Abstract
Abstract A process for the repair of worn ball and socket joints, journal bearings, and the like, in which the bearing parts are prepositioned in operative relationship and, in the case of ball joints, at an extreme of the range of movement in the direction of separation of the parts, lubricating the joint if dry, and then injecting through the greasing orifice, or through an opening at the end of the bearing, a bearing composition comprising a hardenable resin in fluid form, the viscosity of which is at least slightly greater than that of bearing grease, and which on hardening has an impact hardness of the order of not less than about 500 p.s.i.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
43 words
injecting into the space between the ball and the housing a plastic, hardenable bearing composition having initial viscosity of not less than about that of bearing grease; and displaying impact strength sufficient to withstand significant permanent deformation under conditions of use after hardening;
Claim 2
Dependent Claim
54 words
injecting into the space between the said ball or shaft portion of the bearing and the outer retainer portion of the bearing a plastic hardenable bearing composition having initial viscosity not less than about that of bearing grease; and display impact strength sufficient to withstand significant permanent deformation under conditions of use after hardening;
Claim 3
Dependent Claim
37 words
A process according to claim 1, in which the bearing is a journal type bearing, and in which the shaft is centered inside the outer retainer portion of the bearing before the injection of the bearing composition.
Claim 4
Dependent Claim
42 words
injecting into the space between the ball and the housing a plastic, hardenable bearing composition having initial viscosity not less than about that of bearing grease; and displaying impact strength sufficient to withstand significant permanent deformation under conditions of use after hardening;
Claim 5
Dependent Claim
54 words
injecting into the space between the said ball or shaft portion of the bearing and the outer retainer portion of the bearing a plastic, hardenable bearing composition having initial viscosity not less than about that of bearing grease; and displaying impact strength significant to withstand significant permanent deformation under conditions of use after hardening;
Claim 6
Dependent Claim
27 words
continuing injection of the said bearing composition until grease has been displaced from the bearing and the space between the parts thereof has been substantially filled; and
Claim 7
Dependent Claim
31 words
continuing injection of the said bearing composition until grease and loose bearing fragments have been displaced from the bearing and the space between the parts thereof has been substantially filled; and
Claim 8
Dependent Claim
22 words
A process for repair of worn, previously lubricated ball-joint bearings without removal of worn bearing material therefrom, which comprises the steps of:
Claim 9
Dependent Claim
31 words
continuing injection of the said bearing composition until grease and loose bearing fragments have been displaced from the bearing and the space between the parts thereof has been substantially filled; and
Claim 10
Dependent Claim
27 words
continuing injection of the said bearing composition until grease has been displaced from the bearing and the space between the parts thereof has been substantially filled; and
Claim 11
Dependent Claim
24 words
causing the said bearing composition to harden wherein said hardened bearing composition forms the surface against which the ball portion of the bearing wears.
Claim 12
Dependent Claim
26 words
causing the said bearing composition to harden wherein said hardened bearing composition forms the surface against which the ball or shaft portion of the bearing wears.
Claim 13
Dependent Claim
24 words
causing the said bearing composition to harden wherein said hardened bearing composition forms the surface against which the ball portion of the bearing wears.
Claim 14
Dependent Claim
22 words
A process according to claim 3, in which the bearing is lubricated with bearing grease prior to injection of plastic bearing material.
Claim 15
Dependent Claim
26 words
causing the said bearing composition to harden wherein said hardened bearing composition forms the surface against which the ball or shaft portion of the bearing wears.
Claim 16
Dependent Claim
21 words
A proCess according to claim 3, in which spring loading of said joint is increased by injection of said bearing composition.
Claim 17
Dependent Claim
28 words
A process for removing play and extending the useful life of ball-joint or journal type bearings without removal of original bearing material therefrom, which comprises the steps of:
Claim 18
Dependent Claim
37 words
A process according to claim 6, in which the bearing is a journal type bearing, and in which the shaft is centered inside the outer retainer portion of the bearing before the injection of the bearing composition.
Claim 19
Dependent Claim
28 words
A process for removing play and extending the useful life of a ball-joint journal type bearing without removal of original bearing material therefrom, which comprises the steps of:
