Abstract

841,207. Sifting apparatus. MULLER, J. Nov. 1, 1956 [Jan. 18, 1956], No. 33368/56. Class 117 [Also in Group I] A sifting element comprises assembled annular discs or frame-like strips having grooved faces in facial contact, the grooves 2 being arranged at a common inclination to the centre and running from the inner towards the outer edge. The inclination of the grooves on opposite faces of the discs 1 is of the same hand so that when the discs are assembled the grooves of one disc cross the grooves on the adjacent disc. The grooves are arranged tangentially to an imaginary circle 4 in the disc and concentric with it and they increase in depth in the direction of liquid flow: they may be curved and may be constructed for inward or outward flow. Fig. 14 shows a candle made up from the discs. A flanged support member mounts it on a partition in a sifting device and supports a pile of annular discs 23 surrounding a perforated tube 13 secured to the support 10 and carrying a fixed nut 22 into which screws a rod 16 pressing on to an upper cup 14 through a spring 21 to clamp the pile of discs to the support 10.
