A connector assembly for installation on a wall includes a main connector body introduced into a cut-out hole of the wall and a protective shell positioned on an inner side of the wall. The protective shell protects the main connector body from an insulation foam entering the main connector body when foamed in place. The protective shell has a front portion, a receptacle formed at the front portion and receiving a second end of the main connector body, a flange extending from and surrounding the receptacle, and a lead-through channel formed at a back portion of the protective shell. The flange is attached on the inner side of the wall and covers the cut-out hole. The lead-through channel has an internal flap routing a cable through the back portion in a meandering manner. The internal flap is inclined with respect to the lead-through channel.

The invention relates to an end hose holder (20) for distributor booms (2) of concrete pumps (1), to a concrete pump (1) with corresponding end hose holder (20) and to a method for assembly thereof. The end hose holder (20) is used for the selective provision of an attachment point for an end hose (6′) and comprises a foot shell coupling (21), which is fastened by way of its foot (23) to a support element (24), for the rotary pipe connection of two concrete line segments (11, 14), the support element (24) having a flange (26) which is configured for the coupling connection to a concrete line segment (11, 14), the relative position of which flange in relation to the foot shell coupling (21) corresponds to a predetermined concrete line segment (11, 14).

A fitting including a housing defining a bore. The bore of the housing at the first open end including a first threaded section, a first annular shoulder located inboard from the first threaded section, and a second annular shoulder located inboard from the first annular shoulder. A grip ring having a plurality of flexible teeth is positioned within the housing and seated against the second annular shoulder, wherein the flexible teeth grip an exterior surface of the pipe or conduit. A bonnet is seated against the first annular shoulder and has an exterior threaded surface that mates with the first threaded section of the bore. A bonnet washer is positioned between the grip ring and the bonnet, and a pair of seal members are positioned between the bonnet washer and the bonnet that sealingly engage with the exterior surface of the pipe or conduit.

A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.

Lock down units and loading arms with lock down units are disclosed. According to one embodiment, a loading arm includes a product delivery pipe pivotally coupled to a product standpipe such that the product delivery pipe is rotatable in a vertical plane. A rocker assembly is coupled to the product delivery pipe. A support arm may be pivotally connected to the product standpipe and slidably coupled to the rocker assembly such that the support arm and the rocker assembly are slidable with respect to one another. The support arm comprises a plurality of slots. A locking pawl is affixed to the rocker assembly and selectively engagable with the slots such that, when the locking pawl is engaged with a slot of the support arm, the locking pawl couples the support arm to the rocker assembly, thereby preventing the product delivery pipe from being raised in the vertical plane.

Apparatus for supporting the lower elbow assembly of a jet pump in a reactor pressure vessel (RPV) of a nuclear reactor are described. The clamp apparatus includes a lower clamp element and an upper clamp element. The upper and lower elements are configured to be positioned at the interface between the thermal sleeve and the jet pump riser elbow. The upper and lower elements include extended ridges that are configured to fit in circumferential grooves precisely machined into the sleeve-elbow assembly on opposing sides of the interface.

A tool and method clean and drain a water heater tank, removing water and sediment from the tank. An insert tube fits through the hot water outlet port to reach the bottom of the tank interior. A fitting connects the insert tube to a hose extending down the outside of the tank to the floor/ground to a drain or container that is lower than the bottom of the tank interior. After priming the tool by using the cold water inlet flow to fill the tool with water and sediment, the cold water inlet is disconnected from the water heater, venting the tank so that water and sediment are siphoned out of the tank through the tool to empty the tank. The tool and method work without unplugging or disconnecting a clogged water heater drain line, without using a compressor or pump, and without creating a wet, messy environment.
