  • Patent number: 9772133
    Abstract: An ice making device and a method of making ice. A plurality of passages for refrigerant, preferably, multi-component refrigerant, is in thermal communication with a freezing surface, for example in an outer shell surrounding a body. The passages each include an inlet and an outlet. The inlet for a passage may be disposed approximately 180° from the outlet for that passage. The outlet for the passages may form the inlet for the subsequent passage. The size of the outlets may be smaller than a cross-sectional size of the passage. As the refrigerant moves through the passages, water on the freezing surfaces will freeze and form ice. A blade will scrape the ice off.

  • Patent number: 9409639
    Abstract: A method and system for creating a water wall around the perimeter of a ship by pumping a high-pressure water stream through a plurality of rotational water dispensing heads positioned around the perimeter of the ship. Each of the water dispensing heads produces a water circle and the overlapping water circles create a water wall around the ship that cannot be broken by the intruders attempting to approach the ship and to climb on board. Each water heads has several jets dispensing water streams under high pressure. The water heads rotate under an impact of the water streams coming at an angle from the water dispensing jets. Thus, the entire boat is covered by a continuous water wall barrier, which does not allow for any intrusion attempts from another boat or from a pier.

    Abstract: A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone.

    Abstract: An ink jet is disclosed that may be placed in a bell plate of a rotary atomizer and, when thus placed, forms an annular gap between the ink jet and a distribution disc recess of the bell plate. An exemplary illustration has a common rinsing agent channel running in the ink jet for conducting a rinsing agent for rinsing the bell plate, a first rinsing agent outlet that is supplied with rinsing agent by the common rinsing agent channel and directed forward in a substantially axial direction toward a distribution disc of the bell plate, and a second rinsing agent outlet that is supplied with rinsing agent by the common rinsing agent channel. In the installed state, an exemplary second rinsing agent outlet may empty into the annular gap between the distribution disc recess and the ink jet in order to clean the annular gap with the rising agent.

  • Patent number: 8079532
    Abstract: An energy efficient water sprinkler has a housing with primary and secondary water chambers each with a turning wheel for translating the force of impacting water to rotational motion of a central shaft journal. Water is forced through a central channel in the rotating shaft and discharged from the housing. A portion of the discharged water is directed to deflection fins on the outer surface of the housing to further impart rotational or energy to the rotating shaft.

  • Patent number: 8074897
    Abstract: A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.

  • Patent number: 8028932
    Abstract: A rotary, nutating sprinkler head includes a housing supporting a nozzle; a starter tube axially adjacent the nozzle and extending in a downstream direction, concentric with a vertical center axis of the sprinkler head. A spool assembly is loosely supported on the starter tube, the spool assembly including a double-flanged spool and a water-deflection plate carried by the spool, the water-deflection plate formed with one or more grooves shaped to cause the spool assembly to rotate when impinged upon by a stream emitted from the nozzle. Either the starter tube or the spool is provided with at least one tilting lug located to keep the spool assembly in a tilted or angularly offset orientation relative to the vertical center axis, thereby facilitating a wobbling action of the spool assembly during rotation.

  • Patent number: 8020788
    Abstract: A showerhead providing an improved pause mode that restricts the amount of water emanating from the head. The showerhead includes a first and second outlet nozzle, a valve body operative to be in fluid communication with a shower pipe, the valve body having first and second flow channels in fluid communication with the shower pipe, each of which is also in fluid communication with one of the outlet nozzles. The first and second flow channels have different cross-sectional areas. In another embodiment, the valve body further includes a valve center in fluid communication between the first flow channel and the shower pipe, and is also in fluid communication between the second flow channel and the shower pipe. The valve body further defines a first hole in fluid communication with the first flow channel and the valve center, and a second hole in fluid communication with the second flow channel and the valve center, with the second hole having a smaller cross-sectional area than that of the first hole.

  • Patent number: 7959092
    Abstract: A coating machine enables the inside of a paint chamber to be washed clean with less amount of use of thinner by increasing washing efficiency and is capable of forming a coating with uniform coating thickness by always uniformly jetting a paint over 360° about a rotary atomizing head and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which the paint chamber is formed in the clearance between an outer bell fitted to the tip of a tubular rotating shaft and an inner bell fitted to the front side of the outer bell. Fins agitating, in the paint chamber, a washing fluid supplied from a thin tubular nozzle inserted into the tubular rotating shaft are radially formed on the rear surface side of the inner bell. An annular paint groove temporarily accumulating the paint is formed in the inner surface of the rim part of the outer bell on which the paint jetted from the paint jetting holes formed at the peripheral surface part of the paint chamber is extended.
