  • Patent number: 4289475
    Abstract: For use as a replacement for existing gas to burners, oil having an API gravity of about 10-80 is preheated and mixed with about 0.1 to 1 pound of steam per pound of oil, at a pressure of about 30-150 pounds per square inch gauge. The resulting mixture is heated to a temperature above the condensation temperature of the mixture, the temperature being approximately in the range of 450.degree.-800.degree. F. The mixture has flow properties which are essentially equivalent to those of gas under the same conditions of temperature and pressure. The mixture is delivered to the nozzle of the gas burner and is burned therein.An apparatus is provided for burning either oil or gas, and includes a gas burner having nozzle means for mixing air and gas, a gas conduit connected thereto, and an oil supply also connected to the burner, the oil supply being fed from an oil vaporizing apparatus as just described above.

  • Patent number: 4289875
    Abstract: A process for the continuous filtration and aging of a viscose solution comprising xanthated alkali cellulose (XAC) is described wherein the XAC is continuously passed in a downstream direction through a series of aging tanks and a series of filter means. The aging tanks are so designed and arranged that the viscose solution is never partitioned into batches, as necessitated by common manufacturing systems, but constitutes a continuous, uninterrupted stream throughout aging filtration, deaeration and spinning. The filter means, standard plate and frame filters, are designed and installed in such a manner that the number of filter changes, or redressings, are substantially reduced in the aggregate, without increasing the number of filters now used in a standard plant, or sacrificing viscose quality. This results in less process interruption, loss of product, and less potential environmental pollution.

  • Patent number: 4283823
    Abstract: A thermostatically controlled valve, of the type used in a cooling system of an internal combustion engine, has a temperature-responsive actuating member, for opening and closing the valve, in the form of a metal coil having shape memory effect such that its modulus of elasticity increases rapidly at a critical temperature. The actuating member is calibrated prior to assembly in the valve by heating the member to the critical temperature and reducing its length to that at which the valve will begin to open by cutting the member while preventing overheating.
