Title: Improved method for preparing and catalytically cracking petroleum residuum fractions
IPC: C10G55/06
Filed: 1954-12-16
Abstract: In a process for the catalytic cracking of petroleum residual oils, the residual oil is subjected to distillation under reduced pressure at an equivalent atmospheric-pressure vapourtemperature of at least 900 DEG  F. whereby a distillate and a residuum fraction are obtained, the residuum fraction is deasphalted with liquid propane, the deasphalted oil and the vacuum distillate are combined, and the mixture is subjected to catalytic cracking. The cracking may be effected using a synthetic clay or aluminasilica type catalyst, arranged in fixed or fluidized beds, at a temperature in the range of 850 DEG  to 1150 DEG  F.  The invention enables a good yield of high-quality gasoline to be obtained from the cracked products, with low catalyst degradation.  In an example, a blend of crude oils from various regions in the U.S.A. was distilled with steam until an 18.3 per cent residuum was produced.  The residuum was then distilled under vacuum in a centrifugal molecular still at a temperature equivalent to an atmospheric-pressure vapour-temperature of about 1150 DEG  F. until a second residuum amounting to 5.8 per cent of the feedstock was obtained.  This second residuum was treated with four parts of liquid propane at 120 DEG  F.  The deasphalted oil was mixed with the vacuum-distillate.  The mixture gave a predicted catalytic yield of C5-430 DEG  F. naphtha of 55 volume per cent.

Abstract: 362,170. Valve amplifying circuits ; filter circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Braden, R. A. ; 18, Jacobus Place, New York, U.S.A.) Dec. 12, 1930, No. 37572. Convention date, Dec. 12, 1929. [Classes 40 (iii) and 40 (v).] A band-pass filter comprises two tuned circuits, variable coupling between the circuits and means for varying the coupling simultaneously with the tuning to maintain the accepted band width constant. The invention is described as applied to a coupling between two valves 1, 8, the inductances 3, 7 of the tuned circuits being tuned by condensers 4, 6 respectively. In one embodiment, Fig. 2, a common coupling condenser 5 is varied simultaneously with the tuning condensers or, alternatively, Fig. 1 (not shown), with the inductances 3, 7. In a modification of Fig. 2, the positions of coils 3, 7 and condensers 4, 6 are interchanged and the filter fed through an auxiliary capacity. A special form of coupling condenser consisting of two fixed plates 9, 10, Fig. 4, between which moves an earthed plate 11 may be used, and where a screen is interposed between the two tuned circuits two such condensers connected in series, and arranged one each side of the screen, may be used to maintain symmetry, Fig. 5 (not shown). The plate 11 may be mounted on the shaft of condensers 4, 6, the plates 9, 10 being fixed to the stators. In another modification, Fig. 6, a coil 13, variably coupled to the first tuned circuit is added to the second tuned circuit, and the coupling varied simultaneously with the tuning. Other modifications include a variable and separate transfer circuit comprising for example coils 15, 16, Fig. 8, and a variable condenser 18. The remainder of the modifications illustrated, utilize arrangements of combined inductive and capacitative couplings, one being in the reverse sense to the other. Curves are given showing that if the inductive or capacitative couplings are suitably fixed, a slight variation of the other coupling suffices to keep the accepted band width constant.

Abstract: 921,527. Direct call loud-speaker systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 4, 1960 [Nov. 5, 1959], No. 37591/59. Class 40 (4). At a loud-speaker substation the transmit or receive amplifier is energized according to the polarity of the energizing D.C. supplied from the master station. When the master station line has L1a negative and L1b positive, rectifier RF2<SP>1</SP> conducts to energize amplifier RA over the split primary of transformer T. Capacitor C1 provides a path for speech to loud-speaker LS from a potential chain across the transformer secondary. When L1a is positive and L1b is negative, rectifiers RF1 and RF3 conduct to supply amplifier SA. Capacitor C2 provides a path for speech in the split transformer winding over a privacy key k. In the amplifier RA capacitor C1 is made large to provide power during peak signal voltages. To protect the substation from howling when SA is switched on and C1 is not discharged a rectifier RF4 blocks the input to RA when SA is energized. The microphone and loud-speaker may be a single transmit-receive transducer.

Title: Improvements in or relating to apparatus for synthesising information signals and tosystems employing such apparatus
IPC: H04B1/66
Filed: 1959-11-10
Abstract: 937,404. Vocoder systems. WESTERN ELECTRIC CO. Inc. Nov. 10, 1959 [Nov. 17, 1958], No. 38054/59. Class 40 (4). In apparatus for rebuilding speech and other signals from one frequency band of the original signal and from signals each defining the amount of energy in other frequency bands of the original signal, a synthetic spectrum occupying at least the major part of the frequency range of the original signal is derived from said one frequency band. At a speech analyzer, Fig. 1, voice currents originating in transmitter T are delivered to band pass filters 10, 11, 12, 13 which pass contiguous portions of the frequency range of the original signal. Filter 10 transmits the lowest frequency band directly to a modulator 20. The remaining frequency bands pass through full wave rectifiers 14, 15, 16 and low pass filters 17, 18, 19 each of which delivers a slowly varying control signal whose instantaneous magnitude is representative of the energy of the associated band the lowest frequency band and control signals are modulated and transposed relative to one another to all lie within the range 300 to 2,770 cycles/second, Fig. 2. At the synthesizer, energy arriving by channel C is separated by demodulators 30, 31, 32, 33 into the corresponding components developed by the analyzer. A portion of the lowest frequency band is fed to an excitation generator 45 which produces a flat spectrum of frequency range corresponding to the original voice currents. The remainder of the lowest frequency band is fed to an adder 38. The flat spectrum is applied to gate modulators 39, 40, 41 which, in accordance with the amplitudes of the control signals, control the application of the flat spectrum to band pass filters 42, 43, 44, the outputs of which are applied to adder 38 to provide a signal representing the original voice currents. Distortion network.-A distortion network for providing the flat spectrum comprises a first diode network 71, 72, 73, 74, Fig. 7, which produces a W-shaped response and a second diode network 66, 67, 68, 69 which provides instantaneous logarithmic compression. The response of the distortion network is shown in Fig. 6. The output of the distortion network is applied to a pulse width converter 48, Fig. 8, comprising transistors 95, 99 coupled by a parallel RC network 97, 98 and which produces square waves of frequency 30 k.c.p.s. The pulse width converter 48 is also fed by a conventional sawtooth oscillator 49 employing a uni-junction diode 83 and a transistor 91. In the pulse width converter 48 one edge of the square waves is modulated by the output of the distortion network 47. The modulated square waves are applied to gate modulators 101, 102, 103. Their outputs are equalized by potentiometers 110, 111, 112, fed through band pass filters 42, 43, 44 and combined in adder 38 with the lowest frequency band supplied from modulator 30.
