Controllable Vehicle For Inspecting Limited Access Areas
US Patent:
4703817, Nov 3, 1987
Filed:
Dec 28, 1984
Appl. No.:
6/687237
Inventors:
Donald R. Stoner - Murrysville PA
Robert D. Senger - Greensburg PA

Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B62D 5702, G21C 1700
US Classification:
180 81
Abstract:
A vehicle and its control system is disclosed for inspecting or servicing a remote limited access location. The vehicle has a drive frame comprised of first and second opposing legs, and third and fourth opposing legs pivotable connected to the first and second legs to form a parallelogram. A drive mechanism is interconnected between the first and second legs of the parallelogram drive frame for opening and closing the drive frame. First and second attachment devices, illustratively in the form of magnets, are also attached to the first and second legs. The vehicle control system taking the form of a programmable computer in an illustrative embodiment of this invention responds to the opening and closing of the drive frame for alternatively actuating and deactuating the first and second attachment devices, whereby the vehicle is controllably driven.
Brazing Sleeve Having Ceramic Flux Band And Method For Applying Same
US Patent:
4624866, Nov 25, 1986
Filed:
Dec 27, 1984
Appl. No.:
6/686941
Inventors:

Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B05D 722, B05D 714
US Classification:
427190
Abstract:
A metal brazing sleeve includes a ceramic flux band formed on the sleeve adjacent an annular recess typically disposed near an open end of the sleeve for receiving a conventional braze preform, by adhering a powder flux to the sleeve by a tacky adhesive and then melting the powder flux in place, by internal heating of the tube. The ceramic flux band is hard and adherent, and resistant to abrasion effects during insertion of the sleeve into a tube, and provides a shadow effect for protecting an optional cemented powder flux band which may be formed on the braze ring.
