Abstract:
A paint spray gun coating liquid connector is disclosed comprising a first connector portion on one of a paint spray gun nozzle assembly or an external paint source. The first connector portion comprises a catch member. A second connector portion on the other of the paint spray gun nozzle assembly or the external paint source is adapted to establish a sealed liquid connection upon installation to the first connector portion. The second connector portion comprises a locking member that is movable to an assembly position and a locked position. In the assembly position, first connector portion can be installed onto and removed from the second connector portion, and, when in the locked position, the locking member engages the catch member such that the first connector portion is securely retained in sealing relation against the second connector portion.
Abstract:
A system includes a production process information system configured to be installed within a service shop, an air supply flow meter configured to detect air flow to a first manual sprayer and send the detected air flow to the production process information system, and a coating material flow meter configured to detect fluid flow to the first manual sprayer and send the detected fluid flow to the production process information system. The production process information system is configured to determine sprayer usage parameters based on the air flow and the fluid flow.
Abstract:
An aroma substance delivery device adapted to deliver an aroma substance exclusively to the nasal cavities of an individual, comprising the following elements: (i) a source of carrier gas flow; (ii) regulating means which receives the carrier gas flow and regulates its passage through a plurality of channels; (iii) downstream of the regulating means a plurality of aroma substance-containing cartridges, one being associated with each channel, and (iv) disseminating means located in close proximity to the cartridges and adapted to deliver the individual aroma substances from the cartridges to nasal cavities by means of a conduit; there being positioned in each channel on the upstream side and in close proximity to the origin of the channel a flow restrictor, the flow restrictor being configured such that the pressure drop across the flow restrictor is higher than the pressure drop across the rest of the device. The device is particularly useful as an element in conjunction with an audiovisual display, to provide a complete sensory experience.
Abstract:
An apparatus for ejection of a fluidized, abrasive material (4) through an adjutage (1) connected to a pressure fluid conduit (11), wherein the adjutage (1) is provided with a first ejector (14) arranged downstream of a pressure fluid nozzle (12), and a branch (142) on the first ejector (14) is arranged to be in fluid communication with a fluid source (5) through a supply line (2), and a second ejector (32) is arranged on the supply line (2), said second ejector being arranged to be submerged in a mass of particle shaped, abrasive material (4). A method for providing an outflow of a fluidized, abrasive material (4) through an adjutage (1) connected to a pressure fluid conduit (11), is also described.
Abstract:
A process for depositing nanoparticles on a surface. The process includes the steps of: providing a sol including a volatile non-aqueous liquid and nanoparticles suspended in the non-aqueous liquid; processing the sol to form a plurality of droplets; depositing the plurality of droplets on a surface; and evaporating the non-aqueous liquid from the surface leaving a residue of nanoparticles. The liquid can be selected from heptane, chloroform toluene, and hexane and mixtures thereof and the nanoparticles are desirably silver nanoparticles. The plurality of droplets may be formed by a spray process. The surface may be selected from a particular area, region, portion, or dimension of a medical device, device material, packaging material or combinations thereof. The residue of nanoparticles desirably provides antimicrobial properties.
Abstract:
A pneumatic motor that includes a cylinder (42), a piston (48) disposed in the cylinder, and a pneumatically-reset pilot valve (38). In certain embodiments, the pneumatically-reset pilot valve (38) is configured to move to a first position in response to a change in pressure in the cylinder.
Abstract:
Spray gun wherein the needle (12) for controlling the flow through the spray nozzle (13) of the gun is removable, for its periodic replacement, through the head (3) of the body (1) of the gun without requiring disassembly of other parts in addition to the spray nozzle (13).
Abstract:
The invention relates to a spray gun apparatus (10) for spraying a fine film coating of liquid, such as paint, lacquer or bond, onto a surface. The spray gun comprises a main body (12) having a fluid throughbore (22), a gas throughbore (16), and a main trigger lever (80) for allowing a user to spray fluid from the gun. A fluid flow adjustment mechanism (52, 58, 74) facilitates adjustment of the quantity of fluid sprayed from the gun for a given displacement of the main trigger lever (80). An engagement surface (86) is provided on the trigger lever and adapted to engage with a corresponding engagement surface (90) of the fluid flow adjustment mechanism. Pivoting movement of the main trigger lever (80) results in translational movement of at least a portion of the fluid flow adjustment mechanism to thereby selectively spray fluid from the gun upon displacement of the main trigger lever.
