Disclosed is an improved serial impact printer which both prints and serrates a document. The printer includes a print wheel which is rotated to position a selected character in front of an anvil. The print wheel includes a wheel-like circular member having print characters at the end of fingers which extend from the top of the print wheel's perimeter. An impact mechanism pressures the selected print character against the anvil, the document being positioned between the selected print character and impact mechanism. The impact mechanism includes a d.c. motor which turns a threaded shaft which is engaged with a threaded hole in the end of a hammer. Counterclockwise motion of the d.c. motor advances the hammer's head to pressure the back of the print character against the anvil, thereby printing and serrating the document with the selected character. Thereafter, clockwise motion of the d.c. motor restores the impact mechanism to its original position.

Process and apparatus for disinfection of hydrophilic contact lenses by controlled exposure of the lenses to heat. In the apparatus is a compartment formed by a heat storage-transfer combination. The compartment forming combination is heated by means of a heating element. The heat is transferred to a contact lens carrying case received in the compartment. The heat is maintained at temperatures and for a period of time sufficient to disinfect hydrophilic contact lenses contained in the carrying case.

Apparatus for disinfection of hydrophilic contact lenses

A combination comprising a push button switch or other switching means disposed in a cover of a contact lens disinfecting apparatus whereby the switching means can actuate the heating means included in the apparatus only when the cover of the apparatus is in a completely closed position.

Manual switching means for contact lens disinfecting apparatus

A carrying case includes first and second contact lens liquid storage chambers which are located on separate axes and have openings which are inverted one from the other. Each respective storage chamber has a plurality of threads for engagement with a compatible set of threads on each removable cap said caps being provided with a seal to promote integrity between the mating parts. Each cap has a convex base for receiving the concave surface of a contact lens and a concave cover pivotally supported to open and close immediately over the convex base to encapsulate the contact lens in the area defined between the convex base and the concave cover.
