Abstract: Guide ring apparatus includes a shaft configured for insertion into a bore and annular bearing means disposed on the shaft for engaging the interior surface of the bore along with an annular spring having a preselected force-deflection characteristics in operative relationship with the bearing for causing the annular bearing means as well as the shaft to float within the bore. This particular bearing and spring arrangement accommodates for variations in the bore and shaft due to manufacturing tolerances, wear and other eccentricities of the shaft and bore.

Abstract: A radially resilient canted coiled springs includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and a leading portion. The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and a normal line. Specific resilient performance, or load-deflection characteristics of the radially resilient canted coiled springs is determined by controlling a turn angle of the coil spring.

Abstract: A cartridge bearing assembly includes a non-resilient tubular bearing element and a spring for causing the tubular bearing element to float with a shaft therethrough within a surrounding housing. Because loading between the bearing element and the shaft is eliminated, very close tolerances can be held therebetween and wear between the bearing and the shaft therethrough is substantially reduced. Seals may be incorporated into the bearing member in applications where a pressure drop is desired across the bearing shaft interface.

Abstract: A garter-type axially resilient coil spring includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and leading portion. The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and the normal line. Specific resilient performance, or load-deflection characteristics, of the spring is obtained by controlling the back angle. At selected back angles, the leading portion may be disposed at front angles beyond the range heretofore thought possible.

The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and a normal line. Specific resilient performance, or load-characteristics, of the springs are obtained by controlling a turn angle of the coil spring. At selected turn angles, springs exhibit a resilient working area bounded by steep load-deflection characteristics.

Abstract: The rotary/reciprocating seal apparatus includes a resilient ring member with a circumferential groove therein having a surface of revolution disposed at an angle with the axis of the ring member. The resilient ring member includes an axial opening thereinside for accepting and enabling the shaft to be rotated and/or reciprocated therein. The cylindrical housing is provided which includes an axial opening thereinside to accommodate the ring member and includes a groove on an inside surface of the cylindrical housing with a second surface of revolution disposed at an angle with an axis of the cylindrical housing. Spring means are provided in both the ring member and the cylindrical housing grooves for forcing the first and second surfaces of revolution away from one another in order to cause axial loading between the ring member and the cylindrical housing.

Abstract: A latching and sealing device suitable for use as a cover seal for a plunger or piston in a syringe or plunger pump includes a cylindrical seal member having a body portion and lip-and-latch means for both sealably engaging a surrounding surface and latching to the piston. A spring disposed in between the lip-and-latch means and the piston provide a constant sealing pressure while allowing the piston and seal member to be moved within a bore. Sealing between the lip-and-latch means and the bore is enhanced by use of a berm and notches radially aligned with the biasing spring.

Abstract: The loading and locking mechanism includes a first cylindrical member with means defining a circumferential groove therein having a first surface of revolution disposed at an angle with the axis of the first cylindrical member. Cooperating with the first cylindrical member is a second cylindrical member having an axial opening sized to accommodate the first cylindrical member and an inside surface groove having a second surface of revolution disposed at an angle with the axis of the second cylindrical member. A continuous ellipsoidal spring having canted coils is disposed in both first and second cylindrical member grooves for forcing the first and second surfaces of revolution away from one another to cause axial loading between the first and second cylindrical members. Additional locking surfaces may be provided each of the first and second grooves which are disposed generally perpendicular to the first and second cylindrical member axis.

Abstract: The present invention includes a method for the manufacture of a bearing seal which includes providing a polymer and/or a filler coated with a polymer and thereafter heating the coated filler to bond the copolymer to the filler. Following cooling of the coated filler, it is pulverized and added to granular polytetrafluoroethylene. This admixture is then mixed to obtain a uniform blend and thereafter shaped by compacting and heating into a preselected form. Fillers suitable for the present invention may be carbon, metal, glass, carbide, disulfide, polymeric, polyester fluoride and ceramic fibers.

Abstract: A coiled spring includes a plurality of coils with each of the coils being interconnected with one another in a spaced-apart relationship and disposed in a preselected acute angle with the centerline of the coil spring for causing the coil spring to exert a constant force in a loading direction approximately normal to the centerline of the coiled spring in response to a deflection of the coil spring along the loading direction. When placed in an operative relationship with a sealing material, the resulting coil spring seal enables positive sealing between cooperating parts to prevent passage of fluid therepast, despite small changes in the spacing between the parts which may change due to eccentricity and part dimension, wear, temperature, or pressure effects.
