A module for use in constructing a pathway for traffic comprises a base member that defines a lateral groove disposed at its perimeter edge and extending along a first end, and a tongue structure disposed at its perimeter edge and extending along a second end. The tongue structure is received in the lateral groove and comprises a plurality of tongue portions that includes a first type of tongue portion and a second type of tongue portion disposed in alternating relation along the length of the tongue structure, to thereby define a throughpassage for receiving a securing rod. The first and second tongue portions have no vertical overlap one with the other. To form a pathway for traffic, the modules are placed in perimeter-edge to perimeter-edge relation, with the tongue structure of the modules inserted into the lateral groove of an adjacent module, and are secured together by the securing rod.

A pneumatic ball gathering system that clears tennis balls from a tennis court using air supplied to at least one discharge nozzle with optional intervening valves forming a structure that is typically disposed underground and selectively raised to clear balls. In one implementation, the structure is located along one side edge of the tennis court. In an alternate implementation, the structure may be located under the net and be configured with at least one nozzle disposed to direct air in both directions away from the net. A collection trough formed with a slope to cause collated balls to roll downward therein is disposed opposite the at least one nozzle. An optional mechanical conveyor system is placed in the trough to move collected balls to a predetermined location. A vertical conveyor raises balls for discharge into an appropriate container. The system may be used to facilitate drying the court after rain.

A system for regulating temperature and moisture on a field, while also absorbing an impact force from the field, uses adjacently joined panels positioned beneath the field, and that have sufficient thermal mass to transfer heat between an underlying fluid and the field. The temperature of the fluid regulates the temperature of the field, such that the field can be heated and cooled accordingly. The panels have water exfiltration and infiltration holes to drain moisture buildup from the field, and aeration channels for circulation. An interior region of each panel is defined by tube channels. The tube channel carries at least one fluid tube through the joined panels. The fluid tube carries a fluid having a predetermined temperature. The heat transfers between the fluid and the field through the plurality of panels. The temperature of the fluid can be adjusted to affect the temperature on the field.

A system designed to harness the natural energy of the sun and earth, by creating an energy exchange between the soil, using air as the medium. The medium, air, is also the desired product in its conditioned form. The energy exchanged in the system is in a harmonious relationship with season soil variation so as to produce constant air temperature regardless of season, or ambient air temperature.

The invention is concerned with an arrangement for preventing weather-induced formation of ice to a top surface (76) of an outdoor surface layer (74), comprising a heat conduit received in the surface layer (74). The heat conduit comprises a conduit (10, 12) for a circulating fluid adapted to emit heat to the surface layer (74) from a collector line (20, 22) adapted to receive heat from a volume (40) of water.

This application relates to a light-weight, multi-purpose construction module. The module may be used, for example, as a mold for settable materials such as concrete. A plurality of modules may be aligned together in different configurations for use as a temporary road or support for use on unstable terrain, such as arctic tundra or wetlands. In yet another application the module may be deployed as a storage or shelving unit. The module comprises a deck and a plurality of wall elements projecting from the deck and defining a plurality of honeycomb-like compartments. The module may be used in conjunction with a mating cover for enclosing the module compartments. In one embodiment the cover may be coupled to the module in two different orientations. In one of the orientations connectors may be coupled to an outer surface of the cover. The connectors are useful for joining separate modules together and for providing the assembly with enhanced structural integrity, for example to support heavy loads. In one embodiment heated water or other fluid may be circulated through the modules to regulate the temperature of construction panels formed from the modules, such as flooring or roofing panels.
摘要:
In accordance with the present invention, an apparatus for melting ice and snow which includes a pad means; a pump means; a heater means; a temperature regulation means; and a pump control means is disclosed. The pad means includes a top panel, a bottom panel and two end panels. The top panel has evenly spaced vertical integral channels which run the length of the pad means. The bottom panel has evenly spaced horizontal integral channels which run the width of the pad means. The vertical channels and the horizontal channels are in fluid communication with each other. The pad means is in fluid communication with the pump means and the heater means and is also in electrical communication with the temperature regulation means and the pump control means. The pump control means is in electrical communication with the pump means.
