US Patent:

42970091, Oct 27, 1981

Filed:

Jan 11, 1980

Appl. No.:

6/111512

Inventors:

Reuben S. Mezrich - Miami FL
Alec Colleoni - New Brunswick NJ
David J. Lyons - Trenton NJ

Assignee:

Technicare Corporation - Solon OH

International Classification:

G03B 2132

US Classification:

352 86

Abstract:

Images and respectively associated timing marks are arrayed, as phototransparencies, about a disk. The disk is rotated and the timing marks are sensed. Display occurs either in two-dimensional fashion, such as in a television system, or in three-dimensional fashion such as in a semitransparent full image projection. Associated logic circuitry determines whether the full 3-D transparency is to be produced, in which case all images on the disk are to be illuminated, or whether swim through will occur, either on an image at a time or on a "ham slice" projection basis.

Abstract:

In one example, a filter cartridge includes a housing having a fluid entry port and a fluid exit port, and the housing has a chamber in fluid communication with the fluid entry port and the fluid exit port. A first medium is disposed within the chamber and includes a material that serves to change the pH of a fluid passing through the first medium. A filtration medium is disposed in the chamber downstream of the first medium and arranged to receive effluent of the first medium. The filtration medium includes a material configured to remove a metal from a fluid passing through the filtration medium.
