Patent number: 11737176Abstract: A novel low profile heater apparatus and method of manufacture is disclosed, which provides a lower assembly including a first sheet, a heating sheet including at least one heating element, a dielectric sheet, an intermediate sheet and one or more electrical leads configured to supply electrical power to the heating element, the electrical leads extending through a lead sleeve of an upper assembly. The upper assembly includes a top sheet with one or more split sleeves securely attached thereto, thereby forming one or more strain relief assemblies configured to prevent damage to the electrical leads. One or more stitches or coupling features securely attach the upper assembly to the lower assembly. One or more retention device are be used to securely retain the low profile heater apparatus to one or more pipes, tubes or conduits of a plumbing apparatus.Type: GrantFiled: March 19, 2020Date of Patent: August 22, 2023Inventor: Jeffrey D. Kiernan

Patent number: 10021739Abstract: A trimmable heater mat has a plurality of heater mat segments that together comprise a length of the heater mat. Each of the heater mat segments has a segment heater element connected to a power bus for generating heat. One or more of the heater mat segments can be severed from the others and removed from the heater mat to trim the length of the heater mat to a desired length. Heater mat segment boundary indicia on the heater mat indicate locations where one of the heater mat segments can be severed from the other remaining heater mat segments of the heater mat without interfering with the segment heater elements of the remaining heater mat segments or with the connections of the remaining segment heater elements to the power bus.Type: GrantFiled: July 8, 2015Date of Patent: July 10, 2018Assignee: MKS Instruments, Inc.Inventors: Jeffrey D. Kiernan, Karl Hausmann, Paul Dozoretz

Patent number: 8541716Abstract: A multiple heater control system includes cables, connectors, and junction boxes for user-friendly daisy chain connections of heater controllers and heaters in various configurations or combinations of individually controlled heater series and/or master and slave heater series. The heater controllers include process control of AC power to the heaters and upper-limit safety shutoff that is substantially independent from the process control. The heater controllers also have variable levels of control, adjustment, display, and communications functionality in a base module that is expandable to various levels with expansion modules that are attachable to and detachable from the base module. Connector, cable, and junction configurations, adapters, and latch features enhance user friendliness.Type: GrantFiled: March 15, 2011Date of Patent: September 24, 2013Assignees: MKS Instruments, Inc, Watlow Electronic Manufacturing CompanyInventors: Youfan Gu, Jeffrey D.
