Abstract: To manufacture a steering wheel rim, a sleeve 21 is formed by a braiding machine 12 by interlacing and braiding unidirectional fibers 10. A coil-shaped lightweight core 9 is then inserted by a covering apparatus 14 into the braided sleeve, and core rings are cut out from the coil. The ends of the cut rings are butted to form the rims, and after being joined with a spoke 2 are placed in a mold 31, where an outer molded layer 11 is formed by injecting a thermosetting resin into the mold and heat curing it.

Abstract: In a steering wheel for an automobile or the like comprising a rim, a spoke and a boss, the rim comprises a core of lightweight material and a plastic layer reinforced with unidirectional reinforcing fiber and surrounding the core, and the spoke is formed from a metal and has one end secured to the boss which is also formed from a metal, while the other end of the spoke is secured to the rim by a plastic layer reinforced with unidirectional reinforcing fiber.

Abstract: An apparatus for deploying and taking up an oil fence comprises a floating framework having a substantially enclosed oil fence receiving space therein and one side partly cut away and, roll means disposed in front of the cut-away portion. The roll means can be driven to sinuously house the oil fence within the framework and to pay it out from the latter. Alternatively, a takeup shaft disposed in a box-shaped member with buoyant chambers and fenders may be driven to coil and uncoil the oil fence on and from it through one open side of the box-shaped member.This is a divisional of application Ser. No. 443,131, filed Feb. 15, 1974 now U.S. Pat. No. 3,971,220.

Abstract: An array of semicylindrical floats juxtaposed on one surface of a longitudinally elongated screen about each of spaced cross strips on the screen opposes a similar array disposed on the other surface of the screen and a chain-shaped sinker is disposed along one longitudinal edge of the screen. Also a floating framework is disclosed having one side partly cut away and roll means disposed in front of the cut-away portion. The roll means can be driven to sinuously house the oil fence within the framework and to pay it out from the latter. Alternatively, a takeup shaft disposed in a box-shaped member with buoyant chambers and fenders may be driven to coil and uncoil the oil fence on and from it through one open side of the box-shaped member.
