Abstract: 1404164 Traverse generating and controlling mechanisms F M N SCHUSTER & CO 6 Oct 1972 [8 Oct 1971 13 Jan 1972] 46088/72 Heading D1J A cross-winding apparatus comprises a casing containing a rotary cam drum 10 which drives a thread guide 7 mounted in the casing, a first mechanism to gradually reduce the traverse as the diameter of the thread package increases and a second mechanism drivable by the cam drum to superimpose a periodical increasing and decreasing change of the traverse. The cam drum 10 is driven from a friction roller 4 which also drives the package 3. The said first mechanism comprises an inclined guide rail 21 which superimposes an angular motion on the linear traverse of thread guide 7. The inclination of rail 21 is determined by a tapered cam 26 which is moved via link 25 in response to the package size. The cam 26 is also displaced periodically sideways by a cam 33, which comprises the said second mechanism, and is driven by a worm drive 38, 39. A double lever 28/30 is interposed between cams 33 and 26, the relative positions of the arms of lever 28/30 being variable to adjust the initial inclination of rail 21. Another cam 46, or alternatively a linkage from the rail 21 cyclically varies the drive ratio between the friction roller 4 and the cylindrical cam 10 to prevent pattern winding. The variable drive may be provided by tapered friction wheels with a movable intermediate wheel, Fig. 10 (not shown) or by flat discs with a movable pair of friction wheels at right angles to them, Fig. 11 (not shown).

Abstract: 1,072,397. X-ray testing apparatus. INSTITUTE OBSCHCHEI I NEORGANICHESKOI KHIMII " N.S. KURNAKOV." Dec. 11, 1963, No. 48891/63. Heading H5R. X-ray apparatus for testing crystals over a wide range of temperatures, for example by X-ray diffraction, or for measuring thermal expansion by radiographic methods has means for mounting the sample to be irradiated and for rotating and oscillating the sample, and is arranged such that either a heating or cooling chamber may be mounted around the sample and interchanged without disturbing the sample. The apparatus arranged for high temperature work, Fig. 2 (and Fig. 3, not shown), involves a high temperature cover defining the working chamber 6, in which is positioned a mono- or poly-crystal sample 7 fixed in a chuck 8, connected into the goniometer head 9 which can be rotated or oscillated in response to a driving unit 10. The head 9 is decoupled from the driving unit 10 when precise optical adjustment of the sample is necessary, a fluorescent screen 41 with cross-hairs being used to line up the sample with the X-ray beam. The beam is projected on to the sample through an orifice in the collimator 12 and collected by a trap 13. The sample is heated by two bell-shaped resistance furnaces 14, the windings of which are of particular materials suitable for the temperature ranges required (0‹ to 1300‹ C.). measurement of the temperature is by an annular thermocouple 15 which can be moved along the length of the sample by a screw mechanism 16. The walls 11 are cooled by water supplied to channels 17 via a nipple 18. The temperature variation through the length of sample 7 can be reduced by a variable resistance in the control circuit (Fig. 5, not shown). The chamber 6 is sealed by a seal (20) and bolts (21), and a vacuum seal (23) round the electrical entry leads, the collimator having a beryllium window. An air-tight bellows 24 surrounds the mechanism 16. The nipple 26 acts as an outlet for evacuation of the chamber 6 and as an inlet for gas. The X-ray film is held by a spring (30) in a holder 27, and receives X-rays reflected from the sample through the circular slot 25. The holder 27 is movable on guides and thus a series of radiographs may be taken with a single loading. For low temperature work (to - 269‹ C.) a low temperature cover (Fig. 4) replaces the high temperature one, being fully interchangeable with it. Cooling of the sample is carried out by liquid nitrogen or helium. Measurement of temperature is carried out with a similar annular thermocouple (38) to that used with the high temperature cover. A magnetic coil (39) is used to provide temperature control.
