Abstract: 729,917. Electric incandescent lamps. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R. T. Sept. 12, 1951, No. 21487/51. Class 39 (2). To prevent arc discharge within the bulbs of electric incandescent lamps a composition comprising at least two oxides of the elements of the main or sub-Group IV of the Periodic System with the exception of carbon, e.g. SiO 2 , GeO 2 , or TiO 2  is provided inside the bulb, preferably in the form of a layer applied to the inner surface; part of the SiO 2  or GeO 2  may be replaced by SnO 2  or PbO 2 . In addition the composition may include an oxide of a Group III element, e.g. B 2 O 3 , or small amounts of an oxide of the rare earths, or of the vanadium group and WO 3 . In order to utilize the ultraviolet radiation from the filament, small quantities of a fluorescent powder or powdered mixture may be applied in known manner, before, after, or simultaneously with, the application of the oxides. Examples of the applied compositions comprise SiO 2  95 per cent, GeO 2  5 per cent, SiO 2  96 per cent, TiO 2  4 per cent, or TiO 2  90 per cent, SiO 2  10 per cent. A layer consisting of SiO 2  and GeO 2  may be obtained by vaporizing the esters of the two elements within the bulb, e.g. tetraethylsilicate and either the corresponding germanium compound, or a mixture of alkyl chlorsilane and alkyl chlorgermane under simultaneous oxidation in air or in oxygen. A thin layer of a thickness not exceeding one micron may be thus obtained. The quantity of the oxides applied to the bulk should not exceed 4.5 milligrams per square centimetre. In some instances the application of the getter material may be facilitated and the fineness of the particles improved by using halogen compounds, such as alkyl chlorsilane or by vaporizing and oxidizing the substances in the presence of a compound containing a halogen such as chloric acid gas. Alternatively the layer on the inner surface of the bulb may be applied together with a binding agent, preferably organic. For example the finely divided oxides are mixed with a colloid or a synthetic material such as a polyvinyl derivative or a synthetic resin such as synthetic silicone resin, or with a solution of any one of such substances, e.g. collodion, polyvinyl acetate or silicone resin. A suspension of the substances may be applied to the inner surface of the bulb and the binding agent removed by burning, or converted into a compound which does not affect the working of the lamp.

[Also in Division G4] In a code converter, an input character is compared with characters produced by addressing a sequential network with a sequence of possible output characters, that of the latter causing equality in the comparison or producing a void character from the network being supplied to the output, means being provided to change the state of the sequential network on production of a void character. A sequence of input characters can be converted as above, for applications involving secrecy and to reduce storage space requirements in a storage system. Forward conversion (Fig. 8).-A row of a matrix SN can be selected through a decoder ZL-DEK by a character s, and a column can be selected through a decoder SPA-DEK by a character y. The cross-point thus selected delivers a character s and a character z. For each input character e in turn, a series of possible characters y select successive columns of the matrix SN in turn, the values of z obtained being compared at VGL with the current e and also tested to see if they are void. (At least one y of the series, y 0 , produces such a void z). On equality or detection of a void z, the current y is stored in a result register RES-REG, and the s just obtained from the matrix replaces that previously used for selecting a row of the matrix. (The initial value of s, viz. sj 0 , used for this purpose is prespecified.) The series of characters y then starts again from the beginning, the value of e used being the same in the case of void z and the next to be converted in the case of equality, void taking precedence over equality. Reverse conversion (Fig. 10, not shown).- An identical matrix is used, the input characters being used in turn to select a column, each s obtained replacing that previously used for selecting a row. Any non-void z obtained is stored in a result register as the output.
