1,066,457. Agitators; comminuting apparatus. P. WILLEMS, [trading as FORSCHUNGS-INSTITUT PROF-ING.-CHEM. P. WILLEMS]. Aug. 11, 1964 [Aug. 21, 1963], No. 32669/64. Headings B1C and B2A. [Also in Division F1] A rotatable agitator has at least one disc with cutting projections (e.g. as at 6) and with an undulating surface which may be smoothly curved or consist of a number of plane sectors; the cutting projections may take the form of a toothed edge (see Figs. 3-7 not shown) and there may be openings 5. It may be mounted on a shaft with disc(s) not having projections, and/or be arranged to cause circulation in a container (Figs. 3 and 4, not shown) or be closely surrounded by a casing to form a centrifugal pump (Fig. 10). Both the rotor and the casing inner surface may then be toothed (see Fig. 11, not shown). A rotor 23 with toothed edge 24 may co-operate with a stator cage 25 consisting of an array of parallel or twisted rods 26 with detachable internal teeth 28, the whole being mounted in a pump casing 27, Fig. 13. |
