Abstract: 1390675 X-ray analysis of metal coating ROBERT BOSCH GmbH 9 March 1972 [9 March 1971] 10964/72 Heading G1A In a method of determining the content of aluminium combined with oxygen in a metal coating having a metallic aluminium content and an aluminium in combined form content, the total aluminium content per unit area of coating is measured using an X-ray fluorescence analysis, the quantity of hydrogen developed when the coating is subsequently placed in a lye is determined by using a gas chromatograph and the difference between the two values is obtained to give the required value. Fluorescent radiation from a sample 20 Fig. 2, resulting from the incidence of X-rays from a tube 21 is guided by screens 24 on to a crystal 25 which in effecting spectral dispersion reflects that arising from aluminium at a specific angle on to a counter tube 26. Apparatus for testing by a chromatograph the hydrogen given off when the coating of a sample is dissolved in caustic soda is described with reference to Fig. 3 (not shown). The invention claimed is a recording carrier comprising a strip of insulating material having a metal coating the major component of which is aluminium, which coating is capable of burning out, and is at least 250  thick, and in which at least 15 weight per cent of the quantity of aluminium in the coating vapourized on the strip is present in the form of aluminium oxide and/or aluminium oxide hydrate, the coating containing in addition to aluminium at least one of the elements, cobalt, silicon, germanium, chromium and nickel in amounts respectively of up to I wt per cent of cobalt, up to 2 wt per cent of silicon, up to 9 wt per cent of germanium, up to 10 wt per cent of chromium, and up to 4 wt per cent of nickel.

Filed: 1924-05-08
Abstract: 218,252. Walcker-Luedtke-Hammer Oskalyd Orgelbau Ges. June 25, 1923, [Convention date]. Drawings to Specification. Pipe organs; pipes &c.-In an organ or the like, variations in timbre, in strength, and in pitch relative to the keys, are produced in progression along a rank of pipes pertaining to a stop, so that octave-couplings in the same rank effect combinations of notes, not merely of different pitch, but also of different kinds, and in some cases even of the same pitch. As an example, a rank is described having at the bass end reed pipes of bassoon type, the next higher notes being of vox humana type of a somewhat similar timbre but weaker. These are succeeded by violin diapason flue pipes, the scaling of which is narrowed down in the next group to give a gamba of increasing strength. The next groups give a decreasing string-tone (quintaton), harmonic flute tone, and stopped diapason tone. In the next group each stopped diapason pipe is combined with a 5 1/3 ft. fifth; while in the next a 10 2/3 ft. fifth is combined with a 6<2>/5 ft. third, thus introducing a change of pitch, which, however, is hardly noticeable owing to the variation in timbre. To form the highest group of notes a 16 ft. gamba and 16 ft. voix celeste, both increasing in strength, are added to the pipes, decreasing in strength, of the previous group. A partition, dividing the rank into treble and bass, may be produced at any point.
