Abstract: A coupling for attachment to air conditioning systems to prevent leakage of refrigerant fluid during testing and servicing thereof. The coupling includes an elongated outer housing adapted to be attached at one end to an air conditioning system. The housing is provided with an axial bore in which is positioned an inner cylindrical body member having longitudinal ducts, which member is movable longitudinally with respect to the outer housing. One end of the inner body member is adapted to be selectively engaged with testing equipment or a refrigerant fluid supply. A portion of the inner housing is aligned with a valve of the air conditioning system which is actuated thereby upon longitudinal movement of the inner body member, thereby permitting refrigerant fluid to flow through the ducts in the inner body member from the refrigerant supply to the air conditioning system. Means carried by the inner body member facilitate longitudinal movement thereof.

Abstract: In the delivery of bulk gasoline to an underground storage tank assurance that the vapor recovery hose is properly connected is provided by sensing of an excess vacuum in the delivery truck tank. Such vacuum occurs when air and/or gasoline vapor is not permitted to replace the gasoline drained from the truck tank. To prevent air from entering the truck tank when the vapor hose is not properly connected to both the truck tank and the storage tank (1) a complete dry break coupling is employed at the vapor hose connection to the underground tank so that vapor cannot be displaced from the storage tank nor can air enter the vapor hose if that connection is not made and (2) a dry break coupling is used only on the truck side of the vapor hose connection to the truck so that air cannot enter the truck tank unless that connection is made.

Abstract: A fabricated adapter valve for mounting on the exterior of a transportation tank for liquid, such as for instance gasoline or oil, providing for coupling with a compatible loading coupler of a loading island, for loading the liquid into the transportation tank. The adapter valve possesses a configuration defined by The American Petroleum Institute for universal coupling with loading couplers of a loading station, and includes a manually operable actuator for opening the poppet of the adapter valve, together with a sinuous-like cam configuration on the actuator for holding the poppet in predetermined open positions.

Abstract: A toy balloon is automatically filled with helium gas using a system responsive to gas pressure. A novel check valve in the neck of the balloon is automatically opened upon insertion of a filling nozzle. The flow of gas to the nozzle from a constant pressure source is initiated by operation of a pushbutton which opens a valve which is resettable as a result of subsequent pressure build-up in the system. Opening of this valve results in opening a pilot valve through which gas flows to the balloon. Opening of the pushbutton operated valve also applies pressure to an expansible chamber of a timer valve through conduit means and when the pressure in such conduit means and in said expansible chamber become sufficiently high after a predetermined time (established to some degree by conditions in the nozzle and check valve) the timer valve is operated to apply gas pressure to an expansible chamber of the pushbutton valve to return it to its closed position thereby interrupting all flow to the balloon.

Abstract: A gas lighter of the type having a tank, a filler valve and a valve head which is biased by a spring to press normally against a seal surface. In order to make sure that there is enough space above the liquid fuel to permit expansion of the fuel a predetermined dimension H is provided above the fuel in the tank. This is accomplished by selecting the length of the filler valve housing to correspond to this dimension H. In addition, the closing movement of the valve head is delayed or retarded by introducing friction into the movement of the valve which permits a portion of the liquid fuel to blow off. The delay device may be determined by force or by the shape of the friction surfaces.

Abstract: A do-it-yourself kit for charging an automobile air conditioning system. A charging hose has a special delivery fitting to be connected first to the charging nipple on the suction side of the compressor of the operating system. Such fitting has a depressor to open the nipple valve and has a check valve to prevent escape of refrigerant by backflow through the hose. The fitting thus isolates the kit from refrigerant pressure. The charging hose also has an inlet fitting for attachment to the nipple of a pressurized refrigerant can, which has a depressor to open the nipple valve. Refrigerant then flows under can pressure to the system. Unused can refrigerant is saved by disconnecting the fittings in reverse order. Since the hose and kit are isolated from system pressure by the check valve, increased safety is obtained and the hose assembly can be made of low-cost materials which can be discarded after use.

Abstract: A tubular nozzle housing having one end secured to a pressurized container supports a reciprocable actuator for selectively actuating a discharge valve on the container when the opposite end of the nozzle housing is threaded to means for receiving the pressured contents of said container.
