  • Patent number: 10443250
    Abstract: A method for continuously extruding and depositing an unbroken layer of a slurry or mortar onto a selected work surface uses a mortar gun assembly with a chamber for receiving mortar from a remote supply hopper and an extruder configured to selectively apply a bead or ribbon of mortar of selected thickness onto the work surface. The user selectively applies mortar by controlling a rotating port valve between the hopper and the mortar gun chamber, and the rotating port valve provides a “rest state” in which the mortar is not sent to the mortar gun, but is instead re-circulated by the pump back to the hopper so un-dispensed mortar is kept moving and cannot dry or set.

  • Patent number: 10253978
    Abstract: A gas-air mixer assembly is described that helps mix fuel and air within an HVAC system. The mixer assembly can also achieve lower pressure drops than seen in other solutions. A mixer assembly can comprise a mixer body through which air is supplied. An orifice body can extend into the stream of air within the mixer body and then point upstream. A tip of the orifice body, disposed in the airstream, can provide fuel through one or more orifices. The flow of air around the orifice body helps to cause mixing, as does an elbow bend in the mixer body, downstream of the orifice body.

    Abstract: A steam generator having a channel for circulating heated fluid through a heat exchanger and having a channel for supplying water through the heat exchanger. The steam side of the heat exchanger is maintained at a pressure lower than the outside atmosphere and is heated by the heating fluid to a temperature more than the boiling point of the water at the lowered pressure. The water being introduced to the heat exchanger is heated to a boil. The steam produced is less than the boiling point of water in the atmosphere. A vacuum pump draws the steam from the heat exchanger and ejects the steam through a steam hose into atmospheric pressure. This rise in pressure is accompanied by a rise in temperature of the steam above the boiling point of water at atmospheric pressure.

  • Patent number: 8640972
    Abstract: A sprayer has a tank for holding a spray solution that is applied to a ground or turf surface. The sprayer includes an agitation system having a plurality of agitation nozzles that extend into the tank that are accessible from outside the tank and can be removed and replaced without using tools. The sprayer may include a rinse system carried onboard the sprayer which is segregated from the spray and agitation systems to avoid contaminating the rinse liquid prior to the time the rinse liquid is sprayed into the tank through rinse nozzles. The rinse nozzles include upwardly and downwardly directed nozzle ports and a bottom spinner for thoroughly cleaning all interior surfaces of the tank. The sprayer may also include a chemical eductor mounted on the side of the tank, whose weight is counterbalanced by springs, and which easily pivots between lower and upper positions on the tank.

  • Patent number: 8496188
    Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.

  • Publication number: 20130186977
    Abstract: A multi-container manual-pump-operated backpack sprayer including an open-topped backpack enclosure, a plurality (preferably three) modular liquid containers removably seated in the enclosure, a hand-lever-operated pump/accumulator combination, and a user-controllable manifold for selecting a particular chemical from the containers for administration through a spray wand. Chemical is carried to the pressure chamber by manually pumping. The pump draws liquid from a manifold-selected supply container outward through tubes to the manifold, which has a console of valves. Separate return tubes are provided for each chemical from the manifold back to the containers of origin, and the manifold allows convenient flushing of each chemical back to its container of origin. This ensures that chemicals are not mixed or cross-contaminated and avoids waste since all residual is returned back to its respective container. The manifold is conveniently carried at the hip for ease of access.

  • Patent number: 8132743
    Abstract: A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.

  • Patent number: 8128005
    Abstract: The invention relates to a fuel injector comprising an injector housing having a pressure chamber from which fuel subjected to a high pressure is injected into a combustion chamber of an internal combustion engine when the pressure in a control chamber expands into a pressure relief chamber by a control valve device. The aim of the invention is to create a fuel injector which has a long service life even though subjected to high pressures. To this end, the injector includes a low-pressure supply line which is connected to a low-pressure return line by a purge path extending through the pressure relief chamber.

  • Patent number: 8087596
    Abstract: The invention relates to a device (1) for metering media (2) and comprises at least one storage vessel (3), a measuring vessel (14) and a target vessel (14) that are interconnected to give one unit. By the exertion of force on the media (2) to be metered they can communicate between the storage vessel (3) and the measuring vessel (4) and can then be transferred to the target vessel (14). The metering volume is determined by the geometry of the measuring vessel (4). The target vessel (14) can be separated from the measuring vessel (4) by severing (welding, gluing, cutting) the connection between (14) and (4). The invention also relates to a method for metering media using the device (1) according to the invention. The device is suitable as a disposable unit and for the sterile metering of media in a non-sterile environment.
