Title: Speed change for magnetic tape recorders - has worm gear drive with belt drive changeover provided by motor reversal through centrifugal clutches
IPC: G11B15/44
Filed: 1977-03-11
Abstract: For normal operation the worn gear (4, 5) with a high reduction ratio transmits motion from a drive shaft (1) to the output shaft. For high speed rewinding of the tape a square cross section belt looped around a free wheel pulley (8) and a clutch coupled pulley is used. A similar clutch is coupled to the worm wheel. The two clutches are of the centrifugal type and respond to opposite drive shaft motions. On this basis a change from fast rewind speed to normal speed is effected by reversal of the motor rotation without any mechanical actuation.

Title: Process and device for the continuous spinning of viscose rayon
IPC: D06B15/00
Filed: 1978-10-25
Abstract: The removal of water from viscose rayon yarns in the continuous spinning of such yarns is improved by subjecting the yarns to the action of an air jet before the thermal drying treatment. The air jet impinges on the yarns adjacent their passage from the last liquid treatment zone to the drying zone and is directed approximately tangentially to the treatment roller, that is to the helicoidal path of the yarn. The removal of the water is completed by thermal drying. Up to 50% of the water content, and several times the dry weight of the yarn, is eliminated by the pneumatic treatment. The air jet is directed on the yarn by means of a slit-shaped nozzle having its larger dimension substantially parallel to the treatment roller. A plurality of yarns can be treated concurrently on the same device having a plurality of guide rollers.

Title: X-ray examination apparatus with an X-ray source mounted on a column movable in the longitudinal direction of the table.
IPC: A61B6/00
Filed: 1980-03-05
Abstract: The invention relates to an X-ray examination apparatus comprising a frame and a patient examination table which is slidably connected to the frame. This apparatus is particularly suitable for making Bucky exposures. The apparatus offers the advantage that it is very accessible from the sides, without mounting the guide rail (the guide rail supports the stand which supports the X-ray source) on the wall or the ceiling. To this end, a column which supports the X-ray source is movable in a longitudinal direction along a guide rail. The guide rail, in turn, is movable in the longitudinal direction on a carriage. The carriage, in turn, is movable in the longitudinal direction on a stationary frame. This results in a telescopic movement of the movable parts and in a displacement range which is larger than the width of the frame.

Title: System for recycling char in iron oxide reducing kilns
IPC: C21B13/08
Filed: 1981-03-23
Abstract: A method and means for improving the efficiency of the process for directly reducing ore containing iron oxide in a rotary kiln using a solid carbonaceous reducing agent, such as coal, introduced from the ore feed and discharge ends of the kiln, as both fuel and reductant, is disclosed wherein the charred coal or char found in the discharge product is recycled into the process at the discharge end of the kiln rather than the feed end as in the prior art.
