Abstract: Flexible remote controls of the type using ball bearings along their length are improved by externally imparting reversing bends along their length which bends are imparted by two semi-circular sleeves, having mirror image mating faces containing an interior contour of reversing radii, having arcs being the minimum bend radius of the partial flexible ball bearing remote control to which it is applied, which come tangent at the center and run out an equal depth from the centerline and repeat throughout the length of the flexible ball bearing remote control.

Abstract: A flexure-limiting tubular ball and socket universal joint device protectively supports and guides the inner or center cable of a coaxial push-pull cable assembly while providing a seal effective to exclude dirt and moisture in the variously deflected positions of the inner member and its load-connected extension rod fitting. The cable inner member extension rod fitting passes through a support tube and a sliding seal therein, the support tube having at one end a hollow ball-shaped element that snaps into a mating socket element on a socket tube of resilient plastic material. The socket tube with the ball element retained in the socket element is then inserted longitudinally into a receptacle formed in a tubular terminal member on the outer cable.

Abstract: Self-centering action in a push-pull coaxial cable is provided by an encapsulated spring loaded device formed to be mounted as a collar encircling the end assembly of the cable by threading its inner tubular member on the conventional cable's load actuation rod and by interconnecting its outer tubular member with the cable mounting fixture or with the latter's anchor support. Occupying only a small annular space around the cable's end assembly without projecting lengthwise beyond it, the device responds to relative displacement of the cable members in either direction from a neutral position by spring reaction force that increases with displacement.
