Patent ES-338171-A1 (ES)
Title: Concentric tube odor eliminator
IPC: B01D53/34
Filed: 1967-03-17
Abstract: Noxious vapours to be burnt are fed in at 12 to pass through concentric passageways 17 to a burner 24 in a combustion chamber 20. The burnt gases pass out through passages 19 concentric with the inlet passages 17 to an outlet 14, Fig. 4. A cylindrical baffle 32 in the combustion chamber 20 increases the residence time of the gases. The inlets 12 extend over only a small part of the area of the top of the heat exchanger passages 17, 19, the remaining area forming a free outlet 14. The burner may be replaced by an electric element, and catalytic material may be arranged in the combustion chamber 20. The flow of gases may be from a central inlet to the annular passages, the burnt gases flowing up the central baffle. The walls of the concentric passageways may be corrugated to provide an extended contact surface.

Title: Composite container and method of handling fluent materials
IPC: B65D88/62
Filed: 1967-11-21
Abstract: A container for non-gaseous fluent materials includes a flexible lining and at least two connections for inflating the lining prior to filling while permitting escape of air from the lining. A further connection or opening permits escape of air from between the lining and outer wall. The connections may include an inlet tube perforated along its length within the container. In one form, Figs. 1, 3, the neck of the lining 28 is secured about a perforated tube 24 at the lower end of which is a lining positioning plate 25. The tube is secured to a head plate 20 which accommodates a valve 38 for relieving or permitting entry of air between the lining and container 15 and a pressure relief valve 39. A head at the upper end of the tube 24 houses a dip tube 33, a closable connection 32, a pressure relief valve 36 and a valved connection 37. To distend the lining, air or gas is forced in via the valve 37 and tube 24 or alternatively through the tube 33. The material being packaged is then passed in through the tube 33. Displaced air or gas exits through the tube 24 and valve 37. To discharge the material, the space between the lining and container may be pressurized, forcing material out through the tube 33. In another method, the space is merely connected to air via the valve 38 and the contents pumped out through the dip tube. Flowable solid material can be fluidized by a tube, Fig. 4 (not shown) passed through the connection 32 with its gas discharge exit angled to direct the flow out of one of the bottom openings 27 of the tube 24. A discharge pump can be mounted within the container at the bottom of the dip tube. The connection 32 permits a stirrer, heater, cooler &c. to be lowered into the contents. The contents can be withdrawn and returned to the container after treatment by a circulator and appropriate connections, Fig. 5 (not shown). In another form, Fig. 8 (not shown), a screwin plug for the container has the liner mouth secured to its inner end and houses only a dip tube with a plate similar to the plate 25 and a single aperture at its lower end. It has also a through bore serving the purposes ofthe tube 24. Another embodiment, Figs. 12, 15, includes a bottom discharge door 317a and a lining with a bottom opening. A cap 320 having the necessary connections 359, 360 may be replaced after filling by a plain closure, Fig. 14 (not shown). In a further embodiment, Figs. 11, 17 (not shown), the container is filled and discharged from a position adjacent the bottom and a flexible tube extending up to the top of the space within the lining permits gas entry and exit.

