Abstract: A water purifier for treating water intended for drinking and like purposes, for installation at point-of-use, i.e., home, office or workplace, which is effective in removing additional contaminents therefrom using a heated carbon filter and distillation, in which the water being purified is heated and induced to alternately flow back and forth between an open compartment used for the filter and a closed evaporator in which it is distilled, the intervals of flow into the filter compartment being effective to heat the filter to thereby increase its ability to remove heavy molecular pollutants (e.g., pesticides, herbicides, etc.) and also being an advantageous location from which there is released to atmosphere low molecular volatile pollutants (e.g.

Abstract: In relation to a primary end use in nuclear medicine, namely, the recording of multiple images in a so-called dynamic study of a patient using a gamma camera wherein said multiple images are typically photographically reproduced on a single sheet of film in an appropriate format, the within inventive method obviates the need to modify the angular orientation of the images projected onto the image-receiving film sheet incident to providing same with the proper format or display position, and instead contemplates the novel alternative of properly pre-positioning the film sheets. Among other advantages and benefits is a noteworthy simplification in the construction and operational requirements of the image-projecting lens assembly of the apparatus being used to produce the photographic record.

Abstract: An apparatus of generally known classification which produces photographic records of multiple images in various display formats, i.e. a four-frame, six-frame, or other such multiple frame format arrangement of the images, wherein positional movements in the lens assembly typically used to project the image onto the film sheet is relied on to correspondingly position the image on said film sheet is herein significantly changed and, instead, the projected image is positioned by selection of an appropriately pre-positioned lens. Thus, instead of using one universally movable lens, a multiple of differently strategically positioned lenses are operationally available and are separately selected for operation based on position to correspondingly provide an appropriately positioned image on the photographic record or film sheet.
