Abstract:
A gas outlet system (30) that includes first indexing structure (63, 68) mating with a first adaptor (11) for releasably connecting the first adaptor (11) to the outlet (30), and a second indexing structure (55, 68) mating with a second adaptor (21) for releasably connecting the second adaptor (21) to the outlet (30). The gas outlet system (30) includes an engaging member (84, 70) for engaging the adaptor (11, 21) to the outlet (30) and includes first (26) and second (35) urging members each independently operable to disengage the engaging member (84, 70) to release the adaptor (11, 21).
Abstract:
A penetration unit (10) for a concrete slab including a hollow housing (28) open at one end for receiving a service line or pipe (27), and provided at its other end with an elarged opening surrounded by an annular flange (36) which enables connection of the housing (28) to formwork (37) defining the boundary of the concrete slab. The housing (28) defines a hollow space (29) in which the service line or pipe terminates and may be connected to a further line or pipe such as an elbow (31). A puddle flange (32) may be located about the service line or pipe (27) and engage the housing (28). Intumescent material may be located in the hollow space surrounding the pipe or line (27).
Abstract:
A screw (10) with an unthreaded spaced away radial flange portion (21) on its shank may be tightened and released within a bore (12) without falling from the bore (12) once released. The assembly of the screw (10) and a strain relief bushing permits the conventional strain relief bushing (11) to optionally hold and release cable without risking the loss of the retaining screw (10) from the bushing (11).
Abstract:
A fire-stop stack fitting (34) includes a cylindrically-shaped coupling wall (36) having a stop (52) therein for receiving pipes to be coupled from first and second ends. The first end of the cylindrically-shaped coupling wall is affixed to a cavity forming wall (42) defining a cavity which is open in an inwardly radial direction and in a first-end axial direction but which is closed in an outwardly radial direction and in a second-end axial direction. An attachment flange (46) is affixed to the first end of the cavity-forming wall for attaching the fire-stop stack fitting to a concrete form (50). An intumescent material (44) is placed in an intumescent-material cavity (62) and the flange of the fire-stop stack fitting is fastened to a concrete form wall. After concrete (56) has hardened and the form wall (50) is removed, pipes (38, 40) are inserted in opposite ends of the cylindrically-shaped wall (36). The intumescent-material is quickly heated by fire on the first side of the wall since the intumescent-material cavity is open to that side and the intumescent material is free to expand radially into the pipe (40) inserted into the first end of the fitting.
Abstract:
A receptacle (10) for installation in exterior walls (8) of a building for removable installation of a freeze resistant hose bib (32) is shown. The receptacle (10) comprises a tubular element (20) having at one end means (22) (23) to receive and hold a threaded water supply pipe nipple (30) in a clamping relationship with the threaded nipple end (30) thereof inserted axially into the interior of the tube (20), and at the other end thereof a mounting block means (12) adapted to be secured to exterior wall surface (8) of a building. The tubular element (20) extends into the wall (8) and is adapted to receive through said block (12) after installation in the wall (8) a freeze resistant hose bib (32). The receptacle (10) is fastened to the exterior wall surface (8) and clamps the water supply pipe (28) permitting subsequent installation and removal of a freeze resistant hose bib (32) for servicing.
Abstract:
The invention refers to an arrangement for the leading-in of a pipe (17) through a recess (16) in walls (18) or vaults in buildings with the help of a case (1) enclosing the pipe (17). The case (1) is extended along the recess (16), and has at least at a first end a thread (2) and is at least at the mentioned first end furnished with a detachable screwed-on collar (6, 6') for the fixation of the case (1) to the wall (18). The collar (6, 6') has a collar ring (10, 10') with a hole (11, 11') through which the pipe (17) is extended and whose diameter is essentially in accordance with the pipe (17). The case (1) is elastic and less stiff than the collar (6, 6').
Abstract:
There is disclosed a duct adapted to extend through an aperture (b) in a wall or partition (W) and comprising a sleeve (10) and outwardly extending flanges (12) adapted to overlie the opposed outer surfaces of the wall or partition at the opposite ends of the sleeve, at least one of said flanges being adapted to be pushed onto an end of the sleeve to lockingly engage same.
Abstract:
Various constructions of prefabricated sleeve are described for fitting round pipes which are to have brickwork or foundation work in concrete made round the pipe. The sleeve acts to hold the mortar/concrete away from the pipe (12) until it has set, so leaving, after the disintegration of at least components (10) of the sleeve between the outside of the pipe and the outside of the sleeve (2), a hollow void round the pipe, as required by the building regulations. The sleeve may be made of inexpensive materials which can biodegrade in situ, thus avoiding the need to remove them by hand after the mortar/concrete has set. Sleeves may be supplied preassembled, or may be constructed on site, e.g. by folding from a waterproof surfaced fibreboard blank.
Abstract:
The disadvantages of existing cover surrounds for wall-mounted bathroom fittings are avoided by the invention by virtue of the fact that the cover surround comprises an inner supporting plate (10) fastened to the wall (7) and an outer cover plate (11). The inner supporting plate (10) is preferably designed to be held in place by fixation means (13), while the outer cover plate (11) can be clipped over the inner supporting plate (10), thus concealing the fixation means (13) used to fasten the supporting plate (10).
Abstract:
The invention relates to a fixing frame (1) for mounting ventilation air inlet or outlet dampers to a planar structure such as a ceiling or wall panel, said fixing frame having a body of essentially cylindrical shape and being equipped at its front rim with a collar flange (3) aligned essentially orthogonal to the center axis of the cylindrical body part (2), whereby said panel is machined to have a hole with a diameter and shape essentially equal to that of said fixing frame body part, into which hole the fixing frame is inserted so that its collar flange (3) remains flush with the front surface of said panel, and said fixing frame has a threaded portion (4) projecting radially inward from the inner surface of its cylindrical body part (2) so as to permit a damper with a compatible outer threaded portion to be mounted into said fixing frame. The invention is implemented so that the cylindrical internal surface of the fixing frame (1) has at least two essentially oppositely located grooved sites (5) for alternative mounting of a wire-clip-type damper body into the fixing frame (1).
