Title: Method for the production and/or testing of welded helical seam pipe
IPC: B21C37/12
Filed: 1973-03-14
Abstract: A method of producing welded helical seam pipe, made from steel sheet or strip which is wound into pipe formation, is disclosed. Prior to the welding of the wound steel sheet, an optically scannable reference line is applied to the steel sheet which extends parallel to and adjacent one of the edges of the sheet. The welding is effected by applying a first welding seam with a first welding head located within the pipe interior and a second welding seam with a second welding head located outside the pipe. In accordance with the invention, the optically scannable reference line is applied to that face of the sheet which forms the inner surface of the welded pipe. The thus interiorly located reference line is optically scanned so as to obtain scanning information which, through operative connection to control means, controls the welding movements or operation of both the first and the second welding heads. The inventive method is particularly suitable in the production of pipe which is tack-welded prior to finish welding.

Patent ES-447505-A1 (ES)
Title: Method for feeding reactant gas to fuel cells in a stack and apparatus therefor
IPC: H01M8/00
Filed: 1976-04-30
Abstract: A flow scheme for feeding a reactant gas to the cells of a fuel cell stack wherein the cells are connected electrically in series. For example, the fuel gas is passed in parallel over a portion of each fuel electrode and thereupon into a mixing manifold which directs the exhausted gases in parallel over a different portion of each fuel electrode and thereupon into another manifold. This is continued, depending upon the stack configuration, with the exhausted gases passing back and forth in parallel over different portions of the fuel electrodes and exhausting into a manifold until the fuel gas has covered the entire fuel electrode of each cell in the stack. This reduces the harmful effect of a blockage within the reactant gas chamber of a cell and also reduces the harmful effect caused by a maldistribution of current in one of the cells in the stack.

Patent ES-467547-A1 (ES)
Title: Yarn winder
IPC: B65H54/28
Filed: 1978-03-03
Abstract: A yarn winder includes a package support roller and traversing mechanism which comprises slot-like guides on closely spaced contra-rotating driving members which may be either concentric or eccentric. A deflector arrangement at each end of the resultant field of traverse assists the transfer of the yarn from a guide on one driving member at one end of the field and then back to a guide on the first driving member at the other end of the field, each guide being followed in the direction of motion by a cam-like compensating surface, for temporarily increasing the length of the yarn path to take up slack which would otherwise be formed during transfer from one guide to another, and, in the case of concentric driving members, preceded in the direction of motion by a ramp-like lifting surface. Each of the deflector arrangements includes a control surface which is engaged by the yarn between the two yarn guides and is located in a gap defined on each side by a driving member and its associated yarn guide, the control surface at one end of the field of traverse being arranged to deflect the yarn in a direction away from the guides when the yarn is being transferred from an outer to an inner guide, and that at the opposite end of the field acting to depress the yarn toward the guides when the yarn is being transferred from an inner to an outer guide. Further control surfaces may be included for assisting the release of the yarn by a guide on one driving member and its retention by a guide on the other driving member to which it is being transferred.
Patent ES-468374-A1 (ES)
Title: Hysteresis compensated reed switch assembly for a position indicating system
IPC: H01H36/00
Filed: 1978-03-30
Abstract: The position of a control rod located within a nuclear reactor is sensed by a position indicating system utilizing low hysteresis reed switch assemblies. Each reed switch assembly includes a reed switch having an alternating magnetic flux field applied thereto through a coil surrounding the reed switch and energized by an alternating current power source. The amplitude of the alternating magnetic flux field is adjusted to be between a first flux level required to close the reed switch and a second flux level required to open the reed switch. The level of the alternating magnetic flux field is preset to be below the second flux level to maintain the switch in the open position until an external flux field is introduced to raise the total flux level above the first flux level to actuate the reed switch to close. The interaction of the alternating and external flux fields negates the hysteresis band of ordinary reed switches and provides a more sensitive and accurate position indicating circuit.

Patent ES-478854-A1 (ES)
Title: Apparatus for icing or freezing or frosting containers or hollow bodies, more particularly drinking-glasses
IPC: B01D5/00
Filed: 1979-03-21
Abstract: Apparatus for icing, freezing or frosting containers such as drinking glasses comprising a tank containing liquefied gas under pressure which is supplied through a valve and a coiled capillary conduit to a nozzle which sprays the liquefied gas into the interior of the drinking glass. A displaceable receiver plate is adapted for placement of the glass thereon and, in response to pressure applied to the glass, the receiver plate is displaced to open the valve which releases the liquefied gas from the tank into the coiled capillary conduit and, then, from the nozzle into the interior of the glass. The coil configuration of the capillary conduit provides resilience thereof and allows the same to undergo deformation as the receiver plate is displaced. The capillary conduit also serves to convey the liquefied gas along an elongated path to provide heat exchange with the ambient atmosphere, pressure reduction of the liquefied gas and a time lag so that, at discharge from the nozzle the liquefied gas is in an ideal liquid-gaseous state.
Patent ES-478903-A1 (ES)
Title: Valve deactivator for internal combustion engines
IPC: F01L13/08
Filed: 1979-03-23
Abstract: An internal combustion engine control system in which intake and exhaust valve deactivators are controlled in response to both engine throttle position and output speed in order to affect split engine operation. Voltages responsive to both throttle position and engine output speed are compared to generate a variable signal that controls the valve deactivators. Each deactivator includes a rotatable first cylindrical member axially fixed on an elongated engine support and also includes a second cylindrical member defining an enclosed cavity with the first member while positioned on the support between the engine and the first member. A helical spring of each deactivator encircles the cylindrical members thereof and has a first end axially fixed relative to the support and a second end that biases a rocker arm bearing toward the engine. Ports of the support and the first cylindrical member define inlet and exhaust passages to the cavity with the first cylindrical member in first and second rotational positions so as to allow the supply and exhaustion of pumped engine oil to the cavity in order to position the second cylindrical member and the bearing axially along the support so as to control valve operation. The deactivators associated with the intake and exhaust valves of selected cylinders are sequenced so that the intake valve ceases to operate prior to the cessation of the exhaust valve operation upon deactivation, and the exhaust valve begins to operate prior to the intake valve operation upon subsequent activation of the valves.
