Abstract: An automatically operated soap dispenser for use in washing the hands of a user is provided in a housing. Enclosed in an intermediate portion of the housing is a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof. Residing in the upper portion of the housing is a disposable liquid soap container having extending from the bottom thereof a resilient elongated tubular member with a self-sealing nipple valve on the lower end thereof which is positioned in the opening on the upper wall of the cylindrical chamber. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of liquid soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the open front of the cylindrical chamber.

Abstract: An automatically operated soap dispenser and hand dryer are provided in a single housing. The housing encloses a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof opposite which a self-sealing nipple valve on the end of a tubular member of a disposable liquid soap container resides. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the cylindrical chamber The automatic hand dryer located in the housing below the cylindrical chamber provides for automatically discharging warm air through an outlet thereof in response to the hands of the user being positioned adjacent thereto.

Abstract: A bouyant hanger unit comprises an elongated body molded of plastic to provide a clip on the bottom end thereof for holding a dental film chip in the plane of the hanger unit. The hanger unit has a circular projection on one face thereof axially aligned with a circular recess on the opposite face thereof. Such a construction enables a plurality of hanger units to be assembled face-to-face while permitting any of the hanger units to be pivoted away from the remaining hanger units in the assembly for the purpose of examining the dental film chip clipped on the bottom thereof. When the individual hanger units or an assembly of the hanger units with dental film chips clipped on the bottom thereof are placed in a solution they float in an upright position with the upper end thereof extending above the surface of the solution.
