Title: Improvements in or relating to speech transmission systems
IPC: H04B1/64
Filed: 1955-10-21
Abstract: 824,259. Bandwidth compression. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 21, 1955 [Oct. 25, 1954], No. 30159/55. Class 40 (4). In a transmission system wherein the signal is subdivided at the transmitter into a number of different formant bands, all except one of the lower bands have their bandwidths compressed before transmission, and reconstitution is effected at the receiver by separating the transmitted versions of the formant bands and expanding the bandwidth of those wherein the original band was compressed. Speech in microphone 1, Fig. 5, after passing through a filter 2 which accepts 300-3200 cycles, is amplified, and transposed by modulator 4 to the range 60.3-63.2 kc/s. selected by filter 6. Bands 60.3-60.8 kc/s., 60.8-62 kc/s. and 62- 63.2 kc/s. are fed to parallel paths 12-14 via filters 19-21 respectively and the latter two are subjected to frequency division in units 17, 18, after passing through amplitude limiters 15, 16. The band of unchanged width is brought adjacent the divided bands by a modulator 24 and the modified band is modulated in a group modulator 8 for transmission over a cable 11. A pre-emphasis network 27 ensures the presence of the higher frequencies in the channels 12-14 after limiting. The amplitude of the divided bands is shaped in units 74, 75 in accordance with the envelopes of the filter output signals. Filters 78, 79 of the envelope detector have a cut-off frequency of less than 40 c/s. The receiver, Fig. 6, comprises channels 39-41 corresponding with the transmitter channels and the latter two include frequency multipliers 47, 48 which return the transmitted band to the width of the original signal. Envelope and level control are effected by circuits 80, 81 responding to detectors 76, 77 and amplitude modulators responding to the signal level in channel 39 respectively. In an alternative arrangement, Fig. 3, the signals in channels 13, 14 are applied to discriminators 60, 61 to control, via units 64, 65, the frequency modulation of oscillators 62, 63. The resulting frequency variation of the oscillator is arranged to be considerably smaller than the bandwidth of the original sub-band. The bandwidth is restored at the receiver, Fig. 4 (not shown), by a similar discriminator-frequency modulator arrangement. Specifications 652,717 and 663,619, [both in Group XL (c)], are referred to.

Title: A new or improved light sensitive film or layer and process for making same
IPC: G03C1/54
Filed: 1922-11-07
Abstract: 210,862. Sokal, S., (Kalle & Co., Akt.- Ges.). Nov. 7, 1922. Plates, films, and papers.-Diazo-anhydrides formed with the separation of water from oxydiazo compounds or from indazol diazo-hydroxide are used as light sensitive layers. Amino salicylic acid or its anhydride are excluded from the scope of the invention. The sulphonic acids of the anhydrides of 1-diazo-2-naphthol or 2-diazo- 1-naphthol or their halogen, nitro, or other derivatives, bisdiazo-p-diphenol, or indazoltriazolen are chiefly used. The yellow diazo compound bleaches and is destroyed on exposure to light. A positive can be produced from a positive (1) by coupling up the unexposed portion with an azo-colour component in the presence of alkali either by subsequent treatment in a bath containing the component and alkali, or by incorporating the component in the sensitive layer with the addition of tartaric citric or like acids to increase stability and coupling after exposure by treatment with ammonia fumes or alkali solution (2) by exposing the whole layer for a short time to light after exposing under a positive, so that the previously unexposed portion is partly decomposed forming an azo colour component which can be coupled up with the still undecomposed portion by treatment with alkali, or by storing for some time in the dark, to give a picture. A positive may be obtained from a negative by adding an alkali or acetate to the sensitive layer, a picture being immediately produced on exposure; the unexposed portion of the layer is then washed away. A mordant, such as tartar emtic, may be added to the layer. The picture produced may be coloured by means of bichromate, and like oxidizing agents. Metal salts, particularly of copper, nickel, iron, manganese, mercury, zinc, and aluminium, may be added to the layer, or to its carrier or to the developing bath, to make the picture fast to water and to produce different shades and colours. Resorcinol, phloroglucinol, or phenylmethylpyrazolone may be used as azo colour components. Specifications 20073/11 and 20073/11, [both in Class 2 (iii), Dyes &c.], are referred to.
