Patent ES-422777-A1 (ES)
Title: Magnetic guide roller for conveyor belts
IPC: B65G39/08
Filed: 1974-01-30
Abstract: The guide roller includes a stack of concentric first, second, third, fourth and fifth disk-shaped sections. The first section is sandwiched between the second and third sections and has the same diameter as the second and third sections, to form therewith the hub of the guide roller. The first section is of magnetically conductive material, not permanently magnetized to any appreciable degree. The second and third sections are permanently magnetized in axial direction, with the facing axial pole faces of the second and third sections being of like polarity. The fourth and fifth sections have diameters greater than the diameter of the first, second and third sections, so as to form radially outwardly projecting guide flanges for preventing lateral shifting of a belt travelling around the hub formed by the first, second and third sections. The fourth and fifth sections completely cover the outer axial pole faces of the respective adjoining ones of the second and third sections. The fourth and fifth sections are of magnetically conductive material not permanently magnetized to any appreciable extent. The characteristic feature of the structure is that the portions of the magnetic flux loops extending outside the material of the first through fifth sections are confined almost exclusively to the annular space intermediate the radially outwardly projecting portions of the fourth and fifth sections. As a result, a strong magnetic attractive force will be exerted upon attractable material in this region, but the magnetic flux, being confined to the just-mentioned annular space, will not interfere with the magnetic action of any other magnetic or magnetizable structure in the conveyor belt arrangement.

The piston has axially spaced first and second sealing lips adapted to sealingly engage with the inner surface of the tubular container, and the first sealing lip is deflectable to permit passage of the lighter phase past this sealing lip on movement of the cup-shaped piston downwardly, through the lighter phase, while preventing the heavier phase from such passage.
Patent ES-435317-A1 (ES)
Title: Method and apparatus for texturing continuous filament yarn
IPC: D02G1/12
Filed: 1975-03-05
Abstract: A method and apparatus for texturing continuous filament yarn wherein the yarn is fed at a controlled rate and under controlled tension into a confined crimping zone against a mass of crimped yarn therein causing the yarn to collapse longitudinally forming crimps which become part of such mass. Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps. The crimped yarn mass is then fed at a controlled rate from the crimping zone into a setting zone. Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps. The pressure applied to the yarn mass in the setting zone is substantially only sufficient to keep the crimps closed during the final setting thereof. The crimped yarn mass is then fed from the setting zone into a cooling zone. The yarn mass is cooled in the cooling zone to a temperature below that at which the yarn undergoes any molecular structural alteration in the absence of the application of a substantial force thereto. Finally, the yarn is withdrawn at a controlled rate from the cooling zone in continuous filament form.

Title: De-clutch mechanism for valve operator
IPC: F16D15/00
Filed: 1976-02-26
Abstract: A de-clutch mechanism is actuated, when the power is off, by manual actuation of a de-clutch lever shaft. When thus actuated, the de-clutch mechanism couples a rotatable driven sleeve to a handwheel drive and decouples the sleeve from the power drive. When the power is activated, the de-clutch mechanism automatically disconnects the handwheel drive. A typical application of the de-clutch mechanism is in valve operators.

Patent ES-456002-A1 (ES)
Title: Automotive brake fluid low-level warning sensor
IPC: B60T17/22
Filed: 1977-02-17
Abstract: In a hydraulic brake system, a housing includes a brake master cylinder and a reservoir formed therein for containing a supply of brake fluid. A sensor piston in contact with the pressure in the brake master cylinder is connected to an indicator piston. The indicator piston is coaxial with a blind cylindrical indicator bore. The blind bore and indicator piston are in communication with the reservoir at a level below which the brake fluid should not be allowed to recede. When the brake is operated, brake master cylinder pressure urges the sensor piston outward. The connected indicator piston is urged toward the blind bore. If the reservoir contains fluid, the blind bore is filled with the fluid. Fluid lock of the indicator piston therefore occurs before any appreciable indicator piston motion into the blind indicator bore. On the other hand, if the reservoir, and the communicating indicator bore, are empty, the indicator piston is enabled to enter the indicator bore by compressing air therein. Motion of the indicator piston into the indicator bore actuates an electrical switch which energizes a warning indicator. Once fully actuated, the electrical switch is mechanically latched in the on position to provide a continued warning indication until it is manually reset after replenishing the brake fluid. In one embodiment of the invention, intermediate brake fluid levels cause the generation of momentary warning signals.

Patent ES-456936-A1 (ES)
Title: Method for etching thin foils by electrochemical machining to produce electrical resistance elements
IPC: H01C17/00
Filed: 1977-03-17
Abstract: A process for etching a thin film or foil of an electrically conductive resistive material, preferably an alloy predominantly comprising nickel and chromium, by electrolytic etching under conditions of electrochemical machining above Jacquet's plateau on the I.V. characteristic curve. The process is particularly suitable for manufacturing a planar electrical resistor having a high stability, a low temperature coefficient, and a high ohmic value despite the relatively low resistivity of the film or foil. The anode surface polarization is maintained substantially constant over the surface of the foil or film by removing the by-products of the etching process, i.e., gases, viscous layers and other impurities, by mechanical effects such as an electrolytic flow or mechanical vibration, or both together. These mechanical effects are carefully balanced against the applied potential values such that the rate of formation of the layers and gases at the anode is equal to their rate of removal. Moreover, the anode electrical resistance is kept at a negligible value independent of the progress of the attack, by securing the film or foil to a thick layer of a conductor such as copper, whereby the evolution of potential drop across the foil, due to the electrical current flow, is kept at a negligibly small level. Under these conditions, a quasi-uniform etching is obtained all over the foil or film surface. The operating parameters of the process are also described as well as the advantages of the resistor produced according to the process of the invention.
Patent ES-457153-A1 (ES)
Title: Remote control system preventing information loss - uses control centre to acknowledge correct receipt of outstation data
IPC: H04L1/16
Filed: 1977-03-24
Abstract: The information loss in a remote control system is prevented by transmission of the information from the outstations to the control centre as continuous addressed block-blocks. The control centre then acknowledges the correct receipt of information blocks by transmitting their addresses back to the outstanding asynchronously. The information blocks, for which no address is transmitted back as acknowledgment of correct receipt, are repeated once or several times by the outstation concerned. The acknowledgement telegram is transmitted back at an arbitrarily chosen later thime and is asynchronous relative to the information blocks. High priority acknowledgement is provided for high priority instructions.

Title: Automatic control apparatus for oscillating-type grain sorting machine
IPC: B07B13/11
Filed: 1979-04-23
Abstract: An automatic control apparatus for an oscillating-type grain sorting machine in which a grain sorting plate with a rugged surface oscillates in a direction of an angle of elevation for shaking up grains so that mixed grains are separated toward one side at front and/or rear of the sorting plate and flowed out sideways.
