  • Patent number: 11213908
    Abstract: The wire feeding device that feeds welding wire W from the wire source to the welding torch is disposed between the wire source and the welding torch and is configured to temporarily accommodate the welding wire W fed from the wire source and to feed the accommodated welding wire W to the welding torch. In the case where feeding of welding wire W is abnormally stopped, if the acceptance unit accepts instructions for increasing or decreasing, the wire feeding device controls the speed of feeding welding wire W fed by the first feeding part or the second feeding part so that a difference is generated in the feeding speed of the first feeding part and the second feeding part and the accommodated amount of welding wire W is in a range from the lower limit of normal to an upper limit of normal.

  • Patent number: 4903398
    Abstract: An apparatus for fitting proper sizes of balance weights to the inner and outer rims of a wheel at proper positions. The apparatus includes a wheel balance measuring station and a balance weight fitting station arranged side by side. In the balance weight measuring station, the wheel is measured to detect unbalance of the wheel so as to determine sizes of balance weights to be fitted to the rims and positions at which the balance weights are fitted. According to the determination, weight size signals and position signals are provided and sent to the balance weight fitting station.

  • Patent number: 4386904
    Abstract: In order to produce vividly colored flames, instead of conventional primary combustion agents, such as paraffin and stearic acid, which produce a yellowish orange color by themselves, the primary combustion materials are used which form a colorless flame such as ethyl carbamate (urethane), dimethyl oxalate, and/or trioxane; in addition, an oxidation accelerator catalyst is absorbed on the cotton combustion wick, to result in a candle that itself burns with a strictly colorless flame. A coloring wick is separately fabricated containing a color-forming compound as well as oxidation accelerating catalyst and preferably may be coated with resin on its surface. The coloring wick is then placed adjacent the combustion wick, and a candle is formed using the aforementioned primary combustion material. One or several coloring wicks may be embedded parallel to the combustion wick or may be embedded coiled around the combustion wick.
