Title: Improvements in or relating to electric multichannel carrier current communication systems
IPC: H04J9/00
Filed: 1945-10-05
Abstract: 604,230. Multiplex radio signalling. STANDARD TELEPHONES & CABLES, Ltd. Oct. 5, 1945, No. 26050. Convention date, Aug. 19, 1944. [Class 40 (v)] In a multi-channel carrier communication system, a carrier wave of given frequency is modulated in amplitude or frequency by a first signal and a second carrier wave of the given frequency is modulated by a train of phasemodulated pulses, both waves being transmitted simultaneously. In one embodiment, three signal sources 1, 2, 3 are each coupled to modulators 4, 5, 10 respectively. Modulator 4 is a carrier amplitude modulator, 5 is a carrier frequency modulator and 10 produces the carrier keyed by phase-modulated pulses produced in circuit 9 coupled to the signal source 3, for example as described in Specification 600,244. The outputs from circuits 10 and either 4 or 5 are mixed in the coupler 7 feeding the aerial 8. The peak power of the pulse carrier exceeds that of the. continuous carrier to avoid loss of one or both signal components due to possible out-of-phase carrier conditions. The receiving aerial 16 is coupled through R.F. and I.F. amplifier 17 to the pulse demodulator 22 through clipper 18 and detector 20 and through a gate clipping circuit 23 to either an amplitude modulation detector 27 or frequency modulation detector 29. The pulse demodulator may be of the type described in Specification 600,291. The clipper 18 is arranged to pass only the pulse energy occurring above the maximum amplitude level of the continuous wave component of the received signal. The gate clipper 23 selects continuous wave energy occurring between two selected amplitude levels. Any pulse component present in the output of detector 27 is removed by a low-pass filter 28. The carriers of the two channels may alternatively be radiated from separate aerials. Specification 2997/39, as open to inspection under Sect. 91, also is referred to.

Title: Improvements in and connected with belt and like gearing
IPC: F16H7/22
Filed: 1922-09-27
Abstract: 202,541. Howie, R. W. Sept. 27, 1922. Bands, placing on and throwing off pulleys; connecting and disconnecting arrangements; supports for belts when idle.-In belt gearing of the type in which the belt is lifted radially from the driving-pulley for stopping, the pulley 4 is divided at right angles to the shaft 3 and between the halves is arranged a bar 6 provided with a curved end 14 and sliding in guides 7, 8 in the framing. Curved levers 15 are pivoted on the end 14 and connected by links 17 to a rod 18 which slides with end play in a slot in the bar 6 and is actuated by a forked lever 21 connected to a hand-lever 23, movement of which first slides the rod 18 to raise the levers 15 and then slides the bar 6. The belt 5 is thus lifted from the pulley 4. Stops 12, 13 on the bar 6 limit movement in both directions. A tension-pulley 26 may be mounted in bearings adjustable by screws 33 in a weighted lever 27, which may be actuated by tackle 31. The levers 23, 27 may be positioned by pegs 24, 30 fitting series of holes in posts 25, 30<a>.

Title: Improvements in the treatment of materials made of or containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1929-09-02
Abstract: 318,467. British Celanese, Ltd., (Assignees of Platt, H.; and Dreyfus, C.). Sept. 1, 1928, [Convention date]. Yarns, treating with liquids, gases, and vapours. -The lustre of yarns, fabrics, or other materials made of or containing organic derivatives of cellulose, for example cellulose acetate or other cellulose esters or ethers, is reduced by precipitating therein insoluble opaque salts, preferably white, by the interaction of reagents successively applied thereto. Insoluble salts, particularly sulphates or phosphates, of alkaline earth metals, such as barium, calcium or strontium, give particularly good results. The precipitation may be effected by first treating the material with a soluble metallic salt and thereafter with a precipitating agent, the metallic radicles being preferably introduced while the material is in a swollen condition. For this purpose metallic salts which are themselves swelling agents may be employed, for example sulphocyanides of barium or other alkaline earth metals, or swelling agents such as formic acid, acetic acid or acetone may be caused to act upon the material either prior to or simultaneously with the treatment with a metallic salt solution, for example a solution of barium chloride or chlorate. As precipitating agents, aqueous solutions of sulphuric or phosphoric acid or of their soluble salts, such as the sodium, potassium or ammonium salts, may be used. Cellulose ester materials may, in addition, be subjected to a saponification, preferably superficial, either before or after the application of the metallic radicle, whereby they acquire an affinity for direct and acid dyes, while retaining their affinity for the dyes normally applied to cellulose esters and for basic dyes. The delustring effects produced are permanent and are not appreciably affected by ironing or washing, or by treatment with dry steam or other relustring agents. The process may be applied to other cellulose esters besides the acetate, for example the formate, propionate or butyrate, or to cellulose ethers, such as methyl, ethyl and benzyl cellulose, as well as to mixed materials containing other fibres, such as cotton, silk or wool, in addition to cellulose esters or ethers. In examples, cellulose acetate fabrics are (1) treated first with a solution of barium sulphocyanide, then with a 1 per cent sulphuric acid, and (2) treated first with 20 per cent formic acid solution, then with barium chloride solution and finally with 1 per cent phosphoric acid solution.
