A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.

A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.

A thin film induction nebulizer is disclosed herein. The nebulizer has a gas capillary and a liquid capillary that are aligned in the same direction within a nebulizer housing and are substantially aligned with a main axis of the nebulizer housing. The nebulizer includes a liquid opening configured to allow liquid to exit the liquid capillary and a gas orifice configured to allow gas to exit the gas capillary. The liquid capillary opens into a chamber that is formed from a liquid channel having a roughened surface and a cover plate. The cover plate interfaces with the liquid channel to partially seal the chamber. The chamber includes an opening where the liquid opening opens into the chamber and also includes another opening proximal to the gas orifice. The end of the nebulizer housing that is proximal to the liquid opening and the gas orifice includes two angled exterior surfaces.

The present disclosure may provide a cleaning apparatus for cleaning parts. The cleaning apparatus may comprise a housing defining a washing chamber having an opening through which parts may be loaded/unloaded into the washing chamber. The cleaning apparatus may also comprise a spray system adapted to direct a washing solution to clean the part in the washing chamber. The spray system may comprise a spray array with at least one rotatable spray head. The spray head may comprise a plurality of nozzles through which the washing solution is directed to clean the part in the washing chamber. The cleaning apparatus may also comprise a closure which may provide controlled access to the washing chamber through the opening and may be movable between a closed position to sealingly close the opening and an open position so as to allow for loading and unloading of parts into the washing chamber without obstruction.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

A fire protection sprinkler includes a sprinkler frame and a deflector. The deflector is coupled to the sprinkler frame and distributes fluid discharged from an outlet of the sprinkler in a spray pattern centered about a sprinkler axis and defined by a fluid density in a first quadrant area 2.5 feet (ft.) below the sprinkler and perpendicular to the sprinkler axis, the first quadrant area having a first corner disposed along the sprinkler axis with a first edge extending in the direction of a fluid supply pipe, a second edge extending perpendicular to the first edge and intersecting the first edge at the sprinkler axis, the first quadrant area being defined by a grid of one square foot areas totaling an area of no more than 10 ft.×10 ft., the total fluid density being at least 15 gpm/sq. ft.

A nebuliser for nebulising liquid droplets, including: a housing; at least one piezoelectric substrate (2) accommodated within the housing and having a transducer surface (2a) upon which is located at least one electroacoustic transducer (48) for generating acoustic wave energy within the at least one piezoelectric substrate (2), and an opposing non-transducer surface (2b); a liquid supply system for supplying a liquid to at least one of the transducer and non-transducer surfaces, the liquid supply system including a reservoir (3) for accommodating the liquid, and at least one relatively rigid supply conduit in contact with the at least one piezoelectric substrate (2) for supplying the liquid from the reservoir (3) to the at least one piezoelectric substrate (2); and a sensor for detecting a volume of liquid on the at least one piezoelectric substrate (2).

A rotary sprinkler comprises a rotatable irrigation head with one or more nozzles, associated with liquid feed lines, which extend thereto from a sprinkler base housing, and further comprises a static biasing control base located below the irrigation head, e.g. between the sprinkler base housing and the irrigation head. The sprinkler can comprise a flow regulator arm, whose movement, at least indirectly, results in reducing the cross-sectional area of liquid flow towards at least one of the nozzles, and a flow deflector arm configured to interfere with a liquid jet discharged from at least one of the nozzles in order to affect the angle and range of the liquid jet. The static biasing control base can comprise an array of biasing elements, which can bias a cam follower configured to rotate together with the irrigation head and transfer its rotational displacement to the flow regulator arm and flow deflector arm, e.g. through respective gear elements. The gear elements can be adjusted to control a ratio between the extent of deflection of the two arms due to the rotation of the cam follower. The rotatable irrigation head can comprise a cover for preventing exposure of the dynamic control elements to the exterior of the sprinkler.

A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.

A concealable sprinkler head includes a frame having a body mountable to a fire suppression liquid source, a pair of frame arms and a pair of corresponding drop pins slidably engaged with a respective frame arm. A thermal trigger is supported within the sprinkler frame. A fluid deflector is secured to the drop pins and includes a generally horizontal surface. The drop pins extend substantially orthogonally from the horizontal surface. An inclined surface of the fluid deflector extends angularly upwardly from the horizontal surface. A concealing cup surrounds the frame arms. A cover plate is attached to the concealing cup, covering the distal end thereof, wherein the drop pins and the deflector are positioned within the concealing cup. The cover plate is removable from the concealing cup permitting the drop pins and the deflector to axially slide out of the concealing cup into an operational position.
