    Abstract: A page turner device for an open book comprises a support for the book, and a power driven disc configured to rest on the top of the pages of such open book. When the power drive is energized, the disc will start to rotate while in contact with the open pages. The disc has a finger portion which protrudes outwardly from adjacent portions of the disc, and a page curler drive is used for creating a curl or arch in the center portions of an open page, so that when the finger rotates to the proper position, it will go into the recess under the curl, and as it continues to rotate, the finger will pull the page with it. When the disc comes to a rest position, the finger will have completely opened the subsequent page. At the rest position a cam operates a switch to disable the power drive until such time as the person reading again initiates a manual switch to commence the page turning sequence.

    Abstract: An optical switch and attenuator in which any waveguide in an input waveguide bundle may be selectively optically aligned or misaligned with any waveguide in an output waveguide bundle. The waveguide bundles are attached to beams that translate the bundles through non-parallel arcs. The device provides high-performance switching and attenuation of any number of input and output waveguides.

    Abstract: A filter cartridge end-of-life mechanism and a filter cartridge assembly for a water treatment device. The end-of-life mechanism comprises a float which is moved along an escapement path each time the device is filled. A counting mechanism connected to the float provides a continuous visual indication of the amount of useful life remaining in the filter cartridge. The cartridge assembly includes a tray detachably connected to a filter cartridge. The tray is positioned beneath the outlet end of the cartridge to remove water treatment particles from the treated water.

    Abstract: An apparatus for use with a water treatment unit that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member as water fills and drains from the chamber, the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.
