Assignee:

American Standard International Inc. - New York NY

International Classification:

H04L 12/403
H04L 12/56
H04L 12/43

US Classification:

370451, 370392, 370461

International Classification:

F04D 17/08

US Classification:

Abstract:

To protect the bearings, lubricant and seals of a refrigerant compressor, the compressor includes one or more inductors for mitigating a high frequency common mode current that produces a high frequency shaft voltage. Each inductor is a ring of magnetic material encircling three insulated cables that convey three-phase power from an adjustable frequency drive to the compressor's motor. Without the inductors, the high frequency shaft voltage can become damagingly high due to the length of a cast iron housing that can be particularly long if the housing contains both a motor and several centrifugal impellers. The high frequency shaft voltage is just one component of a composite adverse shaft voltage. Another component, known as an operationally induced shaft voltage, can be reduced by a grounding contact, so instead of using just an inductor or just a contact, both can be used to provide a total solution to the problem.

Appl. No.:

13/934775

Inventors:

Addric E. Bassham - Polk City FL, US
Douglas F. Kinninger - Lithia FL, US
Craig T. Price - Winter Haven FL, US
Robert L. Swanson - Windermere FL, US

International Classification:

B32B 37/00

US Classification:

156182

Abstract:

An inflatable or gas-filled insulation panel comprises an envelope having two outer sheets sealed together along edges of the sheets and at least one of the sheets has an outer reflective surface. The envelope encases a plurality of internal films that include a polymeric film having a plurality of reflective stripes disposed thereon and spaced apart on the films. Seals are formed along the gaps or areas between the reflective stripes on the films by application of heat and pressure, which causes the films to seal to each other and the outer sheets at spaced apart intervals. A channel is formed between the outer edges of the films and the outer sheets, and a valve, disposed at an end of the panel, is in fluid communication with the channel for the injection of a fluid, such as an inert gas or air, to inflate panel.

International Classification:

F24F 700
F24F 1304

US Classification:

454327

Abstract:

A device for monitoring and modulating the admission of fresh air into a building. The device comprises a housing; a sensor associated with the housing and operable to measure airflow through the housing; and a damper including at least two damper blades. Each damper blade includes a shaft rotatably attached to the housing at least at a first shaft end. The shaft is located on the surface of the damper blade so as to divide the surface into first and second substantially equal areas.
