Patent ES-8306854-A1 (ES)
Title: Method of manufacturing of an anticorrosion coating on solar absorber.
IPC: F24J2/46
Filed: 1982-02-26
Abstract: Solar absorber with a selectively absorbing surface coating, and also a manufacturing method therefor. Selectively absorbing surface coatings are applied to solar absorbers in order to improve their efficiency. Various coatings of this type have been disclosed, but it has hitherto not as yet been possible to achieve high selective absorption and good corrosion resistance simultaneously at an acceptable cost. The object is consequently to provide an effective corrosion protection for selectively absorbing surface coatings on solar absorbers without impairing their efficiency in doing so. According to the invention, to solve this problem it is proposed to apply a corrosion protection coating made of polytetrafluoroethylene (PTFE), preferably in a thickness of 1 to 6 mu m, to a selectively absorbing surface coating. Figure 1 shows how the emission coefficient epsilon varies with increasing thickness of the protective coating. The values for PTFE and Vestar (R), a known product for similar applications, have been plotted. For the same coating thickness, PTFE is not only substantially more advantageous than Vestar (R), but it can also readily be applied in a smaller layer thickness, so that, if the corrosion protection coating according to the invention is used, no appreciable impairment of the emission coefficient has to be accepted.

Patent ES-8402036-A1 (ES)
Title: Sewing machine equipped for producing shaped seams
IPC: D05B69/00
Filed: 1983-04-05
Abstract: A sewing machine for sewing shaped seams comprises equipment for exactly positioning an end stitch. By means of two edge sensing sensors provided one after the other in the feed direction, a pulse generator coupled to the main shaft, and a microprocessor, the difference between the desired feed length of the workpiece and the actual feed length thereof is determined. A microprocessor controls a step motor for adjusting a stitch setting device, the adjustment being a function of the difference between the desired and actual feed lengths of the workpiece and of the angular position of the main shaft at the instant of response of the second sensor. In this way, the length in excess of the last stitch which, without a correction, would extend beyond the predetermined end point, is uniformly distributed among the last stitches of the seam, while at the same time taking into account slippage between the feed dog and the workpiece.

Patent ES-8607742-A1 (ES)
Title: Method and apparatus for reducing the gas content of a liquid
IPC: B01D19/00
Filed: 1985-05-23
Abstract: In a method of reducing the gas content of a liquid in which the liquid is propelled, preferably in a closed circuit, by a centrifugal pump (1), an improved degasification capability is achieved by extracting a portion of the liquid from the suction side of the pump blades (5, 18) in the region of the impeller axis, preferably via a passage (20) extending through a hollow drive shaft (21) of the impeller (14), and conducting this portion of the liquid through a liquid stilling zone (55, 56) where fine gas bubbles are separated from the liquid. The degassed liquid is preferably returned to the liquid in the inlet pipe (15) upstream of the pump (1), where it is set in rotation by a helical member (10). The liquid extracted from the pump (1) may be sucked out by means of an auxiliary rotary pump (3), or it may be entrained by injecting a high speed stream through a venturi nozzle (39) housed by the impeller (14) coaxially with the hollow drive shaft ( 21). In this latter case the degassing of the liquid in the stilling zone (55, 56) may be assisted by an atomizer (44).

Title: Method and apparatus for uniformly debossing and optionally aperturing a moving plastic web.
IPC: B29C59/06
Filed: 1985-08-28
Abstract: Apparatus for uniformly macroscopically expanding and, if desired, aperturing a plastic web. This is preferably accomplished by supporting the plastic web on a moving three-dimensional forming structure which is supported in a fluid pressure differential zone by a stationary support member. By providing a relationship between the size and pattern of the apertures in the stationary support member and the size and pattern of the apertures in the three-dimensional forming structure, substantially all of the apertures present in the forming structure are unobstructed by the stationary support member at some point during the forming structure's traverse of the fluid pressure differential zone. Thus the resultant plastic web is uniformly debossed and, if desired, apertured in the pattern of the three-dimensional forming structure.
