Abstract: A spray gun having a fluid flow control valve which is preferably located in a spray head. The flow control valve eliminates the need to change the spray head or fluid tip to change the flow rate in a suction feed and/or gravity feed paint spray gun when different materials are sprayed. The valve has a member which is rotatable over no greater than 3600.degree. and preferably over about 90.degree. for adjusting the flow rate. Calibration marks may be provided for setting the valve for flow rates produced by standard fluid discharge orifice sizes.

Abstract: Rechargeable containers and dispensers, in particular spray bottle dispensers including at least one chemical reservoir for recharging the spray bottle dispenser. Preferably, a plurality of separate chemical reservoirs containing chemical concentrate are provide within the spray bottle dispenser to fully contain any inadvertent spillage of chemicals, and to insure a high degree of safety against accidental spills, and/or accidental ingestion by children.

Abstract: A relatively efficient snowmaking gun which is of the compressed air and water type includes a water tube for receiving water from a source thereof under pressure and discharging the water in an annular diverging stream through an adjustable valve and a turbine which chops the water into fine droplets; and a central nucleator for receiving compressed air from a source thereof and for producing a central stream of fine ice particles downstream of the discharge end of the gun for mixing with the water to produce snow, temperature permitting. A preferred form of nucleator is an ultrasonic resonator for receiving air and water from sources thereof under pressure to produce an annular central stream of fine water droplets in air while creating ultrasonic waves downstream of the gun outlet. The gun can also include a casing defined by inner and outer shells surrounding the water tube and forming an air chamber which receives compressed air for discharge through a plurality of spaced apart nozzles.

Abstract: A cartridge (2) secured for angular movement on the handset head (10) has a valve-like cooperation with openings (12) in the head (10) for water flow via passageways (20, 21, 22) in the cartridge (2) to showering outlets (30, 31, 32) on appropriate rotational setting of the cartridge (2). Cleaning pins (7) rotatable with the cartridge (2) and co-axially movable relative to it are operated by a cam track (8, 81) to penetrate fine spray outlets (32) to clean them of scale. The cam co-action of the pin ring followers (71) with the track (8) causes the pins (7) to remain inoperative during the showering modes but the pins (7) are operated for penetration by further turning of the cartridge (2) i.e. independently of the showering modes. The followers (71) are spring urged against the track (8) such as by resilient blades (75) bearing against the taper periphery (27) of the cartridge (2). Clearance pin penetration of the outlets (32) permits water flow to wash away scale and minimize back pressure.

Abstract: A view tank including an upper partition plate and a lower partition plate dividing the tank body into an upper section, a middle section, and a lower section. The walls of the middle section are transparent and openable for planting purposes. The lower section is a water storage section, and water is pumped to a fog generating box for generating fog. Excessive water flows down from the upper portion of the middle section. The upper section has a light for illuminating the middle section, and a fan for blowing the hot air in the upper and middle sections to the outer rim of the transparent walls of the middle section so as to remove water moisture on the walls. The respective walls of the three sections may be fabricated into integral units which are then assembled as a whole.

Abstract: An injector nozzle has a body having a nozzle through which fuel is delivered. The nozzle includes a port having an internal surface and a valve member having a complementary external surface. The valve member is movable relative to the port to respectively provide a passage between the surfaces for delivery of fuel in the form of a spray or sealed contact therebetween to prevent the delivery of fluid. A fluid flow control body is located beyond an extremity of the nozzle body corresponding to the location of the port. The control body has a control surface configured and positioned such that the fuel spray established by fluid issuing from the port will follow a path determined at least in part by that control surface. The flow control body is in part hollow.

Abstract: An agricultural spray implement includes a plurality of removable valve/filter/nozzle cartridges. Each removable cartridge has a single housing that retains a magnetized filter, a high speed solenoid valve, and a spray nozzle. In the event the system filter of the spray implement is removed, fine particles which otherwise might clog the solenoid valves are stopped from entering the solenoid valves by the magnetized filters of the valve/filter/nozzle cartridges. Each cartridge has a clean-out purge valve so that its magnetized filter can be unclogged without removal of the magnetized filter from the cartridge housing. A light emitting diode of the cartridge provides a visual indication that the cartridge is dispensing agricultural liquid. The light emitting diode is turned on when the solenoid valve is controlled to be open.

Abstract: A garden hose nozzle is composed of a cylindrical housing, a toothed disk, a shaft member and a fastening bolt. The fastening bolt is used to fasten the tooth disk and the shaft member in the stepped axial hole of the cylindrical housing. The shaft member can be rotated manually such that the interstices of various sizes are formed between a tapered ring edge of the stepped axial hole of the cylindrical housing and the tapered portion of the shaft member for regulating the sprinkling pattern of water.

Abstract: A plural component airless spray gun for reactive liquid materials has a mix chamber into which coreactive liquid components are introduced and mixed, an airless tip at a forward outlet from the chamber from which the mixed components are emitted in a fan-shaped spray, and a mechanically operated purge rod for cleaning residual reactants from the mix chamber and airless tip. The purge rod has a main body of a diameter slightly less than that of the mix chamber and a probe at its forward end that geometrically conforms to and is adapted to enter into and clean the inside of the spray tip. During spraying the purge rod is retracted in the mix chamber rearwardly of liquid reactant inlets to the chamber. Upon completion of spraying or periodically as desired, the purge rod is moved forwardly to clean the mix chamber and the inside of the airless tip of residual reactive components.

