Abstract:
The invention discloses a looper of the type in which the tension exerted to the strip is controlled in response to the output derived from sensor means attached to a rotatable looper arm for detecting the tension exerted to the strip.
Abstract:
A wire electrode for use in arc welding comprising a metal to be deposited on a substrate and further comprising a flux, said flux comprising: 1. A magnesium-aluminum alloy having an aluminum content of 20 to 80 percent, said alloy present in said flux in the amount of 5 to 35 percent by weight; 2. Calcium fluoride present in said flux in the amount of 30 to 80 percent based on the weight of said flux; 3. Hematite present in said flux in an amount of 3 to 30 percent by weight; 4. Silica and/or manganese in an amount less than 10 percent based on the weight of said flux; 5. Titanium in an amount less than 1.00 percent, based upon the weight of said flux; 6. Zirconium present in said flux from 0.005 to 0.200 weight percent, based on the weight of said flux; and 7. Boron in an amount less than 0.060 weight percent, based upon the weight of said flux.
Abstract:
A raw material distribution chute is rotated when inner and outer cylinders are rotated in unison, and is tilted when the inner or outer cylinder is vertically moved with respect to the outer or inner cylinder. The rotation and tilting of the distribution chute may be made simultaneously or individually so that the pattern of raw material distribution may be varied over a wide range.
Abstract:
A furnace wall is constructed with or includes coolers of the type comprising a main body made of cast iron or copper and a plurality of cooling tubes cast integral with the main body so that the furnace wall may be cooled by cooling water flowing through the cooling tubes. Water leakage problem may be overcome and the life of the furnace wall may be remarkably increased.
Abstract:
A trolley is provided in a set of two or more hoisting pulleys or sheaves on one side and another set of two or more hoisting pulleys or sheaves on the other side carried by a trolley frame which travels along a horizontal girder are so arranged as to mechanically move toward or away from each other, so that the loading and unloading of a cargo in a narrow space may be effected.
