Publication number: 20240084051Abstract: Disclosed are support-activators and catalyst compositions comprising the support-activators for polymerizing olefins in which the support-activator includes clay heteroadduct, prepare from a colloidal phyllosilicate such as a colloidal smectite clay, which is chemically-modified with a heterocoagulation agent. By limiting the amount of heterocoagulation reagent relative to the colloidal smectite clay as described herein, the smectite heteroadduct support-activator is a porous and amorphous solid which can be readily isolated from the resulting slurry by a conventional filtration process, and which can activate metallocenes and related catalysts toward olefin polymerization. Related compositions and processes are disclosed.Type: ApplicationFiled: October 11, 2023Publication date: March 14, 2024Applicant: Formosa Plastics Corporation, U.S.A.Inventors: Michael D.

Patent number: 9283567Abstract: A shredder has a jam proof system with a thickness detector having a contact member which displaces as an article is inserted into the shredder and a resistance generating mechanism which provides a resistance force to the contact member, in response to its displacement. The greater the thickness of the article, the greater the resistance force realized. When a predetermined thickness is reached, there is a significant change in the resistance force. The resistance generating mechanism may include at least two spring mechanisms and provide feedback to the user that the inserted article may be too thick. In addition, the thickness detector may include a thickness sensor. The sensor may communicate with a controller to alert the user, and/or alter the operation of the shredder, in response to the thickness of the inserted article. For example, the controller may visually and/or audibly alert the user, or control shredder motor response.Type: GrantFiled: December 22, 2011Date of Patent: March 15, 2016Assignee: FELLOWES, INC.Inventors: Jin Hu, Qingcheng Cai, Aiyu Huang, Michael D Jensen
