摘要:
A method for installation of a flexible resin impregnable liner for lining a lateral pipe which leads into a main pipe having at one end a flexible collar for installation at the location where the lateral liner meets the main, wherein after installation the collar extends along the interior of the main seating against the opening of the lateral. The flexible liner is installed by inserting the liner into the lateral pipe and using fluid under pressure to expand the lining against the lateral wall to form seals with the collar at the lateral/main pipe junction.

A graphical user interface includes a graphical user interface, which includes an item interface in which at least two items can be listed. In an expanded state, the item interface has a collapse control for bringing the item interface in a collapsed state in which the dimensions of the item interface are partially reduced and at least some of the items are not visible. In a collapsed state, the item interface has a expand control for bringing the item interface into the expanded state.

A TV graphical user interface provided on a TV screen includes a graphical channel changer for enabling a user to select a required TV channel among about 1000 channels carried by a satellite TV system. The graphical channel changer contains a vertical channel bar composed of channel boxes that display numbers and logos of selected TV channels. To switch the TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. Up and down scroll bars, that allow the user to scan through the entire list of TV channels, extend beyond a safe area on the screen provided to accomodate a picture to overscan conditions. A direct access bar is arranged so as to cause the channel boxes to display numbers and logos of a selected group of channels when the user directs the pointing device at the area of the direct access bar that represents the selected group of channels.
摘要:
A method of lining a passageway comprising pulling a first flexible lining pipe sized to the passageway to be lined into the passageway, the first lining tube comprising at least one resin absorbent layer impregnated with curable synthetic resin, and by the eversion into the first lining tube of a second flexible lining tube sized to the first tube inner diameter, to the inner surface of which a second lining tube before eversion is applied an initiator for the resin impregnating the first lining tube whereby, as the second lining tube everts into and along the first tube when in the passageway, the first tube is pressed against the passageway surface by fluid pressure used to evert the second tube, and also the initiator comes into contact with the resin of the first tube and commences and effects cure of the same.

The invention provides a method of applying a resin impregnated lining sleeve to a length of passageway surface wherein the sleeve first of all has a carrier tube everted into the sleeve from one end and out of the other end, the carrier tube is re-inverted to draw the sleeve into the carrier tube and then the assembly of carrier tube and sleeve is positioned in relation to the passageway length to be lined and the carrier tube re-everted to position the sleeve on the surface in the required position. The resin is subsequently cured and the carrier tube removed leaving a hard tubular lining shell on the passageway surface.

The present invention provides a material which comprises a laminate of a fibrous layer such as a felt which can be impregnated with curable synthetic resin, and bonded to the felt is a membrane comprises three layers namely an inner layer of a low softening point material bonded to the felt, a barrier layer which represents a barrier to the aggressive components of the resin such as the styrene, and an outer layer bonded to the outside of the fibrous layer to provide for the application of patches and sealing tapes by heat or solvent welding.

The invention provides for the light curing of a synthetic resin which is light curable, and is arranged as a layer upon the surface of a pipeline or passageway. The curing lamps are enabled to be pulled into the pipeline or passageway by virtue of inserting a tubular member into the passageway which is inflatable by fluid pressure so as to hold the resin layer in position. The lamps pass through the inflatable tubular member so that radiation therefrom will fall on the layer of resin and cure or initiate the cure of the same.

A method of impregnating the inner absorbent layer of a long flexible tube with a curable resin is begun by introducing a mass of the resin into one end of the tube. A window is formed in the impermeable outer layer of the tube at a distance from the resin mass. A vacuum in the interior of the tube is drawn through the window and concurrently the resin mass is pushed toward the evacuated region by passing the tube between a pair of squeezing members. When the flowing resin reaches the vicinity of the window, the window is sealed. Another window is formed in the tube farther downstream of the previously formed window. A vacuum is drawn through the new window while the squeezing members force the resin to flow toward the newly evacuated region. The procedure is repeated until the resin has spread through the entire inner absorbent layer of the tube.
