Abstract: Methods are provided for automatic cleaning of gripper belts and rollers within a self-service dispensing device. In an embodiment, a cleaning station located in a storage bin of the dispensing device is used to perform the automatic cleaning. The cleaning station is retrofitted into an existing storage bin of the dispensing device. In another embodiment, an interactive slot mechanism of the dispensing device is modified to hold a cleaning case and provide cleaning fluid to clean the belts and/or rollers. In another embodiment, a cleaning case contains a reservoir of cleaning fluid and a pad saturated with the cleaning fluid to clean the internal belts and roller. Furthermore the cleaning case may contain an automatic lid to maintain saturation of the pads and to keep debris from the cleaning case itself.

Abstract: A valve assembly is provided that is suitable for use as an air release valve. The valve mechanism is actuated by liquid forced through an orifice by a diaphragm under pressure from the main discharge and is less prone to valve chatter under varying pressure conditions. The use of an externally adjustable orifice and/or regulator allows the valve assembly to operate satisfactorily in a wide range of pressures. The mode of operation of the valve mechanism is externally visible.

Abstract: A book support system (10) is provided to allow manual holding and reading of book (12) in one hand of a user. The book support system (10) includes a housing (18) having a recess (20) formed therein. The recess (20) is of predetermined contour and is adapted for insert and receipt of the book (12). A releasable constrainment mechanism (56) including orthogonally directed first and second resilient members (58 and 60) are included to constrain the book (12) within the recess (20). The releasable constrainment mechanism (56) is secured to the housing (18) and a tab member (48) is provided in a lower section of the housing (18) to allow the user to hold the book support system (10) in one hand while reading.
