Abstract:
This invention relates in general to a fluid device and to a method of changing the aperture size of an orifice aperture. The invention relates in particular to a technique capable of easily forming an orifice aperture having an exact aperture size and easily making a change in the orifice aperture size. While being brought into communication with a connecting pipe 83 through an intersecting inner aperture 633 drilled in a lower plate 63 of a device main body 6, two inner apertures 632, 632 with their one ends opening to a recessed portion 631 are each provided with a female thread 634. An orifice member 4 provide with a through-hole 412 having a corresponding inside diameter to an orifice aperture and communicating with a hexagon socket into which a hexagon bar spanner wrench 16 is internally fit, is threaded into each female thread 634, whereby the orifice member 4 is mounted. Finally, a covering member 15 is sealingly threaded into an opening of the other end of each inner aperture. Air supplied from the connecting pipe passes through the through-hole 412 serving as the orifice aperture and is blown into oil stored within the recessed portion from an end opening 413. If replacement orifice members with respective through-holes having different inside diameters are prepared, this makes it possible to make a change in the orifice aperture size by replacing the existing orifice member with a replacement orifice member.
Abstract:
An apparatus for preventing the drying of at least one nozzle of a fluid dispensing device includes an element providing moist gas, a supply hose for moist gas and a gas controller which forms a space around the nozzle. Moist gas is led into the space around the nozzle from the elements providing gas through the supply hose. Moist gas leaking out of the space is replaced by new moist gas led into the space.
Abstract:
A fluid spray is provided by apparatus (12) which includes jet spray (13) means for producing at least two jets of fluid (10,11). The jets of fluid at least partially intersect to thereby provide a predetermined spray pattern of fluid, preferably fan shaped. The jets of fluid (10,11), from nozzles, can be directed towards a vehicle windscreen or headlamp.
Abstract:
A method of controlling irrigation to an irrigated area comprises: extrapolating an irrigation schedule at least partly as a function of at least two user entered data points; and executing the irrigation schedule by an irrigation controller. The user entered data points can all be entered at the same time or over a period of time. Furthermore, two or more user entered data points may be entered for the same date. Additionally, the user entered data points may be deleted. A warning is preferably displayed to the user (a) when a user-entered data point is projected to result in an irrigated area not receiving adequate water to meet a plant's water requirement, or (b) when an irrigated area is projected to receive excessive water.
Abstract:
The present invention provides a spray delivery system and methods of use thereof, suitable for delivering a fan-shaped vaccine spray to birds or chicks held within an open-topped container, comprising a cover, an elongated guide rail mounted thereon, and a spray head may move reversibly on the guide rail. The spray head comprises a spray nozzle assembly having a spray port and optionally a fan-shaped nozzle for delivering a fan-shaped fluid spray. The cover has an elongated slot that permits the spray nozzle assembly to extend below the plane of the cover, while allowing the spray nozzle assembly freely traverse the length of an open-topped container placed beneath the cover. By reversibly moving the spray head along the guide rail, the spray delivery system can deliver a substantially uniform fluid spray to an open-topped container with minimal overspray and reduced fluid wastage.
Abstract:
The invention intends to prevent the occurrence of a phenomenon that air is sucked through an ejection port formed at a nozzle end when a plunger rod is retracted to move away from a valve seat. In a method or apparatus for ejecting liquid droplets in which a liquid under regulated pressure, the liquid being stored in a container as required, is ejected while it is caused to fly in the form of liquid droplets from a valve ejection port, bubbles are prevented from being mixed into the liquid through the ejection port by controlling a supply amount of the liquid in a manner being able to follow a pressure difference between the ejection port and a flow passage in a valve body. The liquid is continuously ejected at a high-speed tact. The ejection port is opened with a plunger rod retracted by air pressure, and the liquid droplet is ejected through the ejection port with the plunger rod advanced by a resilient force of a spring. Bubbles are prevented from mixed in the liquid through the ejection port upon retraction of the plunger rod by controlling a retraction speed of the plunger rod in accordance with an air flow rate.
Abstract:
A piezoelectric atomizer (10) has a horizontal support (14) with an opening (16). Mounting posts are formed to extend up from the horizontal support alongside the opening (16). A wire support 26 extends from an atomizing assembly (24) to the mounting posts and the ends of the wire support are wound around two of the mounting posts.
Abstract:
A method for producing or neutralising scents by means of fragrances being contained in a liquid medium substantially comprising three steps. Collision of fluids containing fragrances under high pressure from a suitable nozzle into a downstream reactor thereby producing an aerosol cloud. Providing means of transporting the aerosol cloud out of the reactor area and transporting the aerosol out of the reactor area. According to a preferred embodiment of said method energy is provided in the downstream reactor so that a further diffusion of the aerosol occurs after leaving the nozzle. Moreover: A suitable device for performing said method which particularly comprises a micro electromechanical element for supplying the fragrances in the reactor, and which comprises furthermore said means of transporting the aerosol out of the reactor; and according to a preferred embodiment said device further comprises a suitable power generator for providing the power for the retreatment of the fragrances in the reactor area.
Abstract:
A method for controlling the supply of liquid to an aerosol generator comprises operating a liquid supply system to supply a liquid to a vibratable aperture plate of an aerosol generator which senses an amount of liquid adhering to the vibratable aperture plate, and controls operation of the liquid supply system to adjust the amount of liquid adhering to the vibratable aperture plate.
Abstract:
The fire suppression device is based on installing a cannister of a fire extinguishing composition on a gas barbecue. Tubes from the cannister direct the fire extinguishing foam or composition to flames that may shoot out from the Venturi tubes or the burners or the cooking surface.
