An integral melter and pump assembly or system, and a method of making the same, is disclosed wherein the pump assembly comprises a melter housing having a melter container defined within the melter housing. A pump mounting plate is integrally mounted within a side wall portion of the melter container and an output dispensing supply pump is mounted directly upon an external surface portion of the pump mounting plate in a surface-to-surface manner such that heat generated internally within the melter container is effectively transferred by conduction from the melter container and through the pump mounting plate such that the temperature level of the output pump is elevated to, and maintained at, a predeterminedly desired level even when the pump, is not disposed in its output dispensing mode. In addition, since the output dispensing or material supply pump is disposed externally of the melter container and the melter housing, the output dispensing or material supply pump is easily and readily accessible in case maintenance becomes necessary. Optionally, an oil jacket or chamber can surround the melter container so as to more evenly or consistently provide heating of the melter container.

Embodiments provide a polymeric walkway for mitigating surface water runoff and a method for constructing the same. A polymeric walkway module is secured to a pre-conditioned ground. The polymeric walkway module includes an upper panel, a lower panel, and a plurality of spacers. The upper panel includes a plurality of perforations. The plurality of spacers is positioned between the upper panel and the lower panel defining a hollow space. Surface water permeates through the plurality of perforations and occupies the hollow space during the surface water runoff.

A method of manufacturing a catalytic sieve includes providing starting materials of an aggregate, a cementing agent, a sublimation agent and water. The sublimation agent (between 25% and 50% by weight of the cementing agent) is selected from molybdenum disulfide, tungsten disulfide, vanadium disulfide, copper sulfate, and combinations thereof. The aggregate contains at least 2% by weight of at least one transition metal. The method includes mixing the starting materials to achieve a mixture, placing the mixture into a form, and curing the mixture in the form to allow the mixture to become a solidified unit defined by a minimum dimension of thickness, length, width or diameter. The method further includes placing the solidified unit into a kiln, heating the kiln to 1115°−1350° C., maintaining the kiln at the temperature for between 10-60 minutes per centimeter of the minimum dimension, and removing the solidified unit from the kiln.

An attachment device for attachment to a pathway comprising a body having: a top surface for receiving foot traffic thereon; at least one point of flexure; and at least one arm extending from the point of flexure with the arm moveable about the point of flexure, the at least one arm configured to engage the pathway or a structural member of the pathway, wherein when engaged, the at least one arm secures the device to the pathway, wherein engagement of the at least one arm results in the device being compressively secured to the pathway in between two component members of the pathway.

A novel heat shielding material made of an inorganic material is proposed.

A heat shielding material made of an inorganic material, including: a base material; a underlayer layered on the base material; and a top layer layered on the underlayer, wherein the top layer has a thickness such that the underlayer is not visually recognizable, and transmits infrared rays, and the underlayer includes a commingled between a material of the underlayer and a material of the top layer, and a main reflection region where the material of the top layer is not present.

By a suitable combination of the top layer and the underlayer, a high solar reflectance (TSR) exceeding 30% can be obtained even at an L* of 40 or less.

Asphalt paving system and method involves the use of a primer, comprising hydrophobic microwave absorbing material mixed in a hydrophobic liquid, between an asphalt layer and a base layer below. The primer is configured to be deposited on the base layer at room temperature without preheating. Heating the hydrophobic microwave absorbing material, sandwiched between the asphalt and base layers, by microwave energy, allows for both effective de-icing of the asphalt pavement and for efficient repairs of the pavement, the latter by striping of the asphalt layer from the base layer.

A modular tile is disclosed configured to interlock with multiple tiles to form a modular floor covering over a floor. The tile includes improved grip and bounce characteristics. The tile may include an upper contact surface having rib with top edges that are sharp. Protrusions may extend from the upper contact surface to provide grip and increase ball bounce performance. The tile may be made of a composite of rigid plastic and rubber to improper bounce characteristics, including by increasing the degree to which the tile conforms with a subfloor.

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.
