Abstract:
In one aspect, a sprinkler is provided having a nozzle, a deflector that receives fluid flow from the nozzle, and a friction or viscous brake assembly that controls rotation of a deflector. The friction or viscous brake assembly is releasably connected to the frame in order to enhance serviceability of the sprinkler. In another aspect, a sprinkler is provided having a frame, a deflector rotatably connected to the frame, a nozzle, and a nozzle socket of the frame. The nozzle and nozzle socket have interlocking portions that releasably connect the nozzle to the frame. The nozzle may be easily removed for servicing. Further, the nozzle socket can be configured to receive a plurality of nozzles having different flow characteristics. A nozzle can be selected and utilized with the sprinkler according to the desired application for the sprinkler.
Abstract:
An annular gap space (18), into which a part of turbine air for driving a turbine (6) and exhaust air discharged from a rear thrust air bearing (12) flow out, is provided between an inner peripheral surface (5B) of a rotational shaft (5) and an outer peripheral surface (17B) of a feed tube (17). Air outflow holes (25) are provided in the rotational shaft (5) to be positioned between a radial air bearing (8) and a rotary atomizing head (16) and to be radially bored through the rotational shaft (5). As a result, the exhaust air flowing in the annular gap space (18) flows out outside of the rotational shaft (5) from the air outflow holes (25) in a position behind the rotary atomizing head (16).
Abstract:
Disclosed is a system for distribution of granular salt or brine from a vehicle. The system includes an auger assembly of a pair of powered independently rotating flighted auger sections disposed in an auger box and receiving salt stored by the vehicle. Each auger assembly has a discharge end surrounded by a choke fitting closely thereto and located at opposite ends. The system also includes a pair of powered spinner assemblies. Each spinner assembly is located beneath an auger discharge end for receiving salt from each auger assembly. Each spinner throws salt operates independently and rotates in an opposite direction. When salt is to be thrown from only one of the spinner assemblies, both of said auger assemblies rotate in the same direction for feeding the spinner assembly that is throwing salt. Nozzles directed onto each operating spinner assembly sprays brine thereonto.
Abstract:
A manually operable spreader which can be moved from behind on a surface is especially suitable for distributing salt and other particulate materials which tend to conglomerate or clump in a hopper of the spreader. Wheels are mounted to a frame also support the hopper. A horizontal drive shaft between the wheels is coupled to rotate a vertical shaft. A distributor below the hopper rotates with vertical shaft rotation to distribute particulate material which drop via openings in the bottom of the hopper. The vertical shaft extends via a hole in bottom of hopper and carries at the top thereof an auger having a helical vane. The auger is rotatable with the vertical shaft as the spreader is moved on its wheels. The auger circulates the particulate material in the hopper as the spreader moves while directing material in the hopper towards the bottom thereof.
Abstract:
A device for spreading a granular material over a road surface. The device includes a hopper fillable with the granular material and an agitating member configured to discharge the granular material from an outlet of the hopper. A brush is aligned with the outlet of the hopper and includes a plurality of bristles configured to inhibit leakage of the granular material from the outlet of the hopper during stoppage of the agitating member. Also provided are a system in which the spreader device is mounted on a vehicle, and a method of operating the spreader device.
Abstract:
An apparatus for applying mortar is provided. The apparatus includes a support sled and a mixer positioned on the support sled. The mixer combines a received dry powder mortar and a liquid, and a pump positioned on the support sled and adapted to pump the mixed mortar and liquid. The apparatus further includes a spray head positioned on the support sled and adapted to receive the pumped mortar and liquid mixture and spray the mixture.
Abstract:
A method and system for the atomized dispersion of a liquid composition using one or more electrically or hydraulically driven fans with atomizers. In one example, air flow from a plurality of fans, each in proximity to an atomizer driven by an overdrive unit at 2-10 times the fan speed, provides an efficient dispersion 30-50 micron droplets of a scavenger in order to effectively suppress hydrogen sulfide in an area such as an oil well. The system provides a rapid response when H2S exceeds a threshold concentration. The fans deliver atomized scavenger over a relatively large area, so that the scavenger can tie-up or neutralize large amounts of H2S very quickly.
Abstract:
An applicator for applying a product includes a motor and a switch for automatically rotating and/or oscillating an applicator head. By virtue of having a motor with a throttling gear, the applicator is capable of rotating and/or oscillating at controlled frequencies during application of cosmetic, medicinal, or other products to a surface.
Abstract:
The invention relates to a droplet break up device (1) comprising: a chamber (2) for containing a pressurized printing liquid (3) comprising a bottom plate; at least one outlet channel (4, 4′) having a central axis, provided in said chamber for ejecting the printing liquid; and an actuator for breaking up, a fluid jetted out of the outlet channel. The actuator comprises a revolving, member (5) comprising a surface deformation (7, 7′) shaped to provide a pressure pulse near the outlet channel. Accordingly, a simple mechanism is provided for providing multiple printing nozzles.
Abstract:
A method and apparatus for applying coatings to a portion of the internal bore or threads of a fastener or similar article having an opening on at least one end is provided. A 360null coating with material is provided using centrifugal force to assist in direction the material to a desired surface, which does not require use of a pressurized air stream in order to propell the coating material toward the walls of the article desired to be coated.
