Abstract: An apparatus and method for patient care and cleaning. Included are semi-disposable pants, a mattress, a care materials inflow preparation unit, a waste fluid container, a control unit, and a remote control device. The body area to be washed is covered with pants, providing a soft container having fittings connecting it to a wash liquid supply and effluent disposal hoses. The waist and femoral regions of the pants are provided with sealing rings for sealing of the space inside the pants during waste handling cycles of the patient care, and unsealing when this cycle is completed. Sensors are located in the pants for remote control of all materials handling functions in the patient care process. The mattress is provided with inflatable chambers that facilitate positioning of the patient's body and creation of a hollow space for bath water, thereby facilitating in-bed bathing of the entire body.

Abstract: A conduit lining system and a method for lining conduits, particularly conduits in need of repair. The system includes a longitudinally extending liner, initially transversely curled in a pre-installation position but being capable of becoming uncurled in an installation position to form a longitudinally extending generally cylindrically shaped liner for placement adjacent an interior surface of a conduit to be lined or repaired. The liner has longitudinally extending locking edges which become mutually engaged as a torpedo-shaped member is inserted within the liner, while in the curled pre-installation position, and the member is moved longitudinally therethrough.

Abstract: An apparatus and method for repairing a damaged host pipe, such as a culvert or other conduit. A trough is positioned over the invert of the host pipe and a longitudinally successive series of ribs are positioned and expanded against the interior of the damaged host pipe and against the trough, the rib having one or more segments and a pair of circumferentially successive flaps hinged together. With a hydraulic jack or other appropriate pushing device, a pushing force is applied against the hinged flaps until the hinged flaps are locked in an installation position. Grout, such as a cementitious grout is then installed in spaces between the trough and the host pipe. Alternatively, the ribs extend transversely beneath the trough, but not beyond the longitudinal edges of the trough, and the trough is anchored to the host pipe.

Abstract: Method and apparatus for internal repair of conduit system. An inner sleeve is employed which is configured to avoid undue pressure being applied to the inner surface of a damaged conduit section as it is expanded into position. A grouting area is defined between the outer surface of the sleeve and the inner surface of the conduit section or sections being repaired. In one embodiment, a layer of open-celled material is placed around the coiled sleeve, which is thereafter impregnated with a quantity of grout. In this embodiment of the invention, each longitudinal end of the sleeve is flared outwardly for contacting the inner surface of the damaged conduit section and for retaining the grout as it is squeezed out of the gasket upon the expansion of the inner sleeve to its expanded and locked position.

Abstract: An apparatus and method for internal repair of pipes and conduits, such as sewer pipes, pressurized water mains, water wells, and natural gas lines. The conduit repair apparatus includes a sleeve with locking mechanism to lock the sleeve in a tubular configuration. The sleeve is made of metallic or rigid plastic sheet having perforations. Some of the perforations are shaped like elongated slots and strips. A number of resilient O-rings are applied over the outer surface of the sleeve. A resilient membrane is applied over the O-rings. In one embodiment, a reinforcement band is used, and an additional layer of O-rings are included between the membrane and the reinforcement band.

Abstract: A method and apparatus for assembling an enclosure, in which the assembly includes a coil of material adapted to be uncoiled to an assembling position. The material can be prestressed to become at least transversely curved in the uncoiled assembling position. In a particular embodiment, the material is also prestressed to curve longitudinally, as the coil is unwound to form a toroidal shape. Further, the assembly can include a plurality of elements positioned within the coil, the elements having a size and shape enabling them to be adapted to be affixed to respective parts of the assembly within the enclosure in respective positions along the length of the material in the uncoiled assembling position to constitute an internal structure for the enclosure. The plurality of elements are coiled with the coil of material for permitting access to the elements for assembling them after the material is uncoiled. The enclosure is adapted to be used in space or terrestrially, on land or underwater, and can be appropriately sealed and pressurized.

Abstract: A pipe repair sleeve and liner with interlocking elements in a form of a coiled sheet which is covered with compressive gasket. An air bag is inserted into the coiled sleeve and moved to the location of the damaged pipe. Once in place, the air bag is inflated. As a result of the inflation, the repair sleeve uncoils and the surrounding gasket is compressed against the damaged pipe. When the air bag is deflated, the sleeve begins to coil and forces a male end of the sleeve into the female end forming a male and female interlocking continuous sleeve inside the pipe. After the repair sleeve is installed in the pipe, the air bag is removed from the sleeve.

Abstract: A collapsible tunnel liner section formed from a number of arcuate segments each connected together by hinges to form a closed loop. In collapsed condition the segments are arranged in a compact stack having a cross section less in its maximum dimension than the internal diameter of the erected liner section. Typically the stack has the appearance of a figure 8, having upper and lower cavities. .[.Air bags.]. .Iadd.Expansion means .Iaddend.are located within these cavities and are expanded to expand the collapsed tunnel liner section into its erected condition. During the expansion the liner section passes through an oversized condition before assuming its final erected condition. This ensures stability for the erected liner section. After erection, grout or other filler material is inserted between the liner section and the wall of the tunnel.
