Title: Process and Apparatus for the Preparation of Gases containing Hydrogen and Carbon Monoxide
IPC: C01B3/36
Filed: 1967-12-18
Abstract: 1,165,440. Steam reforming hydrocarbons. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 18 Dec., 1967 [20 Dec., 1966], No. 57364/67. Heading C5E. Gases containing hydrogen and carbon monoxide are prepared by the partial combustion of hydrocarbons in a reaction chamber comprising one or more burners to which the hydrocarbons and an oxygen-containing gas are supplied, a first zone located near these burners and in which the combustion gases from the burners are thoroughly mixed, and a second zone which comprises at least three theoretical mixing stages and in which the reaction is completed whilst the conversion of soot to gaseous compounds is promoted. A suitable apparatus has a burner 3, a first zone 1 which is cylindrical and has a length to diameter ratio of at most 6: 1, a second cylindrical zone 2, coaxial with the first zone, having a diameter of 0À5 to 0À8 times that of the first zone and a length such that this second zone comprises at least three theoretical mixing stages. The length of the second zone may be between 1 and 5 times the diameter of the first zone. Mixing of the gases in the first zone may be promoted by introducing the hydrocarbons and/or oxygen required for the combustion in such a way as to make the combustion gases rotate about the centre line of the zone. In the example, 100 tons of hydrocarbon per day are reacted with 120 tons of oxygen and 50 tons of steam at a temperature of 1300‹ C. and a pressure of 35 atm. in an apparatus wherein the first zone has a diameter of 1 m. and a length of 1À35 m., the second zone has a length of 3 m. and a diameter of 0À6 m., and the conical connecting section has a length of 0À25 m.

Abstract: 1356553 Channel section circuits; gating circuits TOKYO SHIBAURA ELECTRIC CO Ltd 14 Dec 1972 [16 Dec 1971 31 March 1972] 57742/72 Headings H3Q and H3T [Also in Division G3] A channel selecting apparatus comprises switches SW1-SWn for selecting DC voltages for each channel, first diodes D1-Dn connected at one end to the selective D.C. voltages and connected at their other ends 21 collectively so as to conduct the selected D.C. voltage to variable capacitance diodes of an electronic tuner 22, a second diode Do common to the first diodes and having substantially the same temperature and voltage-current characteristics as the first diodes and connected in series with and opposite polarity to the first diodes between the common connection 21 of the first diodes and the variable capacitance diodes and means having a first constant current source 25 connected to the side of the second diode Do connected to the capacitance diodes and a second constant current source 27 connected to the other side of the second diode. The second constant current source 27 generates a constant current substantially twice that of the first constant current source 25 thereby providing an equal amount of constant current in the forward direction to any of the first diodes D1-Dn which is in a conducting state and also to the second diode Do. The diode Do compensates for changes in voltage with temperature introduced by the conducting diode D1-Dn. The channel voltage selected by the selected variable resistors VR1-VRn occur at the point 23 uneffected by temperature. The channel selecting switches SW1-SWn may be mechanical or transistors such as FET's. The constant current sources 25, 27 are controlled by biasing transistors Q1 and Q3. The diodes D1-Dn and Do and the constant current circuits can be formed as an integrated circuit. A VHF-UHF tuner connected to 23 is disclosed (Fig. 4, not shown). The diodes D1-Dn and Do may be connected opposite to that shown (Fig. 5, not shown) and the switches SW1-SWn may be connected between earth and an end of the variable resistors VR1-VRn. Modified constant current sources for source 25 are disclosed (Figs. 6 and 7, not shown) using a lateral transistor (Q11) in an integrated circuit. In a modification of one of these constant current sources (Fig. 8, not shown) a differential amplifier (D.A.) is used to obtain a more stable constant current characteristic. The channel selecting apparatus may be applied to a T. V. or FM radio tuner.

Abstract: 1,240,477. Mosaic printers. CREED & CO. Ltd. 13 Dec., 1968 [20 Dec., 1967], No. 57878/67. Heading G4H. In a printing system of the kind where each line of mosaic characters is built up by recording successive rows of dots on a moving surface, a complete line of characters is placed in store C and the rows of dots are formed by repeatedly reading out the characters successively to a code-to-mosaic converter, switching the output of the converter to successive groups of recording heads in turn the first read-out causing the first rows of all the characters to be recorded, the second read-out causing the second rows to be recorded and so on. The characters in serial 5-bit telegraph code are received by a series-toparallel converter A and transferred in parallel form to store B. A complete line of 100 characters is stored in B each in a 5-bit store. When a complete line is stored, the signals are transferred to the buffer store C. The characters are formed from a pattern of dots, each being part of a matrix of ten rows and seven columns. To record each character therefore a series of signals must be developed for each row. The characters read out in turn from store C are recoded at D to a signal on one of 96 leads defining the character, and this signal enables a converter E to generate the signals for the first row during the first read-out, the signals for the second row during the second read-out and so on, the 100 characters of the line being treated successively. The output signals from converter E is applied to 100 groups of seven recording heads arranged in a row across the record surface. This may be a magnetic drum, or alternatively recording may be electrostatic. The circuits are controlled by a unit G which is controlled in turn by timing pulses derived from a disc rotating with the drum.
