Patent number: 5417929Abstract: A device (20) mounted on the exterior of, and communicating with the interior of, plenum (19) or output ducts (18), of an existing air conditioning and heating system of an enclosed structure, to combine the elements of air, and the elements of a scent producing, disinfecting, or germacidal chemical, utilizing, and upstream of, the air currents produced by the fan in the system to distribute the elements mixture at the outlets of output ducts (18) into the areas they serve. The amount of mixture flow, determined by the user, is controlled by manual manipulation of ball valve (23). The frequency of the mixture flow, determined by the user, is controlled either by the automatic cycling of the system fan, or, by manual manipulation of the fan switch on the system control.Type: GrantFiled: November 29, 1993Date of Patent: May 23, 1995Inventor: Stanley F.

Patent number: 5301873Abstract: A low fluid indicator for a fluid injection system of the type having a sealed pressurized canister, and a valve responsive to a control signal to release fluid from the canister includes a counter that maintains a count. A pulse generating circuit increments the count by a first increment and a second increment in response to the control signal. The first increment is insensitive to the duration of the control signal above a threshold duration and is selected in accordance with a fill volume of the injection system. The second increment varies with duration of the control signal above the threshold duration and has a count rate selected in accordance with an injection flow rate of the injection system. A low fluid indicator lamp is responsive to the counter to indicator a low fluid condition when in the canister when the count exceeds a selected value.Type: GrantFiled: June 25, 1992Date of Patent: April 12, 1994Assignee: Kold Ban InternationalInventors: James O. Burke, Dean R. Solberg

Patent number: 5146762Abstract: An evaporative cooling system for buildings comprising means to draw air from the building, air ingress means having air permeable pads in an opening in the building, and water supply means to supply water to fogger nozzles which direct a water vapor fog toward the external surface of the pads, thus cooling the air drawn through the pads. The fogger nozzles are connected to interconnected water conduits, one of which is independently operated from the others such that it will only operate in cases of extreme temperature, to insure that the pads will not be oversaturated. Preferably, the water conduits are controlled by a thermostat responsive to the internal building temperature, while the independent conduit is controlled by a second thermostat responsive to the external ambient temperature.Type: GrantFiled: November 21, 1991Date of Patent: September 15, 1992Inventor: Robert C. Atkins

Patent number: 5079934Abstract: The cooler apparatus includes evaporative elements which are liquid absorbent plates formed of compressed fibers defining capillary channels and pores, for drawing up water within the plates and evaporating the liquid from the surface of the plates, with a plurality of absorbent plates and contacting adjacent plates, the spacing between adjacent plates being thereby determined by the thickness of the spacer members. Another currently preferred aspect of the invention a mechanism for providing the evaporative liquid to at least an upper portion of the plurality of plates, so that this portion which typically dries out can remain uniformly wetted, to thereby prolong the life and efficiency of the absorbent plates.Type: GrantFiled: November 19, 1990Date of Patent: January 14, 1992Inventor: Lev Vinokurov
