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 mist generating apparatus is provided. The apparatus has a longitudinal axis and comprises first and second opposing surfaces which define a transport fluid nozzle between them. The apparatus also has a working fluid passage having a supply passage connectable to a supply of working fluid, and an outlet on one of the first and second surfaces. The working fluid outlet communicates with the transport fluid nozzle. The transport fluid nozzle has a nozzle inlet connectable to a supply of transport fluid, a nozzle outlet, and a throat portion intermediate the nozzle inlet and nozzle outlet. The nozzle throat has a cross sectional area which is less than that of either the nozzle inletor the nozzle outlet. The transport fluid nozzle projects radially from the longitudinal axis such that the nozzle defines a rotational angle of at least 5 degrees about the longitudinal axis.

A smoke generator for anti-burglar purposes comprising canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further comprises a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.

A blowing nozzle having a substantially parabolic blowing end is provided which entrains ambient gasses into the output flow. A plurality of outlets are arranged so as reduce turbulence within the flow. The substantially parabolic blowing end converges at an apex coaxial with a blowing axis. A central outlet is provided at the apex to generate a core stream of gas. First outlets surround the central outlet. Second outlets surround the first outlets and are angled inward toward the blowing axis. Fins and/or additional outlets may be provided.

A motion guide apparatus cooling nozzle is provided which can gas-cool a motion guide apparatus. Cooling nozzles 1a and 1b of the present invention are mounted on a block 4 of the motion guide apparatus to cool at least one of a guide rail 2 and a block 4 that is assembled to the guide rail 2 via a rolling element 6 in such a manner as to be movable relatively. The cooling nozzles 1a and 1b include an inner passage 18 into which gas is introduced, an opening 12a configured to emit a gas flow introduced into the inner passage 18, a deflection surface 22a that is provided adjacently to the opening 12a to bend the gas flow emitted from the opening 12a, and a guiding surface 32a configured to attract gas outside the cooling nozzles 1a and 1b.

A fire protection nozzle includes a body having inlet and outlet orifices defining a body axis, and a flow passage for a fluid that flows through the body in an output direction, frame arms having proximal ends connected to the outlet orifice and distal ends, the frame arms defining a frame arm plane, a junction formed by the frame arms distal ends at a distance from the outlet orifice, the junction including a central bore and an outer wall, and body deflectors extending from each of the frame arms in the frame arm plane at an angle relative to the body axis. Each of the body deflectors has an inner planar surface facing the junction. The nozzle also includes a planar member deflector to be mounted to the nozzle body. The deflector includes a planar member having a plurality of slots on a periphery that define a plurality of tines.

A nozzle including an elongate body and a nozzle outlet subassembly. The elongate body includes a first passageway. The nozzle outlet subassembly is disposed at least partially within the first passageway. The nozzle outlet subassembly includes a nozzle terminal and a diffuser. The nozzle terminal defines a second passageway and a spray opening. The diffuser defines a diffusion opening that is proximate the spray opening.

A hand dryer includes a nozzle for blowing out an airflow toward a drying space, which is open at the front and the left and right sides so that hands can be freely inserted and withdrawn, and a wind direction changing part that changes a direction of the airflow blown out vertically downward from the nozzle. The wind direction changing part is so positioned as to be shifted rearward in a front-back direction from a position on an extension of a blow direction of the nozzle. While the airflow is being blown out vertically downward from the nozzle, the wind direction changing part and the nozzle do not directly face each other.

An ultrasonic atomization material applicator includes a material applicator with at least one transducer and an array plate with an array of micro-applicators. Each of the micro-applicators has a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. At least one supply line is in communication with the micro-applicators and configured to supply at least one material to each of the micro-applicators. The at least one ultrasonic transducer is mechanically coupled to the at least one array of micro-applicators and configured to vibrate the at least one array of micro-applicators such that atomized droplets of the at least one material are ejected from each of the micro-applicators. A movement device configured to cyclically move the at least one array of micro-applicators back and forth about at least one axis of the at least one array of micro-applicators can be included.
