Abstract: For continuous production of dealcoholized beverages, a substrate consisting of fruit or berry juice, grape juice or beer wort is first preclarified in a microfiltration device (2) and sterilized and then fermented by immobilized microorganisms in the fluid bed process in a tower fermenter (3). Support particles (12), which are kept in suspension in tower fermenter (3) and to which the microorganisms are bonded, guarantee an effective biomass retention. After fermentation in tower fermenter (3), the raw juice is freed of alcohol in a dealcoholization device (24) and then clarified in an ultrafiltration or microfiltration device (27). The process taking place in a continuous product line makes possible an especially economical and productive operation of the unit.

Abstract: For selective removal of volatile substances from liquids, the initial liquid is fed to a crosscurrent diaphragm separation device (2), in which the permeate consisting of water and volatile substances is separated by increased transdiaphragm pressure and concentration difference. Then, the permeate is fed into a further liquid-volatile separation device (8), in which the alcohol is distilled out. The permeate now only consisting of water, salts, acids and extracts is then fed back into the crosscurrent diaphragm separation device (2), where it flows through the permeate side in countercurrent to the flow of the retenate. Excess permeate can be introduced into the dealcoholized initial liquid. By the process according to the invention the economic efficiency of the unit and the quality of the end product are significantly improved.

Abstract: For aftertreatment of clarified juices, the juice is brought into contact with an agent, e.g., PVPP, and is filtered in a crossflow filtration device (11) and the aftertreated juice is separated as permeate from the agent. The agent can be regenerated by the addition of water and lye either inside or outside the unit. After regeneration, the lye is again flushed out by diafiltration on the permeate side of crossflow filtration device (11). With the aid of crossflow filtration, the economic efficiency and the universal applicability with respect to the use of agents of the unit can be considerably increased and the treatment quality of the juice can be improved.

Abstract: A compression extractor is disclosed. The compression extractor comprises a tank having a flexible membrane mounted therein. The membrane serves to divide the tank into a mash chamber and a pressure chamber. The mash chamber is adapted to receive a fruit mash or other liquid containing material from which liquid is to be extracted. When a pressure medium is introduced into the pressure chamber, the membrane presses on the mash in the mash chamber to extract the liquid therefrom. A liquid collection system is provided to collect the extracted liquid. To improve collection of the extracted liquid, the side of membrane facing the mash chamber is covered at least in part, with drainage canals or the like to direct liquid located near the membrane to the liquid collection system.

This control track is located in a plane extending essentially perpendicular to the upright or vertical shaft.

Abstract: A hay harvesting machine contains a rake wheel whose housing is formed by an upper housing portion non-rotatably connected with a vertical upright shaft and a lower driven housing portion rotatably mounted at such upright shaft. In bearing bushings rotatably mounted at the lower housing portion there are retained tine supports provided with raking tines or prongs. These tine supports extend in an essentially horizontal plane and, by rotating the bearing portions, can be selectively shifted from a first operating position into a second operating position. In the first operating position the tine supports extend approximately in tangential direction and in the second operation position they protrude essentially in radial direction from the upright shaft. Each tine support is connected with a control lever engaging, by means of a control head or follower, into a control track or cam. This control track is located in a plane extending essentially perpendicular to the upright shaft, i.e. horizontally.

Abstract: A hay harvesting machine containing a rake wheel having a housing formed by an upper housing portion connected non-rotatably with a vertical upright shaft and a lower housing portion rotatably mounted at the upright shaft. The lower housing portion is revolvingly driven by means of a gear drive, typically bevel gearing. In the lower housing portion there are mounted tine supports so as to be pivotal about their lengthwise axis, these tine supports additionally being pivoted about a pivot shaft or axis extending transversely with respect to their lengthwise axis. This pivot axis is located in a plane which is approximately perpendicular to the upright shaft. The tine supports extend in tangential direction and, viewed in the direction of revolving motion thereof, extend rearwardly. For swath formation the tine supports are retained in a pivotal position where they are guided by means of a control head or follower in a control track or cam at the upper housing portion.

Abstract: Disclosed is an aeration device for aerating liquids having a foam-forming tendency. The amount of foam generated by such an aeration device is controlled by having the air inlet disposed at a predetermined foam level. The liquid inlet is disposed near the surface of the liquid to be aerated, such that solid particles floating thereon are taken into the aerator. Air and liquid are combined in the aeration device producing the desired foam. The foam level is prevented from exceeding the level of the air intake due to the fact that air is required to produce the foam, and if the foam level exceeded the air intake, it would be ingested into the pump reducing the amount of foam produced thereby. Particular embodiments disclose concentric foam and liquid intakes to a submersible aeration pump.

The juice outlet arrangement possesses drainage channels at the solid-wall, preferably dome-shaped section of the container located opposite the squeezing diaphragm. The drainage channels are formed by substantially trough-shaped elements provided with perforations and arranged in spaced relationship from one another at the inside of the wall of the container.

Abstract: The present invention relates to an apparatus for the controlling of froth during the aeration of liquids.In the aeration (or treatment with gas) of sewage for the biological (or chemical) purification of the latter it is well known that considerable frothing occurs, which cannot be immediately controlled even with considerable effort and expense, for example using froth skimmers, froth barriers, oversize tanks, and the like. The problem is in providing an aeration apparatus which, without additional measures, that is to say by its own resources, is able to control frothing and thus keep it within permissible limits.The expressions "aeration" and "air" are here used to refer to any gaseous medium which is to be admixed with any liquid concerned in the present context. Similarly the expression "air pipe" is to be understood as meaning a pipe for a gaseous medium.

Abstract: An injection moulding machine used in conjunction with a closed split mould, has its shot volume controlled by a device which responds to widening of the mould parting line occurring when the mould is completely filled with moulding material as a result of the pressure build up which occurs inside the mould. Contactless sensing of widening of the parting line is described, by means of electromagnetic sensing devices. The shot volume can thus be held at the optimum value at which minimum flash occurs and complete filling of the mould is assured.
