Title: Catalytic cracking
IPC: C10G11/00
Filed: 1962-01-11
Abstract: A method for the catalytic cracking of hydrocarbons employs as a catalyst composition a crystalline aluminosilicate with a total hydrogen in content of at least 0.5 equivalents per grain atom of aluminium and a total alkali metal content of less than 0.25 equivalents per grain atom of aluminium, such aluminosilicate being intimately mixed with a matrix. The crystalline aluminosilicates used in this invention are obtained by heating any natural or synthetic crystalline aluminosilicate either before or after its incorporation in the matrix with a fluid medium, preferably water, containing hydrogen ions or ions capable of conversion to hydrogen ions, e.g. ammonium ions until the desired concentration is reached. Long lists of suitable zeolites and clays is supplied. The matrix may be an inert or catalytically active material, and is preferably a siliceous gel matrix. The matrix and the aluminosilicate may be combined in a variety of ways. The siliceous gel matrix may also consist of a plural gel comprising a predominant amount of silica with one or more metals or oxides thereof selected from Groups II, III, IV, V, VI, VII and VIII of the Periodic Table. The cracking activity of the catalyst is illustrated by its ability to catalyze the conversion of a Mid-Continent Gas Oil having a boiling range of 450-950 DEG F. to gasoline having an end point of 410 DEG F. Vapours of the gas oil are passed through the catalyst at temperatures of 875 DEG or 900 DEG F. substantially at atmospheric pressure and a feed rate of 1.3 to 16.0 volumes of liquid oil per volume of catalyst per hour for ten minutes.

Title: Refining of aluminum
IPC: C22B21/00
Filed: 1962-08-03
Abstract: In a sub-halide distillation process for the recovery of aluminium from alloys containing manganese which are solid at the reaction temperature, the sub-halide vapour is condensed in two stages (1) with continuous addition of fresh alloy and removal of spent alloy until a predetermined level of manganese in the effluent is reached and (2) with the supply of fresh alloy, and optionally the withdrawal of spent alloy, stopped, continuing to pass the trihalide vapour until all the aluminium, that economically can be, has been stripped out. The gaseous products of the two stages are condensed separately. During the charging of fresh alloy and withdrawing of the stripped alloy for starting a fresh cycle the trihalide flow is reduced or stopped. Using aluminium trichloride as the reactant the temperature in the convertor is 1000-1400 DEG C. and the condenser is preferably at a temperature of 700-900 DEG C. Two or more condensers may be used to collect the different fractions or one may be used with intermediate emptying between stages.

Patent ES-347152-A1 (ES)
Title: Fuel arrangement for fast breeder reactor
IPC: G21C1/02
Filed: 1967-11-14
Abstract: In a fast breeder reactor, a negative coolant removal coefficient of reactivity is provided by facilitating the leakage of neutrons into the breeding material. The probability of the return of neutrons from the breeding material is reduced and the tendency for the average neutron energy to increase upon coolant voiding is reduced. The fission fuel is distributed in discrete masses uniformly spaced from one another throughout a three dimensional matrix. The fertile material is similarly disposed in discrete masses through the matrix so that each fissile mass has fertile material above, below and at all sides. An increased negative temperature coefficient is produced by the incorporation of a moderator which reduces the average neutron energy and increases the Doppler action. Thorium and U-238 may be used as fertile materials and U233 and Pu-239 as fissionable fuel.
Patent ES-351409-A1 (ES)
Title: Jacquard machine with electromagnetically controlled healds
IPC: D03C3/20
Filed: 1968-03-09
Abstract: An electrically controlled jacquard has hooks 37, 45 formed directly on the healds 13, 14 without the intervention of harness cords, the healds being urged downwards by springs 26 and lifted by griffes 31, 32 engaging the hooks 37. If a heald is to remain up, its hook 45 is attracted by an electromagnet 40 so as to rest on a fixed knife 39. If a heald is to be lowered, it is lifted slightly by the griffe so that its hook 45 springs off, the knife 39. The part 29 of the heald above the hook 37 may be bent slightly to the right so that although it moves to the left when it is engaged on the knife 39, thereby tending to swing the lower part 13 towards 9 guide 38 on the griffe, the tension due to the spring 25 partially straightens the bend thus tending to move the heald away from the guide 38.
Patent ES-352473-A1 (ES)
Title: Wire take-up apparatus
IPC: B65H67/056
Filed: 1968-03-28
Abstract: A strand winding apparatus comprising a pair of take-up reels 22, 23 in spaced axiallyaligned relationship, has a strand traversing device 21 that normally traverses the whole length of a reel 22 but when the major portion of a predetermined length of a strand has been wound up the traverse path is restricted to an area of the reel 22 that is near the other reel 23. The traversing device 21 then moves over to commence the traversing of the strand onto the other reel 23, the strand sliding over an intermediate guide 32 covering the upper periphery of snagger plate 28, 38 carried by the reels, thence over a lower narrower guard 33. Thereafter strand material intermediate the reels 22, 23 passes to a zone where it is snagged by the snagger plates 28, 38. During full traversing, the motion of the traverse 21 is controlled by spaced microswitches LS1L and LS2L but when the motion of the traverse is to be restricted a further limit switch LS1LL takes over from the switch LS1L to limit the traverse motion. The instant at which the further limit switch LS1LL has to be brought in is determined by a pulse generator (17) Fig. 1 (not shown), giving an output signal when said major length has been reeled. The speed of a take up spool is controlled electrically by a rheostat (27) responsive to the state of a strand accumulator.

