Patent ES-368319-A1 (ES)
Title: Method and apparatus for removing material by means of spark erosion
IPC: B23H9/06
Filed: 1969-06-13
Abstract: In a spark erosion process, a piezo-electrio element 6 secured to an electrode 10 performs a relaxation oscillation the oscillation period of which is determined by the current supplied to a capacitance formed by metal coatings 7, 8 on the element 6 and by the charge drained from the capacitance through the spark produced. A voltage is applied across the coatings 7, 8 by a variable current source 15 to cause the element 6 to move towards the workpiece which comprises a conductive layer 11 on an insulating body to be formed into an optical grating. When a spark is produced across the gap, the voltage across the coatings 7, 8 is discharged and the element 6 jumps back, the process being repeated to produce a relaxation oscillation. An additional capacitor 18 may be connected in circuit and a capacitor 17 and inductance 16 may be provided to control the spark energy. The element 6 is movable vertically by a rack and pinion 5 and horizontally by knobs 3, 4. When a workpiece having a contoured surface is machined, the gap width is kept constant by comparing the peak voltage at terminals 21, 22 with a reference voltage in a control device 20, the output of which is connected to a central electrode 19 and the coating 7 of the element 6. A plate 6b of the element 6 is caused to contract or expand according to the output deviation voltage V from the device 20, a plate 6a responding in an opposite manner, thereby causing the gap width to be kept constant. Alternatively the deviation signal may be used to control a motor which drives the pinion 5.

Title: Process and apparatus for melt spinning synthetic polymers
IPC: D01D5/088
Filed: 1970-02-03
Abstract: Synthetic polymers are spun vertically downwards through a spinneret, the orifices of which are so spaced that their centres are between 3À5 and 10 mm. apart, the filaments cooled by blowing a stream of gaseous cooling medium on to them at an angle of from 80 to 150 degrees to the direction of the movement of the filaments and supplementary heat is continuously supplied to the spinneret during the spinning process, the amount of supplementary heat being regulated such that it is not less than half the amount and not more than the total amount of heat removed from the spinneret by the gaseous cooling medium. The supplementary heat may be supplied by a radiator or by means of a heater in the spinneret. If a radiator is used, it may be aimed at the spinneret or parallel to the nozzle plate. The spinneret is preferably made of low carbon steel having an emissivity greater than 0À3. The process is suitable for use with polyesters, for example polyethylene terephthalate, polyamides such as nylon 6 and nylon 66 and polyolefines such as polyethylene and polypropylene. Steam may be used as a cooling medium. A latent crimp may be imparted to the filaments by cooling them from one side only. Specifications 1,262,811, 1,262,812 and 1,262,814 are referred to.

Patent ES-433286-A1 (ES)
Title: Injection nozzle for foaming machines
IPC: B29C39/00
Filed: 1974-12-23
Abstract: An injecting nozzle for injecting reactants into the mixing chamber of a foam machine mixing head wherein the needle which seals the nozzle opening also controls the communication between the feed conduit and the return conduit of the recycle system. The needle by means of an annular groove carried on its shaft or on the nozzle housing or by "means" of annular grooves on both allows the reactants to recycle through the return conduit when the nozzle opening is sealed but prevents such recirculation when the nozzle opening is open. Thus, the recycle path and the pouring path are identical or almost so and any dynamic disturbance upon changing of modes is eliminated.

Title: Method for improving print quality of coarse-scan/fine-print character reproduction
IPC: H04N1/411
Filed: 1978-03-30
Abstract: A directional biasing method enhances the print quality of coarsely scanned characters. A coarse scanning device produces analog signals that are compressed by encoding common information in a run length coding and encoding at least an edge of the character information according to a grey level indication. The data information is reproduced wherein the grey scale information is decoded to represent a finer print than the picture element scanned. The biasing and placement of the dots is set according to the grey scale of the surrounding picture elements. Eight sums are obtained of various groups of three peripheral picture elements corresponding to eight patterns located symmetrically on both sides of 4 bisecting lines, vertical, horizontal and two 45 DEG lines. A particular matrix of print dot placement is selected according to the largest pattern sum among the eight possible cases. The dots in each matrix are designed to being strongly biased toward the direction of the associated pattern.

Patent ES-480801-A1 (ES)
Title: Article comprising a substrate and an overlying processing layer of actinic radiation-sensitive material and process for fabrication of the article.
IPC: H01L21/30
Filed: 1979-05-22
Abstract: A phase compatibile polymer blend serves as a radiation sensitive lithographic resist in the fabrication of circuits and circuit elements. Radiation sensitivity is due to inclusion of a "modifier". Resist properties, notably stability to agents and ambients to be masked are attributed largely to a second component, the "matrix polymer". In an exemplary embodiment in which the blend is positive acting, fabrication including dry processing is dependent upon use of a resist blend of a vapor developing polysulfone and a novolac. The novolac, inherently soluble in alkaline media is rendered insoluble in the blend. Radiation initiated depolymerization results in volatilization of the modifier to render the irradiated portions of the resist soluble in alkaline developers. Modifier may function in other manner for example, it may undergo radiation initiated polymerization so as to insolubilize the blend in irradiated regions, so resulting in a negative acting resist. Effective isolation of lithographic from masking functions permits design of blends with high lithographic sensitivity, as well as good processing stability. The latter is sufficient to permit use in many dry processing procedures as practiced in direct writing, as well as in mask fabrication of large scale integrated silicon circuits.
