The absorber takes the form of at least one plate with channels for a heat carrier and located in an insulated tray-shaped casing closed by a transparent cover plate (12). Between the cover plate and the absorber is at least one convection barrier. The cover plate (12) is divided into sections, the end joint edges of which facing each other are supported by window-type bars (26) supported against ...

A process for producing laminate sheets, films and the like provided with a varied surface finish is described in which a coating containing a means for structuring and/or for modifying the reflective behaviour of the surface of the laminate sheets, films and the like is used. In this process the coating containing the means is only applied to selected regions of a carrier material and is there at...

A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel, which is the rotor of a centrifuge, is designed to maintain its thickness dimension constant and yet facilitate its manufacture and cleaning by forming the rotor of a double mating ring in which the inner ring is split. This permits the inner ring to conform to the outer load carryin...

The metering of the yarn (14) which is drawn off and is to be wound onto spools (15) is carried out at each work unit (5) of the machine by means of a pulse counter (2), in which pulse counters (2) periodic pulses are transmitted (during active operation of the work unit) by a central system (1) which has an independent pulse transmitter (11) and an actuating element (16) for preselection of the c...

Method of tying an upper thread to a lower thread by means of a device having a splicing chamber formed with an elongated slot for laying-in and tying the threads, including mutually tying the threads by splicing with compressed air acting thereon from a side, moving a thread regulator from a thread take-up location to a thread delivery location for laying-in the threads into the elongated slot of...

Device for tying a first thread to a second thread by splicing with pressure gas, the device having a splicing chamber formed with an elongated slot for inserting and tying the threads, at least one pressure-gas channel terminating in an interior space of the splicing chamber, a thread regulator movable from a thread take-up position to a thread delivery position for laying the thread into the elo...
