A jet regulator (1) for a sanitary faucet (2) that contains a first spray plate (3) for dispensing the liquid as a laminar jet; and a second spray plate (4) for dispensing the liquid as a mist jet. Moreover, a sanitary faucet (2) having such a jet regulator (1) is proposed.

Systems and methods are provided in which residual materials are removed from an interior surface of a drum or similar vessel at the end of a duty cycle. This is followed by application of a non-siliceous aqueous solution to the cleaned surface, which provides a durable low-friction coating to the interior wall of the rotating drum mixer throughout the following duty cycle or use.

A spray cap system is described that can enable a user to more consistently and accurately dispense and work with the contents of a spray can. The system includes a spray cap, spray button, spray nozzle, implement holder, and an implement (such as a brush, a foam pad applicator, or a sponge). By using the spray cap system, a user may achieve a more optimal discharge pattern of the contents of the can with a more efficient and optimal coverage of a surface. In addition, the user may utilize the implement while it is attached to the spray cap or remove the implement to use the implement independently. The spray cap system provides versatility to a user by enabling the user to spray the contents of the spray can regardless of whether the implement is attached to the spray cap.

A process for coating a carrier material with an active material for production of an electrode foil of a battery cell with a Laval nozzle, wherein the Laval nozzle has at least one converging first portion, one second portion having a smallest flow cross section, and one diverging third portion arranged one after the other along a flow direction.

A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

Nozzle designs which have been found to be effective in governing overspray in OVJP are provided. Aspects of the invention have been found to be effective in reducing or avoiding sudden pressure drops at the end of the nozzle close to the substrate, and may be advantageously employed in obtaining, for example, greater consistency between the nozzle outlet diameter and the deposited pattern width.

An apparatus for cavitation peening is disclosed, including a fluid source, a conduit, and a portable nozzle assembly. The conduit includes a proximal end portion connected to the fluid source and a distal end portion connected to the portable nozzle assembly. The portable nozzle assembly includes an inner nozzle configured to channel a first stream of high-pressure fluid, and an outer nozzle configured to channel a second stream of low-pressure fluid concentrically around the first stream. The inner nozzle includes a cavitation insert having an inner passage with at least two reductions in cross-sectional area.

An adjustable nozzle having a nozzle body having an inlet section with an inlet opening, an outlet section with an outlet opening, and a fluid flow path extending from the inlet opening to the outlet opening; a spray restrictor segment located in the outlet section; and an actuator that displaces the spray restrictor segment toward and away from a center of the fluid flow path, thereby varying a pattern of fluid flowing from the fluid flow path through the outlet opening.

A nozzle and a process suitable for dispensing liquid foamable products, particularly useful with carbon dioxide blowing agents, the nozzle comprising a tubular exit zone having an inlet and an outlet; the tubular exit zone having an inner wall surface defining a passageway for dispensing having a centerline axis; the tubular exit zone further having a plurality of vanes attached to the inner wall surface parallel to the centerline axis with the vanes extending radially into the passageway for dispensing; the vanes having a length dimension that is the distance the vane contacts the inner wall surface parallel to the centerline axis, a thickness dimension that is the effective thickness of the vane at the inner wall surface perpendicular to the centerline axis, and a width dimension being the distance from the inner wall surface that the vane extends into the passageway for dispensing; and wherein the vanes do not connect or touch at the centerline of the passageway for dispensing.

The invention discloses a method and modified aerodynamic apparatuses: fluid pushers-off and fluid motion-sensors, making enable efficient implementation and use of a controllable enhanced jet-effect, either the waving jet-effect, the Coanda jet-effect, the lift-effect, the effect of thrust, the Venturi effect, and/or the de Laval jet-effect, all are controllable using the Peltier effect and/or the Seebeck effect. The modified aerodynamic apparatuses are geometrically shaped and supplied with built-in thermoelectric devices, wherein the presence of the thermoelectric devices provides for new functional properties of the modified aerodynamic apparatuses. The method solves the problem of effective control of the operation of modified aerodynamic apparatuses such as airfoil wings of a flying vehicle, convergent-divergent nozzles, loudspeakers, and detectors of acoustic waves, all of a highly-efficient functionality.
