Title: Television electronic control circuit for channel selections
Inventor: EVANS WAYNE WHEELER
IPC: H03J5/02
Filed: 1970-05-28
Abstract: 1301129 Counters RCA CORPORATION 28 May 1970 [29 May 1969 30 June 1969 16 July 1969] 25759/70 Heading G4A [Also in Division H3]  In a television tuner in which means are provided for automatically changing the tuning in steps, to preselected channels (see Division H3], oscillator 30, when energized feeds pulses into a binary counter 41, the outputs from which are fed to decade decoder 42; this produces outputs successively on the lines CH2 &c. which energize in turn a set of drivers 48. The drivers 48 successively apply control signals to VHF tuner 82, in which the channels are selected either by means of short-circuiting diodes connected to appropriate taps on the tuning inductors, or by means of varactor diodes. When decade decoder 42 reaches its last output, this is fed to flip-flop 44 to reverse it, whereby power switch 45 is opened, removing energization from decoder 42, and power switch 46 is closed energizing a second decade decoder 43; further pulses from counter 41 then cause decoder 43 to step round channels 10-13, followed by channel "UHF" in which the manually-tuned UHF tuner 84 is brought into operation. The next pulse from counter 41 causes decoder 43 to pass a control signal to flip-flop 44, which is thereby restored to its original state, closing power switch 45 and bringing decoder 42 back into operation, and opening switch 46 and so de-energizing decoder 43.

Title: Catalytic cracking of hydrocarbons having a carbon number of from c to c
Inventor: HUPFER LEOPOLD
IPC: C01B3/38
Filed: 1965-06-18
Abstract: Fuel gas is made by cracking hydrocarbons having a carbon number of C2 to C15 in the presence of steam over a nickel and/or cobalt catalyst which is maintained in two separate temperature zones, the first (which occupies from one-fifth up to four-fifths of the total catalyst volume) being kept at 350 DEG  to 550 DEG  C., and the second (which, however, must be nickel) at 560 DEG  to 1000 DEG  C. Preferred temperatures are 450 DEG  C. and 700 DEG  to 850 DEG  C. respectively, and pressures may range from atmospheric to 100 atmospheres, preferably 20 to 60 atmospheres.  The catalyst in the two zones may be the same or different, e.g. Ni (preferably 35 to 50% b.w.) or Al2O3, ZrO2, MgO, TiO2, or silicate carriers for the first zone, and Ni (preferably 15 to 25% b.w.) on Al2O3, ZrO2, MgO carriers, if desired with an alkali, for the second zone, and this catalyst may be calcined.  A catalyst containing less than 10% b.w. Ni and free of silicates may be interposed between the two zones. All catalysts may have hydraulic binders.  A specific example using a desulphured light naphtha is described.  The invention permits lower steam ratios to be used.ALSO:Cracking catalysts is effected in two stages, a first zone containing less than 10% supported Ni in association with calcium aluminate and a second stage containing 15-30% Ni.  The supports may be Al2O3, MgO, ZrO2.  Silicates are absent but alkalis may be present.  The catalysts may have a surface area of 6-30 m2/gm.

Title: Improvements in process of treating mineral hydrocarbon products
IPC: C10G19/04
Filed: 1933-09-20
Abstract: In processes for the purification of liquid hydrocarbons by alkali, in which the proportion of free sulphur to mercaptans is first adjusted so that the alkali treatment removes the sulphur completely, e.g. as described in Specification 214,733, [Class 91], the alkali used is anhydrous or substantially anhydrous, or is a saturated solution in water or a concentrated solution of alkalies or alkali alcoholates in alcohols, ethers, ketones, or other organic solvents. Residual alkalinity is removed by treatment with dilute sulphuric acid, catechol, salicylic acid, stearic acid, or other acidic reagent.  Specified reagents are sodium hydroxide, potassium hydroxide, calcium hydroxide, a solution of sodium ethylate in ethyl alcohol, and a solution of caustic soda in methyl alcohol.  The alkali-sulphur compounds separated are used in known ways, e.g. in orchard sprays, or may be separated from each other by fractional crystallization or other known process.  In one example, 0,1lb. of sulphur is added to 1 barrel of gasolene containing 0,07lb. of mercaptans; the mixture is agitated with 0,085 gallons of methanol containing 1,9 lb. of caustic soda per gallon.  The sodium sulphide, polysulphide, and thiosulphate produced, and the excess methanol solution of caustic soda are removed, and the alcohol is evaporated off to leave impure sodium sulphide.  The gasolene is treated with 5 lb. of 50 per cent sulphuric acid, and settled out, the aqueous solution of acid and alcohol being distilled to recover the alcohol and leave sulphuric acid.

Abstract: 1351856 Continuous casting TECHNICON INSTRUMENTS CORP 19 April 1971 [13 April 1970] 26266/71 Heading B3F A tubular shell 17 of metal is continuously cast by moving apart a source of molten metal, such as a tundish 12, and a cooled, closed-end mould 14 (e.g. in the manner described in Specification 1,316,607 and utilizing a hollow starter bar 13 fixed to the tundish outlet), molten metal flowing towards the mould through the shell during casting and, after termination of the flow from the source, continuing to flow into the mould to form an additional length of shell. A second molten metal 18 is poured from a ladle 20, as shown, by way of the tundish 12 when pouring of the shell metal is stopped and an intermixed area 21 is formed between the melts. As the relative movement between tundish and mould progresses, the last of the first metal 11 continues to flow through the shell 17 to the mould 14 and is substantially all solidified to complete the shell. Then when the area 21 reaches the closed end of the mould 14, the second metal 18 may progressively solidify in the shell so that a composite billet or slab results, having a core of the second metal. Alternatively, a hollow core may be formed, so that a composite tube results, by separating the tundish 12 and mould 14 along an inclined path with the mould lowermost. as indicated in Fig. 8 of Specification 1,316,607, increasing the cooling by spray-nozzles 19 and continuing the separation of the mould and tundish after the tundish is free of the second metal or its outflow is otherwise stopped. The second metal 18 may be provided by treatment (killing by Al or Si) of part of the first metal 11 (rimming steel) which remains in a ladle after sufficient to form the shell has been poured. A core of carbon steel may be solidified in a stainless steel shell, or vice versa. A layer of alloy may be formed between the shell and core. Cu, Al, Al alloy or bronze cores may be cast in carbon or stainless steel shells and combinations of non-ferrous metals may be cast. The core may have the higher melting point.
