Patent number: 6168090Abstract: A flame spray system employs splatter blocking and automated rod delivery apparatuses. The splatter blocking apparatus includes a barrier member and an actuation mechanism. The barrier member is adapted to be moved between a blocking position in which the barrier member is extended across a spray path from a flame spray gun of a flame spray system preventing travel of particles of fusible material from the flame spray gun to a product being coated and an unblocking position in which the barrier member is displaced from the spray path of the flame spray gun permitting travel of particles fusible material from the flame spray gun to the product being coated. The actuation mechanism is connected to the barrier member and adapted to be selectively actuated to move the barrier member between the blocking and unblocking positions.Type: GrantFiled: December 31, 1998Date of Patent: January 2, 2001Inventor: Edgar C. Baker

Patent number: 5510433Abstract: A process for the production of EPM or EPDM comprising contacting ethylene, propylene, and, optionally, one or more dienes, in a fluidized bed, at a temperature at or above the sticking temperature of the product resin, under polymerization conditions, with(i) a prepolymer containing a transition metal catalyst precursor with the proviso that the prepolymer is not sticky at the process temperature;(ii) a hydrocarbyl aluminum and/or a hydrocarbyl aluminum halide cocatalyst,; and, optionally,(iii) a halocarbon promoter; and, optionally,(iv) an inert particulate material having a mean particle size in the range of about 0.01 to about 150 microns wherein the particulate material is either contained in the prepolymer or is independent of the prepolymer,wherein the amount of prepolymer or the combined amount of prepolymer and inert particulate material is sufficient to essentially prevent agglomeration of the fluidized bed and the product resin.Type: GrantFiled: September 23, 1994Date of Patent: April 23, 1996Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Edgar C. Baker, Jose F. Cevallos-Candau, Fathi D. Hussein, Kiu H. Lee, Allen Noshay

Patent number: 5449118Abstract: A control apparatus is coupled to a flame spray gun for controlling the rate of feeding of a rod of heat fusible material through the gun. The control apparatus includes an electric motor adapted to be drivingly coupled to a flame spray gun and being operable in response to application of a D.C. voltage thereto to generate rotary motion to produce and control feeding of a rod of heat fusible material through the flame spray gun, an A.C. to D.C. converter and regulator device for generating and applying the D.C. voltage to the electric motor, a manually adjustable potentiometer connected to the converter and regulator to vary the quantity of D.C.Type: GrantFiled: June 14, 1994Date of Patent: September 12, 1995Inventor: Edgar C. Baker

Patent number: 5324798Abstract: A finishing process for a polymer containing an active catalyst residue. Starting polymer has a crystallinity of less than 10 percent by weight and is maintained in an essentially oxygen free reaction zone at a temperature less than polymer sticking temperature. The polymer is stabilized and acids neutralized by adding 2, 6-di-tert-butyl-4-alkyl phenol and/or alkyl -3-(3-5 -di-tert-butyl-4-hydroxy phenyl)- propionate and zinc oxide, hydrotalcite, or a zeolite. Resulting polymer is then treated with catalyst deactivators including water, and then mixed with photo-oxidative stabilizers.Type: GrantFiled: December 28, 1992Date of Patent: June 28, 1994Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Janice E. Sanders, George N. Foster, Edgar C. Baker, Robert J. N. Bernier
