| 20080283476 | Fluid filter and filtering method - A fluid filter is preferably constructed from a relatively thick batting of high loft, non-woven, fluid permeable fibrous material. The filter batting is then passed through a manufacturing device, which slices the batting in the vertical as to create two continuous filter batts from the parent filter batt. The slicing also creates a relatively deep V-shaped zig zag or waveform pattern in the anterior filter surfaces of the top and bottom of the batt. The top half deep V-shaped zigzag patterns peaks and valleys correspond or line up with the bottom half's valleys and peaks since the waveform landscape of the first child batt is essentially a negative impression of the second child batt. Accordingly, the patterns nest within one another. When separated, the two children batts each comprise a waveform landscape for dynamically directing fluid streams from the anterior filter surface to the posterior filter surface. | 11-20-2008 |

A filter insert is arranged in the filter housing and divides an interior of the filter housing into an inlet region connected to the fluid inlet and an outlet region connected to the fluid outlet. The filter insert has a filter medium for filtering fluid. | 01-28-2016 |
| 20160039691 | PRESSURE CYCLING WASTEWATER TREATMENT APPARATUS - A pressure cycling wastewater treatment apparatus can include a confined chamber which encloses an interior volume. The confined chamber can have a wastewater inlet through which wastewater can flow into the confined chamber. In addition, an expansion 5 fluid inlet can receive an expansion fluid into the confined chamber. A treated water outlet can allow treated water to flow out of the confined chamber. Within the interior volume of the confined chamber, a mechanical pressurizing element can be configured to move in a cyclical pattern. Motion of the mechanical pressurizing element can cyclically compress and decompress a mixture of wastewater and expansion fluid inside the confined chamber. 10 The motion of the mechanical pressurizing element can be driven by a driving unit connected to the mechanical pressurizing element through a crankshaft. | 02-11-2016 |
| 20160145885 | JET PROPELLED POOL CLEANER - A pool cleaner having two tilted pumps pointing in opposite directions, which propel the pool cleaner. In an embodiment, the pumps are turned on alternatively to alternate the direction of travel of the pool cleaner. In an embodiment, each pump has a discharge opening facing upwards at an angle, covered by an adjustable flap. The flap can be adjusted to open to different degrees to change the speed of the pool cleaner. The flap is attached to a ring that rotates and thereby rotates the angle of the orientation of the flap. Adjusting the angle of orientation of the flap of the pool cleaner changes the extent to which the pool cleaner moves sideways while moving forwards or the extent to which the pool cleaner turns. | 05-26-2016 |
