Abstract: 1,183,600. Self-cleaning filters. G. MAESTRELLI. 20 Dec., 1967 [13 Oct., 1967], No. 57781/67. Heading BID. A plurality of vane-shapedfilter elements D are secured to a common shaft F so that when the latter is rotated, portions of the solvent present in the chamber B are subjected to centrifugal motion and (by reaction against the chamber wall) centripetal motion, whereby the elements D are cleaned of accumulated dirt. The vane-to-housing separation 100 increases circumferentially. As described, the filter elements are similar to those of Specification 1181273 and the device operates similarly. As shaft F rotates (after filtration), the solvent is urged outwardly (arrows V, T) into space 100 until it meets baffle plate 112, which is axially longer than the elements D and so directs solvent radially inwards, arrows U (Fig. 1, not shown). It may be used as a dry-cleaning machine filter.

Abstract: A self-cleaning filter, particularly for dry-cleaning plants, comprising a liquid filled chamber wherein a plurality of filtering elements are radially housed in a circularly arranged pattern around a central free chamber zone. At least one centrifugal impeller is fitted within said free zone and suitably driven at time intervals by a motor shaft in order to cause the liquid be moved against and through said filtering elements for the cleaning purpose thereof.

Abstract: A solvent filter particularly designed for drycleaning plants, comprising a filtering assembly consisting of a plurality of elongated filtering elements supported by, radially extending from and evenly spaced about a shaft rotatably supported within a stationary casing coaxial to said assembly and provided with inwardly protruding ridges adapted for promoting a turbulent motion of the liquid in the spaces confined between adjacent filtering elements when said assembly is rotated within said casing, whereby the liquid is caused to lap the surface of said element and sweep the exhausted filtering powder and dirt thereof.

Abstract: 1,181,273. Liquid filter. G. MAESTRELLI. 15 June, 1967 [15 Feb., 1967], No. 27618/67. Heading B1D. [Also in Divisions D1 and D2] A filter used in the solvent circuit of a coin-freed dry-cleaning machine comprises a plurality of filter elements D, made of wire wound on flat frames of moulded plastics, having lozenge-shaped cross-sections and being radially arranged about and supported by two or three rotatable hollow shafts F. After a washing cycle, during which solvent passes continually through the filter and back to the washing tub, the solvent flow is stopped and the shafts are rotated or arcuately reciprocated by a common motor (64), creating turbulence in the dirty solvent around the elements and thereby washing the used, absorbent, filter aid and solids therefrom. Periodically a sludge outlet (72) in the housing floor is opened. In Fig. 2 and Fig. 3 (not shown) the elements D intermesh and turbulence is concentrated in zone H. In Fig. 4 (not shown) the elements of the different assemblies do not intermesh and there is less turbulence. Within the limits of the filter housing, additional filter elements may be added to each ring of elements, and further complete rings of elements may be mounted axially above the first on each rotatable assembly. The ends of elements open into hollow radial arms of plastics spiders between which elements are clamped, the spiders (G) open into the interiors of shafts F and these discharge filtrate by outlets (70). Sludge discharged by outlet (72) passes to a distillation plant which recovers the filter aid.
