摘要： A cable spacer for use between pairs of subconductors in overhead power transmission lines comprising a pair of similar lever arms, each lever arm having two semi-circular section grooves with a resilient lining, one groove being provided at either end of the lever arm, a pivotal connection between the lever arms arranged such that relative pivotal movement of the lever arms causes the grooves at the ends adjacent to the pivot to come together and form a first circular aperture for engaging a first subconductor and the grooves at the other end to form a second circular aperture for a second subconductor, and a fixing means for locking the arms in engagement with a pair of subconductors.

摘要： An enclosing means for lubricant for use in a pneumatic tire and wheel assembly to be located on or adjacent the interior surface of at least one lower sidewall region of the tire. The means comprises a closed annular pocket, at least one radially extending portion of a wall of which is constructed to be under greater stress than the remaining portions when the pocket is filled with lubricant and located in the tire. The greater stressed portion is located nearest to the interior surfaces of the tire when in use to urge the pocket towards the interior surface of the tire against counteracting centrifugal forces which tend to urge the pocket away from the surface. Also included is a tire and wheel assembly.

摘要： An apparatus for mounting and removing tires from wheel rims having at least three arms with means to engage the wheel rim for holding it. Each of the arms has one end pivotally secured to a circular plate and the center portion of each arm is slidably and pivotally mounted to another circular plate so that the free ends of the arms are radially movable when one plate is rotated in relation to the other. Braking means continuously engage one of the plates to insure relative rotation between the plates. The braking means move in a radial direction so that the braking surfaces will be self-cleaning.
