摘要： A pulsation dampener for beverage dispensers and fountain equipment decreases the irregularities in concentrate flow from a single action pump and volumetric dispensing valve combination within a beverage dispenser. The pulsation dampener includes a tube for functionally connecting a pump to a valve, thus providing a flow line between the pump outlet and the valve inlet. The pulsation dampener can also provide a flow line between other beverage equipment functional modules or equipment installed between the pump and the valve. The tube retains and collects concentrate flow from the pump outlet to maintain a minimum fluid pressure on the valve inlet. A retainer around the tube prevents the internal fluid pressure within the tube from exceeding the maximum elongation stress of the tube material. Clamps at each end of the retainer, secure the retainer around the tube. Connectors between the pump and the tube, and between the tube and valve provide a liquid-tight fitting for the pulsation dampener operating in a beverage dispenser or fountain equipment. Material properties of the tube are compatible with the concentrate preventing chemical attack on the tube material. Elastic properties of the tube and the retainer combine to oppose the internal fluid pressure of the concentrate within the tube, thus creating a minimum fluid pressure at the valve inlet.

摘要： A motorless carbonator including a single acting pneumatic water pump connected between a carbonator tank and an uncarbonated water supply with the pump having a gas return spring integral therewith. The pump is driven by the carbon dioxide (CO.sub.2) fed to the carbonator tank. A CO.sub.2 saving device is coupled between the water pump and the carbonator tank and includes a spring biased diaphragm connected to a piston rod and an O-ring support member which operates to control the venting of CO.sub.2 to the atmosphere so as to reduce the amount of CO.sub.2 required to operate the pump during both a pumping stroke and a return stroke.

摘要： A machine for refunding the deposit on empty containers such as bottles or cans for encouraging their return is disclosed. The machine includes an access door through which an empty container is introduced to an inspection station whereupon an inspection device determines if the empty container is marked with a proper identifying mark unique to that brand of container. The inspection device includes an ultraviolet light source which directs ultraviolet radiation onto an identifying mark on the container and causes fluorescent emmission of a narrow band of light. The radiation detection scheme of the present invention employs at least a pair of photodetectors, one which detects the very narrow band of radiation emitted from the fluorescent identifying mark, and the other which monitors whether or not any adjacent light bands are emitted from the object to a significant degree. The presence of adjacent wavelengths of radiation above a predetermined level would indicate that the container was not authentic and would preclude the refund of any money to the person presenting the incorrect container. If the container is determined to be authentic, then the refund is returned and the container is retained by the machine.
