    摘要: A reflector antenna arrangement can transmit and receive both infrared (IR) and millimeter wave (RF) radiation. The arrangement includes a main reflector (1), a subreflector (2), an IR feed system (4), an RF feed system (3), a radome (5), and a bispectral window (6) arranged in an opening provided in a central area of the main reflector (1). The RF feed system is oriented so that the RF radiation path includes a double reflection from the subreflector and from the main reflector, while the IR feed system is arranged directly behind the bispectral window so that the IR beam path extends directly through the bispectral window without reflecting from the main reflector or the subreflector. The bispectral window has a high reflectance for the RF radiation and a high transmittance of the IR radiation. The bispectral window is made of a dielectric material and has rotationally symmetrical front and back surfaces, whereby the front surface contour is optimally matched to the front surface of the main reflector and the back surface contour achieves an optimal reflectivity of the RF radiation and an optimal transmissivity of the IR radiation. Undesired influences between the IR radiation and the RF radiation are avoided by the separation of the signal beam paths.

    摘要: Test carrier for the analysis of fluids with a test field (7) held in a frame (2), in which the frame (2) comprises a top part (3) and a base part (4) and at least the top part (3) comprises a test field opening (6) through which a sample fluid can be applied to the surface (7a) of the test field. Simplified handling and improved analytical reliability are achieved by the fact that the base part (4) comprises a seat (16) for the test field (7) which is surrounded by positioning elements (15) which are higher than the test field (7). The test field opening (6) is greater than the test field (7), so that the rim (18) of the test field is visible. The top part (3) comprises pressure tongues resting on the surface (7a) of the test field (7) and projecting into the test field opening (7).

    摘要: Test carrier for the analysis of fluids with a frame (2) consisting of at least two parts surrounding a test field opening (6) and with a test field disposed in the test field opening (6). In order to provide such a test carrier with frame with which it is possible to assemble the test field out of several test layers manufactured separately from one another, it is proposed that the test field be designed as a test layer package (7) with test layers (10, 11, 12) resting loosely on one another, the frame (2) comprise two shaped pieces of plastics material, one of which serves as base part (4) and comprises a seat (16) for accommodating the test layers (10, 11, 12), while the other serves as lid part (3) and comprises a bearing surface (17) resting on the topmost layer (10) of the test layer package (7). The lid part (3) and the base part (4) are in addition designed with elastic properties so that the pressure with which the bearing surface (17) presses onto the test layer package (7) is substantially constant in the tolerance range of the thickness of the test field package (7).

    摘要: A baling machine according to the invention has a frame having walls defining an elongated compaction chamber having a front end provided with a transversely open intake to which a stream of crop is fed substantially continuously. At least one compacting member is periodically displaced in the chamber between a front position forward of the intake and a back position rearward of the intake by an appropriate drive so as to rearwardly compact crop in the chamber. A plurality of pushers are each displaceable between an advanced position projecting into the chamber and only partially blocking the intake and a retracted position substantially out of the chamber by a linkage that advances the pushers into their advanced position only when the member is rearward of the intake and of the pushers. Thus advance of the pushers into the advanced position immediately after movement of the compacting member rearward past the pushers parts the stream of crop between the pushers and compacting member. A plurality of tie needles engages across the chamber rearward of the pushers in the advanced position thereof so as to pull respective ties across only when the pushers are in the advanced position. Normally according to the invention each of the pushers is formed with a throughgoing guide hole and each of the needles can pass through a respective one of the holes in the advanced position of the respective pusher.
