SELWIG & LANGE in BRAUNSCHWEIG. Innovations in osmosis devices.

Patent addition to No. 15060 of August 22, 1880.

Patented in the German Empire on September 16, 1881. Longest duration: August 21, 1895.

The device of the ^{eight-way faucet described in the 1} main patent, used to switch the water and molasses flow to osmosis devices, to which the patent claim i. This partially extends, makes it possible to connect all frames through the upper channels with the water inlet funnel at the same time, so that when water is introduced into this funnel and the two drain cocks are opened accordingly in all frames for the purpose of easy and thorough cleaning it receives a downward flow of water from the debris deposited in it, etc.

However, as experience shows, this purpose is only imperfectly achieved if one, as it often happens, instead of the inconvenient and often renewed string cover the frame in support of the pergi ·; -. nt paper inside the same horizontal, provided with some perforations for the passage of water or molasses Attaches wooden sticks by removing the dirt or other precipitation that has settled on the Deposit the surface of these rods, also because of a downward flow of water the too low speed of the same are not sufficiently removed. It must therefore in this case the frames are often thoroughly cleaned by washing the rods.

Such a periodic thorough cleaning of the frame is, however, completely superfluous, and the one purpose of our tap construction, easy and convenient cleaning of the frame, just by Rinse out completely as soon as one spirals in support of the parchment paper (made of metal or another suitable material), which are stretched inside the frame are, applies. They do not hinder the circulation of water and molasses in any way, and they have too little Surface as if a considerable precipitate could be deposited on them; she furthermore have the advantage that the points of contact between them and the parchment paper, which are particularly easy to fill with dirt and so on, only a very short length to have.

FIG. 1 shows an osmosis frame provided with spiral supports in a view, FIG. 2 and 3 the end of a spiral on a larger scale in view and in outline.

The spirals are made of a material that is derived from the salts of molasses or the acidified water used to clean the device, for example will. It is best suited for this purpose brass or copper wire or also heavily copper-plated, nickel-plated or oxidized steel or iron wire. However, you can also do the same Cutting open tubes (made of brass, copper or another suitable material

material, ζ. B. hard rubber and so on) in a spiral line. The spirals are stretched in any direction (preferably horizontally), namely at a distance of 50 to 70 mm from each other within the frame and must then have an outer diameter that is 2 to 3 mm less than the frame thickness. A very convenient way of fastening in the frame is the one shown, in which the two spiral ends are bent into eyelets, which are hooked onto metal hooks that are screwed into the wooden frame from the inside. Instead of simple spirals, one can of course also use double or triple spirals, instead of spirals flattened with a circular cross-section, which have a greater height than width. Likewise, the individual turns of the spirals lying parallel next to one another can be intertwined respectively. penetrate each other. The simultaneous connection of the two upper circulation channels with the water inlet funnel, as well as the two lower circulation channels with the molasses inlet funnel, which makes the cleaning of the osmosis frame so much easier, can also be used with osmosis devices that have two four-way taps to switch the water. and molasses run are easy to manufacture. As is well known, the upper of these two taps, the handles of which may be connected to each other so that their chicks turn at the same time, is with the water inlet and molasses outlet funnel and the two upper channels, while the lower one with the molasses inlet and outlet the water discharge funnel and the two lower channels of the apparatus in connection. If these two taps are given essentially the same construction as the upper (or lower) part of the reversing tap H described in the main patent, the same connection is obtained between the water and molasses inlet funnel and the channels of the tap in the middle position of the tap Apparatus like through this tap. Fig. 4 shows a four-way tap (for example the upper one) set up in this way in a view, Fig. 5 in cross section. The rear outlet of the same communicates with the water inlet funnel (with the lower tap with the molasses inlet funnel through me), the two lateral exits n3 and / 3 with the two upper circulation channels; The molasses discharge funnel is connected to the front outlet ma (the water discharge funnel at the lower tap). As a result of the fact that, as Fig. 5 shows, the junctions of the outlets 3 and / 3 in the tap housing are closer to the inlet we than the outlet ma, they are only partially through in the middle position (the one shown) of the plug the web i of the same closed, while on the other hand ma is blocked. In this position you have the desired connection between the two inlet funnels and the channels of the apparatus, in which, as indicated by the arrows, the water from the water inlet funnel into both upper channels at the same time, from the molasses inlet funnel into both lower channels enters, while there is no connection between the two discharge funnels and the channels of the apparatus. Patent claims: 1. Stretched out in the frame of osmosis apparatus Spirals to support the parchment paper. 2. On four-way taps to switch the water inlet and molasses outlet or the Molasses inlet and water outlet on osmosis apparatus the device which it enables the water inlet funnel to run through the same at the same time as the two upper circulation channels or the molasses inlet funnel at the same time with the two lower circulation channels in connection '. For this purpose I sheet drawings.
