A metal mold is disposed adjacent to the outer circumference of a base ring, and has a molding face in the inner circumference and a plurality of grooves for forming beads on the molding face along the circumferential direction. A coil for electromagnetic forming is disposed adjacent to the inner circumference of the base ring. When a momentary large current is applied to the coil in this arrangement, the diameter of the base ring is expanded by pressing the base ring toward the molding face of the metal mold such that the base ring is molded into a shape corresponding to the molding face by electromagnetic forming. Improvements such as a metal mold capable of degassing, a separable metal mold, roll-correcting after electromagnetic forming, application of momentary large current over several times, a metal mold with a cutting blade, use of a base ring with a large number of holes, and a metal mold with positioning means are then added. With these improvements, a highly accurate cylindrical ring with beads can be produced at low cost and with high productivity.

A magnetic metal removing device for color sorting apparatus includes a hollow feeding roll. Within a hollow portion of the feeding roll, a magnet is arranged such that it closely opposes to a part of an inner surface of the hollow feeding roll to form a magnetic force active surface on the corresponding outer surface of the feeding roll. Magnetic metal mixed in raw granular objects is attracted on the magnetic force active surface. The magnetic forced active surface changes to a magnetic force inactive surface as the feeding roll rotates. The magnetic metal caught on the feeding roll is released from the magnetic forced inactive surface and colleted by a collecting device.

A color sorting machine sorts particles of different colors from raw material such as cereal grains or the like. The machine has a down chute descending towards a front side of the machine for letting raw material particles flow down linearly, a photoelectric detection device which subjects the raw material particles jumped out of the down chute to light and discriminates different-color particles in accordance with difference in reflected light, and a nozzle device which injects air to and blows off the different-color particles. The injection nozzle device is situated on the rear side of the machine with respect to a coming-down locus of raw material particles from the down chute and close to the coming-down locus. The sorting machine further comprises a dust collecting device which is situated on the front side of the machine with respect to the coming-down locus of the raw material. The dust collecting device has a dust collection opening which is substantially opposite to the injection nozzle device with the coming-down locus interposed therebetween, sucks in and discharges dust scattered from the raw material. The color sorting machine is highly precise in sorting different-color particles and facilitates cleaning of the dust collecting device.

A vibration-damping section with sound absorbing material includes a sound proof panel, sound absorbing material fixed on one surface thereof and vibration damping material stuck on the top surface or the bottom surface of the sound proof panel one surface of the sound absorbing material which is the opposite side of the sound proof panel can be covered with a porous panel, if necessary, and moreover a joint is provided for hanging and connecting sections for closely connecting themselves one another in a width direction. Since the vibration-damping section with sound absorbing material according to the present invention has above described structure, in particular, it can be fixed on the bottom surface of an elevated bridge and has a sound insulating effect of the radiated noise which are caused by the elevated bridge structure and a sound absorbing effect of the reflected noise and moreover has a vibration damping effect of decreasing occurrence of the secondary noise by reducing the vibration of the sound absorbing panel.
