Abstract: A pulsating spray head is provided for attachment to a source of fluid under pressure, e.g. water, which is of simple construction and provides for effective pulsations. The head comprises a housing in which is mounted a body portion which is closed off by a primary plate having a plurality of rows of radially extending perforations. A pulse disc is retained within the body portion and has a conical face resting on the primary plate. Fluid flow through the body portion causes the disc to roll around on the primary plate and sequentially block the rows of perforations in the primary plate whereby pressure fluctuations are caused in fluid exiting the primary plate. In a preferred embodiment, an orifice plate is secured in spaced relation to the primary plate to form at least one pressure chamber therebetween.

Abstract: There is disclosed an oscillating reed particularly for use in generating a sweeping or oscillating air flow pattern which is rendered clickless by limiting directions of bending of the reed element to an axis transverse to the direction of air flow. This significantly silences the oscillations and, in conjunction with polishing of the edges of the reed and rounding the corners of the mounting bar in which the downstream end of the reed is secured, cracking and breakage of the reed element has been substantially eliminated thereby lengthening significantly the life of the oscillating element.

Abstract: A shower device attachable by suction cups to a wall, such as adjacent a bath tub; the device including a panel supporting a row of adjustable shower heads to each of which water is supplied that is selectively mixed with diluted soap from a soap dispenser mounted on the panel, a pulsator being selectively used to pulsate the sprayed water, and a flexible hose from the device for connection to a water supply faucet valve.

Abstract: A swivelling fan-jet sprinkler which is convertible from a coarse sprinkling mode in which it covers a relatively large irrigation area to a gentler spraying mode in which it covers a smaller area, the conversion being achieved by means of a removable spinner cage which surrounds the nozzle cylinder of the sprinkler. The spinner cage has a captive snap ring cooperating with a groove in the nozzle cylinder to produce a detent action for attachment and removal of the spinner cage. The latter is driven by the water jets which are disturbed in the process.

Abstract: A pulsating device is disclosed herein for interrupting the flow of water being discharged via a nozzle carried on a dental syringe. The device includes a body coupled between the syringe and the nozzle having a central cavity partially occupied by a flutter valve. The valve includes a broad, flat member pivotally carried at its mid-section in the cavity so as to interfere with a flow of water passing through the cavity from the syringe to the nozzle. One end of the member is weighted so that the member flutters across the ports of the syringe and the nozzle to interrupt the water flow in response to the incoming water pressure from the syringe.

Abstract: A device for producing solid aluminum chloride from gas containing gaseous aluminum chloride by means of a fluidized bed condenser. Between the inlet pipe for carrier gas and an outlet pipe for residual or waste gas there is a distributor plate with openings in the form of nozzles, at least one cooling facility, a feeding facility for the supply of gas containing gaseous aluminum chloride and a facility for drawing off the solid aluminum chloride. The outlet pipe for waste or residual gas is connected to the inlet pipe for carrier gas via a separator which separates out fine particulate aluminum chloride, which is then fed back to the bed to act as nuclei.

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 rotary atomizer suitable for spraying crops with liquid is driven by the liquid itself. The atomizer comprises a hollow, truncated cone, a central axial shaft extending through the interior of the cone, a liquid jet driven turbine on the shaft, and an opening in the turbine so that liquid flows from the turbine to the interior of the cone.The liquid may be used at pressure of 0.7 to 10 bars gauge and feed rates of 10 to 1,000 ml/min, with the rate of feed being equal to the rate of discharge so that there is no liquid recycle.

Abstract: A shower spray head for providing a fluid spray with mechanical vibration of a part of the spray head, comprises, in combination, a fluid flow for delivering a shower spray; a turbine mounted in the path and drivable in rotation about an axis by fluid flow through the path; an eccentric rotatable form mounted for rotation about the axis and drivable by the turbine and eccentrically mounted with respect to the axis; and a vibratory housing connected by a pivotal connection to the eccentric form whereby rotation of the turbine during use causes vibration of the vibratory housing.

Abstract: A shower head that employs a rotor for effecting a pulsed jet-discharge is embodied in a construction by means of which the user may selectively secure either a pulsed jet-discharge or continuous spray discharge from the shower head. The rotor is housed between upstream and downstream housing parts that are axially movable between pulsed discharge and spray discharge positions, by relative rotation of said upstream and downstream housing parts through a screw-threaded connection so that the user's selection between pulsed jet-discharge and continuous spray is achieved by a simple rotary motion of the downstream housing part. A selectively releasable stop member limits rotation in one direction to insure proper axial spacing of said upstream and downstream housing parts when pulsed jet-discharge is selected.

Abstract: A pulsating spray nozzle has a number of features including the introduction into the outer periphery of a forced vortex of a speed-control fluid. In such a forced-vortex environment, a floating turbine is enabled by means of paths correlated with outlet openings better to avoid stalling. Improved dimensioning of elements in the forced-vortex-turbine approach also contributes in that direction. A regulator limits the rate of flow of fluid through the device to a predetermined maximum amount upon increase of incoming water pressure beyond a selectable level.

