Abstract: An externally heated cast iron vessel, intended for containing a reactive molten metal, such as aluminum, is made resistant to attack by the molten metal, thereby increasing its useful service life and minimizing contamination of the melt, by lining the inside of the cast iron shell with a plurality of inert self-supporting, refractory plates, of for example, graphite, in such manner that the plates are free to move along their joints as well as relative to the shell upon thermal expansion, and permitting the molten metal to penetrate behind the lining through the joints and crevices therein opened by thermal expansion, thereby producing a refractory layer, in situ in the space between said lining and the inside surface of said cast iron shell, comprising a solid (FeAl.sub.3) reaction product of iron and said molten metal.

Abstract: In an apparatus for stuffing flowable product into a shirred tubing disposed on a stuffing horn to produce stuffed tubular articles of predesired length on a continuous basis, a sensing member is employed for detecting movement of the trailing end portion of the shirred tubing on the stuffing horn which activates control for interrupting the stuffing operation of the apparatus so as to terminate the flow of product from the stuffing horn before the shirred tubing is completely expended.

Abstract: This invention relates to improving the known process for disposing of refuse while simultaneously producing a useful gaseous product and an inert solid residue in a shaft furnace in which refuse is fed into the top portion of said furnace, an oxygen containing gas is fed into the base, and in which the organic portion of the refuse is pyrolized to char, oils and gas containing a high concentration of CO and H.sub.2, and the inorganic portion of the refuse is fluidized and tapped from the base of the furnace.The improvement in the above-described process comprises removing a portion of the char from the furnace while retaining a sufficient amount of combustible materials in the furnace to satisfy the energy requirements of the process. The improvement permits a reduction in the oxygen requirements of the process and has a beneficial effect on the specific heating value of the fuel gas produced.

Abstract: An improved process for producing pitch which is transformed, in part, to a liquid crystal or so-called "mesophase" state. According to the process, the mesophase content of the pitch is formed while agitating the pitch so as to produce a homogeneous emulsion of the immiscible mesophase and non-mesophase portions of the pitch. Mesophase pitches prepared in this manner have been found to possess a lesser amount of high molecular weight molecules in the mesophase portion of the pitch and a lesser amount of low molecular weight molecules in the non-mesophase portion of the pitch, and thus a smaller differential between the average molecular weights of the mesophase and non-mesophase portions of the pitch, than mesophase pitches having the same mesophase content which have been prepared in the absence of such agitation.
