Abstract: A mister for use with fans having blades protected by a guard wherein the mister is mounted on the guard and through a plurality of water atomizing nozzles projects a mist into the fan airflow to produce a cooling effect by the evaporation of the moist air. The mister may be used with original equipment fans, or may be retrofitted to existing guarded fans and economically produces a distribution of water particles within the airflow.

Abstract: An automotive, evaporative air conditioner having a unitary body, and a fixed, self-wetting water wicking assembly of a foraminous material which is self-wetting. The air conditioner is assembled by inserting wicking and filtering elements into the housing through the air inlet, allowing for use of a unitary housing.

Abstract: Process for the production of concrete tiles by cutting a block of concrete mixture, characterized in that the block of mixture is subjected to a preliminary curing at room temperature for a duration of at least 24 hours or to a low-pressure steam treatment at a temperature <100.degree. C. until the compression strength reaches a value of at least 20 MPa, and to a second treatment with steam in an autoclave. The cement tiles thus obtained may be bonded to the floor using a normal setting layer of cement mortar, without giving rise to any problems of detachment.

Abstract: The present invention relates to operation of residential or commercial evaporative coolers, more specifically, its subject matter is conservation of water needed to cool down ambient air in their operation.

Abstract: Sunscreen cover for an evaporative cooler includes a top and screen panels extending downwardly from the top to cover the sides of an evaporative cooler for protecting the evaporative cooler by providing shade for the cooler.

Abstract: A spreader plate having a water receiving area which receives water from a pump, a plurality of ribs radiating outwardly from the central water receiving area, the lengths and spacing of the ribs being such as to divide the water up into a plurality of streams of approximately equal intensity, and a cover over the water receiving area comprising a deflector which deflects water flow over the water receiving area in a constant thickness film and into the channels between the ribs.

Abstract: A shield to protect the exposed surface of the casing of an evaporative cooler from the heat loading effects of the environment is comprised of thermal insulation means coupled to the exposed surface of the cooler casing and a weather protective covering coupled to both the insulative means and the casing of the cooler so as to protect the thermal insulation means from the environment and maintain the invention in place, covering and protecting the selected surface of the cooling casing to be protected. In the embodiment disclosed, the surface selected for protection is the top surface of an evaporative cooler and the insulation material may be comprised of a polyfoam insulative board configured to conform to the top surface of the cooler. A protective covering is set down over the insulative board and affixed mechanically to the casing to prevent the cover from being inadvertently dislodged. The invention is especially adapted to be retrofit to existing evaporative cooler installations.

Abstract: A pliable plastic liner for the water sumps of evaporative coolers comprising at least a pair of interconnecting parts which fit together in a manner forming a water tight seal.

Abstract: The invention provides an evaporative airconditioner comprising a base, side panels and a top and wherein the side panels are supported on the base and have stiles having mitred side edges and wherein adjacent side panels abut and close sides of the airconditioner.A water trough for delivering to the side panels is also used and is an annulus of U-shaped section and is received in complementary formations in the upper ends of the side panels to stabilize those panels and be itself supported by the side panels.Clips may additionally secure the side panels together.The base may include a first platform for air blower means, a second perimetric, platform for the lower ends of the side panels, a perimetric flange to restrict outward movement of the side panels and a water sump.The top may include a perimetric flange to restrict outward movement of the tops of the panels.The airconditioner can have certain standard parts modified so as to be side, top or bottom delivery.
