Abstract: Described herein is a multi-user retail photo kiosk system that includes multiple touch screen and Graphic User Interface (GUI) controlled consumer photo editing, photo print and product selection, and photo order placement terminals and multiple photo printers. The user photo kiosk terminals can receive images. Billing and payment is accomplished using barcoded receipts provided at the user terminal for payments for purchased photo products. A printer array incorporating various printers capable of producing prints or various sizes and formats can be configured as a horizontal counter or as a vertical tower and includes means to alert the user that their photo print order is complete. In addition, the system automatically notifies operators if equipment service, maintenance, media refilling, and/or post printing finishing procedures are required.

Abstract: A pump includes a piston rod and precision bearings that eliminate radial movement of the piston rod while permitting reciprocal axial translation. A piston extends axially from the piston rod, and is received in a cylinder in a pump head. A static seal assembly includes an annular ring received about the piston in a leakproof sliding engagement, the ring being formed of a soft polymer material. The annular ring is encapsulated in an outer ring formed of a stiff plastic material, defining a self-contained seal cartridge. The outer ring is dimensioned to be received in the pump head in a cylindrical recess that permits radial freedom relative to the axis of the cylinder. To assemble the pump, the seal cartridge is first assembled to the piston, thus assuring that the seal is aligned with the piston. Thereafter, the head is assembled to the pump body, the piston being inserted in the cylinder and the seal cartridge being received with clearance in the recess.

Abstract: A hydraulic pulse dampener has two diaphragms, each positioned opposite a recess formed in the housing. The regions between the diaphragms and the associated recesses are sealed from the fluid which flows through the dampener so that a rise in pressure in the fluid may cause each diaphragm to flex towards the recess behind until it may completely nest in it. The diaphragms are designed differently so that they will begin to flex and take a completely nested position in different pressure ranges.

Abstract: A hydraulic pulse dampener of liquid compressibility type has a flexible tubing wound around a form within a liquid-tight housing filled with a compressibility liquid and a stiff diaphragm placed adjacent a recess formed in a receiving member. As the fluid flowing inside the tubing experiences pressure pulses, the walls of the tubing expand and transmit the pulse energy through the compressibility liquid and causes the diaphragm to gradually flex towards the recess until it may completely nest in it. The recess in the receiving member preferably has a central flat portion so that the flexing diaphragm will first contact the receiving member at the center and the nesting will spread outwardly therefrom.
