| 20080253838 | Flood Wall - A portable, inflatable flood wall is characterized by a sheet of synthetic plastic material which is folded back on itself to define a chamber between bottom, rear and front portions of the sheet and within which at least one inflatable bladder is secured. When the bladder is inflated, the rear portion of the sheet is erected to a vertical position which prevents water from passing beyond the sheet. The front portion preferably contains a plurality of openings to allow water to enter the chamber. The weight of the water on the bottom portion of the sheet serves to hold the wall in place. A plurality of such walls may be connected in end-to-end relation to construct a wall of a desired length. | 10-16-2008 |
| 20080253839 | Machine for assembling silt fence - A machine which provides high quality, strong, relatively low-cost silt fencing in the proximity of the location of use of the produced silt fencing. It is within the scope of this invention to assemble material different from the material used for creation of “silt fencing”, which “fence” may be useful in different manner and be incorporated for different purpose than the purpose of silt fence. The machine basically is a simple machine having substantially four (4) sections: a front/input section which provides for the attachment of fabric and for the feeding or advancing of the fabric from a fabric roll onto and over a substantially flat and stake location surface; a stake attaching section where a first stake (to become the first drive stake) is attached, then following the advance or feed of 10 feet of fabric, a stake is attached to the fabric and a sequence of 10 stakes are attached creating an output roll of fencing substantially 100 feet in length; a fabric linear distance movement measuring section with automated start and stop of fabric feed at the set distance—for silt fencing this set distance is typically 10 feet—and following a 10 time sequence of automatic stake attachment, the feed does not start until a new first stake is attached and put onto the stake drive system; and a back/output section which provides for the automated power driven creation of a 100 foot roll of fencing. | 10-16-2008 |
