摘要： A double-acting jar compounder is disclosed having a first end and a second end, and comprising an outer housing, an upper mandrel, and a lower mandrel. The upper mandrel defines the first end. The upper mandrel is at least partially disposed telescopically within the outer housing to define an uphole fluid chamber between the upper mandrel and the outer housing, the upper mandrel defining the second end. The lower mandrel is at least partially disposed telescopically within the outer housing to define a downhole fluid chamber between the lower mandrel and the outer housing. The uphole fluid chamber and the downhole fluid chamber each contain fluid, have a variable stroke-dependent volume, and are sealed at an uphole end and a downhole end. The upper mandrel has a first shoulder engagable with and facing a second shoulder of the lower mandrel to move the lower mandrel during at least a portion of a downjar or upjar stroke.

摘要： Non-prescription eyeglasses are disclosed. The eyeglasses include lenses having a region having increased convexity and magnification. The region is preferably centered below a horizontal on the lenses. Thus, a wedge shape is created. The thicker portion of the wedge is oriented toward the upper and inner side of the lenses, thus allowing the user to view close objects with decreased strain on the eyes. The method of providing non-prescription glasses having the features and advantages of the present invention without the need for a diagnosis or prescription is also disclosed.

摘要： A jar enhancer including a housing in which is telescopically mounted a mandrel, with the mandrel rotationally locked within the housing, and the housing and mandrel being spaced apart by an amount R at one location between them to form a chamber of width R. The upper end of the chamber is closed by a face, at least part of which is a shoulder extending inward from the housing, and the lower end of the chamber is closed by a face, at least part of which is a shoulder extending from the mandrel. The housing is sealed to the mandrel above and below the chamber and a port is provided for filling the chamber with compressible fluid. At least one of the shoulders has width W less than R, such that only a part of one of the faces bounding the chamber moves upon relative movement of the mandrel in relation to the housing. A second chamber of like design is provided in parallel with the first chamber to make a dual chamber, and in a still further jar enhancer, the dual chamber design has metallic springs rather than compressible fluid in the chambers and the shoulders need not occupy a portion of the end faces of the chamber.

摘要： A double-acting compounder is disclosed, comprising: an outer housing; an inner mandrel at least partially disposed telescopically within the outer housing to define a fluid chamber between the inner mandrel and the outer housing, the fluid chamber containing fluid and being sealed at an uphole end and a downhole end; an equalizer between the fluid chamber and an exterior of the outer housing for equalizing pressure; a movable seal assembly disposed within the fluid chamber and having a first end that defines the uphole end or the downhole end of the fluid chamber; the inner mandrel having an outer shoulder for contacting a second end of the movable seal assembly to move the movable seal assembly with the inner mandrel when the inner mandrel moves in a first direction relative to the outer housing to compresses fluid within the fluid chamber; and the outer housing having an inner shoulder for contacting the second end of the movable seal assembly to prevent the movable seal assembly from moving with the inner mandrel when the inner mandrel moves in a second direction relative to the outer housing to compresses fluid within the fluid chamber. The equalizer may comprise an equalization piston, and the double-acting compounder may comprise a restrictor for restricting initial movement of the movable seal assembly from both the inner shoulder and the outer shoulder due to hydrostatic pressure when the double-acting compounder is in a neutral position. The restrictor keeps the movable seal assembly from moving first and allows the equalizer piston to move and establish hydrostatic pressure in the fluid chamber. Thus, the movable seal assembly is kept in a neutral position and full stroke up and down is preserved, making the tool more efficient relative to a compounder without such an equalizer.
