Patent ES-350096-A1 (ES)
Title: Continuous casting plant having adjustable strand guide means
IPC: B22D11/128
Filed: 1968-01-25
Abstract: Opposed pairs of guide rolls 1, 2 are adjustably spaced to accommodate the thickness of continuously cast strands 3, one roll of each pair being mounted on a fixed holder 5 and the other on a holder 51 movable by double-acting hydraulic rams 6 secured to the holder 5, the actual spacing being determined by spacers 12 inserted between the ends 11 of the ram cylinders 6 and brackets 9 on the ends of the piston-rods 7. The movable holder 51 is pivoted at 10 on the brackets 9. There may be a stack of the part-circular spacers 12 selectable to hook on to the piston-rod 7 (possibly in combinations). They are each mounted on one arm of a cranked lever whose other arm 121 is pivoted on a coupling on a shift rod 13 parallel to the strand 3 and longitudinally displaced by an hydraulic cylinder (15) at one end, to insert or retract a number of spacers 12 each associated with a ram piston-rod 7. Several pairs of holders 5, 51 bearing a number of roller pairs 1, 2 are arranged consecutively along the strand path The roll bearing members 4, 411 are spring- loaded perpendicularly to the strand, by dished annular springs, Fig. 4 (not shown). A set of strong springs (21) are unstressed during normal operation but yield to a fixed distance if there are major irregularities of the strand surface or foreign bodies in the guideway and a set of weaker springs (25) urges the members 4, 411 towards the strand to maintain roll contact for adequate cooling.
Patent ES-355111-A1 (ES)
Title: Carton forming machine
IPC: B31B17/52
Filed: 1968-06-18
Abstract: A carton formed from the blanks shown in Fig. 18, i.e. two end panels E and a base B and sides S hinged thereto, is formed in a die-andplunger mechanism in which pre-glued flaps F i and F o are folded against the end panels E. The plunger 18 is operated by fluid pressure and as it begins to descend thrust members 22 thereon engage the upper edges of the side panels E and carry them down into engagement with the base B of the horizontally arranged blank. As the blank descends flaps F are folded up against panels E by a centre portion 154 of the cavity of the die and flaps F o are only partially folded up by folding plates 152 that are set back further from the centre line of the die than the portion 154. A valve 238 (Fig. 4) is next actuated and piston and cylinder devices 228 extended thereby rotating shafts 218 to cause arms 222 to fold up sides S against the vertical edges of panels E. An arm on one shaft 218 trips a switch 246 to operate a valve 203 whereby actuators 196, 198 move the U-shaped plates 152 inwardly, to completely fold up flaps F o against panels E. Since flaps F o are not pressed against panels E until panels S are vertical the glue on flaps F o is not smeared or wiped off. The stroke of the die is controlled by stops 110, 112 on plunger 18 and as the die commences to lift rollers 80 (Fig. 10) move up in inclined slots 82 thereby retracting the cross-sectional area of the die and releasing the carton. The carton does not fall immediately but is held by inwardly extended folding plates 152 which retract as the die nears its upper position. The carton then falls on to an outfeed conveyer. The blank comprising panels B and S has its flaps pre-glued and trips a switch as it reaches its position under the die to initiate the forming cycle. The machine can be adjusted to accommodate blanks of different sizes.

