US Patent:

RE308781, Mar 9, 1982

Filed:

Apr 6, 1981

Appl. No.:

6/251574

Inventors:

William G. Wakeman - San Jose CA

Assignee:

Pitney Bowes Inc. - Stamford CT

International Classification:

G03B 2762

US Classification:

355 75

Abstract:

In an electrophotographic copying apparatus, a cover and document keep device comprises a rigid cover member for securely holding original documents during copying and for effectively shielding the user from exposure to ultraviolet or visible radiation. A support member incorporating a plurality of positioning rods is vertically slidingly engaged within holes formed in the copying apparatus housing. An L-shaped frame is hinged by a first hinging means to the vertically movable support member, and carries the rigid cover by an additional second hinging means. Fastening means are provided to allow only one of the hinging means to be operated at one time, thereby allowing the rigid cover member to be pivoted about either axis defined by the hinging means. Accommodation of various original document thicknesses is provided by vertical sliding movement of the support member.

Appl. No.:

7/258620

Inventors:

Clyde C. Shaw - Redwood City CA
William G. Wakeman - San Jose CA
John H. Orio - San Jose CA

Assignee:

Anent Systems Corporation - Mesa AZ

International Classification:

G01L 708
G01L 910

US Classification:

73728

Abstract:

A Hall effect pressure transducer incorporates a pressure-deflection diaphragm which has patterned depressions therein to enhance linearity of response; an O-ring diaphragm seal which seals the diaphragm against pressure leaks without affecting the linearity of response; a pair of magnets, preferably rectangular, oriented with their North-South axes oppositely parallel, and oriented transverse to the deflection axis of the diaphragm to provide a uniform magnetic field gradient and sensitive, accurate, linear response of the transducer to either positive or negative pressure-induced deflections of the diaphragm.
