Title: Improvements in multiplex radio systems
IPC: H04J9/00
Filed: 1943-11-15
Abstract: 582,044. Multiplex wireless signalling. PRESS WIRELESS, Inc. Nov. 15, 1943, No. 18998. Convention date, March 12. [Class 40 (v)] In a multiplex system employing a single carrier, one channel for code or facsimile telegraphy is provided by frequency modulation and another channel for voice signals is provided by amplitude modulation, the telegraph signals being rounded to prevent abrupt changes of frequency. In Fig. 1, the carrier generator 2 is frequency-modulated by a modulator 3 controlled by telegraph or like signals from the source 4. The F.M. wave is amplified at 5 and is amplitude-modulated fairly deeply by a modulator 7 controlled by an audio source 6. At the receiver the amplitude modulation is detected by a flat-response receiver 9 preferably wlthout heterodyning and passes to an audio signal reproducer 11. The received wave is also fed to a receiver 10 where it is heterodyned by a source 12 and the output passed through a band-pass filter 13 to a limiter 14, frequency discriminator 15, which may be of the kind described in Specification 580,968, detector 16, and facsimile or telegraph reproducer 17. Before transmission the telegraph signals are rounded to avoid too abrupt changes in frequency. The frequency range after heterodyning by 12 is less than an octave, and the pass band of the filter 13 is correspondingly limited. The receiving arrangement may comprise a pair of diversity-receiving aerials connected to pairs of AM and FM receivers with interconnecting devices for selecting the stronger of the two signals as described for example in Specification 577,247, (Figs. 2 and 3, not shown). In a modified arrangement, the voice signal is frequency-modulated on a subcarrier, and the resultant is amplitude-modulated on the main carrier (Fig. 3, not shown). The limiter 14 of Fig. 1 may be replaced by a radio-frequency limiting stage interposed before the heterodyne stage 12 (Fig. 4, not shown).

Title: Process for improving artificial fibrous material
IPC: D06M11/53
Filed: 1928-07-02
Abstract: 323,731. Lilienfeld, L. July 2, 1928. Yarns, treating with liquids.-The properties of cellulose artificial silks, &c. are improved by treatment with alkaline agents which have a shrinking effect on the threads, at 25‹ C. or higher temperatures. By subjection to the treatment the following changes in properties, not necessarily all at the same time, may occur :-the materials acquire a feel and softness resembling that of natural silk, an improved lustre, a higher elasticity and extensibility especially if the materals are treated in the unstretched condition, a reduced tendency to form creases, an increased resistance to mercerizing-agents, and more level dyeing properties. Suitable alkaline agents are solutions of caustic alkalies particulaly of 5-40 per cent strength, alkali sulphide solutions of 15 per cent or higher strength, and solutions of quaternary ammonium bases, organic bases such as guanidine, and sulphonium hydroxides. To the solution of the alkaline agent there may be added other agents such as sodium chloride, sulphate, silicate, aluminate, zincate, phosphate, or acetate, borax, or an alcohol such as ethyl alcohol or glycerine. The materials treated may be cellulose artificial silks, staple fibre and artificial hair, straw or wool, whether made by the viscose, cuprammonium or nitrocellulose processes, including that modification of the viscose process in which coagulation is effected by sulphuric acid of 50 per cent or higher concentration, or by another mineral acid of equivalent strength, as is described in Specifications 274,521, 274,690, and 281,351, [all in Class 2 (ii), Cellulose &c.], they may be treated in the form of threads, yarns in skeins or cops or as warps; and with the cellulose artificial silks &c. there may be mixed other fibres, such as cotton or other mercerizable fibres, or silk or wool, the latter being suitably impregnated to protect them against the action of the alkaline agent. The treatment may be applied to the materials in the completely finished condition, or during manufacture of the artificial silk &c. at any stage after the coagulation or fixation has been completed. In examples, ordinary viscose silk and viscose silk that has been coagulated by 50 per cent or stronger sulphuric acid, are treated with solutions of caustic soda of strengths between 7 and 75 per cent at temperatures ranging from 25 to 150‹ C., and with sodium sulphide solutions of 58-100 per cent strengths at temperatures of 50‹ and 100‹ C., the treated materials being subjected to the action of boiling water or 10 per cent sulphuric acid. Specifications 253,853 and 281,352 also are referred to. According to the Provisional Specification the treatment may be applied to cellulose acetate silk &c. in which case caustic alkali solutions of more than 30 per cent strength or alkali sulphide solution of 84-100 per cent strength are used.

Title: Improvements in or relating to the clarification and stabilisation of beer
IPC: C12H1/048
Filed: 1964-05-11
Abstract: Beers are stabilized, and their clarity and flavour are retained during packaged storage, by adding to wort or fermented beer prior to final filtration a non-swelling particulated adsorbing agent containing at least 70 per cent by weight of calcium silicate, magnesium silicate or zinc silicate, removing the adsorbing agent and packaging the beer.  The silicate is added to the wort or beer in a proportion between 50 and 2000 parts per million and the addition is preferably made in combination with a filter aid either immediately before, or actually during, the filtering step. The silicate should contain at least 15 per cent by weight of CaO, MgO or ZnO (as the case may be) and have less than 2 per cent of TiO2, 5 per cent of Fe2O3 and 5 per cent of Al2O3 as impurities. There may be employed synthetic, hydrothermally-formed, hydrated silicates of average particle size less than 20 microns.  The silicates may be added during wort boiling, wort storage, fermentation, beer storage or aging. Protein modifying enzymes such as papain, ficin, bromelin, pepsin, trypsin and crude preparations or extracts from fungal or bacterial sources such as Aspergillus oryzae and Bacillus subtilis, in proportions of between 1 and 1000 parts per million of the wort or beer, and amylases, fungal pectinases, cellulases and hemicellulases may also be included with the silicate, giving a synergistic effect. However, the enzymes should be added after wort boiling.  In examples there were employed acid magnesium silicate (containing at least 70 per cent by weight of MgO and SiO2) and a synthetic hydrated calcium silicate.
