Abstract:
The disclosure concerns a mixing valve for mixing two coating agent components (e.g. master batch and hardener) to form a multi-component mixture, with two coating agent inlets for supplying the two coating agent components and with two coating agent valves for controlling the coating agent flow through the two coating agent inlets, as well as with a coating agent outlet for discharging the multi-component mixture in a specific outflow direction. The disclosure provides that at least one of the coating agent valves is formed as a rotary slide valve having two plane-parallel valve discs which are rotatable relative to each other about an axis of rotation.
Abstract:
A fluid flow nozzle is provided that comprises an elongated body having an inlet end and an outlet end, and defining a channel extending therethrough in which the channel includes an inlet channel and an outlet channel having an outlet diameter that is less than the inlet diameter. The channel further defining a tapered channel extending from the inlet channel to the outlet channel with a plurality of vanes or grooves circumferentially spaced around the tapered channel to increase flow velocity while reducing turbulence and divergence of the discharge stream.
Abstract:
A new firefighting nozzle has a series of moveable vanes that extend inwardly from a peripheral wall of a base. The inner side of the vanes extends between ⅛ and ⅜ of the diameter of the central channel. The vanes rotate between a linear position, in which the vanes are generally parallel to the direction of the channel, and a vortex position, in which the vanes are significantly angled with respect to the direction of the channel. In the linear position, smooth bore linear flow is produced. In the vortex position, any of a range of fog patterns are produced. An externally mounted controller connects to the vanes and enables a firefighter to change the shape of the nozzle's spray without interrupting the flow. The controller and base have a series of pins that slide in a spiral groove and cause the shaper to move axially with respect to the base when the shaper is rotated about the base. Radial stems that ride in a circumferential slot translate that axial movement into rotation of the vanes.
Abstract:
A spray cap (20; 300; 400; 600) for a spray can (22) has a body comprising: a sidewall (140) having a lower portion for mounting to a body of the spray can; and a button (36). The button has: an upper surface (164) for user engagement; a downwardly projecting sleeve (38) for receiving an outlet stem (240) of the can; and a forwardly-open compartment (42). An insert (34; 302) is within the compartment. A nozzle member (32) is mounted across the compartment to contain the insert within the compartment.
Abstract:
A distributor tray for a gas and a liquid circulating as a co-current, said tray comprising a plate perforated by orifices and supporting hollow chimneys extending perpendicularly to said plate, each orifice of the plate being surmounted by a chimney of identical cross section to said orifice, characterized in that the plate is equipped with a plurality of openings arranged on the periphery of each chimney inside a circumscribed circle, the center of which coincides with the center of the chimney, and the radius of which is less than or equal to ⅓ of the shortest distance separating two adjacent chimneys, and in that a single deflector element is arranged beneath each chimney, the openings and the deflector element associated with each of the chimneys being so arranged as to impart a rotating movement to the gas/liquid mixture under each chimney.
Abstract:
The present disclosure relates to a pull/push type closure or cap assembly, which is compatible with a number of plastic bottles for providing two different types of fluid flow therethrough.
Abstract:
A fuel nozzle having a flow pathway including a smooth, sharp, or mitered bend prior to a nozzle tip is provided. The fuel nozzle injects fuel into a combustion chamber with an even flow distribution of the fuel and substantially reduces undesirable acoustic resonance encountered in a fuel nozzle body in a combustion system.
Abstract:
A topical spray composition and a system for containing and applying the composition is described. The composition has liquid emulsifiers that unexpectedly result in a superior product suitable to be applied homogeneously.
Abstract:
A shower head (10C) has at least one mixing chamber (24) having an air inlet (18) for connection to a supply of pressurised air and a water inlet (22) for connection to a supply of pressurised water so that, in use, the air breaks the water up into droplets in the mixing chamber. The mixing chamber further has at least one outlet (32) so that, in use, the water droplets and air exit the shower head to form a shower of water droplets having a mean trajectory. The or each outlet is arranged so that, in use, at least a substantial proportion of the water droplets exit the shower head so that their individual trajectories on leaving the shower head are offset from the mean trajectory of the shower head and converge towards the mean trajectory of the shower head. This can result in a more uniform distribution of water droplets in the shower pattern. A single annular outlet may be provided, or a plurality of separate outlets. In order to assist in breaking up the water into small droplets, a vortex may be induced in the air and/or the water in the mixing chamber, and/or a deflector may be disposed adjacent the water inlet into the mixing chamber.
