Patent number: 6313193Abstract: An antifouling coating formulation includes a first part making up the matrix of the coating. The first part is a silicone-modified titanium silicate glass. A second part of the formulation serves to prevent barnacles and other organisms from attaching to the coating and includes a combination of liquid polymers, oils, or liquid waxes which are incompatible and will phase separate after the mixing. The materials have a chemically reactive group which serve to graft the materials into the matrix. An optional third part of the formulation includes a compound which prevents or inhibits slime formation.Type: GrantFiled: June 2, 2000Date of Patent: November 6, 2001Assignee: Microphase Coatings Inc.Inventor: William H.

Patent number: 5742223Abstract: An electrical device in which a first resistive element which is composed of a first electrically non-linear composition is in electrical contact, and preferably in physical and electrical contact, with a second resistive element which is composed of a second composition which has a resistivity of less than 100 ohm-cm. The first composition has a resistivity of more than 10.sup.9 ohm-cm and contains a first particulate filler. The second composition contains a second particulate filler which (a) is magnetic and electrically conductive, and (b) is aligned in discrete regions in the second polymeric component. The device also contains first and second electrodes which are positioned so that current can flow between the electrodes through the first and second resistive elements. Devices of the invention have relatively low breakdown voltages and can survive high energy fault conditions.Type: GrantFiled: December 7, 1995Date of Patent: April 21, 1998Assignee: Raychem CorporationInventors: William H. Simendinger, III, Charles A. Boyer, Rudolf R. Bukovnik
