Patent number: 7491791Abstract: A method for treating polytetrafluoroethylene (PTFE) in its reactor latex form to produce a dry submicron PTFE powder that remains stable without rheology modifiers, surfactants, wetting agents, pH adjusters or other stabilizing additives. Reactor latex PTFE formed during an emulsion polymerization process can be irradiated, with an electron beam or gamma rays, during or after the polymerization to form a product where the dry submicron PTFE powder is free-flowing, tends not to self-agglomerate and tends not to dust into the air upon handling so that the PTFE is readily dispersible when placed in a desired application system or medium.Type: GrantFiled: January 26, 2004Date of Patent: February 17, 2009Assignee: Shamrock Technologies Inc.Inventors: Charles A. Cody, William Neuberg, Manshi Sui, Youssef Awad, Paul Carey

Patent number: 7482393Abstract: A method for producing submicron polytetrafluoroethylene (“PTFE”) powder in a free-flowing, readily dispersible form. The irradiated PTFE starting material is placed in a desired solvent and undergoes grinding until the PTFE particles reach submicron size. The submicron particles are subsequently recovered from the solvent and dried to form a powder that may have particles less than 1.00 ?m in size. The dry PTFE powder may then be readily dispersed to submicron size into a desired application system. The submicron PTFE powder of this method is free-flowing, readily dispersible in various application systems, tends not to “dust” or self-agglomerate. Improved aqueous and organic dispersions of submicron PTFE particles may also be formed that display increased stability and require much less agitation than other processes of forming such dispersions. Such improved PTFE dispersions may be formed with or without the addition of surfactants, wetting agents, rheology modifiers, pH-adjusting agents, and the like.Type: GrantFiled: December 29, 2004Date of Patent: January 27, 2009Assignee: Shamrock Technologies Inc.Inventors: Charles A.

Patent number: 6176987Abstract: A robotic arm assembly in a transport module is expansible to have an effector at its end receive a substrate in a cassette module and is then contracted and rotated with the effector to have the effector face a process module. Planets on a turntable in the process module are rotatable on first parallel axes. The turntable is rotatable on a second axis parallel to the first axes to move successive planets to a position facing the effector. At this position, an alignment assembly is aligned with, but axially displaced from, one of the planets. This assembly is moved axially into coupled relationship with such planet and then rotated to a position aligning the substrate on the effector axially with such planet when the arm assembly is expanded. A lifter assembly aligned with, and initially displaced from, such planet is moved axially to lift the substrate from the effector. The arm assembly is then contracted, rotated with the effector and expanded to receive the next cassette module substrate.Type: GrantFiled: January 27, 1997Date of Patent: January 23, 2001Assignee: Shamrock Technology Corp.Inventors: Robert George Begin, Peter J.

Patent number: 6159290Abstract: An end effector in a robotic arm assembly receives a substrate in a cassette module and moves the substrate into a process module. A turntable rotatable on a fixed axis rotates a stator and a planet in the process chamber to a position of the planet in axial alignment with the end effector in the process chamber. A lifter assembly axially aligned with, and initially axially displaced from, the axially aligned planet is moved axially to lift the substrate from the end effector. The end effector is then withdrawn by the robotic arm assembly from the process chamber and the substrate is deposited by the lifter assembly on the axially aligned planet. When successive substrates have been sequentially deposited on a plurality of planets in the process chamber in the manner described above, the planets are individually rotated by the turntable relative to the stator on a second axis displaced from the first axis. The stator has peripheral teeth which mesh with teeth on the planets, the teeth being constructed (e.g.Type: GrantFiled: October 2, 1998Date of Patent: December 12, 2000Assignee: Shamrock Technology Corp.Inventors: Peter J.

Patent number: 6135051Abstract: An end effector in a transport module includes a body and a web defined by a panel and first and second flanges at opposite panel ends. The first flange is attached to the body. The second flange is displaced from, and transverse to, the panel. Rods extending through the flanges into the body rigidify the web. Springs disposed in holes in the body and extending between the first flange and the body balance the web relative to the body. The second flange and a ledge on the body adjacent the first flange support the substrate opposite ends with the central portion of the substrate displaced from the body and the web. A robotic assembly formed from a plurality of arms is coupled to the body. The arms are pivotable relative to one another and to the body between contracted and expanded relationships. With the arms contracted, the body and the web are rotatable in the transport module between positions facing the cassette module or the process module.Type: GrantFiled: April 15, 1998Date of Patent: October 24, 2000Assignee: Shamrock Technology Corp.Inventor: Robert George Begin