Patent ES-356825-A1 (ES)
Title: Stranding machine
IPC: D07B3/04
Filed: 1968-08-02
Abstract: A stranding machine, Fig. 1, having a plurality of spaced apart spools 11 to 15 mounted for rotation in cradles 16 floating in spaced apart bearing structures 17, has the wires from the spools arranged to follow a sinusoidal path evenly disposed about the longitudinal axis of the machine, the wires between the bearing structure 17 being supported by rotatable curved support members 25. The support members 25 may comprise groups of wires 25a, Fig. 4, supported by spaced apart clamp members 31, each clamp member 31 comprising an outer portion 31a provided with recesses for locating the wires 25a and an inner portion 31b having recesses 31c forming guides for the wires from the spools 10 to 15. The clamp members 31 prevent the wires from the spools 10-15 from falling down when the machine is stationary. In Fig. 2 (not shown) the groups of wires 25a pass continuously in an unbroken manner throughout the length of the machine. In Fig. 8 (not shown) there is shown two alternative embodiments in each of which the wires 25a (61) are in individual lengths within the support members 25. In Fig. 13 (not shown) the support member 25 is also wound about the axis of the machine and is in the form of a curved sheet or strip of metal. This strip may have eyes on its inner or outer surface to support the wires to be stranded, Fig. 9 (not shown). Stop motion responsive to wire breakage Each wire spool is supported on pintles 84, Fig. 12. Mounted on each pintle 84 through a ball and helical groove connection 87 is a flywheel 88. Under normal running conditions the flywheels 88 are adjacent the spool but if the wire from the spool breaks a friction drag on the spool causes the spool to slow down and this permits the kinetic energy of the flywheels 88 to rotate them away from the spool, this movement of the flywheels away from the spool causing a flange 99 on the flywheels to move away from between an air-flow path between two opposed orifices 100, 102 the resultant increase of pressure in duct 102 being used as a signal to operate brake means to stop the machine. Stop motion for excessive rocking of cradles Each cradle carries a pivotally mounted weight (108) Fig. 10 (not shown) that under normal conditions is suspended between opposed orifices (109, 111). If the cradle rocks excessively, due say to a faulty bearing, the weight (108) swings to settings permitting air to flow between said orifices, the resulting rise in pressure in one of the orifices being used as a signal to operate means stopping the machine. Each spool is acted on by a belt brake to tension the wire being pulled therefrom.
Patent ES-357614-A1 (ES)
Title: Differentiators
IPC: H04L25/02
Filed: 1968-08-28
Abstract: A circuit responsive to the change of an input signal 10 from either of its two states to the other includes a comparator 12 which receives the input signal and produces an output at 17 only when this input is different from the output 13 of a bi-stable 14, the bi-stable changing state only when the comparator output 17 coincides with a clock pulse from a clock 16. The input signal may be a variable signal (S, Fig. 4a, not shown), the two states of which are regarded as being above a first limit (" 1 ") and belowthe same or a second limit (" 0 "). The signal, alternatively, may be digital, or may have amplitude states representing frequency limits of a variable frequency signal. An input circuit to the comparator may be a dead-band amplifier, or a Schmitt trigger. When the input signal (S) falls below the " 0 " level, the comparator 12 inputs are different and it produces an output at 17 (Fig. 4c, not shown). Coincidence of the next clock pulse (C2) with the comparator output is sensed by an AND gate 15 which operates the bi-stable 14, and consequently both inputs to comparator 12 become the same again, and its output ceases. The cycle repeats each time signal S passes into one or other state. A further bi-stable (18, Fig. 2, not shown) between the input 10 and the comparator 12 is also controlled by clock pulses and ensures that the start of each comparator output pulse (Fig. 4e, not shown) at 17 is synchronized with a clock pulse, the output pulse length depending upon circuit values. In a different embodiment (Fig. 3, not shown), a first clock-controlled J-K bi-stable (21) directly controls a second clock-controlled J-K bi-stable (22) corresponding to the bi-stable 14 of Fig. 1, the comparator being in the form of two AND gates (23, 24), the two inputs of one gate being connected to the direct output of one bistable and the inverse output of the other, and the two inputs of the other gate being connected to the remaining bi-stable outputs, so that neither gate normally conducts. The AND gates respectively respond to opposite input signal states a change of state of input changes over the first J-K bistable to provide two " l's " to one of the AND gates and hence an output (e.g. at 26) and after a delay determined by circuit values the second J-K bistable changes over and the output disappears.
Patent ES-358604-A1 (ES)
Title: Automatic gain control circuit
IPC: H03G3/30
Filed: 1968-09-27
Abstract: In a signal receiver the A.G.C. controlled current in one stage is used to control the gain of a later stage in reverse sense aboveapredetermined signal level, so that the gain of the later stage then remains constant. As applied to a television receiver an A.G.C. circuit of the gated type derives a delayed control potential from sync. signals in circuit 50 which is applied over line 52 to the base of I.F. amplifier 58, via resistor 54 the arrangement is such that gain is reduced by increasing the collector current. The change in potential across emitter circuit resistor 60 so caused is applied via resistor 64 to the base of preceding I.F. amplifier 68 so that its gain is likewise reduced. The gain control potential on line 52 is also applied over a further delay circuit 74 and resistor 76 to reduce the gain of R.F. amplifier 80 by increase of collector current. The gain is initially reduced in the I.F. stages when the gain in the R.F. stage 80 begins to be reduced the increase in voltage drop across resistor 82 in the collector circuit is applied over resistor 100 to the base of the I.F. stage 58. The gain control potential derived from line 52 is thereby opposed, so that the current in transistor 58 remains constant, thereby maintaining the gain of this stage and of transistor 68 constant. When the R.F. stage 80 becomes biased back, no further change in the potential derived via resistor 100 occurs, and the gain of the I.F. stages reduces once again.

Title: Means for agricultural seeding
IPC: A01C7/20
Filed: 1969-07-19
Abstract: An agricultural sowing machine comprises a frame 13 for mounting arm assemblies 36 which carry soil cutting discs 42, these being resilient means 50, 55 urging the arm assemblies away from the frame, and a resilient connection 29 between the frame and a member 11 connected to the frame, the adjustment of which connection alters the loading applied to the discs 42. Each arm assembly comprises pairs of arm 37 and 38. Each arm 38 carries a depth control roller 41 whose vertical position may be varied, and a pair of inclined soil cutting discs 42. A rod 52 pivotally connected to each arm assembly 36 passes through a member 54 and is surrounded by compression springs 55 and 56 whose loading is controlled by an abutment member 57. If a depth control roller 41 or cutting disc 42 encounters an obstruction, the corresponding arm assembly 36 will lift due to the yield of spring 55. A rod 24 engages members 11 and 13 at trunnion blocks 26 and 20, and is surrounded by compression springs 29 and 30, and rotation of handle 32 alters the effective length of the rod between trunnion blocks 20 and 26, thus ensuring that there is adequate weight on the discs 42 to provide adequate soil penetration, whilst maintaining adequate weight on ground compacting rollers 44. Seed is delivered through a tube (90), Fig. 4 (not shown), located adjacent to each disc 42 from a box 70 whose delivery is controlled by a seed metering device driven by the action of the spider wheel 74. A skim (94), Fig. 3 (not shown), prevents vegetation from gaining access to and blocking the seed tube.

Title: Circuit breaker with improved latch reset
IPC: H01H71/50
Filed: 1969-12-04
Abstract: A circuit-breaker 3 cannot be reset after tripping if the contacts have failed to open, e.g. because of welding. In normal resetting, a radius 171 at the knee 61 of the toggle 53, 55 engages a surface on a latch member 71 to pivot it against a spring 93 to move a trip bar 73 to a latching position in which a surface 89 on the trip bar 73 engages a surface 91 on the latch member 71, member 71 including a roller 77 under which engages the hook-shaped end 95 of a releasable trip member 57. If the contacts 19, 21 are welded, the toggle 53, 55 is restrained from moving sufficiently to actuate the latch member 71 to its latching position and, if the handle 49 is released after a resetting attempt, the tension spring 67 automatically moves the handle back to the "on" position, thus indicating that the breaker has not reset and the contacts are closed.

Title: Alkylation of aromatic amines
IPC: C07C209/68
Filed: 1974-05-31
Abstract: Aromatic amines which are substituted on the ring by one or more optionally substituted aliphatic or cycloaliphatic hydrocarbon radicals are prepared by reacting an aromatic amine having at least one unsubstituted ortho-position on the ring and at least one hydrogen atom bonded to the amine nitrogen atom with one or more aliphatic or cycloaliphatic hydrocarbons which contain at least one olefinic double bond and which may contain substituents which do not affect the reaction. This reaction is carried out at a temperature from 200 to 500 DEG C in the presence of a catalyst formed by reaction of aluminium or an alkylaluminium compound with an aromatic amine. The essential feature of the process is that hydrogen halide is added to the reaction mixture in such amounts that up to two halogen atoms are obtained per aluminium atom in the mixture. The amines prepared are valuable intermediates for the preparation of dyes, and are used for the synthesis of various selective herbicides.

Patent ES-457156-A1 (ES)
Title: Friction clutch with integral adjuster
IPC: F16D13/46
Filed: 1977-03-24
Abstract: A friction clutch is of the type comprising a clutch cover for attachment to a flywheel, a pressure plate, a main spring assembly arranged to act between the cover and the pressure plate to provide a clamp load to urge the pressure plate towards the flywheel and thereby grip a driven plate between the friction surfaces of the pressure plate and flywheel, and a release mechanism for relieving the clamp load. The pressure plate is formed in two relatively adjustable components which can compensate for variations due to wear in the thickness of the driven plate and thereby maintain a constant clamping condition of the main spring. An adjuster mechanism incorporates relatively adjustable inter-engaging members of the two pressure plate components which maintain a constant inter-engaged state during release and re-engagement of the clutch while the clutch remains in the desired state of adjustement. A control member responsive to movement between the released and engaged conditions of the clutch is operative to effect an incremental adjustment of the inter-engaging members when said movement exceeds a predetermined distance.
