Abstract: A solvent parts washer of the closed cycle type has an additional, independently controlled continuously cycled pump which recycles the solvent through a bypass filter. The pump has a suction inlet at the bottom of the parts washer bin and continuously passes a flow of solvent through the pass filter. This is one of a number of filters, commonly known as paper towel or paper roll filters, in which a liquid to be filtered is forced at a high pressure and low flow rate along the interstices between adjacent compacted sheets of a filtering medium. Such filter media and filters have relatively low flow rates because of their cleaning (filtering) capability is by absorption rather than screening, but have an exceptionally high ability to remove particles down to the sub-micron level from a filtered liquid. An agitator pipe in the solvent return flow serves to flush particulate contamination into the filter pump inlet. The invention maintains the solvent substantially free of contamination above the 0.5 micron level.

Abstract: An apparatus for adapting a paper towel filter to utilize a range of paper towel or filter element sizes. A perforated end plate is provided to engage the ends of the filter element. An inwardly sloped truncated conical extension from the center of the end plate extends into the ends of the filter element roll, which seats along the conical extension, based on its inner diameter. A pipe sealing face is provided along the inner surface of the conical extension, at the end away from the end plate; this face sealingly encloses an axial pipe. The combination of two end plates, so mounted on an axial pipe, and enclosing a paper towel roll, forms a removable filter cartridge for a paper towel filter, which readily adapts to a variety of sizes of paper towel rolls.

Abstract: A revised sealing structure for an injection molded filter canister, which is resistant to leaks despite the periodic warping of the lid. A nearly square cross-section groove is placed in the body of the filter around the perimeter of the body open end. Within the groove is placed a "lathe cut" gasket; this is an elastomeric gasket having a precision rectangular cross section. On the lid, centered so as to be positioned opposite the groove in the body, and sized to be nearly centered in the groove, is at least one raised, circular ridge. With the addition of the ridge to the lid, in combination with the lathe cut gasket and the revised groove, that the lid may be easily placed in sealing contact with the body, and that the incidence of leaks is substantially eliminated in reinforced plastic molded filters. No special care or skill is needed of the workman in placing and fastening the lid to the filter body to achieve a tight seal.

Abstract: The invention refers to a refillable tape cassette (2,7) for accomodating a supply of printable tape. In order to avoid the need for different tape cassettes for different tape widths it is proposed that the tape cassette (2,7) is capable of selectively housing supplies of tapes of different widths. Alternatively or additionally, the tape cassette (2,7) can have a housing comprising a base (40) on which said tape supply can be releasably fixed, and a lid (42) fixed to said base (40), wherein the lid (42) is pivotally mounted to said base by means of a hinge (46). Further, proposals are made to hold the windings of refill tape units (30) together by means of a strip (60) of adhesive or wax on the axial ends of the units, or by scuffing the backing layer (9) of an image receiving tape (4) which is broader than the image receiving layer.