Patent ES-429571-A1 (ES)
Title: Method and apparatus for recovering paper fibers from waste paper containing materials
IPC: D21C5/02
Filed: 1974-08-27
Abstract: Waste paper containing materials, e.g., commercial "waste paper" or municipal waste, are treated for recovery of reusable paper therefrom by slushing in a pulper followed by screening of the entire output extracted from the pulper, with or without an intermediate centrifugal cleaning operation, in a screen having fine perforations sized to accept only substantially fully defibered paper. The reject flow from this screen is maintained at an adequately high rate, e.g., 20-80% to assure freedom from blocking of the screen perforations. A deflaker is connected to receive this reject flow, and the output of the deflaker is separated by a tailing screen into accepts which are recycled to the primary screen and rejects which are eliminated from the system. Major advantages of this method and system include the use of only one piece of apparatus for each of the essential operations of pulping, screening and deflaking, the elimination of low specific gravity reject from the system at a single station, and distribution of power requirements in such manner that the ratio of pulping power to deflaking power is 1.5 or less.
Patent ES-432035-A1 (ES)
Title: Multi-step chemical and radiation process
IPC: C01B3/06
Filed: 1974-11-18
Abstract: A process which utilizes radiation energy, preferably that obtained from a fusion reaction and which includes selecting starting chemical materials having at least two molecules such as calcium bromide and water which contain as a part thereof a desired product H2, a by-product O2 and which chemically form an active material HBr that may be dissociated by radiation. A two step process permits the radiolytically dissociated Br to react with residual molecules to form and recycle the starting material CaBr2. A combination of thermochemical and radiolytic reactions such as available in nuclear reactions therefore produces a greater yield of a desired end product such as hydrogen, also producing a by-product such as oxygen from a low cost expendable source material such as water, and reforms the starting material. Also the process provides for convenient separation of the desired end products.

Patent ES-456300-A1 (ES)
Title: Method of and apparatus for separating gas from liquid during treatment of waste liquid
IPC: C02F3/22
Filed: 1977-02-25
Abstract: One of the stages involves the sepn. of gas from the waste water. The extn. of a large proportion of both gas bubblesand dissolved gas is enhanced by reducing the press. on the surface if the waste water to well below atmos., i.e., to less than 0.4 (pref. 0.3-0.1) bar. In the case of a biological purificn. process comprising oxygenation, e.g. with injected air, followed by a sedimentation stage, the gas removal stage is introduced between oxygenation and sedimentation. A further stage of flotation sepn. may be included between oxygenation and gas removal. Used in the treatment of sewage and industrial effluents, the method removes a high proportion of dissolved gas as well as gas bubbles which, alone, could be satisfactorily eliminated by mechanical agitation. The resulting, more efficient removal of gas leads to better clarification by subsequent sedimentation.

Patent ES-460160-A1 (ES)
Title: Data bus arrangement for Josephson tunneling device logic interconnections
IPC: H04B3/00
Filed: 1977-06-28
Abstract: A data bus is a common interconnection which serves as a two-way data link between inputs and outputs of several logic blocks in a time shared manner. A data bus arrangement is disclosed which can be utilized to interconnect a plurality of ports with each other and which utilize Josephson junction devices. Each of a plurality of ports represents the output from a computer or other logic circuit and these outputs represent inputs on control lines associated with each Josephson device which switch it. Each Josephson device is separately energized from its own current source and, upon switching, diverts current down a transmission line which has an impedance, Zo. In a single wire-over ground plane embodiment, all of the transmission lines are connected to a single node in a star arrangement. A terminating resistor which terminates each of the lines in a value of resistance equal to Zo is disposed in series in the transmission line and is intended to absorb signals coming from any port so there is no reflection of incoming signals back along the transmission line. From the node at which all the transmission lines are connected, a signal generated at one port, for example, passes in parallel to each of the other ports. There, depending on whether or not a sensing Josephson junction which is associated with each transmission line is enabled, the signal is sensed at a selected sensing junction. The present approach utilizes the fact that, when an input junction is in the unactuated state, it represents a short circuit presenting no internal impedance to the incoming current which can then be absorbed in a resistance which, in spite of the presence of the switchable device, remains as a termination equal in resistance to the characteristic impedance of the transmission line. A double wire over ground plane or a wire above and below ground plane embodiment is also shown, wherein the two wires or transmission lines associated with each input port are connected to a pair of nodes. Each line has the same characteristic impedance and each is terminated by a resistance equal to the characteristic impedance. In this arrangement, the resulting signal strength available for sensing can be two times the strength of the single wire embodiment, due to a reversal of the transmission line in the neighborhood of a sense gate.
