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:
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:
A method for calculating a shape of a painting spray head that injects liquid paint supplied to the center in a radial direction while rotating, includes: inputting a material characteristic of painting liquid to be injected; selecting a start point where a curve starts on a front surface of the painting spray head; calculating the thickness of a liquid film injected from the painting spray head through an input numerical value; correcting the start point where the curve starts depending on a difference value between the calculated thickness of the liquid film and a required thickness of the liquid film; and calculating a curve shape of the painting spray head by using the corrected start point.
Abstract:
A dampening unit that sprays viscous application liquid to a treatment surface includes a rotating brush driven to rotate around the axis, a liquid applicator that supplies the liquid to the brush, and a brush chamber to accommodate the brush. The brush chamber includes a wall that surrounds the brush. The wall defines an ejection window for discharging viscous application liquid that is either sprayed or spun away from the brush.
Abstract:
In some embodiments the present disclosure provides a sprinkler comprising: a nozzle for projecting a stream of liquid in a first direction; and a spinner having a liquid deflecting surface, which is pivotally mounted in-line with the nozzle such that a stream of liquid from the nozzle impinges on the liquid deflecting surface; where the liquid deflecting surface is shaped such that the stream of liquid causes the spinner to spin and furthermore, where the liquid deflecting surface is shaped such that the stream of liquid is deflected in a second direction that is substantially transverse to the first direction. Additional embodiments of this disclosure pertain to the sprinkler that includes a frame, where the spinner is pivotally mounted on the frame.
Abstract:
A spray head for spraying mortar is provided. The spray head includes a mortar supply pipe and a spinning head positioned at an outlet point of the mortar supply pipe, the spinning head directing mortar supplied from the mortar supply pipe in a direction substantially perpendicular to the direction of travel of mortar in the mortar supply pipe. An air intake for receiving air is further provided, the air being employed to spin the spinning head pneumatically. Finally, a material input port is provided for inputting material to be combined with the mortar in the mortar supply pipe at the outlet point of the mortar supply pipe.
Abstract:
The invention concerns a device comprising a rotary body (1) made of a fibrous or porous material, means for rotating (3, 4) said body (1) and means for inputting liquid (10, 11) contacting said body (1), so as to subject said liquid to the dispersing action of forces at the liquid/solid interface, and to rotate the body (1) so as to subject the comminuted liquid to a centrifugal force.
Abstract:
The invention provides a method for the production of composite elements composed of at least one outer layer a) and a thermal insulation material b), where between the outer layer a) and the thermal insulation material b) an adhesive c) has been applied, the outer layer a) being moved continuously, the thermal insulation material b) being applied to the outer layer a) and, if appropriate, a further outer layer a) being applied to the thermal insulation material b), and the adhesive c) being applied to the thermal insulation material b) or to the outer layer a), which comprises applying the adhesive c) by means of a rotating flat body which is mounted horizontally or with a slight deviation from the horizontal, of up to 15°, preferably parallel to the outer layer a) or to the thermal insulation material b).
Abstract:
Method and device for continuously producing a coherent layer of a liquid/melt of even thickness by means of centrifugal action along the entire periphery of a rotating disk (13, 113), liquid/melt being supplied to the disk around its entire axis of rotation from means (12, 112) and leaving the disk as individual droplets. The means (12, 112) distributing the liquid/melt onto the disk (13, 113) has according to the invention essentially the same speed and direction of rotation as the disk, and the liquid/melt undergoes under the influence of centrifugal action circumferentially a spreading and change in velocity across the disk (13, 113) in contact with the same.
