Abstract: An aqueous emulsion which crosslinks by a Michael addition reaction, yielding a crosslinked silicon modified organic composition upon removal of water has been prepared. The aqueous emulsion comprises the product formed by mixing a polymer containing at least two Michael acceptor groups per polymer molecule, water, a surfactant and an effective amount of a crosslinker containing sufficient reactive hydrogens of a Michael donor per crosslinker molecule or a precursor thereto. In order to obtain a crosslinked silicon modified organic composition upon the removal of water, the polymer or the crosslinker must contain at least one silicon atom. The invention also describes a method for making these emulsions.

Abstract: Emulsion copolymerizing a particular crosslinker, i.e., either a siloxane or silazane, with an organic monomer, results in new and novel emulsions. An emulsion can be formed having particles consisting of polymer chains formed from organic monomer. Depending on the crosslinker and reaction conditions, these emulsion polymer chains can be either crosslinked or uncrosslinked. The uncrosslinked polymer chains can be crosslinked at a later point by the addition of a suitable catalyst.

Abstract: The present invention provides waterborne crosslinkable polymer compositions encompassing (A) functional latex polymers containing at least one pendant ethylenically unsaturated functional group, (B) a silicon hydride compound containing at least two reactive hydrogen atoms, and (C) a catalyst suitable to attain a crosslinked film.

Abstract: This invention is directed to a catalyst system for treating internal combustion engine exhaust gases, the system having enhanced hydrocarbon trapping efficiency which is particularly advantageous during cold start. The system comprises a hydrocarbon polymerization catalyst, a hydrocarbon trap located downstream of the hydrocarbon (HC) polymerization catalyst, advanced exhaust treatment catalyst. The hydrocarbon polymerization catalyst is capable of forming larger (HC) molecules from smaller HC molecules.

Abstract: An aqueous silicone emulsion which crosslinks by a Michael addition reaction, yielding a cured composition upon removal of the water has been prepared. The aqueous silicone emulsion comprises the product formed by mixing an organosiloxane polymer containing at least two Michael acceptor groups per organosiloxane molecule, water, a surfactant and an effective amount of a crosslinker having sufficient reactive hydrogens of a Michael donor per crosslinker molecule. The invention also describes a method for making these silicone emulsions.

Abstract: A semi-truck trailer gooseneck assembly comprises a single curved plate extending transversely between and beyond the twin parallel longitudinal girders to form a single lower flange. The curved plate extends from the assembly supporting the floor over the fifth wheel and connecting the king pin to the trailer. The rear portion of the curved plate extends to the horizontal flat lower flanges of the twin girders extending substantially the length of the trailer. The result is a structure of increased strength and moment of inertia permitting the web depth of the gooseneck to be substantially decreased.The rear corner post comprises a two piece welded assembly wherein the major section is substantially an elongated "S" and the minor section "L" shaped. The shapes are welded together to form a hollow center portion and a pocket portion. The "L" section forms a contact for the rear door and the pocket engages the curtain to enable the curtain to be fully tightened when closed.

Abstract: Loops are created at the ends of a woven papermaking machine forming fabric by a method which comprises removing weft yarns from the end of the fabric to give a weft-free zone, shortening selected ones of the warp yarns in the region of the weft-free zone, folding back the uncut warp yarns into register with respective ones of the shortened warp ends to form loops spaced transversely of the fabric, and introducing weft yarns into the resultant weftless end of the forming fabric, the crimp pattern of the individual uncut warp ends being such that when the ends are folded back the overall crimp pattern of the warp yarns in the weftless end of the forming fabric is compatible with that of the body of the forming fabric.

Abstract: The instant invention describes an improvement in a starter-generator arrangement in which a dynamoelectric machine is driven as a brushless DC motor to start a dynamic load such as a jet engine and as a cynchronous constant frequency generator after the jet engine is ignited and brought up to speed. A plurality of cycloconverters utilizing phase controlled rectifier banks are operated from a constant frequency supply source to supply current to the armature windings of the machine in the starting mode. Position sensing elements such as Hall generators sense the rotor position relative to the machine windings and generate enabling signals to control conduction of the phase controlled rectifiers to supply current to the proper armature windings so that the machine functions essentially as a DC brushless motor to drive a dynamic load such as a jet engine.
