Title: Improvements in and relating to wireless receiving sets and radio gramophones
IPC: H01F27/00
Filed: 1931-10-12
Abstract: 391,473. Inductances. POLLACK, A. J., Loretto House, Heaton, and ROBERTS, E. H., 39, Scholemore Lane, both in Bradford, Yorkshire. Oct. 12, 1931, No. 28239. [Class 37.] In a wireless receiving set, for changing the wave-range, coils for tuning to long and short wavelengths are carried in drums or casings ganged together on a common shaft, the casings carrying the necessary contacts for engaging with contact fingers connected to condensers closely adjacent to the coils. Auxiliary contacts for switching over for gramophone operation may be added. In the arrangement shown, three drums D containing the coils are mounted on a common spindle, studs C or the like connected to the respective tappings of the coils being fixed on the outer surfaces of the drums, and adapted to coact with fingers F connected to the condensers (not shown). To change the connections, the drums are partially rotated together, for example by means of an arm A connected to one of the drums and to a disc B which is mounted on a shaft S passing through a tuning dial T. The latter may carry means for operating a main switch or a gramophone switch. Instead of arranging the drums for rotary movement, they may be so mounted that the change of connections is effected by shifting them sideways. Specifications 276,867, [Class 37, Electricity, Measuring &c.], 308,902, [Class 40 (v), Wireless signalling &c.], and 370,409 are referred to.

Alkalies and cellulose, obtaining; band conveyer apparatus. - An electric current is passed through the coagulating bath used in the manufacture of films from cellulose solutions in such a manner as to produce at the point at which the film enters, a bath having an alkaline reaction, at an intermediate point a bath of neutral reaction, and at the exit a bath of acid reaction. For this purpose the tank 1, Fig. 1, holding the coagulating bath is provided with electrodes 2, 3 of metal, graphite, carbon, etc.; the film to be coagulated is applied to a con. veyer band 4 which is passed through the bath in a series of loops by means of rollers 5. For viscose, cuprammonia-cellulose and solutions of cellulose hydrate a solution of sodium sulphate is a suitable coagulating bath. The film may be dyed by the addition of a dye to the coagulating bath, use being made in the dyeing process of the electric current; thus by choosing an acid dye that tends to migrate to the anode, the dye is forced to pass through the film and to be taken up by it; acid and other dyes soluble in alkali but insoluble in acid are suitable for this purpose.

IPC: C10L9/08
Filed: 1961-08-08
Abstract: In a process for producing petroleum coke from a heavy petroleum residuum, coke fines produced are recovered and injected into the coker feed during the coking step.  The delayed coking process is employed, in which the bottoms from a fractionator 5 are passed through a heater 15 to a coking drum 16 or 17 at a temperature of 910 DEG  to 925 DEG F., and after cooling, crushing and <PICT:0929007/III/1> screening, the coke is delivered to a silo 19 and a rotary kiln 21 for calcining at 2500 DEG F.  Gases from the kiln 21 carry coke fines to a cyclone separator 27, which may be wet or dry, the fines being passed to a drum 31 where they are formed into a slurry with an oil, e.g. gas oil from the fractionator 5.  The slurry is delivered through line 33 to the drums 16, 17.  Fines from areas other than the separator 27 may be employed, e.g. wet or dried fines resulting from removal of coke from the drums 16, 17 may be slurried, as may fines from the feed end 20 of the kiln 21. Alternative to slurrying, fines may be fluidized with a gas, e.g. superheated steam, for delivery to the drums 16, 17.  Three examples are described, giving percentages of fines, operating temperatures and pressures, and the introduction of slurried fines with the feedstock through a line 1 is mentioned.

Title: The manufacture of symmetrically substituted azobenzene compounds
IPC: C09B29/00
Filed: 1932-10-14
Abstract: Azo dyes and intermediates.--Symmetrically substituted azobenzene derivatives, which are dyestuffs or are intermediates for the preparation of azo dyestuffs, are obtained by reducing in an alkaline medium a 1-nitro-4-halogenbenzene-3-sulphonic or carboxylic acid to the corresponding 4 : 4<1>-dihalogenazobenzene-3 : 3<1>-disulphonic or dicarboxylic acid and replacing the halogen atoms by amino or hydroxy groups by known methods.  Alternatively, the reduction may be carried further to produce the hydrazo compounds which are then oxidized to the azo compounds before replacing the halogen atoms. The following examples are specified.  (1) 5-Nitro-2-chlorobenzoic acid is dissolved in caustic soda solution and zinc dust is slowly stirred in while keeping the temperature below 50 DEG  C., the mixture being then heated during 2 hours to 90 DEG  C. and maintained at this temperature for 8 hours; the mixture is then filtered hot and the sodium salt of 4 : 4<1>-dichloroazobenzene-3 : 3<1>-dicarboxylic acid is salted out from the filtrate and is heated under pressure for about 10 hours at 150 DEG  C. with caustic soda solution containing some copper powder or a suitable copper compound; the excess of alkali is then neutralized and the sodium salt of 4 : 4<1>-dihydroxyazobenzene-3 : 3<1>-dicarboxylic acid is salted out. (2) 5-Nitro-2-chlorobenzenesulphonic acid is dissolved in aqueous ammonia, zinc dust is added while keeping the temperature below 60 DEG  C. and the mixture is heated during 2 hours to 90 DEG  C.; the mixture is then filtered, air is blown into the filtrate to oxidize the 4 : 4<1>-dichlorohydrazobenzene-3 : 3<1>-disulphonic acid and the sodium salt of the azo compound is salted out; this product is heated under pressure for 8 hours at 160 DEG  C. with aqueous ammonia, whereupon the excess of ammonia is driven off and the sodium salt of 4 : 4<1>-diaminoazobenzene-3 : 3<1>-disulphonic acid is salted out. The Specification as open to inspection under Sect. 91 comprises also the production of similar symmetrical azo compounds in which the benzene nuclei are further substituted, e.g. by alkyl.  This subject-matter does not appear in the Specification as accepted.

Title: Television camera circuit
IPC: H04N5/06
Filed: 1966-06-28
Abstract: 1,144,503. Television. AMPEX CORP. 28 June, 1966 [28 June, 1965], No. 28947/66. Heading H4F. The invention relates to a television camera circuit in which the horizontal and vertical blanking and synchronizing pulses are developed from corresponding deflection pulses which are applied to the horizontal and vertical deflection means of the camera tube. In the case of the horizontal blanking and synchronizing pulses, the horizontal deflection pulses which are obtained from a pulse generator generating single half-wave sine pulses at an appropriate frequency are fed to trigger a first square wave generator to provide the horizontal blanking pulses and to a clipping circuit which passes the tips of the sine pulses to a second square wave generator to develop the horizontal synchronizing pulses. The horizontal synchronizing pulses thus formed occur during the middle part of the horizontal blanking pulses and these pulses are combined to form combined blanking and synchronizing pulses having front and back porches. For the vertical blanking and synchronizing pulses the square wave pulses produced in the vertical deflection circuit are used to trigger said first square wave generator to develop the vertical blanking pulses. Simultaneously these pulses are differentiated and clipped and the clipped pulses are fed to said second square wave generator to develop vertical synchronizing pulses of shorter duration and beginning at the beginning of the vertical blanking pulses. The beam of the camera tube, e.g. a vidicon, which is caused to scan by the deflection pulses, is cut off by the blanking pulses, and the video signal so obtained is mixed with the horizontal and vertical blanking and synchronizing pulses to form a composite video signal.
