Patent ES-338418-A1 (ES)
Title: Recovery of elemental sulphur from sulphide ores
IPC: C01B17/06
Filed: 1967-03-23
Abstract: Elemental sulphur is recovered from pyritic bearing ores by stagewise fluidized bed treatment in which the ore is partially decomposed in a first fluidized bed treatment zone to volatilize the labile sulphur atom in the ore and then the partially decomposed ore is fluidized bed roasted in a subsequent zone to produce hot SO 2 -containing gases and an iron oxide calcine characterized by feeding to the first zone hydrocarbon reducing agent preferably directly into the body of the ore undergoing treatment, and the hot SO 2 -containing gases generated in the subsequent roasting zone whereby owing to the combustion of the hydrocarbon in the first zone, reducing agents are produced effective to reduce the SO 2 to elemental sulphur. The reducing agent may be a finely divided carbonaceous material, a liquid hydrocarbon fuel or natural gas. The temperature of the solids in the volatilizing zone is maintained in the range between 600 and 900 C., and in the roasting zone between 800 and 1000 C. The two-stage process represented in Fig. 1 contains a volatilizing zone "V" in the upper shell 10 and a roasting zone "R" in the lower shell 12. Each shell has a fluidized bed of the material being treated, namely 30 and 32 in shells 10 and 12, respectively, and is supported on a gaspermeable plate 22, provided with a plurality of orifices 24. The solids and fluidizing gases move generally countercurrently, the former moving downwardly through "V" and "R" via conduit 64, and the latter moving upwardly through "R" and "V" via inlet 38. Ore is introduced into bed 30 through conduit 62, and reducing agent is introduced through conduit 68. The hot SO 2 -containing gases from "R" are introduced into "V" at a velocity sufficient to fluidize bed 30, and contribute a portion of the heat necessary to maintain the temperature of the solids so that the labile sulphur in the ore is volatilized. Entrained fines in the SO 2 gas from "R" are removed in cyclone 34, and entrained fines in the exhaust gas from "V" are removed in cyclone 54. Bed 32, comprising the partially desulphurized ore, is fluidized by air and preheated air introduced respectively through valved conduits 46 and 72. Three and four stage fluidized bed reactors are also described.

Title: Method of making animated figure toys having embedded connector means and a thickened area
IPC: A63H9/00
Filed: 1967-06-05
Abstract: An animated figure toy having a predetermined shape is made by forming a first layer of heated, gelled plastic material on the inner surface of a mould, forming a second layer of heated gelled plastic material on a predetermined portion of said first layer on said inner mould surface, and curing said first and second layers to form a hardened unitary hollow article within said mould having a thickened portion corresponding to said second layer, connecting an animating means to said material by pressing an animator connector means into engagement with said material at a predetermined position on said first layer, softening said material under said connector means while maintaining pressure for embedding a portion of said connector means in said material, re-solidifying said softened material about the embedded portion of said connector means, and connecting animator means to said connector means for moving said portion of said toy to animate it upon actuation of said animator means. In an embodiment a mould 14 is filled with liquid plastic material 16 (Fig. 1) and heated in bath 18 so that a layer of said material forms inside the mould, and then the mould is orientated in such a way, and filled to such an extent with the same or a different liquid plastic 22 that on heating in a bath 24 (Fig. 3) a second layer is formed over a predetermined area of the first layer, in this case to give a doll's head as shown in Fig. 4. A metal animator connector means of the shape shown in Fig. 7 may be embedded in a lip 58 of the doll's head by heating the connector by electrical resistance heating and pressing it into the plastic. The insertion of such a connector into a lip may be performed using the apparatus described, and the insertion of a connector into each lip of a doll's head may be used in conjunction with animator means 72 to give a "talking doll" effect.

