Patent ES-345617-A1 (ES)
Title: The manufacture of spring units for mattresses and the like
IPC: B21F33/04
Filed: 1967-09-30
Abstract: A spring mattress is formed from a plurality of parallel bands 20 of helical springs, each band being formed from a single length of resilient wire and the bands being interconnected by transverse helical tie wires (21, 22). The bands 20 are fed through the mouths 47 of guide channels (44, Figs 5, 7) which extend to a linking station at which the helical, tie wires (21, 22) are fitted. Means are provided to advance the bands step-wise by an amount equal to the spacing of alternate coils in the band. The advancing means may include fingers (58, Fig. 7) depending from transverse arms 57 of a wheeled carriage 56 which is reciprocated longitudinally above the guide channels (44). The carriage drive comprises parallel links 49, 50 pivoted to a stand 42, interconnected by adjustable links 51, and driven by a pneumatic unit 52 acting through pivoted arms 53, 55. Claws (60, Figs 5, 6), carried by bars (59) extending between the forward links 49, engage the bands 20 simultaneously with the fingers (58) to advance the bands. Adjacent parts (25, Fig. 3) of the adjacent coils in each band 20 are engaged between lower and upper pairs of jaws 63, 64 at the linking station. Closure of the jaws 63, 64 produces alignment of the parts (25) to be joined transversely of the bands. At the linking station the helical wires are fed by rollers (72, 73, Fig. 6) in the manner of a screw through helical grooves (71) in the jaws to engage aligned parts (25) of the rows of bands 20. Means is provided for severing the helical wire after uniting the bands and for flattening the severed end of the wire into a closed loop. An alternative means for advancing the bands to the linking station comprises a pair of endless chains (91, 92, Fig. 11) which are driven at different speeds. The chains (91, 92) have teeth (94, 95) for respectively engaging alternate coils of the band (93). The teeth (94, 95) are respectively spaced slightly greater and slightly less than the spacing of alternate coils, the teeth (94) being associated with the faster moving chain (91).

Title: Methods of permanently elongating strip
IPC: B21D25/00
Filed: 1969-02-24
Abstract: A method of permanently elongating metal strip comprises applying tension to the strip and constraining the tensioned strip to at least one bend and at least one bend reversal such that yielding occurs on at least one side of the strip and such that on the first and all subsequent bend reversals the slope of that portion of the stress distribution curve for tensile and compressive stresses less than the tensile or compressive yield stress respectively reflects both the immediate previous bending strain and the existing bending strain reversal but is otherwise independent of bending strain history. Equations are given which show the relation between elongation strain and the applied tensile force for successive bends of specified radii on a strip of specified thickness and tensile yield strain the equations taking into account yielding at one or both sides of the strip at one or both of two successive bends. Examples of the application of these equations to a strip are given in which the values for elongation strain and tensile force were measured using the apparatus shown in Fig. 8 in which tension is applied to a strip 11 by an hydraulic cylinder 12 and measured by gauges 13 and 14 at each end of the strip. Bending strains are applied by rolls 17, 18 and 19 carried on a cart 20 running on a smooth track 21. A gauge length (50 inches) is marked on the strip, tension applied and the strip elongated by moving the cart with its rolls along the strip. The elongations obtained by measuring the distance between the gauge marks after stretching are in close agreement with those obtained from the equations given.

Title: Device for initiating an exothermic reaction
IPC: C22B60/04
Filed: 1969-05-07
Abstract: The exothermic calciothermic reduction of fluorides in the preparation of uranium or plutonium is initiated by dropping onto a mixture of uranium or plutonium fluoride with calcium in reactor 1 a refractory spherule 2 of calcium fluoride heated to the necessary temperature by electric furnace 8. Spherule 2 is supported on rod 4 by washer 15 which melts when spherule 2 reaches a certain temperature to allow spherule 2 to drop onto the mixture. This causes rod 4 to break the heating circuit of furnace 8. Washer 15 may be made of gold, silver or silver-gold alloy. In the embodiment of Fig. 2 (not shown) spherule 2 is of H cross section and is supported by a gold-palladium alloy wire which melts at the required temperature and breaks a relay circuit which disconnects the supply circuit for heating the furnace.
Patent ES-373919-A1 (ES)
Title: Device for feeding articles to paper wrapping machines
IPC: B65B57/14
Filed: 1969-11-26
Abstract: In a device for feeding chocolates 7 to the wrapping wheel 9 of a high speed paper wrapping machine 8 of the kind wherein endless conveyer belts 4, 5, are both driven by a common motor 30 which also drives the machine and so that the conveyer 5 travels faster than the conveyer 8, the chocolates 7 are transported between guide members 17, 17 to a fixed stop 6 where they are transferred, singly, by a pusher 8, to the wrapping wheel 9, the speed of the motor 30 being increased when the chocolates pile up behind the bar 6 to extend, rearwardly therefrom past a first 18, and up to, or beyond, a second chocolate, sensing mechanism 19. When there is no supply of chocolates to the low-speed conveyer 4 neither of the light beams 22, 23, Fig. 4, of the sensors 18, 19 which control respectively switches TL3, TL4, are interrupted so that neither of the switches TL2, TL1, which are controlled respectively by the switches TL3, TL4, are actuated to energize the motor 30 and move the conveyers 4, 5. When the chocolates build up behind the stop 6 sufficiently to interrupt the light beam 22 both pairs of contacts of the switch TL3 close so that power is supplied to the switch TL2 which, closes its contacts 1-3, 5-6 and opens contacts 4, 8 to supply energy to the motor 30 so that it runs at its normal speed. Build up of chocolates sufficient to break the light beam 23 of the sensor 19 actuates the switch TL4 which cuts off the supply to the switch TL2 which removes the supply from the motor 30 and closes the contacts 4, 8 to provide a circuit to the switch TL1 which closes contacts 1-3, 5-7 to supply alternative power to the motor 30 so that it rotates at its higher speed, and opens contacts 4, 8 in the circuit to the switch TL2. As the build-up behind the stop is reduced the motor 30 is changed to its normal speed as the light beam 23 ceases to be interrupted, the motor 30 switching off when the light beam 22 is also not broken. The circuits to the switches TL3-TL4 each includes an amplifier 26 or 27, a rectifier R 1 or R 2 , and a condenser C 1 or C 2 the time constant of which is chosen to ensure that the associated switch TL3 or TL4 ignores the passage of a single chocolate through the beam 22 or 23.

