Abstract: In accordance with the present invention, there is provided a filter assembly having an improved system for selectively jacking a filter canister into and out of engagement with a filter head. A threaded jackscrew is mated to a threaded portion of the filter head and rotatably mounted to the filter canister, but longitudinally confined near the canister top. The assembly accommodates a second class lever whose fulcrum end is received in a recess in the filter head. The jackscrew includes a plurality of circumferentially spaced lugs around the jackscrew perimeter against which the central portion of the lever can successively act. The manual application of force to the free end of the lever creates a mechanical advantage at the jackscrew lugs such that a torque sufficient to free and turn the jackscrew can be generated. Repeated pivoting of the lever against the lugs of the jackscrew in a ratchet-like manner unscrews the jackscrew, and the captive canister, from the filter head.

Abstract: An annular drip collector is shaped and dimensioned to slidably sleeve onto the cylindrical wall of an oil filled filter cartridge, in need of replacement, while the cartridge is projecting from an engine and attached by its threaded open end. The large diameter wall of the collector forms a truncated conical trough with the adjacent cylindrical portion of the cartridge wall proximate its open end to collect oil spillage. The integral, smaller diameter cylindrical wall, or skirt, of the collector toward the closed end of the cartridge is substantially equal in inside diameter to the outside diameter of the cartridge. At least one integral, inward projecting, annular rib, tooth or flange in the lower cylindrical wall, seals the collector against the cartridge by reason of the flexible, resilient, polyethylene plastic of the collector. The outwardly flared, truncated conical, collector will nest with other collectors for shipment.

Inlet and outlet openings are disposed at the open and remaining end, respectively, of the tank with the inlet opening being in the side wall of the tank, near such open end, so as not to interfere with opening and closing of the cover. Inner and outer annuli are fixed to the tank side wall and face radially into the tank, with the inlet opening interposed axially therebetween. A spacer insertable into the tank comprises an annular inner disk pressable toward the inner annulus for gripping therebetween an inner resilient seal which in turn engages the adjacent edges of the filter basket and filter liner to prevent leakage therearound between the unfiltered and filtered liquid zones.

Abstract: A machine for separating an oil film from a supporting liquid elevates the oil from its original position with an endless belt, and then transfers the oil from the belt to a rotating disc from which it is wiped into a drainage trough. The belt system is driven from the disc, and is constructed as an attachment to a self-contained disc machine capable of functioning without the belt system when the disc can intersect the surface of the liquid. The unit is thus adaptable to installations where the liquid level is far below the rim of the accumulating tank where the machine is mounted, and where there is substantial variation in the liquid level.

A coupling upstands from one end portion of the base unit and is attachable to a faucet for receiving a supply of water. An outlet is downwardly directed from the base unit to discharge water received through the coupling. Also disposed within the base unit is a valve that selectively permits the flow of water through the coupling and in discharge from the outlet. Upstanding from another portion of the base unit is an inverted cup-shaped cap. An input fluid channel within the base unit leads from the valve to the chamber defined by the cap, and the valve selectively permits the flow of water through the coupling into the input channel and from that into the chamber.

Abstract: A filter cartridge utilized in filtering dry cleaning fluid includes an annular, generally cylindrical outer member which carries a tubular, pleated paper filter and an annular, generally cylindrical inner member which carries a particulate sorbant mass therewithin. In conventional use, dry cleaning fluid is caused to flow radially inwardly through the filter cartridge, first passing through the pleated paper filter and then through the sorbant mass. The fluid exits through a longitudinal passageway extending axially through the cartridge. After the filter cartridge has been spent, the inner member may be slidably removed from the outer member in order that the considerable weight of the spent cartridge may be removed from the filter tank in two separate operations.

Abstract: A pressure filtration cell includes a reservoir for liquid to be filtered, a filter at the bottom of the reservoir, and a manually actuable pump for supplying compressed air. The pump is detachable from the reservoir. The air is introduced near the bottom of the reservoir closely adjacent the filter so as to create turbulence in the liquid and across the filter. The turbulence is of a pulsating nature due to the intermittent operation of the pump. Thus, the pump is easily portable for use anywhere and creates a "dynamic" filtration process even without a mechanical stirrer. If used in a laboratory, the cell can be provided with a rotary, magnetically operated stirrer mounted on a relatively short axle.

Abstract: A tea strainer for use in straining tea while it is poured into a teacup, which may be sitting in a saucer. A bowl-like sieve member, provided with projections for engaging the lip of the cup, also has a handle which is made in two parts connected together by a hinge. The hinge is so located that the outer portion of the handle can swing downwardly into contact with the table on which the cup rests. The inner handle portion is sufficiently long so that it lies normally beyond the diameter of the saucer when the cup is sitting in the saucer. The hinge is stiff enough so that it ordinarily must be manually and purposely moved from one position to another. When held in the hand, the tea strainer functions as a normal tea strainer with a stiff handle, but when placed in the cup and the handle moved about the hinge and put in contact with the table, it becomes self-supporting.
