Abstract: 762,487. Torsional vibration dampers. HINDMARCH, T. Sept. 22, 1954 [Sept. 30, 1954], No. 26819/53. Class 108(3). [Also in Group XXIX] Torsional vibrations or cyclic variations are eliminated in a hydraulic coupling by valves which allow flow through the coupling only when the pressure of the hydraulic liquid is above or below a predetermined range. When the pressure is within the range the coupling is locked. The coupling is of the gear wheel type having an internally toothed member 5 secured to a casing 2 carried by the driving shaft 1 and planet gears 6 carried by a part 9 connected to the driven shaft 4. Passages 10, 11 extend from the suction and pressure sides of the gears 6 and valve means 12 (shown only diagrammatically in Fig. 1), is provided in the passage 10. Valve means may be provided in both passages 10 and 11 if torque is to be transmitted in both directions of rotation. Fig. 4 shows, in more detail, the construction of the valve 12. When the passage 10 is subject to pressure, the valve 15 moves to compress a spring 16 and restrict the flow through ducts 18, 19 and eventually cuts off the flow. A further rise in pressure moves the valve to compress a spring 17 and re-establishes the connection between ducts 18, 19 and relieves the pressure.

Abstract: 1,058,437. Centrifugal strainers. CESKOSLOVENSKA AKADEMIE VED. June 28, 1965 [July 4, 1964], No. 27306/65. Heading B1D. A centrifugal strainer comprises two drums 1, 2 having closed ends 5, 6 and whose cylindrical surfaces are formed by axially extending bars 3, 4, the drums being arranged one within the other so that the bars interlock, and the end walls having slots, 7, 8 through which is threaded a length of filtering band 13, whose successive convolutions extend both inside and outside the drums to form a continuous, toroidal coil which completely encloses the cylindrical walls of the drums. The shaft 11 of the inner drum 2 extends within the hollow shaft 12 of the outer drum 1, and is so arranged that the axis of the inner drum may be tilted relative to that of the outer drum whereby the rotation of the two drums causes the toroidal band to move axially within the drums from the closed end to the open end. By this means slurry delivered by pipe 18 is filtered and the solids are discharged over the open ends of the drums by the movement of the band 13. Both drums may be driven independently or the outer drum 1 may be driven, thereby rotating the inner drum by the interlocking of the bars. Filter aid may be supplied to the closed end of the drums prior to supplying the slurry to be filtered to the pipe 18, and additional washing pipes may be supplied axially outwards of the pipe 18. Adjacent convolutions of the fabric band inside the drum may overlap. The mutual inclination of the drum axes may be varied in order to vary the speed of the band 13, this variation being achieved preferably by displacing the two drums in opposite directions so as to maintain the centre of gravity fixed. The fixed housing 14 may have annular partitions to collect liquids passing through different parts of the drums, and the housing may be closed and filled with inert gas. Band 13 may be of cotton, rayon, glass fibre or fine metal wire. The general orientation of the strainer axis may be horizontal as shown, or vertical or inclined.
