What's the difference between dispart and trunnion?

Dispart

Definition:

(v. t.) To part asunder; to divide; to separate; to sever; to rend; to rive or split; as, disparted air; disparted towers.
(v. i.) To separate, to open; to cleave.
(n.) The difference between the thickness of the metal at the mouth and at the breech of a piece of ordnance.
(n.) A piece of metal placed on the muzzle, or near the trunnions, on the top of a piece of ordnance, to make the line of sight parallel to the axis of the bore; -- called also dispart sight, and muzzle sight.
(v. t.) To make allowance for the dispart in (a gun), when taking aim.
(v. t.) To furnish with a dispart sight.

Example Sentences:

(1) A quantitative estimate of the dispartate affinities of Mg(II) to ATP bound at the two sites on the enzyme was made on the basis of computer simulation of changes in the line shape of beta-P (ATP) resonance and of changes in 31P chemical shift of the corresponding gamma-P (ATP) in the E.ATP complex with increasing [Mg(II)].
(2) In separate experiments, subfraction differences in oxidation rates as assessed by TBARS formation were verified by the finding of similarly dispartate changes in fluorescence intensity and anionic electrophoretic mobility.

Definition:

(n.) A cylindrical projection on each side of a piece, whether gun, mortar, or howitzer, serving to support it on the cheeks of the carriage. See Illust. of Cannon.
(n.) A gudgeon on each side of an oscillating steam cylinder, to support it. It is usually tubular, to convey steam.

Example Sentences:

(1) A follow-up study of 61 hips replaced by the trunnion bearing prosthesis was performed 2.5 years postoperatively.
(2) In three prostheses the polyacetal sleeve of the trunnion was so worn that the head bore directly on the stem.
(3) The biomechanics are presented of a bushing principle forming the basis for a trunnion bearing prosthesis in total hip replacement.
(4) A Christiansen trunnion-bearing hip prosthesis (Christiansen, 1969 and 1974) was used in all patients except one.
(5) This prosthesis was designed with a socket and a trunnion sleeve made of polyoxymethylene or Delrin.
(6) The femoral stem is equipped with a trunnion on to which a cylindrical plastic sleeve is applied.
(7) On flexion-extension this remains stationary in the acetabular cup and motion occurs between the trunnion and the cylindrical sleeve.
(8) We report upon 167 fractures of the medial femoral neck (166 patients aged 82 years on average) that were treated by hemialloarthroplasty (trunnion hip prosthesis Allo-Pro).
(9) The trunnion bearing may thus have spared the hip joint from stress during the first years of use.
(10) In this prosthesis an articular connection, or trunnion bearing, is introduced between the head and stem components in order to reduce friction at the acetabular joint.
(11) Acetabular protrusion was found in 14 cases, indicating that there are frictional forces working at the hip joint, also with the trunnion bearing system.
