Abstract: A probe system primarily for a container containing hazardous chemicals, involving a rinse channel for permanent installation in the bung opening of the container and providing a passageway for a drop tube, and a coupling head installable over the rinse channel and drop tube and providing independent flow connections from each to independent external connections.

Abstract: This invention relates to a pressure/vacuum system apparatus; one part of such apparatus being an economical fitting, another part being operating mechanism, another part being a means to join such fitting to such operating mechanism in a substantially fluid-tight manner, all operable to perform certain functions together without shutting down the pressure/vacuum system they are attached to. Some installations require many fittings. In many instances an operating mechanism may be attached to an operated fitting for only short periods of time and then disconnected therefrom, leaving the operated fitting in (a) a dormant condition in relation to its functions to the pressure/vacuum system, or (b) in a functional condition in relation to the pressure/vacuum system. Thus, in many cases a single operating mechanism may be used for operating each of a number of different fittings from time to time as required.

Abstract: Apparatus is provided for pneumatically communicating with a pressurized cable provided with a peripheral opening. The apparatus includes a saddle of resilient material having a cross-section defined by a parabola and the arc of a circle. The saddle is adapted to sit astride the cable in surrounding relationship with the opening. A pneumatic fitting is molded into the saddle in generally parallel relationship with the cable. The saddle is provided with a bore communicating with the fitting and generally perpendicular thereto. The bore communicates with the opening in the cable. A sealing compound is provided between the saddle and the cable and the saddle is held on the cable by a pair of straps holding a metal strip against the saddle. An orientation protrusion is located on the saddle in alignment with the bore and protruding through an opening provided in the strip.

Abstract: A beer tap rod and tap retainer including a bracket with an apertured lateral extension at its upper end and a clamping ring spaced therebelow for mounting a tap therebetween so that the rod is sleevable therethrough and the clamping ring rotatably interlocked with the neck of a keg to retain the rod and tap thereon and prevent accidental ejection thereof.

Abstract: A method and apparatus for forming pressure plugs in cable systems which are under continuous air pressure while maintaining a continuous air flow through the cable. A supplemental air source is connected to the pressurized cable casing on both sides of the area to be plugged to provide an auxiliary air pressure of sufficient quantity to override the normal pressure in the cable casing. Then, the pressure plug may be installed in the cable while the entire cable, and the selected portion of the cable being plugged, remain under adequate pressure to prevent any moisture from entering into the casing.

Abstract: A low profile port closure apparatus which consists of a port positioned on the vessel to be sealed, a threaded sealing means for effecting fluid-tight closing of said port, and pressure retaining manifold structure which enables sealing positioning and removal of the sealing means in said port, and which manifold means is removable from operative position.

Abstract: A fitting is associated with a closed fluid system for allowing testing by means of a probe, meanwhile insuring the system is maintained in a closed condition. Such fitting has a resilient rubber member one side of which is exposed to the fluid in the system, and the other side of which is exposed to outside the system. The rubber member defines a passage from one side to the other which is held closed by the rubber member mounting means, which compress the rubber member to so close the passage. A testing probe may be pushed into and through this passage, to be exposed to the fluid in the system. The resilient member is in sealing contact with the probe when it is so introduced, and upon removal of the probe, the passage again closes, insuring that the system is continuously in a closed condition.