Abstract: A drip irrigation emitter defining a flow control passageway having an inlet to communicate with a supply of pressurized water, and an outlet to communicate with a water discharge opening, includes an obstruction formation between the flow control passageway outlet and the water discharge opening effective to produce a relatively small obstruction to the flow in the direction from the flow control passageway outlet to the water discharge opening, and a relatively large obstruction to the flow in the reverse direction such as to reduce the possibility of the entry of external solid particles into the emitter via the water discharge opening.

Abstract: A regulated flow-restrictor device particularly useful as a drip irrigation emitter includes an elastomeric element constructed and supported such that it is non-uniformly deformable along its length in response to an increase in fluid pressure to effect a sequential closing of clearances in the flow-reducing passageway.

Abstract: A bag-in-carton 1 comprises a substantially rectangular parallelepiped carton 2, an inner bag 3 and a pouring spout 5 attached to an inclined panel of the carton 2. The inner bag 3 is adhered to inner-bag adhering regions 9 provided on the substantially entire parts of the inside surfaces of the inclined panel 2g, a pair of side panels 2b, 2d which are adjacent to the inclined panel 2g, and a side panel 2a. The inner bag 3 is also adhered partially to the inside surface of a side panel 2c which is remote from the incline panel 2g. When a content is drawn out through the pouring spout 5, the inner bag 3 is gradually released from the inside surface of the side panel 2 of the inside surface of the carton 2 and is deformed, moved to the pouring spout 5.

Abstract: An irrigation spray head includes a plurality of orifices each for directing irrigation water in a substantially continuous stream to an impact location within an area around the spray head to be irrigated. Each orifice has associated with it a mechanism for adjusting the flow area and thereby adjusting the flow rate through the orifice and the distance between the spray head and the impact location associated with the respective orifice. Each substantially continuous discrete stream emitted through one of the orifices is at a flow rate higher than the local hydraulic loading rate associated with the soil in the respective impact location. Thus, each stream of water from the spray head produces localized runoff and a wide wetting pattern around each impact location. The flow rate for each stream is chosen so that the wetting pattern associated with each impact location combines with the other wetting patterns to substantially cover the entire area to be irrigated.

Abstract: There is disclosed an airless spray head having a rotatable turret orifice tip holder with a floating turret seal preloaded with a compression spring within a spray head body having a distal circular rim, a through longitudinal passageway and an intersecting orthogonal bore which receives the cylindrical turret. A retainer nut surrounds and receives the spray head body which is captured by the circular rim, and a low friction washer is located between the rim and the retainer nut. The compression spring is biased against the upstream face of the turret seal by a spring retainer with a boss on its downstream face and an annular groove on its upstream face in which an annular sealing washer is permanently received. The compression spring is mounted on the downstream boss and retained thereon by spring detents of the boss. A second annular sealing washer is located between the downstream face of the retainer and the end of the spray head body.

Abstract: The invention relates to a differential pressure cleaning system consisting of a flow pipe (7) with a throttle (1) and at least one cleaning fluid feed device (14) fitted over the throttle (1) for treating exhaust gases from technical processes which give off mixtures of gases, vapors and dusts. The throttle (1) located in the flow pipe (7) takes the form of an approximately rectangular slot (2) at its narrowest point. A displacement body (3) is arranged downstream of the slot (2), extending over the entire length of the slot and mounted in such a way as to be movable towards and away from the slot (2). This provides two roughly parallel venturi grooves (6) between the walls of the throttle (1) and the outer wall of the displacement body. The cross-sections of these two venturi grooves (6) can be adjusted as desired by moving the displacement body (3). The throttle (1) in the flow pipe (7) is preferably realised by two commercially available transverse pipes (8) displaying a circular cross-section.

Abstract: A spray assembly including a venturi type spray nozzle, a valve attached to the spray nozzle, a reservoir adapter that can engage a reservoir containing a liquid coating material to be sprayed, and a flexible hose between tile reservoir adapter and the valve. The outer surface texture of material being coated can be adjusted using the valve which is useful in matching the surface texture of chip resistant coatings and undercoatings on an automobile, and the hose allows the operator to spray material onto a substrate from any orientation of the spray nozzle which facilitates coating locations such as the lower portions of panels or in wheel wells and trunks. A valve passageways is shaped to facilitate fine adjustment of the air/coating material ratio when small amounts of material are being delivered, and the valve includes an air purge to remove material from the valve and nozzle when the valve is shut off.

Abstract: An aerosol dispensing apparatus comprises a housing which includes a top l having a sharp edged orifice and a speaker assembly mounted on a bottom portion of the housing. A sawtooth waveform generator generates and then provides a sawtooth waveform signal which includes a jitter component to the speaker assembly which drives a flexible diaphragm resulting in a reciprocating motion of the flexible diaphragm. The ramp portion of sawtooth waveform signal retracts the flexible diaphragm in a rearward direction, while the approximately vertical portion of the signal causes an abrupt forward movement of the flexible diaphragm. The inner portion of the housing forms a chamber which contains a medication. The jitter component of the sawtooth waveform signal fluidizes the medication suspending the medication in air within the chamber to form a vaporized medication.

Abstract: A fan pattern nozzle has an inlet groove on its inlet surface along a radius to a single edge of its perimeter. The water enters the orifice via this inlet groove. The water picks up a momentum which results in an exit deflection angle of about 15.degree. out the outlet groove. This nozzle enables the construction of an injection molded unibody washing cylinder having a maximum wall thickness of 1/4 inch. A plurality of nozzle mounting holes are canted at 15.degree. down toward the bottom of the washing cylinder. When the nozzles are installed in the mounting holes, the resulting fan patterns are canted 30.degree. toward the bottom of the washing cylinder, thereby improving the cleansing operation and minimizing the splashout. Washing embodiments include hand and glove, small parts, feet, whole body and cars.
