20080283444 | MULTI-STAGE HYDROCRACKER WITH KEROSENE RECYCLE - This invention relates to a multi-stage process for hydroprocessing gas oils. Preferably, each stage possesses at least one hydrocracking zone. The second stage and any subsequent stages possess an environment having a low heteroatom content. Light products, such as naphtha, kerosene and diesel, may be recycled from fractionation (along with light products from other sources) to the second stage (or a subsequent stage) in order to produce a larger yield of lighter products, such as gas and naphtha. Pressure, in the zone or zones subsequent to the initial zone is from 500 to 1000 psig lower than the pressure in the initial zone, in order to provide cost savings and minimize overcracking. | 11-20-2008 |

20090183418 | SWIMMING FROG LURE AND METHOD - A frog lure device that has a life-like swimming action. In a preferred embodiment, the device has a diving “collar” disposed around an upper region of the lure body, rather than a lower region, which is common in conventional lure devices. In a specific embodiment, the collar caused the lure body to dive under the surface like a frog. Concurrent with the diving action, the lure device also has a kicking action to resemble a living frog device. In a specific embodiment, the collar also forms a trail of one or more bubbles and a vortex, or slight vacuum behind it. In a specific embodiment, the lure body includes a pair of legs, which have a suitable length to be caught in the vortex and become trapped in the vortex the pair of legs also straighten out to cause a kicking action and also provide stability to the lure body as it accelerates through the water. As the frog device traverses through the water, the legs also slightly contract and extend to resemble a kicking action. In other embodiments, the frog lure device can be crawled across surface vegetation. When given a single pull followed by a rest, the frog lure responds by diving from a surface region of the water (or suspended position) to a depth beneath the surface region at an angle not unlike a real frog. Concurrent with the diving action, the frog lure straightens its legs imitating a kicking action as it moves forward. As the lure comes to rest again, the legs coupled to the lure retract. Just like a real frog! | 07-23-2009 |
