20090136296Method for assembling cobblestones into mats and device for carrying out thereof - A cobblestone mat usable for covering roads, sidewalks, patios, outside/inside walls, etc., is disclosed, comprising a plurality of predeterminedly shaped cobblestones disposed at a certain distance to each other and a binding net internally imparted into and joining the cobblestones. A method is provided for assembling concrete cobblestones and the net, comprising the steps of providing a mold for forming the mat, predeterminedly placing the net into the mold, pouring liquid concrete into therein, hardening the concrete, forming the mat, and extracting the mat from the mold. An automated device for making the mat is proposed. There are also described preferable shapes and sizes of the cobblestones and cobblestone mats. The invention permits achieving high quality covering even by low-experienced workers, expediting the covering, minimizing dust and noise at work site since it avoids cutting the cobblestones, decorating surfaces with imitation of natural stone appearance and various colors and designs.05-28-2009

20080205985Fascines - Inflatable members for forming fascines for filling ditches or smoothing other discontinuities in or on the ground to facilitate the passage of vehicles across the discontinuity are normally carried uninflated in a package at one side of a vehicle such as a tank. The package can be moved from that stowed position to an operational position at the front of the vehicle, for example by swinging around a pivot located at the front corner of the vehicle, from which position the fascine members can be released and inflated. In this way there is no need for the vehicle to turn side on to the discontinuity in order to deploy the fascine.08-28-2008
