Abstract: Amino-functionalized cyclic oligosiloxanes, which have at least three silicon and three oxygen atoms as well as at least one organoamino group and methods for making the oligosiloxanes are disclosed. Methods for depositing silicon and oxygen containing films using the organoamino-functionalized cyclic oligosiloxanes are also disclosed.

Abstract: An apparatus for the therapeutic exercise and rehabilitation of injured fingers is comprised of a backboard upon which the dorsal side of the patient's hand is rested, a strap to secure the hand to the baseboard and provide necessary leverage for exercises and an immobilization bar which is used to anchor the proximal or middle phalanges to the backboard thereby isolating the proximal and distal interphalangeal joints, respectively, and their corresponding muscles for therapeutic exercise. The subject invention is designed for rehabilitation of both the left and right hand and includes means for adaptation to hands of various shape and size.

Abstract: A method and apparatus for monitoring the operation of a froth flotation process comprises sensing variations in solids content of the input stream to the process, varying the dosage of flotation reagent employed in accordance with the input variations, sensing variations in solids content of at least one of the output streams after a predetermined time lapse, comparing the input and output readings with control data relating input and output solids content, and re-adjusting the dosage of flotation reagent dependent on the difference between the actual readings and the control data.
