RECEIVER Filed Oct. 16, 1930 mVENToRS ram; ggnmc Y aw TORCH 'AfioRNEY Patented May 10, 1932 1' UNITED STATES PATENT OFFICE FRITZ DOBING, OF BERLIN-FBOHNAU, AND PAUL B'IORGH, OI BEBLIN-CHARLOTTM- BURG, GERMANY, ASSIGNORS TO SIEMENS & HALSKE, AKTIENGEELLSGHAIT, OF BIEMENSS'IADT, NEAR BERLIN, GERMANY, A CORPORATION 01 GERMANY CHEMICAL PICTURE TELEGRAPH? RECEIVER Application filed October 18, 1880, Serial Io. 489,028, and in Germany September 18, 1989.
The chemical picture-telegraphy receivers known in the pr1or art utilize a picture carrier or support made of paper which priorto its actual use is moistened with an electrolyte, preferably an iodide of potassium solution. Hence, unless the moistening is to be accomplished in the most sim le manner by hand, means must be provi ed for the purpose of moistening the picture carrier as briefly as feasible rior to its passage into the inking or recor ing device, with the electrolytic liquid. However, such moistening must be effected in a very careful manner because unduly'copious moistening would cause the .signals to be blurred, while, on the other hand, in case of deficient moistening, the ensuing unduly high electrical resistance would make the resultant picture points too feeble.
The same conditions will arise if, according to another prior art method, the picture support is introduced in prepared,"
though dry, state in the receiver, and if moistening takes only place with water a short while before use by a similarly built arrangement as before described. New, such moistening device renders the construction of the receiver apparatus complicated, and tends to render the equipment not only expensive, butalso unsafe in actual operation.
According to the present disclosure, the said difiiculties, as regards insurance of proper degree of moisture and simplicity of design, canbe obviated. by storing the available quantity of the picture carrier inside a storage drum or the like in a condition ready for use and thus moisten to the proper degree. It is thus feasible to maintain the degree of moisture of the paper at a constant and accurate value, while, on the other hand, making the construction of the equipment as simple as possible, seeing that supplementary and disturbing moistening means in the neighborhood of the inking electrode can be dispensed with. The non-prepared or prepared, though dry, quantity of stored material, by the aid of a simple arrangement adapted to moisten the picture support, may be imparted and given the correct degree of moisture, or else the ready and priorly moistened support may be introduced in such moistened condition into the drum and thus be used.
In this latter scheme it is feasible "as" sell the storage spool in a suitable sheath or en- .velope in moistened state ready for use. For
manufacturin such a support sold in a condition ready or use it is recommendable to apply the moisture upon the support in such a way that the paper impregnated with a solution of potassium iodide or the like is dried and inserted into the container or en- -velope.v The en rt inside the said envelo e is thereupon su ected to the action of a et of steam for some time until the steam has permeated the preferably wound support.
By sudden cooling the steam inside the said envelope is then caused to condense so that the moisture finds a chance to become imparted to the 'su port while becoming incidentally uniform y distributed. The en velope is then shut hermetically and sold. The envelope may consist of an hermetically closing metallic or ceramic container. However, it has been found to be particularly desirable to manufacture the container fronr parafiin wood. with a view to simplifying and ed paper or from thin parafiined adapted to ull the beginning of the paper strip theret rough, said slit to be shut by a strip of pasted paper or the like to prevent evaporation of the moisture. By pulling the support paper strip, the strip of paper used for closing the slit will come ofi so that the spool can be used. The slit of the spool to preclude evaporation of moisture during use, may be provided with felt packing through which the tape is pulled. The packing container within the-telegraph apparatus may be mounted inside another casing.
The novel arrangement here disclosed is suited both for picture-telegraph equipments with transverse exploration as well as for aligned with the slotted portion of the inner those havinga picture support mounted upon housing, the inner housm and the recorda drum. mg paper being supportecf within the outer Figs-1 and 2 show two embodiments of the hOllSlllg, and a fibrous bearing surface carinvention b way of example, Fi 1 showing ried b the outer housing in the slotted por- 7 a storage rum in which the nished and tion t ereof at the point where the recordready picture carrier or surface is marketed, ing paper is withdrawn for recording purand Fig. 2. showing sectionally the arrangeposes. ment of the storage drum inside a picture In te timony whereof We afiix our signa- 10 telegraph equipment. tures. 76 Referring to Fig. 1, the storage drum is FRITZ DORIN G. denoted by 1 inside a can 3 being hermetical- PAUL STORCH.
ly closed by a cover 2. The storage spool is located upon a spindle (not shown) upon one end of which closely adjacent to the storno age spool there is di osed a moistened sponge, wick, or the like 4. The container is properly closed by the lid so that the confined moisture will be unable to escape therefrom.- If the picture support 1 has been ins5 troduced or canned in dried state, then within a certain length of time, at any rate, until the paper is to be employed, it will be kept moistened perfectly uniformly so that until the end of the storage quantity perfect picf 90 ture carrier material willbe available. 4 lhe lid 2 maybe crimped or soldered onto the can in well-known manner or simply be very snugly fitted to the wall of the container. The wick4 may be impregnated with water 95 (in case a prepared or emulsified support is used) or else with an electrolytically acting solution such as potassium iodide, in case the support is non-impregnated. Referring to Fig. 2, the storage drum 6 100 is shown rotatably supported inside an outer casing 5. As can be seen from Fig. 2a, 1 the stored paper spool 7 is also revolubly supported inside of the drum 6, the paper in 1 moistened state being unwound from said 10's spool through. the outlet slits being lined with packing material '8 consisting of felt or the like. The outer housing 5 is provided with additional pieces of felt 11 at the '45 outlet point of the paper strip. After issuno 'ing through the said slit of the outer casing, the strip in moistened condition is conducted along the blade-shaped electrode 9 and operated by the cooperative electrode 10. I Inside such a storage drum or can the preliminarily moistened paper keeps for several weeks in perfectly serviceable condition withj out subsequent moistening or the like being necessary.
