Patent number: 6507267Abstract: A spring clip is attached to a thermostat bottom wall for attaching the thermostat to tubing in heat exchange relationship. The spring clip has an opening that faces transversely of the thermostat longitudinal axis so that installation forces act in a direction that is more parallel to the bottom wall to avoid denting of the bottom wall. The spring clip has a flat mounting base attached to the thermostat bottom wall to spread forces over a large area of the bottom wall and to reinforce the bottom wall against deformation.Type: GrantFiled: March 22, 2002Date of Patent: January 14, 2003Assignee: Therm-O-Disc, IncorporatedInventors: Larry Russell, Tung-Sheng Yang, Frank Winter, Mark Rader

Patent number: 5877671Abstract: A temperature controller comprises a bimetallic switching mechanism that switches in response to a predetermined temperature, a lower housing part receiving the switching mechanism, a cover part closing off the lower housing part, and a substantially inert film that is arranged between the lower housing part and the cover part. The substantially inert film comprises a polyimide. The film comprises a mechanical seal between the lower housing part and the cover part.Type: GrantFiled: June 13, 1997Date of Patent: March 2, 1999Inventor: Marcel Hofsass

Patent number: 5859579Abstract: Such switches have current connections for contacts. One contact may be a fixed contact and the other contact may be a mobile contact. A drive opens the mobile contact when a predetermined electric current intensity is exceeded. The electric drive is a thermoelectric drive. For that purpose, the contacts (2,3) are arranged in a closed housing (1) made of an insulating material and a disk-shaped resistive member (4) is arranged between the contacts (2,3). A switch of this type may also be advantageously designed as a bistable limiter.Type: GrantFiled: January 26, 1996Date of Patent: January 12, 1999Assignee: Siemens AktiengesellschaftInventors: David Walter Branston, Jorg Kieser, Werner Hartmann, Reinhard Maier

Patent number: 5367281Abstract: A striker pin device for providing a visual indication of an operated condition of an associated fuse, comprising a tubular housing coaxially arranged within the fuse with an end of the housing in contact with an end of the fuse. The tubular housing has a closure structure comprised of a one-piece integrally formed closure member having a projection protruding out of the housing and an opened end with a cavity. A piston with a central projection received in the opened end of the closure member forms a gas tight enclosure containing pyrotechnic material. An ignition element is attached to a brass pin which extends through the projection of the closure member and is connected to a tubular terminal or electrical conductor member which is attached to a high resistance pilot wire, which is stretched through the fuse.Type: GrantFiled: December 30, 1993Date of Patent: November 22, 1994Assignee: Eaton CorporationInventor: William R. Crooks

Patent number: 4303827Abstract: An electric heating appliance such as a coffeemaker, has a metallic base with an upper exposed surface and an electric heater on its lower side for heating the surface by conduction. A thermostat comprising a plastic-walled packaged unit with an opening through which an internal bimetal sensor is exposed is provided for controlling the heater and is mounted in a depressed niche formed in the surface of the heater. A detachable U-shaped metallic cover covers the opening and includes a heat-conducting projection extending through the opening very closely adjacent the sensor. The thermostat is positioned so that the cover faces and abuts the surface of the niche and a flexible clamp secures the thermostat in the niche and biases the projection and sensor closely together for fast thermostat response. The base may be an aluminum casting with the heater comprising a cast-in circular sheathed electric heating element.Type: GrantFiled: October 10, 1979Date of Patent: December 1, 1981Assignee: General Electric CompanyInventor: Bruce W.
