Abstract:
The invention relates to dispensers for cosmetic or pharmaceutical liquids (60) having a liquid reservoir (20), in which the liquid (60) is stored before a dispensing process and which is surrounded by an outer wall (30), comprising a dispensing opening (44) for dispensing the liquid (60) into a surrounding atmosphere and an uptake tube (40) that extends from the dispensing opening (44) into the liquid reservoir (20). According to the invention, the outer wall (30) of the liquid reservoir (20) and the uptake tube (40) are designed as a common integral component. The invention further relates to the use of said dispenser as a cost-effective dispenser, in particular for dispensing only one batch of liquid.
Abstract:
The invention relates to a method for cleaning surfaces of a finned heat exchanger, wherein compressed air and water are used for cleaning and the compressed air is supplied to a jet nozzle (1), which has a section (7) converging to a constriction (6) and a subsequent diverging section (8), and the water or another liquid substance is fed into the flow of compressed air preferably upstream of the jet nozzle (1), or in a different embodiment upstream of, in or downstream of the constriction (6) in the jet nozzle, wherein the jet nozzle (1) is directed at the cavity in a finned heat exchanger formed by the fins, wherein the jet penetrates the cavity between adjacent fins for the purpose of cleaning the fin surfaces.
Abstract:
Procedure and device for the micro-mixing of miscible or immiscible fluids through reflux cell, produced by the invasion of one of the fluids going upstream into the feeding tube of the other fluid. This tube is closed and has a tube exit which is placed opposite an area of confluence where the exiting flow of the intercepted fluid meets an approximately perpendicular current of invading fluid, which is radially and centripetally directed to the axis of this exiting flow. The product is released outside through an exit orifice. The edges of the tube exit and the exit orifice are opposite each other and separated by an axial gap; and the penetration of this reflux cell into the feeding tube is regulated by controlling the velocity of the fluid. An application of the invention is the ironing with a steam-aided water spray of drops smaller than 200 microns.
Abstract:
An exemplary sprinkler system includes a liquid supply conduit and a gas supply conduit. A mixing device is coupled to the liquid supply conduit and the gas supply conduit. The mixing device is configured to establish a mixture of liquid from the liquid supply conduit and gas from the gas supply conduit. The mixture has a selected gas-to-liquid ratio. A sprinkler supply conduit is coupled with the mixing device for carrying the mixture downstream from the mixing device. A sprinkler coupled with the sprinkler supply conduit is configured to receive the mixture and to discharge a fire suppression mist.
Abstract:
The invention relates to a method and apparatus for operating a plant for resinating material as part of the manufacture of materials boards, where the plant is designed for a given maximum possible throughput of fibres/chips per unit time for resination, and before the contacting of the binder (5) with the fibres (2) or chips (24), the binder (5) can be mixed with steam (6) to give a steam/binder mixture (15), and the binder (5) or the steam/binder mixture (15) is let down into a transport pipe (1) or into a mixing means (22) via an opening (23), more particularly an adjustable opening (23), of at least one nozzle (3), and is brought into contact with the fibres (2) and/or the chips (24). The invention for the method comprises the binder (5) being contacted in the form of a steam/binder mixture (15) with the fibres (2) and/or chips (24) up to a throughput of up to 66% of the maximum possible throughput, preferably up to 50% of the maximum throughput. Characteristic features of the apparatus of the invention are that the steam line (17) and the binder line (16) connect with at least one mixing chamber (7), and the steam line (17) includes a steam valve (30) disposed substantially adjacent to or bordering on the mixing chamber (7). (1419).
Abstract:
Apparatus and methods for generating and dispensing a mixture containing a pressurized gas and a fluid material. The apparatus includes a mixing device (16) having a mixing chamber (30) and a mixer inside the mixing chamber. A gas injection device (60), which is coupled with the mixing device (16), injects the pressurized gas into the fluid material in the mixing chamber (30). The mixer operates to combine the pressurized gas with the fluid material to form a mixture, which is subsequently dispensed from a dispenser coupled with the mixing device (16).
Abstract:
The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.
Abstract:
A liquid adhesive dispensing system operable for more uniformly applying liquid adhesive foam onto moving substrates, notwithstanding changes in line speed, adhesive liquid flow rates, or foaming/atomizing air pressures. The illustrated liquid adhesive system includes a header having a plurality of air atomizing spray guns; the spray guns each having a respective variable speed positive displacement pump for directing a metered quantity of liquid adhesive from a liquid adhesive supply to the respective spray gun; and a control for controlling the operating speed of the positive displacement pumps in relation to the speed of the moving substrate and the foaming/atomizing air pressure to the spray guns in relation to the operating speed of the positive displacement pumps. The control further is operable for monitoring pressures across the positive displacement pumps for insuring the accurate direction of metered quantities of liquid to the spray guns. The spray guns are adapted for enhanced liquid adhesive foaming and atomization, and the header is convertible into a closed housing structure effective for containing cleaning and purge liquids during an automatically operable cleaning cycle of operation.
