Filed:

Oct 31, 1983

Appl. No.:

6/547310

Inventors:

Charles W. Pierson - Rochester NY
Frederick F. Tone - Holley NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B65H 7528

US Classification:

242 74

Abstract:

A film magazine is disclosed which comprises a light-tight casing and a spool rotatable therein. A leader has one end attached to the spool and extends outside the casing for splicing to light-sensitive film. The splice is retracted into the casing during spooling operations, and means are provided to prevent the splice between the film and the leader from being pulled from the magazine.

Abstract:

A water filter cartridge includes a reverse osmosis membrane permeator spirally wound on a central winding tube and surrounded by an impermeable barrier layer which is, in turn, surrounded by a spirally wound prefilter. A post-filter is placed centrally within the winding tube. The cartridge is designed for functional installation in a housing tube fastened and sealed to a valve plate at a first end and closed by a removable end cap at the other, second end. Feed water enters the cartridge through an inlet port in the valve plate at the first end at an outer radius to pass lengthwise in prefilter. Prefiltered water returns from the second end lengthwise through the reverse osmosis permeator to a waste-water outlet port in the valve plate at an intermediate radius. Product water which has permeated through the membrane flows inwardly through holes in the winding tube and into a clearance space surrounding the central post-filter. After traveling to the second end in the clearance space, the permeate flows through the length of the post-filter to a purified-water outlet port at an inner radius in the valve plate.

US Classification:

Abstract:

"A water purification system has a reverse osmosis filtration unit which receives feed water from a feed water valve and separates it into product water and waste water. A reservoir has a movable separator dividing it into a product water chamber for receiving the product water and a control water chamber. The product water is delivered to an outlet connection from the product water chamber or directly from the filtration unit. A regulator is connected to the waste water outlet port of the filtration unit, the control water port of the reservoir, and a drain line. The regulator has a first valve for providing waste water from the filtration unit to the control water port of the reservoir for urging the separator toward the product water chamber. The regulator has a second valve that can rapidly drain water from the control water chamber of the reservoir and rapidly reduce pressure in the control water chamber, thus facilitating the refilling of the product water chamber. A relief valve downstream of the second valve maintains a low pressure in the system to avoid undesirable cycling of the system between high pressure and low pressure. ".

US Classification:

Abstract:

A photographic film unit with lateral and transverse edges having a pair of sheets connected in superposition with a photosensitive layer located between the sheets. A container carrying a quantity of fluent processing composition is arranged to provide for the discharge of the composition to between the sheets. The improvement comprises an integral intermediate sheet disposed between the pair of sheets and coupled to both of them at the lateral marginal portions thereof and separating such lateral marginal portions of the sheets by a predetermined amount. A portion of the intermediate sheet extends from between the pair of sheets at one end thereof and is secured transversely to one of the sheets at that end and is folded away from that sheet over itself within the compass of that sheet to define a compartment for fluent processing composition. The intermediate sheet has a centrally disposed exposure aperture and lateral edges which are in register with the lateral edges of the other sheets. The outer portions of the lateral edges of the intermediate sheet have a greater thickness than does the boundary of the aperture.