Title: Vehicle velocity measuring system employing adjustable width pulse generating system
IPC: G01P21/02
Filed: 1968-06-22
Abstract: The speed of a vehicle is measured by an AC tachogenerator whose signals are converted to a train of double frequency pulses of constant amplitude and duration which are averaged to provide a measure of the speed. The pulse duration is adjustable to allow for variations in the diameter of the wheel associated with the tachogenerator. As shown Fig. 1, a vehicle 18 carries and AC tachogenerator 10 (12) on each of two axles 16, 14. The AC output triggers a multi-vibrator 48, 72 respectively at the zero levels, the pulse width being adjustable. The AC signals are also fed through frequency to analog converters 24, 26 and the larger output opens a gate 54 or 56 to enable the higher velocity to be measured. Thus the pulse train output from multivibrator 48 or 72, whichever represents the higher velocity, is fed through its opened gate 54 or 56, and the trailing edge of each pulse triggers a generator 90 of precision length pulses. The combined pulse trains are fed to a chopper 100 to produce pulses of constant amplitude and duration which are averaged to measure the speed.

Patent ES-358244-A1 (ES)
Title: Traveling sign board
IPC: G09F11/26
Filed: 1968-09-17
Abstract: An endless indicia-bearing band 76 entrained about vertical drums 31, 66 is provided with detector means 140 adjacent the upper and lower edges of each drum which, if the band begins to slip off the drums, are engaged by the band and initiate a mechanism for tilting a drum (so restoring the band to its correct disposition), and subsequently restore the drum to its vertical orientation. Drum tilting.-As described, drums 31, 66 are mounted in yoke bearings Y, 61 respectively. As illustrated in Fig. 4a, tilting of a drum is achieved by a motor M rotating a screwthreaded shaft 46, causing movement of a screwfollower 47 and hence pivoting of yoke Y about a bolt 26. Tilting is controlled by microswitches 124 (Fig. 11), which energize a motor M and are actuated by detector rollers 140 which are displaced by tabs 76a, 76b if disalignment occurs. Extreme disalignment causes displacement of upper or lower safety switches 120 or 121 which cut off the band drive motor 60. Band tensioning.-The band is engaged by a friction sleeve G mounted on the drums, and is kept tense because idler drum 66 has its bearing yoke 61 secured to guide members 89 urged to slide to the right (in Fig. 3) by a spring 105, see also Fig. 9 (not shown). Alternatively, drum 66 may be replaced by three parallel rollers (141-143), two of them being tensioning jockey rollers mounted on spring-biased bell. crank levers (Fig. 15, not shown). Mounting.-Each of the runs of the band is viewed through a window in the framework, front-illuminated by tubes (L), Figs. 1, 2 (not shown). The framework comprises channelsection irons (C) clamped back-to-back about uprights (I) which support the sign, Fig. 13 (not shown).

Title: Anti-Pick Lock
IPC: E05B27/00
Filed: 1968-11-16
Abstract: Picking of a revolving-barrel, pin-tumbler look is prevented by the use of additional lateral tumblers in 'the barrel which are moved to the fastening or releasing position by movement of the main tumblers. As shown in Figs. 2, 3 and 4, the additional tumblers 17, 17a are normally held into engagement with holes 20, 20a by the main tumblers 13a, 13b. &C When key K is inserted to lift the main tumblers from the path of the side tumblers, inward movement of the side tumblers under the camming action of rounded surfaces 21 allows rotation of the barrel, Fig. 4. The tumbler drivers 14 have tapered noses 22 to enable them to act on the' tumblers when the barrel is slightly misaligned. When picking is attempted, the side tumblers accept the packing torque and no indication is given as to the position of the main tumblers 13. The side tumblers may be spring loaded at 24, as shown in Fig. 5.

The voltage drop across the feedback resistor 136, which is used for stabilizing the standing condition of the amplifier, being decoupled for A.C. by capacitor 144, is made equal to that across bias circuit resistor 142 so that the base potentials of transistors 72, 74 may be kept equal to provide symmetrical limiting. The H.T. supply to the amplifier is stabilized by means of resistor 118 and Zener diode 116, being fed to stage 22 via emitter-follower 120 and stages 38, 54 via emitter-follower 122 which also supplies the bias stabilizing circuit 134. The limiter 70 feeds into a discriminator comprising tuned circuits 84 and an arrangement 90, comprising diodes 160, 162 in conjunction with transistors 170, 172 which bias the diodes into conduction: an output is taken over volume control 94 and audio amplifier 100.
