Patent YU-80800-A (YU)
Title: Removal of oxygen from metal oxides and solid solutions by electrolysis in a fused salt
Inventor: FRAY DEREK JOHN
IPC: C22B21/00
Filed: 1999-06-07
Abstract: A method for removing a substance (X) from a solid metal or semi-metal compound (M1X) by electrolysis in a melt of M2Y, comprises conducting the electrolysis under conditions such that reaction of X rather than M2 deposition occurs at an electrode surface, and that X dissolves in the electrolyte M2Y. The substance X is either removed from the surface (i.c. M1X) or by means of diffusion extracted from the care material. The temperature of the fused salt is chosen below the melting temperature of the metal M1. The potential is chosen below the decomposition potential of the electrolyte.

The aliphatic dicarboxylic acid is esterified by heating with the glycol in a molar ratio of from 1:1.2 to 1:1.8 at a temperature of from about 5 to 20°C below the boiling point of the glycol until the degree of esterification is from 90 to 95 mole % based on the aliphatic dicarboxylic acid;  a dialkyl terephthalate is transesterified with the glycol in a molar ratio of from 1:1.2 to 1:2 in the presence of a catalyst in an amount of from 0.01 to 0.2% by weight base on dialkyl-terephthalate by heating to a temperature of from 130° to 240°C at atmospheric pressure until at least 95% of the alkoxy groups present have been eliminated.   The esterification product is mixed with the transesterification product and polycondensation is carried out at a temperature of from 240° to 290°C and a pressure of from 0.1 to 760 mm, in the presence of a catalyst in an amount of from 0.01 to 0.2% by weight based on the polyester.  The polyester obtained is suitable for example for mouldings or as an adhesive.

Title: Method of transporting crude oil at low  temperatures by dispersion in methanol
Inventor: MARSDEN SULLIVAN S JR
IPC: F17D1/16
Filed: 1975-06-04
Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE         Crude oils or tars such as those obtained in arctic areas can be efficiently transported through pipelines at subzero or higher temperatures in the form of a dispersion of the oil in a methanol or a methanol-water dispersing medium.  Thus, oil-methanol or oil-methanol-water dispersions, preferably those containing about 50 to 80 volume percent of the oil which are stabilized by the dispersant, can readily be pumped through buried pipelines at temperatures below 0°C without causing thawing of the permafrost or the frozen body lying adjacent the pipeline.  The necessary methanol can be pre-pared from natural gas produced along with the crude oil or from the gas cap of the same or another oil or gas field, thereby obviating the use of a separate pipeline to transport the natural gases.  The methanol can readily be recovered from the dispersion, for use as a fuel or a chemical raw material, once the dispersion reaches a suitable destination.

Abstract: ABSTRACT OF THE DISCLOSURE          A roller hearth furnace having a plurality of horizon-tally elongated furnace modules aligned with each other in an end-to-end relationship so a roller conveyor may carry glass sheets horizontally through the furnace and thereby heat the glass prior to tempering.  Each furnace module has a hollow con-struction with a circular cross-section defined by a semicircular lower housing portion and a semicircular upper housing portion.          A separate counterbalance mechanism associated with each upper housing portion supports it independently of the others for movement between a lower closed position immediately over its associated lower housing portion and an upper open position where the interior of its associated lower housing portion is acces-sible.  The counterbalance mechanisms each include four chains attached to counterweights in a manner that permits counter-balancing of the associated upper housing portion even if one chain should break.  One chain of each counterbalance mechanism is driven by an associated reversible electric motor to raise and lower its upper housing portion, and a separate elongated operator handle extending along the length of each upper housing portion is coupled to the motor thereof so an operator can con-trol the motor operation from any position along the length of the particular furnace module.  Each upper housing portion includes end walls that mitigate heat loss when one of them is open while adjacent ones are closed.  Upper and lower end walls at each end of the furnace are reinforced to maintain horizontal openings of uniform size where glass enters and leaves the furnace.
