying rotor that carries an adsorbent adsorbing moisture from the first air, the moisture being removed by the second air to restore the adsorbent. | 11-01-2012 |
