Abstract: A mast assembly (10), a method of deploying a mast (20), a slit locking clamp (50) for a mast and to a support assembly (14) for an extendible member (20) are provided. The mast assembly (10) comprises an extendible mast (20) configurable between a coiled form and an extended form. When extended the mast is resiliently biased in the form of an elongate tube having a slit along its length defined by longitudinal edges of the mast. When coiled the mast is opened out at the slit to a flattened cross section and wound about an axis extending transversely to the longitudinal extent of the mast. A slit locking clamp (50) clamps across the slit in the mast at a position along the length of the mast so as to stabilise one edge relative to the other.

Abstract: The invention relates to a device for unfolding a rolled-up elongate hollow member having: at least one elongate hollow member which has two elongate shell member halves, and an unfolding mechanism which has a fixed base structure and a winding core which is rotatably supported on the base structure and on which the at least one elongate hollow member in a first state is rolled up and compressed and which by rotating moves and unfolds the elongate hollow member from the first state into an unrolled and unfolded second state so that an elongate hollow space is formed between the two shell member halves of the at least one elongate hollow member, wherein the at least one elongate hollow member has as a first end a hollow member root, via which the elongate hollow member is secured to the rotatably supported winding core, wherein the first shell member half of the at least one elongate hollow member is secured in the region of the hollow member root to the rotatably supported winding core, and the unfolding m

Abstract: A roll (54) of compressed materials (14) is provided which has a sleeve (50) formed around a rotatable mandrel (12). The sleeve (50) about which the materials (14) are rolled prevents the roll (54) from radially collapsing. The roll (54) may be removed from the mandrel (12) without tearing or telescoping of the material. In one embodiment the sleeve (50) is corrugated material (38). The corrugated material (38) is around the rotatable mandrel (12) prior to the compressible material (14) being wrapped around the sleeve (50). In another embodiment, the sleeve (58) comprises roll-packing material (32) laminated prior to being wound upon the mandrel (12).

Abstract: A self-cleaning strainer which may be installed upstream of a heat exchanger to prevent debris greater than a critical size from reaching the heat exchanger. The strainer is preferably mounted just upstream of a heat exchanger in order to minimize the possibility of debris reaching the heat exchanger. The strainer comprises a screen element which can be advanced across the flow path of the fluid between two rollers. The screen element is placed so that the fluid must flow across the screen element face to continue through the process pipe; the screen may be perpendicular or parallel to the fluid flow axis of the strainer body or at an intermediate angle to it. Flow blocking members are used so as to direct the flow to pass through the screen element.

Abstract: A device is provided for winding a roll of a fabric web made from organic and/or synthetic fibers and which has a relatively high porous material structure and a high volume per unit area. The device includes a winding bed having a plurality of support rollers and a pressure roller located above the support rollers for exerting a pressure force on the fabric web being wound into the roll. An ascending delivery table has a distal end above the pressure roller. The support rollers and the pressure roller are rotated in the same direction during the winding process. A packing station is provided adjacent the winding bed. The direction of rotation of the support rollers is reversed to move the roll from the winding bed to the packing station.

Abstract: A damper continuous feeding body having a plurality of punched out dampers, each of which is constituted by a viscoelastic body and a restraint body which are laminated on each other, wherein surfaces of the viscoelastic bodies are pasted on a release surface of a continuous liner so that the plurality of dampers are arranged at a predetermined pitch. The damper continuous feeding body allows dampers to be pasted by an automatic machine so as to improve the accuracy of the pasted positions of the dampers and to enhance the efficiency in pasting, and further whereby the dampers can be prevented from being exposed to contamination.

Abstract: A winding core 10 according to the present invention has a cylindrical outer peripheral surface and arranged in a manner that when a web is wound around the outer peripheral surface and so a predetermined pressure acts on the outer peripheral surface, the deformation distortion &ggr;(=&Dgr;R/R) of the outer peripheral surface along the radial direction thereof is equal to or less than 0.001. In this case, &Dgr;R represents the maximum deformation amount along the radial direction of the outer peripheral surface of the winding core and R the diameter of the outer peripheral surface of the winding core upon no occurrence of deformation.

Abstract: Novel fibers have been made from reactor grade isotactic poly-alpha-olefin wherein polypropylene is produced by single-site catalysis and has a melt flow rate of greater than zero to about 5,000, MWD in the range of about 1.0 to about 3.5.

Abstract: A roll up tray for lengths of material and which is particularly suitable for rolling strips of washed turf including a first conveyor to which the turf is delivered and from which the turf can be delivered to a second conveyor which is located therebeneath, a third conveyor adjacent the delivery end of the second conveyor and at an angle thereto and moving in the same direction therewith so that the turf is initially lifted by the third conveyor and is then permitted to fall back thereon so that the turf is formed into a roll. The roll of turf can be delivered in either direction from the tray by moving the second conveyor about a pivot.
