Abstract: 452,967. Reeds and beat-up motions for looms. SOC. ANON. A. SAURER, Arbon, Switzerland. March 12, 1936, No. 7465. Convention date, March 23, 1935. [Class 142 (iii)] In a loom having a divided reed which rocks up and down effecting a slight beating-up motion, an additional beating-up motion is effected by giving the spindle about which the reed rocks a to-and-fro movement in the direction of the warp threads. The spindle 5 is pivotally connected to a fixed shaft 25 about which it is oscillated alternately by a cam surface 20 to the left and a spring 28 to the right. A cam groove 15 effects, via arm 18, the up-and-down movement of the reed 3, 3a. In modification the spring is dispensed with and the roller 21 on the end of the arm 23 runs in a second cam groove in the disc 14. In another modification the shaft 5 is journalled in a toothed slide reciprocated by a toothed sector receiving motion from the cam surface 20.

Abstract: 1,024,198. Centrifugal strainer separators. MASCHINENFABRIK CHAM A.G. Feb. 25, 1963 [March 1, 1962], No. 7519/63. Heading BID. A filtering centrifuge comprises filter pads 18 extending along the outer faces of conical filter elements 6 stacked on a pot-shaped drum 2. The hub plate 7 of each element has a rib 8 with perforations 9 enabling liquid supplied through tube 31 to flow into cone-shaped annular spaces 26 between the elements. The liquid then flows inwardly through the filter pads and escapes through radial and axial passage 11, 10 in the hub plates and axial bores 28, 29, in a conical cap 3 on the drum. Layers of impurities collect on the filter pads until they are disintegrated and thrown off by centrifugal action. The impurities pass to the sludge room 27. The axial displacement of the bores beyond the annular overflow gap 33 governs the pressure difference across the filter. The filter pads 18 are secured to the elements 6, by clamping rings 19, 20. In a further embodiment, a screen insert may be arranged in the annular gap between the outer surface 12 of a shell 6 and its associated filter pad 18.

Abstract: 573,152. Determining physical qualities of materials. ARMOUR, A. M., WALLEY, J. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 21, 1943, No. 8146. [Class 37] An arrangement for detecting faults in specimens of electrically conducting non-ferrous materials comprises means for subjecting the specimen to the action of a constant magnetic field, means for producing relative rotation between the specimen and magnetic field about an axis transverse to the direction in which the magnetic field acts, and search coil means arranged for detecting any variation of the induced cross-field whereby to provide an indication of the presence.or absence of a fault in the specimen. Fig. 2 shows an arrangement for detecting flows in a cylindrical specimen r of a non-magnetic alloy. The specimen is supported on a rotatable platform b having means hj, hk for centering the specimen accurately between the poles of constantly energized electromagnets en, es carried on a magnetic yoke y. The platform l is rotated at a constant speed of about thirty revolutions per minute by a motor d. The induced cross field is picked up by two pairs of search coils C<1> C<2> or C<3> C<4> arranged in series and connected to a galvanometer a. The coils of each pair are oppositely arranged so as to eliminate the effects of mechanical inaccuracies. The existence of a flow causes a change in the cross field at twice the frequency of revolution. This is shown by deflections on the meter a, which is selected to have a natural frequency of vibration equal to that of the fluctuations. The sensitivity is increased by providing the search coils with high permeability cores. Different regions of the specimens are tested by moving the magnet assembly axially along guides m by means of motors q and chain and counterweight mechanism.
