| 5027845 | Coupling with heat fusible actuator member As a coupling is connected, an improved heat fusible actuator member in a plug assembly moves a value member in a socket assembly from a closed position to an open position against the influence of a biasing spring. When the coupling is exposed to excessi... | 07/02/1991 |
| 4932431 | Coupling with heat fusible actuator member As a coupling is connected, an improved heat fusible actuator member in a plug assembly moves a valve member in a socket assembly from a closed position to an open position against the influence of a biasing spring. When the coupling is exposed to excessi... | 06/12/1990 |
| 4926895 | Socket assembly A retainer ring holds parts of a socket assembly against relative movement. The retainer ring is disposed in an outwardly facing groove in a first socket part and an inwardly facing groove in a second socket part. A resilient seal ring is compressed betwe... | 05/22/1990 |
| 4833951 | Tool for mounting a socket The socket of a plug and socket type coupling is mounted with an assembly tool which makes sure that a threaded connection between the socket and a mounting member is properly tightened. When the socket is to be mounted, the socket is operated to a diseng... | 05/30/1989 |
| 4825893 | Socket assembly with fusible element A coupling includes a socket assembly having a locking or retaining assembly which holds a plug in the socket assembly. When the socket assembly is exposed to excessive heat, an element of the retaining assembly starts to fuse and loses its rigidity. The ... | 05/02/1989 |
| 4799512 | Coupling assembly A coupling assembly includes plug and socket assemblies which are formed entirely of metal to enable them to be used at relatively high temperatures.
