Abstract: There is provided an improved carbonated drink dispensing system including a semi-rigid plastic collapsible bladder which holds the carbonated beverage and a dispensing apparatus which receives the semi-rigid bladder. The bladder includes a plurality of ribs to provide additional strength. The dispensing apparatus and bladder are generally cylindrical in shape. The dispensing apparatus includes a top pressure plate for applying downward pressure to the top of the bladder as the beverage is dispensed thereby collapsing a portion of the bladder so as to keep appropriate pressure within the bag thus preventing the escape of carbonation from the beverage. A gearing mechanism to provide a mechanical advantage is utilized in connection with the movement of the pressure plate.

Abstract: Couplers for hand tools and extension handles are made up of two one piece fittings. Each fitting has an attachment element for connection to one of the tool and extension handle and a connecting element for joining the two fittings. Normally, one of the attachment elements will be a threaded male element and the other a threaded female element. The connector elements also are composed of a male and female element. The male connector element is a tube or rod with a dually tapered flange. The flange fits into a channel (depression) in the female connector element. The connecting elements are complementary in shape and size.