Patent ES-419522-A1 (ES)
Title: Video disc transmission line and stylus RF return systems
IPC: G11B3/02
Filed: 1973-10-10
Abstract: An information playback system, for recovering information recorded on a record medium, includes a pickup stylus having a conductive element establishing a capacitance with the record medium that varies with the recorded information, a conductive support housing, and a flexibly mounted conductive member supporting the pickup stylus and forming a transmission line with the surrounding support housing. The flexibly mounted conductive member has one end movably connected to the support housing and the second end mechanically coupled to the stylus to provide mechanical support therefor. An electrical connection is provided between the flexibly mounted conductive member and the conductive element of the stylus to establish a tuned circuit including the reactances of the transmission line and of the variable capacitance formed between the stylus and the record medium. A source of signal energy coupled to the tuned circuit energizes the tuned circuit such that signals modulated by the record information are developed in the tuned circuit. When the stylus is in playing position, capacitance between the support housing and the record medium is established with sufficient magnitude to provide a low impedance path for the modulated signals between the record medium and the support housing, completing the tuned circuit connections in a manner advantageous to pickup sensitivity.

Patent ES-428357-A1 (ES)
Title: Apparatus for adjusting the relative inclinations of pivotable members
IPC: E02F3/43
Filed: 1974-07-17
Abstract: This invention relates to apparatus for controlling the inclination of a pivotable member relative to a fixed structure, in particular the inclination of the jib of a crane. Control is effected by two jacks, each being connected by one end to the jib and by the other end to the body of the crane. The points of attachment of the jacks to the jib and the pivot axis of the jib define the vertices of two deformable triangles, one preferably being right-angled when the other has been flattened to a straight line. The lifting torque of a crane can thereby be substantially constant for all values of jib inclination.
Patent ES-440300-A1 (ES)
Title: Optical node correcting circuit
IPC: H04N5/272
Filed: 1975-08-16
Abstract: In a composite photography system of the type wherein a foreground camera photographs a normal dimensioned live actor while a background camera photographs scenery whose size is on a different scale in such a manner so that when the outputs from both cameras are superimposed the actor will appear to be performing in front of the scenery filmed by the background camera, it is necessary to slave the motion of the background camera to the motion of the foreground camera. With conventional type camera supports, the foreground camera's pivotal motions invariably take place about a pivotal axis which is spaced from the nodal point of the camera lens. In order to avoid distortion in the superimposed scenes as the background camera pivots to follow the pivotal motion of the foreground camera, compensation for the displacement of the foreground and background camera pivotal points from their nodal points must be provided to the background camera. Heretofore this has been done mechanically. This invention provides a method and means of electrical compensation instead of mechanical compensation for this displacement.
Patent ES-442302-A1 (ES)
Title: Method for reducing metal ores
IPC: C21B13/04
Filed: 1975-11-03
Abstract: An improvement in a method for the batchwise gaseous reduction of metal oxides, e.g., iron ore, to metals, e.g., sponge iron, in a multiple unit reactor system of the type in which separate bodies of metal-bearing material are simultaneously treated in one or more reduction reactors and cooling reactors. Reduction is effected with a gas composed largely of carbon monoxide and hydrogen generated by the catalytic conversion of methane and steam at an elevated temperature. Improved cooling is obtained by first feeding the freshly prepared gas to a reduction reactor rather than a cooling reactor, thereby minimizing formation of methane in the cooling reactor. In a modified embodiment, methane is fed to the cooling reactor and at least a portion of the effluent gas is recycled through the catalytic reformer.
