Title: Transmission of magnetic alternating fields
Inventor: SCHALLER HERBERT
IPC: H04B5/00
Filed: 1981-02-20
Abstract: The invention relates to a circuit arrangement for the transmission of magnetic alternating fields over a non-ferromagnetic distance and relates to the wireless transmission of audio-frequency signal currents to an electro-acoustic transducer. The audio-frequency signal currents generated in a first area are transmitted via a wireless link to a second area in such a way that an electro-acoustic transducer is excited here in proportion to the signal currents. The invention comprises a device for magnetic audio-frequency transmission such that, according to Figure 1, the low-frequency information (UNF) is applied by means of a series resistor (1) to the primary winding (2) of a constant-current transformer (3) comprising a U-shaped iron core (4), a yoke (5) and the secondary winding (6) wound on it and the generated magnetic leakage flux (7) passes through the non-ferromagnetic medium (8) so that alternating currents are generated by induction in the secondary coil (5) which are proportional to the current passing through the primary coil. These alternating currents are fed to an electro-acoustic transducer (9), e.g. a loudspeaker, and radiated as sound signals. <IMAGE>
Patent DE-3106918-A1 (DE)
Title: Movable, multilayered heat-insulating means
Inventor: HEYDWOLFF MICHAEL VON
IPC: E06B9/174
Filed: 1981-02-25
Abstract: The invention serves to reduce the heat loss of translucent surfaces, preferably for greenhouses, exhibition halls and sports areas. Since the translucency is not required at night, an opaque insulation can be placed in front of the surfaces when it is dark. In its simplest state, the heat-insulating means comprises a translucent sheeting and a foam web resting thereon. First of all, the sheeting is unrolled and fastened on securing means. In order to reduce the passage of heat through the sheeting, a foam web is laid thereon. This thus results in a wall which separates the translucent outer surface, e.g. window, from the heated interior. When it becomes light, the foam web is rolled up first of all, said web being pressed together at the same time in order to save storage space. The sheeting can then be rolled up. The drawing shows use of the heat-insulating means in a greenhouse.

Patent DE-3117544-A1 (DE)
Title: Dowel setting in concrete road construction
IPC: E01C23/04
Filed: 1981-05-04
Abstract: In the production of concrete roads, the longitudinal dowels are set by means of supporting baskets which are incorporated in recesses prepared beforehand by the subdivided stripping plate of the finisher and continuing up to the road bed. For this purpose, the stripping plate forms in the direction of travel behind each recess a heap of concrete which a downstream stripping apparatus channels into the recess. The second stripping apparatus is guided behind the finisher since the supporting baskets have to be incorporated beforehand. Then the cross-dowels are also set individually by means of another vehicle and a vibrating apparatus. The invention is based on the object of providing a moving apparatus which sets the dowel automatically and dispenses with both the personnel required hitherto and the supporting baskets for positionally accurate orientation of the dowels. This object is achieved with a moving apparatus in which the first stripping apparatus dips into the concrete subbase only as far as the subsequent bearing level of the longitudinal dowels and forms a shallow recess into which dowel laying devices arranged in the apparatus deposit the longitudinal dowels automatically. The concrete suspension produced beforehand by the stripping apparatus is channelled into the recess by means of the second stripping apparatus. Advantageously a digging member is also incorporated in the apparatus, which member produces short transverse grooves for in each case one cross-dowel, a transverse stirrup laying apparatus arranged behind the digging member depositing the cross-dowels individually. A smoothing board also integrated in the apparatus and having a stripping plate then also fills up the transverse grooves with the inserted cross-dowels so that the finished concrete road cover having a plane and smooth surface is present behind the vehicle.
