Abstract:
Filter pads, which are made inherently stable by binders and by removal of the binders can be converted in packings to be maintained under substantially constant surface pressure between rigid filter brackets, are produced first as molded bodies from a suspension of filter aids in liquid by depositing granular, fibrous, or fiber-containing filter aids or mixtures of those filter aids in a casting mold, there being used high rates of flow while avoiding turbulences, and adding binders to the suspension so that the molded body can be stabilized by activation of the binder while drying. It is possible in this process also to manufacture multi-layered filter pads, it having been surprisingly found in those multi-layered filter pads that the layer assembly is kept intact during the filtration even in the filter packing that no longer contains binders. The filter pads or the filter packings produced therefrom according to the invention can, when used, and after reflushing and regeneration operations, finally be utilized, after being replaced, as filter aids in the deposit filtration process.

1,273,251. Filters. CARBORUNDUM CO. 2 May, 1969, No. 22422/69. Heading BID. A sleeve-like filter element (16) of sheet material is constrained to pleated shape by having its ends clamped against outwardly extending cogs 22, 24 of a core 12 by respective segmented clamping rings 40, 42 which present inwardly extending cogs 52, 54, fitting between cogs 22, 24 (Fig. 1, not shown). The two ends of the core are joined by posts 38, and the rings 40, 42 may be similarly joined by ribs 44 or separate. Core and rings are moulded of polypropylene, and the segments of the rings in Fig. 3 are connected by integral, flexible straps 58. The rings open out (Fig. 5, not shown) to facilitate replacing the element (16), and their mating ends are secured by catch 78 or by an enclosing wire clamp (76) (Fig. 1, not shown). In Fig. 1, clamp (76) encircles axial extensions 52 of the ring, but in Fig. 10 (not shown) radial extensions support the clamp (76) around but clear of straps 58. Fig. 8 (not shown) illustrates non- integral straps (96), and in Figs. 7, 9 (not shown) ring segments are hinged together by pins (90) in slots (92). Figs. 11 to 13 (not shown) illustrate sealing the ends of the filter element between pairs of concentric gaskets or by integral rubber mouldings.
Abstract:
A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.
Abstract:
A removable closure assembly has a cap making a liquid-tight seal with a tri-clamp assembly to the open end of a filter assembly body. The closure assembly has a filter which fits within the filter body. To aid in separating the closure assembly from the body, the cap has an outwardly extending shaft fixed thereto. The shaft is terminated by a radially protruding stop block. A handle is slidable on the shaft and functions as a slide hammer weight with an end wall facing the cap through which the shaft extends. The handle is movable to strike the shaft stop block and apply a force to the stop block and shaft for separating the cap from the body. The stop block has axial channels allowing a clean out of place system to exchange cleaning fluid with an interior volume of the handle.
Abstract:
A filter receptacle assembly is described including a filter receptacle having a receptacle wall and a circular edge defining an opening for receiving a filter cartridge and a first interlock device coupled to the receptacle wall of the filter receptacle, wherein the first interlock device comprises a first actuator moveable between a first position and a second position and biased into the first position, wherein at least a portion of the first actuator protrudes from the receptacle wall in the first position, wherein the first interlock device is configured so that when a filter cartridge is inserted into the filter receptacle, the first actuator is moved by the filter cartridge from the first position to the second position and is held in the second position by the filter cartridge.
Abstract:
A filter element may include a tubular member, and tubular member may include a partition at least partially defining first and second chambers. The tubular member may further include an end portion at least partially defining an inlet port configured to provide flow communication into the first chamber, and at least partially defining an outlet port configured to provide flow communication from the second chamber. The tubular member may further include a cover portion at the end portion of the tubular member, with the cover portion extending from the partition. The cover portion may be configured to at least partially cover a longitudinal end of the second chamber. The filter element may further include a filter medium associated with at least one outlet aperture and the at least one inlet aperture of the tubular member.
Abstract:
A filter incorporating a vessel defining an interior space, the vessel having a ceiling and a floor; filter media contained within the interior space; a helically threaded port which opens the vessel's interior space at the ceiling; a turn plate having a an outer edge; a retainer ring and snap ridges combination which interconnects the turn plate and the vessel, positions the plate beneath the floor, and facilitates circumferential motion of the plate's outer edge; a turn handle connected operatively to the plate, the turn handle being adapted for impelling the turn plate's circumferential motion; and ratcheting hook and ridge combinations which further interconnect the turn plate and the vessel, the hooks and ridges being adapted for, upon turning of the handle, translating a limited screw tightening torque to the ceiling's helically threaded port.
Abstract:
A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.
Abstract:
Crankcase ventilation filter assemblies, components thereof, features thereof, and methods of assembly and use are described. An example assembly is characterized in which the assembly includes a housing having an access cover and a base, and a filter cartridge is configured to sealingly engage both the access cover and the base, in preferred manners
