A hose bending clamp (10) is described for holding a hose in a desired bent shape. The clamp (10) includes a coil 14 designed to slop over the outside over a section of hose to be bent. Each of the turns (12) of the coil are designed to constrain the hose so as to inhibit it from spreading or kinking as it is forced into the desired shape. A malleable spine (16) is provided in connection with the coil (14) and is designed to bend with the hose into the desired shape and to hold the shape when re...

Metal-plastic multilayer pipe with a plastic inner pipe (30) and a metal sheath (32) around the plastic inner pipe (30), where the metal sheath (32) is of uniform thickness, is applied to the plastic inner pipe (30) so that it completely encircles the plastic inner pipe (30) and a practical plastic outer layer (38), with the feature that the thickness of the metal sheath (32) as compared to the total thickness of all layers of the multilayer pipe (32, 34 and 38), is sufficiently thin that the me...

A rectangular waveguide has a cross section such that twisting or bending does not distort the internal cross section, lips being provided at each corner of the waveguide and the wall sections being shaped such that when viewed from a shorter side each corner has a portion with a substantially T-shaped section, and while viewed from a long side each corner has a pronounced asymmetric T-shaped section.

An annulated tubular sheath which is split down a longitudinal section thereof. According to the invention, a longitudinal strip of the sleeve is made of a flexible material and is disposed in an angular position of 5-180 degrees in relation to the longitudinal section or is disposed in the region of the sheath in which the longitudinal section is made. Preferably, the flexible material is a thermoplastic elastomer. The invention also relates to a method for producing a sleeve by extruding a pla...

The invention relates to a multilayer plastic pipe (1), preferably for use in heating systems. The multilayer pipe comprises an inner core (2) and a barrier layer (6) surrounding the core and preventing oxygen diffusion through the multilayered pipe. The core (2) is made of a material having viscoelastic properties, preferably cross-linked polyethylene, and the barrier layer (6) is surrounded by an outer layer (8) of a material having adhesive properties. The invention also relates to the use of...

An arrangement for enclosing an elongate substrate, e.g. a cable connection includes an outer resilient sleeve held in a radially-expanded configuration by being mounted on an inner holdout member, wherein the holdout member includes a generally tubular member that has a slit extending longitudinally thereof such that application of a force radially thereof causes the holdout member to reduce in circumference and to collapse around the substrate under the action of the recovery force of the oute...

A device for shaping a duct made of plastics material or of deformable elastic material comprises two half-cages molded out of rigid plastics material and fastened together by resilient snap-fastening or hooking, the two half-cages when assembled together defining between them a housing that has the shape which is to be imparted to a portion of the duct. The invention is particularly suitable for mounting ducts of relatively large diameter in the engine compartments of motor vehicles.

A cable assembly includes a plurality of electrical or fiber-optic cables, a spacer, and a collar. The cables are arranged lengthwise in a bundle, which includes a segment having a cross-sectional arrangement organized into a plurality of columnar sections of contiguous cables. Each columnar section has at least one cable. The spacer is disposed between the adjacent columnar sections. The spacer spans substantially entirely across a cross section of the segment of the bundle in one direction. Th...

A continuous drain hose for an electrical appliance having a water outlet is disclosed. The drain hose comprises a first cylindrical end portion being connectable to the water outlet, a second end portion being connectable to a drain pipe and comprising a bellows that is able to form a permanent bend when a temporary bending force is applied thereto, and a flexible corrugated portion connected between the first cylindrical end portion and the second end portion. The bellows is also permanently e...

A hose body is formed, or provided, to a predetermined length and so as to be continuous and contiguous. Articulation means are formed about and in close proximity to the hose body. This is accomplished by forming a wire helix about the hose body so as to either have a different number of turns per unit length of hose for first, second and third portions of the hose body, or by utilizing multiple strands of wire of different thickness for some portions of the helix and not for others, or by form...
