Abstract: Abstract of the Disclosure Method and apparatus for electrical logging in a mud-filled borehole by sensing redox potential and other formation characteristics. An elongated, tubular probe body contains spaced-apart reference and potential measuring electrodes which extend longitudinally thereof and are adapted to make external contact with the borehole fluid at the stream-lined surface of the probe nose. The reference electrode is a chemical type formed of a metal electrode immersed in an electrolyte-filled compartment separated from the external borehole fluid by a pressure-compensating diaphragm in the probe side wall. A fluid bridge is established between the lower end of the reference electrode and the mud of the bore-hole through the insertion of a permeable ceramic wick. The diaphragm substantially equalizes pressure between the bore-hole fluid and the electrolyte so as to prevent either loss or contamination of the electrolyte, a feature not found in prior art devices. An optional heavy electrolyte compartment within the probe body may be interposed between the sidewall diaphragm and the reference electrode, thus maintaining a positive leak pressure into the mud even under high pressure borehole conditions.

Title: Process for recovery of high-grade lecithin and solvents from ternary solvent system containing crude vegetable oil
Inventor: SHORT ROBERT G
IPC: A23J7/00
Filed: 1978-07-06
Granted: 1981-12-08
Abstract: ABSTRACT        A method of recovering a high-grade lecithin and solvents from an oil-bearing full miscella which also contains lecithin and which results from an oilseed ternary solvent extraction process. The method may include a first step of phase separation of the oil-bearing miscella containing lecithin and the ternary solvents into a polar and a non-polar phase, and a second step of azeotropic distillation of the non-polar phase to recover a portion of the solvents, and to remove substantially all the water from the residual crude oil, thereby keeping the lecithin in solution. A commer-cial grade lecithin having good water dispersibility is subsequently recovered from the residual crude oil, and a small amount of highly water dispersible lecithin may be recovered from the polar phase by atmospheric distillation.      In another embodiment, when the full miscella containing crude oil ternary solvent and lecithin resulting from the above ternary solvent extraction is initially subjected to azeotropic distillation to recover solvent therefrom and remove substantially all the water, a highly water dispersible lecithin having a high choline chloride content is obtained. Premature degumming of this highly water dispersible lecithin is avoided by maintaining the solvent rations above certain minimums.    The ternary solvents for the oilseed extraction include a lipo-philic hydrocarbon, such as hexane; a water miscible lower alcohol, such as ethanol; and a minor amount of water. The recovery method is energy efficient, because the boiling temperature of the ternary azeotrope is lower than any other combination of the three solvents.

Abstract: Abstract of the Disclosure This invention relates to a method of producing patterns upon a substrate using resist-like ink patterns by applying on the surface of the substrate a pattern of an ink selected from oil modified alkyd resin and drying oil vehicle inks, drying the ink pattern and after suitable treatment of the unprotected portions. e.g.. by etching, removing the ink pattern from the substrate; the improvement resides in rendering the ink pattern relatively easily strippable by a modifying powder comprising a petroleum resin, heating the powdered pattern to fuse the powder into a coating for the ink pattern and removing, after said suitable treatment the coated ink pattern with a suitable solvent which will dissolve or strip the coated ink pattern without adversely reacting with the substrate.  The process is especially useful in the manufacture of printed circuit boards.
