    摘要: An antenna design includes a plurality of radiating elements which radiate electro-magnetic energy, and feeders which feed the electromagnetic energy to the radiating elements. The feeders have a supply network substantially at the same level in the antenna thickness direction. In order to achieve a small antenna with adequate properties for radio link usage, the radiating elements are arranged next to the supply network in the thickness direction and include box horn antennas which have a step, characteristic of a box horn, in the plane of the magnetic field.

    摘要: The invention relates to a conveyor chain, which comprises chain links (1) consisting of a barrel portion (2) and elongated side bars (3,4), the first ends of which are attached to the ends of the barrel, whereby the distance between the free ends of the side bars (3,4) corresponds to the length of the barrel (2) including the side bars attached to it. In order to enable the assembly of a chain of identical, mutually similar parts without tools, the surfaces located opposite each other at the free ends of the bars (3,4) of the chain links are provided with studs (5,6), the outer diameter of which corresponds to the inner diameter of the barrel (2) and the elasticity of the bar (3,4) material is such that the bars can be spread from each other to such an extent as to enable the insertion of the studs (5,6) of one chain link into the barrel (2) of another chain link.
