  • Patent number: 4098428
    Abstract: A horizontal-type tank for therein operating heated pitch impregnation of carbon electrode blanks, comprising a cylindrical body having an annular weir member disposed near its open end portion for preventing flowing out of an unused pitch portion, and a lid member releasably closing the opening of the body, which has a double wall structure providing between the outer and the inner walls a heated pitch jacket in liquid communication with the body, said inner wall having an outer edge portion protruding into the body beyond the location of the weir member. The body also has an annular coolant jacket disposed close to its flange surface portion against which an annular seal member provided to a flange portion of the lid abuts.

  • Patent number: 4087011
    Abstract: In order to improve mechanical and electric characteristics of carbon electrodes, they are impregnated with pitch. This impregnation operation can be accomplished at high efficiency by loading a plurality of electrodes on a specific pallet. However, when the carbon electrode-loaded pallet is dipped in an impregnation vessel, pitch adheres to the pallet, and if such pitch-adhering pallet loading fresh carbon electrodes thereon is introduced again into a pre-heating furnace prior to the impregnation operation, the pre-heating furnace is contaminated with pitch and there is a risk of a fire. In order to avoid this disadvantage, there is adopted a method in which different pallets are used for introducing carbon electrodes into the pre-heating furnace and for introducing them into the impregnation vessel, respectively. In this method, the operation of shifting carbon electrodes from one pallet to another pallet is necessary.

  • Patent number: 4049241
    Abstract: A motionless mixing device for mixing fluidic materials such as liquid, gas, wet and dry powders, etc. employing a generally horizontal cylindrical housing with an inlet at one end and an outlet at the opposite end. A plurality of spaced-apart mixing elements are positioned in the housing to form a mixing device, each of mixing elements being inclined transversely of the longitudinal axis of the housing at a linear edge thereof in the direction of the flow of the fluidic materials flowing through the housing, one end of each said mixing element in the radial direction of the housing being fixedly disposed in the inner wall of the housing, a suitable space being formed between another end of each said mixing element and the adjacent inner wall thereof so that materials trapped by said element are permitted to pass therethrough.