Abstract: The present invention relates generally to a hand held shower spray apparatus, and more particularly, to a hand held shower spray apparatus including a metering device to adjust the flow rate of water therethrough and apparatus which is selectively adjustable to provide a pulsating spray, a normal spray or a combination thereof.

Abstract: A conduit is traversed by a screw, which screw may or may not be capable of rotating within the conduit, the screw alone, or the screw together with the conduit, become rotatable around their common axis when fluid under pressure enters from one end of the conduit, exits from the other by traversing the helical path of the screw. The construction in which the screw is rotatable within the conduit is found suitable for producing a pulsating stream of water and for building showerheads for selectively producing different types of streams, such as (a) pulsating stream, (b) spray, and (c) soft bubbly aerated stream. Various valves manually operated by a part of the showerhead perform the selection. The pulsating stream is achieved by a screw having helical threads that makes a snug fit with the inside wall of a cylindrical pipe through which the water flows; the flow rotating the screw which in turn operates a valve that at least partially interrupts the flow of water through an outlet orifice.

Abstract: A pulsating water jet massage shower head comprises a shower head housing which has an interior chamber which opens outwardly. A nozzle member comprising a flat plate nozzle portion in a cylindrical fitted portion is fitted into the chamber of the housing and it is provided with a plurality of nozzle bores which extend through hollow cylindrical pin portions which extend upwardly from the interior surface of the plate portion. A cover member is arranged in the housing chamber spaced inwardly from the nozzle member and it has a segmental closing disk portion which acts to deflect water which is delivered through connecting conduits in the housing so as to cause rotation of a valve rotor positioned between the cover member and the nozzle member. The deflection and the rotation of the valve rotor produce rotating water jets through the nozzle bores.

Abstract: A selectively-controlled pulsating water shower head comprises a housing including a spray block formed with a central chamber having a first group of openings for outletting a continuous spray, and an annular chamber therearound having a second group of outlet openings. A plurality of freely movable members, in the form of curved segments, are drivable around the annular chamber by the water inletted into the housing for outletting the water through the second group of openings in the form of a pulsating spray. The shower head further includes a manually-controlled diverter having a displaceable stem assembly for selectively enabling either the continuous spray or the pulsating spray.

Abstract: A showerhead having an axially shiftable valve means to deliver either a continuous steady water spray or an intermittent or pulsating water spray. The head has a peripheral chamber through which water flows to provide the continuous steady shower spray and an inner chamber through which the water flows to provide the pulsating shower spray. The valve means travels only 0.200 inch in shifting from the pulsating spray position to the continuous spray position. In the pulsating spray position, the valve means blocks the path of water flow through the outer chamber by a seat-seal arrangement to direct the water into and through the inner chamber. In the continuous spray position, the valve means blocks the flow of water through the inner chamber by a bore seal arrangement to direct the water path through the peripheral chamber.

Abstract: A pipe nipple for the discharge of a solid water jet, particularly from the center of the shower head of a shower bath, is provided with an external screw thread on its water entry end and with two insets of which one is fitted tightly into each of the pipe nipple ends. Each inset has a number of openings for the passage therethrough of the water and a central bore for the reception of one of the axle pins of a spinner rotatably mounted between the two insets. The spinner has one or more obliquely pitched blades of a radial cross section at least equal to the cross section of the water openings in the entry end inset.

Abstract: A pulsating shower head comprises a liquid chamber containing a spray block having an annular channel in which are disposed movable members in the form of rotatable balls and slidable segments driven by the force of the liquid to successively cover and uncover outlet openings formed in the annular channel to produce a pulsating effect on the liquid jets exiting from the spray block. The described shower head further includes additional outlet openings for producing non-pulsating liquid jets, and a manipulatable member for selectively connecting either the annular channel outlet openings to the liquid chamber in order to produce the pulsating liquid jets or to connect the additional outlet openings to the liquid chamber to produce non-pulsating liquid jets.BACKGROUND OF THE INVENTIONThe present invention relates to shower heads, and particularly to a pulsating type of shower head wherein a pulsating effect is produced on the liquid jets exiting from the head.A number of pulsating shower heads are known.

Abstract: An oscillating spray head attachable to a source of fluid. The head comprises a housing having an inlet and outlet. A cover having apertures is secured to the outlet. An oscillating plate, provided with hollow posts extending therethrough and into the apertures in the cover, is positioned in the housing between the cover and the inlet. The plate oscillates on two bars formed on the inner face of the cover, and spaced from one another.

Abstract: A shower head is provided which can, alternatively, provide a fine, steady stream of shower water or a coarser, pulsating stream of shower water to produce a massaging effect. All of the water stream is, initially, pulsed, but the pulsation is removed when a steady stream is desired.The incoming water enters the spinner of a Hero's engine axially; it causes rotation of the engine spinner as it leaves the tangentially directed exit spouts of the engine. The water then enters a chamber having a circular outlet cover plate carrying small peripheral holes and larger, more centrally located holes inside the periphery.A rotatable dial plate is positioned between the circular outer cover plate and the plenum chamber. This plate has holes in it which can be aligned with the large inner massaging holes, with channels leading to the outer peripheral holes, or at a position in between. The position of the dial plate is controlled by an associated control arm.
