The present invention provides new types of synthetic turf. The synthetic turf includes a pile fabric having a backing (1) and tufts (2) projecting therefrom. In one embodiment, at least a number of the tufts are made of a composite yarn formed by at least one fibrillated yarn (6) together with a number of individual filament yarns (7), in particular with so-called monofilament or monotape yarns. The fibrillated yarn and the individual filament yarns are preferably made of polyethylene so that the synthetic turf is sliding-friendly. In another embodiment, at least a number of the tufts are made of a composite yarn formed by monotape yarns twisted together with a number of the monofilament yarns. The monofilament and monotape yarns are preferably made of polyethylene so that the synthetic turf is sliding-friendly. The combination of a fibrillated yarn and individual filament yarns or the combination of monofilament and monotape yarns in a composite yarn allows immediate achievement of the look of natural grass, that is, without post-fibrillation, and avoids any visible difference in wear pattern between the different types of yarns. In another embodiment, the invention also provides improved particulate material for use as infill material for top-dressing a synthetic turf.

A propulsion linearizing mechanism is provided for linearizing a fluid flow. The mechanism includes a frame having a cylindrical outer baffle which rotatably supports a plurality of propeller elements thereon. Each propeller element defines a respective sweep area as the propeller element is rotated which overlaps sweep areas of adjacent propeller elements. The outer baffle circumscribes an outer periphery of the collective sweep areas of the respective propeller elements. The propeller elements rotate in the same direction whereby forces of curvature flow of adjacent propeller elements substantially cancel one another to linearize fluid flow through the mechanism. Additional baffles and infills within the areas of non blade sweep may be provided for particular applications of the mechanism. In various applications, linear forces of vector flow are formed by integrating curvature forces of tangential flow and economy flow systems are established to increase force potentials on the planes of rotating propellers to provide the emission and induction flow with an insulation whereby fluid in the immediate vicinity of the mobile flow remains in an undisturbed static state. This allows a fluid propulsion assembly to be fitted with an outer utility mantle in the static zone of the field.

A system for covering various types of ground where water and wind erosion protection are needed comprises a composite of at least one geotextile tufted or knitted with synthetic yarns (forming a synthetic turf), an open grid mesh, and a geo-filter (filter fabric). The filter fabric is positioned in direct contact with the ground surface, the open grid mesh is positioned over the filter fabric, and the synthetic turf is positioned over the open grid mesh. The system provides a beneficial erosion protection that does not require maintenance and can be used to cover slopes without requiring vegetative support and/or a topsoil layer. An optional sand layer can be placed atop the synthetic turf as desired as infill to ballast the material and protect the system against wind uplift.

In a seismic survey, idealized subsurface illumination is generated using idealized survey data. Then, the following three steps are performed during each of a sequence of time intervals during the seismic survey. First, an incremental portion of actual survey data is collected, using data acquisition equipment at a data acquisition location. Second, the incremental portion of actual survey data is communicated from the data acquisition location to a data processing location. Third, an incremental portion of actual subsurface illumination is generated using the incremental portions of actual survey data, to incrementally generate actual subsurface illumination at the data processing location. It is determined if additional data acquisition is desirable by comparison of the idealized subsurface illumination and the actual subsurface illumination, in the data processing location. Then, any desirable additional data acquisition is performed in the data acquisition location before the data acquisition equipment leaves the data acquisition location.
