Filed:
May 23, 2001
Appl. No.:
09/863614
Inventors:
William Motherway - Boston MA
Assignee:
The Gillette Company - Boston MA
International Classification:
A46D 900
US Classification:
300 17, 300 21, 451 28, 451294, 451357
Abstract:
Methods and devices are provided for end rounding filaments for use on brushes. The devices include an air driven planetary gear system rotating a sanding wheel through a varied elliptical path that attacks the filaments from all sides.

Tufting Oral Brushes
US Patent:
6578929, Jun 17, 2003
Filed:
May 23, 2001
Appl. No.:
09/863193
Inventors:

Joseph Depuydt - Quincy MA
Assignee:
The Gillette Company - Boston MA
International Classification:
A46D 304
US Classification:
300 2, 300 21
Abstract:
Methods and devices are provided for tufting oral brushes. The methods include inserting free ends of continuous strands of filaments into blind holes in a moldbar, at least some of the blind holes having different depths and/or extending at different angles.
High Speed Valve Assembly
US Patent:
7546679, Jun 16, 2009
Filed:
Apr 25, 2006
Appl. No.:
11/411060
Inventors:
William D. Motherway - Boston MA, US
Stuart M. Davis - Norfolk MA, US
Stuart M. Davis - Norfolk MA, US
Assignee:
The Gillette Company - Boston MA
International Classification:
H02K 41/02, H05K 13/04
US Classification:
29743, 137 38, 137 48, 294 641
Abstract:
Apparatus and associated systems or methods include a linear machine with an elongate, axially-slidable core member (i. e. , shaft). In one embodiment, the shaft includes at least one radial aperture to provide fluid (e. g. , air) communication from an interior volume of a winding tube that contains one or more stationary windings, to either end of the shaft through a lumen that extends axially through the length of the shaft. The stationary windings are spaced apart to permit fluid to flow through a plurality of radial apertures in the winding tube. In particular, fluid circulation across the windings may provide sufficient cooling to increase the machine's maximum current rating. The fluid circulation may also provide pneumatic processing capabilities (e. g. , vacuum hold, blow-off). In one exemplary embodiment, the apparatus may be used to insert tube-and-square paper separators into battery casings at high rates.
