Patent ES-479973-A1 (ES)
Title: Tube bundle heat exchanger
IPC: F28D7/06
Filed: 1979-04-26
Abstract: A tube bundle heat exchanger with baffles is disclosed wherein a tube bundle is housed within an inner casing which is acted upon from both the inside and the outside by a heating medium. The inner casing is not stressed by pressure caused by the heating medium since the medium flows both within and without the casing. The part of the circumference of each baffle which is in contact with the inner casing is tightly connected to the inner casing in order to prevent leak flows. Adjacent heat exchanger tubes of the tube bundle are separated from one another by a zigzag-shaped dividing wall. The dividing wall forms space-economical rerouting channels with the baffles. The tubes of the tube bundle are located parallel to the longitudinal axis of the heat exchanger, and therefore longitudinal in the longitudinal rerouting channels. The heating medium which flows through the rerouting channels flows across the tubes producing favorable heat transfer conditions.

Patent ES-480567-A1 (ES)
Title: Stencil duplicator
IPC: B41L13/08
Filed: 1979-05-14
Abstract: An automatic control mechanism for the thickness of an ink layer on a duplicator cylinder employs a sensing roller mounted for movement along a path which extends both peripherally and radially of the cylinder where the ink is to be measured and thus the drag on the ink pulls the cylinder to an equilibrium position where it just maintains sufficient contact with the layer of ink to be subject to that drag whereas any further movement will move it radially away from the ink layer to lose contact. The pivoting support for the sensing roller engages a switch when an extreme position is attained and this provides an "enough ink" signal. An adjustable biasing mechanism enables the position of the sensing roller to be additionally subject to a biasing selective manually by the operator to control ink layer thickness and another adjustment in response to the speed of rotation of the duplicator. In one form, the sensing roller is able to skew so that a sensing switch at one end of the duplicator cylinder may be tripped before the sensing switch of the other end of the cylinder, for the purposes of providing a control which at least to some extent is responsive to local thickness of the layer. A further possibility envisages providing several different such rollers which between them cover the entire axial extent of the cylinder and thus they are each able to control the application of ink locally.

Title: Methods of engraving workpiece surfaces by etching
IPC: G03F7/24
Filed: 1979-11-23
Abstract: There is provided a method of engraving a workpiece surface 14 by etching using a thin flexible support foil 18 which carries a dissolvable pattern 20 made of a dye opaque to light.

Title: A method of moulding shaped articles and an apparatus for carrying out the method.
IPC: B29C53/24
Filed: 1979-12-10
Abstract: Shaped articles, such as corrugated sheets, are manufactured from a dry mixture of mineral powder and organic binders which, from a dosage device (9), is applied in a layer in a mould (12) which defines an optionally corrugated substratum. A good adhesion to the powder mixture is imparted to the surface of the substratum, preferably by applying a surface layer of a mixture of a binder and mineral powder. The mould (12) is advanced under the dosage device (9) and under a special shaping and compressing device (11) for the powder mixture. The contact face of the device (11) has a profile adapted to the shape of the articles, is mounted behind the dosage device transversely across the entire width of the mould (12) and is inclined a few degrees relative to the plane of mould travel so that the relative movement of the contact face of the device (11) ensures a uniform compresson of the powder layer (13). The compressed powder mixture is then hot-pressed into shaped articles. The apparatus comprises moulds (12), which define optionally corrugated substrata, heating devices, pressing devices and dosage device (9), behind which there is mounted a shaping and compressing device (11), as described above. During the advancing operation the moulds (12) may be fixed in the proper position in that they are placed on their respective suction boxes (15). The suction boxes (15) are interconnected to a chain, and their surfaces correspond to the lower surface of the moulds (12). The suction boxes (15) are provided with holes for the provision of vacuum under the moulds (12).

Patent ES-8403648-A1 (ES)
Title: Self rupturing gas moderator rod for a nuclear reactor
IPC: G21C7/22
Filed: 1982-01-22
Abstract: An arrangement for controlling the moderation of a nuclear reactor which includes multiple fuel assemblies each of which includes top and bottom nozzles with fuel rods and control rod guide thimbles located therebetween. Certain ones of said assemblies include at least one tube initially filled with a gas. One end of the tube rests on the lower nozzle upper surface while the upper end terminates at a point just below the lower plate in the upper nozzle. A spike immovably fixed in the lower plate of the upper nozzle is directed downwardly toward the end of the tube. As the tube expands or grows during operation in a reactor, and at a point where the criticality factor may proceed to less than one, the expanded tube will be pierced by the spike and thus permit the escape of gas from the tube which is then replaced by water coolant circulating through the reactor. The additional water represented by the filled tube will act to slow down fast neutrons to a thermal neutron level and thus provide a greater amount of neutron effective in carrying forward the fissioning process.

Title: Method of and apparatus for manufacturing paper stringer tape for slide fastener.
IPC: B26D3/08
Filed: 1982-05-27
Abstract: A method of and apparatus for manufacturing a pair of paper stringer tapes for slide fasteners from a pair of blank paper strips of a continuous length. The blank paper strips are fed lengthwise through a guide roller assembly. A pair of parallel spaced scoring wheels is biased against one guide roller of the guide roller assembly. As the paper strips pass between the one guide roller and the respective scoring wheels, a pair of continuous prospective folding lines of a constant depth is formed on the blank paper strips along the respective inner longitudinal margin thereof. The inner longitudinal margin of each paper strip is folded on the folding line to provide a doubled thickness with a folded edge on which a row of thermoplastic coupling elements is to be mounted. The support of the scoring wheels enables them to move toward and away from the strip, either jointly or individually, to compensate for variations in paper thickness, whereby said constant depth is maintained.

Title: Braking device for lifts.
IPC: B66B5/28
Filed: 1983-07-05
Abstract: A plate is attached to a rail which moves vertically in a housing. The housing includes a brake which rubs on one side of the rail on the other side, there is a roller. A leaf spring is positioned between the housing and the roller. When the rail moves vertically in one direction, the roller is pushed progressively harder against the rail.

Patent ES-8501101-A1 (ES)
Title: Process and liguefied gas injection device for pressurising containers.
IPC: B65B31/00
Filed: 1983-09-12
Abstract: Containers 6, adapted to receive a product which does not of itself give off a gas, receive an amount of a liquefied pressurizing gas from a tank 1 provided with an outlet nozzle 3. The containers 6 are aligned on a machine 7 which conveys them, in the direction of the alignment, under the tank 1 which is provided with trunnions 2 and is oriented in such manner as to be pivotable about an axis parallel to the direction of alignment. A control device 8 regulates the angular position of the tank 1. The amount of the liquefied pressurizing gas received in each container depends on the angular position of the tank relative to the vertical position. Thus, in the case of containers having a round section, the amount of liquefied gas received in a container is maximum when the nozzle is on the line of alignment of the containers and passes along a diameter of the container section and smaller when the tank has been pivoted away from its vertical position and the nozzle passes along a chord of the round container section. The invention is particularly applicable to the pressurizing of cylindrical cans adapted to contain non-gaseous drinks.
