Title: Manufacture of iron powder from scrap produced by polishing steel material
Inventor: MATSUI KOUTAROU
IPC: C22B7/00
Filed: 1984-02-25
Abstract: PURPOSE:To separate and recover effectively iron powder from scraps produced by polishing a steel material by drying and heating the scraps, feeding them to a rotating cylinder, and carrying out stirring and grinding with steel balls so as to separate steel powder from nonmagnetic abrasive grains. CONSTITUTION:Scraps produced by polishing a steel material are sent to a shoot plate 2 with a bucket conveyor 1 and heated in a heating furnace 3 to burn impurites. The scraps are fed to a rotating cylinder 7 by applying vibration with an electromagnetic vibrator 4. The fed scraps are stirred and ground by mixing with steel or ceramic balls 8 in each box 6 of the cylinder 7, and they are successively sent to the lower end of the cylinder 7. During this time, fine powder is sucked through circulating holes 10 in a pipe shaft 9 with a suction pump 11. Steel powder in the ground scraps is separated from nonmagnetic abrasive grains with an electromagnetic rotor 13, the powder is dropped into a storage box 14, and the abrasive grains are dropped into a storage box 15.

Title: Transporting truck for parking lot
Inventor: YANAI MASAHIRO
IPC: E04H6/18
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To realize a transporting truck by which vibration can be reduced while it tavels by connecting a frame supporting a loading part on which articles to be transported is mounted and bearing parts supporting the axles of wheels through an elastic member. SOLUTION: A frame 2 receiving load such as articles to be transported and bearing parts 6 supporting axles 9 are connected to each other through air springs 10 as elastic members. Hence, vibration caused by rotation of wheels 5 and vibration generated when the wheels 5 get over joints of guard rails 56 are absorbed by the air springs 10 functioning as suspensions. In this way, since vibration generated when the transporting truck travels is reduced, as a result, vibration propagated to cars and frame members of a multi-story parking lot to be transported provided in the transporting truck can be reduced.
