    Abstract: A device for the thermomagnetic recording of information on a highly coercive magnetizable recording medium. For this purpose is used, for example, a video recorder of the "helical scan" or "transversal scan" type whose drum has a co-rotating mirror and system of lenses with which an energy beam is directed and focussed on the recording medium at a small distance in front of the recording gap of the magnetic head. As a result of this the coercive force of the recording medium is locally reduced while using a very short heating time so that the medium can be recorded there by the head.

    Abstract: A device for scanning patterns, e.g. optical patterns, in which on the surface of a piezo-electric material Bleustein-waves are produced, while in the material or in a semi-conductor layer deposited on the surface a drift field is produced. Said drift field pulsates between two levels, a low level at which the gain of the surface wave is independent of the "exposure" pattern and a high level at which the surface wave is locally amplified in accordance with the "exposure" pattern.

    Abstract: An image magnifier for an image transfer apparatus comprises a multitude of fibres (2) arranged in laminar fibre arrays (3). The fibre arrays (3) are superimposed at the entrance face (4) and are disposed at the desired pitch from each other at the exit face (5). The fibre arrays (3) also extend at a minimal angle to the exit face (3). In the fibre arrays (3) the pitch of the fibres (2) decreases to the same pitch as that of the fibres (2) at the entrance face (4) within a minimal distance from the exit face (5), in such a way that the fibres (2) join each other substantially at the level of the orthogonal side (6) of the rectangular exit face (5). From this location the fibres (2) extend as a strip of parallel fibres in the direction perpendicular to the orthogonal side (7) of the exit face (5) and are subsequently bent towards the entrance face (4). By thus stacking the fibre arrays (3) the image magnifier has a much smaller depth at the location of these parts of the fibre arrays (3) where the pitch of the fibres (2) changes from the pitch at the exit face (5) to the pitch at the input face (4) than at the location where the fibres (2) are arranged in strips. This smaller depth is utilized in order to accommodate one or more image-display devices with associated optics and electronics. The images of the image-display devices are presented to the entrance face (4) and can be observed in magnified form at the exit face.

    Abstract: A magnetic memory device in which information is stored in the form of strip domains in a layer of magnetic material supported by a layer of ferromagnetic material. The ferromagnetic material contains a pattern of alternately magnetized strips for sustaining a magnetic field periodically varying in a first coordinate direction and directed transverse to the domain layer. The device also includes a generator for receiving and converting data into configurations of the strip domains in the plate.

    Abstract: An apparatus is described for converting cinematographic images into video signals. The film gate in which a frame to be scanned is located is illuminated uniformly. The film is scanned by means of a rotatable scanning mirror, which with the aid of an imaging system images one line of the film frame onto one row (three rows for color film) of radiation sensitive detectors. The detectors of a row are read sequentially. The illumination beam has a large aperture angle in a first plane transverse to the direction of film transport and a small aperture angle in a plane transverse to the first plane. The film movement is detected with the aid of a sprocket hole detection system, in which an elongate narrow light spot, whose longitudinal direction is transverse to the direction of film transport, is projected onto the strip of film with the sprocket holes. The position of the scanning mirror is detected with the aid of two gratings of special shape.

    Abstract: A device for testing magnetic thin layers for defects, in particular "bubble" films in which a magnetic medium in which a recurring pattern of elongate areas magnetized alternately in opposite senses is recorded is moved relative to the layer while the layer is opposite the magnetic medium so that a corresponding pattern of mutually parallel strip-shaped "bubble" domains is formed in the film. Deviations in said pattern are an indication of defects in the film.
