Abstract: A multifunctional organosilicon compound is provided which has the general formula XSi([OSiR2]p-0-SiR2Y)a(R1)3-a— ln the formula, X is selected from H and ethylenically un saturated moieties; each Y independently comprises a functional moiety selected from alkoxysilyl moieties, acryloxy moieties, and epoxide moieties; each R is an independently selected hydrocarbyl group; each R1 is an independently selected hydrocarbyl group; subscript a is 1, 2, or 3; and each subscript b is independently 0, 1, or 2. A method of preparing the multifunctional organosilicon compound is also provided. The method comprises reacting (A) an organosilanol compound and (B) a silane compound having at least two hydrolysable groups. A functionalized siloxane compound prepared from the multifunctional organosilicon compound, a method of preparing the functionalized siloxane compound, and an adhesive comprising the functionalized siloxane compound are also provided.

Abstract: A method can selectively prepare a compound of formula (IV), where each R1 and each R2 are independently selected from an alkyl group, an aryl group, a halogenated alkyl group, or a halogenated aryl group of 6 to 10 carbon atoms each R3 is an alkane-diyl group, and each R4 is hydrogen or an alkyl group. The method involves hydrosilylation of an organohydrogensiloxane oligomer with a carboxylic acid alkenyl ester using an iridium complex catalyst.

Abstract: Pumping and measuring apparatus for fluid metals comprising an electromagnetic pump which operates in two modes; first, an idling mode in which the pump operates at one rate of flow and continually circulates fluid metal out of a reservoir, through an opening in a conduit and back to the reservoir; second, a delivery mode in which the pump operates at a higher rate of flow and circulates fluid as in the idling mode, and further raises the fluid metal to a higher opening in the conduit for delivery therethrough. A timing control for selectively adjusting the durations of each mode as well as the time intervals between modes allows high accuracy of measurements of quantities of fluid metal delivered.
