Abstract: A defined peak region residing between about 3.2 and 3.4 ppm of a proton NMR spectrum of an in vitro biosample is electronically evaluated to determine a level of trimethylamine-N-oxide (“TMAO”). The biosample may be any suitable biosamples including human serum with a normal biologic range of between about 1-50 ?M or urine with a normal biologic range of between about 0-1000 ?M.

Abstract: This invention relates to novel salt compositions and to explosive compositions comprising said salt compositions. The salt compositions are useful as emulsifiers in the explosive compositions. The explosive compositions are water-in-oil emulsion explosives.

Abstract: A combustion modifier for an aqueous hydrocarbon fuel emulsion that reduces nitrogen oxides (NOx), hydrocarbons, carbon monoxide (CO) and particulate matter from the emissions of internal combustion engines. A class of combustion modifiers used in this invention contain nitrogen. The nitrogen-containing combustion modifiers are nitro compounds, hydroxylamines or salts thereof, nitrogen compounds having at least one strained ring group containing from 3 to 5 ring atoms, nitrites, nitramines and mixtures thereof. The non nitrogen-containing combustion modifier comprises compounds containing at least one strained ring compound.

Abstract: A composition of an antioxidant of the formula where R3 is an alkyl group of 2 to 6 carbon atoms, and a dispersant or a detergent, is a useful additive package for lubricant compositions.

Abstract: A saligenin derivative such as the magnesium salt represented by the formula is useful as an additive for a lubricating composition. Preferably X is —CHO or —CH2OH, and Y is —CH2— or —CH2OCH2—. R1 is a hydrocarbyl group containing 1 to 60 carbon atoms and m is 0 to 10. At least one aromatic ring should contain an R1 substituent and the total number of carbon atoms in all R1 groups should be at least 7.

Abstract: The present invention is directed to a composition containing the reaction product of:(A) a cyclic compound containing a 5, 6, or 7-member ring, the ring containing at least one nitrogen and at least one carbonyl group, at least one carbonyl group being adjacent to at least one said nitrogen;(B) an aldehyde or ketone of 1 to about 15 carbon atoms, or a reactive equivalent thereof; and(C) an etheramine represented by the formulaR.sup.4 (O(CH.sub.2 CH(R)O).sub.n --R.sup.3 --NH.sub.2).sub.y(C-I)wherein in formula (C-I), each n independently is a number from 0 to about 50; each R independently is selected from the group consisting of hydrogen, hydrocarbyl groups of 1 to about 16 carbon atoms, and mixtures thereof; R.sup.3 is selected from the group consisting of hydrocarbylene groups of about 2 to about 18 carbon atoms and groups represented by the formula ##STR1## wherein R.sup.5 and each R.sup.

Abstract: The present invention is directed to a composition made by reacting A) an aldehyde of 1 to 12 carbon atoms or a reactive equivalent thereof; and B) at least one etheramine represented by the formulaR.sup.2 ?O(CH.sub.2 CH(R)O).sub.n --R.sup.1 --NH.sub.2 !.sub.y(I)wherein each n is a number from 0 to about 50; each R is selected from the group consisting of hydrogen, hydrocarbyl groups of 1 to about 16 carbon atoms, and mixtures thereof; each R.sup.1 is selected from the group consisting of a hydrocarbylene group containing 2 to about 18 carbon atoms and a group represented by the formula ##STR1## wherein both R.sup.6 and R.sup.7 are hydrocarbylene groups of about 3 to about 10 carbon atoms and p is a number from 1 to 4; y is 1, 2, or 3; and each R.sup.2 is a hydrocarbyl group having a valence of y and containing 1 to about 50 carbon atoms when y is 1 and 1 to about 18 carbon atoms when y is 2 or 3; y is 1, 2, or 3; provided that when n is zero, y is 1.

Abstract: A railway house car side has an elongated opening closed by four doors disposed in end-to-end relation lengthwise of the car with respect to each other, two of the doors, which may be designated end doors, being movable solely lengthwise of the car to uncover the end portions of the opening, the other two doors, which may be designated center doors, being movable transversely, to disalign them transversely of the car side from the end doors and lengthwise of the side alongside of the end doors to uncover the center portion of the opening. The edges of the end doors nearest the respective ends of the car side have beveled flanges engageable with outwardly diverging door stops on the car side to wedge the end doors against the car side when closed and the opposite edges of the end doors have flanges overlaid by the adjacent center door edges to hold the end doors against the car side, and the edge of one center door overlies that of the other to afford a seal between them.

Abstract: The invention provides a locking device for railway freight car doors including a wedge-shaped locking pin engageable with the hasp for maintaining the door tightly closed, the wedge being so mounted that it need not be withdrawn from locking position to permit release of the lock.
