Inventor: BOEMERS JOSEPH JOHANNES PETRUS
IPC: B29D28/00
Filed: 1980-12-19
Abstract: The invention relates to a process for the manufacture of network packages from reticulate webs obtained by stretching, fibrillating and spreading of a film of organic polymeric material. Network packages according the invention are obtained in that:
     a. one or more reticulate webs (3), one on top of the other, are continuously supplied and laid onto a carrier (4);   b. the reticulate webs are folded zig-zag on this carrier (4);   c. the folded network is continuously transported in a direction virtually normal to the direction in which the reticulate webs are supplied;   d. further, at one or both sides of the resultant folded network, reticulate webs are applied, which webs are stretched longitudinally and in the direction of transport, fibrillated and spread, and are supplied in the direction of transport of the folded network and joined with it;   e. the resultant combination of reticulate webs is carried off;     
the rate of supply of the reticulate webs to be folded and the rate of discharge of the folded reticulate webs being chosen so that the angle between two successive folded sides of reticulate webs is between 1 and 50°C and in particular between 1° and 20°.
     By preference only at one of the two sides of the resultant folded network package, reticulate webs streched in the transport direction are applied, and at the other side only one or two of such webs. 
     The resultant folded network packages are integrated into a whole by welds at the sides and are passed between heated rollers (7).

Abstract: A facsimile system is so controlled as to reduce four successively scanned source documents and print all four reduced copies on a single copy page. The system prints one of the source documents (44) in each quadrant of the copy document. The images are reduced in the horizontal dimension by discarding every other picture element in the scan image and in the vertical dimension by increasing the speed of the scanner (40) so that the size of the picture element in the vertical dimension is doubled. At the receiver, two scanned and reduced images will be printed on the left-hand half of the copy document (12). Subsequently, two additional scanned and reduced images are printed on the right-hand half of the copy document. When printing the right-hand half of the copy document, the printer is controlled to start printing at the horizontal mid-page of the copy document rather than the left-hand edge of the copy document.

Abstract: A process for the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols which contain alkyl substituents in both ortho-positions, but not in the para-position, by oxidative coupling reaction with oxygen at between 25 and 50 DEG C in the presence of a catalyst complex comprising  a copper salt and an organic amine and in the presence of a solvent in the range from 1:1 to 20:1 parts by weight, at least 3 per cent by weight of an alkyl-substituted phenol being used which carries a graftable or oxidisable isopropyl group in the 2- or 6-position. A particularly suitable alkyl-substituted phenol is 2-isopropyl-6-methylphenol. In a preferred procedure, an ethylenically unsaturated monomer, such as styrene or methyl methacrylate, is graft-polymerised onto the isopropyl-containing polyphenylene ether. The isopropyl group of the polyphenylene ether can be converted into a hydroperoxide group by oxidation, and the resultant polymer can be used for free-radical polymerisations.

Abstract: A video tape recording/reproducing apparatus for reproducing video signals recorded in successive parallel tracks on a magnetic tape, includes a magnetic head movable in a direction generally along each of the tracks in a scanning path from a beginning end to a concluding end thereof for reproducing signals recorded therein, and a bi-morph leaf for mounting the head and being operative to deflect the head in a direction transverse to the direction along the tracks. During the scanning operation, the bi-morph leaf is supplied with a dithering signal for wobbling the head transversely with respect to the longitudinal direction of the record tracks, a tracking error signal to correct deviations of the head trace from the tracks to be scanned and a slant compensation signal to correct any inclination tracking error of the head. During the non-scanning operation, a jump signal is supplied to the bi-morph leaf for deflecting the head to accurately scan the beginning of the tracks. The present invention also includes a sample and hold circuit and a comparator circuit for producing a polarity signal corresponding to the direction of any deviation between the scanning trace of the head and the track then being scanned thereby, at the beginning end of the scanned track, and an UP/DOWN counter for producing and storing a control signal and for supplying the control signal to the bi-morph leaf so as to control the latter to deflect the head to accurately scan the beginning ends of the tracks, the counter being controlled by the comparator circuit to change the value of the stored control signal by an incremental amount by counting either UP or DOWN during each scan in accordance with the direction of the deviation at the beginning ends of the tracks.

Abstract: In a system for captivating heat from solar radiation by means of collectors which contain absorbers, from which the heat produced is led off by means of a liquid heat transfer medium, the narrow elongate collectors are covered on the side turned towards the solar radiation by a transparent sheet and have both on the side of the absorber turned towards the solar radiation and on the side turned away from the solar radiation an air gap which runs in the longitudinal direction, is flowed through by air and conducts the outside air which is guided past along the absorber in such a manner that the outside air makes direct contact with the wall of the absorber. There is also provided a heat pump, by means of which the low temperature of the heat transfer medium can be raised to the necessary value, when the supply of solar radiation striking the collector is not sufficient to reach the necessary operating temperature. This system thus exploits both direct and diffuse solar radiation and also the heat content of the outside air, of the air moisture and of the latent heat.
