Abstract: The invention relates to a swivel-type coupling device enabling relative rotation between heating fluid conveying conduits of a domestic heating radiator unit connected thereto. The swivel-type coupling device comprises: a first cup-shaped member having an axial bore extending therethrough and being connectable to a first heating fluid conveying conduit, a second cup-shaped member having an axial bore extending therethrough and being connectable to a second heating fluid conveying conduit.

Each pair of a first rotating fluid line and the corresponding first static fluid line are fluidly coupled and each pair of a second rotating fluid line and the corresponding second static fluid line are fluidly coupled. Hydraulic fluid is transferable between each static fluid line and the corresponding rotating fluid line.

Abstract: A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupled mechanically in series between the extension pipe and the housing of the flexible pipe joint, and the flex element at the outer radius is coupled mechanically in parallel with the series combination of the inner flex elements. The inner flex elements isolate the flex element at the outer radius from transport fluid, and the flex element at the outer radius reduces the axial compression of the inner flex elements. Thus, the inner flex elements may have a reduced radius and a different composition to handle a higher loading of heat and pressure.

Abstract: A conduit structure provided with a rotation coupling comprises a first hose part (1) with a first coupling part (4) at an end thereof, and furthermore a second coupling part (5) at an end of a further part (6, 15; 2, 4, 19).

The first hose part (1) extends through and some distance beyond the first coupling part (4) and in the coupled condition the sealing element (9) seals the space between the portion of the first hose part that extends beyond the first coupling part and the second coupling part (5).

Abstract: An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The joint may be a ball joint, a coaxial joint or an external sleeve. The sleeve is positioned surrounding the conduit. The sleeve may have a hexagonal outer surface and rotates freely about the conduit to prevent torque from being applied to the conduit.

Abstract: A swivel misalignment coupling for connecting pipe sections in a high-pressure conduit. In one embodiment, the coupling is a three-bolt coupling having a female coupling member, a male coupling member, and a swiveling collar member. The male and female coupling members have contact surfaces that are spherical to enable sealing contact between them. A seal ring may be positioned between the contact surfaces to ensure a good seal. The collar swivels around the male coupling member to facilitate fastening of the collar to the female coupling member, which holds the male and female coupling members in sealing engagement. Recesses may be positioned radially inward from the attachment points (e.g., bolt holes) of the female coupling member to reduce stress and potential deformation of the contact surface.

Abstract: A flexible, sectioned plastic arm for a showerhead comprises a series of interconnected ball-and-socket (B&S) sections (10) with a proximal (shower pipe) end piece (12) and a distal (showerhead) end piece (14). Each B&S section has a proximal (cup or socket) end (10S) and a distal (ball) end (10B). The proximal end piece has a proximal end with female threads which can be screwed onto a shower pipe and a ball-shaped distal end for snapping into the socket of the most proximal section of the shower arm. The distal end piece has a proximal end with a socket for snapping onto the most distal end section of the shower arm and a distal end with male threads (12T) which can be screwed onto the showerhead. The arm has a through hole containing a series or chain of cylindrical brass or other metal sections, tubes, or sleeves (16). These prevent the arm from being bent too far, thereby to keep the B&S from separating.
