4099864, Jul 11, 1978
Filed:
Mar 11, 1977
Appl. No.:
5/776875
Inventors:
Patrick J. Gilligan - Minneapolis MN
Kenneth D. Schrupp - Minneapolis MN
Assignee:
Pako Corporation - Minneapolis MN
International Classification:
G03B 2754
G03B 2776
US Classification:
355 37
Abstract:
An improved light source for a photographic printer uses a plurality of print lamps. A heatsink and blower dissipate heat generated by the print lamps. The light diffuser which diffuses light from the lamp includes a white porcelain diffuse reflector.

Automatic Density Control

US Patent:
4017179, Apr 12, 1977
Filed:
Sep 4, 1975
Appl. No.:
5/610188
Inventors:
John Pone - Minneapolis MN
Kenneth B. Schrupp - Minneapolis MN
Patrick J. Gilligan - Minneapolis MN
Ronald B. Harvey - Minneapolis MN
Gerald A. Jensen - Wayzata MN
Assignee:
Pako Corporation - Minneapolis MN
International Classification:
G03B 2774
G03B 2778
US Classification:
355 68
Abstract:
An automatic density control device for photographic printers for sensing and correcting for a "subject failure" in a photographic negative, where the subject area of the negative is out of the optimum density ratio to the background area, which device includes a frusto-pyramidal radiation directing member having its enlarged end proximate to the negative and its small end remote therefrom and being positioned to receive the radiation from a source through the negative and having subject sensing means mounted at the central portion of the enlarged proximate end of said member to sense the radiation passing through the central subject area of the negative and also having background sensing means mounted at the diminished remote end to sense the radiation passing through the marginal portions of the negative and the marginal portions of the enlarged end of said member and including circuitry for comparing the signals produced by said subject sensing means and background sensing means and thus deriving a density signal which is used to control the exposure time during the printing process.
