US Patent:

44261535, Jan 17, 1984

Filed:

Sep 16, 1982

Appl. No.:

6/419104

Inventors:

Edwin L. Libby - Longmont CO
Randall A. Maddox - Lexington KY
Douglas J. Roberts - Longmont CO

Assignee:

IBM Corporation - Armonk NY

International Classification:

G03G 1500

US Classification:

355 3R

Abstract:

Image transferring apparatus for a continuously variable reduction electrostatic copier. A single fixed aperture is employed, adjacent the object plane, to: (1) reduce image intensity variations caused by non-uniform illumination across the object plane; (2) correct for lens cos. sup. 4 losses for one mode of reduction; (3) reduce image distortions due to photoconductor drum curvature, particularly at edges; and (4) reduce image illuminance variations due to changes in reduction mode throughout a continuous range of reduction modes. In accordance with preferred embodiments, the foregoing functions are achieved notwithstanding movement in image or optical center line as a function of reduction to compensate for corner referencing objects to be copied. The single fixed aperture provides for adequate reduction in intensity variations, i. e. , in an embodiment of the invention, image intensity varies plus or minus 6% from nominal levels across the image plane as reduction mode is varied throughout the range of reduction modes.

International Classification:

C03B 913

US Classification:

65241

Abstract:

An I. S. machine is disclosed which has a plurality of individual sections arranged in side by side relation. Each section has blank mold and blow mold opening and closing mechanisms and an invert and neck ring holder mechanism for transferring a parison between these mechanisms. Each of the mold opening and closing mechanisms has a pair of opposed mold support mechanisms which are supported for linear displacement. Ways at either end of the section support one end of each pair of mold support mechanisms and the other end is supported on a pair of shafts located between the mechanisms. One of these shafts is supported between the spaced vertical supports of the invert and neck ring holder mechanism and the other shaft has a first part supported between one of the spaced vertical supports and the vertical invert housing and a second part is supported between the other one of the spaced vertical supports and the vertical invert housing.
