Appl. No.:

10/147595

Inventors:

William P. Dowst - Reading MA
Edward J. Mangan - Southborough MA
Roy Nicoll - Berkshire, GB

Assignee:

Berol Corporation - Freeport IL

International Classification:

B43K 700

US Classification:

401209, 401 6, 401207, 401214, 401216

Abstract:

A writing instrument having an elongated barrel comprised of an outer portion and an inner portion, rotatable relative one to the other. The point or writing tip is fixed to the barrel inner portion, disposed at an angle to, and may be offset from, the centerline of the barrel outer portion. The barrel inner portion is caused to rotate and move axially relative to the barrel outer portion by pressure on the writing instrument, or weights attached to the barrel inner portion, to bring the point into desired alignment during the writing process. Further pressure on the point or writing tip causes the barrel inner portion to move to a rearwardmost position at which rotation of the point or writing tip is impeded by a gripping structure.

US Classification:

431112

Abstract:

An incandescent gas mantle assembly includes a metal coupling member and a mantle supporting sleeve member of thermally resistant material that has a skirt portion to which a metal oxide mantle sock is secured in depending relation. The metal coupling member has a body portion of disc configuration with an outer periphery and an inner periphery, a plurality of inwardly extending first coupling portions integral with and spaced about the body portion for attachment to a cooperating burner head, and a plurality of second coupling portions integral with and spaced about the body portion, the second coupling portions being in coupling engagement with recess structure of the mantle supporting sleeve member.

Inventors:

William P. Dowst - Reading MA

Assignee:

The Gillette Company - Boston MA

International Classification:

G06K 946

US Classification:

382112

Abstract:

A method of analyzing the writing quality of a ball point pen for ink laydown, blobbing, and degree of inconsistency employs a computer and an image analysis software package capable of assembling a pixel gray level distribution known as a histogram. The distribution of pixel gray value for a writing sample is manipulated and analyzed, the values then being compared to a range of pre-established values.
