Title: Improved manufacture of electric discharge tubes
IPC: H01J9/20
Filed: 1926-03-15
Abstract: 249,847. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. March 28, 1925, [Convention date]. Vacuum tubes.-An electrode for a tube such as a lamp is formed by coating a leading-in conductor and a part of the wall adjacent thereto with a conductive layer, and volatilizing one or more bodies consisting substantially of magnesium to form a deposit of magnesium on the wall in contact with the leading-in conductor. As shown in Fig. 2 a helix 5 of magnesium is mounted on a rod 4 of iron or other material which can be readily deprived of occluded gas. The rod is mounted on a platinum leading-in wire 3 and carries a mica screen 6. A layer 7 of conductive material, such as an emulsion of graphite in water or a binding agent such as aniline, is applied to the lead and on the wall, and the helix is heated by high frequency current induced from a winding outside the tube so that magnesium 8 is deposited on the layer 7 and on the wall. In order to retain and deposit again any magnesium volatilized during operation of the tube, the enclosure 2 for the electrode is made of spherical shape as shown in Fig. 1, and the tube 1 is bent at the ends. In another method the deposit is formed by heating the helix by passage of current, or by a discharge between magnesium electrodes. The filling may be neon at a pressure of a few millimetres of mercury. Specifications 246,538 and 248,023 are referred to.

Title: Improvements in the preparation of sterilising agents, germicides and the like
IPC: C02F1/76
Filed: 1925-03-23
Abstract: 253,623. Harold, C. H. H. March 23, 1925. Treating-materials. - A sterilizing-agent, particularly for treating water and sewage, is prepared by the interaction of aqueous chlorine and an ammonium salt, the ratio of the quantities of the substances taken being from 0.25-2.0 gms. of ammonium to 1 gm. of chlorine. On allowing to stand at ordinary or at elevated temperature, the solution becomes colourless and a relatively concentrated solution of mono or dichloramine or of a mixture thereof is obtained. According to examples, solutions of ammonium monohydrogen phosphate, commercial carbonate. chloride, sulphate and nitrate with aqueous chlorine are employed. With salts of ammonium containing a strong acid radicle, e.g. ammonium chloride, the reaction with chlorine is slow but the chloramine produced is quite stable, while with ammonium salts having a weak acid radicle, chloramine is rapidly produced but is rapidly decomposed unless it is in excessively dilute solutions. Preferably, therefore, a salt containing a moderately strong acid radicle, namely diammonium hydrogen phosphate, is employed. As suitable ammonium salts, however, the oleate, acetate, borate, formate, tartrate, citrate and lactato are also mentioned.
