Abstract: 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.

Abstract: 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.

Abstract: A child seat for a motor vehicle is adjustable between a lower retracted state at the normal seat height of the motor vehicle seat, and an unfolded position in which the child seat stands out from the normal seat height for occupation by a child. A frame and a supporting structure are connected and hinge-jointed to each other by front and rear parallelogram arms. At least one diagonal locking brace is hinged on one side to one of the frame, the supporting structure and one of the parallelogram arms, and on an other side is guided by a tranverse part in a longitudinal guide. A locking segment has at least one holding notch to accommodate the transverse part, with flanks extending transversely to the longitudinal guide and a handle for releasing the tranverse part from the holding notch. The handle extends over a region of a front surface of the child seat.

Abstract: An inflatable child seat includes at least two air chambers. The child seat is foldable when the at least two air chambers have been evacuated to form a suitcase like body. A releasable fastener is provided for fixing the child seat in its folded position. One half of the suitcase-like body forms an air chamber representing an inflatable cushion and the other half contains air chambers forming side parts, a backrest, a head restraint and a tray of the child seat.

Abstract: A disposable CO.sub.2 gas generator cartridge of cylindrical construction and including inner and outer coaxial reagent chambers which are interconnected when installed in a cylindrical pressure vessel and having a top cover assembly including a pusher type activating mechanism which is operated by a cam surface located on a handwheel. The cover assembly connects to a carbonated drink dispenser by means of a quick disconnect coupling activated by the operation of a manually operated pull down lever assembly including the handwheel. Operation of the handwheel acts to start gas generation and also vent the cartridge to atmosphere when spent.

Abstract: A method of qualitatively and quantitatively improving the fertilization of plants comprising impregnating a plant nutrient salt solution, optionally containing herbicides, fungicides or insecticides, with an amount of CO.sub.2 effective to economically increase the solubility of said nutrient salt whereby the quantitative uptake through the surface is improved.

Abstract: 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.

Abstract: A method and an apparatus are proposed in order to eliminate the influence f 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.

Abstract: For the purpose of dispensing viscous concentrates, particularly or organic ubstances, a cylindrical pumping space is defined by a hollow cylindrical body and two non-return valves associated with the ends of said body, said pumping space being supported in a radial direction at least during each pumping stroke in such a way that changes in volume are only possible in an axial direction in relation to said pumping space. The metering accuracy capable of being attained by means of the device of the invention makes it possible, with the device being of simple and low-cost construction, to dispense extremely small quantities of a concentrate with the device being operated at a pumping cycle frequency which corresponds to the frequency of the power mains by means of which an electromagnetic actuating coil is operated.

Abstract: 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.

Abstract: An apparatus and a process for carbonating liquids, has inlet pipes for admitting a carbonating gas and a liquid into a container and outlet pipes for dispensing the carbonated mixture from the container. Cooling coils are provided in the container for forming an interior and an exterior surrounding ice layer so that the mixture can come into thermal contact with at least the interior ice layer and be cooled thereby. Electrodes are provided for preventing the thickness of at least the interior ice layer from exceeding a predetermined value.
