Abstract: Rye grass lines, designated 71548 and 71550 are disclosed. The invention relates to the seeds of inbred rye grass lines 71548 and 71550, to the plants of inbred rye grass lines 71548 and 71550 and to methods for producing a rye grass plant by crossing the inbred lines 71548 or 71550 with itself or another rye. grass line. The invention further relates to hybrid rye grass seeds and plants produced by crossing the inbred lines 71548 or 71550 with another annual wheat or annual rye grass line.

Abstract: A process comprising heating coal in a substantially air-free environment to liberate volatile materials and produce coke, condensing at least some of the volatile materials so liberated to liquefied products and dispersing the coke therein to form a coke slurry, feeding the coke slurry to a slurry pipeline, and pumping the coke slurry through the pipeline to a destination.Apparatus comprising a tube furnace having an external heating means for indirectly heating powdered coal therein in a substantially air-free environment to a temperature adequate to liberate volatile materials and produce coke, means to feed powdered coal to the furnace under pressure and force the volatile materials and coke produced in the furnace through the furnace to a condensing means in which at least some of the volatile materials are condensed with the coke dispersed therein to form a coke slurry, and means to convey the coke slurry from the condensing means to a pipeline for transport to a destination.

Abstract: A system for thermal disposal and port improvement comprising an industrial plant constituting a source of hot cooling water which must be cooled located along a navigable river, lake or ocean, a body of water constituting a port in the vicinity of the industrial plant and in navigable communication with the river, lake or ocean, means for delivering hot cooling water from the industrial plant to the port water to cool the water throughout the year and to prevent it from freezing shut in winter, and means for removing cool cooling water from the port water and delivering it to the industrial plant and/or to a river, lake or ocean.
