Abstract: Ethylene polymers are produced at pressures between 1000 and 4000 atmospheres and temperatures of from 120.degree. to 300.degree. C in a reaction zone having an 1/d ratio of from 10:1 to 20:1 while shear forces act on the reaction mixture. The ethylene is fed continuously and radially to the reaction zone at a velocity of from 2 to 20 m/sec. The average residence time of the reaction mixture in the reaction zone is from 20 to 90 seconds. The products show a broad molecular weight distribution and are particularly advantageous for use as extruded coatings.

Abstract: The invention relates to a cartridge for a recording medium in tape or strip form and a transport apparatus for use with such a cartridge, both being favorably matched to one another according to the invention. The cartridge consists essentially of a housing which is composed of parts pivotally connected to one another and, in the closed position, completely encloses a roll of tape wound on a hub. In the open position of the cartridge, at least part of the roll of tape is so exposed that the roll can be rotated and the tape or strip scanned on the apparatus. The transport apparatus is provided with appropriately designed means for receiving the cartridge which, when some of its components are pivoted, swings apart the parts of the cartridge, which is placed upon the apparatus in the closed position, and thus opens the cartridge.

Abstract: The invention concerns a device for the non-destructive measurement of the remanent flux density of magnetic recording media, by recording a specific signal and reproducing the recorded signal by means of two pairs of magnetic recording and playback heads arranged opposite one another and perpendicular to the plane of the recording medium, the ratio of the distance between the individual magnetic heads of each pair of heads to the wavelength of the recorded signal being within a specific range, and the said distance being such that a magnetic recording medium is movable symmetrically between the pair of heads, a common measuring unit being associated with the playback pair. Further features of the device relate to the design of the magnetic recording and playback heads, the measuring unit and the rate at which the particular magnetic recording medium being tested moves between the pairs of heads.
