Method And Device For Installing Synthetic Turf

Номер: US20120067996A1
Автор: David P. Motz, Joseph E. Motz
Принадлежит: Technology Licensing Corp

A method and device for installing synthetic turf uses a motorized turf rollout vehicle and a frame removably carried by the vehicle, the frame holding a roll of synthetic turf on a spindle at a first, forward end thereof. The roll and spindle are held in an orientation that is transverse to the first forward direction, and have a transverse dimension that extends beyond that of the vehicle. As the vehicle moves forward in the first direction, the vehicle engages and pulls the roll of turf, and the vehicle also moves on top of the just-unrolled portion of the turf. This accurately and efficiently places the turf on and over the base, in a desired position. Because the vehicle moves on top of the just unrolled section of turf, the present invention eliminates direct contact with, and disruption to, the underlying prepared base. This method and device reduces the time and cost associated with locating a roll of synthetic turf over a base during the installation of an athletic field, compared to prior installation methods.

Method for the adsorptive drying of purified biogas and for regenerating laden adsorbents

Номер: US20130000486A1
Автор: Lothar Guenther
Принадлежит: DGE Dr Ing Guenther Engineering GmbH

In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification.

A road patch for repair of potholes is disclosed. A pothole is preliminarily repaired with asphalt fill and compacted per current standard practice. Thereafter, a road patch is placed upon the compacted top surface of the asphalt fill, overlapping onto the adjacent road surface and compressed. The road patch forms a water proof seal over the surface area of the patch preventing water from seeping into the repaired pothole. The patch also resists crack propagation and minimizes the potential of asphalt chipping and the breaking down of the asphalt fill.

A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer. The turf cutter device is used prior to infill extraction, while the turf wind up device may be used before or after infill extraction, depending on whether infill extraction takes place at the field or at a remote site, respectively. 1. An apparatus for removing an infilled synthetic turf from a site comprising:a motorized vehicle;an extractor/collector located at a first end of the motorized vehicle, the extractor/collector further including an input section, an infill removal section, and an infill collector section;wherein the input section is adapted to direct a strip of infilled artificial turf up from a surface of the site and to the infill removal section as the motorized vehicle moves in a first direction, the infill removal section is adapted to invert the strip and to contact the inverted strip as the strip traverses the infill removal section so as to remove the infill therefrom and to thereafter redirect the strip toward the first end of the vehicle and eventually back onto the surface ahead of the vehicle, and the infill collector section is adapted to collect the infill removed from the strip; andthe ...

Pothole and utility cut repair overlay and method of installation

Номер: US20140017004A1
Автор: Timothy Geary
Принадлежит: GEARY TRUST

A road overlay product for protecting a repaired road portion including repaired potholes and utility cuts. A pothole or utility cut is preliminarily repaired with asphalt fill and compacted per current standard practice. Thereafter, the overlay is placed upon the compacted top surface of the asphalt fill, overlapping onto the adjacent road surface and compressed. The overlay forms a water proof seal preventing water from seeping into the repaired area. The overlay also resists crack propagation and minimizes the potential of asphalt chipping and the breaking down of the asphalt fill and surrounding roadway.

A self-propelled construction machine has a machine frame and an operating drum for processing the ground surface, wherein the operating drum is positioned in a downwards open drum housing, that is closed on both sides by an edge protector, which is adjustable in height by an actuator for raising and/or lowering the edge protector. A control unit comprises a sensor for registering the distance a between a reference point on the edge protector and the ground surface. Furthermore, the control unit is configured so that when the distance between reference point and ground surface falls below a predetermined minimum distance, the actuator is switched from a floating setting, so that the edge protector is raised. As a result, the edge protector tightly closes the drum housing at the sides without there being a risk that the edge protector can be entrenched in loose substrate.
