Title: Improvements in or relating to the manufacture of paper insulated electric cables and paper therefore
IPC: H01B3/48
Filed: 1922-10-25
Abstract: 203,566. Hydroloid, Ltd., (Exportingenieure f³r Papier und Zellstofftechnik Ges.). Oct. 25, 1922. Electric insulating paper; paper, treating with special materials.-In the manufacture of paperinsulated electric cables, and of paper therefor, the paper, before application to the cable as a spiral covering, is impregnated with a sizing material such as animal size, casein, albumen, or dextrin, by passing it first through a bath of impregnating solution to cause a partial impregnation, then between pressure rolls to press the sizing material into the paper, and then hardened by alum, chrome salts or formalin. The hardener may be mixed with the size, or applied subsequently. To facilitate the absorption of the sizing material, an alkali such as caustic soda, or an acid such as lactic acid, may be added to the sizing bath. Before drying, the paper is cooled with currents of cold air. Glycerine or the like may be applied to soften and toughen the hardened material, and, where the material is to be subjected to rough treatment, an oil varnish may be applied after the glycerine. The addition of an easily emulsifiable material such as soap or castor oil to the sizing bath renders the treatment with glycerine unnecessary. The paper may be applied to the conductor in a wet condition, and the moisture driven out by passing the covered conductor through a hot impregnating bath; or the dried paper may be treated with an emulsion of tar, paraffin, or the like, and then applied to the conductor.

Abstract: 208,129. Porsche, F. Dec. 7,1922, [Convention date]. Spindles. - In a lift valve of the muchroom type, which is operated by a rotating cam acting on the stem which is of adjustable length, the two parts of the stem are. locked together by means of the usual spring which returns the valve to its seating. The upper end of the stem 2 is threaded to receive a stem 3 carrying a tappet plate 4 so that the effective length of the stem may be adjusted. The periphery of the plate 4 is notched at 8 to receive one end of .the spring 7, the other end of which is secured in a recess 14 in a sleeve 11 which is prevented from rotating by inwardlyextending projections 13 engaging in notches in the valve stem guide 12. The inner ends of the projections engage or abut against flattened parts of the upper end of the stem 2 which is thereby prevented from rotating in relations to the part 3. The alteration of the length of the stem is effected by detaching the end of the spring rotating the part 3 and inserting the spring in another of the notches 8.

Oct. 21, 1932, No. 29522. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 22, 1932]. [Class 39 (i).] In order to prevent back ignition in a gaseous discharge device an auxiliary electrode 13 is arranged near the anode 2 and is maintained at a potential higher than that of the anode so that residual positive ions present at the beginning of the negative half cycle are absorbed by the auxiliary electrode. The cathode 4 may be heated indirectly, or may be cold, or consist of a liquid such as mercury. The auxiliary electrode may consist of a cylinder surrounding the anode with its end open or closed by a grid ; it is mounted sufficiently close to the anode to prevent the formation of a glow discharge during the negative half cycle. The cylinder may extend some distance towards the cathode. The electrode 13 is connected through a resistance 12 with one end of a transformer secondary 19, a tapping 10 on which is connected with the anode. The resistance absorbs the positive ions and is of such a high value that an arc discharge cannot occur between the electrode 13 and the cathode. A control grid 5 in the form of a perforated cylinder may be provided.
