  • Patent number: 5433764
    Abstract: A filter consisting of a conventional filter medium mounted between retaining layers of a porous fabric cut to fit the shape of the opening in the mechanism in which it is to be mounted. A tab extends from one edge of the filter. Around the outer periphery of one of the retaining layers is a layer of adhesive which is, in turn, covered by a protective layer of paper, cardboard or the like. Upon removal of the protective layer, the filter is held in place by the layer of adhesive against its mounting. The protective paper is left on a portion of the tab, thereby, reinforcing the tab and allows it to remain free to manipulate the filter assembly during installation and removal.

  • Patent number: 5429650
    Abstract: A smoke stack, which discharges contaminated gases, is provided with a plenum chamber, at its end, formed of one or more stacked modules. Each module includes a hollow cylindrical housing, from which protrudes, in various radial directions, a plurality of ducts, each being provided with a nozzle at its end. The nozzle has a central passageway through which a portion of the gases pass and is discharged into the atmosphere, and a second passageway which directs the air around the discharging gases for imparting a swirling action to the commingled gases. An ultra low volume of treatment fluid, usually a liquid chemical, is progressively discharged into the central passageway so that fog is generated as the gases and liquid emerge. Relief valves for the gas discharge into this fog. An accumulator tank at the top of a chamber or a metering pump supplies the liquid.

  • Patent number: 5422045
    Abstract: Apparatus which accelerates the cooling of the stored water cooled in the storage tank after a refilling operation so that it corresponds to the temperature that is normally reached after a relatively long water storage period. The apparatus includes a carbonator tank having at least one spray opening in the water feed line leading into the head-space region of the carbonator storage tank and where the spay opening is directed to the side walls of the tank in the vicinity of an ice bank formed on an upper inner wall surface thereof. An additional spray opening is oriented so that it points directly at the water surface and by a relatively simple valving arrangement both downward and/or lateral sprays can be implemented.

  • Patent number: 5422043
    Abstract: A diffuser for dispersing gas bubbles into a liquid is formed of gas permeable material having a high surface tension at an interface with the liquid and a low surface tension in a region inward from the interface. The upstream region with the low surface tension resists liquid backflow, and the high surface tension of the interface keeps the bubbles small as they depart from the diffuser and enter the liquid.

  • Patent number: 5413742
    Abstract: A post-mix beverage preparation and dispensing unit includes a carbonator tank coupled to a feed water branching circuit. The branching circuit selectively feeds fresh water from a pressurized fresh water source to the storage tank where the water is mixed with CO.sub.2 gas and is fed to a concentrate mixing station or it feeds fresh water through a heat exchanger which is coupled to the cooled carbonated water of the carbonator tank to cool a supply of fresh water which is then delivered to the same mixing station along with the proper concentrate of the proper amount. A selected beverage is delivered to a dispensing station and can either be a carbonated beverage or a non-carbonated beverage depending on the desire of the consumer.

  • Patent number: 5413741
    Abstract: A plurality of corrugated plates are arranged in parallel relationship with corrugations in adjacent plates extending in a criss-crossing pattern to form a packing element for a heat exchange or mass transfer column. The plates are spaced closer together by providing reliefs in adjacent plates at the points of intersection between the criss-crossing corrugations. The reliefs allow the corrugations on the adjacent plates to extend into each other to reduce the spacing between the plates. The reliefs may be in the form of apertures or recesses.

  • Patent number: 5407607
    Abstract: A device for enhancing contact between a first fluid having a predominant direction of flow and a second fluid, comprises a layer of material generally disposed in a plane that is aligned with the direction of flow. The layer has a plurality of rows of corrugations projecting out of the plane for deflecting the fluids. Each row of corrugations is arranged in a diagonal with respect to the direction of flow so that an elongated vertex of each corrugation in said row is offset from the elongated vertex of an adjacent corrugation in the row with respect to the diagonal. Among other advantages, the offset, diagonally adjacent vertices are highly effective in interrupting the liquid and vapor flows, thereby improving mixing efficiency while also decreasing vapor pressure drop and increasing flow throughput.

  • Patent number: 5407604
    Abstract: A humidifier that can be used on a forced air circulation system for injecting atomized liquid into the cold air portion of that forced air circulation system includes a neubilizer for atomizing water fed thereto. The humidifier can be used in conjunction with an air cooling system and includes a demineralizing filter for removing white dust before the water reaches the humidifier. The filter can take various forms and can include several elements. One form of the humidifier can be connected between a hot air plenum and a cold air plenum of the forced air circulation system whereby the pressure drop between these two plenums is used to move moisture entrained air into the cold air plenum.

  • Patent number: 5407606
    Abstract: Apparatus useful for heat exchange by evaporative cooling when employed in conjunction with a conventional cooling tower. The arrangement includes a header pipe which is used to divert a portion of the water in the cooling tower supply conduit up stream of the cooling tower to a multiplicity of vertical pipes and spray nozzles which are evenly spaced external to the cooling tower so as to produce a uniform spray pattern oriented toward the central axis of the cooling tower and thereby induce an air flow into the cooling tower which is greater than otherwise achieved. By spraying the water to be cooled towards the cooling tower in a region external to the cooling tower in a manner such that the spray falls just short of the cooling tower basin, the spray does not interfere with the operation of the cooling tower, proper, and the-maximum increase in air velocity is achieved just above the cooling tower basin where it is most effective.
