Patent GB-367782-A (GB)
Title: Process of producing floor coverings
IPC: D06N7/04
Filed: 1930-11-18
Abstract: Coloured floor coverings are made by mixing in the cold colouring matter, e.g. carbon black, dye powders or solutions, mineral powders, and a known bituminous emulsion in which humic, lignic or silicic acid, certain specified salts of these acids, or silica gel, is used as emulsifying agent instead of soaps or alkalies.  A hydraulic binding agent such as cement, lime or plaster may be included.  After the composition has been applied and smoothed it can be rendered glittering by the application of a paraffin emulsion.  In an example, a grey floor with reddish blue marbling is produced by mixing quartz powder, sand, basalt slack and cement with an asphalt dispersion and then mixing a portion of this with red ochre and the remainder with ultramarine blue.

Filed: 1961-09-27
Abstract: 953,135. Television; transmission systems. MINNESOTA MINING & MANUFACTURING CO. Sept. 27, 1961, No. 34732/61. Headings H4F and H4R. [Also in Division G5] In a signal transmission or recording system, a frequency band liable to noise is separated out, compressed and then recombined with the remainder of the signal. Corresponding inverse operations take place in the receiver or reproducing system. As shown, signals from a source 1 feed a low-pass filter 5 whose output is linearly amplified at 13. The signals are also fed to a delay line 7 whose delay is equal to that of the filter 5. The outputs from 5 and 7 are fed to a differential amplifier 9 whose output thus represents the high-frequency component only. This is fed to an instantaneous compressor 11 whose output is proportionate to a fractional power (preferably 1/2) of the input. The uncompressed low frequencies and the compressed high frequencies are combined at 15 for recording at 19. At the reproducer the signals from the pick-up after passing through an equalizer are fed to a circuit similar to the above with the exception that the circuit 11 is replaced by an expander having a power law whose exponent is the reciprocal of that at the recorder (and is therefore preferably 2). In colour television the mixed highs will be those subject to noise and therefore sent or recorded in the band using compression. The mixed highs may then be added to each colour channel in which case they are added individually on reproduction. Alternatively the mixed highs may be sent on one colour channel only in which case they must be added to all the colours on reproduction.
