Patent ES-466961-A1 (ES)
Title: Hemostatic surgical felt and method of producing same
IPC: D04H1/54
Filed: 1978-02-14
Abstract: Haemostatic surgical felts with an average drape of 2 cm and an average loop softness of 4g, made from a tissue-resorbable polyglycolic acid polymer, are claimed. The polymer is spun into fibres with a thickness of 0.5-12 denier and the fibres are cut to a length of 6.35-76 mm. The chopped fibres are then randomly air laid into a fibre mat with a substance of 17-135 g/m2. The fibre mat is then passed between a pair of steel rolls with a textured surface having a patrix and a matrix. The surface temp. of the rolls is 149-190 degrees C and the rolling pressure is 0.89-1.79 kg/cm. The mat is compressed to form embossed depressions with an even or uneven depth of 0.025-0.075 cm and the resulting felt is cut into pieces of the required size. The felts are useful as haemostatic tissue-resorbable dressings for surgical use. They have good softness and drape characteristics, so that they can easily assume the shape of the wound and move with the movement of the tissue during the healing process.

Title: Video reproducing apparatus with variable delay means
IPC: H04N5/783
Filed: 1979-10-01
Abstract: A reproducing apparatus for television signals recorded on a magnetizable record carrier in the form of a tape comprises a rotatable transducer arrangement which for reading television signals which are recorded in adjacent oblique tracks which extend parallel to each other carries two magnetic heads of mutually different azimuth angles, whose azimuth angles correspond to the azimuth angles of the magnetic heads used during recording.
