Filed:

Jan 26, 2001

Appl. No.:

09/772252

Inventors:

Anthony W. Abraham - Laguna Nigel CA
Joseph G. Raffaelli - La Canada CA
Robert W. Cuomo - Fort Collins CO
Derek Daniel Johnson - Loveland CO
Robert Wayne Lewis - Gardena CA
Eldon Vaughn - Fullerton CA

Assignee:

Robertshaw Controls Company - Richmond VA

International Classification:

G06F 1130

US Classification:

702183

Abstract:

A furnace diagnostic system includes sensors that monitor various functions of the furnace. Data generated by such sensors may be stored for subsequent transfer or may be transferred in real time via an infra red link to a remote handheld device with which an analysis thereof is performed. The handheld device additionally allows the technician to control various furnace functions to facilitate the generation of relevant real time data. In order to further enhance the systems diagnostics capabilities, the communication may be established with a centralized computing facility which includes a data base containing data relating to an entire population of similar furnaces.

US Classification:

285305, 285321, 285276, 285201

Abstract:

A mechanism for attaching a gas controller to a water heater includes a shank that is longitudinally received in a spud attached to the water heater. O-rings serve to form a water tight seal between the interior surface of the spud and the exterior surface of the shank. Slots formed in the spud and a groove formed in the shank allow the two components to be axially locked to one another with the insertion of a retainer spring clip. The spring clip is readily removable to allow the two components to be separated without the destruction of any components.

Assignee:

International Telephone and Telegraph Corporation - New York NY

International Classification:

F23H 512

US Classification:

431 80

Abstract:
