Patent number: 4362868Abstract: Plasticized cellulose polymers comprise a base polymer having a chain of .beta.-anhydroglucose units joined by ether linkages and having ether substituents, with at least one of the units being additionally substituted, by esterification of at least one hydroxyl group, by at least one ester group, which contains at least two carbon atoms and is chemically unreactive.Preferably the ester group contains four or more, most preferably five, carbon atoms. The carbon chains of the ester groups may be straight or branched.These internally plasticized celluloses may be prepared by, for example, reacting the base polymer with a carboxylic acid in xylene or with an acid chloride or anhydride in pyridine. They are useful in particular as inhibitor coatings for rocket motor propellants and in general wherever cellulose polymers are employed.Type: GrantFiled: September 19, 1980Date of Patent: December 7, 1982Assignee: The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britian and Northern IrelandInventors: Michael Burnup, Gerard F.

Patent number: 4334883Abstract: A process for separating isotopes by selective excitation of isotopic species of a volatile compound by tuned laser light. A highly cooled gas of the volatile compound is produced in which the isotopic shift is sharpened and defined. Before substantial condensation occurs, the cooled gas is irradiated with laser light precisely tuned to a desired wavelength to selectively excite a particular isotopic species in the cooled gas. The laser light may impart sufficient energy to the excited species to cause it to undergo photochemical reaction or even to photoionize. Alternatively, a two-photon irradiation may be applied to the cooled gas to induce photochemical reaction or photoionization. The process is particularly applicable to the separation of isotopes of uranium and plutonium.Type: GrantFiled: August 14, 1973Date of Patent: June 15, 1982Assignee: The United States of America as represented by the United States Department of EnergyInventors: C. Paul Robinson, Reed J. Jensen, Theodore P. Cotter, Norman R. Greiner, Keith Boyer

Patent number: 4253161Abstract: Disclosed is a cross-tie wall memory system for the generating, propagating and detecting of binary data represented by the presence or absence of cross-tie, Bloch-line pairs along a cross-tie wall in a thin magnetic data track. The system includes a three-level shift register structure comprised of the following layers: first and second substantially similar, serrated-edged current conductive striplines and a serrated-edged thin magnetic layer data track. The shift register is terminated on one end by a cross-tie, Bloch-line pair generator and on the other end by a cross-tie detector. A data word is stored in the data track between the generator and the detector and is shifted through the detector for readout of the stored data word. The first and second serrated-edged striplines are formed of alternate wide-narrow portions with the wide portion of one stripline oriented above/below the narrow portion of the other stripline.Type: GrantFiled: October 15, 1979Date of Patent: February 24, 1981Assignee: Sperry CorporationInventors: Maynard C.

Patent number: 4253160Abstract: Disclosed is a cross-tie wall memory system for the generating, propagating and detecting of binary data represented by the presence or absence of cross-tie, Bloch-line pairs along a cross-tie wall in a thin magnetic layer. The system includes a three-level structure comprised of the following superposed layers: a straight-edged current conductive stripline; a serrated-edged thin magnetic layer data track, and a wide-narrow-edged current conductive stripline terminated on one end by a cross-tie, Bloch-line pair generator. A cross-tie detector is positioned intermediate the ends of the data track and is sandwiched between the data track and the wide-narrow-edged current conductive stripline. An N-bit data word is stored in the data track between the generator and the detector, is shifted through the detector for readout of the stored data word and is then restored into its original stored position by being shifted in a reverse manner along the data track and back through the detector.Type: GrantFiled: September 6, 1979Date of Patent: February 24, 1981Assignee: Sperry CorporationInventors: Maynard C.

Patent number: 4231335Abstract: In a system including a carburetor for regulating the air/fuel ratio fed to an internal combustion engine, a sensor is positioned in the exhaust pipe to provide a control signal indicating the amount of some exhaust gas constituent, such as oxygen. A control circuit is provided to regulate the position of a carburetor component, to change the air/fuel ratio as a function of the control signal derived from the exhaust gas sensor. This carburetor component is continually displaced, either toward a richer or leaner mixture condition, thus in effect integrating the signal from the exhaust gas sensor which ultimately regulates the air/fuel ratio. Operation of the control circuit is modified as a function of the engine speed and the engine temperature.Type: GrantFiled: April 6, 1979Date of Patent: November 4, 1980Assignee: Borg-Warner CorporationInventors: Irving H. Hallberg, Howard C. Paul, Ronald R. Ralston, Roy E. Hunninghaus

Patent number: 4208725Abstract: A method of and a detector for magneto-resistively reading out the information that is stored in a cross-tie wall memory system. The detector includes two current conductive elements that are positioned along and across the cross-tie wall in a magnetic film that is configured into a data track for sandwiching a plurality of memory cells therebetween. A separate current conductive element is centered over each of the sandwiched memory cells for conducting the read current drive signal out of the data track in the area of the Bloch-line, but forcing the read current drive signal through the data track in the area of the cross-tie. A stored binary 1, represented by a cross-tie, Bloch-line pair, is propagated into one end of the detector and is replicated in all of the sandwiched memory cells; conversely, a stored binary O, represented by the absence of a cross-tie, Bloch-line pair, would be replicated in all of the sandwiched memory cells.Type: GrantFiled: February 23, 1979Date of Patent: June 17, 1980Assignee: Sperry CorporationInventors: Maynard C. Paul, David S. Lo

Patent number: 4198686Abstract: A method of and an apparatus for counting is disclosed. The counter includes a generator of cross-tie, Bloch-line pairs and a shift register of N stages or memory cells along which the cross-tie, Bloch-line pairs are propagated or replicated into a detector. The method includes coupling a series of bipolar push-nucleate replicate signals, each one of which produces a cross-tie, Bloch-line pair in the adjacent downstream memory cell along the shift register. When the shift register is filled, a cross-tie will appear in the detector. This provides an output signal indicating that the N memory cells have been filled by the N replicate signals.Type: GrantFiled: February 23, 1979Date of Patent: April 15, 1980Assignee: Sperry CorporationInventors: George F. Nelson, Gregory J. Cosimini, Leslie H. Johnson, David S. Lo, Maynard C. Paul, Ernest J. Torok

Patent number: 4161789Abstract: A method of and an apparatus for reading out the information that is stored in a magnetizable layer that is formed of a thin film in which data are stored as inverted Neel wall sections about associated Bloch-lines along a cross-tie wall. The apparatus utilizes a magnetizable layer which is configured into a strip whose two opposing edges are, along its longitudinal axis, formed into mirror-imaged, spaced-apart, repetitive, asymmetrically-shaped patterns which repetitive patterns are formed of successive narrow portions that form wide portions therebetween. The repetitive patterns, when suitable magnetic fields are coupled thereto, form a cross-tie wall along the longitudinal axis of the strip while structuring the cross-ties along the cross-tie wall at the narrow portions and the Bloch-lines along the cross-tie walls and between the adjacent narrow portions.Type: GrantFiled: July 3, 1978Date of Patent: July 17, 1979Assignee: Sperry Rand CorporationInventors: Ernest J.
