Abstract:
The invention intends to prevent the occurrence of a phenomenon that air is sucked through an ejection port formed at a nozzle end when a plunger rod is retracted to move away from a valve seat. In a method or apparatus for ejecting liquid droplets in which a liquid under regulated pressure, the liquid being stored in a container as required, is ejected while it is caused to fly in the form of liquid droplets from a valve ejection port, bubbles are prevented from being mixed into the liquid through the ejection port by controlling a supply amount of the liquid in a manner being able to follow a pressure difference between the ejection port and a flow passage in a valve body. The liquid is continuously ejected at a high-speed tact. The ejection port is opened with a plunger rod retracted by air pressure, and the liquid droplet is ejected through the ejection port with the plunger rod advanced by a resilient force of a spring. Bubbles are prevented from mixed in the liquid through the ejection port upon retraction of the plunger rod by controlling a retraction speed of the plunger rod in accordance with an air flow rate.
Abstract:
A system utilizing a rotary atomizer for applying a liquid based substance to particles. In one example, a motor provides an in-line, direct drive force on a cage atomizer. With some systems, the cage atomizer has a vertical axis of rotation. With some systems, the motor is mounted external to the particle path and supported by a housing structure that provides an angled particle path. With some systems, other types of rotary atomizers may be used such as disk, bowl, or hollow disk rotary atomizers. With some examples of cage atomizers, a first portion of the cage atomizer may include a thread set that screws to a thread set of a second portion to hold a perforated structure in place. With some systems, the thread sets surround the axis of rotation.
Abstract:
A fluid pump for pumping fluidized materials comprises a motor, a material pump, and a closed-loop pressure hydraulic system interconnecting the motor and the material pump. The closed-loop hydraulic system further comprises a hydraulic pump, a pressure regulator, an impeller, and an expandable fluid reservoir. The motor includes an output to drive the hydraulic pump, which pumps hydraulic fluid throughout the closed-loop hydraulic system. As the hydraulic fluid flows throughout the closed-loop system, it passes through the impeller, which in turn drives the material pump to deliver the fluidized material from a material reservoir to an outlet valve for dispensing the material.
Abstract:
A mist-producing umbrella device for providing a soothing and cooling mist for users on a hot day at a beach. The mist-producing umbrella device includes an umbrella assembly including an elongate tubular support member and a collapsible canopy mounted upon a top end of the elongate tubular support member; and also includes a water control assembly including a housing being removably attached to the elongate tubular support member, and also including a water reservoir being disposed in the housing, and further including a pump being disposed in the housing and being connected to the water reservoir; and further includes a mist-dispensing assembly including a conduit being connected to the housing, and also including tubular branch members being securely attached to the elongate tubular support member and extending radially therefrom.
Abstract:
Spherical particles having a size on the order of 0.1 to 100 microns in size are created by systems and devices of several types. The device includes a source of a stream of gas which is forced through a liquid held under pressure in a pressure chamber with an exit opening therein. The stream of gas surrounded by the liquid in the pressure chamber flows out of an exit orifice of the chamber into a liquid thereby creating a monodispersion of bubbles with substantially uniform diameter. The bubbles are small in size and produced with a relatively small amount of energy relative to comparable systems. Small particles of liquid may also be produced. Applications of the technology range from oxygenating sewage with monodispersions of bubbles to inhalation therapy with monodisperse aerosol dispersions of pharmaceutically active drugs.
Abstract:
An apparatus for treating particle-shaped material has a process chamber for accommodating and treating the material. A base is composed of guide plates which are placed one above the other in different planes and overlap one another and between which slots are arranged, via which process air can be directed into the process chamber with an essentially horizontal component motion. It is proposed to provide a vertical-adjustment device which interacts with the guide plates and by means of which the distance between the guide plates and thus the height of the slots can be varied.
Abstract:
A bubble generating assembly has a housing, a container coupled to the housing and retaining bubble solution, a trigger mechanism, a pair of bubble generating rings, a tubing that couples the interior of the container with the rings, and a link assembly that couples the trigger mechanism and the rings in a manner in which actuation of the trigger mechanism causes the rings to be pivoted. Each ring is pivotably coupled to each other in a manner such that the rings can be pivoted between a closed position where the front surfaces of the rings contact each other, and an opened position where the rings are positioned side-by-side in the same plane.
Abstract:
A system for flushing an airless sprayer essentially reverses operation such that the spray gun is immersed in a container of water or other solvent and that fluid is pulled through the pump and flushed through the normal inlet tube. The preferred embodiment attaches a fluid bar to the front of the spray gun to redirect the fluid for flushing. This reverse flushing action allows quicker flushing using less fluid.
Abstract:
A method for performing an aperture plate comprises providing a mandrel that is constructed of a mandrel body having a conductive surface and a plurality of nonconductive islands disposed on the conductive surface. The mandrel is placed within a solution containing a material that is to be deposited onto the mandrel. Electrical current is applied to the mandrel to form an aperture plate on the mandrel, with the apertures having an exit angle that is in the range from about 30null to about 60null.
Abstract:
A spray extension device for a spray can includes at least a pair of telescopable extension tubes fitted to and in fluid communication with the valve stem of a spray can. Advantageously, the extension tubes are fitted to a closure cap which, in turn, is fitted to the valve stem, and, thereby, in fluid communication with the interior of the can. Depressing of the closure cap causes the valve stem to issue fluid therethrough, into the tubes.
