Abstract: The subject of this patent application is a door assembly (10) having a knob (38) which, during shipment, is segregated from the rest of the assembly (10) for ease in packaging and storage. The invention includes a unique locking element (62) for securing the knob (38) to the door closure panel (12) when the panel (12) is at a location at which it is to be installed.

Abstract: A double acting positive displacement pump has first and second opposed cylinders, an elongate piston rod connected to cylinder pistons, a plurality of tie rods fastening the cylinders together, spacers on the tie rods and between the cylinders, a control cradle mounted on the tie rods and fixed in position by slots in the spacers, a propellant gas control valve on the cradle, and a valve actuator on the cradle and operatively connected to the piston rod.

Abstract: A spool type fluid control valve having a body, an elongate bore within the body, ports transverse to and into the bore, and a spool with seals reciprocable in the bore has the improvement of a concave seal pocket in an end of the body, a concave seal pocket in a valve cap at the other end of the body, each pocket is of substantially the same diameter as the bore and has a depth sufficient for receiving a shaft seal, a fluid port is formed between the elongate bore and each seal pocket and a toroidal plenum chamber is in communication with and between each fluid port and a fluid conduit through the body.

Abstract: A method of and apparatus for making and dispensing carbonated water; the method has the steps of using carbon dioxide propellant gas at a predetermined propellant pressure for propelling flat water through cooling coils and into a carbonator, pressurizing the carbonator at a predetermined storage pressure which is less than the propellant pressure, exhausting used propellant gas into cooled propellant water, commonly admitting water and exhausted gas into the carbonator while restricting and backing up the flowing propelled water and gas and mixing them together under a pressure above the storage pressure, and storing and dispensing under the storage pressure; flat water may also be selectively diverted and dispensed after cooling and before contact with exhausted propellant gas, and the propellant pressure may be boosted with municipal water pressure; the apparatus has a pneumatically powerable water pump, a carbonator, a propelled water conduit connecting a pump outlet to a carbonator inlet, a fill valve i

Abstract: A multiple flavor post-mix beverage dispensing head has a nozzle, a diluent outlet in the nozzle, a plurality of discrete concentrate outlets in the nozzle, a spout under the nozzle, an outlet from the spout for discharge of beverage from the head, and the improvements of a downward facing open concavity in the center of the nozzle and bounded by a downward facing sharp edge forming the lowest part of the nozzle, a convex bottom nozzle surface extending upwardly from the concavity sharp edge, a sharp edged and squared counterbore between the convex bottom nozzle surface and a restrictor bore in each of the concentrate outlets, sharp edges on all surface intersections on the nozzle bottom surface and rounded intersections between all surfaces in the interior of the spout, an included angle between the bottom surface of the nozzle and inner surface of the spout which is divergent toward the centerline of the spout and which turns into the spout outlet, and a toroidal diluent flooding chamber between the nozzle

Abstract: A carbonator has a pressure vessel, a nozzle for introducing water and carbon dioxide into the vessel, a water level control including a reed switch and a magnetic float for sensing the level of water and operating the reed switch; a novel housing encloses the level control and provides a unidirectional fluidically affected delay in sensing and control response to a rising water level during filling of the carbonator; the housing has a water chamber which encloses the level sensing float, a water inlet into the water chamber near the level of a maximum desired water level in the vessel, a water outlet from the bottom of the water chamber, and a check valve in the water outlet for allowing flow of water out of the water chamber and for precluding flow of water into the water chamber from the water outlet.
