Title: Edger roll for rolling h-beam
Inventor: NAKAGAWA YOSHIHIRO
IPC: B21B27/02
Filed: 1980-08-08
Abstract: PURPOSE:To provide good abrasion resistance and surface roughening resistance to the barrel parts of rolls by providing tapered roll surfaces to both ends of the barrel prts of the rolls for rolling edge parts and making the large diameter side thereof largest in outside diameter. CONSTITUTION:In molds by a metallic mold 20 and sand mold 21, 22, the metallic mold 20 for the barrel part is satisfactory if it has an inside diameter corresponding to the maximum diameter D3 of the roll barrel parts 19 in rolling rolls 14, 15, and the inside diameter of the metallic mold fairly smaller than that corresponding to the maximum diameter of the barrel part in conventional rolls is sufficient. Hence, the distance l2 from the inside surface of the mold 20 up to the roll barrel part 19 to be actually rolled is made extremely short, and in the case of casting said part by pouring molten metal, the rate of solidification of the molten metal during casting increases as well. Therefore, the casting structure in the barrel part 19 is dense, and the good structure of high hardness is easily obtained. Thereby, the quality of the rolls 14, 15 is improved, and the abrasion resistance and surface roughening resistance of roll surfaces 19b, 19b are improved.

Abstract: PURPOSE: To cause always sure type selection, by effecting the type selection process of each printing cycle when the drive motor of a printer has reached a constant speed.  
     CONSTITUTION: A power switch 1 is closed to supply electric power to an electronic circuit etc. as shown at 2, 7. A printing instruction 3 is then applied to supply a voltage 4 to a motor. As a result, a current 5 flows between the terminals of the motor to rotate it. When the rotational frequency 6 of the motor has reached a constant level in a time of 100m sec or more, the all-digit true-up and return of type wheels is completed and a waiting period begins. At that time, a printing OK signal In is produced by a printer to inform that information to be printed can be entered into the printer and that a timing signal T is entered from the printer. After that, the type wheel starts rotating forward and signals T 0 WT 12  are applied to select a type to perform printing 8 and then perform paper feed operation 9. During that time, a timing signal T 13  is produced to cut off the current 5 and cause stoppage at the initial part of a type wheel return period.