Title: Warning lamp circuits for battery charging systems
IPC: H02J7/14
Filed: 1967-05-26
Abstract: The charging of a battery 10 by the alternator/ rectifier unit 9 of a vehicle is indicated by the extinguishing of a lamp 11 which is in series with the ignition switch 8 and a resistor 12 of positive temperature coefficient across the battery 10, the junction of members 11, 12 being connected to the phase point of the alternator through a diode 13. When the battery is not being charged the value of resistor 12 is such as to cause illumination of the lamp 11, but when the alternator is charging the battery the current through members 12, 13 is sufficient to heat the resistor 12, raise its resistance and so extinguish the lamp. In a modification, Fig. 2 (not shown), the diode 13 is omitted and resistor 12 is heated indirectly by a resistor (14) connected between the alternator phase point and earth.
Patent ES-344102-A1 (ES)
Title: Look-ahead control circuitry
IPC: G06F3/00
Filed: 1967-08-14
Abstract: In a system in which a command signal, Fig. 2, at the beginning of one cycle causes some operation, e.g. punching or printing, to occur at the beginning of the next cycle, each command signal is compared with the previous command signal and only if they differ is the state of the device which effects the operation changed. The system described is for controlling a punch 25, Fig. 1. To effect punching a magnet 18 has to be de-energized at time G in a cycle of operation determined by a cam-shaft 22, to allow a lever 20 to move away from the magnet under the action of a spring 21 and interpose a member 23 between a striker 24 and the punch 25. Punching then occurs at the beginning of the next cycle after which the cam 22 forces the lever 20 back to its position against the magnet (as shown) and withdraws the interposed member 23. If the magnet 18 is energized at this time then the lever 20 is held against the magnet and no punching occurs in the next cycle. If the magnet is not energized then lever 20 continues to follow cam 20 and punching does occur in the next cycle. Incoming punch command data-Fig. 2 shows the sequence "11001"- occurs on a line 12 and each bit sets a latch 15 at C time. Thus the "1" bit in the first cycle sets latch 15 at C time. At G time, if a latch 16 which controls magnet 18 is not reset, as in the first cycle, then the "1" bit stored in latch 15 causes it to be reset via a gate 31. This deenergizes magnet 18 and causes punching to occur at the beginning of the second cycle. At C time in the second cycle the incoming "1" bit is again stored in latch 15, this having been reset at A time. At E time in the second cycle an attempt is made via a gate 32 to set latch 16 and thus re-energize magnet 18. However, since at this time latch 15 is set, gate 32 is not open, and therefore latch 16 remains reset and punching occurs at the beginning of the third cycle. The incoming data bit for the third cycle is a "0", therefore latch 15 is not set and at E time latch 16 is set. This re-energizes the magnet 18 and no punching occurs at the beginning of the fourth cycle. However, to ensure that the lever 20 does not bounce off magnet 18 the current through it is momentarily increased during F and G times by a monostable circuit 34 which is turned on, in these circumstances via a gate 33, to remain on for longer than F and G times, and which allows a pulse from two S.C.R.'s 40, 41, to be superimposed upon the normal magnet current. The necessity for this feature depends upon the precise characteristics of the punching mechanism and in certain circumstances it may not be needed. This leads to simpler circuitry (Figs. 3 and 4, not shown).

Filed: 1968-03-16
Abstract: A transformer tap changer comprises two rings S 1 , S 2 of fixed contacts which are respectively connected to the odd taps 1, 3, 5, 7 and the even taps 2, 4, 6, 8 of transformer 10 and surround a control shaft 21 carrying movable contacts 19, 20 which are alternately connected to a load 9 by an on-load change-over switching device I, II, the spacing and arrangement of the two sets of fixed contacts S 1 , S 2 and movable contacts 19, 20 being such that in each stable position of the tap changer one of the movable contacts, e.g. 19 engages the centre of one of the co-operating contacts, e.g. 13 and the other movable contact, e.g. 20 is between and spaced from two contacts, e.g. 12, 14 of its co-operating fixed contacts. Starting from the position shown switch I, which comprises thyristors in antiparallel, is closed but the load is supplied through a parallel circuit completed through movable contact 24 and one of the contacts 22. As the shaft 21 rotates clockwise contact 20 engages fixed contact 14 while contacts 13 and 19 are still engaged, but movable contact 24 and its co-operating fixed contact 22, and a further movable contact 25 and its co-operating fixed contact 23, are opened thereby ensuring that switch I carries al] the current to the load 9. In this continued movement from one tap to another the switch I is then opened before switch II is closed. In this position the load is connected to tap 4 and the current passes to the load through contacts 23, 25 of switch C/cII. The switches I + II are thyristors which may be rendered conducting or non-conducting by gate cathode circuits opened and closed by sealed magnetic contact devices actuated by permanent magnets carried by shaft 21. As shown, however, the thyristor switches I, II are controlled by photo-electric devices 26, 28, and 27, 29 respectively. Each device comprises a light source, e.g. 28 and a photo diode 28, a slotted disc 30 keyed to shaft controlling the illumination of the diode. A servomechanism (Fig. 4, not shown) positions the shaft 21 in accordance with an adjustable reference member, Application No. 535/68, Serial No. 1,204,612 is referred to.
