Abstract: A humidifier device to prevent warping, cracking and shrinking of elements in stringed or other musical instruments subject to modification by reason of a lack of moisture in the instrument carrying case. The device comprises a small, sealed housing detachably securable to the interior of the instrument case and provides a refillable and leak-proof reservoir which feeds water or other evaporatable fluid to the top, bottom and inner peripheral side walls of an absorbent ring when the reservoir is filled to capacity; and when partially full and in any position of the carrying case water feed to the absorbent ring is maintained along at least one of the absorbent ring walls. A control ring is further provided which is rotatable about the housing to increase or decrease the evaporation rate of water from the housing ports communicating with the absorbent ring.

Abstract: A device for long-term evaporation of liquid perfumes, particularly for placing in the pockets of garments and handbags and equipped with a stand, comprising a flat, plate-like basic member which encloses a perfume carrier and which has at least one wall having an evaporation region made porous for evaporation purposes. The basic member is provided with a reserve perfume chamber which communicates with the evaporation chamber through at least one channel for the passage of perfume. A cover member is mounted on the basic member and movable thereon in the manner of a slide from a sealing position, in which the porous evaporation region is covered, to at least one evaporating position.

Abstract: A deodorant dispensing package having two rates of discharge of deodorant. The package is provided with air circulation ports for a low, continuous release of deodorant and a manual pump for a high, forced rate of deodorant discharge for sudden odors. The package is formed of two telescoping housing members with an internal wall portion that divides the housing into inner and outer compartments. The housing contains a deodorant reservoir and the inner and outer compartments are each provided with vent ports communicating externally of the housing. The inner and outer compartments also communicate through an interior port in the internal wall and a deodorant discharge surface is located in the inner compartment between the inner port and the inner compartment external vent port. Air circulation through the vent ports is sufficient to provide the low rate of air freshener activity. The manual contraction and expansion of the telescoping housing members provides a high rate of deodorant discharge.

Abstract: A rotary sprinkler is described comprising a nozzle formed with an axial bore, a spindle extending through the bore and including stops at its opposite ends, and a rotor floatingly mounted on the spindle for rotary and axial movement thereon by the liquid jet issuing from the nozzle bore, the spindle being also axially and laterally movable within the bore such that the rotation of the rotor by the jet self-centers it on the spindle and also self-centers the spindle in the nozzle bore.

Abstract: A fluid reflecting member for use in combination with a fluid spouting nozzle element, which member includes a cavity forming portion provided with a circular fluid reflecting cavity toward which a fluid or fluids is spouted from the fluid spouting nozzle element. The cavity forming portion is characterized by being provided with a plurality of axial slots having axially and outwardly inclining slot bottoms whereby a plurality of dispersing streams of the fluid or fluids passing through the axial slots is generated.

Abstract: A combined fragrance dispenser and humidifier includes a vessel to hold a quantity of water, an absorbent carrier member having one end in contact with the water and another end in air circulating relationship with a fragrance retaining member so that air circulates through the absorbent carrier member allowing the water vapor to evaporate while passing over the fragrance to dissipate the fragrance as well.

Abstract: An apparatus for generating bubbles in a liquid is disclosed which has a liquid spouting nozzle element for violently spouting a pressurized liquid, an impact disperser for generating a dispersion stream of the pressurized liquid directed into the liquid surrounding the impact disperser when the spouted pressurized liquid impinges upon the disperser and a gas supplier for supplying and guiding a stream of gas to a region surrounding the impact disperser thereby causing the gas stream to be dragged into the dispersion liquid stream. The gas dragged into the dispersion liquid stream is dispersed in the liquid and converted into fine bubbles.

Abstract: A method of generating mixed and atomized fluids is disclosed in which at least two fluids selected from gases, liquids and powders, are flown through a flow passageway including a first convergent and a subsequent divergent flowing zones, whereby the fluids are subjected to change in pressure, thereby being mixed and atomized. The mixed and atomized fluids are spouted from a second convergent flowing zone at a high speed toward a fluid reflecting means. The spouted mixed fluids collide with the fluid reflecting means and are further mixed with one another and further atomized when the mixed fluids are reflected from the fluid reflecting means. A fluid spouting composite nozzle unit for practicing the method is also disclosed in which a first nozzle has the first convergent flowing zone and the divergent flowing zone, and a second nozzle has the second convergent flowing zone. The fluid reflecting means is disposed on the downstream side of the spouting hole of the second nozzle.

Abstract: A deflector assembly for a spray gun includes a mounting collar and a pivotable deflector blade. The mounting collar has a plurality of locking tines, or fingers, for permanent snap engagement about a spray nozzle. The mounting collar further includes a support tube with a pivotable groove on an upper surface and a pair of locking detents on a lower surface. The mounting collar is rotatable about the spray nozzle. The deflector blade comprises a locking retainer having a pivotal shoulder of a complementary shape to that of the pivotal groove of the mounting collar. The deflecting blade further includes a camming or prong lock capable of interengaging with the locking detents on the mounting collar. The deflector blade includes a plate member extending from the locking retainer having a planar impact surface on one side and a serrated surface on the other.

Abstract: An insufflation nozzle, which has a plane of symmetry, includes a sleeve having an inlet which is symmetrical about an axis and an outlet orifice. A deflector is disposed to face the outlet orifice and extends transversely with respect to the axis. A link is provided between the deflector and the sleeve to permit movement of these components relative to one another. The link includes a screen disposed symmetrically with respect to the plane of symmetry. A surface of the deflector which is directed toward the sleeve has planar portions which are inclined relative to the axis and have a spacing, relative to the outlet orifice of the sleeve, which increases along a direction extending away from the screen.

Abstract: A combustion chamber for a gas turbine engine which has staged combustion in two toroidal vortices of opposite hand arranged one upstream of the other. A burner delivers air/fuel mixture in a radial direction to support the vortices and the burner has a convergent outlet for the air/fuel mixture.

Abstract: A spray nozzle unit including a deflector cone for dispersing sand slurry over a broad area of impounded clay slurry.

Abstract: An absorbent strip of material is carried for movement between a blocking position and a clearance position relative to the discharge of a valve actuator to provide for prolonged evaporative dispensing or direct dispensing of aerosol product, such as room deodorizer, to the atmosphere. The absorbent strip is carried in an annular groove defined by a plurality of vertical ribs on a carrier member, which is rotatable for movement into and out of alignment with the discharge outlet.
