Publication number: 20100256317Abstract: Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing —Si(OR?)3 (where R? is H, an alkyl group, Na, K, or NH4) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical.Type: ApplicationFiled: June 15, 2010Publication date: October 7, 2010Applicant: CYTEC TECHNOLOGY CORP.Inventors: Donald P.

Patent number: 5733460Abstract: The processing of bauxite in the Bayer Process results in the formation of titanaceous, siliceous, and other scale on equipment and apparatus such that a great deal of time and effort is spent in order to maintain the process at its height efficiency by reducing or eliminating the same. The scale is treated, reduced, altered, etc., according to the present invention by the use of hydroxamated polymers having weight average molecular weights of over about 10,000.Type: GrantFiled: April 29, 1996Date of Patent: March 31, 1998Assignee: Cytec Technology Corp.Inventors: Alan S.

Patent number: 5306166Abstract: A chip storage and insertion guide includes a generally rectangular plastic housing with a top wall, side walls and end walls. The end walls define guide posts for insertion into matching apertures in a printed circuit board. The side walls are configured so that the pins of a new chip are bent inwardly slightly as the chip is gently forced into the rectangular guide until it is flush against the inside of the top wall. A handle portion of a pivoted arm mechanism extends transversely across the top wall at each end of the housing. Pivot arms at each end of the handle extend down the side walls and are attached thereto with pegs pivotally engaged in notches formed in the side walls. When the two arm mechanisms are pivoted outwardly, a shoulder portion of each arm moves upwardly to align a camming surface with the lower edge of the side walls thereby enabling the chip to be inserted in the socket of the printed circuit board.Type: GrantFiled: December 14, 1992Date of Patent: April 26, 1994Assignee: Wyse Technology, Inc.Inventors: Frank Kula, Luis Arreola
