Abstract: A relativity controller is a scroll bar/window combination that provides a way to see data in relation to both the context of its wholeness and the salience of its contents. To accomplish this, the linear density or other appearance of the scroll bar (acting as a ruler or scale) varies with the density of the document salience (as indicated by different kinds of annotations or marks). It also provides a way to zoom between perspectives. This is usable on many different data types: including sound, video, graphics, calendars and word processors.

Abstract: A multiple wall tank for the storage of liquids is manufactured from a rigid, single wall inner tank having at least one aperture by applying an outer sheath over the inner tank, removing a portion of the tank surrounding the aperture, applying a layer of a synthetic resin material to the inner tank exterior surface surrounding the aperture, providing a spacing means to provide for substantially free passage of liquids between a substantial portion of the inner tank and the outer sheath and bonding a portion of the outer sheath to the synthetic resin layer surrounding the aperture to form a substantially liquid impervious seal around the aperture.

Abstract: A double wall tank for the storage of liquids is manufactured from a rigid, inner tank by helically extruding a synthetic resin outer sheath over the sidewall portion inner tank while preventing bonding between the extruded outer sheath and the inner tank, with outer end portions that are sealingly bonded to the outer sheath sidewall portion.

Abstract: A storage tank and method for making it is disclosed in which a first tank portion having a cylindrical sidewall is formed by helically extruding a plurality of partially overlapping layers of synthetic resin on a portion of a cylindrical form, with an end portion being formed and sealingly affixed to the sidewall portion, with the cylindrical form being removed from within the first tank portion, and then any remaining open cylindrical end being closed to form a closed cylindrical tank.

Abstract: A double wall tank for the storage of liquids is disclosed, comprising a rigid inner tank having an aperture formed through a sidewall of the inner tank, and an outer sheath of synthetic resin material having an opening generally overlying the inner tank aperture and a generally annular flange member attached to the inner tank and extending over a portion of the outer sheath adjacent to and surrounding the outer sheath opening to urge that outer sheath portion toward the inner tank sidewall to form a substantially liquid impervious seal between the outer sheath and the inner tank surrounding and proximal to the inner tank aperture. A generally cylindrical passage member is attached to the inner tank adjacent the aperture and extending through the annular flange member to provide a substantially liquid-tight passage into the inner tank through the aperture and the opening in the outer end of the cylindrical passage member.

Abstract: A multiple wall tank for the storage of liquids is manufactured from a rigid inner tank having at least one aperture by applying a layer of a synthetic resin material to the inner tank exterior surface around the aperture, providing a spacing means to provide for substantially free passage of liquids along at least a portion of the inner tank, applying over the layer of synthetic resin and the inner tank an outer sheath of a thermoplastic synthetic resin material, and bonding the outer sheath to the resin material layer surrounding and proximal to the aperture to form a substantially liquid-impervious seal around the aperture.

Abstract: The present invention is directed to an apparatus for elevating a cover for a meter enclosure that may be buried in the ground. The apparatus includes first and second coaxial, right circular cylinders, the first cylinder including a protruding member extending from its outer surface, with the second cylinder having a diameter greater than or equal to the diameter of the first cylinder and including a pair of spaced apart notches formed in the inner sidewall thereof. The first cylinder may be attached to the meter box, with the protruding member generally securing the apparatus to the enclosure and the enclosure cover may then be attached to the top of the second cylinder.

Abstract: A nozzle for a container including an internal ball check valve along with an o-ring sealing structure and angled insertion limitation stops to cooperate with a receptacle to permit the insertion of the nozzle and container only a predetermined distance, while providing for such insertion to effect an opening of the ball check valve, and appropriate sealing o-rings are provided to prevent leakage of the liquid past the nozzle.

Abstract: The hand splint apparatus of the present invention is directed to a hand splint apparatus and method of attaching a hand splint apparatus to a patient's forearm that includes a forearm support, an elongated and inelastically deformable connector having an axis extending between a first and second end thereof, with the connector first end attached to the forearm support and with the connector second end attached to a hand piece proximal to a first end of the hand piece, such that the connector is adjustable in a plurality of directions transverse to the connector axis for orienting the hand piece to a desired position with respect to the forearm support.

Abstract: A liquid phase is placed into contact with a steam or gaseous phase to cause a reaction, heat and/or matter transfer, where the contact of the phases occurs within at least one annular chamber formed of two or more concentric and substantially coaxial elongated cylindrical members. The gaseous phase and the liquid phase typically enter the chamber at opposite ends cylindrically rotating in the same direction and in countercurrent, with the gaseous phase and at least a substantial portion of the product formed by the contact between the phases exiting the at one end of the apparatus and the residual liquid phase exiting at the other end.
