Abstract: A chemical delivery system connects to a chemical tank and includes a union connected to the tank outlet and providing an antirotation feature, in addition to threads, to prevent rotation of the assembly in response to asymmetric loads. A measuring tube alternately receives liquid from the tank and is isolated from the tank. While isolated from the tank, liquid is withdrawn from the tube by a pump under conditions allowing the pump to be calibrated. The assembly is cantilevered from the tank outlet and is of reduced length and weight producing a device which is not prone to overstress the tank outlet.

Abstract: A device is provided for allowing a conduit to extend through a wall while providing a seal around the conduit. The conduit extends through an opening formed in the wall and the conduit has a first end, a second end, and a central axis extending within the cavity of the conduit and along its length. First and second protrusions of the first end of the conduit are shaped to be received through first and second slots of the opening formed through the wall. A resilient seal member is attached to the first end of the conduit and is compressible by moving the conduit out of a first position relative to the opening in which the first and second protrusions are aligned with the first and second slots. By moving the conduit away from its first position, the resilient seal member is compressed to provide a liquid seal which prevents liquid from leaking through the opening formed through the wall.

Abstract: A vapor vent valve has an annular locking ring received thereover, with surfaces thereon engaging the valve for limited axial movement therebetween and preventing relative rotation therebetween. A fuel tank has an access opening with a slit formed therein.

The valve, locking ring and a seal ring may be pre-assembled to form a subassembly capable of being installed and locked on the fuel tank as a unit without the need for tools or fasteners.

Abstract: A connection fitting for the fastening of elongated bodies, for example of cables (2) or also hoses, tubes, corrugated hoses and the like, in an opening (3), which can be a through hole or a boring in a wall (4) of a building. The connection fitting includes a clamping collet (9) which, in its operation position, penetrates the opening (3) and is self expanding behind the opening (3), and which, by means of an axial retraction opposite to the direction of insertion, is also radially compressible and thus exerts a clamping force on the elongated body. To effect this motion of retraction, a sheath (11) is provided, which is frictionally connected or force-fit connected with a locking ring (15), which, by rotational movement of the sheath (11) itself turns accordingly and, by its own threading, is axially displaced until the ring (15) abuts the wall (4) on the opening rim (12) and remains there in a stop position. In this way, the respective thickness of the wall (4) is accommodated.

Abstract: A heat shield for high thermal loading and particularly pulse heat loading n fusion reactors e.g. as first wall, plasma physics installations, particle accelerators, etc. contains a cooled support plate carrying a large number of shielding or limiter members on its side facing a heat source, e.g. a hot plasma. The shielding or limiter members are detachably connected to the support plate by a good thermally conducting seat, e.g. a bevel, ball or flat seat. By suitably shaping and arranging the limiter members, it is possible to substantially cover the surfaces of practically any desired shape such as, e.g., the inner wall of a toroidal vacuum vessel. As a result of their limited size, the limiter members can be adapted in a optimum manner to locally differing requirements. The size and shape of the support member can be adapted to widely differing boundary conditions.
