摘要:
A process and an arrangement for hair care or therapeutic skin treatment are provided which most finely impregnate the heated and running water with CO.sub.2 directly before it is contacted with the hair or skin and which serve for lowering the pH value to values markedly below 7 due to the carbonic acid forming proportionately.
摘要:
A vessel (1) for impregnating water with carbon dioxide is pressure-tight and has inlets (4, 5) for water and carbon dioxide. Within the vessel, a cooling surface (9) is provided, connected to an external refrigeration circuit. Within the vessel and below the level of water, an underwater pump (15) is provided for producing a circulation of water inside the vessel. Carbon dioxide in finely divided form is introduced into the flowing water, preferably via the pump (15) for producing the water circulation. In use, an ice jacket (11 ) forms on the cooling surface (9).

The invention provides an apparatus for improving the water quality for hair and body care, wherein an exact impregnation ratio between CO2 and water may be maintained even at low water pressure by using a step piston 11, namely by using CO2 compressed gas cartridges which are refillable with CO2 compressed gas, and by eliminating cartridges into which water or moisture has penetrated.

By specific setting of the CO.sub.2 content and pH value of the spraying mixtures containing, apart from water, minerals and/or products for pest and disease control of the plant, the metabolism of plants is specifically stimulated and encouraged so that storage in the plants of surplus nutrients is avoided and their health and resistance is improved. The spraying mixture is constantly and over an extended period kept circulating. Both pH value and CO.sub.2 content of the spraying mixure is constantly measured. While doing this, the Ph value of the spraying mixture is exactly set. In this way the existing agricultural spraying devices having a spraying mixture circulating system are economically operated.

A device for and method of metered dispensing of liquids. The device compes a dispensing container, a sealed compensating vessel positioned within the dispensing container and engaged therewith about the opening of the dispensing container and a dosing structure positioned in the opening of the dispensing container and extending into the dispensing container and compensating vessel, said dosing structure and dispensing container having portions cooperable to form a continuous reinforcing bridge between two opposed flexible wall portions of the container. The method includes first creating a vacuum in the dispensing container prior to breaking the seal of the compensating vessel with a portion of the dosing structure by spreading the flexible wall portions of the container with the reinforcing bridge.
摘要:
An apparatus for impregnating water with carbon dioxide provides a stepped-flow channel with radial shoulders lying in planes perpendicular to the axis of the flow channel creating a zone of increased flow velocity downstream of each shoulder. Radial bores open into each stepped section adjacent the respective shoulder and communicate with a chamber surrounding the flow channel to supply the carbon dioxide to the liquid which is permitted to fill the flow channel and flow freely into an inlet section.
摘要:
A container for metered dispensing of liquid. The container in an inverted orientation is connected at its withdrawal and venting aperture to an electromagnetically actuated metering valve, wherein the metering valve has a movable valve element. Within the inverted container there is a cup-shaped vessel having a tear-off cover which simultaneously forms the closure of the container and has its rim sealingly connected to the rim of the withdrawal and venting aperture.

A method and an apparatus are proposed in order to eliminate the influencef viscosity variations in the syrup on the accuracy of metering in vending machines for the production and dispensing of still mixed drinks by considerably raising the injection pressure for the water, to eliminate the effect of the susceptibility of these syrups to spoilage by intentional aeration of the injection zone in the case of mixed drinks based on citrus syrups, and at the same time to keep the pulp particles of the citrus syrup in a desired state of suspension in the prepared mixed drink by intentional introduction of a predetermined quantity of air during the dispensing process, while avoiding foaming and clouding of the mixed drink by intentionally cutting off the introduction of air in the case of mixed drinks based on clear syrups, without the raised injection pressure having to be omitted even with these syrups.
