International Classification:

B24B 4900

US Classification:

451 5, 451390, 451538, 451527

Abstract:

A retainer for retaining an abrasive pad on a lens making machine and an abrasive pad adapted to such retention comprises a retainer nestable with a lap of a lens making machine wherein when such retainer is nested, a pad placed upon said lap before nesting will be trapped in the desired position. The pad of the invention includes radially outwardly extending members beyond the working area of the pad whose purpose is to be trapped by the retainer. The invention enables automatic loading and unloading of pads on the lens making machine.

Filed:

Apr 29, 2009

Appl. No.:

12/431856

Inventors:

Douglas J. Roberts - Willington CT, US
George R. Rowland - Winsted CT, US

Assignee:

Westinghouse Electric Company LLC - Cranberry Township PA

International Classification:

G01N 9/24
G01N 29/26
G01N 29/265

US Classification:

73622, 73637

Abstract:

A non-destructive examination pipe scanner that employs a main carriage on which a sensor is mounted, a tensioner carriage and an idler carriage. The main carriage and the tensioner carriage are positioned around the pipe at spaced locations and connected on either side by a spring band. The idler carriage is slidably supported by the spring band in between the main carriage and the tensioner carriage. The sensor on the main carriage collects data about a circumferential weld on the pipe as the main carriage drives the tensioner carriage and the idler carriage around the circumference. The tensioner carriage has a variable length connection that adjusts the tension on the spring band to urge the main carriage, idler carriage and tensioner carriage into contact with the surface of the pipe.

Inventors:

Douglas J. Roberts - Willington CT, US

Assignee:

Westinghouse Electric Company LLC - Cranberry Township PA

International Classification:

G01N 19/00

US Classification:

738658

Abstract:

A pipe scanner for non-destructively scanning an extended length of the circumference of a pipe along an axial dimension. The pipe scanner includes a collar sized to fit around the outer circumference of the pipe. Wheels supported on the collar ride on the surface of the pipe while maintaining a space between the inner surface of the collar and the outer surface of the pipe. A track extends circumferentially around the collar for guiding a circumferential drive unit that rides on the track and carries a non-destructive sensor for monitoring the surface of the pipe as the circumferential drive unit moves around the track. An axial drive unit is connected to the collar, having a plurality of circumferentially spaced drive wheels in contact with the pipe for moving the collar along the extended length.

International Classification:

C03B 900

US Classification:

65359

Abstract:

A mold opening and closing mechanism for an I. S. machine has a pair of opposed mold support mechanisms for carrying at least one opposed pair of mold side portions. Each mold support mechanism includes a yoke having a first vertical bore and a second horizontal bore. Molds are carried by upper and lower inserts which also have a hole extending vertically therethrough. An insert carrier is linearly displaceable between retracted and advanced positions and the inserts and the yoke are secured to the carrier by a first pin slidably extending vertically through the vertical holes in the inserts and yoke, and through a vertical hole in the carrier. A second pin slidably extends through this yoke horizontal hole and the drive assembly is connected to this second pin.
