    Abstract: A fill tube assembly is for a casting mold. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular member has a substantially, uniform cross-section. A clamping assembly is structured to maintain a substantially leakproof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations. A method of use is also disclosed.

  • Patent number: 5954261
    Abstract: A mold for joining conductors such as stranded cable to each other and to other elements such as a ground rod is formed of two or more parts. The mold formed by the parts includes a weld chamber. Exothermic welding material in a crucible above forms molten metal which drops into the weld chamber through a tap hole. The mold includes sleeving passages extending upwardly at an angle from horizontal to exit the mold well above the level of molten metal forming the weld. The sleeving passages extending upwardly at an angle from the weld chamber, or as a V with two symmetrical passages, are preferably larger than normal passages and accordingly will accommodate a wide variety of cable sizes without interference with or abrasion of the sleeving passages. This enables one mold to accommodate more sizes, avoids the use of packing, adapter sleeves or shims, and maintains the weld chamber well vented.

  • Patent number: 4917587
    Abstract: The invention relates to an apparatus for the production of building units from an afterhardening mixture containing cement and/or lime as binding material. The raw mixture is continuously fed and pressed by stamping into a die with CO.sub.2 gas at a pressure higher than atmospheric being passed through the raw mixture in the die space. Through an instantaneous reaction of carbonation, the material is hardened to a formed body. The CO.sub.2 gas is prevented from escaping by a gastight seal in the vicinity of the inlet port of the die. Further towards the outlet port, the pressure of the CO.sub.2 gas is decreased. In the vicinity of the outlet port only as much CO.sub.2 gas is fed as is necessary for the completing of the chemical reaction. Thus, any loss of gas will be minimized. The continuously discharged body is cut to size by using a saw.
